... Month in review for northeast Oregon and southeast Washington for
the month of January 2016...

... Fairly typical weather for January 2016 in our area...

I. Temperature and precipitation overview

January average temperatures were mainly near to slightly above average
across much of the region for the calendar month ranging from
approximately normal to +2.5 degrees above normal. The only exception
was along the east slopes of the Cascades and near Seneca, or where
temperatures were up to 1 degree below average for the month. Most
locations saw both maximum and minimum temperatures average above
normal for the month, with maximum temperatures mainly between 0 and
1.5 degrees above average. Monthly minimum temperatures were between
0.5 and 2.0 degrees above average, except near Yakima where monthly
minimum temperatures were almost 5 degrees above normal.

Total precipitation was variable across the area for the month, ranging
from about 60 to 90 percent of normal in parts of north central Oregon
and the northeast mountains of Oregon. Meanwhile, precipitation was
above average, ranging from 100 to nearly 200 percent of normal in the
Columbia Basin, Yakima Valley and Kittitas Valley region.

Snowfall was mainly below average in the lower elevations of the region
in january; the one major exception to this was in the Yakima and
Kittitas valleys where above average snowfall continued into January.
Locations such as Pendleton, Walla Walla and La Grande ended the month
with much below average snowfall.

To summarize, conditions were mainly warmer and slightly wetter than
normal across the region for the month, although as noted above parts
of the Blue Mountains in northeast and southeast Washington did have
below average precipitation for the month. Several daily and monthly
records were broken throughout the month; although overall fewer
records were set compared to previous months as temperatures,
precipitation and snowfall were generally within the bounds of a normal
January. See below for more details on these records.

ii. Selected records

The first ten to twelve days of January featured a cold, stagnant and
fairly dry weather pattern across much of the region. The only
exception to this was near Yakima and Ellensburg where a weather system
broke through the Cold Ridge of high pressure to bring a rather
significant snowfall from January 3rd through the 5th. Beyond January 12th
the weather patterned flipped, becoming more progressive, with storm
systems moving through the Pacific northwest every two or three days.
Once this pattern change occurred, the last two weeks of the month also
had generally above average temperatures across the region. In fact,
for the lower elevations, including central Oregon, high temperatures
were in the 40s or 50s just about every day during the second half of
January. There was a larger, more significant storm system which moved
through on January 28th and 29th... .much like previous storms of the
month this one brought another round of rain, very high elevation snow,
and gusty winds. More details on these events, including Sample snow
amounts, rain amounts and peak wind gusts can be found in the
significant weather section below.

Very few, if any monthly record high temperatures were recorded around
the region in January. Therefore, listed below are the location and
daily record high temperatures set in January 2016:

The mean synoptic pattern for the month of January 2016 was
characterized by a large, anomalous trough of low pressure south of
Alaska, extending along the West Coast of the US. There was an upper
level ridge of high pressure located across northern Alaska and much of
Canada during this time. This allowed a west to southwest flow to
dominate in the Pacific northwest for the month. The flow of moisture
into the Pacific northwest was not quite as strong as it was in
December, but numerous weather systems were still able to affect the
region during the month. These weather systems brought near average
amounts of rain and snow to most of the area, with northern California
and central Washington receiving the most precipitation compared to
average. This Pacific maritime flow also allowed temperatures to remain
rather mild through the month (at least for January standards). Very
few, if any monthly record low temperatures were recorded around the
region in January. Therefore, listed below are the location and daily
record low temperatures set in January 2016:

City daily record min T previous daily record min T

Seneca, or -21 on 01/02/2016 * -31 in 1971

*honorary mention, not a daily record, as it reached -31 on this date
in 1971

Precipitation totals were generally rather variable across the
region in January. Totals ranged from approximately 70 to 110
percent over central and northeast Oregon, to upwards of 200 percent
of normal in parts of Yakima & Kittitas counties. With this high
degree of variability only a few daily precipitation records were
broken throughout the month. Listed below is the location, rank,
January 2016 daily precipitation amount and the previous or current
January maximum daily precipitation record:

Several locations had their top 20 wettest januaries on record. Listed
below is the location, rank, January 2016 precipitation total and the
current January monthly precipitation record:

Moxee City, WA #13 1.60 inches 2.89 inches in 1995
Pelton dam, or #18 1.81 inches 4.31 inches in 1970

With multiple storm systems depositing snow across some parts of the
region a few locations were able to increase their monthly snow total
into the top 20 ever recorded during the month of January. Listed below
is the location, rank, January 2016 snow total and the current or
previous maximum January monthly snowfall record:

City rank Jan 2016 current Jan Max
                         monthly snowfall monthly snowfall

Easton, WA #18 17.5 inches 96.0 inches in 1907
Yakima, WA #19 11.7 inches 26.6 inches in 1950

Even with multiple storm systems moving through the region during the
month of January many locations had temperatures that were too warm to
support snow. Therefore, several locations actually set or tied records
for the least snowy January on record. Listed below are the location,
rank, January 2016 snow total, lowest January snowfall on record, and
the number of other years on record that received 0.0 inches of snow
for the entire month of january:

Iii. Significant weather

There were multiple significant weather events across the area during
the month of January, occurring throughout the entire month. There were
several rain and snow events, cold air outbreaks, along with a few
gusty wind events. For the second month in a row January started off
quite cold across our region. From January 1st through the 3rd
temperatures remained well below average levels in most locations.
Several locations were able to set new daily record low temperatures
during this period. Although quite cold, very few if any monthly cold
records were reported during this time.

Listed below are Sample minimum observed temperatures during this
event:

Location coldest observed temperature

Seneca, or -21 degrees
Sunriver, or -13 degrees
Meacham, or -9 degrees
Bend, or -8 degrees
Sisters, or -6 degrees
Cle Elum, WA -6 degrees
Joseph, or -4 degrees
Ellensburg, WA -4 degrees
John Day, or -2 degrees
Long Creek, or -1 degree
La Grande, or -1 degree
Yakima, WA 0 degrees
Redmond, or 1 degree
Prineville, or 2 degrees
Goldendale, WA 3 degrees

From January 3rd through the 5th a storm system with abundant moisture
moved over our area from January 3rd through the 5th. This storm system
moved over lingering cold air, and was therefore able to produce some
significant snowfall totals across parts of the region. The heaviest
snow fell along the east slopes of the Cascades, the Yakima Valley, and
Kittitas Valley region. Light snow, mixed with freezing rain also
affected the Columbia Basin and Blue Mountain foothills.

Listed below are the 3 day snowfall totals and the highest observed
snow depth during the period at select locations:

Location 3 day snow total Max observed snow depth

Trout Lake, WA 7.0 inches 33 inches
Cle Elum, WA 6.0 inches 16 inches
Yakima, WA 5.0 inches 11 inches
White Salmon, WA 4.2 inches missing
Goldendale, WA 4.0 inches 11 inches
Ellensburg, WA 3.7 inches 10 inches
Easton, WA 3.0 inches 41 inches
Prosser, WA 1.5 inches 1.5 inches
Richland, WA 1.0 inches 1.0 inches
Kennewick, WA 0.5 inches 0.5 inches
echo, or 0.3 inches trace
Pendleton, or 0.2 inches trace

After a break in the weather, the pattern once again turned much more
active heading into mid-month. From January 11th through the 13th several
Pacific weather systems moved through the area, bringing large amounts
of rain and snow (to parts of the area). By this time in the month
temperatures had begun a warming trend as Pacific air replaced any
leftover Canadian or Arctic air that was in place. Therefore snow only
in the higher elevations, a few parts of central Oregon, and once again
along the east slopes of the Washington Cascades. Listed below are some
Sample snowfall totals from this event:

Location 3-day rain total 3-day snow total

Walla Walla, WA 0.29 inches 0.0 inches
Meacham, or 1.06 inches 6.0 inches
The Dalles, or 0.21 inches 0.0 inches
Ellensburg, WA 0.19 inches 1.3 inches
Hermiston, or 0.17 inches 0.0 inches
Pendleton, or 0.33 inches trace
Pasco, WA 0.28 inches 0.0 inches
Yakima, WA 0.31 inches 3.5 inches
Cle Elum, WA 0.39 inches 3.5 inches
Easton, WA 0.60 inches 4.0 inches
Goldendale, WA 0.48 inches 0.3 inches
Redmond, or 0.24 inches 0.2 inches
Bend, or 0.11 inches 1.0 inches

A series of low pressure systems once again moves through the forecast
area. This storm system brought ample amounts of precipitation to the
entire area, even more than the previous storm system just days before.
Moderate to even heavy snow amounts were once again observed near
Yakima, Ellensburg, Easton and into the Blue Mountains. Other locations
were spared the snow, but received a moderate rainfall. Listed below
are some Sample storm total snow totals along with Sample storm total
precipitation amounts from around the region.

Location storm total precipitation storm total snow

Walla Walla, WA 0.66 inches 0.0 inches
Meacham, or 1.41 inches 5.0 inches
The Dalles, or 1.09 inches 0.0 inches
Ellensburg, WA 0.87 inches 6.6 inches
Hermiston, or 0.57 inches 0.0 inches
Pendleton, or 0.62 inches 0.0 inches
Pasco, WA 0.53 inches trace
Yakima, WA 0.98 inches 3.0 inches
Cle Elum, WA 1.39 inches 8.0 inches
Easton, WA 1.69 inches 12.5 inches
Goldendale, WA 1.27 inches 0.0 inches
Redmond, or 0.47 inches 0.0 inches
Bend, or 0.61 inches trace
John Day, or 0.32 inches 0.0 inches
La Grande, or 0.16 inches 0.0 inches


To round out the end of the month another storm system pushed
through our area on January 28th and 29th. This storm brought warmer
air and rising snow levels. Snow levels at times reached 6000-8000 feet,
allowing some significant, but short lived snow melt to occur even
in the mountains. This snow melt combined with a moderate rainfall to
bring some rises on area rivers and streams. Little to no flooding
was reported as the snowpack froze back up the last day of the
month. Winds were also strong and gusty behind the sharp cold front
on January 29th. Listed below are some 2-day rainfall totals and
highest peak wind gust during this period:

Location 2-day precip location peak wind gust

Walla Walla, WA 0.33 inches Pendleton, or 50 mph
Meacham, or 1.21 inches Walla Walla, WA 49 mph
The Dalles, or 0.64 inches La Grande, or 49 mph
Ellensburg, WA 0.27 inches Lexington, or 48 mph
Hermiston, or 0.23 inches Redmond, or 47 mph
Pendleton, or 0.38 inches Prineville, or 47 mph
Pasco, WA 0.15 inches Hermiston, or 46 mph
Yakima, WA 0.27 inches John Day, or 41 mph
Cle Elum, WA 0.29 inches Pasco, WA 41 mph
Easton, WA 1.05 inches the Dallas, or 35 mph
Goldendale, WA 0.50 inches Yakima, WA 31 mph
Bend, or 0.26 inches Moro, or 29 mph

The latest drought monitor shows improvement across the Pacific
northwest, with only a small area of d1, or moderate drought
lingering in eastern Washington. Most of eastern Oregon has now been
reduced to only d1 to d2 drought status. However, there remains a
small area of d3 (severe drought) in south-central Oregon within the
Klamath River basin. The seasonal drought outlook from CPC indicates
drought persisting for much of our area (but likely not becoming
worse). The only exception is in southern Oregon where drought
removal or improvement is likely. This may be updated next month to
reflect recent trends in precipitation and snowpack across our area.

Current snow water equivalent (swe) is running mainly above average
across the Pacific northwest. The only exception to this was over
eastern Washington where swe was between 90 to 99 percent of normal to
date. The rest of Washington and Oregon had swe values generally
between 100 to 155 percent of normal.

Looking ahead to the rest of February the climate prediction center
(cpc) is calling for a greater chance to see above normal temperatures
across the inland Pacific northwest. The CPC is calling for higher
chances of below normal precipitation amounts over much of the region,
with the highest confidence for below normal precipitation amounts in
eastern Washington and extreme northeastern Oregon. Across far
southwestern Oregon, the CPC is predicting equal chances for above,
below, or near average precipitation amounts in February. Please keep
in mind that these forecasts are for the entire month averaged out, and
that daily weather conditions will undoubtedly vary.

NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Pendleton or

Updated aviation discussion 


Short term...tonight through Friday...the upper level ridge over 
the region is beginning to weaken as weather systems off the coast 
bump up against it. The ridge will slowly flatten over the next 
couple of days allowing a southwest flow aloft to bring some 
moisture into the region starting as clouds overnight and Wednesday. 
There will be some light precipitation spreading into western 
Washington and Oregon on Wednesday eventually reaching the 
Washington Cascades Wednesday night and Thursday. The upper level 
ridge will finally break down on Friday allowing a cold front to 
push through the forecast area Friday increasing the chance of 
precipitation for the entire area. Snow levels will remain high so 
expecting mainly rain through Friday. 


Long term...Friday night through Tuesday...pressure pattern aloft 
across northeast Pacific and the Pacific northwest becomes very 
progressive with a series of Pacific weather systems tracking 
eastward through the region through the period. As such snow levels 
will be unseasonably high resulting in precipitation being in the 
form of rain each day. The first upper level trough approaches the 
Cascades Friday night and then sweeps a strong cold front through 
the forecast area on Saturday. Tightening surface pressure gradients 
accompanying the cold front will produce breezy conditions beginning 
soon after daybreak on Saturday morning with breezy winds continuing 
through Saturday afternoon. The upper level trough exits into 
Idaho/Montana Saturday afternoon followed by a flat upper level 
ridge of high pressure building over the Pacific northwest Saturday 
night, which will usher in a warm front and attendant warm air 
overrunning rain for Saturday night, which then persists through 
Sunday afternoon. As the ridge amplifies Sunday night and Monday... 
George Washington's birthday...sinking air associated with the ridge 
will yield dry conditions at lower elevations and a low chance of 
rain over the higher mountains. Monday night and Tuesday the ridge 
will still be over the interior Pacific northwest for dry conditions 
in central Oregon and east central Oregon, but with a low chance of 
rain in the mountains on Tuesday. Polan

Aviation...00z tafs...VFR conditions will continue through this 
evening. Then a strengthening inversion will trap and increase 
moisture in the boundary layer producing low ceilings and fog due to 
increasing areal coverage of low stratus and fog in the lower 
Columbia Basin and adjacent valleys beginning around midnight and 
continuing well past daybreak on Wednesday. As such conditions are 
expected to deteriorate at kykm, kpsc, krdm and kbdn becoming vlifr 
at krdm and kbdn, with kpsc and kykm becoming LIFR. 


Conditions at kykm will improve to IFR by around 20z-21z tomorrow. 
Conditions at kpsc will improve to VFR by 21z. 
Conditions at krdm and kbdn should improve to VFR by around 16z-17z. 


I kept kdls, kpdt and kalw at VFR for the next 24 hours, as guidance 
showed downslope drainage winds and/or mixing in the boundary layer 
in combination with a drier boundary layer initially, so these 
factors should work against formation of fog and low stratus clouds 
at those taf sites tonight. If visibility does lower to 5-6sm with 
localized MVFR conditions at kdls, kpdt and kalw, these sites will 
be amended or their forecast updated based in new scheduled taf 
issuances later this evening if new model forecast guidance changes. 


Surface winds less than 10 kts for the next 24 hours. Polan
