Severe Weather Alert Descriptions

 Record Report  Statement as of 6:30 am PDT on May 1, 2016


... April 2016 GOES in the books as warmest April on record for pdx...

... April 2016 temperatures were about average... for may...

... This is the 9th time Portland Airport has set or tied a record
for warmest average monthly temperature since 2014...


Now that April 2016 has come to an end... it is official now that
Portland Airport has set a new monthly record for warmest April
since records began in 1940. The monthly average of 57.8 degrees
shattered the previous April record of 56.3 degrees set back in 2004
by a degree and a half.

To put this into further context... the average monthly temperature
for the month of may is about 58 degrees. In other words... April
2016 was about as warm as an average may... especially impressive
considering Spring is a transition season where monthly averages
ramp up quickly from winter to Summer.

Record breaking warmth has not been a stranger to Portland the past
couple years... in fact April 2016 is now the 9th month that has set
or tied a record for warmest average monthly temperature since the
beginning of 2014. Framed another way... about 30 percent of the
months since January 2014 have either tied or set their respective
records.

Here is an updated list of the records for warmest average
temperature for each calendar month...

                                              1981-2010
month year / record normal
-----------------------------------------------------------------
January 1953 / 47.3 degrees f 41.4 degrees f
February 2016 / 49.3 43.8
March 2015 / 52.4 48.2
April 2016 / 57.8 52.3
may 1992 / 63.1 58.3
June 2015 / 70.3 63.6
July 1985 / 74.1 69.2
August 2014 / 73.1 69.5
September 2014 / 67.6 (t-1994) 64.5
October 2015 / 60.1 (t-2014) 54.9
November 1995 / 51.7 46.6
December 1950 / 46.4 40.4


It is important to note that the period of record for Portland
Airport began in 1940. Sites with longer periods of record... such as
Salem or Eugene... did not set new April records due to very warm
aprils in 1926 and 1934. However April 2016 still fell in the top
five for most of our climate sites.

May is off to a head start with high temperatures expected to reach
the lower to mid 80s today and Monday... about 15 to 20 degrees above
normal.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
348 am PDT sun may 1 2016 


Synopsis...the month of may is starting off with yet another round 
of unseasonably warm weather for southwest Washington and northwest 
Oregon. A Rex block pattern is setting up over western North 
America...with strong upper ridging over western Canada and a broad 
upper low over the southwestern United States. This will usher in 
warm offshore flow today...with temperatures well above normal all 
the way to the coast. This pattern begins to break down a bit Monday 
as a Pacific cold front slowly approaches the coast. This should cool 
down the coast Monday...with cooler temperatures spreading inland 
Tuesday and Wednesday. Shower chances will increase as the front 
approaches...with isolated thunderstorms possible for much of the 
forecast area late Monday into Tuesday. Showers continue into 
midweek...then models hint at another warming and drying trend 
developing by next weekend. 


&& 


Short term...after the warmest April on record since the 1920s or 
1930s...may begins with another round of unseasonably warm weather 
for southwest Washington and northwest Oregon. A Rex block pattern is 
developing as unseasonably strong upper ridging takes residence over 
western Canada and a broad upper low sits over the southwestern 
United States. Offshore pressure gradients appear to be holding off 
until a weak and dry upper disturbance retrogrades east to west 
across Oregon. The vortmax associated with this disturbance is tough 
to pick out on water vapor imagery due to how dry the air mass is... 
but it presently appears to be over Baker and Malheur counties in 
southeast Oregon. Expect an uptick in east winds today once this 
vortmax moves through later this morning. The afternoon should have a 
bit of a warm breeze for most of the County Warning Area...the 06z NAM remains 
consistent with previous runs in bringing 25-35 knots of easterly flow 
at 850 mb along with good mixing. Exposed areas may see some 30-40 
miles per hour gusts...but most of the district should see gusts in the 20-30 
miles per hour range this afternoon. The east winds will bring a quick rise in 
temperatures once they begin. With 850 mb temperatures rising to +11 degree c...highs 
today should be in the middle 70s to lower 80s today all the way to the 
coast. 


East winds appear to become a bit more constricted through The Gorge 
tonight and early Monday as the synoptically driven easterly flow 
aloft breaks down and veers more to the south...leaving surface 
pressure gradients as the only driver for the east winds. This should 
allow thermal low pressure...initially pushed offshore by todays 
offshore flow...to lift northward off the coast as a closed thermal 
low Monday. In turn...models show a significant southerly wind 
reversal spreading up the coast behind the thermal low as Monday 
progresses. Since there is presently very little stratus along the 
California coast...it is tough to tell just how much in the way of 
fog and low clouds will come with the wind reversal. Cloud cover or 
not...the Switch Back to S-SW flow will probably cool the coast 
considerably on Monday. 500 mb heights will not be all that high 
along the coast Monday...at least not when compared to the past 
couple warm spells. Model average seems to be somewhere near 570 dam. 
The lower heights may allow the marine layer to deepen enough to cool 
down Eugene on Monday as low-level flow turns southwesterly...or 
maybe not. MOS guidance seems fairly insistent on keeping Eugene 
unseasonably warm...so we left temperatures near 80 degrees at Eugene 
Monday. Confidence is higher for areas Salem northward that Monday 
will stay in the 80s for the inland valleys...as it appears doubtful 
the marine layer will have a substantial impact that far north by Monday 
afternoon. 


By Monday afternoon...models show enough instability and moisture 
arriving to consider convection. As usual...the best chance for 
thunder will be along the Cascades...where odds are best that 
surface-based convection can break a weak cap due to the elevated 
heat source. Model mixed-layer cape is not quite as impressive on the 
NAM as the model was showing last night...but 500-1000 j/kg is still 
impressive for our area. Nocturnal inversions will probably result in 
a bit of a cap for the Willamette Valley...with 100-200 j/kg of cin 
per the 06z NAM. This may be difficult to overcome...so lowlands may 
have to rely on convection starting in Cascades or Coast Range then 
drifting over the coast or inland valleys via S-southeast flow aloft. Also 
notable in model soundings is how dry the air mass remains Monday 
afternoon below 700 mb...00z GFS shows Portland nearly mixing down 
dry adiabatically all the way from 700 mb. Should there be any 
organization to convection Monday...this could assist in producing 
some strong downdrafts and outflow. The potential for elevated 
convection is not zero Monday night/Tuesday morning...but also does not 
look quite as good as it did 24 hours ago with latest runs only 
showing weak...thin cape aloft or a neutrally stable air mass. Latest 
runs are slowing the approach of the Pacific cold front 
slightly...which seems reasonable given the blocking pattern. This 
would likely keep warmer/drier air aloft a little longer and make it 
more difficult for elevated convection to develop. Regardless... 
whether it be from remnants of surface-based convection in the evening or 
elevated convection overnight...felt it would be prudent to carry a 
slight chance of thunder overnight Monday night throughout the County Warning Area. 


Tuesday will be a transition day back to more seasonal early may 
weather as onshore flow returns. This should result in a 10-15 degree 
cooldown inland Tuesday. Increasing low-level moisture and the 
approach of the front will likely kick off more shower activity 
Tuesday...though model soundings continue to limit the potential for 
deep convection west of the Cascades. Will hold on to the slight 
chance thunder Tuesday Coast Range eastward...but the best chance 
appears to be along the Cascades as low levels become increasingly 
stabilized by the marine layer. 


Another climate note this morning...since Portland Airport records 
only go back to 1940...pdx shattered their record for the all-time 
warmest April on record with an average temperature of 57.8 degrees 
for the month. This is 5.7 degrees above normal and 1.5 degrees 
warmer than the previous record of 56.3 degrees set in 2004. Sites 
with longer periods of record did not break the all-time April 
record...it appears 1926 and 1934 also had extremely warm April 
temperatures. Will try to get a public information statement or 
record event report out with details later this morning. Weagle 


Long term...no changes. Previous discussion follows... 
Tuesday night through Saturday. Broad upper trough remains over the 
eastern Pacific just off the California coast...providing for south 
to southwest flow aloft over the region. This will keep shower 
chances in place through Thursday. Thunder chances Tuesday night and 
Wednesday afternoon/evening will be greatest in the Cascades and 
foothills...but latest models suggest enough instability to keep a 
slight chance mention for the Willamette Valley. May not be enough of 
a trigger to tap into this...but given the potential in the model 
soundings feel a slight chance remains warranted. Expect some warming 
on Friday and Saturday...with perhaps some dry conditions... as the 
upper low migrates eastward into the Great Basin and high pressure 
building into the Gulf of Alaska as Rex block develops over the 
region. However...maintained the forecast along the lines suggested 
by a blend of models as the European model (ecmwf) continues to remain with a more wet 
solution and some spread in the GFS ensemble members. 


&& 


Aviation...increasing offshore flow will bring VFR conditions to 
all taf sites through 12z Monday. However there is increasing 
chances for IFR stratus may reach konp close to 12z Monday but will 
not include in forecast at this time. 5sm visibility at kast 
seems suspicious based on web cameras so kept them VFR even though 
the observations suggest otherwise. 


Kpdx and approaches...increasing offshore flow will bring VFR 
conditions through 12z Monday. Easterly winds will increase midday 
with gusts to 20 knots over eastern approaches through early 
evening. /Mh 


&& 


Marine...a thermal trough over the south Oregon coast will weaken 
this morning easing winds over the waters. Currently north winds 
are gusting 25 to 30 knots south of Cascade Head and west of 10 nm. 
06z ascat pass showed this well. The ascat data so showed weaker 
winds north of Cascade Head so have dropped the Small Craft 
Advisory in that area. Dominant periods continue around 7 seconds 
at buoy 46050 off of Newport so will continue the advisory for 
steep seas through 9 am for the waters south of Cascade Head. 


The thermal trough shift off the coastline and over the waters 
today setting up for a southerly wind reversal to push up the 
coast tonight into Monday and could briefly bring a period of 20 
to 25 knots wind gusts not a clear signal for advisory at this time 
but will have to monitor. Otherwise...an upper level trough 
splitting and heading south of the region should bring a return to 
a northerly wind pattern towards the middle of next week with 
Small Craft Advisory level wind gusts of 25 to 30 knots possible. 
High pressure then may shift more squarely over the northeast 
Pacific late in the week and focus northerly winds across the 
central Oregon waters. Even though seas look to remain under 10 feet 
indefinitely...seas will likely become fresh swell/wind dominated 
during the middle to latter half of the work week so it still 
looks a bit choppy and rough for smaller boats. /Mh /neuman

Washington...none. 
Pz...Small Craft Advisory for winds until 11 am PDT this morning for 
waters from Cascade Head to Florence or from 10 to 60 nm.
