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 
950 am PDT sun may 1 2016 


Synopsis...a strong ridge of high pressure resides over western 
Canada and a broad upper low over the intermountain region and 
southwestern U.S. This pattern will usher in warm offshore flow 
today...with temperatures well above normal at inland locations and 
the coast. This pattern begins to break down 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...satellite imagery shows clear skies around the region 
this morning. The exception is some cumulus developing along the 
Oregon Cascades from about Detroit southward. An unseasonably strong 
upper level ridge of high pressure remains over western Canada and a 
broad upper low sits over the intermountain and southwest US. A 
thermal low will also build northward along the coast today. 
Overall...expect very pleasant Spring weather today with 
temperatures in the middle 70s to around 80. The coastal region should 
also see temperatures near 80 this afternoon as we have deep easterly flow 
over the region. 


The thermal low along the coast will push offshore tonight and lift 
northward off the coast as a closed thermal low Monday. As the low 
shifts northward...models show a southerly wind reversal spreading 
up the coast behind the thermal low during the day on Monday. At 
this time...there is very little stratus along the California coast...so it 
is hard to tell just how much fog and low clouds will accompany the 
wind reversal. Will look at this more closely this afternoon. 
Nonetheless...the switch to S-SW flow will cool the coast 
considerably on Monday and Tuesday. 


By Monday afternoon...models show enough instability and moisture 
arriving for the threat of convection. As usual...the best chance 
for thunder will be along the Cascades where the elevated heat source 
can break a weak cap. There is also some instabilty and a fair amount 
of cape in the valley Monday coupled with S-southeast steering flow...so there 
is also a threat of thunderstorms in the valley Monday evening and Monday 
night. 


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. Tw 


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 to reach konp close to 12z Monday but will 
not include in forecast at this time. 5sm visibility at kast 
still 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 25 knots over eastern approaches through early 
evening. Bowen/mh 


&& 


Marine...a thermal trough over the south Oregon coast will weaken 
this morning with winds continuing to ease over the waters. Winds 
have dropped below 20 knots and dominant periods have rebounded as a 
result...back up to 12 to 14 seconds. Will let the Small Craft 
Advisory for seas expire as seas are no longer square and should 
remain 6 to 8 feet today. Will also cancel the advisory for winds. 
Will see some potential for gusts to 25 knots off coastal gaps this 
afternoon and evening due to offshore flow...but will likely be 
too localized for a Small Craft Advisory. Nonetheless...mariners 
should be aware of these increased winds near coastal gaps. 


The thermal trough shifts off the coastline and over the waters 
today...setting up for a southerly wind reversal to push up the 
coast tonight into Monday which 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. Bowen/mh
