Area Forecast Discussion

National Weather Service Seattle WA

328 AM PDT Mon Apr 23 2018



.SYNOPSIS...An upper ridge will build over the area today and 

remain through Thursday, bringing a stretch of sunny days to 

Western Washington. Low level offshore flow will result in the 

warmest weather since last September, with highs in the 70s over 

much of the area. An upper level low will approach from the south

late in the week bringing a return to more seasonal weather for 

the weekend.



&&



.SHORT TERM...Satellite imagery shows the beginning of the warm

spell for western Washington right on track this morning with an

upper level ridge building over the area. At the surface KOTH-KSEA

gradient already down to -6 mb with the cross Cascade gradient at

10z down to near plus 1 mb. The transition to offshore flow is in

progress. Under clear skies temperatures at 3 am/10z were in the 

mid 30s to mid 40s.



Nothing new in the 00z model run with the warm spell for western

Washington scenario remaining intact in the short term. Upper 

level ridge over the area today will remain in place through 

Wednesday. Cross Cascade surface gradient going negative today and

will remain negative into Wednesday. Cross Cascade peaking out 

around -6 mb Tuesday morning giving the Cascade foothills some 

breezy ( 15 to 25 mph ) easterly winds to start the day. 

Temperatures aloft warming each day with the 850 mb temperatures 

starting out in the plus 2 to 4C range this morning rising to 

around plus 8C this afternoon, plus 10 to 12C Tuesday afternoon 

and to plus 12 to 14C Wednesday afternoon. Highs warming into the 

60s and lower 70s today, 70s on Tuesday and 70s with possible 

lower 80s on Wednesday. The exception will be near the Strait of 

Juan de Fuca where the northeasterly winds coming off the cool 50 

degree water in the Strait will keep highs in the 60s. Lows will 

warm each morning with mid 30s to mid 40s Tuesday, 40s and lower 

50s Wednesday and Thursday morning.



.LONG TERM...Extended model solutions are once again inconsistent

beginning Thursday night into the weekend. On Thursday low level

offshore flow comes to an end with the transition to onshore flow

late in the day. This will cool off the Coast dramatically with

highs in the interior similar to Wednesday's readings. Both the

ECMWF and GFS remain at odds with what to do with a shortwave

spinning out of the upper level low over northern California. The

GFS has the shortwave rapidly intensifying Thursday night over 

the area with over a half inch of rain from about Seattle south. 

The ECMWF is much weaker, slower and further south with this 

feature keeping it mostly over Oregon and southwest Washington 

Friday night into Saturday. The ECMWF then develops an upper level

low to the north of Washington on Sunday while the GFS has a weak

open trough. Both models transition the low level flow to onshore

Thursday night and Friday cooling high temperatures over the 

interior back down into the 60s with highs back to near normal, 

mid 50s to lower 60s for the weekend. With the lack consensus 

precipitation wise in the models will stay with the broadbrush 

chance of showers forecast for Friday through Sunday. Felton



&&



.AVIATION...An upper level ridge axis is along the coast this 

morning with light northerly flow aloft. The air mass is dry and 

stable. The flow aloft will shift to light southerly tonight as the 

ridge axis shifts east of the Cascades. Near the surface, high 

pressure over interior British Columbia will combine with thermally 

induced low pressure along the coast for increasing low level 

offshore flow. VFR expected throughout the region.



KSEA...VFR with N-NE wind 5 to 10 knots rising to 10 to 15 knots 

during the afternoon hours.     27



&&



.MARINE...High pressure over British Columbia and Eastern

Washington along with thermally induced low pressure along the 

Oregon and Washington coasts will persist until about Thursday

morning. This will lead to northerly offshore flow. On Tuesday 

morning, small craft-strength easterlies are forecast at the West 

Entrance near Cape Flattery. 



The thermal pressure trough will move inland on Thursday, 

followed on Thu night and Fri by onshore flow.



&&



.CLIMATE...There is a chance Seattle could reach 80 degrees in the

middle of the week. Days in the 80's in April are rare in Seattle

with only 16 since records started at Sea-Tac in 1945. 25 percent

of the April days in the 80s on record at Sea-Tac were 2 years 

ago with the record setting 4 in a row from April 17th through the

20th that included the warmest April day on record, 89 degrees on

the 18th. Felton
