NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
300 PM PDT Wednesday Jul 23 2014 


Synopsis...an upper low will produce showers and isolated 
thunderstorms across western Washington tonight as it moves inland 
from the offshore waters. Showers will decrease Thursday as the low 
moves northeast into Alberta. High pressure will build over the 
region on Friday...bringing sunny warmer weather through the middle 
of next week. 


&& 


Short term...a 5590 meter upper low is over the Washington offshore 
waters near 47n/126w this afternoon. Widespread showers have been 
falling across western Washington. Storm total rainfall exceeds an 
inch in some areas -- mainly over the west part of the Puget Sound sound 
region...west slopes of the Cascades...and southwest interior. The 
daily rainfall record for July 23 has already been broken at 
SeaTac...Bellingham...and Hoquiam. The thunderstorms that developed 
early this morning moved northeast...and at least in our forecast 
area they have been limited to the Cascade crest since late morning. 


The upper low will continue tracking eastward...moving into western 
Washington this evening and lifting into southern British Columbia 
late tonight. Widespread showers will continue...but rainfall rates 
will generally decrease overnight. Another 0.25 to 0.50 inch is 
likely over much of The Lowlands...with 1 to 2 inch amounts common 
over the mountains. The snow level will be around 7000 feet. 


There is a chance of thunderstorms through tonight...as the air mass 
is still moist and unstable with diffluent southerly flow aloft. It 
is a bit surprising that more thunderstorms have not developed yet 
over our area...western Oregon...or offshore of the Pacific 
northwest. The air mass should be at its most unstable through this 
evening though...and the small comma in the vicinity of the upper 
low itself could help renew convective activity. 


The flow aloft will veer to westerly again Thursday as the upper low 
tracks into southern Alberta. The air mass will stabilize and begin 
to dry...but moist onshore low level flow will continue and a Puget Sound 
sound convergence zone will probably develop. On the whole showers 
will decrease Thursday...with some sunbreaks likely over The 
Lowlands. 


Westerly flow aloft will continue over the forecast area Thursday 
night and Friday...but upper heights will start to rise as a ridge 
builds northward along the Rocky Mountains from The Four Corners 
high. There will likely be some marine layer clouds to start the 
day...but they will give way to mostly sunny skies at least over the 
interior. 


The upper ridge will build further Friday night and Saturday...with 
500 mb heights climbing to around 5820 meters. Onshore flow will 
weaken. Saturday should be warmer and sunny with some night and 
marine layer clouds mainly along the coast. Mcdonnal 


Long term...the upper ridge will build over the Rocky Mountains 
through at least Monday...with 500 mb heights over western 
Washington climbing to around 5880 meters. Surface high pressure 
offshore and thermally-induced low pressure east of the Cascades 
will maintain very weak onshore flow. Some model runs -- mainly of 
the GFS -- have suggested that the trough will weaken with a marine 
push around Tuesday night. However the most recent runs maintain the 
upper ridge through midweek. Bottom line is this will be a stretch 
of sunny and warm weather. Mcdonnal 


&& 


Climate...there have been 23 July days with 0.50 inches of rain or 
more since records started at sea-tac in 1945. Only 3 of those days 
have been since 2000...0.65 inches on July 16th 2001....0.60 inches 
on July 20th 2012 and 0.58 inches on July 7th 2002. The record for 
the wettest July day at sea-tac is 0.85 inches on July 13th 1981. 
The wettest July day on record in Seattle is 0.98 inches on July 5th 
1897 when records were kept at the federal building downtown. Felton 


&& 


Aviation...an upper level low just off the coast will move inland 
this evening then northeast tonight. Strong southerly flow aloft 
will become light tonight...then strong northwest late. At the 
surface moderate onshore flow will develop tonight and continue 
Thursday. Air mass unstable and moist all levels. 


Satellite imagery shows some eastward movement of the main weather 
system and there has been some clearing on the South Coast. This 
will continue into the evening. Some return flow showers are likely 
on Thursday especially over northern sections. Ceilings have been 
all over the place today but currently are mostly VFR. Should be 
mostly VFR going forward with occasional excursions to MVFR in 
showers. General improving trend will begin about middle day Thursday. 


Ksea...VFR ceilings except MVFR in showers. An isolated thunderstorm 
is just barely possible this evening. Improving trend after about 
20z Thursday. Southwest wind 10g20 knots tonight and Thursday. Chb 


&& 


Marine...a surface trough off the coast this afternoon will weaken 
and move inland tonight. It should still have enough punch to bring 
moderate onshore flow tonight resulting in Small Craft Advisory 
southwest or west winds in most zones including Puget Sound sound. Onshore 
flow becomes stronger Thursday. For now have indicated 20-30 knots 
westerlies in the Strait but gales seem possible there on Thursday. 


After Thursday the normal Summer pattern returns with onshore flow 
strong enough for Small Craft Advisory westerlies in the Strait at 
times. Chb 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...Small Craft Advisory all waters except central and north inner 
coast.
