Area Forecast Discussion National Weather Service Seattle WA 843 PM PDT Mon Apr 12 2021

UPDATE. The current forecast remains on track for this evening and no changes are planned.

PREV DISCUSSION. /issued 210 PM PDT Mon Apr 12 2021/

SYNOPSIS . A few showers are possible near the Cascade Crest through early this evening due to some moisture and instability of the air mass over Eastern Washington. For Tuesday and Wednesday an upper ridge will build into British Columbia while an upper level low develops over the Great Basin. Dry weather and a warming trend will occur into the weekend with offshore flow over Western Washington and a warming air mass.

SHORT TERM /TONIGHT THROUGH THURSDAY/ . An upper ridge will nudge into British Colombia through tonight and Tuesday as an upper trough drops south through Eastern Washington and then into Oregon. There is a chance of a few showers near the Cascade Crest through early this evening from the cumulus building up over Eastern Washington-- which are drifting westward this afternoon. The upper ridge will strengthen across British Columbia and Alberta Tuesday and Wednesday while an upper low develops over the Great Basin. At the surface, low level offshore flow will be the rule and and temperatures will rise a few degrees each day.

LONG TERM /FRIDAY THROUGH MONDAY/ . Dry warm weather through Sunday will give way to increasing onshore flow and cooler weather kicking in around Monday of next week. The weekend will see temps peak--in fact, the record high for the 17th of April at Sea-Tac airport is 80 degrees set in 2016. We have a forecast of 76 for Saturday at the airport and naturally there's some guidance that is a bit warmer than the current forecast--so that record has a chance of being broken. The record high of 89 on the 18th (set in 2016 as well) is more of an outlier, so no real chance of threatening that record and the current forecast of highs well into the 70s is very sensible--especially considering the chance that the flow could already be shifting to cooler onshore flow on Sunday.

19

AVIATION . North to northeast flow aloft will continue tonight and Tuesday with an upper ridge off the coast and an upper low over the Intermountain West. At the surface, northerly offshore flow will continue to with a trough near the coast. The air mass will be dry and stable. Prevailing winds generally out of the north through the period, increasing to 10 to 15 kts with gusts 20 to 25 kts late Tuesday morning through sunset.

KSEA . VFR through the period. Winds will continue to decrease over the next few hours and become more northeasterly overnight AOB 10 kts. Winds will increase to 10 to 15 kts with gusts 20 to 25 kts by late tomorrow morning and persisting through sunset.

Schneider/Pullin

MARINE . Offshore flow will prevail this week. There will be small craft advisory strength north to northwest winds for the Coastal Waters, Northern Inland Waters, and Puget Sound the next few days, mainly afternoon and evening hours. The northerly breezes will turn a bit more easterly Thursday through Saturday.
