Area Forecast Discussion National Weather Service Seattle WA 931 AM PDT Tue Apr 30 2024

SYNOPSIS
Shower activity will continue through the evening tonight before shifting southward. Conditions will be drier and warmer Wednesday through Friday, with cooler and wetter weather returning by the weekend.

UPDATE
A low pressure system will track through SW WA and NW OR today brining with it showers and a 15-20% chance of thunderstorms, mainly south of Seattle. Higher chances will exist as you move closer to Portland. Any storms could produce small hail, brief heavy rain, and lightning. The other concern we are monitoring is the potential for areas of frost by Wednesday morning, especially away from the metro areas and the coast where overnight lows will fall to 33-36 degrees. A Frost Advisory has been issued for these areas for tonight. Otherwise, the forecast is on track and no additional updates are planned this morning.

SHORT TERM /TODAY THROUGH THURSDAY/
A surface low will continue to push onshore through the morning and slide eastward throughout the day as an upper trough axis shifts over the Pacific Northwest.
Scattered showers will continue to stream eastward through the morning hours, slowly shifting southward through the afternoon as high pressure builds inland behind. The core of the surface low will track onshore along the Columbia Gorge today, enhancing instability with ensembles showing an average of 200-300 J/kg this afternoon mainly south and west of Seattle. Lightning and graupel cannot be ruled out of any stronger showers that develop in the afternoon. Precipitation will taper off by the evening, with temperatures staying on the cool side peaking in the mid 50s across the lowlands.

Weak ridging will allow conditions to dry out late Tuesday, and decreasing cloud cover overnight into Wednesday morning will allow some locations to see temperatures bottom out near freezing.
Otherwise, dry conditions will prevail for much of the day Wednesday with highs warming up to the upper 50s and lower 60s.

Another weak low pressure system will pass over the region late Wednesday into Thursday, with some uncertainty remaining over the exact track of the storm system. While most models bring this system south of the area, a chance of precipitation is maintained for much of the area through Thursday, favoring higher terrain.
Snow levels will hover near 3500-4000 ft with light precipitation amounts, and temperatures will continue a warming trend increasing into the low to mid 60s.

LONG TERM /FRIDAY THROUGH MONDAY/
Weak ridging will expand inland late Tuesday through Friday morning, with the potential for some areas to approach 70 degrees by Friday afternoon. A low pressure system is on track to move towards the Pacific Northwest by next weekend, but forecast models show fairly large differences in terms of placement and timing of any precipitation with this system. While uncertainty remains through the weekend, ensembles favor a cooler and wetter troughing pattern through Monday with a return to near-normal or slightly cooler temperatures.

MARINE
A weak surface low will traverse the coastal waters today and push inland along the WA/OR border by late morning/early afternoon. Seas briefly around 10 feet over the outer coastal waters with small craft advisory today. May see another low-end advisory strength push of westerly winds through the Strait tonight into early Wednesday, with probabilities highlighting a 50-60 percent chance of gusts occasionally exceeding 21 kt. Have held off of small craft issuance for now, however this will continue to be monitored through the day.

High pressure will build back into the area waters tonight into Wednesday, before yet another low and its associated frontal system move into the region Wednesday night into Thursday. The period will remain active, with another frontal system expected to traverse the area waters Friday night into the weekend.
