SYNOPSIS
Weakening front dissipating over Western Washington this evening. Next system moving over Western Washington and stalling Thursday before moving east Thursday night. Cool upper level trough over the area Friday. Another weather system arriving Saturday. Upper level trough over the area Sunday into the middle of next week keeping temperatures below normal into the first part of May.
SHORT TERM /TONIGHT THROUGH SATURDAY/
Satellite imagery and doppler radar show slow moving narrow front on a line from about Everett to Elma to Astoria. Rain with the front is light with just a couple hundredths at Everett this afternoon. Cloudy skies outside of the front. Temperatures much cooler than Tuesday with lower to mid 50s at 3 pm/22z.
Front will continue to move slowly east eventually dissipating over the Cascades later this evening. Not much rain left with the front with less than a tenth of an inch possible. A little break behind the front late tonight into early Thursday morning with the next system currently just east of 140W. Cloudy skies overnight will keep lows in the mid to upper 40s.
Rain ahead of the next system moving into Western Washington Thursday morning. Weak jet associated with the front digging south into Oregon Thursday afternoon. This will cause the front to stretch out, weaken and become stationary over Western Washington making for a wet late April day. Rain most of the day will make for little in the way of daytime heating with the high temperatures only a few degrees above the lows, in the lower to mid 50s.
As the jet continues to dig south front dissipating over Western Washington late Thursday night into Friday morning. Daily rainfall records are on the low side Thursday. For example, the record rainfall for Seattle is 0.59 inches set in 2020. There is a chance some daily rainfall records could be broken, not so much from heavy rain just steady rain all day Thursday. Seattle April monthly rain total currently at 0.43 inches so there is a chance Seattle gets more rain Thursday than the previous 24 days in April. Steady rain giving way to more showery precipitation with the front dissipating early Friday morning. Lows once again in the mid to upper 40s.
Cool upper level trough hanging out over the area Friday. Jet well to the south with little dynamics overhead but cooler air mass aloft enough to keep showers in the forecast. It will be another below normal day temperature wise with highs in the mid to upper 50s.
Upper level trough shifting east Friday night with showers coming to an end. Next system reaching Western Washington during the day Saturday with rain spreading back over the area. Parent low for the front in the Northern Gulf of Alaska so this will not be a strong system with rainfall amounts mostly under a tenth of an inch. Lows Friday night in the 40s with highs Saturday in the mid to upper 50s.
LONG TERM /SUNDAY THROUGH WEDNESDAY/
Extended models remaining consistent in the idea of a cool upper level trough over Western Washington Sunday and Monday. Snow levels dropping down to near 3000 feet Monday bringing up the possibility of light snow on all the passes. Some differences in the models show up beginning Tuesday. There is good agreement that a closed low will form in the trough Tuesday but the location of this feature is much different with the GFS taking the low well offshore Wednesday while the ECMWF has the low much closer to the coast. Even with the different locations of the upper level low both solutions keep showers over Western Washington Tuesday and Wednesday along with a continuation of below normal temperatures. It's going to be a cool last week of April for Western Washington. Felton
AVIATION
W to SW winds aloft with a broad upper-level trough to the north. A mixed bag of ceilings across the area ranging from VFR to IFR as scattered showers slowly work their way across the region.
Winds a bit breezy through the central Puget Sound (PWT, SEA, BLI)
but otherwise light south/southwesterly.
Expect CIGs to generally remain low-end VFR to high-end MVFR through around 06Z Thursday when the next frontal system will usher in more consistent MVFR to IFR cigs that should persist through most of tomorrow. Visibility restrictions due to heavy rain is possible, especially along the coast. Winds will ease tonight, then build back to more S 8-12kt with gusts up to 20kt possible.
KSEA...Low end VFR to occasional MVFR should persist through early evening. Solidly MVFR conditions after 06Z Thursday with rain coming in after 12Z. Limited visibility possible in heavy rain. SW winds 10- 15 kt decreasing to 4-8 kt tonight, then backing to S 8-12 kt with gusts up to 20kt possible tomorrow.
LH
MARINE
Scattered showers continue across the coastal waters in the wake of a dissipated front. A more substantial system will move through the area waters on Thursday. A more substantial frontal system will move into the area early tomorrow. Southerly winds will increase throughout the coastal waters, but the areas with the best chance to see Small Craft Advisory conditions will be in waters south of Point Grenville (50-85% probability, especially within 20 NM of shore). As such, a Small Craft Advisory is effect for Thursday. Additionally, rain will be heavy at times, which will likely reduce visibilities as low as 1-3NM during the heaviest rain.
Breezy conditions will continue on Friday for the outermost coastal waters as the low pressure center moves through western Washington.
A weak surface ridge will calm things down on Saturday before another front moves through the region Sunday. The active pattern looks to continue into the beginning of next week.
Seas look to remain 4 to 6 feet at about 10 seconds through the rest of the week and into Saturday. Seas look to rise to 8 to 10 ft beginning Sunday.
LH
HYDROLOGY
No river flooding expected in the next 7 days.
Heavier rain over the south slopes of the Olympics Thursday into Thursday night could push the Skokomish River in Mason county close to action stage Friday. Felton
SEW WATCHES/WARNINGS/ADVISORIES
WA...None.
PZ...Small Craft Advisory from 5 AM to 5 PM PDT Thursday for Coastal Waters From Point Grenville To Cape Shoalwater 10 To 60 Nm- Coastal Waters From Point Grenville To Cape Shoalwater Out 10 Nm.
