SYNOPSIS
Cool upper level trough over Western Washington moving east Tuesday. Brief upper level ridge Tuesday night. Systems Wednesday night into Thursday and Friday night and Saturday could move south of the area. Another front arriving early next week.
SHORT TERM /TONIGHT THROUGH THURSDAY/
Satellite imagery shows upper level trough over Western Washington this afternoon. Doppler radar has numerous showers with the highest concentration over the Cascades and the lowest along the coast. Temperatures at 4 pm/23z were in the lower to mid 50s.
Upper level trough remaining over Western Washington tonight. Very cold air aloft with 500 mb temperatures in the -30 to -32C range.
Lifted index values in the +2 to -2 range. With some afternoon sunshine temperatures have risen above the convective temperatures which are in the lower 50s. Have left a chance of thunderstorms in the forecast for this evening. The thunderstorm threat will end quickly once the sun goes down. Scattered showers continuing overnight into Tuesday morning with the trough still in place. It will be another cool for the end of April morning Tuesday with lows in the mid 30s to lower 40s.
Upper level trough remaining over Western Washington Tuesday for a repeat of Monday's weather. Temperatures aloft slight warmer as the trough begins to move east in the afternoon. Have left the mention of thunderstorms out of the forecast Tuesday afternoon.
If the trough is a little slower to move east look for a chance of thunderstorms to get added to the Tuesday afternoon forecast.
Highs once again below normal, in the mid and upper 50s.
Trough moving off to the east Tuesday night with a weak upper level ridge moving over the area. Still a chance of showers Tuesday evening as the daytime heating comes to an end but by midnight the shower activity should be over. With the decreasing cloud cover the colder location early Wednesday morning will be near freezing. For the remainder of the area lows in the mid 30s to lower 40s.
Wednesday looks to be the dry day of the short term with Western Washington in between systems. Upper level ridge will shift east during the day but the next system will just be crossing 130W at 00z Thursday. Temperatures aloft still a little cool but with some sunshine high temperatures "warming" to the mid 50s to lower 60s.
Models in good agreement with the next system tracking south of the area. The question is how far north with the rain associated with the system extend. Will keep pops in the chance category with likely pops along the coast. Increasing cloud cover will make lows a little warmer, in the lower to mid 40s.
System continuing to move southeast Thursday with a weak upper level trough over Western Washington. With the trough overhead will keep some chance pops in the forecast for most of the area.
Good chance the Northwest Interior and the San Juans are dry.
Highs Thursday near 60.
LONG TERM /FRIDAY THROUGH MONDAY/
Model solutions remaining inconsistent for most of the extended period. There is a general agreement that a cold upper level low will develop offshore Friday night. The ECMWF tracks this low into Oregon Saturday, close enough for at least showers over Western Washington. The GFS track is further west which would limit the precipitation chances to the coast. The ECMWF keeps the low over Oregon Saturday night into Sunday while the GFS has the low well south of the area.
Ensemble solutions mostly support the operational runs. There is better agreement with a splitting system arriving Sunday night into Monday. With the lack of consistency will have to go with chance pops for most of the extended period. Pops a little higher, in the likely category, with better agreement Monday.
Temperatures remaining below normal through the period with highs in the mid 50s to lower 60s and lows in the 40s. Felton
AVIATION
W/NW flow aloft as a transient ridge tracks overhead.
However, we'll see a brief switch to SW flow as a shortwave enters before more northerly flow develops into Tuesday. VFR across area terminals this afternoon with scattered showers. Convergence zone activity will persist this evening. Hi-res ensemble guidance has the bulk of the zone over KPAE before fizzling out late tonight. MVFR CIGs are at play again late tonight into early Tuesday morning, mainly for Puget Sound terminals. Any lingering low stratus should burn off to VFR conditions by midday Tuesday. W/SW winds 5-10 kts for most terminals this afternoon becoming lighter overnight.
KSEA...VFR so far this afternoon with scattered showers. SW surface winds between 5-10 kt will trend more towards the S around 10-12z Tuesday. MVFR is set to return late overnight (after 07z) before a rebound to VFR around midday Tuesday with a switch to northerly surface winds between 5-10 kt.

MARINE
SCA remain in effect over the central and eastern strait until tonight. Afterwards, a brief beak looks to set up but an additional SCA over the same zones is likely needed for Tuesday evening through Wednesday morning. A series of frontal systems will make their way into the region Wednesday night into Thursday followed by another one Friday night into Saturday. Will continue to monitor them if additional headlines are needed.
Seas 7 to 9 feet, then rising near 10 feet briefly into Tuesday as the next weak surface low enters. Seas then look to subside to 3 to 6 feet Wednesday onward.

HYDROLOGY
River flooding not expected in the next 7 days.
