SYNOPSIS
Cool and unsettled conditions through Tuesday with a frontal system set to slowly move across western Washington tonight into Monday morning. A pattern shift still on as we head into the second half of the week with strong high pressure building across the Pacific Northwest, bringing steadily warming and dry conditions through next weekend.

SHORT TERM /TONIGHT THROUGH WEDNESDAY/
Damp conditions continue this afternoon with a band of more noticeable rainfall associated with weak Puget Sound Convergence Zone enhancement across southern Snohomish into central King County and the Cascades.
Surface temperatures remain above freezing at the passes this afternoon with just wet roadways as per traffic cams. Current temperatures in the upper 40s to lower 50s with little variation across much of western Washington. Breezy south-southwesterly winds through tonight ahead of an incoming cold front.

This front will move onshore late tonight, with precipitation coverage increasing along with southwest winds this evening. Lows not falling a whole lot once again tonight into the low to mid 40s. Snow levels gradually begin to drop from around 5000 feet closer to 4000 feet into Monday morning.

An upper-level trough will dig southward across the Pacific Northwest Monday in the wake of the passing surface low and weak cold front. This will bring the chance for convective showers and thunderstorms thanks to steep low-level lapse rates as anomalously cold air aloft moves just overhead and 500 mb heights approach -30C. Brief gusty winds and small hail along with isolated lightning will all be possible, especially with the development of a Puget Sound Convergence Zone across Snohomish into central Skagit County by late morning, slowly drifting southward into King County by the evening. With fairly deep moisture, expect isolated lightning and small hail to be the primary convective hazards.
Cannot rule out another round of showers and perhaps a lightning strike or two on Tuesday, though less instability as the main upper-level trough shifts off to our east. High temperatures nearly 10 degrees below normal Monday in the low to mid 50s, rising into the upper 50s Tuesday.

Light to moderate snowfall is expected across the Cascades as snow levels drop through the day Monday to below 3000 feet by early Tuesday morning, perhaps down to 2700 feet, which will allow for light snowfall accumulations late Monday through Tuesday and Tuesday night. Snowfall ratios will stay mostly below 10:1 Monday, largely mitigating snowfall accumulation at the Cascade passes, but greatest concern will be for convergence zone enhancement of snowfall rates into Monday night, where snowfall would be the most likely to accumulate on roadways above 2700 feet. At this time, total snowfall Monday through Tuesday looks to remain below advisory thresholds, with a 60% chance for at least 4 inches of snow through 5 pm Tuesday at Stevens Pass and 20% at Snoqualmie Pass. Chances for at least 6 inches drops much more to around 25% and 5%, respectively. Though this will be a late-season snow, Winter Storm Severity Index forecasts generally less than a 50% chance for only minor travel disruptions, furthering the decision to hold off on any Winter Weather Advisories at this time. Will need to monitor exactly how convergence banding sets up and for how long across the passes late Monday into Tuesday, however.

Heading into Wednesday, a pattern change begins with upper-level ridging and surface high pressure building across the Pacific Northwest. High temperatures nudge upward into the upper 50s to lower 60s with partly cloudy skies.

LONG TERM /THURSDAY THROUGH SUNDAY/
Little change in the forecast into the second half of the week as long range ensemble guidance develops a Rex Block across the West with strong ridging across the Pacific Northwest Thursday through Saturday north of an upper low that cuts off across California and Nevada. This low and block begin to disintegrate by Sunday with the ridge deamplifying. A thermal trough also looks to develop along the coast Thursday and Friday, helping to promote offshore flow and weak downslope warming. Ensemble guidance continues to hone in on Saturday for the warmest high temperatures, though the NBM indicates a nearly 60% chance for highs above 80 on both Friday and Saturday for most of the lowlands aside from areas along waterfronts. The warmest temperatures appear most likely across the Southwest Interior with over a 90% chance for highs over 80 Friday and Saturday. Though the high temperature forecast is likely to fluctuate to some extent in the coming days, this looks to be are first run at 80 degrees for many. Keep in mind that local waters remain very cold, with hypothermia risk possible even with these warm air temperatures. Adhere to safety practices if planning time outdoors near any bodies of water late this week and weekend.

AVIATION
Light flow aloft becoming westerly as a frontal system moves down from the Gulf of Alaska. Conditions have improved this afternoon to mostly MVFR throughout most interior terminals, and VFR at coastal terminals (KCLM and KBLI). MVFR conditions will most likely continue into the evening and overnight for all terminals as shower coverage increases into Monday morning. As shower coverage increases in the interior, there is a 20% chance of brief lower visibility's and ceilings down to IFR into Monday 12z. Expect conditions to gradually improve by 20z Monday to mostly VFR through interior terminals.

Breezy S/SW winds this afternoon around 12 to 17 kts will continue into the evening.. with gusts possible up to 25 kts.
Winds will start to ease by late Monday afternoon.

KSEA...MVFR conditions this afternoon will continue into the overnight as showers move through the area. Breezy S/SW winds this evening around 13 to 16 knots with potential gusts up to 20 to 25 kts into the night. MVFR restrictions will start to lift up to a VFR potentially by 19-22z Monday. Winds will start to ease by late Monday afternoon.

Mazurkiewicz

MARINE
A frontal system will move through the area waters late tonight into Monday, with increasing onshore flow along with it.
Small craft advisory strength southwesterly winds will continue for the Central and Eastern Entrance of the Strait through tonight. Winds in the Eastern Strait will subside tonight but will increase again up to small craft strength by Monday afternoon.

Small craft southerlies will also continue through the Puget Sound and Hood Canal areas until Monday afternoon. At this time, winds in the Northern Inland Waters look to remain below any thresholds, staying around 10 to 20 kts - along with winds on the coastal waters, although cannot rule out a gust or two of small craft advisory strength.

High pressure looks to build offshore beginning Tuesday night into Wednesday for more calmer and benign marine conditions.

Combined seas around 6 to 8 feet will slowly build up to near 10 feet by Monday night and will remain 10 feet into Tuesday. Seas will subside to around 5 to 7 feet into Wednesday.
