Area Forecast Discussion National Weather Service Seattle WA 929 AM PDT Tue Mar 31 2020

SHORT TERM /TODAY THROUGH THURSDAY/. The two main forecast concerns today into Wednesday will be continued snow showers across the mountains and relatively weak thunderstorm activity across the region.

As of 915 AM, radar indicates weakening convective showers over the Puget Sound region, with another push of shower activity pushing into the coastal areas that is associated with a 700mb vorticity lobe currently situated along the coast. These showers will continue to push inland today. Instability is expected to increase with widespread SBCAPE values of 100-500 J/kg and very little CIN. While any convection will be shallow, the prime hail growth zone will be very low, between 7000-15000 feet, and as such will result in a threat of copious small hail with stronger cells. Lightning will also be a concern. Shear will be minimal across all but the southern reaches of the CWA which will limit the threat of organized storms. Still, we will be monitoring the situation today.

With this convection, a PSCZ or at least some enhancement over the central Cascades cannot be completely ruled out, but also isn't unanimously forecast by high-res guidance. Since these convective showers can result in rapid snow accumulation, I did extend the Winter Weather Advisory through 12z Wednesday for the central and southern Cascades as well as the Olympics. The North Cascades may get a few more showers, but the threat there is diminishing rapidly and the Winter Storm Warning will be allowed to expire at 11 AM as scheduled. -Wolcott-

The upper trough shifts inland over on Oregon on Wednesday. There will enough instability to keep some showers and isolated thunderstorms around . especially across the southern half of the forecast area, but this activity should decrease pretty quickly by sundown. Another wrinkle in the northwest flow aloft might be enough to develop a few showers later on Thursday, but it doesn't like much in terms of QPF. 27

LONG TERM /FRIDAY THROUGH MONDAY/. Western Washington will likely be under the influence of large scale upper troughing through the extended forecast period. A broad upper trough sinking southward over British Columbia and Alberta on Friday is likely to generate more precipitation in particular across the interior of Western Washington. Confidence in the details for the upcoming weekend is rather low. Another upper trough is expected to dig southward offshore on Saturday then shift onshore Saturday night or Sunday. The weekend might start off dry, but finish rather wet. Despite timing issues, the ensemble means for both the GFS and Euro strongly support deep troughing continuing over the region for wet conditions and below average temperatures. 27

AVIATION. Unstable air mass remains in place with mix of broken MVFR/IFR ceilings and clearing skies, with fairly widespread showers across the region. As such, expect a similar pattern today as yesterday with a trend to predominantly VFR ceilings with temporary reductions in visibility/ceilings in heavier showers. Again a chance of an isolated thunderstorm this afternoon, but confidence and coverage again too low to for TAF inclusion. Winds generally southerly or southwesterly across the area at around 10 kt, but expect a shift to northeasterly winds across the north late tonight, impacting KBLI and KCLM.

KSEA . Ceilings MVFR gradually trending to low VFR later this morning. Meanwhile, scattered showers through the period could bring brief reductions at times this afternoon/evening, along with possibility of a thunderstorm. Otherwise, mostly VFR in the afternoon/evening, with ceilings lowering overnight back into the lower MVFR range. Winds generally S/SW around 10 kts through the period. Cullen

MARINE. Onshore flow continues across the waters today with relatively light surface gradients. A small craft advisory will remain in place for the coastal waters, the western Strait of Juan de Fuca, and Grays Harbor Bar due to elevated seas. Model guidance suggests seas remain the 9-12ft range into the overnight hours before easing closer to 7 feet into Wednesday.

A surface low with move south from near Haida Gwaii today through the coastal waters tonight. This will bring increasing winds on the NE side of the low across the northern inland waters and down the Strait of Juan de Fuca very early Wednesday to high-end small craft advisory level winds. These northerly winds also look to eventually make it into Admiralty Inlet, Puget Sound, and the portions of the northern Coastal Waters a little bit later in the day on Wednesday. Will need to monitor the potential for Gale Force winds across the Strait/N Inland Waters early Wednesday. Winds may then remain elevated into Thursday across the interior waters before finally relaxing through the remainder of the week. Seas look to remain benign with only a few small swells reaching the waters at times this week. Cullen

HYDROLOGY. An unsettled pattern will continue through the week ahead, but the progressive nature of the pattern and precipitation amounts are not expected to lead to flooding concerns.

SEW WATCHES/WARNINGS/ADVISORIES. WA . Winter Weather Advisory until 5 AM PDT Wednesday for Cascades of Pierce and Lewis Counties-Cascades of Snohomish and King Counties-Olympics.

Winter Storm Warning until 11 AM PDT this morning for Cascades of Whatcom and Skagit Counties.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
