Area Forecast Discussion National Weather Service Seattle WA 344 AM PDT Sun May 5 2024

SYNOPSIS
Cool and unsettled conditions continue across the region early this week. A shift in the pattern toward midweek with bring about dry conditions and steadily warming temperatures through the second half of the week.

SHORT TERM /TODAY THROUGH TUESDAY/
A mild start to the day across the region with temperatures generally in the lower 50s at this hour and rather damp with low stratus or fog present through the interior this morning. Shower activity has diminished a bit as the low begins to drift away, but some moisture does continue to wrap around and move across the southern portions of the area (generally from Olympia southward). Expect some showers to continue this morning with an increase later in the day as stronger onshore flow develops as the next trough approaches.
Expect primarily rain through the interior, though some light snow will be possible above around 4500 feet and especially in the higher Cascade elevations.

A stronger upper level trough approaches and moves into the region on Monday. As cooler air aloft pushes into the region, steepening lapse rates will increase the potential for isolated thunderstorms through the day on Monday. Strong onshore flow will develop with a Puget Sound Convergence Zone likely to develop into the afternoon and evening. While snow levels will dip a bit closer to the Cascade passes, the most significant threat for strong showers will be under the PSCZ, especially if it's able to push into the mountains.

LONG TERM /WEDNESDAY THROUGH SATURDAY/
Ensemble guidance continues to depict high confidence in a shift to a much warmer pattern through the second half of the week as a strong ridge builds over the western U.S. starting around midweek. Still some variations evident in the clusters of ensemble members with respect to where the ridge axis sets up and just how strong it is, but confidence is high in seeing temperatures climb to at least 10 to 15 degrees above normal by the late stages of the week for much of the lowlands. Current forecast from the NBM suggest a run into the lower to mid 80s is possible for the warmest spots Saturday. While the precise temperature forecast will fluctuate a bit in the coming days, it's worth noting that this will be a significant warm up and coupled with the calendar turning to May, many folks may be out around area water. Keep in mind that local waters are still quite cool and be sure to adhere to safety practices if you're out in or around the water later this week.
