Area Forecast Discussion National Weather Service Seattle WA 305 PM PDT Wed Jun 5 2024

SYNOPSIS
High pressure builds over the region today, bringing a warming and drying trend to western Washington for the second half of the week. The warmest temperatures are expected Friday and Saturday. A weak shortwave moving across the area on Sunday may bring slightly cooler temperatures and some showers to the mountains. Temperatures then look to fall closer to normal by early next week.

SHORT TERM /TONIGHT THROUGH SATURDAY/
Decreasing cloud cover across the region this afternoon with areas of scattered clouds as temperatures warm. Temperatures are trending to near seasonal normals today with the decreasing clouds. High pressure will continue to build over the region through the second half of the week, which will lead to the air mass steadily warming during each of the next several days. At this point, Friday and Saturday look to be the warmest days with most likely temperatures landing in the lower 80s for the interior, roughly 10 or so degrees above normal. This would reflect most minor HeatRisk, with some pockets of moderate HeatRisk. While confidence remains high with this pattern, it does seem unlikely (less than 10% chance) of seeing temperature reaching daily record highs or warm enough to boost the expected HeatRisk into a higher category. Ensemble guidance continues to favor enough of a frontal system approaching by late Saturday to prevent a longer duration of building heat, which is another factor that will keep the HeatRisk from climbing higher.
That said, even with the warming air temperatures, it's important to note that local waterways remain cool so ensure that caution is taken around and near rivers and streams.

LONG TERM /SUNDAY THROUGH WEDNESDAY/
A weak disturbance will likely induce some increasing onshore flow as it passes into the Pacific Northwest around Sunday. This will bring a return of marine air in to the interior with some increasing cloud cover and slightly cooler temperatures. Some shower chances can't be ruled out in the higher terrain of the Olympics and Cascades, but significant rainfall is not expected. Ensemble guidance continues to favor a ridge developing over the western U.S. early next week which will generally bring warmer and drier conditions, but passing disturbances will maintain at least some chances for increased clouds and temperatures fluctuating back down closer to normal values at times.
