SYNOPSIS. Rain and thunderstorms are diminishing over western Washington this evening after an active afternoon. Drier and warmer conditions are expected tomorrow and into Tuesday before another system brings showers and cooler temperatures on Wednesday. High pressure will return and bring dry and mild conditions toward the end of the week.

SHORT TERM /TONIGHT THROUGH WEDNESDAY/. Most of the shower and thunderstorm activity should be winding down for the overnight hours. There are a few residual heavy showers in Snohomish county and over the Cascades at this hour, but those should be losing steam over the next few hours. The rest of the discussion from this afternoon is valid and will be posted below, as well as an updated aviation and marine discussion.

A weak warm front will clip southern B.C on Monday with a slight chance of rain near the Canadian border. Otherwise expect dry and slightly warmer weather elsewhere with temperatures in the 60s to lower 70s. Tuesday will be sunny and warmer with high pressure over the region. Temperatures will reach the upper 60s to mid 70s.

The next round of rain is on Wednesday as a short wave trough clips through the area. This is a quick moving system with just light rain totals expected (trace to a few hundredths if anything). 33

LONG TERM /THURSDAY THROUGH SUNDAY/. A broad area of high pressure will bring more dry and mild weather to western WA on Thursday and Friday. The flow aloft turns more zonal over the weekend with a weak frontal system splitting as it reaches the coastal waters, with light rainfall amounts possible (mainly at the coast). High pressure then rebuilds over the area early next week for another dry and mild period of weather. 33
