SHORT-TERM FORECAST
We have one more wave of clouds and moisture to get through today, but any precipitation will be light and scattered. Thereafter, higher pressure will move overhead and persist into the upcoming weekend. Expect a warming trend, with temperatures expected to rise into the 70s, giving us some pleasant late summer-like weather. Even so, I can't totally rule out the chance of an isolated shower as weak disturbances continue to pass close to the forecast area at times, especially later in the week.
LONG-TERM FORECAST
Dry and warm weather looks to continue into the early part of the extended period before high pressure begins to weaken. Once that happens, storminess will once again pass close to the Northwest. That should lead to a renewed chance of showers and at the very least, another cooling trend as next week progresses.
General Short-Term Model Agreement: GOOD
