It’s overcast and cool today, but the National Weather Service reports that’s about to change.

From the National Weather Service:

Strong high pressure continues throughout the remainder of the week, providing warm and dry conditions to most of the area.

A more significant warm up arrives late this weekend across most of the area, where high temperatures rise into the mid to upper 70s on Saturday and Sunday in the Harbor.

Elevated fire weather conditions are likely due to warm and prolonged dry conditions of both the fuels and expectation of low relative humidity. Expect minimum relative humidity values to be between 20 and 30% in Cascade Valleys and along the ridges.

Overnight temperatures will be the warmest on Saturday and Sunday nights, in the upper 50s. This will limit the overnight relief from the heat for those without adequate cooling, or who rely on opening windows during the night hours.

The duration of this level of heat will be relatively short, with Sunday likely being the warmest day over the next week. Temperatures will gradually cool down into the beginning of next week, although some uncertainty exists as to how quickly temperatures cool, especially for the interior.
