HEAT WARNING: Another hot and humid day with temperatures approaching 100 degrees in Brooklyn; possible thunderstorms on the way | Northwest and national news

...HOT, DRY AND UNSTABLE ALONG WITH BREEZY WINDS THROUGH THURSDAY...

The high pressure driving this ongoing heat wave will begin to
weaken today, but will result in breezy and unstable conditions
through at least Thursday. Even as temperatures cool down slightly
over the coming days, relative humidities will remain very low in
the teens and single digits. This, combined with incoming breezy
conditions through the Cascade Gaps and spreading into the Basin,
will result in critical fire weather conditions.

Oregon and 691 Lower Columbia Basin.

* WINDS...West 12 to 20 mph with gusts up to 30 mph.

* IMPACTS...Breezy conditions combined with low RHs will result
in rapid fire spread and extreme fire behavior.

are either occurring now, or will shortly. A combination of
strong winds, low relative humidity, and warm temperatures can
contribute to extreme fire behavior.
