Fire Weather Planning Forecast for SW Idaho and SE Oregon
National Weather Service Boise ID
826 AM MDT Thu May 24 2018

...Showers and thunderstorms continue through the weekend...


.DISCUSSION...
An upper low that has been over the Great Basin the last few days
has finally lifted out of the area. This puts a brief upper ridge
over Idaho/Oregon area today. The airmass remains warm and moist,
therefore showers and thunderstorms remain in the forecast this
afternoon. Another upper low moves into the Sierras Mountains Friday and
Great Basin Friday night bringing much better chances of strong
thunderstorms some of which could bring heavy rains, hail, and strong
gusty winds to 50 mph in the afternoon and through Friday night. The upper
low will slowly drift into Utah by Sunday.
