.Drier northwest flow aloft will moderate temps thru the weekend.
The next chance for precip comes Mon aftn/eve as the eastern
Pacific ridge moves to the Rockies. This allows some moistur to
flow over the ridge...resulting in isolated tstms over the central
mtns. The tstm threat spreads to the Divide on Tue...then east out
of the area on Wed. The presence of the upper ridge will also push
temps back up Mon and Tue. Hedges


.AVIATION...High pressure will rebuild into southern Idaho and
return nearly clear skies, unlimited visibility, but 15KT to 25KT
sustained winds during the afternoon and evening at the Snake River
plain airdromes. Messick


.FIRE WEATHER...An extended period of dry weather starts today. Dry
northwesterly airflow will continue to cool temperatures, but the
cool temperatures will be offset by this airmass being very dry.
Thus afternoon humidity staying in the teens. Windy to breezy today,
but lighter winds for much of the rest of the week. Messick
