.SHORT TERM...Today through Thursday.
Will have continued dry weather today and Wednesday with an upper
level trof and associated cold front moving through Idaho on
Thursday. Winds will be light today with very hot temperatures
once again today and Wednesday. Expect significant wind increase
with the frontal passage Thursday as well as isolated
thunderstorms mainly across the Upper Snake Highlands near the

Dry conditions are expected through the long term period with
possible breezy to windy conditions over the weekend on Sunday and
Monday. Temperatures may moderate a bit over the weekend but cool
down again next week but not expecting nearly the heat of this

a cold front passing through eastern Idaho.


Main impact today and Wednesday will be widespread Haines of 6

extremely hot and dry conditions.  On Thursday the main impact will
be much stronger winds as a cold front moves through Idaho and could
reach red flag conditions possibly in zone 410.   Isolated
thunderstorms may also occur Thursday mainly in zones 475, 476 and
411 although confidence very low in the thunderstorms.  Could see
breezy to winds conditions Saturday and Sunday as well as strong
