* Central Idaho Dispatch Area weather impact summary (Zones 475
and 476)...
Showers and thunderstorms continued late into last night. The affected
area will continue to shift to the north today and should clear late
tonight. The cold front from Sunday will keep temperatures much cooler
today, but the clearing skies tonight will allow afternoon highs on
Tuesday to start a warming trend that continues through at least Thursday.
A trough approaching from the north will increase the wind Thursday
afternoon, and possibly bring showers and thunderstorms for the coming
weekend.
* East Idaho Dispatch Area weather impact summary (Zones 410...411
and 413)...
Showers and thunderstorms continued late into last night. The affected
area will continue to shift to the north today and may linger along the
Montana border until Tuesday evening. The cold front from Sunday will
keep temperatures much cooler today, but the generally clearing skies
will allow afternoon highs on Tuesday to start a warming trend that
continues through at least Thursday. A trough approaching from the north
will increase the wind Thursday afternoon, and possibly bring showers
and thunderstorms for the coming weekend.
* South Central Idaho Dispatch Area weather impact summary (Zones
422...425 and 427)...
Showers and thunderstorms have cleared the region, although the extreme
end of the Sawtooth NF may see some isolated showers and thunderstorms
this afternoon, north of Galena Summit. Temperatures this afternoon will
be much cooler than last weekend temperatures. Warming and drying develop
starting Tuesday, and this trend should continue through Thursday. Cooling
returns Friday as a low moves in from the north. How far south it can spread
showers and thunderstorms remains to be seen, especially outside of the
northern portions of the Sawtooth NF. Gusty wind Thursday afternoon may see
the return of critical fire weather conditions on the eastern Magic Valley.
