* Central Idaho Dispatch Area weather impact summary (Zones 475
and 476)...
The cold front from Sunday will keep temperatures much cooler
today, but the 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.
* East Idaho Dispatch Area weather impact summary (Zones 410...411
and 413)...
The cold front from Sunday will keep temperatures much cooler
today, but the 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)...
Temperatures this afternoon will be much cooler behind the cold
front. 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
to the eastern Magic Valley.
