...BREEZY THIS AFTERNOON AND EVENING...
...DRY WEATHER WITH WARMING TEMPERATURES THROUGH FRIDAY...

.DISCUSSION...
A low pressure system along the Idaho-Montana border will be
responsible for cooler and breezy weather today. Cumulus buildups
could bring a sprinkle to the burn site this afternoon, but
measurable precipitation is not expected. Winds will be strongest
this afternoon through tonight as the low pressure system increases
northerly flow. Dry weather will persist through the end of the
week and temperatures will gradually warm as the low exits eastward.
Winds will relax Thursday and Friday.
