Weather
Generally warm and dry conditions will continue today and Wednesday across much of the region. Isolated thunderstorms are possible today over some of the higher terrain across the region. Relative Humidity will be quite low today with mins in the teens overs western Idaho.

Moisture from Hurricane Odile begins to move into the AZ Strip and southwest Utah on Wednesday for increasing cloud cover, cooler temperatures and showers. These storms will continue across western Utah on Thursday and overnight Thursday into Friday morning across northern Utah and southeast Idaho.

This moisture is being drawn northward by a trough moving into the western U.S. which will increase the chance for showers over central and eastern Idaho and western Wyoming for Thursday into Friday as well.

By late Friday through the weekend drier air will return to the region for gradually warming temperatures. Max temps should be back in the low to mid 80's in Boise and SLC by Sunday.

The longer term forecast calls for a return to warm and dry conditions across the north for the last 10 days of the month.

Fuels/Fire Potential
Warm temperatures and low relative humidity over the next few days will keep fire potential somewhat elevated for the time of year, but large fire potential remains fairly low.


Fire potential will decrease rapidly by Wednesday/Thursday as showers move into the region.
