Dry westerly flow will continue across Idaho today for sunny skies and slightly below normal temperatures.

Over Utah and the AZ Strip southerly moisture remains in place across the south and east. Isolated thunderstorms will develop again this afternoon, mainly over the higher terrain.

Temperatures will gradually warm through the weekend region wide as the ridge strengthens over the Great Basin. Max temperatures will be back to the upper 90's by Sunday.

Thunderstorms continue over southern and central Utah on Saturday before the moisture moves further northward into northern Utah and southern Utah on Sunday. The storms across the north may be on the dry side, while the deeper moisture remains over southern Utah.

This thunderstorm activity will continue into the first part of next week, before slightly drier air may return to western Utah.

Fuels/Fire Potential
After a hot, dry weekend a return of thunderstorms to the north will likely result in new fire activity on Sunday/Monday.

Recent fire activity across northern and central Utah shows the current dryness of the fuels and the elevated potential for large fire growth. This potential should be decreasing by the first part of next week as deeper moisture moves into the state.

The up coming dry weather across the north will allow fire danger indices to return to above normal by early next week.

Fire danger indices remain near normal over Utah.
