FIRE WEATHER PLANNING FORECAST FOR UTAH
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
248 AM MDT THU SEP 18 2025
..MOISTURE INCREASING TONIGHT INTO THE WEEKEND
BROADCAST DISCUSSION
DRY AND WARMER CONDITIONS SETTLE IN
TODAY BEFORE MOISTURE RETURNS FROM THE SOUTH TONIGHT INTO THE
WEEKEND INCREASING CHANCES FOR SHOWERS AND THUNDERSTORMS. DRY
LIGHTNING WILL BE POSSIBLE INITIALLY, WITH WETTING RAIN CHANCES
INCREASING ESPECIALLY OVER SOUTHERN UT THROUGH THE DAY FRIDAY.
DISCUSSION
HIGH PRESSURE OVER THE AREA TODAY WILL RESULT IN
WARMER AND DRY CONDITIONS ACROSS THE AREA. AS THIS HIGH PRESSURE
MOVES EAST OF THE AREA, SOUTH TO SOUTHWEST FLOW WILL DRAW MOISTURE
INTO THE AREA BEGINNING TONIGHT AND INTO THE WEEKEND. EXPECT
SHOWERS AND THUNDERSTORMS TO BE POSSIBLE ACROSS SOUTHWEST UTAH
TONIGHT, SPREADING INTO CENTRAL AND POTENTIALLY PORTIONS OF
NORTHERN UTAH DURING THE DAY FRIDAY. SHOWERS NEAR THE LEADING EDGE
OF THE MOISTURE SURGE WILL MORE LIKELY RESULT IN ISOLATED DRY
LIGHTNING AND GUSTY MICROBURST WINDS. WITH SURFACE HUMIDITIES
INCREASING, WETTING RAIN CHANCES WILL GRADUALLY INCREASE THROUGH
THE DAY. BY SATURDAY AND SUNDAY, PRECIPITATION CHANCES WILL BECOME
INCREASINGLY FOCUSED OVER NORTHERN UTAH. DRIER AIR WILL THEN
SPREAD BACK INTO UTAH EARLY NEXT WEEK. ANOTHER ROUND OF MOISTURE
WILL BE POSSIBLE BY THE MIDDLE OF NEXT WEEK, BUT WITH SIGNIFICANT
MODEL SPREAD, CONFIDENCE REMAINS ON THE LOW SIDE FOR NOW.
***THUNDERSTORMS IMPLY STRONG, GUSTY AND ERRATIC WINDS***
***ALL WINDS ARE 20 FOOT, 10-MINUTE AVERAGES***
