AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
232 PM MDT SUN AUG 3 2025
SYNOPSIS
A HOT AND VERY DRY PATTERN WILL SET UP ACROSS THE
REGION THROUGH MUCH OF THE NEXT WEEK. A DRY COLD FRONT MAY BRING
SOME RELIEF BY NEXT WEEKEND.
SHORT TERM (THROUGH 12Z TUESDAY)
AS THE SHORTWAVE RIDGE SHIFTS
EASTWARD, DEEP SOUTHWEST FLOW WILL DEVELOP ACROSS UTAH IN A
CLASSIC FIRE WEATHER PATTERN. THIS WILL BRING HOT AND VERY DRY
CONDITIONS TO THE BEEHIVE STATE THROUGH THE SHORT TERM FORECAST
PERIOD AND INTO THE LONG TERM FORECAST PERIOD. RED FLAG WARNINGS
ARE NOW IN EFFECT FOR MUCH OF THE STATE MONDAY, WITH PORTIONS OF
CENTRAL AND SOUTHERN UTAH CONTINUING INTO WEDNESDAY. FOR MORE
INFORMATION ON THE FIRE WEATHER ISSUES, PLEASE SEE THE FIRE
WEATHER DISCUSSION.
EXPECT TEMPERATURES TO INCREASE A FEW DEGREES ACROSS THE STATE
BETWEEN SUNDAY AND MONDAY.
LONG TERM (AFTER 12Z TUESDAY), ISSUED 351 AM MDT
A BROAD
RIDGE OVER THE SOUTHWESTERN US IS EXPECTED TO STRENGTHEN AND
BECOME CENTERED OVER NEW MEXICO ON TUESDAY. UTAH AND SOUTHWEST
WYOMING WILL REMAIN WEDGED BETWEEN THIS FEATURE AND A LONGWAVE
TROUGH OVER THE PACIFIC NORTHWEST THROUGH FRIDAY, KEEPING THE
PATTERN GENERALLY STAGNANT THROUGH THIS PERIOD. WEAK MID-LEVEL
MOISTURE TRANSPORT ALONG THE WESTERN PERIPHERY OF THE RIDGE WILL
SUPPORT DAILY AFTERNOON SHOWER AND THUNDERSTORM CHANCES WEDNESDAY
THROUGH FRIDAY, MAINLY ACROSS SOUTH-CENTRAL AND SOUTHEASTERN UTAH.
HOWEVER, GIVEN THE STRENGTH OF THE RIDGE AND VERY DRY LOWER-
LEVELS ALREADY IN PLACE, ANY STORMS THAT DEVELOP WILL BE DRY IN
NATURE, WITH MAIN THREATS FOR GUSTY AND ERRATIC OUTFLOW WINDS.
ENSEMBLE CLUSTERS SUPPORT A SHORTWAVE TROUGH DROPPING INTO THE
NORTHERN INTERMOUNTAIN REGION SATURDAY, WHICH MAY PROVIDE ENOUGH
INSTABILITY FOR MORE WIDESPREAD AFTERNOON CONVECTION ON SATURDAY.
WITH LITTLE MOISTURE IN PLACE, HOWEVER, THE MAIN THREAT REMAINS THE
POTENTIAL FOR DRY MICROBURSTS.
AVIATION...KSLC
VFR CONDITIONS WILL PERSIST FOR THE KSLC TERMINAL
THROUGH THE PERIOD. CLEAR SKIES AND DRY CONDITIONS WILL CONTINUE AS
LIGHT NORTHERLY WINDS TRANSITION TO LIGHT SOUTHERLY WINDS OVERNIGHT.
REST OF UTAH AND SOUTHWEST WYOMING
VFR CONDITIONS WILL PERSIST
FOR THE ENTIRE AIRSPACE THROUGH THE PERIOD. MOSTLY CLEAR SKIES AND
DRY CONDITIONS WILL CONTINUE AS WINDS REMAIN RELATIVELY LIGHT AND
DIURNALLY DRIVEN.
FIRE WEATHER
AS DEEP SOUTHWEST FLOW BUILDS INTO THE REGION, A
LONG DURATION PERIOD OF CRITICAL FIRE WEATHER CONDITIONS WILL
IMPACT UTAH. SINGLE DIGIT HUMIDITIES AND GUSTY WINDS WILL BRING
WIDESPREAD CRITICAL FIRE WEATHER CONDITIONS MONDAY. AFTER A VERY
POOR OVERNIGHT RECOVERY, GUSTY WINDS WILL DEVELOP ACROSS CENTRAL
AND SOUTHERN UTAH TUESDAY ONCE MORE. BY LATER TUESDAY INTO
WEDNESDAY, MID-LEVEL MOISTURE WILL BEGIN TO INCREASE ACROSS
SOUTHERN UTAH. WHILE LITTLE TO NO THREAT OF PRECIPITATION IS
EXPECTED WITH THIS MOISTURE INCREASE, IT MAY BE ENOUGH TO BRING
MINIMUM HUMIDITIES ABOVE 15% FOR THE CENTRAL AND SOUTHERN
MOUNTAINS. CRITICAL FIRE WEATHER CONDITIONS LOOK TO CONTINUE FOR
THE VALLEYS THROUGH AT LEAST FRIDAY. A DRY COLD FRONT MAY CROSS
INTO THE REGION SATURDAY, BRINGING SOME RELIEF TO THE LOW
HUMIDITIES.
