DISCUSSION, ISSUED 158 PM MDT WED JUN 17 2026
OUR REGION REMAINS UNDER THE INFLUENCE OF A RIDGE
CENTERED TO OUR WEST AND LONGWAVE TROUGHING EAST OF THE ROCKIES.
THIS HAS YIELDED INCREASED NORTHWEST FLOW ESPECIALLY ACROSS EASTERN
PORTIONS OF UTAH, AND WHEN COMBINED WITH A VERY DRY AIRMASS IN
PLACE, WE CAN EXPECT CRITICAL FIRE WEATHER CONDITIONS TO CONTINUE
THROUGH THIS EVENING ACROSS THE AREA. WARMER, WESTERLY FLOW ACROSS
SOUTHERN UTAH WILL YIELD QUITE HOT CONDITIONS ESPECIALLY ACROSS
LOWER WASHINGTON COUNTY AND LAKE POWELL, WITH TEMPERATURES TOPPING
OUT AROUND 105. WIDESPREAD MODERATE AND LOCALLY MAJOR HEATRISK WILL
RESULT FROM THIS HEAT ACROSS SOUTHERN UTAH, SO THOSE SENSITIVE TO
HEAT SHOULD TAKE PRECAUTIONS TO AVOID HEAT-RELATED ILLNESS.
THE AFOREMENTIONED RIDGE WEAKENS AND SHIFTS EASTWARD OVERHEAD ON
THURSDAY, RESULTING IN LIGHTER WINDS ACROSS THE REGION. HOWEVER,
SOME BREEZY WINDS MAY CONTINUE ESPECIALLY ACROSS THE CENTRAL AND
SOUTHERN MOUNTAINS, LEADING TO ELEVATED TO MORE LOCALLY CRITICAL
FIRE WEATHER CONDITIONS.
THE BRIEF BREAK IN WIDESPREAD CRITICAL FIRE WEATHER CONDITIONS
WILL BE SHORT LIVES AS A SHORTWAVE TROUGH DEEPENING ACROSS THE
WEST COAST ON FRIDAY BRINGS INCREASING SOUTHWESTERLY FLOW ALOFT.
THIS PATTERN WILL BRING VERY HOT CONDITIONS AREAWIDE, ESPECIALLY
ACROSS NORTHERN AND EASTERN VALLEY LOCATIONS WHERE HIGHS WILL
APPROACH 100 DEGREES. GUSTY SOUTHWEST WINDS 30-40 MPH DEVELOP
THROUGH THE AFTERNOON ESPECIALLY ACROSS SOUTHWEST AND WEST-CENTRAL
UTAH THROUGH FRIDAY AFTERNOON, PEAKING DURING THE EVENING HOURS.
SLIGHT IMPROVEMENT IN OVERNIGHT HUMIDITY RECOVERIES IS EXPECTED
OVERNIGHT INTO SATURDAY MORNING ACROSS THE REGION, THOUGH REMAIN
QUITE POOR ACROSS PORTIONS OF CENTRAL AND EASTERN UTAH. THE GUSTY
WIND THREAT SHIFTS EASTWARD AND EASES SLIGHTLY ON SATURDAY AS THE
SHORTWAVE FLATTENS AND FLOW ALOFT BECOMES MORE ZONAL, THOUGH AREAS
OF CRITICAL FIRE WEATHER CONDITIONS MAY DEVELOP THROUGH THE
AFTERNOON ESPECIALLY ACROSS EASTERN UTAH WHERE FUELS ARE CRITICAL.
LOOKING INTO NEXT WEEK, RIDGING BECOMES THE DOMINANT FEATURE
ACROSS THE REGION, RESULTING IN A VERY DRY AND HOT AIRMASS ACROSS
THE REGION. AS SUCH, EXPECT A GRADUAL WARMING TREND THROUGH AT
LEAST MID-WEEK WITH VERY LOW CHANCES FOR PRECIPITATION ACROSS UTAH
AND SOUTHWEST WYOMING.
AVIATION
KSLC...VFR CONDITIONS WILL PERSIST FOR THE KSLC TERMINAL THROUGH THE
PERIOD. DRY AND STABLE CONDITIONS WITH MOSTLY CLEAR SKIES WILL
CONTINUE. WINDS WILL REMAIN LIGHT AND NORTHERLY THROUGH ~08Z BEFORE
TRANSITIONING TO A LIGHT SOUTHERLY FLOW OVERNIGHT. WINDS RETURN
NORTH DURING THE DAY TOMORROW.
REST OF UTAH AND SOUTHWEST WYOMING...VFR CONDITIONS WILL PERSIST FOR
THE ENTIRE AIRSPACE THROUGH THE PERIOD. DRY AND STABLE CONDITIONS
WITH A FEW HIGH CLOUDS WILL CONTINUE WITH RELATIVELY LIGHT AND
DIURNALLY DRIVEN WINDS.
FIRE WEATHER, ISSUED 158 PM MDT WED JUN 17 2026
THE STATE REMAINS UNDER THE INFLUENCE OF A STRONG
RIDGE TO OUR WEST AND LONGWAVE TROUGHING ACROSS THE EASTERN US,
ALLOWING FOR ENHANCED NORTHWESTERLY FLOW ALOFT TODAY. AS SUCH,
INCREASED WINDS ARE EXPECTED ACROSS MUCH OF SOUTHERN AND EASTERN
UTAH WITH CONTINUED VERY LOW RH. THE RIDGE SHIFTS OVERHEAD
THURSDAY, YIELDING LIGHTER WINDS ACROSS THE REGION AND CONTINUED
DRY CONDITIONS, LIMITING FIRE WEATHER CONCERNS. THE RIDGE SHIFTS
EASTWARD ON FRIDAY; CONCURRENTLY, A LOW PRESSURE SYSTEM BEGINS TO
DEEPEN ACROSS THE WEST COAST, INTRODUCING INCREASED SOUTHWESTERLY
WINDS AND MID-LEVEL MOISTURE ESPECIALLY ACROSS WESTERN PORTIONS OF
THE STATE. THIS PATTERN MAY YIELD AREAS OF CRITICAL FIRE WEATHER
CONDITIONS THROUGH SATURDAY. OVERNIGHT RECOVERIES REMAIN VERY POOR
ESPECIALLY ACROSS CENTRAL AND SOUTHERN UTAH THROUGH AT LEAST THE
WEEKEND GIVEN A VERY DRY AIRMASS IN PLACE.
