DISCUSSION
ISSUED AT 1023 PM MDT TUE JUN 9 2026
HOT, DRY, AND BREEZY CONTINUES:
WINDS FINALLY START TO WEAKEN SOMEWHAT AS THE BASE OF THE UPPER
LEVEL TROUGH PASSES OVERHEAD AND THE PRESSURE GRADIENT BEGINS TO
RELAX A BIT. A 90-100 KNOT UPPER LEVEL JET WILL LINGER ALONG OUR
NORTHERN BORDER THROUGH THURSDAY, AND STRONG DAYTIME MIXING IS
EXPECTED TO TAP INTO IT AND BRING STRONGER WINDS DOWN TO THE
SURFACE. THIS WILL FAVOR AREAS ALONG AND NORTH OF I-70, WHERE GUSTS
OF 30-40 MPH ARE EXPECTED, AND LOCALIZED GUSTS UPWARD OF 50 MPH
POSSIBLE. WIND ADVISORIES HAVE BEEN ISSUED FOR THESE LOCATIONS FROM
NOON TO 8PM WEDNESDAY. ACROSS THE SOUTHERN HALF OF THE REGION, WINDS
WILL GUST 20-30 MPH. MUCH DRIER AIR IN THE WAKE OF THE UPPER LEVEL
TROUGH WILL KEEP DAYTIME HUMIDITIES IN THE SINGLE DIGITS TO LOW
TEENS TODAY, AND PREDOMINANTLY IN THE SINGLE DIGITS THURSDAY. SO
WHILE WINDS WON'T BE QUITE AS INTENSE AS WE'VE SEEN IN DAYS PAST,
WIDESPREAD CRITICAL FIRE WEATHER CONDITIONS REMAIN AND RAPID
WILDFIRE GROWTH, WHETHER FROM NEW OR PRE-EXISTING FIRES, REMAINS A
CONCERN.
WE FINALLY SEE A BIT OF A PATTERN SHIFT BY FRIDAY AS THE UPPER LEVEL
TROUGH THAT'S DOMINATED THE WEST COAST THIS WEEK FINALLY TRACKS
EAST. EASTERN UTAH AND WESTERN COLORADO COME UNDER MOSTLY ZONAL
FLOW, WITH A MORE RELAXED PRESSURE GRADIENT IN PLACE. PASSING WAVES
IN THE FLOW WILL RESULT IN PERIODS OF GUSTY AFTERNOON WINDS THROUGH
THE WEEKEND, AND DRY SURFACE AIR WILL REMAIN IN PLACE. AT LEAST
LOCALIZED, IF NOT WIDESPREAD, CRITICAL FIRE WEATHER CONDITIONS
REMAIN A POSSIBILITY THROUGH THE WEEKEND. INCREASED UPPER LEVEL
MOISTURE LOOKS TO RETURN SUNDAY, MEANING AT LEAST SOME INCREASED
CLOUD COVER, IF NOT A CHANCE FOR SHOWERS OR THUNDERSTORMS.
TEMPERATURES REMAIN 5-10 DEGREES ABOVE NORMAL THROUGH THE PERIOD.
AVIATION /06Z TAFS THROUGH 06Z THURSDAY/
ISSUED AT 1200 AM MDT WED JUN 10 2026
EXPECT VFR CONDITIONS WITH MOSTLY CLEAR SKIES THROUGH THE TAF
PERIOD. THE EXCEPTION ARE SOME MID TO HIGH CLOUDS ASSOCIATED
WITH A FEW LIGHT SHOWERS ALONG AND NORTH OF THE I-70 CORRIDOR
MOVING EAST OUT OF THE REGION BY ABOUT 10Z. WINDS OVERNIGHT WILL
GENERALLY BE LIGHT AND TERRAIN DRIVEN WITH GUSTY WEST TO
SOUTHWEST WINDS PICKING UP AFTER 15Z. LOOK FOR GUSTS 25 TO 35
KTS ACROSS THE SOUTHERN TAF SITES AND GUSTS 35 TO 45 KTS ALONG
AND NORTH OF THE LINE KCNY TO KGUC BETWEEN 18Z AND 02Z.
FIRE WEATHER
ISSUED AT 1023 PM MDT TUE JUN 9 2026
THE CRITICAL FIRE WEATHER PATTERN PERSISTS AT LEAST THROUGH
THURSDAY, LIKELY THROUGH THE WEEKEND, AND POSSIBLY INTO THE NEXT
WORK WEEK. WINDS BEGIN TO WEAKEN SOMEWHAT TODAY, ALTHOUGH AREAS
ALONG AND NORTH OF I-70 COULD STILL SEE GUSTS OF 30-40 MPH WITH
LOCALLY HIGHER GUSTS TO AROUND 50 MPH POSSIBLE. ADDITIONALLY DRIER
CONDITIONS WILL BE SETTLING IN WITH THE DRIEST AIR EXPECTED ON
THURSDAY WHEN THE MAJORITY OF THE REGION WILL SIT AT 5-15% MINIMUM
RELATIVE HUMIDITIES. RAPID WILDFIRE SPREAD REMAINS POSSIBLE, AND RED
FLAG WARNINGS REMAIN IN EFFECT TODAY AND THURSDAY.
