KEY MESSAGES
- ANOTHER ROUND OF SCATTERED SHOWERS AND STORMS WILL CONTINUE
THROUGH THE EVENING. THE MAIN THREATS INCLUDE GUSTY OUTFLOW
WINDS AND LIGHTING.
- WARM AND DRY CONDITIONS RETURN FOR THE WEEKEND.
SHORT TERM /THROUGH THURSDAY NIGHT/
ISSUED AT 242 PM MDT WED JUN 25 2025
SHOWERS AND THUNDERSTORMS ARE ONGOING, PRIMARILY NORTH OF I-70 AND
ALONG THE DIVIDE. TRAFFIC CAMERAS ARE SHOWING A MIX OF VIRGA AND
PRECIPITATION REACHING THE GROUND WITH THESE STORMS. THE PRIMARY
CONCERNS FROM TODAY'S WEATHER WILL BE LIGHTNING AND GUSTY
OUTFLOW WINDS UP TO 50 MPH. THE AVAILABLE ATMOSPHERIC MOISTURE
IS FOCUSED WHERE WE HAVE BEEN SEEING STORMS, NORTH OF I-70 AND
ALONG THE DIVIDE, BUT PWAT ANOMALIES ASSOCIATED WITH THIS
MOISTURE ARE MINIMAL AT ONLY AROUND 125% OF NORMAL. A WEAK
SHORTWAVE HAS PROVIDED SUPPORT WHERE MOISTURE IS ELEVATED.
DRIER AIR MOVES IN THIS EVENING, WHICH WILL END TODAY'S SHOWERS
AND THUNDERSTORMS. THIS DRY AIR REMAINS IN PLACE OVER THE
COMING DAYS, KEEPING PRECIPITATION CHANCES VERY LOW. DESPITE THE
DRY CONDITIONS, FIRE WEATHER CONCERNS ARE LIMITED IN THE SHORT
TERM AS A WEAKER PRESSURE GRADIENT MOVING IN AND STRONGER WINDS
ALOFT MOVING AWAY FROM OUR CWA GENERALLY KEEPS SURFACE
WINDSPEEDS BELOW CRITICAL FIRE WEATHER THRESHOLDS.
LONG TERM /FRIDAY THROUGH WEDNESDAY/
ISSUED AT 242 PM MDT WED JUN 25 2025
GOING INTO THIS WEEKEND CONDITIONS REMAIN DRY AS A RIDGE OF HIGH
PRESSURE BUILDS OVER THE INTERMOUNTAIN WEST. IN ADDITION TO A DRY
PATTERN TEMPERATURES CLIMB TO 5-10 DEGREES ABOVE NORMAL FOR THE
WEEKEND. UNDER THE RIDGE WINDS RELAX SO CRITICAL FIRE WEATHER IS NOT
MUCH OF A CONCERN ALTHOUGH LOCALIZED RED FLAG IS POSSIBLE IN SPOTS.
EARLY NEXT WEEK WE SEE SIGNS OF THE HIGH PULLING IN MOISTURE FROM
THE SOUTH, WHICH WILL RESULT IN A UPTICK IN AFTERNOON CONVECTION. A
TROUGH OVER SOCAL WILL ALSO WORK TOGETHER WITH THE HIGH TO FUNNEL
MOISTURE INTO THE AREA. EVENTUALLY IT MAY TRACK OVER THE REGION AND
PROVIDE EXTRA LIFT FOR MORE WIDESPREAD SHOWERS, BUT BEING SO FAR OUT
THESE DETAILS ARE UNKNOWN. THE INCREASE IN SHOWERS AND STORMS EARLY
NEXT WEEK COULD MEAN COOLER TEMPERATURES DUE TO THE RAIN AND CLOUDS
ESPECIALLY IN THE MOUNTAINS.
AVIATION /00Z TAFS THROUGH 00Z FRIDAY/
ISSUED AT 552 PM MDT WED JUN 25 2025
A FEW SHOWERS AND ISOLATED THUNDERSTORMS CONTINUE MOSTLY ALONG
AND NORTH OF THE I-70 CORRIDOR. THESE STORMS WILL DIE DOWN OVER
THE NEXT FEW HOURS WITH CONDITIONS REMAINING QUIET AFTER ABOUT
04Z. PRIMARY RISKS FROM THESE STORM ARE STRONG OUTFLOW WINDS
WITH GUSTS TO 50KTS POSSIBLE AND THE OCCASIONAL LIGHTNING.
OTHERWISE, EXPECT VFR CONDITIONS AND LIGHT TERRAIN DRIVEN WINDS
ACROSS THE REGION THROUGH THE NEXT 24 HRS.
