SHORT TERM /THROUGH MONDAY/
ISSUED AT 1240 PM MDT SUN AUG 16 2026
REST OF TODAY AND TONIGHT...
WITH THE MONSOON PLUME FUNNELING RIGHT INTO OUR AREA, THUNDERSTORM
ACTIVITY IS EXPECTED TO MOVE ACROSS OUR AREA THROUGH THE REST OF THE
AFTERNOON AND INTO THIS EVENING. STRONG TO SEVERE STORMS ARE STILL
ANTICIPATED, WITH CURRENT ANALYSIS SHOWING 1000 J/KG OF CAPE ALONG I-
25, INCREASING TO 2000+ FURTHER EAST. ADDITIONALLY, THE EASTERN HALF
OF OUR CWA SHOWS 30 KNOTS OR SO OF EFFECTIVE BULK SHEAR. DEWPOINTS
REMAIN IN THE 50S OVER MOST OF THESE AREAS AS WELL, CLOSE TO 60 IN
PLACES.
STORMS WILL CONTINUE TO INITIATE OVER OUR EASTERN MOUNTAINS, PUSHING
OVER THE PLAINS WITHIN THE NEXT FEW HOURS AND INTENSIFYING. MAIN
STORM HAZARDS REMAIN ON TRACK FROM PREVIOUS FORECASTS, WITH OUTFLOW
WINDS 60-70 MPH, HAIL UP TO 1.5 INCHES, HEAVY RAIN AND FLASH
FLOODING. FLOOD WATCH FOR ASPEN ACRES REMAINS IN EFFECT THRU 8PM.
STORMS WILL MOVE OFF TO THE EAST LATER TONIGHT, WITH MILD
TEMPERATURES AND LINGERING LOW-LEVEL MOISTURE SETTING THINGS UP FOR
TOMORROW.
MONDAY...
THE UPPER RIDGE WILL BUILD BACK IN OVER OUR AREA ON MONDAY, KICKING
THE MONSOON PLUME TO OUR WEST AND GIVING US A SLIGHTLY DRIER DAY.
HOWEVER, SOME LINGERING LOW-LEVEL MOISTURE SHOULD COINCIDE WITH A
WEAK PASSING SHORTWAVE ALOFT, ALLOWING FOR SOME AFTERNOON
THUNDERSTORM FORMATION, THOUGH NOTICEABLY LESS THAN TODAY. THE
MAJORITY OF CONVECTION WILL FORM OVER OUR SOUTHEAST MOUNTAINS,
SPREADING CLOSE TO THE RATON MESA AND FAR SOUTHERN PLAINS LATER IN
THE DAY, WHILE A FEW ISOLATED TO SCATTERED STORMS WILL BE POSSIBLE
OVER THE SAN JUANS AND THE PIKES PEAK REGION. STORMS ALONG THE
TERRAIN WILL BE ON THE WEAKER SIDE, WITH OUTFLOW TO 50 MPH AND HAIL
UP TO HALF AN INCH OR SO. IF STORMS MANAGE TO PERSIST LONG ENOUGH TO
MOVE ONTO THE EASTERN PLAINS, THEY WILL ENCOUNTER MOIST,
SOUTHEASTERLY SURFACE WINDS AND BETTER FORCING THANKS TO THE PASSING
SHORTWAVE. SOME STRONGER TO SEVERE STORMS (60 MPH WINDS, 1 INCH
HAIL) WILL BE POSSIBLE LATE AFTERNOON INTO EARLY EVENING.
ADDITIONALLY, ANY STORM WILL BE CAPABLE OF PRODUCING HEAVY RAINFALL,
SO FLASH FLOODING WILL STILL BE A CONCERN OVER BURN SCARS, THOUGH
AGAIN COVERAGE AND CONFIDENCE ARE BOTH LOWER FOR MONDAY THAN TODAY.
FINALLY, HIGHS WILL BE A FEW DEGREES WARMER ACROSS THE REGION, WITH
MID-80S TO LOW-90S.
LONG TERM /MONDAY NIGHT THROUGH SUNDAY/
ISSUED AT 1240 PM MDT SUN AUG 16 2026
LONG-RANGE FORECAST REMAINS ON TRACK, WITH THE UPPER HIGH EXPECTED
TO BUILD BACK IN OVER THE FOUR CORNERS REGION. THIS WILL AMPLIFY THE
UPPER RIDGE, LEADING TO DRIER CONDITIONS ACROSS THE AREA THROUGH
MOST OF THE WEEK. AFTER MUCH DRIER CONDITIONS ON TUESDAY, LINGERING
LOW TO MID-LEVEL MOISTURE WILL ALLOW FOR MORE SCATTERED THUNDERSTORM
ACTIVITY EACH DAY. STORMS WILL FIRST FORM OVER THE MOUNTAINS, WITH A
PASSING FRONT ON WEDNESDAY BRINGING PRECIPITATION BACK TO THE PLAINS
AS WELL. MEANWHILE, HIGH TEMPS WILL INCREASE ACROSS THE BOARD, WITH
HIGH-80S OVER THE VALLEYS AND HIGH-90S OVER THE EASTERN PLAINS, WITH
A LOW BUT NON-ZERO CHANCE FOR SOME MORE TRIPLE DIGITS HEADING INTO
THIS WEEKEND.
AVIATION /00Z TAFS THROUGH 00Z TUESDAY/
ISSUED AT 602 PM MDT SUN AUG 16 2026
VFR CONDITIONS ARE GENERALLY EXPECTED TO PREVAIL THROUGH THE
PERIOD. THE EXCEPTION WILL BE DUE TO ANY BRIEF MVFR CONDITIONS
WITH SHOWERS AND THUNDERSTORMS AT KCOS AND KPUB. HEAVY RAIN AND
OUTFLOW WIND GUSTS TO AROUND 40 KNOTS WILL REMAIN A CONCERN.
THIS ACTIVITY WILL WANE WITH SUNSET, WITH TERMINAL IMPACTS
EXPECTED TO END BY 05Z. CLOUDS AND WIND WILL DECREASE OVERNIGHT.
CONVECTION CHANCES RETURN TO THE AREA AFTER 18Z MONDAY, THOUGH
COVERAGE IS EXPECTED TO BE MORE ISOLATED. CURRENTLY, CONFIDENCE
IS HIGHEST AT KCOS WHERE A PROB30 GROUP WILL PERSIST.
