KEY MESSAGES
- TEMPERATURES RETURN TO THE 90S TODAY, CONTINUALLY WARMING INTO
NEXT WEEK AS TEMPERATURES MAY REACH THE LOW 100S BY
TUESDAY/WEDNESDAY AS HEAT INDICES APPROACH 105 DEGREES.
- CHANCES FOR SHOWERS AND STORMS CONTINUE DAILY INTO EARLY NEXT
WEEK. STRONG TO SEVERE STORMS ARE POSSIBLE SUNDAY AND MONDAY
WITH DAMAGING WIND GUSTS AND LARGE HAIL AS THE MAIN THREATS.
SHORT TERM /THROUGH SUNDAY NIGHT/
ISSUED AT 241 PM MDT SAT JUL 19 2025
AN ACTIVE LATE AFTERNOON AND EVENING IS EXPECTED FOR THE TRI-STATE
AREA AS A SHORTWAVE TRAVELS ALONG THE UPPER LEVEL RIDGE WHILE A COLD
FRONT SLOWLY MOVES SOUTH ACROSS NEBRASKA INTO KANSAS. A LEE TROUGH
WILL ALSO MAKE IT'S WAY ACROSS THE TRI-STATE AREA. AS OF 1 PM MDT,
CUMULUS CLOUDS ARE BEGINNING TO FORM IN EAST-CENTRAL COLORADO.
ISOLATED STORMS MAY DEVELOP OVER THE NEXT FEW HOURS AND MOVE EAST TO
NORTHEAST. STORMS HAVE A FAVORABLE ENVIRONMENT TO WORK WITH TODAY
WITH AROUND 1200 J/KG OF SURFACE AND MIXED-LAYER CAPE, 32 KTS OF
EFFECTIVE SHEAR, AND PRECIPITABLE WATER VALUES OF 1-1.5 INCHES WITH
NEARLY INVERTED-V SOUNDINGS PROMOTING A WIND CONCERN. CONVECTIVE
ALLOWING MODELS (CAMS) ARE ALL FAVORING TWO MODES FOR THE AREA TODAY
WITH ISOLATED TO SCATTERED MUTLI-CELLS AND SUPERCELLS
DEVELOPING ALONG AND NORTH OF I-70 THIS AFTERNOON AS A CLUSTER
OF STORMS MOVES INTO THE AREA FROM ALONG THE PALMER DIVIDE. WITH
THE MULTICELL AND SUPERCELL THUNDERSTORMS, HAZARDS INCLUDE
LARGE HAIL GENERALLY UP TO 2 INCHES, BUT LARGER HAIL COULD BE
POSSIBLE IF A STORM CAN TAP INTO THE ENVIRONMENT. ONE LIMITING
FACTOR IS WE HAVE GENERALLY WEAK SHEAR IN THE 0-3 AND 0-6 KM
LAYERS TO KEEP THE HAIL LOFTED. WINDS SHOULD GENERALLY BE
GUSTING UP TO 70 MPH WITH ANY STORMS WITH MICROBURSTS POSSIBLE.
WITH THESE WINDS AND THE DRY CONDITIONS, BLOWING DUST CAN OCCUR
AND CREATE VISIBILITY REDUCTIONS ALONG THE DOWNDRAFTS AND ANY
OUTFLOWS. MORE STORMS ARE EXPECTED TO DEVELOP IN WESTERN
NEBRASKA ALONG FRONT, WHICH COULD CONTAIN MORE OF A RISK FOR
LANDSPOUTS OR BRIEF TORNADOES.
AS WE PROGRESS INTO THE EVENING HOURS, GUIDANCE FAVORS THE STORMS
CONSOLIDATING INTO MORE OF A LINE AND MERGING WITH STORMS MOVING
INTO THE AREA FROM WESTERN NEBRASKA. AS THE MERGER OCCURS, THE
PRIMARY HAZARD WILL BE DAMAGING WIND GUSTS UP TO 70 MPH AND HEAVY
RAINFALL. MAJORITY OF THE SEVERE WEATHER THREAT SHOULD EXIT THE AREA
TO THE EAST AROUND 12 AM MDT/1 AM CDT WITH SOME SHOWERS POSSIBLY
REDEVELOPING THROUGH SUNRISE. THERE IS SOME CONCERN WITH TRAINING,
HIGH PRECIPITATION STORMS CAUSING FLASH FLOODING, PRIMARILY IN OUR
NEBRASKA COUNTIES. CURRENT CONFIDENCE IN NUISANCE FLOODING IS ABOUT
40% WHILE CONFIDENCE IN FLASH FLOODING IS ABOUT 20%. OVERNIGHT LOWS
ARE EXPECTED TO BE IN THE 60S TO AROUND 70 DEGREES TONIGHT.
ON SUNDAY, THE UPPER LEVEL HIGH WILL MOVE FURTHER NORTH OVER THE
CENTRAL PLAINS WHILE ANOTHER SURFACE TROUGH DEVELOPS ALONG THE FRONT
RANGE. STORMS ARE POSSIBLE AGAIN TOMORROW WITH A MARGINAL RISK FOR
SEVERE STORMS ACROSS THE AREA. LOOKING AT CAMS, MOST STORMS SHOULD
BE SCATTERED. SHEAR IS EVEN LESS FAVORABLE TOMORROW TO REALLY GET
STORMS ORGANIZED DESPITE THE 1000-1200 J/KG OF CAPE AND MODEST LAPSE
RATES. LARGE HAIL, UP TO 1.5" AND POSSIBLY ACCUMULATING IS POSSIBLE
ALONG WITH GUSTS TO 65 MPH. HIGHS TOMORROW ARE EXPECTED TO BE IN THE
LOW TO MID 90S WITH OVERNIGHT LOWS IN THE 60S TO AROUND 70
DEGREES.
LONG TERM /MONDAY THROUGH SATURDAY/
ISSUED AT 241 PM MDT SAT JUL 19 2025
STORM POTENTIAL MONDAY AND THROUGH THE MIDDLE OF THE WEEK IS A
LITTLE MORE MURKY AT THIS TIME DUE TO THE HIGH PRESSURE CONTINUING
TO EXPAND TO THE NORTH BUT THE MAIN QUESTION WILL BE HOW FAR WEST IT
GOES. GFS SUGGESTS THE HIGH PRESSURE WILL EXPAND BACK INTO COLORADO
WHICH WOULD LIMIT STORM POTENTIAL DUE TO WIDESPREAD SUBSIDENCE. THE
ECMWF AND ECMWF ENSEMBLES HOWEVER KEEP OUT OF COLORADO AND CONTINUE
THE MONSOONAL FLOW WHICH WOULD STILL SUPPORT STORMS RIDING UP AND
AROUND THE HIGH PRESSURE. AT THIS TIME I FEEL THE ECMWF IS MORE
PLAUSIBLE AS ITS HANDLING THE FORECASTED HUMIDITY THE BEST AND THE
MONSOONAL PATTERN MAY BE ENOUGH TO HELP KEEP THE HIGH SHUNTED
FURTHER TO THE EAST.
TEMPERATURES FOR THE EXTENDED PERIOD MAY BE THE BIGGEST STORY
HOWEVER AS A VERY STRONG SIGNAL CONTINUES TO REMAIN IN PLACE FOR
WARM TO HOT TEMPERATURES. CONFIDENCE IS HIGH IN TEMPERATURES IN THE
MID 90S TO LOW 100S ACROSS THE ENTIRE AREA. THE DIFFERENCE BETWEEN
THIS UPCOMING STRETCH OF HEAT VERSUS WHAT TYPICALLY OCCURS IS THAT
WE WILL HAVE MOISTURE IN PLACE WHICH WILL KEEP THE HEAT INDICES
AROUND 100 WITH POTENTIAL FOR 105 IN OUR FARTHEST EAST COUNTIES. THE
HEAT DOESN'T APPEAR TO BE GOING ANYWHERE AS THE HIGH PRESSURE LOOKS
TO BE ENTRENCHED IN PLACE THROUGH THE END OF THE PERIOD.
AVIATION /06Z TAFS THROUGH 06Z MONDAY/
ISSUED AT 1113 PM MDT SAT JUL 19 2025
FOR KGLD & KMCK... VFR CONDITIONS ARE FORECAST FOR THE PERIOD.
THERE ARE A COUPLE OF LOW CHANCE HAZARDS (<15%) TO WATCH FOR.
THE FIRST IS SOME BRIEF FOG OR LOW CEILINGS (300-1000FT)
TONIGHT BETWEEN 09-13Z. THE OTHER IS CHANCES FOR STORMS BETWEEN
21-03Z. COMPARED TO SATURDAY, THE STORM COVERAGE IS FORECAST TO
BE MUCH LESS. BUT KEEP AN EYE OUT AS STORMS COULD FORM DIRECTLY
OVER THE TERMINALS. OTHERWISE, WINDS ARE FORECAST TO BE LIGHTER,
GENERALLY 10 KTS OR LESS, BUT VARY IN DIRECTION. THE PREVAILING
DIRECTION SHOULD GENERALLY BE FROM THE SOUTH/SOUTHEAST, BUT
WINDS COULD VARY THROUGH THE ENTIRE PERIOD (ESPECIALLY IN LIGHT
WINDS).
