SHORT TERM /THROUGH FRIDAY/
ISSUED AT 207 PM MDT THU JUL 3 2025
CURRENTLY...AN UPPER SHORTWAVE TROUGH IS CURRENTLY MOVING
NORTHEAST OUT OF SOUTHERN UTAH THIS AFTERNOON, WITH SHOWERS AND
THUNDERSTORMS DEVELOPING ACROSS THE HIGHER TERRAIN. THIS
ACTIVITY WILL CONTINUE THROUGH THIS AFTERNOON. TEMPERATURES HAVE
WARMED INTO THE UPPER 80S TO LOWER 90S ACROSS THE PLAIN, WITH A
COUPLE MORE DEGREES OF WARMING EXPECTED THIS AFTERNOON.
TEMPERATURES OVER THE SAN LUIS VALLEY WILL TOP OUT IN THE UPPER
70S TO NEAR 80.
REST OF THIS AFTERNOON AND TONIGHT...THE UPPER SHORTWAVE IS
FORECAST TO EJECT NORTHEAST ACROSS WESTERN COLORADO INTO
NORTHEAST COLORADO OVERNIGHT. ENERGY ASSOCIATED WITH THE
SHORTWAVE WILL CONTINUE TO GENERATE SHOWERS AND THUNDERSTORMS
THROUGH THIS EVENING OVER THE MOUNTAINS. AREAS ALONG THE
CONTINENTAL DIVIDE WILL SEE THE GREATEST CHANCES FOR
THUNDERSTORMS INTO THIS EVENING. THE MAIN QUESTION WILL BE HOW
FAR EAST CONVECTION DEVELOPS. THE TRACK OF THE UPPER SYSTEM WILL
KEEP THE BEST LIFT NORTH OF THE PLAINS. MOISTURE IS ADEQUATE,
WITH DEWPOINTS ALONG THE I-25 CORRIDOR IN THE UPPER 40S. MLCAPE
IS LIMITED, AND WEAK CINH IS IN PLACE. AT THIS TIME, HAVE A
FEELING MOST CONVECTION WILL DISSIPATE AS IT PUSHES OFF THE
HIGHER TERRAIN THIS AFTERNOON INTO THE EVENING. MOST HIGH-RES
GUIDANCE SUGGESTS THIS AS WELL, WITH ISOLATED ACTIVITY ON THE
PALMER DIVIDE AND RATON MESA. OVERNIGHT, A SURFACE LOW IS
FORECAST TO DEVELOP ON THE PLAINS, SENDING A COLD FRONT SOUTH
LATE TONIGHT. OVERNIGHT LOWS WILL REMAIN MILD WITH 50S AND 60S
ACROSS THE REGION.
FRIDAY...THE UPPER SHORTWAVE WILL CONTINUE NORTHEAST, WITH FLOW
ALOFT SHIFTING NORTHWESTERLY BY THE AFTERNOON. AT THE SURFACE, A
SECONDARY FRONTAL BOUNDARY WILL PUSH SOUTH DURING THE MORNING,
HELPING TO KEEP FLOW NORTHEAST TO EASTERLY ON THE PLAINS.
LIMITED MOISTURE WILL REMAIN IN PLACE ACROSS THE PLAINS, WITH
DEWPOINTS IN THE MID 40S ALONG THE I-25 CORRIDOR, AND MID 50S
NEAR THE KANSAS BORDER. INSTABILITY LOOKS TO BE SOMEWHAT HIGHER
AS WELL, AS TEMPERATURES ALOFT COOL SLIGHTLY, WITH CAPE VALUES
AROUND 700 J/KG ACROSS THE PALMER DIVIDE, AND SLIGHTLY HIGHER
NEAR THE KANSAS BORDER. EMBEDDED ENERGY IN THE NORTHWEST FLOW
ALOFT WILL LEAD TO SHOWER AND THUNDERSTORM DEVELOPMENT BY THE
AFTERNOON. FAVORED AREAS ARE ACROSS THE HIGHER TERRAIN, AND THE
PALMER DIVIDE, SOUTHEAST INTO THE PLAINS NORTH OF HIGHWAY 50.
STRONGER STORMS COULD PRODUCE LOCALLY HEAVY RAINFALL, LIGHTNING,
WIND GUSTS NEAR 50 MPH, AND HAIL TO HALF AN INCH. AS STORMS
APPROACH THE KANSAS BORDER, THEY COULD STRENGTHEN TO NEAR SEVERE
LEVELS WHERE BETTER INSTABILITY AND SHEAR EXISTS. DRY CONDITIONS
WILL PREVAIL SOUTH OF HIGHWAY 50. TEMPERATURES WILL REMAIN WARM
ACROSS THE REGION, WITH MID 80S TO MID 90S FOR HIGHS. MOZLEY
LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/
ISSUED AT 301 AM MDT THU JUL 3 2025
FRIDAY NIGHT...AS THE UPPER WAVE PASSES TO THE EAST, ISOLATED
CONVECTION ACROSS THE PALMER DIVIDE IS EXPECTED TO DIMINISH QUICKLY,
AND CHANCES ARE GOOD FOR A DECENT NIGHT FOR HOLIDAY
CELEBRATIONS. OVERNIGHT LOWS WILL COOL INTO THE 40S FOR THE HIGH
VALLEYS, BUT STAY WARM ACROSS THE PLAINS WITH UPPER 50S TO
LOWER 60S.
SATURDAY...MODELS ARE INDICATING A WEAKER UPPER SHORTWAVE CROSSING
THE ROCKIES ON SAT, THOUGH THE SOURCE OF THIS IS MUCH FARTHER NORTH.
IT WILL FORCE A COOL FRONT SOUTH, NOT BRINGING MUCH COOLING BUT WILL
BRING A WIND SHIFT. JUST SOME ISOLATED CONVECTION ACROSS THE HIGHER
TERRAIN THROUGH THE AFTERNOON WILL SHIFT TO THE EAST INTO THE
EVENING, BECOMING MORE SCATTERED AND TAPPING INTO BOTH INCREASING
CAPE ALONG THE EASTERN BORDER AS WELL AS INCREASING BULK SHEAR. SPC
HAS PAINTED A MARGINAL AREA ALONG THE FAR EASTERN CO PLAINS FOR
POTENTIAL SEVERE WEATHER. PLAN ON HIGH TEMPS IN THE 80S ACROSS THE
HIGH VALLEYS, AND MID 80S TO MID 90S FOR THE PLAINS.
SUNDAY AND MONDAY...AS THE UPPER RIDGE BUILDS BACK INTO THE DESERT
SW, THE HIGH CENTER IS FORECAST TO BE LOCATED ALONG THE NM AND AZ
BORDER, WITH SCATTERED CONVECTION CHANCES EACH AFTERNOON AND EVENING
MAINLY TIED TO THE HIGHER TERRAIN. MAXIMUM TEMPS BOTH DAYS ARE
EXPECTED TO BE RIGHT AT SEASONAL NORMALS.
TUESDAY AND WEDNESDAY...CENTER OF THE UPPER HIGH MOVES NORTH
AND PARKS OVER THE FOUR CORNERS, PROVIDING FOR DRIER AND
SLIGHTLY WARMER CONDITIONS. AFTERNOON MT CONVECTION WILL BE MUCH
MORE ISOLATED, AND HIGH TEMPS WILL CREEP UP TO SLIGHTLY ABOVE
NORMAL.
THURSDAY...ANOTHER UPPER WAVE CROSSES THE ROCKIES, INCREASING
PRECIPITATION CHANCES FOR ALL OF THE AREA BY THE EVENING. MOORE
AVIATION /00Z TAFS THROUGH 00Z SATURDAY/
ISSUED AT 542 PM MDT THU JUL 3 2025
KALS...MAINLY VFR CONDITIONS THROUGH THE NEXT 24 HOURS. LOW
CHANCE OF NEARBY SHOWERS MOVING OFF OF THE TERRAIN AND BRINGING
SOME GUSTY OUTFLOW TO THE TERMINAL. CONFIDENCE LOW, SO IT IS NOT
INCLUDED IN THE 00Z TAFS. AFTER THIS ACTIVITY CLEARS THE SAN
LUIS VALLEY THIS EVENING, VFR CONDITIONS WILL PREVAIL.
KCOS AND KPUB...VERY LOW CHANCES OF A SHOWER OR THUNDERSTORMS
THROUGH THIS EVENING. A FRONTAL BOUNDARY WILL PASS THROUGH BOTH
TERMINALS FRIDAY MORNING, WITH A NORTHERLY WIND SHIFT, AND GUSTS
NEAR 20-25 KTS POSSIBLE WITH MID-LEVEL CLOUD COVER INCREASING.
AFTERNOON THUNDERSTORM CHANCES INCREASE ON FRIDAY AFTERNOON AT
KCOS.
