SHORT TERM /THROUGH TONIGHT/
ISSUED AT 1206 AM MDT TUE AUG 18 2026
100 DEGREE READINGS WILL ONCE AGAIN RETURN TO A GOOD PORTION OF THE
PLAINS TODAY, WITH READINGS FROM 100 TO 103 FROM ROUGHLY PUEBLO EAST
TO THE KS BORDER AND DOWN TOWARDS SPRINGFIELD. 90S WILL OCCUR REST
OF THE PLAINS AND MID ARK RVR VALLEY AREAS, WITH UPPER 80S IN THE
LARGER VALLEYS.
AS FOR PRECIP TODAY, NOT LIKELY. WE MAY SEE SOME VERY ISOLATED
SHOWERS OVER THE REGION BY LATE AFTERNOON, WITH A SLIGHTLY BETTER
CHANCE OF SHOWERS AND STORMS OVER THE SOUTHERN MTNS AND I-25 CORRIDOR
DURING THE EVENING HOURS AS A COOL FRONT PUSHES DOWN THE PLAINS THIS
EVENING. ONCE THE COOL FRONT MOVES DOWN, LOW LEVEL MOISTURE WILL
IMPROVE OVER THE PLAINS, AND WE COULD SEE A FEW STORMS DEVELOP ALONG
BEHIND THE FRONT OVER THE PLAINS AND I-25 CORRIDOR REGION THROUGH
THE OVERNIGHT HOURS. THERE IS A LOW CHANCE WE COULD SEE A STRONG
STORM OR TWO ALONG THE SOUTHERN MTNS/I-25 CORRIDOR REGION (INCLUDING
THE AA BURN SCAR) TOMORROW EVENING.
LONG TERM /WEDNESDAY THROUGH MONDAY/
ISSUED AT 1206 AM MDT TUE AUG 18 2026
FOR WEDNESDAY, THE FLASH FLOOD THREAT WILL RETURN TO THE AA BURN
SCAR SFC UPSLOPE FLOW COMBINES WITH NORTHWESTERLY FLOW ALOFT.
GUIDANCE SHOWS BEST MOISTURE (AND RELATED INSTABILITY) WILL BE
PINNED ALONG THE MTNS/PLAINS INTERFACE AND I-25 CORRIDOR REGION.
THIS COULD ALLOW STRONG STORMS TO PUSH SOUTHEASTWARD ALONG THE
SOUTHERN MTNS, BRINGING A HEAVY RAIN THREAT TO TEH AA BURN SCAR
DURING THE AFTERNOON TIME PERIOD. IN ADDITION TO THE HEAVY RAIN,
SHEAR WILL BE SUFFICIENT FOR ROTATING STORMS AND SEVERE STORMS WILL
BE POSSIBLE ALONG THE SOUTHERN MTNS/I-25 CORRIDOR REGION. MAX TEMPS
WILL BE ABOUT 10 DEGREES COOLER ON WED AS COMPARED TO TUE.
LOOKING AT THURSDAY INTO THE WEEKEND, IT WILL GET WARM ONCE AGAIN
WITH TEMPS PEAKING AROUND 100 ACROSS PARTS OF THE PLAINS WITH 90S
ELSEWHERE ACROSS THE LOWER ELEVATIONS AND 80S IN THE VALLEYS. THERE
WILL BE SOME MOISTURE NOTED IN THE MID LEVELS SO ISOLATED TO
SCATTERED STORMS WILL BE POSSIBLE EACH DAY MOST AREAS, WITH BETTER
CHANCES OF STORMS OVER THE CONTDVD REGION.
BY NEXT WEEK, A MORE FAVORABLE PATTERN FOR SHOWERS AND STORM
DEVELOPS AS A MORE FAVORABLE MONSOON PATTERN DEVELOPS OVER THE
REGION. THIS IS REFLECTED IN THE DETERMINISTIC GUIDANCE ALONG THE
NBM DATA PLOTS FOR THE REGION. TEMPS WILL ALSO COOL DOWN A FEW
DEGREES DURING THIS PERIOD. \/HODANISH

KCOS AND KPUB: VFR CONDITIONS ARE EXPECTED OVER THE NEXT 24 HOURS.
WINDS WILL CONTINUE TO REMAIN LIGHT, AROUND AND LESS THAN 10 KNOTS,
TONIGHT AND INTO EARLY TOMORROW AFTERNOON. AS DIURNAL MIXING
DEVELOPS, WINDS WILL INCREASE TO MAINTAIN AROUND 10 KNOTS, WITH
GUSTS TO AROUND 20 KNOTS POSSIBLE. THEN TOMORROW EVENING, A COLD
FRONT IS EXPECTED TO PUSH SOUTHWARD, WHICH WILL QUICKLY SHIFT WINDS
TO BECOME NORTHERLY IF THEY HAVEN'T ALREADY FROM SHOWER OUTFLOWS,
AND INCREASE POST FROPA. OTHERWISE, MID TO HIGH LEVEL CLOUDS ARE
EXPECTED TO START INCREASING TOMORROW AFTERNOON, WITH SCATTERED
SHOWERS DEVELOPING LATE AFTERNOON AND THROUGH THE EVENING. ANY
SHOWER THAT IMPACTS EITHER TAF SITE BRING PERIODS OF MODERATE RAIN,
WITH GUSTY OUTFLOW WINDS.
KALS: VFR CONDITIONS ARE EXPECTED OVER THE NEXT 24 HOURS. WINDS ARE
EXPECTED TO REMAIN RELATIVELY LIGHT, AT AND LESS THAN 10 KNOTS,
THROUGH THIS TAF PERIOD. BEYOND THAT, DRY CONDITIONS WITH PERIODS OF
