DISCUSSION /THROUGH THURSDAY/
ISSUED AT 1254 AM MDT FRI AUG 7 2026
AN UPPER LEVEL HIGH WILL BE CENTERED OVER THE SOUTHWEST PART OF
THE COUNTRY THROUGH SUNDAY. THIS WILL RESULT IN WEST-NORTHWEST
FLOW ALOFT ACROSS NORTH CENTRAL AND NORTHEAST COLORADO. THIS
PATTERN WILL KEEP WILDFIRE SMOKE IN THE AREA FOR THE FORESEEABLE
FUTURE. FOR TODAY, CROSS SECTIONS SHOW A VERY DRY AIRMASS WITH
CLEAR SKIES IN PLACE THROUGH THE MORNING. HIGH-BASED CUMULUS
CLOUDS WILL DEVELOP THIS AFTERNOON AND THEN DRIFT EASTWARD.
TEMPERATURES AT 700MB ARE VERY CLOSE TO YESTERDAY'S, SO EXPECT
HIGH TEMPERATURES SIMILAR TO YESTERDAY WITH MID TO UPPER 90S
ACROSS THE URBAN CORRIDOR AND NORTHEAST PLAINS. AIRMASS WARMS A
LITTLE SATURDAY, THUS HIGH TEMPERATURES WILL BE WARMER,
RANGING FROM 97 TO 105 ACROSS THE URBAN CORRIDOR AND NORTHEAST
PLAINS. WINDS WILL PICK UP OVER NORTH CENTRAL COLORADO DURING THE
AFTERNOON, WITH GUSTS AROUND 25 MPH, WHICH WILL ELEVATE THE FIRE
DANGER. SOME MOISTURE IS ABLE TO INFILTRATE THE UPPER LEVEL HIGH
OVERHEAD SUNDAY, PUSHING PRECIPITABLE WATER VALUES CLOSE TO NORMAL
OVER THE HIGHER TERRAIN. THIS IS EXPECTED TO LEAD TO ISOLATED TO
SCATTERED AFTERNOON THUNDERSTORMS. THE STORMS WILL HAVE DIFFICULTY
SURVIVING OFF THE HIGHER TERRAIN, SO WILL KEEP THE MENTION OF
SHOWERS/STORMS WEST OF I-25. TEMPERATURES TAKE A SMALL STEP BACK
SUNDAY DUE TO THE INCREASE IN MOISTURE AND CLOUDS.
VERY WARM TEMPERATURES ARE EXPECTED TO CONTINUE MONDAY AND
TUESDAY. THE RIDGE WILL WEAKEN SLIGHTLY AND DRIFT SOUTH A LITTLE.
TEMPERATURES WON'T BE AS HOT BUT HIGHS ARE STILL EXPECTED TO BE IN
THE MID TO UPPER 90S ACROSS NORTHEAST COLORADO. MOISTURE WILL
CONTINUE TO SLOWLY INCREASE WITH ISOLATED TO SCATTERED
THUNDERSTORMS EXPECTED EACH DAY. BEST MOISTURE WILL BE OVER THE
HIGHER TERRAIN AND THE BULK OF THE SHOWERS/STORMS WILL BE FOUND
THERE. NOT MUCH CHANGE FROM THE GFS AND ECMWF OVER THE PAST 24
HOURS. THE GFS SHOWS THE RIDGE REMAINING IN PLACE WITH WARMER
TEMPERATURES AND LIMITED MONSOONAL MOISTURE. THE ECMWF WEAKENS THE
HIGH AND SHOWS IT SLIDING OFF TO THE SOUTHEAST, WHICH WOULD BRING
BETTER MONSOONAL MOISTURE BEGINNING WEDNESDAY.

ISSUED AT 536 AM MDT FRI AUG 7 2026

BASED CUMULUS CLOUDS ARE EXPECTED TO FORM OVER THE HIGHER TERRAIN
AND THEN TRACK EASTWARD. CLOUD BASES WILL BE HIGH, ABOVE 12,000
FEET. SMOKE WILL LINGER AGAIN TODAY, POSSIBLY REDUCING APPROACH
SLANTWISE VISIBILITY. WINDS WILL BECOME LIGHT AND VARIABLE SOON,
BY 13Z. WINDS BECOME NORTHERLY EARLIER TODAY, AROUND 15Z AND THEN
