CURRENT WATER VAPOR IMAGERY AND UPPER AIR ANALYSIS HAS MODERATE WEST
TO NORTHWEST FLOW ALOFT ACROSS THE REGION, AS ANOTHER SHORT WAVE TROUGH
IS TRANSLATING ACROSS THE NORTHERN ROCKIES EARLY THIS MORNING. THIS,
COMBINED WITH MOIST EASTERLY UPSLOPE, HAS PRODUCED BULK AND EFFECTIVE
SHEAR VALUES TO 45-55 KTS ACROSS THE SOUTHEAST PLAINS, SUPPORTING
SEVERAL SUPERCELLS ACROSS PORTIONS OF THE I-25 CORRIDOR AND SOUTHEAST
PLAINS LATE IN THE EVENING. STORMS ARE STARTING TO CONGEAL AS THEY
ARE EXPECTED TO CONTINUE TO PUSH EAST ACROSS THE PLAINS OVERNIGHT AND
INTO WESTERN KANSAS BY DAY BREAK.
FOR THE REST OF TODAY AND TONIGHT, MOIST UPSLOPE FLOW BEHIND CONVECTION
WILL SPREAD STRATUS BACK ACROSS THE PLAINS AND INTO THE I-25 CORRIDOR
THROUGH THE EARLY MORNING HOURS, WITH SKIES CLEARING THROUGH MID MORNING
LEADING TO MOSTLY SUNNY CONDITIONS INTO THE AFTERNOON. LINGERING MOISTURE
AND DEEP LAYER SHEAR WILL BRING CHANCES OF STRONG STORMS TO SOUTHERN
SANGRES, RATON MESA AND ALONG THE SOUTHEASTERN TIER, HOWEVER, LATEST
HIGH RES DATA IS KEEP THE BULK OF STORMS SOUTH OF THE REGION ACROSS
NORTHEAST NEW MEXICO. OTHERWISE, THE DRIER AIR FILTERING ACROSS SOUTH
CENTRAL COLORADO WILL BRING CRITICAL RH LEVELS OF 5 TO 10 PERCENT
ACROSS PORTIONS OF THE CONTDVD AND THE UPPER ARKANSAS RIVER VALLEY,
HOWEVER WINDS WILL REMAIN GENERALLY BELOW CRITICAL THRESHOLDS, LEADING
TO ELEVATED FIRE DANGER THROUGH THE DAY.

ON FRIDAY. TEMPERATURES WARM BACK ABOVE SEASONAL LEVELS ON FRIDAY,
WITH HIGHS MAINLY IN THE 90S ACROSS THE PLAINS, AND INT THE 60S, 70S
