SHORT TERM /THROUGH TONIGHT/
ISSUED AT 1216 AM MDT FRI APR 10 2026
A COLD FRONT WILL CONTINUE TO BACKDOOR INTO THE SOUTHEAST PLAINS
THIS MORNING, WITH COOLER WEATHER MOVING IN ALONG WITH LOW
CLOUDS ACROSS THE PLAINS. SOME SHOWERS WILL BE POSSIBLE LATER
THIS MORNING. BY THIS AFTERNOON SHOWERS AND THUNDERSTORMS WILL
INCREASE, ESPECIALLY ALONG THE MTNS/PLAINS INTERFACE. BY LATE
AFTERNOON THE SHOWERS WILL MOVE EAST ACROSS THE PLAINS.
ADDITIONAL SHOWERS WILL BE POSSIBLE OVER THE CONTINENTAL DIVIDE.
PER SPC GUIDANCE, THE BEST CHANCE OF STRONGER STORMS WILL BE
ACROSS THE FAR SOUTHEAST PLAINS.
FOR TONIGHT, SHOWERS WILL CONTINUE ACROSS ALL OF THE REGION,
WITH HIGH ELEVATION SNOW LIKELY.
LONG TERM /SATURDAY THROUGH THURSDAY/
ISSUED AT 1216 AM MDT FRI APR 10 2026
SATURDAY...
IT WILL BE MUCH WARMER AND WINDY WITH SCATTERED SHOWERS AND
THUNDERSTORMS. OVERALL THE COLUMN WILL BE RELATIVELY MOIST AND
SURFACE RH VALUES WILL REMAIN RELATIVELY HIGH DURING THE
AFTERNOON TIME PERIOD. HOWEVER THIS DAY COULD BE PROBLEMATIC
FROM A FIRE WEATHER STANDPOINT AS THUNDERSTORMS WILL HAVE THE
POTENTIAL TO PRODUCE GRASS FIRES ACROSS THE PLAINS, AND WITH THE
WINDY REMAINING STRONG THROUGH THE DAY, WE COULD SEE ANY
POTENTIAL FIRES SPREADING ACROSS THE PLAINS. WE DID HAVE A FEW
FIRE STARTS LAST EVENING OVER THE FAR EASTERN PLAINS DUE TO
LIGHTNING STRIKES. WITH THIS SAID, IF WE ARE FORTUNATE TO GET
SOME DECENT RAIN OVER THE PLAINS TOMORROW (FRIDAY), THIS WOULD
ALLEVIATE THE FIRE THREAT. THIS SITUATION WILL HAVE TO BE
WATCHED CAREFULLY.
SOME OF THE STORMS WILL BE STRONG AS THE COMBO OF SYNOPTIC FLOW AND
OUTFLOW WINDS WILL ALLOW FOR STRONG GUSTS. PER LATEST SPC OUTLOOKS,
THE GREATEST THREAT WILL ONCE AGAIN BE OVER THE EASTERN PLAINS.
SUNDAY AND MONDAY...
CLASSIC DANGEROUS FIRE WEATHER SETUP. DEEP STRONG SOUTHWEST FLOW,
VERY LOW SURFACE HUMIDITY VALUES AND DROUGHT CONDITIONS WILL ALLOW
FOR RAPID FIRE SPREAD ACROSS THE PLAINS IF A FIRE SHOULD START. THE
SAN LUIS VALLEY (AND POSSIBLY THE SOUTHERN MTNS) MAY ALSO NEED FIRE
WEATHER HIGHLIGHTS THESE TWO DAYS.
TUESDAY...
A DEEP TROUGH WILL MOVE ACROSS THE REGION. IT APPEARS IT WILL
BE A BIT SLOWER AND DOES NOT APPEAR TO BE AS LONGITUDINALLY
DEEP. THIS MAY ALLOW FOR CRITICAL FIRE WEATHER CONDITIONS TO
CONTINUE OVER THE PLAINS, ESPECIALLY TUESDAY MORNING. IT DOES
APPEAR THE MOUNTAINS, ESPECIALLY ALONG THE CONTINENTAL DIVIDE
SHOULD DO WELL AS THERE APPEARS TO BE PLENTY OF MOISTURE WITH
THIS SYSTEM FOR APPRECIABLE RAIN AND SNOW ACCUMULATIONS.
WEDNESDAY AND THURSDAY...
IT WILL BE MAINLY DRY THIS PERIOD. FIRE WEATHER CONCERNS WILL
INCREASE AS RH VALUES ARE FORECAST TO BE VERY LOW BUT THE GRADIENT
ALOFT IS RELATIVELY WEAK. SO WINDS WILL BE MARGINAL AT BEST.
WILL CONTINUE TO MONITOR AS WE GET CLOSER TO THE EVENT.
LATE NEXT WEEK ANOTHER DEEP TROUGH MOVES OVER THE AREA AND FIRE
WEATHER CONCERNS WILL LIKELY ONCE AGAIN INCREASE SIGNIFICANTLY.
AVIATION /12Z TAFS THROUGH 12Z SATURDAY/
ISSUED AT 530 AM MDT FRI APR 10 2026
INCREASING AND LOWERING CLOUD COVER CAN BE EXPECTED TODAY WITH A
BRIEF WINDOW FOR MVFR TO LOW END VFR STRATUS SPREADING INTO KPUB
AND PERHAPS KCOS THIS MORNING. THESE SHOULD BREAK BY AFTERNOON WITH
WINDS SHIFTING AROUND FROM THE SOUTHEAST. SHOWERS WILL DEVELOP
OVER THE MOUNTAINS AND SPREAD INTO THE ADJACENT VALLEYS AND
PLAINS DURING THE AFTERNOON. BOTH KALS AND KPUB COULD SEE -SHRA
AT THE TERMINALS WITH GENERALLY VFR CLOUDINESS. CHANCES LOOK
TOO LOW AT KCOS TO INCLUDE -SHRA THIS AFTERNOON, BUT THIS WILL
BE MONITORED. THERE IS A BETTER CHANCE FOR MVFR STRATUS TO
SPREAD INTO BOTH KCOS AND KPUB OVERNIGHT WITHIN CONTINUED EAST
TO SOUTHEAST UPSLOPE FLOW. KALS COULD SEE ANOTHER ROUND OF
SHOWERS AFTER 06Z TONIGHT THOUGH CONDITIONS ARE LIKELY TO REMAIN
VFR. -KT
PUB WATCHES/WARNINGS/ADVISORIES
NONE.
