.SHORT TERM...
(TONIGHT AND TUESDAY)

...WINDS AND DRY LIGHTNING CONCERNS CONTINUE FOR THIS EVENING...WITH
GUSTY WINDS AND LOW RELATIVE HUMIDITIES CONCERNS EXPECTED AGAIN FOR
TUESDAY...

MOISTURE PLUME OVER EASTERN SECTIONS OF THE DISTRICT EVIDENT IN WV
PICS WITH MODELS HINTING AT SOME WEAK EMBEDDED SHORTWAVE ENERGY
LIFTING UP FROM NM IN 1.5PVU SFC FIELDS LATE THIS AFTN/EARLY
EVENING.  THUNDERSTORMS HAVE DEVELOPED ALONG THE EASTERN SLOPES OF
THE SANGRES...AND HAVE BEEN PERCOLATING ALONG THE SFC TROF
CONVERGENCE AXIS ACROSS LAS ANIMAS COUNTY.  SO FAR HAVE SEEN A FEW
POSITIVE LIGHTNING STRIKES ACROSS CENTRAL LAS ANIMAS COUNTY
ASSOCIATED WITH THIS ACTIVITY...AND KTAD REGISTERED A PEAK WIND GUST
TO 46 MPH FROM GUSTY OUTFLOW WINDS.  SO FAR ACTIVITY AS BEEN RATHER
ISOLATED...BUT HRRR CONTINUES TO BLOSSOM AND SPREAD THIS ACTIVITY
EASTWARD THROUGH THE LATE AFTERNOON AND EVENING...WITH SOME
SCATTERED COVERAGE ACROSS SOUTHERN SECTIONS OF THE AREA THROUGH
EARLY EVENING.  THUS...RED FLAG FOR DRY LIGHTNING
(IE...THUNDERSTORMS PRODUCING GUSTY WINDS AND LIGHTNING...BUT LITTLE
RAINFALL) STILL SEEMS WARRANTED THROUGH THE REMAINDER OF THE
EVENING.  MEANWHILE...SFC DEW POINTS HAVE DROPPED INTO THE TEENS AND
20S ACROSS WESTERN AND NORTHERN SECTIONS OF THE AREA...AND WIND
GUSTS HAVE INCREASED ABOVE RED FLAG CRITERIA ACROSS THE SAN LUIS
VALLEY...EL PASO COUNTY REGION...AND SOUTHEAST CORNER OF THE STATE.
RHS IN ALL THESE AREAS HAVE DROPPED BELOW 15 PERCENT...AS TEMPS HAVE
CLIMBED INTO THE 90S TO AROUND 100 ACROSS THE PLAINS...WITH 70S AND
80S FOR THE MOUNTAIN COMMUNITIES.  FOR TONIGHT...THUNDERSTORM ACTIVITY
IS STILL PROGGED TO DIMINISH QUICKLY WITH LOSS OF HEATING...AND SOME
MARGINAL HUMIDITY RECOVER IS EXPECTED...THOUGH THE SOUTHEAST
MOUNTAINS AND ADJACENT PLAINS WILL LIKELY SEE HUMIDITY RECOVERIES
STAY QUITE LOW OVERNIGHT...AROUND 25 TO 30 PERCENT.

UPPER TROF IS EXPECTED TO MOVE THROUGH THE UPPER GREAT BASIN...
CLIPPING BY TO THE WEST AND NORTH OF THE AREA LATER TONIGHT AND
TUESDAY.  WINDS ACROSS THE HIGH COUNTRY ARE EXPECTED TO INCREASE
OVERNIGHT AS THE UPPER JET TRANSLATES ACROSS WESTERN AND NORTHERN
PORTIONS OF THE DISTRICT.  LEE TROF DEEPENS ALONG THE LOWER EASTERN
SLOPES...AND ANY MEAGER LOW LEVEL MOISTURE FROM THUNDERSTORM OUTFLOW
THIS EVENING...WILL QUICKLY GET MIXED OUT EVEN DURING THE OVERNIGHT
HOURS AS WESTERLY WINDS KICK IN ALONG THE LOWER EASTERN SLOPES.
WOULD NOT BE SURPRISED TO SEE LOCATIONS ALONG AND WEST OF I-25
GETTING CLOSE TO RED FLAG CRITERIA EVEN IN THE EARLY MORNING HOURS.
MODERATE SOUTHWEST FLOW CONTINUES ALOFT ON TUESDAY AS THE UPPER LOW
LIFTS OFF INTO THE DAKOTAS AND ANOTHER TROF MOVES INTO THE WESTERN
U.S.  SFC LEE SIDE LOW IS PROGGED BY MODELS TO TRANSLATE EASTWARD
INTO EITHER SOUTHEAST OR EAST CENTRAL CO (DEPENDING ON THE MODEL) BY
AFTERNOON.  THIS WILL ALLOW WESTERLY WINDS TO SPREAD EASTWARD WITH
GUSTS OF 25 TO 35 MPH BY AFTERNOON ACROSS THE SAN LUIS
VALLEY...SOUTHEAST MOUNTAINS AND PLAINS.  WINDS DON/T LOOK QUITE AS
STRONG AS PREVIOUS RUNS HAD SUGGESTED...BUT STILL MAKE CRITERIA
ACROSS WESTERN AND SOUTHERN PORTIONS OF THE DISTRICT AS WELL AS THE
I-25 CORRIDOR.  A LITTLE MORE UNCERTAINTY EXISTS ACROSS NORTHERN
SECTIONS OF THE SOUTHEAST PLAINS (MAINLY ALONG AND NORTH OF HIGHWAY
50)...WHERE WINDS NEAR THE SFC TROF AXIS STAY LIGHTER.
HOWEVER...EVEN IN THESE AREAS...WINDS HAVE THE POTENTIAL TO BE GUSTY
EARLY ON...THEN DIMINISH IN THE MID AFTERNOON...ONLY TO INCREASE
AGAIN LATE TUESDAY AFTERNOON AND EVENING.  THUS WILL UPGRADE THE
FIRE WEATHER WATCH TO A RED FLAG WARNING FOR ALL AREAS. WITH DRY AIR
MOVING IN...DOESN/T APPEAR TO BE ANY CHANCE OF THUNDERSTORMS WITH
DRY LINE WELL EAST INTO KANSAS. -KT

.LONG TERM...
(TUESDAY NIGHT THROUGH MONDAY)

LONGER TERM METEOROLOGICAL ISSUES INCLUDE TEMPERATURES...INCREASING
PRECIPITATION CHANCES(INCLUDING THE POTENTIAL FOR SOME STRONG TO
SEVERE THUNDERSTORMS...MAINLY NORTHERN AND EASTERN SECTIONS) FROM
WEDNESDAY NIGHT INTO THE WEEKEND...GUSTY WINDS AT TIMES AND NEAR
CRITICAL TO CRITICAL FIRE WEATHER CONCERNS AT TIMES.

SOUTHWEST TO ZONAL UPPER FLOW PROJECTED TO CONTINUE OVER THE
LONGER TERM DURING WHILE AT THE SURFACE A NORTHEASTERLY TO
EASTERLY SURGE MOVES INTO EASTERN PORTIONS OF THE CWFA WEDNESDAY
AND REMAINS IN PLACE AND/OR IS REINFORCED AT TIMES THROUGH AT
LEAST FRIDAY.

FOR SENSIBLE WEATHER...WILL DEPICT GENERALLY DRY CONDITIONS FROM
TUESDAY NIGHT INTO WEDNESDAY WITH UPSWING IN PRECIPITATION OVER
FAR NORTHERN PORTIONS WEDNESDAY EVENING AND THEN OVER THE EASTERN
1/2 TO 2/3RDS OF THE CWFA FROM THURSDAY INTO THE WEEKEND. AS
BRIEFLY TOUCHED UPON...THE HIGHEST POTENTIAL FOR STRONG TO SEVERE
THUNDERSTORMS SHOULD BE NOTED NORTHERN(EXCLUDING THE CENTRAL
MOUNTAINS) AND EASTERN SECTIONS DURING THE TIME-FRAME.

IN ADDITION...A FEW DAYS OF COOLER/BELOW SEASONAL TEMPERATURES
WILL BE POSSIBLE ON THURSDAY AND FRIDAY(ESPECIALLY EASTERN
SECTIONS). WARMEST TEMPERATURES OF THE LONGER TERM ARE ANTICIPATED
WEDNESDAY AND THEN AGAIN BY NEXT SUNDAY AND MONDAY. GUSTY WINDS
AT TIMES ARE ALSO EXPECTED TUESDAY NIGHT...WEDNESDAY
NIGHT...THURSDAY NIGHT AND THEN AGAIN BY SUNDAY NIGHT.

DUE TO SOMEWHAT COOLER AND INCREASING ATMOSPHERIC MOISTURE CONTENT
...CONFIDENCE HAS LOWERED A BIT ON WIDESPREAD CRITICAL FIRE
WEATHER CONDITIONS DEVELOPING OVER THE CWFA ON WEDNESDAY...WITH
AREAS SUCH AS THE SAN LUIS VALLEY STILL HAVE THE HIGHEST POTENTIAL
OF REACHING SUSTAINED CRITICAL FIRE WEATHER CONDITIONS.

FOR NOW...WILL HOLD OFF ON ANY FIRE WEATHER HIGHLIGHTS FOR
WEDNESDAY AND WFO PUEBLO WILL CONTINUE TO MONITOR LATEST
REAL-TIME CONDITIONS AS WELL AS FORECAST COMPUTER SIMULATIONS
AND ISSUE HIGHLIGHTS IF WARRANTED...PLEASE STAY TUNED.

IN THE VICINITY OF KCOS.  GUSTY OUTFLOW WINDS WILL BE POSSIBLE WITH
THUNDERSTORMS WITH LOCALIZED GUSTS UP TO 50 MPH POSSIBLE.
THUNDERSTORM OUTFLOWS WILL RESULT IN ERRATIC SHIFTING WINDS THROUGH
LATE AFTERNOON AND WILL REFLECT THIS WITH TEMPO GUSTS TO 30 KTS AT
KCOS AND KPUB.  EXPECT CLEARING SKIES OVERNIGHT WITH WINDS EXPECTED
TO INCREASE AGAIN ON TUESDAY...WITH SOUTHWEST WINDS GUSTING TO 25-30
KTS AT KALS...AND TO AROUND 25 KTS FOR KPUB AND KCOS BY AFTERNOON.
