241 PM MDT TUE JUN 5 2007

.SHORT TERM...
(TONIGHT AND WEDNESDAY)

CURRENTLY/TONIGHT...CONVECTION SLOW TO DEVELOP TODAY AS WARMING MID
LEVEL TEMPS AND CIRRUS SHIELD HAVE SUPPRESSED ACTIVITY EARLY THIS
AFTERNOON. THIS IS CHANGING AS OF 20Z...AS CLEAR SLOT BETWEEN CIRRUS
BANDS HAS ALLOWED ENOUGH HEATING FOR ISOLATED STORMS TO FIRE ALONG
THE EASTERN MOUNTAINS AND RATON MESA. CAPES OVER THE AREA SUFFICIENT
FOR STORMS...WITH VALUES ABOVE 1000 J/KG OVER THE EAST...ALONG WITH
SLIGHTLY IMPROVED 0-6KM SHEAR OF AROUND 30 KNOTS. WEAK WARM FRONTAL
BOUNDARY TO THE NORTH OF ARKANSAS RIVER IS LIFTING SLOWLY
NORTH...WITH AREA OF MODEST SURFACE MOISTURE CONVERGENCE MOVING
NORTHWARD WITH THE BOUNDARY. WOULD THUS EXPECT STRONGEST STORMS WILL
DEVELOP IN NORTHEAST COLORADO TO THE NORTH OF THE WARM FRONT...WHERE
SHEAR AND MOISTURE CONVERGENCE ARE MAXIMIZED. STILL...GIVEN THE
RELATIVELY HIGH INSTABILITY...SOME SEVERE POTENTIAL OVER THE PUEBLO
CWFA IF STORMS OVER THE MOUNTAINS CAN SURVIVE AND MAKE IT EAST OF
I-25. KEPT POPS ONLY IN THE ISOLATED CATEGORY...THOUGH MAY
REEVALUATE OVER THE NEXT 2 HOURS IF CONVECTION REALLY GETS GOING.
FARTHER WEST...INCREASING SOUTHWEST FLOW AND DRIER AIR MASS
ADVECTING INTO WESTERN CO ARGUE FOR REMOVAL OF POPS FROM AREAS WEST
OF THE SAN LUIS VALLEY FOR THIS EVENING.

WEDNESDAY...STRONG UPPER TROUGH DIGS INTO THE GREAT BASIN WITH EARLY
SPRING LIKE 130 KNOT UPPER JET MIGRATING ACROSS THE STATE DURING THE
DAY. DEEP LAYER OF DRY AIR AND DOWNSLOPE DEVELOPING OVER THE SAN
LUIS VALLEY/EASTERN MOUNTAINS AND PLAINS SHOULD ENSURE DEEP
MIXING...AND WITH 700 MB WINDS OF 50 KNOTS AND 500 WINDS UP TO 80
KNOTS...POTENTIAL IS THERE FOR HIGH WIND CRITERIA GUSTS AT MANY
LOCATIONS. NEGATIVE FACTOR IS RATHER BAGGY LOOKING SURFACE PRESSURE
GRADIENT OVER THE PLAINS...WITH NAM HINTING AT WEAK SURFACE LOW
SOUTH OF KLHX WHICH COULD LIMIT SPEEDS SLIGHTLY. WILL KEEP HIGHLIGHT
AS A WATCH FOR NOW AND LET MID SHIFT MAKE THE CALL ON UPGRADE.
WEATHER CONDITIONS MEETING CRITICAL FIRE WEATHER PARAMETERS ARE
LIKELY ON WEDNESDAY...HOWEVER WITH FUEL MOISTURES RUNNING HIGH...NO
FIRE WEATHER HEADLINES ARE ANTICIPATED. KEPT THE LOW POPS FOR
WESTERN ZONES ALONG THE CONTINENTAL DIVIDE...AS COLD POOL ALOFT AND
MOISTURE ASSOCIATED WITH THE UPPER LOW MOVE ACROSS. GUIDANCE TEMPS
MIGHT BE A LITTLE TOO COOL FOR THE EAST GIVEN THE DEPTH OF
MIXING...SO NUDGED GRIDS UP A DEGREE OR 2 ABOVE MACHINE NUMBERS.

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

LONG TERM ISSUES INCLUDE WINDS WEDNESDAY NIGHT INTO THURSDAY...
COOL TEMPERATURES THURSDAY AND FRIDAY...SOME GENERALLY LIGHT SNOW
POTENTIAL OVER THE CENTRAL MOUNTAINS FROM WEDNESDAY NIGHT INTO
THURSDAY AND THEN AMOUNT OF WARMING FROM SATURDAY INTO NEXT
TUESDAY.

LATEST LONGER TERM MODELS HAS UNSEASONABLE CLOSED UPPER LOW
CENTERED OVER CENTRAL WYOMING AT 00Z THURSDAY...WHICH THEN MOVES
INTO EASTERN NORTH DAKOTA BY 18Z THURSDAY AND THEN INTO ONTARIO
CANADA ON FRIDAY. FROM LATER FRIDAY INTO NEXT TUESDAY...ZONAL TO
SOUTHWEST FLOW IS PROJECTED TO OCCUR OVER THE CWFA.

AS THE UPPER LOW MOVES TO THE NORTH OF THE CWFA WEDNESDAY NIGHT
INTO THURSDAY...PROJECT THAT HEALTHY WINDS WILL BE NOTED...ESPECIALLY
WEDNESDAY EVENING...THEREFORE KEEPING HIGH WIND WATCH IN PLACE
WEDNESDAY EVENING.

COOL AIR...ESPECIALLY FOR EARLY JUNE...THEN SWEEPS ACROSS CWFA
THURSDAY AND FRIDAY AND HAVE DEPICTED THIS IN IMPENDING GRIDS/ZONES.
ALSO...HAVE PAINTED A FEW INCHES OF SNOW OVER PORTIONS OF THE
CENTRAL MOUNTAINS FROM WEDNESDAY NIGHT INTO THURSDAY NIGHT.
GENERALLY ISOLATED POPS SHOULD BE NOTED DURING THE LONG TERM WITH
THE MOST PROMISING DEEPER MOISTURE RETURN OVER SECTIONS OF THE
EASTERN PLAINS EXPECTED SATURDAY INTO SUNDAY. FINALLY...ABOVE
CLIMATOLOGICAL AVERAGE TEMPERATURES PROJECTED TO RETURN TO THE
REGION FROM SATURDAY INTO NEXT TUESDAY WITH THE WARMEST
TEMPERATURES EXPECTED MONDAY AND TUESDAY.

CENTRAL...SOUTH CENTRAL AND SOUTHEAST COLORADO.

.DAY ONE...TODAY AND TONIGHT

ISOLATED THUNDERSTORMS WILL BE POSSIBLE ACROSS SOUTH CENTRAL AND
SOUTHEAST COLORADO TODAY...WITH THUNDERSTORMS DEVELOPING ACROSS THE
MOUNTAINS BY 1 PM...THEN DRIFTING OFF ACROSS THE INTERSTATE 25
CORRIDOR AFTER 2 PM...AND ACROSS THE REMAINDER OF THE SOUTHEAST
PLAINS AFTER 3 PM.  ONE OR TWO STRONG TO SEVERE THUNDERSTORMS WILL

SOME UNCERTAINTY EXISTS AS TO WHETHER SUFFICIENT LOW LEVEL MOISTURE
WILL BE IN PLACE BY THIS AFTERNOON TO SUPPORT SEVERE THUNDERSTORMS

PASO COUNTY MAY SEE THE HIGHEST POTENTIAL FOR SEVERE THUNDERSTORM
DEVELOPMENT.  ACROSS THE REMAINDER OF THE THREAT AREA...WARMING
TEMPERATURES IN THE MID LEVELS OF THE ATMOSPHERE COMBINED WITH DRYING
IN THE LOW LEVELS MAY END UP SUPPRESSING AFTERNOON THUNDERSTORM
DEVELOPMENT. HOWEVER...GUSTY OUTFLOW WINDS FROM THUNDERSTORMS WHICH
DEVELOP ACROSS THE MOUNTAINS...MAY BE SUFFICIENT TO BREAK THROUGH
THE WARM LAYER ALOFT...ALLOWING ONE OR TWO STRONG TO SEVERE
THUNDERSTORMS TO DEVELOP.
