AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
429 AM MDT MON MAY 24 2010

.SHORT TERM...

(TODAY AND TONIGHT)

...WINDY WITH SEVERE THUNDERSTORMS OVER THE FAR EASTERN PLAINS...

SEVERAL QUESTIONS EXIST ON HOW THINGS WILL EVOLVE TODAY.  ONE THING
IS FOR CERTAIN...IT WILL BE WINDY ACROSS SOUTHERN COLORADO.  THE
MAIN QUESTIONS FOR TODAY WILL BE HOW QUICKLY THE DRYLINE ADVANCES
ACROSS THE PLAINS AND WHEN CONVECTION WILL TRIGGER ALONG THE
DRYLINE.  CURRENTLY MODELS HAVING A HARD TIME WITH LOW LEVEL
MOISTURE WITH DEW PT VALUES IN THE 50S TO LOWER 60S ACROSS THE
EASTERN PLAINS AND MODEL VALUES AROUND 10-15 DEGREES LOWER.
CONVECTION CURRENTLY FIRING ACROSS NORTHERN NEW MEXICO EARLY THIS
MORNING AND IS EXPECTED TO PROGRESS NORTHWARD THROUGH THE MORNING.
CAPE VALUES RANGING FROM 1000-1500 J/KG WITH LITTLE TO ANY CAP WHICH
SHOULD ALLOW STORMS TO BECOME STRONG VERY QUICKLY THIS MORNING.
ADDING TO THE MIX IS AN UPPER LEVEL STORM SYSTEM OVER SOUTHERN UTAH
THAT WILL EJECT NORTHEASTWARD AND BECOME INCREASINGLY NEGATIVELY
TILTED ACROSS COLORADO THIS AFTERNOON.

THE QUESTION OF HOW QUICKLY THE DRYLINE PUSHES EASTWARD ACROSS THE
PLAINS WILL DETERMINE WHERE THE MAIN SEVERE THUNDERSTORM THREAT WILL
EXIST FOR THIS AFTERNOON AND EVENING.  CURRENT MODEL ANALYSIS BRING
THE DRYLINE ACROSS THE PLAINS AND INTO WESTERN KANSAS BY 21Z THIS
AFTERNOON.  WITH MOISTURE BEING UNDERPLAYED BY THE MODELS...HAVE A
FEELING THE DRYLINE WILL BE A BIT SLOWER TO PROGRESS OUT OF COLORADO
FOR THIS AFTERNOON.  STRONG DRY WESTERLY MIDLEVEL FLOW WILL ARRIVE
OVER THE WESTERN MOUNTAINS BY 12Z THIS MORNING AND QUICKLY MIX DOWN
TO THE SURFACE WITH STRONG GUSTY WINDS BY 18Z ACROSS THE WESTERN
HALF OF THE CWA.  FORECAST WINDS ARE ON THE THRESHOLD OF HIGH WIND
WARNING CRITERIA...HOWEVER HAVE HELD OFF ON ISSUING ONE AT THIS
TIME.  WIDESPREAD WIND GUSTS TO NEAR 50 KTS WILL BE POSSIBLE ACROSS
MUCH OF THE REGION THROUGH THIS AFTERNOON.  BLOWING DUST MAY ALSO BE
A PROBLEM OVER THE SAN LUIS VALLEY AND WEST OF I-25 THIS AFTERNOON.
FIRE DANGER WILL REMAIN HIGH OVER THE SAN LUIS VALLEY WITH STRONG
WINDS COMBINED WITH HUMIDITY VALUES DROPPING INTO THE LOWER TEENS.

SEVERE WEATHER...STORMS MOVING NORTHWARD OUT OF NEW MEXICO INTO
SOUTH CENTRAL COLORADO EARLY THIS MORNING WILL HAVE PLENTY OF
INSTABILITY TO WORK WITH AND HIGH LIKELIHOOD OF BECOMING SEVERE.
THE MAIN THREATS THIS MORNING WILL BE LARGE HAIL AND OUTFLOW WINDS.
BY LATE MORNING...THE DRYLINE WILL BE PROGRESSING EASTWARD ACROSS
THE PLAINS.  INCREASED SHEAR AND CAPE VALUES CLIMBING WITH DAYTIME
HEATING WILL ALLOW FOR SEVERE THUNDERSTORMS...EAST OF HIGHWAY 350
AND QUICKLY MOVING TOWARDS THE KANSAS BORDER FROM AROUND 18Z THROUGH
00Z.  INCREASED 500 MB FLOW AND MID LEVEL WINDS WILL PRODUCE FAST
STORM MOTIONS AND ROTATING UPDRAFTS.  EXPECT THE PRIMARY THREATS TO
BE LARGE HAIL AND STRONG WINDS ALONG WITH A COUPLE
TORNADOES...ESPECIALLY OUT NEAR THE KANSAS BORDER.  EXPECT
THUNDERSTORMS TO CLEAR EASTERN COLORADO BEFORE 03Z AS THE DRYLINE
CONTINUES EAST INTO WEST CENTRAL KANSAS.  THE EVOLUTION AND MOVEMENT
OF THE DRYLINE WILL HAVE TO BE MONITORED FOR THIS AFTERNOON TO
NARROW DOWN THE MOST LIKELY AREAS TO SEE SEVERE WEATHER THROUGH THE
MORNING HOURS.

UPPER STORM SYSTEM QUICKLY LIFTS NORTH INTO MONTANA OVERNIGHT WITH
CLEARING AND WINDS SUBSIDING AS SHORTWAVE RIDGING DEVELOPS OVER THE
REGION.  KEPT OVERNIGHT LOWS ABOVE GUIDANCE...HOWEVER TEMPERATURES
WILL BE AROUND 10-20 DEGREES COOLER THAN THE PAST FEW NIGHTS.
ISSUED A FREEZE WARNING FOR THE SAN LUIS VALLEY WHERE TEMPERATURES
WILL DROP INTO THE MID 20S FOR SEVERAL HOURS TONIGHT. MOZLEY

.LONG TERM...

(TUESDAY-SUNDAY)

DEEP TROUGH OUT WEST CONTINUES TO BE THE MAJOR CONCERN.

TROUGH OUT WEST WILL RELOAD EARLY DURING THIS FCST PERIOD...AND IS
FCST TO LIFT TO THE NORTHEAST OF THE REGION AT THE END OF THIS
PERIOD. WITH THE DEEP TROUGH TO OUR WEST...AND THE HIGH AMPLITUDE
RIDGE TO OUR EAST...WE WILL SEE A DEEP SOUTHERLY FLOW OVER THE AREA
ALL THIS WEEK. THIS FLOW IN TURN WILL ALLOW FOR MOISTURE TO INCREASE
OVER THE REGION.

ALTHOUGH MOISTURE WILL BE ON THE INCREASE...FORCING TO INITIATE
CONVECTION WILL GENERALLY REMAIN TO OUR WEST THROUGH MOST OF THE
PERIOD. LIKEWISE...CHANCES FOR PRECIP OVER THE PLAINS DURING MOST OF
THE PERIOD WILL GENERALLY BE ISOLATED. THE MTNS WILL SEE A SLIGHTLY
BETTER CHANCE...BUT EVEN HERE VALUES MAY BE ISOLATED AT BEST OR LOW
END SCATTERED. ONCE THE TROUGH GETS CLOSER TO THE REGION AT THE END
OF THE WEEK WILL PRECIPITATION CHANCES INCREASE OVER THE FCST AREA.

AS FOR FIRE WX...MAIN JET REMAINS TO THE WEST FOR THE FIRST 2/3RDS
OF THIS PERIOD...SO I DO NOT EXPECT EXCESSIVELY STRONG SYNOPTIC
WINDS OVER THE REGION. ADDITIONALLY...WITH THE MOISTURE INCREASING
AT ALL LEVELS EXPECT RH VALUES TO BE ON THE HIGH SIDE. FIRE WX
ISSUES MAY BE ON THE INCREASE LATE IN THE WEEK. /HODANISH

&&

.AVIATION...

VFR EXPECTED FOR ALL TAF SITES THROUGH TOMORROW.  MAIN CONCERN WILL
BE STRONG SOUTHWESTERLY WINDS FOR LATE THIS MORNING THROUGH THE
EARLY EVENING.  WINDS WILL BEGIN TO PICK UP BY 16Z AND GUST 40 TO 50
KTS BY 18Z THROUGH 00Z THIS AFTERNOON.  BLOW DUST WILL BE POSSIBLE
AT KALS AND KPUB WITH THE STRONG WINDS WHICH MAY LOWER VISIBILITIES
TO MVFR HOWEVER CONFIDENCE IS TOO LOW TO INCLUDE IN THE TAFS AT THIS
TIME.  LLWS WILL ALSO BE A CONCERN AT ALL TAF SITES THIS AFTERNOON.
WINDS WILL BEGIN TO SUBSIDE AFTER 00Z AND QUICKLY FALL OFF
OVERNIGHT.  STRONG TO SEVERE THUNDERSTORMS WILL BE POSSIBLE THIS
MORNING ALONG THE COLORADO-NEW MEXICO BORDER AND SPREAD EASTWARD TO
THE KANSAS BORDER THROUGH 00Z.  THUNDERSTORMS WILL NOT IMPACT ANY OF
THE TAF SITES.  MOZLEY

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF CENTRAL...EAST
CENTRAL...SOUTH CENTRAL AND SOUTHEAST COLORADO.

.DAY ONE...TODAY AND TONIGHT

STRONG WINDS...LOW RELATIVE HUMIDITY VALUES AND HOT TEMPERATURES
WILL PRODUCE HIGH FIRE DANGER ACROSS THE SAN LUIS VALLEY THIS
AFTERNOON AND EVENING.

STRONG THUNDERSTORMS WITH ONE OR TWO SEVERE THUNDERSTORMS WILL BE
POSSIBLE THIS MORNING ACROSS SOUTH CENTRAL COLORADO AS AN UPPER
LEVEL STORM SYSTEM MOVES ACROSS THE ROCKIES.  THUNDERSTORMS THIS
MORNING WILL LIKELY PRODUCE HAIL UP TO 1 INCH IN DIAMETER AND STRONG
OUTFLOW WIND GUSTS.

A DRYLINE IS FORECAST TO DEVELOP AND MOVE EAST ACROSS THE EASTERN
COLORADO PLAINS BY LATE MORNING THROUGH THIS AFTERNOON.  ABUNDANT
LOW LEVEL MOISTURE AHEAD OF THE DRYLINE...STRONG WIND SHEAR AND HIGH
INSTABILITY WILL LEAD TO THUNDERSTORM DEVELOPMENT BY NOON.  THE MOST
LIKELY AREA TO SEE THUNDERSTORMS FOR THIS AFTERNOON WILL BE EAST OF
U.S. HIGHWAY 350 BY NOON...SHIFTING EAST TO THE KANSAS BORDER
THROUGH 5 PM.  AS THUNDERSTORMS PROGRESS EASTWARD ACROSS THE
PLAINS...THE POTENTIAL FOR SEVERE WEATHER WILL INCREASE WITH LARGE
HAIL WITH DIAMETERS GREATER THAN AN INCH...STRONG OUTFLOW WINDS AND
ONE OR TWO TORNADOES...ESPECIALLY NEAR THE COLORADO KANSAS BORDER.
EXPECT THUNDERSTORMS THREAT TO DIMINISH AFTER 5 PM AS THE
THUNDERSTORMS MOVE EAST INTO KANSAS.

STRONG WINDS WILL MOVE ACROSS SOUTHERN COLORADO BEHIND THE DRYLINE
LATE THIS MORNING AND AFTERNOON.  WIND GUSTS OF 50 TO 60 MPH WILL
PRODUCE HAZARDOUS DRIVING CONDITIONS ON NORTH SOUTH HIGHWAYS
INCLUDING INTERSTATE 25 AND AREAS OF BLOWING DUST.  WIND WILL
SUBSIDE THIS EVENING.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED
ACROSS THE REGION THROUGH THE PERIOD. THE BEST CHANCE FOR STRONGER
STORMS WILL BE THURSDAY AND FRIDAY WHEN ANOTHER UPPER LEVEL STORM
SYSTEM MOVES OVER THE REGION.

.SPOTTER INFORMATION STATEMENT...

WEATHER CONDITIONS THAT MEET REPORTING CRITERIA FOR SPOTTERS WILL BE
POSSIBLE THIS MORNING AND AFTERNOON OVER SOUTH CENTRAL AND EASTERN
COLORADO.
