Severe Thunderstorm Warning 74, NWS Pueblo, CO

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
130 PM MDT SAT JUN 19 2004

.SHORT TERM...
(TODAY AND TONIGHT)

THUNDERSTORMS HAVE ALREADY DEVELOPED IN THE CENTRAL MTS AND HAVE
SPREAD E INTO FREMONT AND TELLER COUNTIES.  SEVERE POTENTIAL FOR
THE EAST THIS EVENING IS THE MAIN CONCERN. LOW CLOUDS HAVE BEEN
BREAKING UP OVR A GOOD PORTION OF THE SE PLAINS ALLOWING FOR
SUFFICIENT HEATING TO ACT WITH THE AVAILABLE MSTR WHICH SHOULD GET
SOME THUNDERSTORMS GOING SOON AND KEEP THEM GOING INTO THE EVENING.
MESOETA SHOWS BEST CAPE ALONG THE I-25 CORRIDOR THE REST OF THIS
AFTERNOON AND THEN SPREADING EAST IN THE EVENING. 0-6KM BULK SHEAR
VALUES FOR THIS AFTERNOON AND EVENING ARE GOOD AT 40 TO 50KTS TO GET
SOME STORMS ROTATING. WILL KEEP SEVERE MENTION IN THE ZONES OVR ALL
THE ERN PLAINS THIS EVENING.  LATER TONIGHT LOW LVL EASTERLY WINDS WL
AGAIN BRING IN LOW CLOUDS AND MAYBE SOME FOG.

BY SUNDAY MORNING THE UPSLOPE LAYER WL DECREASE AS THE 700MB WINDS
SWITCH FROM AN EASTERLY DIRECTION TO WEST.  IT IS EXPECTED THAT
THE INCREASE IN MID LVL WESTERLY FLOW WL HELP PUSH THE MSTR E ON
SUNDAY MORNING WITH DOWNSLOPE WINDS DEVELOPING FOR THE AFTERNOON
HRS AT THE SFC. MODELS DO NOT SHOW ANY PCPN OVR THE FORECAST AREA
SUNDAY...BUT WITH A SHRTWV EXPECTED TO MOVE ACRS SRN PORTIONS OF
THE STATE DURING THE DAY...WL LEAVE IN ISOLD POPS MOST AREAS. 700MB
TEMPS ON SUNDAY WARM ABOUT 2 OR 3 DEGREES AND WITH FEWER CLOUDS ON
THE PLAINS AND DOWNSLOPE TO ASSIST IN WARMING...TEMPS ON THE SE
PLAINS SHOULD BE BACK INTO THE 80S AND POSSIBLY LOWER 90S.  WRN
AREAS WL SEE LITTLE CHANGE IN TEMPS.

.LONG TERM...
(SUNDAY NIGHT THROUGH SATURDAY)

BRIEF REPRIEVE IN THUNDERSTORM CHANCES WILL COME QUICKLY TO AN END
SUNDAY NIGHT AS ANOTHER COLD FRONT MOVES THROUGH SOUTHEAST COLORADO
BEHIND DEPARTING SHORTWAVE WHICH MOVES THROUGH NORTHERN PLAINS
STATES. WILL HAVE TO WATCH KIOWA AND PROWERS COUNTY FOR SVR
POTENTIAL SUNDAY EVENING ALONG/EAST OF THE FRONTAL BOUNDARY...AS 0-
6KM SHEARS ARE AROUND 55KTS...DEW POINTS IN THE LOWER 50S...WITH SB
CAPES 1000-2000 J/KG. HAVE BUMPED UP POPS IN THIS AREA IN THE
EVENING.

MONDAY...UPSLOPE FLOW BEHIND FRONTAL BOUNDARY WILL BE WELL
ESTABLISHED ACROSS REGION.  SOME DISCREPANCIES EXIST WRT DEW POINTS
TUESDAY AFTN...WITH MESO-ETA SHOWING DEW POINTS IN THE LOWER 40S...
WHILE GFS HAS DEW POINTS IN THE 50S...WITH MESO-ETA HAVING THE
FRONTAL BOUNDARY FURTHER SOUTH THAN GFS ACROSS CENTRAL TX/OK
BY AFTN. AMOUNT OF LOW LEVEL MOISTURE...AND STABILITY BEHIND FRONT
WILL BE THE MAIN CHALLENGES AS FAR AS THUNDERSTORM COVERAGE GOES.
HAVE GONE CLOSER TO THE GFS FOR DEW POINTS ON MONDAY FOR NOW.  WITH
AFTN HEATING AND ANOTHER DISTURBANCE MOVING THROUGH NORTHWEST FLOW...
WILL BRING ANOTHER CHANCE FOR SCATTERED THUNDERSTORMS.  HAVE COOLED
OFF MAX TEMPS A BIT...AND HAVE BUMPED UP POPS.  HOWEVER...IF MESO-
ETA IS CORRECT WITH THE LOW LEVEL MOISTURE...THEN MONDAY COULD BE A
DRIER QUIETER DAY THAN GRIDS PORTRAY. SVR POTENTIAL WILL AGAIN BE
THERE WITH DEEP LAYER SHEARS AROUND 50 KTS. AGAIN...STILL DRIER OUT
WEST...BUT ENOUGH MOISTURE TO WARRANT SOME ISOLATED SHOWERS AND
THUNDERSTORMS PRODUCING GUSTY WINDS BUT LITTLE RAIN.

TEMPERATURES WARM A BIT FOR TUESDAY AS AIR MASS MODERATES AND
SOUTH TO SOUTHEASTERLY LOW LEVEL FLOW KEEPS DEW POINTS IN THE 50S
ACROSS SOUTHEAST COLORADO. AGAIN...ANOTHER SVR POTENTIAL DAY WITH 0-
6KM SHEARS AROUND 40 KTS OR SO.

NOT MUCH CHANGE MADE TO GRIDS FOR THE REMAINDER OF THE EXTENDED.
NORTHWEST FLOW REMAINS ACROSS REGION ALOFT...SENDING PERIODIC
REINFORCING SURGES OF COOL MOIST AIR INTO SOUTHEAST COLORADO. GFS
BRINGS NEXT STRONGER COLD FRONT INTO AREA FOR FRI NIGHT.  IN
GENERAL...HAVE BUMPED UP POPS A BIT EACH AFTERNOON...AND KEPT MAX
TEMPS AT OR SLIGHTLY COOLER THAN MEX GUIDANCE.  WILL HAVE TO WATCH
FOR POTENTIAL FOR SVR THUNDERSTORMS EACH DAY AS NORTHWEST FLOW ALOFT
OVER LOW LEVEL EASTERLIES WILL PROVIDE FAVORABLE SHEAR PARAMETERS FOR
SEVERE THUNDERSTORMS.  -KT

.DAY ONE...TODAY AND TONIGHT.

A FEW SEVERE THUNDERSTORMS WILL BE POSSIBLE AGAIN THIS AFTERNOON

STORMS WILL HAVE THE POTENTIAL TO PRODUCE HAIL RANGING FROM 1 TO
2 INCHES IN DIAMETER...WIND GUSTS TO 60 MPH OR MORE...HEAVY RAIN
...AND DANGEROUS LIGHTNING.  ALSO...SUFFICIENT WIND SHEAR WILL
EXIST IN THE ATMOSPHERE TO PRODUCE ROTATING THUNDERSTORMS...CAPABLE
OF PRODUCING A TORNADO.  THE AREA OF GREATEST THREAT TODAY WILL LIE
ACROSS THE EASTERN COLORADO PLAINS.  HOWEVER...A THUNDERSTORM
PRODUCING LARGE HAIL WILL BE POSSIBLE ANYWHERE FROM THE SANGRE

WEST OF THE SANGRE DE CRISTO CREST...AND ACROSS LAKE AND CHAFFEE
COUNTIES...ISOLATED TO WIDELY SCATTERED THUNDERSTORMS ARE EXPECTED
TODAY. THIS ACTIVITY WILL BE CAPABLE OF PRODUCING WIND GUSTS TO 45
MPH AND DANGEROUS CLOUD TO GROUND LIGHTNING.

A FAVORABLE WEATHER PATTERN FOR AFTERNOON AND EVENING THUNDERSTORMS
WILL CONTINUE ACROSS THE AREA WELL INTO NEXT WEEK.  SHOWERS AND
THUNDERSTORMS WILL BE POSSIBLE NEARLY EVERY DAY...ALONG WITH THE
POTENTIAL FOR A FEW SEVERE STORMS...CAPABLE OF PRODUCING 1 TO 2
INCH DIAMETER HAIL...AND WIND GUSTS OVER 60 MPH.  THE NEXT BEST
CHANCE FOR SEVERE WEATHER WILL BE ACROSS THE EASTERN PLAINS OF
COLORADO ON MONDAY DURING THE AFTERNOON AND EVENING HOURS.
