Severe Thunderstorm Warning 195, NWS Pueblo, CO

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
209 PM MDT THU SEP 3 2009

.SHORT TERM...

(TONIGHT AND TOMORROW)

CURRENTLY...WEAK FRONT MOVING ACROSS THE E PLAINS FROM N TO S. THIS
BOUNDARY FIRING OFF A FEW STRONG TO SVR TSRA ACROSS THE AREA.

TONIGHT AND TOMORROW...MAIN CONCERN WILL BE THUNDERSTORMS ALONG
BOUNDARY MOVING ACROSS THE REGION LATE THIS AFTERNOON AND EVENING.
BOUNDARY WILL BE ALONG THE US-50 CORRIDOR DURING MAX HEATING (3-4
PM) AND THIS FEATURE SHOULD LIGHT UP GIVEN THE COOL TEMPS AND 1500
CAPE....TEMPS AT -12 AT 500. SHEAR IS MARGINAL BUT WE COULD SEE SOME
LOW END SVR HAIL. LOCALIZED HEAVY RAIN WILL ALSO BE A THREAT.
PRECIP SHOULD DECREASE AS HEATING DIMINISHES.

TOMORROW IT IS EXPECTED TO BE QUITE STABLE ACROSS THE EASTERN
PLAINS. IN ADDITION FLOW ALOFT WILL BE NEARLY FROM THE DUE N. THIS
SHOULD KEEP MOST...IF NOT ALL...PRECIP PINNED UP ACROSS THE S MNTS
AND INTERIOR MTNS. LIKEWISE...I HAVE REMOVED POPS TOMORROW FROM THE
FAR E PLAINS AND KEPT VERY LOW END POPS ALONG THE ADJ PLAINS. MAX
TEMPS TOMORROW SHOULD RUN ABOUT 2 TO 4F COOLER THAN TODAY.

.LONG TERM...

(SAT-THU)

MAIN CONCERN WILL BE BROAD TROUGH MOVING TO THE N OF THE REGION MID
WEEK. COMPARED TO SIMULATIONS OF THE LAST FEW DAYS...LATEST EC MODEL
HAS COME MORE INLINE WITH GFS IN THAT THIS FEATURE WILL MOVE
GENERALLY TO THE N OF THE AREA. I STILL EXPECT A FRONT TO GO
THROUGH...BUT IT WILL BE MORE OF THE BACK DOOR VARIETY THAN A
PACIFIC FRONT TYPE VARIETY. THIS BOUNDARY WILL PROBABLY DRY OUT THE
MTNS SOMEWHAT BUT I DO NOT EXPECT IT TO COMPLETELY WIPE OUT THE
MOISTURE AT THIS TIME. THIS SAME FEATURE WILL LIKELY ENHANCE THE
PRECIP CHANCES FOR THE PLAINS WED.

IN THE MEANTIME...MOISTURE FROM THE REMNANTS OF TC JIMENA WILL
LIKELY BE MINIMAL AT BEST. AS I WRITE...QUITE A BIT OF THIS MSTR IS
SHIFTING EAST OVER THE N SXNS OF OLD MEX AND S TX. THE REMNANT LOW
OF THE TC IS FCST TO MOVE INTO THE COOL PACIFIC...AND WAT VAP IMGY
SHOWS THIS TC WILL BE MOVING INTO A VERY DRY ATMOS OVER THE PACIFIC.

ALTHOUGH WE WILL LIKELY NOT SEE MUCH MSTR FROM THIS SYSTEM...WE WILL
STILL SEE MSRT REMAINING OVER THE MTNS THROUGH AT LEAST MIDWEEK.

WITH THINGS LOOKING LESS WET AND LESS CLOUDY...I HAVE BUMPED UP MAX
TEMPS A FEW DEGREES THIS WEEKEND INTO EARLY NEXT WEEK. /HODANISH

&&

.AVIATION...

OVERALL EXPECT VFR CONDITIONS NEXT 24H AT THE TAF SITES. MAIN
CONCERN WILL BE AFTERNOON AND EARLY EVENING CONVECTION AT ALL 3
SITES. IF CONVECTION DOES OCCUR...I EXPECT IT TO BE TRANSIENT IN
NATURE AND MVFR CONDITIONS WILL LIKELY BE RELATIVELY BRIEF.

.PUB WATCHES/WARNINGS/ADVISORIES...
