SOUTH CENTRAL AND SOUTHEAST COLORADO AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO COLORADO
201 PM MDT MON JUL 23 2001

...MAIN CONCERN IS POPS & HVY RAIN POTENTIAL NEXT FEW DAYS...

CURRENTLY...SURGE FROM NE COLO IS MAKING ITS WAY ACROSS SE CO.
CURRENLTY EXTENDS FROM EL PASO OUT E TO THE LAA AREA. AM GETTING A
BIT CONCERNED THAT THE BOUNDARY IS SLOWING DOWN IN THE EL PASO
COUNTY AREA. QUITE A FEW STORMS ALREADY HAVE FORMED OVER THE FA...
MAINLY HIER TERRAIN. WAT VAP SHOWS MOISTURE PLUME OVER AREA AND
EMBEDDED VORT MAXES SEEN IN THIS FLOW. CAPES CURRENTLY IN THE 2000
J/KG WITH 5-6 K ACROSS NE CO/W KS.

SHORT TERM THROUGH TONIGHT...MESO-ETA INDICATES THE WORST WILL OCCUR
THIS EVENING AS 15 KNTS UPSLOPE INDICATED ALL THE WAY UP ABOVE 700 MB
LEVEL. EXPECT LOCAL AREAS OF HVY RAIN AND A FEW SVR CELLS AS STORM
INTERACT WITH LLVL JUICED UP AIR. MAIN THREAT WILL BE HAIL AND
LOCALLY DAMAGING WINDS. ATTM...DEFERRED FLASH FLOOD WATCH AS IT HAS
NOT RAINED IN AWHILE AND PWATS NOT ALL THAT IMPRESSIVE OFF OF 12Z
SOUNDINGS. IN ADDITION....STORMS SHOULD BE ON THE MOVE. ONLY
CONCERN WOULD BE IF STORMS WOULD ANCHOR TO THE HIGHER TERRAIN. FOR
NOW...WENT WITH MENTION OF HVY RAINS IN SIG WX AND ZFP PACKAGES.

DISCUSSION...LOTS OF INTERESTING WX TO TALK ABOUT. WITH TROUGH
REMAINING TO OUR WEST AND PLENTY OF LLVL MOISTURE ABOUT...SHOULD
SEE GOOD CHANCE OF POPS ACROSS THE CWA NEXT FEW DAYS. CONCERNS WILL
BE EXTENT OF RAINFALL AND THREAT OF STRONGER STORMS.

MODELS IN FAIRLY GOOD AGREEMENT. OVER THE NEXT FEW DAYS...FLOW ALOFT
OVER SE COLORADO IS GOING TO BE INCREASING WITH DISTURBANCES MOVING
ACROSS EACH DAY. THIS PATTERN WILL STAY WITH THE AREA UNTIL THE
TROUGH TO THE WEST LIFTS OUT. MAIN CONCERN ABOUT TOMORROW IS HOW
STABLE WILL THE ATMOS BE FROM TONIGHTS CONVECTION? MESOETA HINTS AT
THINGS GOING LATE TOMORROW DUE TO THE LOW CLOUDS THAT WILL LIKELY
BE IN PLACE TOMORROW MORNING ACROSS MOST OF THE AREA. HOWEVER WITH
DISTURBANCES COMING ACROSS...AND THE ATMOS QUITE POTENTIALLY
UNSTABLE...BELIEVE IT WILL NOT TAKE MUCH TO GET THINGS GOING.

AS WITH TONIGHT...PRECIP SHOULD END W-E...WITH THINGS ENDING LATE
ON THE FAR E PLAINS.

WEDNESDAY COULD BE A BIT INTERESTING SVR-WX WISE. WITH TROUGH JUST
TO THE WEST...FLOW AT JET LVL IN THE 50-60 KNT RANGE. 30 KNTS OF
DEEP SHEAR IN PLACE...UPSLOPE AND CAPES IN THE 1-2K RANGE SHOULD
ALLOW FOR A FEW SVR STORMS TO GET SPINNING ACROSS THE AREA DURING
THE AFTERNOON TIMEFRAME. WILL ALSO SEE CONTINUED THREAT OF SOME
LOCALLY HVY RAIN WITH THE HIGH VALUES OF LLVL MOISTURE IN PLACE.

THURSDAY...SYSTEM SHOULD BE LIFTING OUT OVER THE NW PART OF
COLORADO...THIS WILL ALLOW ONE MORE DAY OF SCATTERED AFTERNOON
STORMS ACROSS THE AREA.

FOR THE REST OF THE EXTENDED...FLOW WILL BECOME MORE ZONAL. THIS
SHOULD FORCE THE SFC TROUGH INTO KS...DRYING OUT THE E PLAINS. FOR
THIS REASON...BROUGHT EXTENDED TEMPS UP AND WENT ~SLIGHT CHANCE OF
POPS.

.PUB....NONE.
