Severe Thunderstorm Warning 239, NWS Albuquerque, NM

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBUQUERQUE NM
225 PM MDT WED SEP 22 2004

.DISCUSSION...UPPER LEVEL TROUGH SLOWLY PROGRESSING EASTWARD THIS
AFTERNOON. HAVE HAD A BIT OF ISOLATED CONVECTION ACROSS THE NORTH
UNDER THE COLD POOL AS WELL AS BACK BUILDING STORMS TOWARDS THE EAST
CENTRAL PLAINS FROM TEXAS. THE BACK BUILDING HAS SLOWED HOWEVER.
VERY SHALLOW FROPA PER WIND PROFILERS STRUNG ACROSS THE EAST
CENTRAL PLAINS. FINALLY GOT THE WIND SHIFT AT TCC BUT PER LATEST FDX
IMAGERY NOT TOO FAR PAST TCC. CURRY AND ROOSEVELT COUNTIES STILL
UNDER THE GUN FOR ISOLATED SEVERE WX LATE THIS AFTERNOON INTO THE
EARLY EVENING BEFORE THINGS STABILIZE. ELSEWHERE LOOK FOR THE FAIR
WEATHER CU TO DISSIPATE THIS EVENING LEAVING CLEAR TO MOSTLY CLEAR
SKIES WESTERN THREE QUARTERS OF THE AREA. WITH THE CLEAR SKIES AND
RATHER DRY AIR IN PLACE...DEWPOINTS IN THE SINGLE DIGITS TO 20S
LOOK FOR SIGNIFICANT RADIATIONAL COOLING TONIGHT. WILL HOLD OFF ON
ANY FREEZE WARNING. EXPECT NORTHERN PORTIONS OF ZONE 3 TO
NEAR THE FREEZING MARK AS WELL AS THE NORTHWEST PLATEAU AND PORTIONS
OF THE NORTHEAST HIGHLANDS. REALLY NEED UPPER 20S FOR 2 TO 3 HOURS
FOR A HARD...KILLING FREEZE. THE ESTANCIA VALLEY WILL BE
INTERESTING...PERHAPS 30 TO 31 DEGREES THERE BUT AGAIN...NOT THE
WIDESPREAD KILLING FREEZE ACROSS THE WHOLE ZONE.

RATHER STABLE WITH DRY AIR GETTING ENTRAINED IN WILL LIMIT
CONVECTION SO TOOK OUT THE SLIGHT CHANCE POPS ACROSS THE EAST
THURSDAY. FEEL THAT THE TROUGH WILL HAVE PROGRESSED JUST FAR ENOUGH
EAST. RATHER NICE EARLY FALL DAY ON TAP FOR TOMORROW WITH BELOW
SEASONABLE TEMPERATURES EXPECTED.

RETURN FLOW PATTERN SHAPING UP FOR LATE THURSDAY NIGHT...FRIDAY
INTO THE WEEKEND PER BOTH ETA AND GFS RUNS. BASED ON THE TIME OF
YEAR HAVE TO GO BULLISH WITH THE LOW CLOUD INTRUSIONS FROM THE
SOUTHEAST. EXPECT WIDE SPREAD COVERAGE FRIDAY NIGHT ACROSS THE
EAST CENTRAL/SOUTHEAST PLAINS AS WELL AS ALONG THE FRONT RANGE OF
THE CENTRAL MOUNTAINS. NOT SURE ABOUT FOG...PROBABLY PATCHY BUT NOT
ENOUGH CONFIDENCE TO PICK THE EXACT AREAS RIGHT NOW. WAIT AND
SEE WHAT IS PRODUCED THURSDAY NIGHT. REAL DEPENDENT ON RESIDENT
MOISTURE FROM THE PAST SYSTEM. LIFTED INDEX DEPICTED TO RANGE FROM
-1 TO -3 GOOD CHUNK OF THE FORECAST AREA FRIDAY AND INCREASED 850 TO
500 MB LAPSE RATES TO BETWEEN 7.5 TO 8 DEGREES CELSIUS. LATE
SEPTEMBER WILL MINIMIZE THE CONVECTIVE DEVELOPMENT BUT HAVE TO FIGURE
ON SOME KIND OF DEVELOPMENT. EXPECT CONVECTION TO FAVOR THE
MOUNTAINS DURING THE DAY AND BLEEDING OVER INTO THE EVENING HOURS AS
WESTERLY STEERING FLOW OF 10 TO 15 KNOTS TAKES THE CELLS INTO THE
PLAINS. ALSO SEE SOME WEAK UPSLOPE DEVELOPING ALONG THE EAST SLOPES
OF THE CENTRAL MOUNTAINS WITH HIGH PRESSURE TO THE EAST. PROBABLY GET
SOME KIND OF WEAK CONVERGENCE ZONE OUT OF THAT. ONE WILDCARD WILL BE
THE VORTICITY TRANSLATION WHICH IS EXPECTED UNDER A WESTERLY FLOW.
UPPED POPS AND COVERAGE FRIDAY THROUGH SATURDAY INTO SUNDAY. BUT NOT
CONFIDENT ENOUGH TO PLACE SCATTERED POPS ANYONE PLACE DUE TO THE
WILDCARD. IT LOOKS AS THOUGH THE INSTABILITY GOES DOWN SLIGHTLY ON
SATURDAY WITH LI/S BETWEEN 0 TO -1 AND LAPSE RATES 7 TO 7.5 BUT THE
SOUTHEAST STEERING FLOW MOISTURE INCREASE SHOULD BE MORE PRONOUNCED.
THUS AN OVERALL WASH AS FAR AS COVERAGE IS CONCERN. AGAIN VORTICITY
TRANSLATION THE WILDCARD WITH UPSLOPE FLOW INCREASED EVEN MORE. ALSO
FEEL THAT THE LOW CLOUDS WILL MOST LIKELY LINGER ACROSS PORTION OF
THE EAST A GOOD CHUNK OF THE DAY THUS AFFECTING INSTABILITY THERE.

WEATHER FAIRLY MUDDLED NEXT WEEK WITH A PSEUDO HIGH OVER LOW BLOCKING
UPPER AIR PATTERN. BOTH GFS AND ECMWF DEPICT THE POLAR JET WELL
INTO CANADA SO WILL BE LOOKING TOWARDS THE PINCH OFF LOWS FOR POP
FORECASTING...ESPECIALLY SINCE WE WILL BE PROGRESSING INTO OCTOBER.
DIDNT REALLY CHANGE MUCH IN THE EXTENDED. JBW
