NATIONAL WEATHER SERVICE AMARILLO TX
300 PM CDT WED MAY 7 1997

AS OF 20Z...A SURFACE LOW OVER NORTH CENTRAL KANSAS HAS AN
ASSOCIATED COLD FRONT EXTENDING SOUTHWEST TO THE CENTRAL OKLAHOMA
PANHANDLE TO THE NORTH CENTRAL TEXAS PANHANDLE INTO NOTHERN NEW
MEXICO. THE DRYLINE IS SLOWLY ON THE MOVE BUT MOVEMENT HAS BEEN
CONFINED MAINLY IN NEW MEXICO. THE DRYLINE WILL HAVE TO MAKE SOME
SIGNIFICANT MOVEMENT TO BE THE FOCUS FOR INITIATING STORMS OVER OUR
CWA. IN ADDITION...A PRE FRONTAL TROUGH...THE FRONT AND LEFTOVER
BOUNDARIES FROM YESTERDAY WILL BE THE FOCUS FOR STORMS TODAY.
ADIABATIC HEATING AHEAD OF THE FRONT HAS HELPED TO INCREASE
TEMPERATURES TODAY.  LOOKING AT THE AMA 12Z SOUNDING...CAP WAS
AROUND 5C...CAPE AROUND 560 J/KG AND GOOD MOISTURE BELOW 500MB WITH
SIGNIFICANT DRYING AT 700MB.  SOUNDING MODIFIED TO A TEMP 80 AND DEW
POINT OF 60 PRODUCES CAPE VALUES ARND 2800 J/KG...NO CAP OVER THE
EAST...A LIFTED INDEX OF MINUS 8 TO 10 AND SR HELICITY 175 M/S.

PROBLEM OF TODAY IS THE FRONTAL MOVEMENT AND TEMPERATURES FOR
PERIODS 2 THROUGH 4. NGM AND ETA ARE IN GOOD AGREEMENT THROUGH THE
PERIOD. NGM AND ETA ARE INDICATING A VORT MAX COMING ACROSS THE
NORTHERN CWA TONIGHT. THE COLD FRONT SHOULD PUSH THROUGH THE CWA BY
12Z THURSDAY. WE WILL TRIM DOWN THE POPS AND THE WORDING OF
SEVERE OVER THE NORTHWEST IN THE FIRST PERIOD. A PIECE OF THE
SURFACE HIGH WILL SURGE THROUGH THE CWA THURSDAY MORNING AND THE
MAIN HIGH OF 1025 TO 1030 MB WILL BE OVER THE CWA FRIDAY MORNING.

IN THE EXTENDED PERIODS...ALL THE MODELS ARE CLOSER IN AGREEMENT
WITH SOLUTION OF THE SURFACE HIGH OVER THE CWA AND UPPER AIR FLOW.
SURFACE HIGH OVER THE OVER AREA FRIDAY WILL MOVE SOUTHEAST.  UPPER
LEVEL FLOW WILL REMAIN WEST NORTHWEST. MRF IS CARVING OUT A
POSITIVELY TILTED TROUGH FOR LATE MONDAY AND INTO TUESDAY. WILL KEEP
A SLIGHT CHANCE THROUGH THE EXTENDED PERIOD.

HERE ARE SOME NUMBERS TO THINTK ABOUT.
