----------------------------------------

543 AM CDT WED OCT 2 2002

COLD FRONT ACROSS PORTIONS OF KANSAS IS EXPECTED TO CONTINUE MOVING
SOUTHWARD TODAY BEFORE SLOWING DOWN OR PERHAPS STALLING ACROSS
PORTIONS OF NORTHWEST OKLAHOMA. MODEL TENDENCIES THE LAST FEW CYCLES
HAVE BEEN TO BE LESS AGGRESSIVE WITH ITS SOUTHWARD PROGRESS. AS A
RESULT WILL USE THE ETA FRONTAL POSITION ONLY AS GUIDANCE...AND
SHIFT THE BOUNDARY 30 TO 60 MILES NORTH/NORTHWESTWARD. WITH THIS
SCENARIO...EXPECT THE COLD FRONT TO ENTER NORTHWEST OKLAHOMA THIS
AFTERNOON...BEFORE REACHING A STILLWATER TO ELK CITY LINE BY 12Z
THURSDAY. FRONT MAY THEN REMAIN STATIONARY OR RETREAT NORTHWARD ON
THURSDAY/THURSDAY NIGHT...EXACTLY HOW FAR NORTHWARD IS STILL VERY
MUCH UNCLEAR...BUT I SUSPECT THE ETA/AVN ARE TOO STRONG AND FAST
WITH THE COOL AIRMASS RETREATING AS FAR NORTH AS EASTERN KANSAS.
MEANWHILE...THE UPPER LOW SHOULD EJECT EASTWARD THROUGH THE PLAINS
WITH ANOTHER COLD FRONT MOVING INTO WESTERN OKLAHOMA AND SWEEPING
THE RESIDUAL AIRMASSES COMPLETELY EAST OF THE AREA BY MIDDAY FRIDAY.
VERY TIGHT 850-500 MB TEMPERATURE GRADIENT SITUATED ACROSS THE AREA
ALONG WITH THE EXPECTED TRAJECTORY OF THE EJECTING UPPER LOW
SUGGESTS THE SOUTHEAST HALF OF THE AREA MAY RECEIVE LITTLE OR
POSSIBLY NO RAIN OUT OF THIS DYNAMIC SYSTEM. THEIR BEST CHANCE
APPEARS TO BE EARLY FRIDAY AS SECONDARY COLD FRONT/DRY LINE MOVES
THROUGH THE AREA.

THE POTENTIAL FOR SEVERE THUNDERSTORMS WILL BE HIGHLIGHTED ACROSS
THE NORTHWEST THIRD OF OKLAHOMA FOR TONIGHT WITH THE MOST LIKELY
AREAS FOR BOUNDARY LAYER INDUCED CONVECTION ACROSS THE WESTERN TEXAS
PANHANDLE THIS AFTERNOON ALONG THE COLD FRONT AND POSSIBLY ALONG AN
EASTERN NEW MEXICO DRYLINE. THESE THUNDERSTORMS COULD THEN MOVE INTO
NORTHWEST OKLAHOMA NORTH OF THE FRONTAL BOUNDARY. CAN NOT RULE OUT
BOUNDARY LAYER INDUCED CONVECTION TODAY OR THURSDAY ACROSS OKLAHOMA
ALONG THE COLD FRONT...BUT CONSIDERING DISTANT PROXIMITY OF UPPER
LOW AND PROBABLY A STRONG SUBSIDENCE INVERSION SOUTHEAST OF THE
FRONT...CHANCES APPEAR LOW AT THIS TIME.

THE POTENTIAL FOR SEVERE THUNDERSTORMS WILL REMAIN HIGHEST NORTH OF
THE FRONT THROUGH THURSDAY. IF UPPER LOW EJECTS A BIT FURTHER SOUTH
ACROSS THE PLAINS THURSDAY NIGHT OR FRIDAY WHEN SECONDARY COLD FRONT
MOVES INTO WESTERN OKLAHOMA...A SQUALL LINE COULD DEVELOP AND
AFFECT MOST IF NOT ALL OF THE AREA.

A FEW CHANCES WERE MADE IN THE EXTENDED PERIODS. LATEST MEDIUM RANGE
MODEL GUIDANCE INDICATES ANOTHER SHORTWAVE TROUGH WILL MOVE THROUGH
THE CENTRAL US SAT NIGHT/SUN NIGHT WITH REMNANTS OF FRONTAL BOUNDARY
ACROSS CENTRAL TEXAS POSSIBLY PROVIDING A LIFTING MECHANISM FOR
CONVECTION DURING THESE PERIODS. POPS ARE NOW ONLY INCLUDED THE
SOUTHEAST HALF OF THE AREA. POPS HAVE BEEN COMPLETELY REMOVED FOR
SUNDAY NIGHT AND MONDAY.
