DAY 4-8 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0339 AM CDT SUN OCT 24 2010
VALID 271200Z - 011200Z
...DISCUSSION...
PROGRESSIVE UPPER FLOW REGIME WILL CONTINUE INTO NEXT WEEKEND.
PROMINENT TROUGH THAT EVOLVES OVER MOST OF THE COUNTRY EARLY NEXT
WEEK WILL TRANSLATE BODILY EWD...WITH A REINFORCING SHOT OF ENERGY
DIGGING INTO THE OZARKS/MID-MS VLY ON WEDNESDAY...THEN INTO THE NERN
STATES BY WEEK'S END. THE COLD FRONT ASSOCIATED WITH THE PRIMARY
TROUGH WHICH WILL INITIALLY STALL FROM THE OH VLY TO THE SRN PLAINS
WILL BECOME ENERGETIC AGAIN WEDNESDAY-THURSDAY BEFORE REACHING THE
SERN STATES AND NRN GULF BASIN BY THURSDAY-FRIDAY.
AS GLANCING INFLUENCE OF THE MID-WEEK TROUGH BRUSHES ACROSS MODEST
BOUNDARY LAYER MOISTURE...IT IS CONCEIVABLE THAT A COUPLE OF SEVERE
THUNDERSTORMS MAY EVOLVE OVER THE OZARKS/MID-SOUTH ON WEDNESDAY.
BUT...COVERAGE/INTENSITY WILL NOT JUSTIFY A MEDIUM RANGE OUTLOOK.
LOOKING FARTHER AHEAD...CONSIDERABLE MODEL UNCERTAINTY EXISTS WITH
ARRIVAL/TIMING OF THE NEXT MOBILE UPPER SYSTEM MOVING INTO THE
ROCKIES/HIGH PLAINS NEXT WEEKEND.
..RACY.. 10/24/2010
