DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0105 AM CST WED DEC 08 2010
VALID 101200Z - 111200Z
...SYNOPSIS...
A MAJOR CHANGE TO THE PATTERN WILL BEGIN ON FRIDAY AS A POWERFUL
UPPER LEVEL JET STREAK DIVES SEWD ACROSS THE FOUR CORNERS AND INTO
THE SERN PLAINS BY 12Z SAT. IN RESPONSE TO THIS DIGGING TROUGH...LOW
PRESSURE WILL FORM OVER THE SRN PLAINS WITH SLY RETURN FLOW
INCREASING OVER THE WRN GULF OF MEXICO. HOWEVER..GIVEN AN EXISTING
SURFACE RIDGE EXTENDING SWWD INTO THE CENTRAL GULF OF
MEXICO...BOUNDARY LAYER MOISTURE QUALITY WILL BE POOR.
ISENTROPIC LIFT WILL INCREASE ON THE NOSE OF A 30+ KT LOW LEVEL JET
ACROSS THE OZARKS FRI NIGHT INTO SAT MORNING...BUT NAM/NAMKF AND GFS
FORECAST SOUNDINGS INDICATE LITTLE INSTABILITY FOR
THUNDERSTORMS...ALTHOUGH RAIN WILL BE LIKELY.
WILL OPT TO NOT INTRODUCE ANY THUNDER AREAS AT THIS TIME AS THE
THREAT APPEARS TOO ISOLATED AND CLOSE TO THE VERY END OF THE DAY 3
PERIOD.
..JEWELL.. 12/08/2010
