DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0237 PM CDT THU OCT 28 2010
VALID 282000Z - 291200Z
...NO SVR TSTM AREAS FORECAST...
FOR THE 20Z OUTLOOK...TRIMMED THE WRN EDGE OF THE THUNDER-LINE DUE
TO A COLD FRONT WHICH IS MOVING DRIER AIR SEWD ACROSS THE ERN GULF
COAST STATES AND CAROLINAS. OTHERWISE...THE FORECAST LOOKS TO BE ON
TRACK.
..BROYLES.. 10/28/2010
.PREV DISCUSSION... /ISSUED 1104 AM CDT THU OCT 28 2010/
BROAD CYCLONIC FLOW IS PRESENT TODAY OVER THE EASTERN HALF OF THE
UNITED STATES...WITH THE PRIMARY TROUGH AXIS ROTATING EASTWARD
TOWARD THE ATLANTIC SEABOARD. THE MAIN SURFACE COLD FRONT EXTENDS
FROM NC INTO GA/FL PANHANDLE AND CONTINUES TO BE THE FOCUS FOR
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS. DESPITE WEAK MID
LEVEL LAPSE RATES...POCKETS OF DAYTIME HEATING AND DEWPOINTS IN THE
70S WILL YIELD MARGINAL AFTERNOON INSTABILITY AND POSE A RISK FOR
CONTINUED THUNDERSTORMS ALONG/AHEAD OF THE FRONT ALONG THE SOUTHEAST
COAST. VERTICAL SHEAR IS WEAK AND LOW LEVEL WINDS ARE VEERED.
THEREFORE...ALTHOUGH A FEW STORMS MAY PRODUCE LOCALLY GUSTY
WINDS...ORGANIZED SEVERE STORMS ARE NOT ANTICIPATED.
