DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1015 AM CST SUN FEB 28 2010

VALID 281630Z - 011200Z

...NO SVR TSTM AREAS FORECAST...

SCATTERED SHOWERS ARE SPREADING EASTWARD TODAY ACROSS MUCH AZ/NM IN
ASSOCIATION WITH A WELL-DEFINED UPPER TROUGH MOVING THROUGH THE
REGION. THIS ACTIVITY WILL DEVELOP EASTWARD AND INTO PARTS OF TX/OK
LATER TODAY AND TONIGHT. STEEP MID LEVEL LAPSE RATES AND COLD
TEMPERATURES ALOFT WILL LEAD TO MARGINAL INSTABILITY AND THE RISK OF
A FEW THUNDERSTORMS ACROSS A BROAD AREA OF THE SOUTHERN ROCKIES AND
SOUTHERN PLAINS. HOWEVER...LIMITED LOW LEVEL MOISTURE SUGGESTS THAT
LIGHTNING ACTIVITY WILL BE QUITE ISOLATED AND WELL BELOW SEVERE
LIMITS.
