DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1244 AM CDT SAT APR 17 2010
VALID 181200Z - 191200Z
...NO SVR TSTM AREAS FORECAST...
...SYNOPSIS...
GENERALLY WEAK FLOW PATTERN ALOFT IS FORECAST ACROSS MOST OF THE
U.S. THIS PERIOD...AS AN UPPER LOW SLOWLY VACATES THE NORTHEAST AND
A SECOND LARGE LOW/TROUGH REMAINS OVER THE GULF OF AK. IN
BETWEEN...A LARGE AREA OF GENERAL LONGER-WAVE RIDGING WILL PREVAIL.
PRIMARILY DIURNAL SHOWERS AND THUNDERSTORMS ARE FORECAST OVER THE
WEST/ROCKIES...WITH CONVECTION ALSO LIKELY TO LINGER ACROSS PARTS OF
TX/LA AND VICINITY. IN THESE AREAS HOWEVER...SHEAR/INSTABILITY
COMBINATION SHOULD PROVE INSUFFICIENT FOR APPRECIABLE SEVERE
POTENTIAL.
ACROSS S FL...THE NAM SUGGESTS THAT A SURFACE LOW AND ASSOCIATED
UPPER SHORT-WAVE TROUGH MAY BRING THE POTENTIAL FOR STRONGER
CONVECTION...BUT TIMING AND LOCATION OF THESE SUBTLE FEATURES PER
GFS OUTPUT IS QUITE DIFFERENT -- WITH LITTLE IF ANY SEVERE POTENTIAL
INDICATED. THUS...WILL NOT INTRODUCE ANY SEVERE PROBABILITY ACROSS
THIS REGION ATTM.
