DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1223 AM CDT FRI APR 16 2010
VALID 171200Z - 181200Z
...NO SVR TSTM AREAS FORECAST...
...SYNOPSIS...
BETWEEN AN UPPER LOW SHIFTING EWD ACROSS THE NORTHEAST AND
INCREASING TROUGHING OVER THE ERN PACIFIC AND ADJACENT W COAST
REGION...A SPLIT FLOW REGIME WILL PREVAIL ACROSS THE REST OF THE
CONUS. NRN STREAM RIDGING WILL BE STRONGEST ACROSS CENTRAL
CANADA...WHILE SRN STREAM SHORT-WAVE TROUGHING WILL AFFECT MAINLY
MEXICO AND THE GULF. IN BETWEEN -- OVER MUCH OF THE CENTRAL U.S.
AND INTO THE ROCKIES -- GENERALLY SLACK FLOW ALOFT WILL PREVAIL.
AT THE SURFACE...A COLD FRONT ASSOCIATED WITH THE NERN U.S. UPPER
LOW SHOULD CONTINUE TO PUSH OFF THE MID-ATLANTIC/CAROLINA COAST
EARLY...AND SO DESPITE A BELT OF STRONG FLOW ALOFT AROUND THE UPPER
SYSTEM...CONVECTION SHOULD REMAIN PRIMARILY OFFSHORE.
SHOWERS AND THUNDERSTORMS WILL AFFECT PARTS OF THE WRN U.S. -- BUT
SHOULD REMAIN GENERALLY WEAK AND DIURNAL IN NATURE. STORMS MAY ALSO
EVOLVE ACROSS PARTS OF TX AND EWD INTO THE LOWER MS VALLEY INVOF
TRAILING PORTIONS OF THE ERN U.S. FRONTAL SYSTEM...BUT MODEST
INSTABILITY AND GENERALLY WEAK FLOW ALOFT PRECLUDE APPRECIABLE
SEVERE THREAT.
