NWS STORM PREDICTION CENTER NORMAN OK
1228 PM CDT FRI APR 18 2014

VALID 191200Z - 201200Z

...NO SVR TSTM AREAS FORECAST...

...SUMMARY...
ISOLATED THUNDERSTORMS ARE EXPECTED EARLY IN THE PERIOD ALONG THE
EAST COAST OF FLORIDA...AND THROUGH THE AFTERNOON OVER PARTS OF
GEORGIA AND SOUTH CAROLINA.  OTHERWISE...SCATTERED THUNDERSTORMS ARE
EXPECTED OVER PARTS OF THE CENTRAL AND SOUTHERN ROCKIES DURING THE
AFTERNOON...AND INTO THE MID MISSOURI VALLEY DURING THE OVERNIGHT
HOURS.

...SYNOPSIS...
WHILE A FAST/PROGRESSIVE BELT OF UPPER FLOW WILL CONTINUE ACROSS THE
NRN U.S. AND SRN CANADA...A SLOWER FLOW STREAM OVER THE SRN 2/3 OF
THE U.S. IS PROGGED TO PERSIST DAY 2.  TWO TROUGHS WITHIN THIS SRN
STREAM FLOW FIELD -- ONE CROSSING THE SWRN U.S./INTERMOUNTAIN REGION
AND A SECOND TRAVERSING THE SERN STATES -- WILL BE ASSOCIATED WITH
THE PRIMARY AREAS OF CONVECTIVE ACTIVITY THIS FORECAST.

OVER THE WRN STATES...SHOWERS AND STORMS ARE FORECAST TO DEVELOP
WITH A PRONOUNCED/TYPICAL DIURNAL PEAK...THOUGH SOME NOCTURNAL
INCREASE IN LOW-LEVEL SLYS ACROSS THE PLAINS MAY SUPPORT AN EWD
CONTINUATION OF CONVECTION INTO THE OVERNIGHT HOURS.

IN THE SOUTHEAST...SHOWERS AND THUNDERSTORMS INVOF AN ADVANCING COLD
FRONT ARE FORECAST TO BE MOVING ACROSS FL EARLY...BUT MAY REDEVELOP
INVOF THE UPPER LOW DURING THE AFTERNOON FROM WITHIN A LARGER AREA
OF SHOWER ACTIVITY INVOF THE UPPER LOW.  WHILE A LIMITED THREAT FOR
AN ISOLATED SEVERE STORM MAY LINGER INTO THE EARLY PORTION OF THE
DAY 2 PERIOD OVER FL...RISK DOES NOT APPEAR LARGE ENOUGH ATTM TO
INTRODUCE SEVERE PROBABILITIES.
