   DAY 3 CONVECTIVE OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0139 AM CDT TUE APR 03 2012
   
   VALID 051200Z - 061200Z
   
   ...SYNOPSIS...
   AN UPPER LOW IS FORECAST TO MOVE EWD OUT OF THE LOWER MS VALLEY AND
   ACROSS THE CNTRL GULF COAST STATES...WITH A WEAK SURFACE LOW AND
   COLD FRONT. THE FLOW REGIME S OF THE LOW CENTER WILL FAVOR LONG
   HODOGRAPHS...AND LOW LEVEL MOISTURE AND INSTABILITY WILL POTENTIALLY
   SUPPORT STRONG TO SEVERE THUNDERSTORMS THROUGH MUCH OF THE PERIOD
   FORM ERN LA/MS INTO GA AND NRN FL.
   
   TO THE W...A LARGE UPPER TROUGH WILL SLOWLY DEVELOP EWD ACROSS THE
   CNTRL AND NRN ROCKIES. SLY FLOW WILL INCREASE ACROSS THE PLAINS
   OVERNIGHT BUT SIGNIFICANT MOISTURE RETURN IS UNLIKELY UNTIL LATER IN
   THE WEEK.
   
   ...CNTRL GULF COAST STATES...
   SUBSTANTIAL MID AND UPPER LEVEL FLOW WILL OVERSPREAD THE GULF COAST
   STATES S OF THE UPPER LOW CENTER. NUMEROUS ROUNDS OF RAIN AND STORMS
   ARE EXPECTED TO BE POSSIBLE THROUGH THE DAY 3 PERIOD...WITH SEVERE
   WINDS AND HAIL LIKELY. THIS MAY OCCUR WITH EARLY ACTIVITY...AND
   PERHAPS AFTERNOON DEVELOPMENT BEHIND IT. 
   
   THE MAIN REASON FOR NO SLIGHT RISK AT THIS TIME ARE UNKNOWNS
   REGARDING EARLY PRECIPITATION AND HOW MUCH DESTABILIZATION WILL
   OCCUR IN ITS WAKE. ALSO...WITH A RELATIVELY VEERED FLOW PATTERN
   AHEAD OF THE UPPER LOW...THE TRACK OF THE UPPER VORTICITY CENTER
   WILL DETERMINE WHERE THE SECONDARY FOCUS WILL BE FOR STORMS LATER IN
   THE DAY. A SLIGHT RISK DOES SEEM PROBABLE IN LATER OUTLOOKS...BUT
   PRECISE PLACEMENT IS CURRENTLY UNCERTAIN.
