DAY 4-8 CONVECTIVE OUTLOOK  
NWS STORM PREDICTION CENTER NORMAN OK
0324 AM CDT MON APR 11 2016

VALID 141200Z - 191200Z

...DISCUSSION...
STABLE CONDITIONS WILL PREVAIL OVER MOST OF THE CONUS UNTIL FRI/D5
WHEN AN UPPER TROUGH AMPLIFIES OVER THE WRN STATES AND AN OMEGA
BLOCK DEVELOPS FROM THE GREAT LAKES TO THE GULF OF MEXICO. THIS
PATTERN WILL RESULT IN A SLOW INCREASE OF LOW-LEVEL MOISTURE AND
INSTABILITY FIRST ACROSS THE HIGH PLAINS ON FRI/D5 FROM THE WRN
DAKOTAS TO W TX...THEN PERSISTING ACROSS THE SRN PLAINS THROUGH D8
AS THE WRN TROUGH BECOMES NEARLY STATIONARY ACROSS THE FOUR CORNERS
STATES. MERIDIONAL UPPER FLOW WILL SUPPORT AREAS OF SEVERE STORMS
EACH AFTERNOON...WITH MODELS SUGGESTING PERHAPS A PEAK ON SAT/D6 OR
SUN/D7 OVER THE SRN HIGH PLAINS WHEN THE STRONGEST FLOW ALOFT IS
FORECAST TO EJECT EWD. GIVEN A LIKELY NARROW/SMALL AREA OF SEVERE
POTENTIAL...PREDICTABILITY IS CURRENTLY TOO LOW FOR THIS TYPE OF
PATTERN AND AT THIS RANGE.
