DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1202 PM CDT SAT OCT 25 2014

VALID 261200Z - 271200Z

...NO SVR TSTM AREAS FORECAST...

...SUMMARY...
ISOLATED TO SCATTERED THUNDERSTORMS WILL OCCUR ON SUNDAY NIGHT OVER
MINNESOTA AND WISCONSIN. SMALL HAIL MAY OCCUR WITH THE STRONGEST
STORMS.

...SYNOPSIS...
AN UPPER RIDGE WILL SHIFT EWD FROM THE PLAINS TOWARD THE GREAT LAKES
WITH A BROAD AREA OF CYCLONIC FLOW ALOFT SPREADING EWD ACROSS THE
ROCKIES AND PLAINS THROUGH THE PERIOD. AT THE SURFACE...A LOW
PRESSURE TROUGH WILL EXTEND FROM SRN SK SEWD ACROSS THE NRN AND
CNTRL PLAINS. DAYTIME HEATING BENEATH COOL TEMPERATURES ALOFT
BENEATH THIS TROUGH SHOULD YIELD WIDELY-SPACED LIGHTNING STRIKES
ACROSS CNTRL ID INTO NRN WY.

MEANWHILE...A SURFACE HIGH WILL REMAIN OVER THE SERN U.S. WITH ONLY
MODEST LOW-LEVEL MOISTURE RETURN ACROSS THE SRN PLAINS INTO THE MID
MS VALLEY. SOME OF THIS NWD FLUX OF MOISTURE WILL BE RESPONSIBLE FOR
ELEVATED NOCTURNAL STORMS FROM MN INTO WI AS A SWLY LOW-LEVEL JET
INCREASES IN ADVANCE OF THE UPPER TROUGH.

...MN INTO WI AND UPPER MI...
ELEVATED INSTABILITY WILL DEVELOP SUNDAY NIGHT MAINLY FROM ERN MN
ACROSS WI ATOP A COOL/STABLE LOW-LEVEL AIR MASS. THE COMBINATION OF
LIFT FROM WARM ADVECTION AND HEIGHT FALLS ALOFT SHOULD BE SUFFICIENT
FOR A RASH OF ELEVATED STORMS. THE COOL TEMPERATURE PROFILES SFC AND
ALOFT BOTH SUGGEST SMALL HAIL WILL BE POSSIBLE AT THE GROUND.
