DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0742 AM CDT THU MAY 03 2012

VALID 031300Z - 041200Z

...THERE IS A SLGT RISK OF SVR TSTMS FROM THE CENTRAL PLAINS INTO
THE UPPER MS VALLEY AND GREAT LAKES REGION...

A LONG FETCH OF WEST-NORTHWEST FLOW ALOFT EXTENDS FROM THE
CENTRAL/NORTHERN ROCKIES ACROSS THE NORTHERN PLAINS AND INTO THE
GREAT LAKES REGION TODAY. THE PRIMARY BAROCLINIC ZONE EXTENDS
ROUGHLY FROM NEB INTO LOWER MI...BUT ITS EXACT PLACEMENT IS COMPLEX
DUE TO SEVERAL CLUSTERS OF CONTINUING NOCTURNAL CONVECTION. THIS
BOUNDARY WILL EVENTUALLY PROVIDE THE FOCUS FOR ORGANIZED SEVERE
THUNDERSTORMS LATER TODAY FROM PARTS OF NEB/KS/MO/IA NORTHEASTWARD
ACROSS LOWER MI AND INTO PARTS OF WESTERN NY.

...UPPER MS VALLEY INTO CENTRAL PLAINS...
PRESENT INDICATIONS ARE THAT MORNING CONVECTION OVER IA/MO WILL SLOW
THE NORTHWARD RETURN OF AMPLE MOISTURE AND RESULTING DESTABILIZATION
OVER IA. NEVERTHELESS...MOST MODEL SOLUTIONS AGREE THAT THE MAIN
SURFACE FRONT WILL EVENTUALLY BECOME ESTABLISHED ACROSS NORTHERN IA
INTO CENTRAL WI BY LATE AFTERNOON. HIGH CAPE VALUES AND WEAK
CAPPING WILL PROMOTE THE DEVELOPMENT OF SCATTERED THUNDERSTORMS
ALONG THE FRONTAL ZONE. SUFFICIENT EFFECTIVE SHEAR WILL POSE A
THREAT OF SUPERCELL STORMS CAPABLE OF LARGE HAIL AND DAMAGING WINDS.
THE LOW LEVEL JET IS FORECAST TO STRENGTHEN BY EARLY EVENING...WHICH
MAY RESULT IN AN AREA WITH SOME VERY LARGE HAIL AND TORNADO
POTENTIAL OVER NORTHERN MO/SOUTHERN IA.

...CENTRAL/EASTERN GREAT LAKES REGION...
THUNDERSTORM CLUSTERS OVER SOUTHEAST MN AND WI...AS WELL AS OVER
LOWER MI...WILL LIKELY PERSIST AND TRACK EASTWARD THROUGH THE SLIGHT
RISK AREA LATE THIS AFTERNOON AND EVENING. THE STRONGEST CELLS WILL
BE CAPABLE OF HAIL AND GUSTY/DAMAGING WINDS.
