441 AM EDT WED SEP 10 2014

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTHEAST
MICHIGAN.

.DAY ONE...TODAY AND TONIGHT

THUNDERSTORMS WILL BE LIKELY THIS AFTERNOON INTO THIS EVENING AS
A STRONG LOW PRESSURE SYSTEM AND COLD FRONT TRACK ACROSS MICHIGAN.
SOME OF THESE STORMS MAY BE SEVERE. WHILE THE MAIN HAZARD EXPECTED
WITH THE STRONGEST STORMS WILL BE DAMAGING WIND GUSTS TO AROUND 60
MPH...AN ISOLATED TORNADO STILL CANNOT BE RULED OUT THIS AFTERNOON.
THIS WILL BE ESPECIALLY TRUE FROM THE INTERSTATE 94 CORRIDOR SOUTH
WHERE LOW LEVEL SHEAR AND INSTABILITY WILL BE THE STRONGEST.

ALSO...DESPITE AVERAGE STORM MOTION OF NEARLY 40 MPH FROM WEST TO
EAST...TORRENTIAL RAINFALL CAN BE EXPECTED WITH SOME OF THE STORMS
DUE TO THE AMOUNT OF DEEP MOISTURE THAT WILL FUNNEL INTO THE AREA
DURING THE DAY. THIS WILL LEAD TO THE POTENTIAL OF LOCALIZED FLASH
FLOODING...ESPECIALLY FROM STRONG STORMS THAT PASS THROUGH URBAN
LOCATIONS.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.

MIDLAND-BAY-HURON-SAGINAW-TUSCOLA-SANILAC-SHIAWASSEE-GENESEE-LAPEER-
441 AM EDT WED SEP 10 2014

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTHEAST
MICHIGAN.

.DAY ONE...TODAY AND TONIGHT

THERE IS A GOOD CHANCE OF THUNDERSTORMS TODAY AS A STRONG LOW
PRESSURE SYSTEM LIFTS INTO THE CENTRAL GREAT LAKES. WHILE THE
POTENTIAL FOR SEVERE WEATHER WILL BE LIMITED BY THE LACK OF
SIGNIFICANT INSTABILITY...ABUNDANT ATMOSPHERIC MOISTURE WILL AID
IN THE POTENTIAL VERY HEAVY RAINFALL FROM THE STRONGEST STORMS.
THIS MAY LEAD TO LOCALIZED FLOODING DESPITE THE FACT THAT THE
STORMS WILL BE MOVING FROM WEST TO EAST AT NEAR 40 MPH. THIS FAST
STORM MOTION WILL ALSO BRING THE POTENTIAL OF WIND GUSTS TO 40 TO
50 MPH WITH A FEW OF THE STRONGEST STORMS.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT ANTICIPATED AT THIS TIME. HOWEVER...ANY
RAINFALL REPORTS WOULD BE GREATLY APPRECIATED.
