THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF LAKE ERIE...LAKE
HURON AND LAKE ST CLAIR.

.DAY ONE...TODAY AND TONIGHT

THERE IS A CHANCE FOR THUNDERSTORMS AFTER MIDNIGHT AS A WARM
FRONT BEGINS TO LIFT THROUGH THE AREA. THESE STORMS ARE NOT
EXPECTED TO BE SEVERE...BUT WILL HAVE THE POTENTIAL TO PRODUCE
VERY HEAVY RAINFALL...WIND GUSTS TO 35 KNOTS...AND HALF INCH
DIAMETER HAIL. STORMS WILL MOVE FROM WEST TO EAST AT 30 KNOTS.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

THERE IS A CHANCE OF THUNDERSTORMS SATURDAY AND THUNDERSTORMS ARE
LIKELY SUNDAY. SEVERE WEATHER IS POSSIBLE BOTH DAYS BUT THE
POTENTIAL LOOKS GREATER FOR SUNDAY.

A WARM FRONT WILL LEAVE WARMER AND MORE HUMID AIR OVER LAKE HURON
AND LOWER MICHIGAN SATURDAY WHICH WILL BECOME VERY UNSTABLE OVER
LAND AREAS DURING THE AFTERNOON AND EVENING. A COLD FRONT WILL
MOVE THROUGH THE REGION TO HELP FOCUS ACTIVITY BUT IT WILL BE WEAK
WHICH WILL CAUSE SOME UNCERTAINTY ON TIMING AND COVERAGE OF
STORMS. STORMS THAT DEVELOP OVER LAND AREAS COULD MOVE OVER MARINE
AREAS THROUGHOUT THE DAY.

A STRONGER LOW PRESSURE SYSTEM IS EXPECTED SUNDAY WHICH WILL PULL
THE SATURDAY COLD FRONT BACK NORTH AS A WARM FRONT. VERY UNSTABLE
AIR IS EXPECTED TO MOVE BACK INTO LAND AREAS ALONG AND AHEAD OF
THE WARM FRONT. BOTH THE FRONT AND THE SURFACE LOW ARE EXPECTED TO
COMBINE TO MAKE THUNDERSTORMS LIKELY AND HELP ORGANIZE STORMS FOR
GREATER SEVERE WEATHER POTENTIAL OVER ALL MARINE AREAS COMPARED TO
SATURDAY.

A COOLER TEMPERATURE PATTERN WILL RETURN FOR MUCH OF NEXT WEEK
BUT ENOUGH INSTABILITY WILL BE POSSIBLE FOR THUNDERSTORMS...MAINLY
WEDNESDAY AND THURSDAY.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY AND TONIGHT.
