THROUGH FRIDAY. HIGH TEMPERATURES WILL ONLY REACH THE MID 60S TO MID

A FEW LIGHTER SHOWERS MAY LINGER INTO SATURDAY BUT MOST OF THE
WEEKEND SHOULD BE DRY.

&&

.SHORT TERM...(TONIGHT THROUGH SATURDAY NIGHT)
ISSUED AT 343 PM EDT THU AUG 9 2012

NO SIGNIFICANT CHANGES TO GOING FORECAST. THE BIG STORY REMAINS THE
DROUGHT EASING RAINS THROUGH SATURDAY AS SFC CYCLOGENESIS OCCURS
OVER LOWER MICHIGAN WITH LOW BECOMING VERTICALLY STACKED ACROSS
EASTERN LOWER BY FRIDAY THEN SLOWLY PULLING AWAY ON SATURDAY.
BENEFICIAL RAINS OF 1 TO 3 INCHES EXPECTED.

CONVECTION IS NOTED ACROSS WISCONSIN AND SOME STRONGER UPDRAFTS ARE
GOING UP OVER LAKE MICHIGAN AS INSTABILITY INCREASES IN AREA OF
HEIGHT FALLS IN ADVANCE ON THE ARRIVAL OF A POTENT UPPER VORT MAX.
WILL HAVE THUNDER MENTION TONIGHT AND INTO FRIDAY AS DEEPER UPDRAFTS
WILL REMAIN EMBEDDED IN THE STRATIFORM RAIN.

LOOKS LIKE THE LOW WILL HANG AROUND INTO SATURDAY...WITH IMPROVING
CONDITIONS DURING THE DAY AS IT SLOWLY LIFTS NORTHEAST AND TROWAL
AND MID LEVEL F-GEN IS REPLACED BY DRYING/SUBSIDENCE THAT FOLLOWS.

.LONG TERM...(SUNDAY THROUGH THURSDAY)
ISSUED AT 343 PM EDT THU AUG 9 2012

THE LONG TERM PERIOD WILL BE SOMEWHAT ACTIVE WITH THE UPPER LOW
MOVING OUT SUNDAY AND ANOTHER ONE MOVING IN MONDAY...THEN A STRONGER
COLD FRONT LATE IN THE WEEK.

A SFC LOW ASSOCIATED WITH THE MONDAY SHORT WAVE WILL MOVE
NORTHEASTWARD FROM THE MISSOURI VALLEY AND BRING A DECENT CHANCE OF
RAIN AND PERHAPS A FEW STORMS TO THE CWA. HIGHEST CHANCES ACROSS THE
SRN CWA. THOSE CHANCES LINGER INTO TUESDAY AS THE UPPER TROUGH MOVES
ACROSS THE CWA. WEDNESDAY LOOKS DRY AS HIGH PRESSURE BUILDS IN
BEHIND THE TROUGH. A STRONG COLD FRONT WILL APPROACH THE REGION LATE
THURSDAY. WE/LL PROBABLY SEE STORMS WITH THIS SYSTEM...HOWEVER IT/S
POSSIBLE THAT THE PCPN WON/T ARRIVE UNTIL THURSDAY NIGHT. HIGHS WILL
BE IN THE 70S SUNDAY/MONDAY AND THEN WARM INTO THE LOWER TO MID 80S
AHEAD OF THE COLD FRONT.

THE LAKE MICHIGAN SHORELINE NEAR MUSKEGON. EXPECT BY DAYBREAK THAT
MOST AREAS WILL BE RAINING ONCE AGAIN WITH IFR CEILINGS. THE IFR
