LATEST UPDATE...AVIATION...

.SYNOPSIS...(454 AM EDT FRI JUL 29 2011)
WITH THE COLD FRONT PUSHING SOUTH OF INTERSTATE 80 THIS MORNING...A
LARGE HIGH PRESSURE SYSTEM FROM THE NORTHERN PLAINS WILL MOVE INTO
MICHIGAN THIS AFTERNOON AND THEN MOVE SLOWLY EAST ACROSS MICHIGAN
SATURDAY AND THEN TOWARD NEW ENGLAND ON SUNDAY. THIS WILL BRING
CLEARING SKIES TO THE AREA BY LATE MORNING AND THEN PROVIDE A WARM
AND SUNNY WEEKEND FOR ALL IN SOUTHWEST LOWER MICHIGAN.

&&

.SHORT TERM...(454 AM EDT FRI JUL 29 2011)
(TONIGHT THROUGH SUNDAY)
THE ONLY REAL ISSUE IS HOW QUICKLY DOES THE RAIN END OVER THE
SOUTHERN COUNTIES THIS MORNING. LOOKING AT THE WATER VAPOR LOOPS IT
IS CLEAR A LARGE AREA OF SUBSIDENCE IS MOVING INTO MICHIGAN FROM THE
WEST. THAT WILL CLEAR THE SKIES FROM NORTHWEST TO SOUTHEAST TODAY.
THEN WITH THE SURFACE HIGH OVERHEAD SATURDAY  EXPECT MOSTLY CLEAR
SKIES AND WARM TEMPERATURES. THE HIGH MOVES OFF TO THE EAST SUNDAY
WINDS WILL TURN TO THE SOUTH AND BRING HOT WEATHER BACK TO THE AREA.

&&

.LONG TERM...(454 AM EDT FRI JUL 29 2011)
(SUNDAY NIGHT THROUGH THURSDAY)
THERE ARE TWO SYSTEMS WE ARE WATCHING IN THE LONG TERM FORECAST.
FIRST IS THE DIGGING SHORTWAVE ASSOCIATED WITH THE EXIT REGION POLAR
JET DIVING TOWARD SOUTHERN LAKE MICHIGAN MONDAY MORNING. THAT WOULD
BRING A PERIOD OF THUNDERSTORMS TO THE AREA SUNDAY NIGHT INTO EARLY
MONDAY. THEN THERE IS ANOTHER PACIFIC SHORT WAVE IN THE FLOW THAT
RIDES OVER THE UPPER RIDGE AND HEADS EAST ACROSS SOUTHERN CANADA
WEDNESDAY INTO THURSDAY. THAT TOO COULD BRING SOME THUNDERSTORMS TO
THE AREA.

OTHER THAN THAT THE LARGE UPPER LEVEL HIGH THAT HAS DOMINATED THE
WEATHER FOR THE CONUS MOST OF THIS SUMMER WILL RETROGRADE FROM THE
EAST COAST TO MID WEST EARLY THIS COMING WEEK. THAT WILL PUT
SOUTHWEST MICHIGAN ON THE EDGE OF THE POLAR JET. WHICH IN TURN MEANS
A SYSTEM WILL MOVE THROUGH THE AREA ABOUT EVERY 36 TO 48 HOURS. WITH
THE CORE OF THE JET NORTH OF THE CANADIAN BORDER THIS COMING WEEK...
THAT MEANS ABOVE NORMAL TEMPERATURES WILL PREVAIL.

&&

.AVIATION...(724 AM EDT FRI JUL 29 2011)
THE RAIN HAS FOR THE MOST PART ENDED (WILL END IN JXN BY 13Z). AN
AREA OF LOW CEILING HAS DEVELOPED BETWEEN INTERSTATE 96 AND
INTERSTATE 94. VERTICAL MIXING CAUSED BY THE COOLER AIR ALOFT MOVING
IN WILL MIX DRY AIR ALOFT WITH THE MOIST AIR NEAR THE GROUND AND
CLEAR THE SKY. THIS SHOULD HAPPEN BTW 15Z AND 18Z.

HIGH PRESSURE AND LIGHT WINDS WILL MOVE IN TONIGHT. THERE WILL
LIKELY BE SOME FOG AGAIN TONIGHT BUT TO KEEP THE TAF SIMPLE I DID
NOT INCLUDE IT IN THESE TAFS.

&&

.MARINE...(454 AM EDT FRI JUL 29 2011)
WITH THE COLD FRONT THROUGH AND HIGH PRESSURE DOMINATING THE WEATHER
OVER THE GREAT LAKES THIS WEEKEND... WAVES WILL FOR THE MOST PART BE
1 FOOT OR LESS AND SKIES MOSTLY CLEAR FROM LATE THIS AFTERNOON INTO
SUNDAY AFTERNOON.

&&

.HYDROLOGY...(454 AM EDT FRI JUL 29 2011)
THE RAINS HAVE FOR THE MOST PART ENDED. SINCE WE HAVE FLASH FLOOD
WARNINGS OR FLOOD ADVISORIES IN EFFECT FOR JUST ABOUT ALL THE
COUNTIES WE HAD THE WATCH OUT FOR... I DROPPED THE FLOOD WATCH.
THESE OTHER PRODUCTS WILL TAKE CARE OF WHAT THREAT REMAINS. GIVEN
THE 2 TO 6 INCHES OF RAIN YESTERDAY AND 1 TO 4 INCHES THAT FELL LATE
LAST NIGHT AND THIS MORNING THERE WILL BE SOME HYDRO ISSUES FOR A AT
LEAST A FEW DAYS ANYWAY (LARGER RIVER POINTS).

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...NONE.
LM...NONE.
