AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
200 PM EDT MON APR 25 2011

.SYNOPSIS.../ISSUED AT 317 AM/

HIGH PRESSURE WILL SLIDE OFF TO THE EAST TODAY...AS A PROLONGED
PERIOD OF UNSETTLED WEATHER IS POISED TO MOVE INTO THE REGION...WITH
A SERIES OF LOW PRESSURE SYSTEMS DEVELOPING IN THE CENTRAL PLAINS.
CLOUD COVER WILL THICKEN FROM SOUTH TO NORTH TODAY...WITH INCREASING
CHANCES FOR SHOWERS AND THUNDERSTORMS TONIGHT INTO TUESDAY.

&&

.SHORT TERM.../ISSUED AT 1106 AM/...THIS AFTERNOON

THE SFC HIGH IS BEGINNING ITS SLIDE TO THE EAST. THE WARM FRONT IS
JUST NORTH OF THE OHIO RIVER WITH AN AREA OF RAIN WITH THE MOST
NORTHERN EXTENT FROM JUST SOUTH OF MKE TO BIV TO MBS. THE RAIN WILL
STAY SOUTH OF THE FORECAST AREA, AS THE RAIN STAYS ALONG THE WARM
FRONT AND IS ASSOCIATED WITH THE RRQ OF THE 500 MB JET STREAK.
MAIN CONCERN WILL BE CLOUD COVER IN OUR AREA. HIGH, THIN CIRRUS
WILL BE THE MAIN CLOUD COVER ESPECIALLY FROM M-72 NORTH. THIS WILL
GENERALLY THIN THROUGH THE DAY. SOUTH OF M-72, AN AREA OF LOWER
CLOUDS HAVE BEEN MOVING INTO THE REGION AND WILL KEEP THE SKY
CLOUDY THROUGH THE DAY. TEMPERATURES LOOK TO BE ON TRACK, SO NO
MAJOR CHANGES ARE PLANNED FOR THIS UPDATE.

JSL

&&

.LONG TERM.../ISSUED AT 317 AM/...TONIGHT AND BEYOND

SURFACE LOW CENTER WILL LIFT THRU MISSOURI AND INTO ILLINOIS
TONIGHT...PUSHING THE WARM FRONT INTO FAR SRN LWR MICHIGAN. RAIN
CHANCES WILL GRADUALLY INCREASE FROM SOUTH TO NORTH ACROSS NRN LWR
MICHIGAN TONIGHT THANKS TO STRONG ISENTROPIC ASCENT (I300) AND DEEP
MOISTURE NORTH OF THE WARM FRONT. STABILITY INDICES SUGGEST THERE IS
LITTLE CHANCE FOR THUNDER TONIGHT AS SHOWALTER INDICES REMAIN IN THE
TEENS AND 700-500 MB LAPSE RATES HOLD AROUND 5.0 C/KM. WILL REMOVE
ANY MENTION OF THUNDER...AND WILL SLIGHTLY DELAY THE ONSET OF RAIN
FROM SOUTH TO NORTH ACROSS NRN LWR MICHIGAN BASED ON LATEST NAM
MODEL TRENDS AND TIMING. LOW TEMPS TONIGHT WILL COOL BACK INTO THE
40S.

WIDESPREAD RAIN WILL SPREAD INTO OUR ENTIRE CWA ON TUESDAY AS THE
SURFACE LOW CENTER REACHES SRN LAKE MICHIGAN WITH THE WARM FRONT
THRU SRN LWR MICHIGAN. STRONG ISENTROPIC ASCENT AND DEEP MOISTURE
WILL CONTINUE TO BE THE MAIN DRIVING FORCES BEHIND WIDESPREAD
PRECIP. NAM HOLDS SUFFICIENTLY UNSTABLE AIR SOUTH OF OUR CWA ALONG
AND SOUTH OF THE WARM FRONT THRU 00Z WEDNESDAY...SO WILL REMOVED ANY
MENTION OF THUNDER THRU THIS TIME AS A RESULT. HIGH TEMPS WILL RANGE
FROM THE MID 40S IN ERN UPR MICHIGAN TO THE MID TO UPPER 50S ALONG
AND SOUTH OF M-72.

SURFACE LOW WILL THEN STALL OVER THE WRN GREAT LAKES REGION TUESDAY
NIGHT AS ANOTHER LOW DEVELOPS OVER THE LOWER MISSISSIPPI VALLEY.
ASSOCIATED WARM FRONT WILL PIVOT NORTHWARD REACHING THE STRAITS BY
12Z WEDNESDAY. THIS SHOULD FINALLY PUSH SUFFICIENTLY UNSTABLE AIR
(SHOWALTER INDICES APPROACHING ZERO) INTO NRN LWR MICHIGAN FOR
THUNDERSTORM DEVELOPMENT TUESDAY NIGHT. WILL KEEP THUNDER CHANCES
OUT OF ERN UPR MICHIGAN AS THEY WILL REMAIN TOO STABLE NORTH OF THE
WARM FRONT. OVERNIGHT LOWS WILL RANGE FROM THE UPPER 30S IN ERN UPR
MICHIGAN TO THE UPPER 40S NEAR SAGINAW BAY.

THE REST OF THE WORK WEEK...WEDNESDAY THRU FRIDAY...WILL REMAIN
QUITE ACTIVE (I.E. RAINY) AS A SECOND SURFACE LOW REACHES MICHIGAN
BY WEDNESDAY...WITH A THIRD LOW PASSING JUST SE OF MICHIGAN ON
THURSDAY. RAIN WILL FINALLY COME TO AN END EARLY FRIDAY AS HIGH
PRESSURE AND DRIER AIR BUILD INTO MICHIGAN.

&&

.MARINE.../ISSUED AT 317 AM/

WINDS/WAVES WILL REMAIN BELOW SCA CRITERIA THRU TONIGHT. WINDS WILL
THEN BEGIN TO STRENGTHEN ON TUESDAY AS LOW PRESSURE LIFTS INTO THE
WRN GREAT LAKES REGION.

&&

.AVIATION.../ISSUED AT 144 PM/...VALID FOR 18Z TAFS

HIGH PRESSURE IS MOVING OFF TO THE EAST WITH WITH LIGHT EAST
WINDS OVER THE REGION. WELL SOUTH OF THE FORECAST AREA, THE SFC
LOW AND ASSOCIATED WARM FRONT WILL START TO MOVE NORTH THROUGH THE
NIGHT. THIS WILL PUSH RAIN INTO THE REGION, BUT NOT UNTIL AFTER
09Z AS THE DRY AIR IS SLOW TO MOVE OUT OF THE TAF SITES. BETWEEN
09Z AND 12Z, THE SFC BASED INVERSION WILL BEGIN TO STRENGTHEN,
AND AS THE GRADIENT TIGHTENS, LLWS WILL BE A FACTOR AS WINDS 1000
FEET OFF THE SFC WILL BE AROUND 45 KNOTS. THE RAIN AND LOW CLOUDS
(IFR) WILL BEGIN TO MOVE INTO THE REGION STARTING AROUND 11Z AT
TVC AND MOVE NORTH THROUGH THE MORNING. THAT WILL STAY IN PLACE
THROUGH 18Z.
