AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
146 AM EDT MON APR 11 2011

LATEST UPDATE...AVIATION...

.SYNOPSIS...(410 PM EDT SUN APR 10 2011)
A COLD FRONT WILL COME THROUGH THIS AREA TONIGHT ENDING OUR BRIEF
TOUCH OF SUMMER LIKE TEMPERATURES IN APRIL. SOME THUNDERSTORMS ARE
EXPECTED NEAR AND WEST OF US-131 PRIOR TO MIDNIGHT...THEN NEAR AND
SOUTH OF I-94 AFTER MIDNIGHT.

MOSTLY CLOUDY AND BREEZY CONDITIONS WILL PREVAIL MONDAY. BY TUESDAY
HIGH PRESSURE WILL BUILD IN AND BRING MOSTLY CLEAR SKIES. THE NEXT
CHANCE FOR RAIN WILL BE FRIDAY INTO SUNDAY AS ANOTHER POWERFUL
SPRING STORM MOVES THROUGH THE AREA.

&&

.SHORT TERM...(1053 PM EDT SUN APR 10 2011)
(TONIGHT THROUGH TUESDAY NIGHT)
SEVERE THREAT CONTINUES TO LOOK MINIMAL OVER SOUTHWEST LOWER AS THE
NIGHT GOES ON.  AS OF 0230Z A BROKEN LINE OF THUNDERSTORMS EXTENDED
FROM NEAR GRB TO NEAR RFD.  THERE HAS BEEN A FEW SEVERE STORMS
WITHIN THIS LINE THIS EVENING.  HOWEVER...THE AIR MASS AHEAD OF THE
ADVANCING COLD FRONT IS EXPECTED TO CONTINUE TO BECOME MORE STABLE
OVERNIGHT AS THE LINE APPROACHES SOUTHWEST LOWER MICHIGAN.  WE CAN
NOT COMPLETELY RULE OUT AN ISOLATED SEVERE STORM THROUGH ABOUT
08Z.   55 TO 60 KNOTS WINDS WILL BE OVER THE REGION AT ABOUT 3K FT
TONIGHT AND A STRONGER STORM COULD BRING DOWN DAMAGING WINDS.  AFTER
08Z THE INSTABILITY IS QUICKLY LOST AND STORM INTENSITY SHOULD
DIMINISH SIGNIFICANTLY.

ANOTHER ISSUE WITH SEVERE WEATHER IS THERE WILL NOT BE ANY FOCUSED
JET DYNAMICS OVERNIGHT.  THE RIGHT ENTRANCE REGION OF THE UPPER JET
DOES BEGIN TO MOVE OVER SW LOWER MICHIGAN TOWARD DAYBREAK...BUT BY
THEN THERE WILL BE NO INSTABILITY AND THIS WILL MOST LIKELY JUST
RESULTED IN AN INCREASED COVERAGE OF SHOWERS OVER THE SOUTHERN HALF
OF THE CWA TOWARD DAYBREAK.

AS FAR AS THE UPDATE GOES...I INCREASED MIN TEMPS BY SOME 5 TO 8
DEGREES AS THE FRONT WILL ONLY BE MAKING IT THROUGH THE CWA BY 12Z.
KEPT POPS IN THE CHANCE CATEGORY OVERNIGHT.  BEST CHANCE OF PCPN
SHOULD COME LATE AND ACROSS THE SOUTHERN CWA.  SYNOPTIC SURFACE
WINDS WILL REMAIN HEALTHY OVERNIGHT WITH GUSTS IN THE 35-40 MPH
RANGE.

PREVIOUS DISCUSSION...
WHILE WE DO GET INTO THE WRAP AROUND COLD AIR FROM THE SYSTEM MONDAY
AFTERNOON INTO TUESDAY MORNING THERE IS LITTLE IN THE WAY OF MID
LEVEL MOISTURE. SO IT IS LOOKING MORE AND MORE LIKE DRY WEATHER WILL
PREVAIL FOR MOST OF THE CWA NORTH OF INTERSTATE 94 AND EAST OF
US-131 UNTIL THE NEXT SYSTEM COMES IN ON FRIDAY.

TUESDAY SHOULD BE A VERY NICE DAY HERE IN SOUTHWEST MICHIGAN AS HIGH
PRESSURE MOVES IN WITH PLENTY OF AFTERNOON SUNSHINE. CLEAR SKIES AND
COOLER TEMPERATURES WILL PREVAIL TUESDAY NIGHT WITH THE HIGH
OVERHEAD.

&&

.LONG TERM...(410 PM EDT SUN APR 10 2011)
(WEDNESDAY THROUGH SUNDAY)
MAIN CHALLENGE IN THE LONG TERM PERTAINS TO THE CLOSED OFF LOW THAT
THE MODELS ALL AGREE WILL TAKE SHAPE OVER THE MID PORTION OF THE
COUNTRY LATE IN THE WEEK.

LOWER MICHIGAN WILL REMAIN UNDER THE INFLUENCE OF AN UPPER RIDGE AT
THE BEGINNING OF THE LONG TERM PORTION OF THE FORECAST ON WED. WE
WILL BE IN BETWEEN THE DEVELOPING LOW OVER THE ERN SEABOARD AND NEXT
SYSTEM THAT WILL BE OVER THE WRN PORTION OF THE COUNTRY. THIS WILL
BRING DRY CONDITIONS AND MILD TEMPS FOR WED.

CONDITIONS BEGIN TO BECOME A BIT MORE UNSETTLED THEN WED NIGHT AND
INTO THU AS A COLD FRONT TRIES TO DROP DOWN ACROSS THE AREA DURING
THAT PERIOD. THIS IS A NRN STREAM FRONT THAT IS CUT OFF FROM A GOOD
MOISTURE SOURCE...AND IS SHEARING OUT WITH THE UPPER SUPPORT ACROSS
CANADA. THE CHC OF PCPN IS NOT VERY GOOD WED NIGHT/THU...BUT LOW CHC
POPS REMAIN JUSTIFIED JUST ENOUGH TO LEAVE IN FOR NOW.

THE REMAINDER OF THE PERIOD WILL THEN BE IMPACTED BY THE NEXT SYSTEM
COMING IN FROM THE WEST. STRONG UPPER JET EXTENDING FROM THE BERING
SEA AND ACROSS THE PACIFIC TO THE WEST COAST WILL HELP TO DIG A
STRONG UPPER LOW ACROSS THE MIDDLE PORTION OF THE COUNTRY BY FRI.
THE DEVELOPING SFC LOW JUST SW OF THE AREA WILL HELP TO ADVECT
MOISTURE OUT OF THE GULF OF MEXICO AND INTO THE AREA. THIS SHOULD
BEGIN BY FRI MORNING...AND WILL LIKELY CONTINUE INTO SAT AS
ADDITIONAL SHORT WAVES ROTATE AROUND THE SLOW MOVING UPPER LOW.

THE MODELS INDICATE THAT THE UPPER LOW WILL THEN LIFT TO THE ENE
BY SUN AS THEY INDICATE SOME PHASING WITH A NRN STREP TROUGH WELL
NORTH INTO CANADA. NOT SURE ABOUT THIS HAPPENING YET AS MODELS TEND
TO WANT TO KICK UPPER LOWS OUT TOO QUICK. WITH THIS IN MIND...WE
WILL KEEP THE CHC OF PCPN IN THROUGH SUN. NOT OUT OF THE REALM OF
POSSIBILITIES IS A CHC FOR SOME SNOW TO MIX IN AS THE CORE OF THE
COLDER AIR ADVECTS IN. WE ARE NOT WILLING TO MENTION SNOW QUITE
YET...BUT IT IS SOMETHING TO MONITOR.

&&

.AVIATION...(146 AM EDT MON APR 11 2011)
CHALLENGE CONTINUES TO BE THUNDERSTORM CHANCES AT THE TAF SITES IN
THE NEXT FEW HOURS. A BROKEN LINE OF STORMS EXTENDS FROM NEAR
GRAYLING IN NORTHERN LOWER MICHIGAN SOUTHWEST TO NEAR GRAND HAVEN IN
WEST CENTRAL LOWER MICHIGAN. THE LINE IS SWEEPING TO THE EAST RATHER
QUICKLY AND SHOULD BE OUT OF THE AREA BY 500 AM. LINE FOR THE MOST
PART HAS SEEN A DOWNWARD TREND THE LAST HOUR OR TWO AND THEREFORE
HAVE STARTED THE 06Z TAFS OFF WITH VCTS FOR A COUPLE HOUR INTERVAL
BETWEEN 06Z AND 10Z. NOT CONFIDENT ENOUGH IN THUNDER OCCURRING AT
ANY ONE TAF SITE AT THIS POINT.

SOME MVFR CEILINGS WILL TRY TO SWEEP IN BEHIND THE FRONTAL PASSAGE
FOR MONDAY MORNING IN THE 800AM TO 200PM TIME FRAME. BEYOND THAT
EXPECTING VFR CONDITIONS.

&&

.MARINE...(410 PM EDT SUN APR 10 2011)
THE SMALL CRAFT ADVISORY CONTINUED INTO MONDAY EVENING THANKS TO THE
DEEPENING SYSTEM THAT MOVES EAST OF THE CWA BY MONDAY AFTERNOON.
THE FOG WILL CONTINUE ON THE LAKE UNTIL THE COLD AIR MOVES IN AFTER
MIDNIGHT.

&&

.HYDROLOGY...(410 PM EDT SUN APR 10 2011)
THREE RIVER POINT ADVISORIES CONTINUE TODAY... VICKSBURG MAPLE
RAPIDS AND IONIA. LITTLE IN THE WAY OF SIGNIFICANT RAINFALL IS
EXPECTED TONIGHT THE NEXT BIG RAIN EVENT WILL BE NEXT WEEKEND. THIS
WILL GIVE AREAS WITH HIGH WATER HIGH TO CONTINUE TO RECOVER.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...NONE.
LM...SMALL CRAFT ADVISORY ALL NEARSHORE ZONES THRU 06Z TUE.
