AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
329 AM EDT TUE APR 26 2016

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 329 AM EDT TUE APR 26 2016

...CLEARING TREND THROUGH THE DAY...

HIGH IMPACT WEATHER POTENTIAL: NONE.

PATTERN OVERVIEW: STRONG CLOSED SHORT WAVE TROUGH CONTINUES TO
DIG INTO THE SW CONUS THIS MORNING AND WILL BRING A BOUT OF SEVERE
WEATHER TO THE CENTRAL AND SRN PLAINS OVER THE NEXT DAY OR TWO.
DOWNSTREAM...LOW AMPLITUDE RIDGING NOSES UP THROUGH THE MIDWEST
FEEDING INTO WESTERLY FLOW ACROSS THE GREAT LAKES/NEW ENGLAND
REGION ALONG THE SRN FRINGE OF A DEEP CLOSED LOW OVER EASTERN
CANADA.

WITHIN THE WESTERLY FLOW...COMPACT SHORT WAVE IS ADVANCING
THROUGH THE NRN LAKES REGION EARLY THIS MORNING WITH AN ATTENDING
SFC LOW SLIPPING THROUGH SRN LOWER MICHIGAN. THIS SYSTEM PRODUCED
A COMPACT BATCH OF SHOWERS/THUNDERSTORMS THAT ROLLED THROUGH THE
REGION (MOSTLY LOWER MICHIGAN) LAST EVENING AND OVERNIGHT. BULK OF
THAT ACTIVITY HAS MOVED OFF TO THE EAST...ALTHOUGH THERE ARE SOME
LINGERING SHOWERS STRETCHING BACK THROUGH THE TIP OF THE MITT AND
INTO EASTERN UPPER MICHIGAN ALONG REMAINING DEFORMATION AXIS WHICH
RESIDES ALONG AND NORTH OF THE MID LEVEL SHORT WAVE. PRECIP
CONTINUES TO BE MIXY OR FLAT OUT -SN ACROSS EASTERN UPPER
MICHIGAN AS COOLER AIR BLEEDS IN FROM THE NORTH. IN ADDITION TO
THE PRECIP...EXTENSIVE CLOUD COVER STRETCHES BACK THROUGH THE NRN
PLAINS TO ANOTHER WEAK SHORT WAVE OVER MINNESOTA.

TODAY: LEAD SHORT WAVE AND ATTENDING SFC LOW WILL QUICKLY MOVE
EASTWARD THROUGH PENNSYLVANIA/NEW YORK THIS MORNING ALLOWING
STRONG CANADIAN HIGH PRESSURE...DRY AND COOLER AIR TO BUILD DOWN
THROUGH THE GREAT LAKES. LINGERING PRECIP ACROSS THE TIP OF THE
MITT INTO EASTERN UPPER MICHIGAN SHOULD FINALLY END SOMETIME
AROUND 8 AM...ALTHOUGH SOME ADDITIONAL LIGHT SNOW ACCUMULATION
REMAINS POSSIBLE ACROSS EASTERN UPPER MICHIGAN AS LAST BIT OF
PRECIP ROTATES THROUGH.

THEN...A GRADUAL NORTH-SOUTH CLEARING TREND WILL COMMENCE WITH
EASTERN UPPER MICHIGAN SEEING SUNSHINE LATER THIS MORNING. BUT...
IT WILL TAKE A GOOD PORTION OF THE DAY FOR CLOUD COVER TO CLEAR
OUT ACROSS NRN LOWER MICHIGAN...PARTICULARLY WITH THE
AFOREMENTIONED SECONDARY UPSTREAM WEAK WAVE SLIPPING THROUGH THE
REGION. SOME LIGHT DRIZZLE WILL ALSO BE A POSSIBILITY OVER THE
HIGHER TERRAIN OF NRN LOWER MICHIGAN THROUGH THE MORNING HOURS.
BUT EVENTUALLY...NRN LOWER MICHIGAN WILL END UP PARTLY TO MOSTLY
SUNNY BY LATER IN THE AFTERNOON.

TONIGHT...CLEAR AND FAIRLY COOL FOR LATE APRIL WITH TEMPERATURES
DROPPING INTO THE MID AND UPPER 20S.

.LONG TERM...(WEDNESDAY THROUGH MONDAY)
ISSUED AT 329 AM EDT TUE APR 26 2016

(4/27)WEDNESDAY...HIGH PRESSURE BEGINS TO BUILD INTO THE UPPER GREAT
LAKES AND PUSH THE BAROCLINIC ZONE SOUTH, AS WELL AS THE MOISTURE
ASSOCIATED WITH IT. THIS WILL PRODUCE A DRY DAY, AND MOST OF THE
NIGHT, EXCEPT UNTIL AFTER 06Z, WHEN THE SFC LOW PUSHES THE WARM
FRONT BACK NORTH, AND JUST ENOUGH TO CAUSE POPS FOR THE SOUTHWEST
COUNTIES. ALTHOUGH, THE POPS ARE SLIGHT CHANCE POPS, SO WHEN IT
COMES DOWN TO IT, WILL BE SURPRISED IF ANYTHING HAPPENS BEFORE 12Z.

(4/28)THURSDAY...AS THE SFC LOW MOVES EAST, AND THE 500 MB SHORTWAVE
TROUGH MOVES INTO THE UPPER GREAT LAKES, THIS WILL PUSH THE CHANCES
FOR RAIN A LITTLE FARTHER NORTH, BUT THE 500 MB LOW MOVES OFF TO THE
EAST OVERNIGHT, AND ALLOWS THE SFC HIGH TO REASSERT ITSELF.

EXTENDED (FRIDAY THROUGH MONDAY)...TYPICALLY A DRY FLOW, THE
HUDSON BAY HIGH THAT SETS UP, WILL BE DRY, BUT NOT WARM TO CAUSE
MAJOR FIRE CONCERNS, BUT WILL HAVE TO WATCH FOR POSSIBLE WINDY
DAYS WHICH COULD ELEVATE FIRE DANGERS THROUGH THE WEEKEND. WITH
THAT SAID, THE REX BLOCK IN THE WEST WILL SPIN OFF A SERIES OF SFC
LOWS THAT WILL PRIMARILY STAY SOUTH OF THE FORECAST AREA. THIS
WILL PRODUCE PERIODIC DAYS OF SHOWERS, PROBABLY ALONG AND SOUTH OF
M-72. TEMPERATURES ARE EXPECTED TO REMAIN BELOW NORMAL THROUGH
EARLY NEXT WEEK. SO BELOW NORMAL PRECIPITATION AND TEMPERATURES
ARE WHAT IS EXPECTED. NORMAL HIGH TEMPERATURES RANGE FROM THE
UPPER 50S IN E UPPER TO THE LOWER 60S IN N LOWER.
