LATEST UPDATE...
AVIATION

.SYNOPSIS...
ISSUED AT 326 AM EDT THU MAR 20 2014

SOME AREAS WILL SEE LIGHT SNOW INTO MID MORNING...THEN IT WILL COME
TO AN END.  THE CLOUDS WILL GRADUALLY BREAK UP...LEADING TO SOME
SUNSHINE BY LATE AFTERNOON.  TEMPERATURES WILL REMAIN CHILLY WITH
HIGHS ONLY IN THE 30S.

MORE LIGHT SNOW IS EXPECTED LATE TONIGHT SOUTH OF I-96...BUT ANY
ACCUMULATION WILL BE MINOR.  THIS PRECIPITATION WILL SPREAD ACROSS
ALL OF LOWER MICHIGAN ON FRIDAY...BUT AS DAYTIME TEMPERATURES WARM
INTO THE 40S...THE PRECIPITATION WILL CHANGE TO RAIN.  COOLER AIR
RETURNS ON SATURDAY WITH MORE LIGHT SNOW POSSIBLE...MAINLY OVER
CENTRAL LOWER AND NEAR LAKE MICHIGAN.

MUCH OF THE FIRST HALF OF NEXT WEEK CONTINUES TO LOOK CHILLY...BUT
WITH VERY LITTLE PRECIPITATION....ALTHOUGH SOME LIGHT RAIN OR SNOW
WILL BE POSSIBLE ON TUESDAY.  HIGH TEMPERATURES WILL ONLY BE IN THE
UPPER 20S TO MID 30S.

&&

.SHORT TERM...(TODAY THROUGH SATURDAY)
ISSUED AT 326 AM EDT THU MAR 20 2014

A FEW SNOW SHOWERS PERSIST EARLY THIS MORNING...BEING ENHANCED
SLIGHTLY BY THE LAKE.  WITH THE LOW PULLING AWAY AND WARMING
OCCURRING ALOFT THESE SNOW SHOWERS SHOULD DWINDLE AND END BY ABOUT
14Z.  THE LOW LEVEL MOISTURE GRADUALLY WANES THROUGH THE DAY SO I
EXPECT PARTLY SUNNY SKIES BY LATE AFTERNOON.  NOT MUCH TEMP RECOVERY
TODAY WITH HIGHS OF 35 TO 40.

BY LATE TONIGHT A NORTHERN STREAM SHORT WAVE MOVES INTO THE UPPER
MIDWEST.  AHEAD OF THIS SYSTEM WE WILL SEE A SURGE OF WARM
ADVECTION.  THE MODELS HAVE A SHARPER LOOKING WARM FRONT OVER
CENTRAL INDIANA AHEAD OF THE MAIN WAVE.  WITH SOME OVER RUNNING
ACROSS THIS FRONT WE COULD BEGIN TO SEE LIGHT SNOW DEVELOP SOUTH OF
I-96 TOWARD DAYBREAK.  HAVE ADDED POPS TO COVER THIS.  HOWEVER ANY
ACCUMS WILL BE VERY LIGHT...LESS THAN A HALF INCH ON GRASSY AREAS...
SO NO IMPACTS ARE ANTICIPATED.

THE SYSTEM MOVES IN FRIDAY WITH LOW PRESSURE PROGGED TO BE NEAR AZO
BY EVENING.  MUCH STRONGER DYNAMICS ARE BEING PAINTED WITH THIS
SYSTEM ...WITH A 120 KT UPPER JET...AND A 50 KT LOW LEVEL JET.
HOWEVER MOISTURE LOOKS TO BE A LIMITING FACTOR TO ANY SUBSTANTIAL
PCPN.  INCREASED POPS ESPECIALLY FOR FRIDAY AFTERNOON AND
EVENING...BUT FEEL PCPN WILL REMAIN UNDER A QUARTER INCH.  PCPN TYPE
SHOULD BE A RAIN/SNOW MIX FRIDAY MORNING...CHANGING TO ALL RAIN BY
NOON.  THEN PERHAPS A FEW SNOW FLAKES ON THE BACKSIDE OF THE SYSTEM
TOWARD MIDNIGHT FRIDAY NIGHT.

SATURDAY LOOKS COOL AND MAINLY QUIET.  HOWEVER LINGERING LOW LEVEL
MOISTURE MAY RESULT IN A FEW SNOW SHOWERS MAINLY OVER CENTRAL LOWER
AND TOWARD LAKE MICHIGAN.

.LONG TERM...(SATURDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 326 AM EDT THU MAR 20 2014

COLD WILL RULE THE EXTENDED PERIOD WITH NO BIG STORMS BUT A CHANCE
FOR SOME LIGHT SNOW SHOWERS SATURDAY NIGHT AS CYCLONIC FLOW
ACCOMPANIES THE ARCTIC AIR INTO LOWER MICHIGAN. ANOTHER CHANCE OF
SNOW ARRIVES MONDAY NIGHT AND TUESDAY WITH THE PASSAGE OF A CLIPPER
AND SHARP UPPER TROUGH.

TEMPERATURES FROM THE MODEL BLEND WERE LOWERED SEVERAL DEGREES
MONDAY THROUGH WEDNESDAY AS H85 TEMPS IN THE MINUS 15C TO MINUS 20C
RANGE MOST OF THAT PERIOD WOULD IMPLY MAXES IN THE LOWER 20S AND
MINS IN THE SINGLE NUMBERS AND EVEN BELOW ZERO IN THE COLDER SPOTS.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z FRIDAY MORNING)

AROUND 12 KNOTS AND OCCASIONAL GUSTS TO 20 KNOTS THROUGH THIS
AFTERNOON. WINDS DECREASE THIS EVENING TO BELOW 10 KNOTS.
