AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
400 PM EDT FRI MAY 7 2010

.SYNOPSIS.../ISSUED AT 354 PM/

A POTENT STORM SYSTEM IN THE LOWER GREAT LAKES WILL INTENSIFY AND
SLIDE UP THROUGH SOUTHEAST LOWER MICHIGAN TONIGHT...AND INTO NEW
ENGLAND BY LATE SATURDAY. THIS SYSTEM WILL BRING STRONG
THUNDERSTORMS TO LOWER MICHIGAN INTO THE OHIO VALLEY TONIGHT...AND A
TRANSITION FROM RAIN OVER TO ACCUMULATING SNOW OVERNIGHT ACROSS
NORTHERN MICHIGAN...AS SIGNIFICANTLY COLDER AIR INVADES THE REGION.

CONDITIONS ON SATURDAY WILL FEEL DOWNRIGHT FALL LIKE...WITH GUSTY
NORTHWEST WINDS...SNOW SHOWERS AND TEMPERATURES STRUGGLING TO GET
OUT OF THE 30S. BUT...HIGH PRESSURE WILL ARRIVE DURING THE LATTER
HALF OF THE WEEKEND BRINGING DRIER WEATHER AND BRIEFLY WARMER
CONDITIONS FOR MONDAY. MORE CHANCES FOR NEEDED RAIN WILL BE FOUND
INTO THE MIDDLE PORTIONS OF NEXT WEEK.

&&

.SHORT TERM.../ISSUED AT 354 PM/...TONIGHT

1004 MB SURFACE LOW REALLY TAKING SHAPE THIS AFTERNOON ACROSS
CENTRAL ILLINOIS WITH WARM ADVECTION WING OF LIGHT TO MODERATE
PRECIPITATION SPREADING NORTHWARD ACROSS NORTHERN MICHIGAN. DRY SLOT
NOTED NOW PUSHING INTO CENTRAL LOWER MICHIGAN WITH SOME CONVECTIVE
CLOUD ELEMENTS STARTING TO POP OFF. VERY TRICKY FORECAST TONIGHT
REVOLVING AROUND EVOLUTION OF RAPIDLY INTENSIFYING STORM SYSTEM
COMBINED WITH ADIABATIC COOLING LEADING TO COMPLEX PRECIP TYPE
FORECAST TONIGHT.

LATEST MODEL GUIDANCE BRINGS ELEVATED WARM LAYER (800-700MB) UP
TOWARDS THE M-68 CORRIDOR THIS EVENING. THIS LAYER IS OVER 2KFT
THICK...SO EXPECTING THINGS TO STAY MAINLY RAIN THROUGH AT LEAST 11
PM TONIGHT. FURTHER NORTH...THE MAIN QUESTION WILL BE SURROUNDING
THE SURFACE WARM LAYER WHICH WILL HOVER AROUND 2KFT THROUGH THE
EVENING HOURS. THIS IS A BIT CLOSE FOR COMFORT AND IT IS POSSIBLE WE
MAY SEE A RAIN TO SNOW CHANGEOVER FAIRLY EARLY ACROSS EASTERN UPPER
AND THE TIP OF THE MITT TONIGHT. HOWEVER...THE DRY SLOT MAY CLEAR
THINGS OUT BY MID EVENING...SO QUESTION IS...WILL THERE BE A PRECIP
THREAT TO ALLOW ANY SNOW PRIOR TO MIDNIGHT?

WELL...THERE IS CERTAINLY SOME CONCERN WITH MODELS HINTING AT SOME
MOIST ABSOLUTE INSTABILITY IN THE MID LEVELS ASSOCIATED WITH THE DRY
SLOT. THIS MAY LEAD TO SOME CONVECTIVE PRECIP DEVELOPING THIS
EVENING IN THE DRY SLOT. THESE CONVECTIVE ELEMENTS MAY PRODUCE A
QUICKER CHANGEOVER TO SNOW AS IT MAY ACT TO COOL THE COLUMN A BIT
QUICKER.

BY 09Z TOMORROW MORNING...THE LOW SHIFTS INTO SOUTHEAST ONTARIO AS
IT DEEPENS RAPIDLY TO 990 MB. THE DEFORMATION AXIS OF PRECIPITATION
ON THE NORTHWEST FLANK OF THIS SYSTEM WILL SWEEP ACROSS NORTHERN
MICHIGAN LATE TONIGHT INTO THE EARLY MORNING HOURS TOMORROW. THIS
CERTAINLY LOOKS LIKE THE BEST WINDOW OF OPPORTUNITY FOR ACCUMULATING
SNOWFALL AS SNOWFALL RATES COULD BE FAIRLY DECENT. HOWEVER...ONE
THING TO NOTE IS THAT THE BEST OMEGA LIES BENEATH THE -15C ISOTHERM
TONIGHT AND THIS MAY KEEP THE SNOWFALL ON THE WET SIDE. CONSIDERING
THE WARM GROUND THE THE TIME OF YEAR...ALL OF THIS WOULD SUGGEST
SNOWFALL RATIOS IN THE 5 TO 1 OR 8 TO 1 RANGE. WITH AROUND A HALF
INCH OF LIQUID EXPECTED TONIGHT...THIS WOULD PUT MAX SNOWFALL TOTALS
BETWEEN 3 TO 5 INCHES. HOWEVER...DO TO THE RAPID INTENSIFICATION OF
THIS SYSTEM AND GOOD DYNAMICS...IT WOULD NOT BE SURPRISING TO SEE
SOME LOCALLY HIGHER AMOUNTS UP TO 6 OR 7 INCHES. REGARDLESS...OPTING
TO PLAY IT MORE CONSERVATIVE.

AS FOR WHERE THE SNOWFALL FALLS...IT APPEARS THE BEST SNOWFALL WILL
BE INLAND FROM M-72 NORTHWARD...WHERE THE 3 TO 5 INCHES IS EXPECTED.
MEANWHILE...AMOUNTS SHOULD TRAIL OFF HEADING SOUTH WITH AN INCH OR
LESS ALONG THE M-55 CORRIDOR. WITH ALL THIS SAID...WINTER WEATHER
ADVISORIES SEEM IN ORDER FOR AREAS NORTH OF M-72 TONIGHT INTO
EASTERN UPPER MICHIGAN...EXCLUDING GRAND TRAVERSE AND LEELANAU
COUNTIES AS THE MARINE INFLUENCE MAY KEEP THINGS RAIN A BIT LONGER.

KAS

&&

.LONG TERM.../ISSUED AT 354 PM/...SATURDAY AND BEYOND

CHILLY WEATHER TO CONTINUE FOR A FEW DAYS WITH A MODERATION IN THE
PATTERN EXPECTED LATE NEXT WEEK. THERE WILL BE A COUPLE MORE CHANCES
OF RAIN AS WELL (GENERALLY TUESDAY AND FRIDAY). THE MAIN FORECAST
CONCERNS REVOLVE AROUND WRAPPING UP THE DETAILS OF THE EXITING STORM
SYSTEM SATURDAY...WIND SPEEDS AND GUSTS THROUGH SATURDAY EVENING
THEN FROST AND FREEZE POTENTIAL SATURDAY AND SUNDAY NIGHTS.

SATURDAY...WRAP AROUND MOISTURE WILL LINGER INTO SATURDAY MORNING.
THIS WILL BE MAINLY IN THE FORM OF SNOW WITH A MIXTURE OF RAIN AND
SNOW NEAR THE LAKESHORES. ADDITIONAL ACCUMULATIONS WILL BE MINOR DUE
TO THE HIGH SUN ANGLE (HECK THE SUMMER SOLSTICE IS ONLY 6 WEEKS
AWAY!). DID RUN THE WINTER WEATHER ADVISORY THROUGH 11 AM TO ACCOUNT
FOR ANY LINGERING SLIPPERY SPOTS ON AREA ROADWAYS. IT WILL THEN BE
COLD ENOUGH (LAKE/850 MB DELTA TS ABOUT 13) FOR A PERIOD OF LAKE
EFFECT SHOWERS IN THE FORM OF SNOW ACROSS THE HIGHER TERRAIN AND A
MIX ELSEWHERE.ANY OF THE SNOW ON THE GROUND WILL MELT DESPITE HIGHS
OF ONLY THE UPPER 30S TO LOWER 40S.

SATURDAY NIGHT...CLEARING SKIES AS STORM SYSTEM EXITS THE REGION AND
HIGH PRESSURE BEGINS TO BUILD IN FROM THE WEST. CHILLY AIRMASS IN
PLACE SO IF WINDS CAN DECOUPLE TEMPERATURES WOULD PLUMMET. AT THIS
TIME EXPECT MAINTENANCE OF 5 TO 10 KNOT WINDS WHICH SHOULD PRECLUDE
WIDESPREAD FREEZE BUT STILL ALLOW FOR AREAS OF FROST. LOWS GENERALLY
IN THE UPPER 20S AND LOWER 30S.

SUNDAY...CLEAR TO PARTLY CLOUDY SKIES BUT CHILLY AS SURFACE AND
UPPER LEVEL HEIGHTS CONTINUE TO BUILD. HIGHS RANGING FROM THE UPPER
40S TO LOWER 50S.

SUNDAY NIGHT...SURFACE AND UPPER LEVEL RIDGE PRETTY MUCH OVER THE
FORECAST AREA LEADING TO NEARLY CALM WINDS AND CLEAR SKIES. THIS
WILL LEAD TO NEARLY IDEAL RADIATIONAL COOLING CONDITIONS SO A
WIDESPREAD FREEZE IS A GOOD POSSIBILITY. LOWS MAINLY IN THE 20S WITH
A FEW LOWER 30S POSSIBLE NEAR THE LAKE MICHIGAN SHORELINE.

MONDAY...RIDGING FOR ANOTHER DAY LEADING TO ANOTHER CLEAR TO PARTLY
CLOUDY DAY. STILL CHILLY FOR THE SECOND WEEK OF MAY BUT MILDER THAN
RECENTLY WITH HIGHS OF WELL INTO THE 50S TO THE LOWER 60S.

TUESDAY THROUGH FRIDAY...ANOTHER COUPLE OF STORM SYSTEMS TAKE AIM AT
THE REGION BRINGING GOOD CHANCES FOR RAIN TUESDAY/TUESDAY NIGHT AND
AGAIN FRIDAY. WILL TRY TO SQUEEZE OUT DRY CONDITIONS FOR WEDNESDAY
AND THURSDAY. REMAINING COOL WITH HIGHS MAINLY IN 50S FOR TUESDAY
BUT MODERATING TEMPERATURES EXPECTED FOR WEDNESDAY THROUGH FRIDAY
WITH HIGHS MAINLY IN THE MORE SEASONABLE 60S FOR HIGHS.

SULLIVAN

&&

.MARINE.../ISSUED AT 354 PM/

WINDS WILL INCREASE LATER TONIGHT WITH THE PASSAGE OF THE SURFACE LOW
AS COLD AIR ADVECTION KICKS IN. WINDS WITH THEN CONTINUE TO BE
STRONG AND GUSTY THROUGH SATURDAY EVENING. UPGRADED GALE WATCH TO
GALE WARNING FOR NEARSHORE ZONES FROM MANISTEE AROUND TO THUNDER
BAY. ALSO ADDED LAKE HURON ZONES INTO THE GALE WARNING AS WELL AS
950 MB WINDS RAMP UP TO 35 KNOTS OR SO TOWARD MORNING WHICH SHOULD
NOT HAVE MUCH TROUBLE MIXING DOWN.

AJS

&&

.AVIATION.../ISSUED AT 232 PM/...VALID FOR 18Z TAFS

ACTIVE WEATHER PATTERN OVER THE NEXT 24 HOURS WROUGHT FULL OF
UNCERTAINTY. POTENT MID SPRING STORM SYSTEM WINDING UP IN THE
LOWER GREAT LAKES THIS AFTERNOON AND EXPECTED TO ROCKET NORTHEAST
INTO NEW ENGLAND BY SATURDAY EVENING. SO MUCH FOR THE EASY PART.
ACROSS NORTHERN LOWER MICHIGAN...INITIAL ROUND OF COLD RAINFALL
WITH VFR CIGS WILL SWING UP THROUGH THE REGION THIS AFTERNOON...
TRAILING OFF TO SOME DRIZZLE AND IFR CONDITIONS FOR THE
EVENING. THEN...BEHIND THE DEPARTING LOW...COLDER AIR AND WRAP-
AROUND PRECIP WILL SWING THROUGH NRN LOWER MICHIGAN LATER THIS
EVENING AND OVERNIGHT. FORECAST SOUNDINGS/THERMAL PROFILES SUGGEST
PRECIP WILL CHANGE OVER TO MAINLY SNOW DURING THIS TIME WITH
ACCUMULATIONS EXPECTED...ESPECIALLY AT THE PLN TAF SITE.
