AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
400 AM EDT SUN APR 3 2011

.SYNOPSIS.../ISSUED AT 400 AM/

GUSTY...AND INCREASINGLY CHILLY...NORTHWEST WINDS WILL OVERSPREAD
THE NORTHERN LAKES LATER TODAY AS INTENSIFYING LOW PRESSURE PULLS
NORTHEAST AWAY FROM THE REGION. SCATTERED SHOWERS WILL
CONTINUE...WITH EVEN A FEW RUMBLES OF THUNDER THIS MORNING ACROSS
SOUTHEAST SECTIONS OF THE AREA. THESE RAIN SHOWERS WILL BEGIN TO MIX
WITH SNOW LATER THIS AFTERNOON OVER NORTHWEST LOWER AND EASTERN
UPPER MICHIGAN...WITH PRECIPITATION QUICKLY BECOMING ALL SNOW THIS
EVENING. HOWEVER...ONLY LIGHT ACCUMULATIONS ARE EXPECTED. LINGERING
LIGHT SNOW SHOWERS WILL CONTINUE INTO TUESDAY MORNING IN FAVORED
LAKE EFFECT AREAS. A WEAK LOW PRESSURE CENTER WILL BRING ANOTHER
ROUND OF LIGHT RAIN OR SNOW LATER TUESDAY INTO WEDNESDAY MORNING. A
BRIEF BREAK OCCURS WEDNESDAY NIGHT AND THURSDAY...THE NEXT SYSTEM
ARRIVING THURSDAY NIGHT INTO FRIDAY...BRINGING A THREAT OF RAIN.

MSB

&&

.SHORT TERM.../ISSUED AT 400 AM/...TODAY

988MB SURFACE LOW JUST NW OF MKG...WITH A WARM FRONT EXTENDING SE TO
BETWEEN DTW AND TOL...AND AN INVERTED TROF JUTTING UP TOWARD WESTERN
SUPERIOR. AREAS OF LIGHT SYNOPTIC PRECIP CONTINUE TO DWINDLE...
MAINLY NEAR/NORTH OF M-32. THIS APPEARS TO BE (AND SHOULD BE) ALL
RAIN. MUCH MORE SIGNIFICANT IS THE MCS PRECIP IN CENTRAL LOWER MI.
SOME AREAS HAVE RECEIVED A SUBSTANTIAL DOUSING...2-3 INCHES PER
RADAR ESTIMATES. SHRA/TSRA ARE WELL ELEVATED THIS FAR NORTH.

SURFACE LOW WILL BE CENTERED NEAR HTL AT DAYBREAK...NEARING SUDBURY
EARLY THIS AFTERNOON...AND IN FAR WESTERN QUEBEC BY EVENING. THE
OCCLUDED FRONT WILL BE OUT OF THE AREA BY 15Z. SHRA/TSRA WILL LINGER
IN THE SE UNTIL THEN...WITH SMALL HAILERS STILL A POSSIBILITY. NAM
SHOWS A POCKET OF NEAR 1K J/KG MUCAPE NEAR TAWAS AT 12Z.

THAT WILL DO IT AS FAR AS CLOSE ENCOUNTERS WITH SPRING-LIKE WX. COLD
AIR WILL RETURN (WELL...NOT THAT IT EVER REALLY LEFT) BEHIND THE
DEPARTING LOW. NW WINDS WILL PICK UP...ESPECIALLY THIS AFTERNOON...
AS THE PRESSURE GRADIENT TIGHTENS AND THE MIXED LAYER DEEPENS. 850MB
TEMPS WILL DROP TO AROUND -6C BY SUNDOWN (NOT COLD ENOUGH FOR LAKE
EFFECT/ENHANCEMENT). THE MID LEVELS (ABOVE 750MB) WILL QUICKLY DRY
OUT...AND WITH TEMPS ENTIRELY WARMER THAN -10C UNTIL ALMOST 00Z...IT
WILL BE A CHALLENGE TO GET ANYTHING OTHER THAN SPRINKLES/FLURRIES
GOING. NAM SOUNDINGS DO PUSH MOISTURE UP TO 800MB/-9C AT 00Z...SO
PERHAPS WE CAN SQUEEZE OUT SOME MARGINAL SHSN/SHRA THEN.

WILL OBVIOUSLY BE TWEAKING THE MORNING POP/WX GRIDS TO DEAL WITH THE
ONGOING MCS. OTHERWISE...POPS WILL BE MINIMAL UNTIL THE VERY END OF
THE DAY. PLENTY OF CLOUD COVER...AND TEMPS WILL HARDLY GO ANYWHERE.
JZ

&&

.LONG TERM.../ISSUED AT 400 AM/...TONIGHT AND BEYOND

BRIEF OPPORTUNITY FOR SOME LAKE EFFECT TONIGHT/EARLY TUESDAY...AS
THE 500MB TROF AND 850MB THERMAL TROF GO THRU. A SECONDARY COLD
FRONT MAY BRING SOME INTERESTING WX LATE TUESDAY INTO TUESDAY NIGHT.
PRECIP TRENDS REMAIN THE MAIN CONCERN.

PER HPC...A NAM/ECMWF BLEND WAS THE PREFERRED SOLUTION. THIS BRINGS
OUR NEXT CHANCE FOR SYNOPTIC PRECIP IN FASTER THAN THE GFS.

TONIGHT...850MB TEMPS NOT PROGGED TO DIP QUITE AS CHILLY AS EARLIER.
WE BOTTOM OUT AT 09Z...FROM -10C ON NORTHERN LAKE MI TO -12C ON
SUPERIOR. DELTA T/S ON LAKE MI ARE ONLY IN THE LOWER MINUS TEENS...
WHICH ISN/T GREAT FOR PURE LES. MID MINUS TEENS ON SUPERIOR WILL BE
CONSIDERABLY MORE FAVORABLE...THOUGH THE NW/NNW FETCH WILL KEEP LES
WEST OF THE SAULT. INHERITED NUMEROUS -SHSN IN THE SNOWBELTS...AND
THAT/S REASONABLE (ESPECIALLY IN WESTERN CHIPPEWA)...BUT WILL EXTEND
THOSE INTO THE OVERNIGHT WHEN INSTABILITY IS GREATEST (DESPITE
MID-LEVEL DRYING). GIVEN MARGINAL INSTABILITY WHEN MOISTURE IS
PRESENT (EARLY)...AND MARGINAL MOISTURE WHEN INSTABILITY PRESENT
(LATE)...ANY ACCUMS WILL BE LIGHT...LOCALLY AN INCH OR SO. CLOUDS
WILL DECREASE OUTSIDE THE SNOWBELTS OVERNIGHT AND THE MID-LEVELS
DRY. MIN TEMPS MAINLY MID-UPPER 20S.

TUESDAY...A FLAT SURFACE RIDGE AXIS WILL CROSS LOWER MI. LAKE EFFECT
WILL FADE OUT ON LAKE MI AS WINDS BACK...AND 850MB TEMPS REBOUND TO
-5C BY MIDDAY. LAKE EFFECT WILL ALSO FADE ON SUPERIOR AS BACKING
WINDS CUT OFF THE FETCH. HOWEVER...THAT WILL BE IMMEDIATELY REPLACED
BY A SYNOPTIC PRECIP THREAT. WARMER AIR RETURNS TO UPPER MI...BUT
NOT TO NORTHERN SUPERIOR AND ADJOINING PARTS OF ONTARIO...WHERE A
COLD FRONT IS SAGGING SOUTHWARD. THE RESULTING 850-700MB FGEN IS
CONSIDERABLE...AND SHIFTS SOUTHWARD FROM FAR WESTERN ONTARIO AT 12Z
TO UPPER MI BY 00Z. THIS IS OCCURRING IN AN ENVIRONMENT OF MINIMAL
STABILITY...WITH MOIST ADIABATIC LAPSE RATES FROM THE SURFACE TO
600MB. THUS...THE RESULTING RESPONSE TO FGEN FORCING IN THE
AFTERNOON COULD BE SIGNIFICANT. EXPECT BANDED PRECIP TO DEVELOP
INTO EASTERN UPPER MI IN THE AFTERNOON...WITH LOCALLY HEALTHY
SNOWFALL RATES AT TIMES. WILL DRAW SOME 1-3 INCH ACCUMS...HIGHEST
WEST OF I-75 (FGEN IS STRONGER TO THE WEST). SOUTH OF THE STRAITS
AREA...EXPECT MINIMAL PRECIP IN THE AFTERNOON. MAX TEMPS IN THE
LOW-MID 40S NORTHERN LOWER...UPPER 30S/NEAR 40 EASTERN UPPER.

TUESDAY NIGHT...WSW-ENE ORIENTED COLD FRONT WILL CROSS EASTERN UPPER
MI IN THE EVENING...MOST OF NORTHERN LOWER OVERNIGHT. FRONT WILL BE
NEAR SAGINAW BAY BY MORNING. A WEAK (1012MB) BUBBLE HIGH WILL SETTLE
IN ALONG THE NORTH SHORE OF SUPERIOR. THE 850-700MB FGEN MAX WILL
MOVE EAST TOWARD GEORGIAN BAY BY 06Z...AND CONTINUE ON ITS WAY...
THOUGH SOME DEGREE OF FGEN FORCING WILL MIGRATE SOUTHWARD INTO
NORTHERN LOWER ALONG WITH THE FRONT. BANDED PRECIP WILL CONTINUE IN
EASTERN UPPER MI THRU MID/LATE EVENING...MOVE INTO NORTHERN LOWER MI
BY EARLY OVERNIGHT...THEN WEAKEN THRU THE EARLY MORNING HOURS. WILL
BLANKET MOST OF THE FORECAST AREA WITH LIKELY POPS. AROUND AN INCH
OF SNOW WILL WORK FROM MACKINAC/SE CHIP DOWN TO M-32...THOUGH
SNOWFALL AMOUNTS WILL STILL POTENTIALLY VARY QUITE A BIT DUE TO THE
EXPECTED BANDED NATURE OF PRECIP. THE OTHER ISSUE IS THAT AS PRECIP
MOVES SOUTH INTO NORTHERN LOWER...RAIN WILL LIKELY MIX IN...AS
ABOVE- FREEZING AIR BELOW 915MB WILL TAKE A BIT TO DISPOSE OF.
BEHIND THE FRONT...850MB TEMPS WILL RETURN TO -10C IN EASTERN UPPER
OVERNIGHT...BUT THE UNFAVORABLE NORTH FETCH SHOULD KEEP ANY
POTENTIAL LES TO THE WEST. MIN TEMPS MID 20S NORTH TO NEAR 30 SOUTH.

WEDNESDAY...COLD FRONT WILL CONTINUE TO MOVE SOUTH OF MI AND INTO
THE OHIO VALLEY. THE BUBBLE HIGH BUILDS OVERHEAD IN THE AFTERNOON.
COULD SEE A SPRINKLE OR FLURRY TO START THE MORNING IN NORTHERN
LOWER BEFORE MID LEVEL MOISTURE PULLS OUT...BUT DRIER SUB-800MB AIR
IS ALREADY STARTING TO WIN OUT...AND THAT TREND WILL CONTINUE THRU
THE DAY. SO DECREASING CLOUD COVER...ESPECIALLY TO THE NORTH
(EASTERN UPPER WILL BE MOSTLY SUNNY FOR MUCH OF THE DAY). MAX TEMPS
WILL BE MAINLY IN THE 40S...THE FAR SOUTH COULD TOUCH 50F.

JZ

REST OF THE FORECAST (WEDNESDAY NIGHT THROUGH SUNDAY)...ACTIVE
PATTERN SET FORTH BY CURRENT SYSTEM SET TO CONTINUE THROUGH THE
EXTENDED AS DISTURBANCES ROTATING OUT OF DEEPENING WESTERN TROUGH
AXIS INTERACT WITH LINGERING SOUTHERN LAKES BAROCLINIC ZONE.
SHORTWAVE RIDGE AXIS MOVING OVERHEAD STARTS THE PERIOD INNOCENT
ENOUGH...WITH DRY AND SEASONABLE WEATHER EXPECTED WEDNESDAY NIGHT
INTO THURSDAY. THINGS QUICKLY CHANGE HEADING INTO THURSDAY NIGHT AS
LEAD LOW AMPLITUDE WAVE...AND ATTENDANT SURFACE LOW...MOVE RAPIDLY
NORTHEAST INTO THE NORTHERN OHIO VALLEY. LATEST GFS/ECMWF MUCH MORE
AGGRESSIVE SPREADING PRECIPITATION NORTH INTO MUCH OF NORTHERN LOWER
MICHIGAN BY EARLY FRIDAY MORNING...CONTINUING THROUGH MUCH OF
FRIDAY...AS FAIRLY ROBUST ISENTROPIC ASCENT REGIME INTERACTS WITH
IMPRESSIVE NORTHWARD SURGING WESTERN GULF OF MEXICO MOISTURE PLUME
(PWAT VALUES SURGE TO WELL OVER AN INCH OVER THE SOUTHERN LAKES).
GIVEN RECENT FASTER TREND NOTED IN GUIDANCE AND EXPECTED SHARP
CUTOFF TO NORTHERN EXTENT OF PRECIPITATION SHIELD...WILL MAINTAIN
JUST CHANCE POP MENTION AT THIS TIME. INTERESTINGLY...WILL NEED TO
CLOSELY WATCH PRECIPITATION TYPE ALONG LEADING EDGE OF RAIN SHIELD
THURSDAY NIGHT...WITH GFS AND CRUDE ECMWF SOUNDINGS PRECARIOUSLY
CLOSE TO A RAIN/SNOW MIXTURE AT THE ONSET.

FEW CHANGES TO THE REST OF THE PERIOD...WITH RAIN COMING TO AN END
FRIDAY NIGHT. CURRENT DRY FORECAST THIS WEEKEND MAY BE IN JEOPARDY
FOR AT LEAST PART OF THE PERIOD AS NEXT WAVE PINWHEELS OUT OF THE
