AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
347 AM EDT TUE OCT 18 2011

.SHORT TERM... TODAY

THE LARGE AND STRONG LOW PRESSURE SYSTEM THAT WAS IN PLACE OVER
NORTHERN ONTARIO FOR THE LAST FEW DAYS HAS FINALLY WEAKENED ENOUGH
TO BE DISPLACED BY THE DEVELOPMENT OF THE NEXT SYSTEM OVER THE LOWER
MISSISSIPPI VALLEY. THIS WILL PLACE SE MICHIGAN BETWEEN SYSTEMS
TODAY WITH THE MOST NOTICEABLE WEATHER CHANGE BEING LESS WIND
FOLLOWED BY AN INCREASE IN CLOUD COVER COMPARED TO YESTERDAY. THERE
IS ALSO A CHANCE OF LIGHT RAIN UP THROUGH THE DETROIT METRO AREA
DURING THE LATE AFTERNOON AS THE LEADING EDGE OF MOISTURE FROM THE
SOUTHERN SYSTEM MOVES INTO THE REGION.

OBSERVATIONS AND MODEL ANALYSIS FIELDS INDICATE A DEEPENING UPPER
LEVEL WAVE DRIVING THE LOWER MISSISSIPPI VALLEY SYSTEM DURING THE
EARLY MORNING HOURS. SURFACE PRESSURE FALLS DOWNSTREAM OF THE UPPER
WAVE IS HELPING FORM A WARM FRONT IN THE TENNESSEE VALLEY WITH LOW
TO MID LEVEL MOISTURE TRANSPORT SUPPORTING SHOWERS AND THUNDERSTORMS
ALONG AND TO THE NORTH OF THE SURFACE FRONT AS FAR NORTH AS
INDIANAPOLIS AT PRESS TIME. THE 00Z MODELS ALL HAVE A GOOD HANDLE ON
THE SCENARIO AND ALL SHOW CYCLOGENESIS CONTINUING FROM THE GULF
COAST TO THE TENNESSEE VALLEY TODAY. THE DEEPENING LOW PRESSURE WILL
THEN ACCELERATE FGEN FORCING ALONG AND NORTH OF THE WARM FRONT WITH
BACKING UPPER LEVEL FLOW DIRECTING MOISTURE TRANSPORT/ISENTROPIC
LIFT INTO SE MICHIGAN DURING THE MID AFTERNOON INTO THIS EVENING.

&&

.LONG TERM...TONIGHT THROUGH MONDAY

TONIGHT. PRECIPITATION WILL SPRINGBOARD NORTHWARD DIRECTLY UP THE
CENTER OF LOWER MICHIGAN THIS EVENING IN RESPONSE TO AN INBOUND
MIDLEVEL JET STREAK. FORCING WILL BE MAXIMIZED ON THE NOSE AND THE
WESTERN FLANK OF THE JET CORE. ADDED COMPONENT OF MIDLEVEL
ISENTROPIC LIFT WILL ARISE AS AGEOSTROPHIC RESPONSE INCREASES IN THE
BAROCLINIC CENTER OF EASTERN ILLINOIS/WESTERN INDIANA AND CAUSES
MIDLEVEL WIND DIRECTIONS TO BACK SOUTHEASTERLY (ELEVATED FRONT
ARRIVES) BETWEEN 06-12Z. GENERALLY...FORCING PINNED TO 750-700MB
WITH LOW STATIC STABILITY ALOFT. THE UPPER LIMIT TO QPF POTENTIAL
TONIGHT APPEARS TO BE UP TO .50 INCH ALONG THE WESTERN CWA BORDER
NORTH TO THE FLINT AREA.

WEDNESDAY. A SIGNIFICANT PV ANOMALY WILL EMERGE OUT OF THE TROUGH
BASE ALONG WITH A +140KT JET STREAK. THIS WILL CAUSE SIGNIFICANT
1000-500MB GEOPOTENTIAL HEIGHT FALLS WITH THE SURFACE LOW DEEPENING
SOME 6-8 MB IN 12HRS AS THE CENTER LIFTS FROM CINCY 12Z TO FAR NW
OHIO AT 00Z. AS MANY AS TWO SEPARATE 850-700MB SPOKES
FGEN/DEFORMATION ARE EXPECTED TO EMANATE FROM LEFT EXIT QUADRANT
DIRECTLY THROUGH SOUTHEASTERN MICHIGAN....STRONGEST ARRIVING BETWEEN
21-00Z. A TREMENDOUS AMOUNT OF DYNAMICS...ALTHOUGH ANY TROPICAL
CONNECTION WILL BE LACKING. THE UPPER LIMIT TO QPF POTENTIAL DURING
THE WEDNESDAY PERIOD APPEARS TO BE BETWEEN .75-1.00 INCH CWA WIDE
SANS NORTHERN TRI CITIES AREA. HIGHS WEDNESDAY SHOULD PUSH INTO THE
LOWER TO MIDDLE 50S.

WEDNESDAY NIGHT. CONSENSUS OF MODEL DATA SUGGESTS THE SYSTEM MAY
STALL OUT FOR ROUGHLY A 6 HR PERIOD WEDNESDAY NIGHT AS THE FEATURES
TEMPORARILY STACK. THE MID TO UPPER LEVEL CLOSED LOW CENTER IS
EXPECTED TO BE OVER PORTIONS OF IL/OH/KENTUCKY. THIS PLACES
SOUTHEASTERN MICHIGAN DIRECTLY IN THE PIVOT POINT AND EXACTLY WHERE
THE ATLANTIC/TROPICAL MIDLEVEL FEED WILL HAVE THE POSSIBILITY OF
BECOMING ESTABLISHED. EXACTLY HOW OR IF THE GOMEX MOISTURE BECOMES
WRAPPED UP INTO THE LARGE MIDWESTERN BAROCLINIC SYSTEM REMAINS TO BE
SEEN. THE GFS IS SUGGESTING THAT MAIN SLUG OF MOISTURE COULD BE
SHUNTED EASTWARD BY THE RIGHT EXIT REGION DYNAMICS OF THE UPPER
LEVEL JET ON WEDNESDAY. THIS IS ONE POINT THAT NEEDS TO BE
DETERMINED. FOR QPF GRIDS DID ACCOUNT FOR TROPICAL/PWATS OF GREATER
THAN 1.25 INCHES. ASSUMING TROPICAL/ATLANTIC FEED THE UPPER LIMIT TO
QPF POTENTIAL WEDNESDAY NIGHT COULD RANGE AS MUCH AS 1 TO 2 INCHES.
AN IMPORTANT NOTE...DID COME DOWN WITH POPS A BIT FOR FAR SOUTHERN
CWA AS THE POTENTIAL EXISTS A DRY SLOT COULD LIFT INTO LAKE ERIE.

THURSDAY. SYSTEM WILL BE COMPLETELY OCCLUDED WITH FORCING LIMITED TO
A LINGERING DEFORMATION ZONE. A PERSISTENT NORTHEASTERLY FEED SHOULD
KEEP A CATEGORICAL RAIN POSSIBILITY INTO THE CWA UNTIL 00Z FRIDAY.
THE UPPER LIMIT TO QPF POTENTIAL APPEARS .10-.30 INCH...HIGH AMOUNTS
MORE LIKELY IN THE THUMB REGION. HIGHS THURSDAY STILL RELATIVELY
MILD AROUND 50 TO LOWER 50S.

FRIDAY NIGHT. MIDLEVEL WIND DIRECTIONS IN ALL MODEL SOLUTIONS MAKE A
CONCERTED MOVE TO THE NORTHWEST. THIS SIGNIFIES THE LOGICAL END TO
WHAT WILL BE A VERY WET PERIOD. CAA SHOULD PUSH TEMPS INTO THE 30S
BUT STRONG NORTHERLY WINDS WILL KEEP VALUES FROM PLUMMETING.

&&

.MARINE...

LAKE HURON AND LOWER MICHIGAN WILL BE IN BETWEEN SYSTEMS TODAY
THROUGH TONIGHT WITH LIGHTER WIND AND IMPROVED WAVE CONDITIONS. THIS
WILL BE FOLLOWED QUICKLY BY THE NEXT STRONG LOW PRESSURE SYSTEM THAT
WILL BE GATHERING FROM THE GULF COAST INTO THE OHIO VALLEY THROUGH
WEDNESDAY MORNING. STORM AND GALE WATCHES HAVE BEEN ISSUED WITH THIS
FORECAST PACKAGE AS THE SYSTEM IS EXPECTED TO DEEPEN CONSIDERABLY AS
IT APPROACHES TOLEDO BY WEDNESDAY EVENING. STORM FORCE WIND GUSTS
WILL BE POSSIBLE ON THE NORTH HALF OF LAKE HURON LATE WEDNESDAY INTO
EARLY THURSDAY WITH A STRONG GALE POSSIBLE OVER SOUTH SECTIONS
THROUGH SAGINAW BAY. LOW VISIBILITY IN HEAVY RAINFALL WILL ALSO BE A
CONCERN OVER ALL MARINE AREAS. THE TRACK OF THE SURFACE LOW FROM
ABOUT TOLEDO TO WINDSOR TO TORONTO IS EXPECTED TO RESULT IN WINDS
BELOW GALE FORCE FOR LAKE ST CLAIR AND WESTERN LAKE ERIE. THE STRONG
WIND CONDITIONS ARE THEN EXPECTED TO IMPROVE THURSDAY NIGHT INTO
FRIDAY AS THIS LOW PRESSURE SYSTEM TRACKS INTO QUEBEC.

//DISCUSSION...

VFR CONDITIONS ARE EXPECTED MUCH...IF NOT ALL...OF THIS FORECAST AS
LOWER CIGS/SHOWERS HOLD OFF UNTIL THE VERY END OF THE PERIOD AND
BEYOND AS A WEAK LOW PRESSURE SYSTEM LIFTS INTO THE OHIO VALLEY.
SOUTHWEST WINDS DURING THE MORNING WILL BECOMING LIGHT/VARIABLE
AND THEN NORTHEAST AS THIS LOW LIFTS TO NEAR LAKE ERIE. CIGS WILL
THICKEN AND LOWER DURING THE LAST PART OF THE FORECAST...BUT WILL
MAINTAIN VFR ATTM...AND LIMIT INITIAL LIGHT RAIN MENTION FROM PTK
SOUTH.
