AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
348 AM EST MON FEB 18 2013

.SHORT TERM... TODAY AND TONIGHT

THICKENING HIGH CLOUDS AND INCREASING SOUTHERLY WIND IS KICKING OFF
A WARMING TREND THAT BEGAN BY HELPING LIFT EARLY MORNING TEMPS OFF
LOWS NEAR ZERO IN THE THUMB WITH READINGS WELL DOWN INTO THE TEENS
ELSEWHERE. THE CONTINUED INCREASE IN SOUTHERLY WIND WILL PLACE A
CHILL ON THE STEADY WARMING WITH GUSTS NEAR 25 MPH BY AFTERNOON, BUT
READINGS WILL BE ABOVE FREEZING ALL LOCATIONS BY MID AFTERNOON ON
THE WAY TO HIGHS IN THE UPPER 30S TO LOWER 40S.

THE ONLY CONCERN FOR PRECIPITATION TODAY WILL BE DUE TO THETA-E
ADVECTION ALOFT THAT WILL MAKE MID LEVELS OF THE WARM FRONT ACTIVE
ENOUGH TO MAINTAIN A MENTION OF FLURRIES IN THE FORECAST DURING THE
THE MORNING. THE LATEST RADAR COMPOSITE INDICATES RETURNS DEVELOPING
OVER THE MIDWEST STATES AND INTO LOWER MICHIGAN AS THE BEGINNING OF
THIS PROCESS. A MORE CONVINCING INCREASE IS EXPECTED DURING THE REST
OF THE MORNING WITH ENOUGH MOISTURE TO ERODE DRY AIR IN THE LOW
LEVELS FOR FLURRIES AND POSSIBLY A BIT OF LEGITIMATE LIGHT SNOW. THE
TRI CITIES AND NORTHERN THUMB WILL HAVE THE BEST SHOT AT ANYTHING
MORE THAN A FLURRY AS SYSTEM RELATIVE ISENTROPIC ASCENT MAXIMIZES IN
THE 850 TO 700 MB LAYER WITH SPECIFIC HUMIDITY RUNNING 2-4 G/KG.

THE MAIN SHOW FOR PRECIPITATION REMAINS SET FOR TONIGHT AS A
SUBSTANTIAL INCREASE IN MOISTURE ARRIVES FROM THE GULF ON A 50-60
KNOT LOW LEVEL JET. THE POTENTIAL FOR A MIX OF RAIN AND SNOW WILL BE
FLEETING AT THE ONSET AS ANY WET BULB COOLING IS QUICKLY OVERWHELMED
BY STRONG WARM ADVECTION AT ALL LEVELS. SURFACE TEMPERATURES ARE
EXPECTED TO REACH AT LEAST 40 ALL AREAS BY MIDNIGHT AS THE MAIN
ROUND OF RAIN SHOWERS MOVES THROUGH WITH THE LOW LEVEL MOISTURE AXIS
THAT WILL SET UP IN THE WARM SECTOR. THERE IS GOOD MODEL AGREEMENT
SUGGESTING THE SYSTEM WILL PROGRESS IN A TYPICAL FASHION IN TERMS OF
ARRIVAL TIMING OF THE COLD FRONT WITH THE MID LEVEL DRY SLOT. THIS
WILL MAKE THE TRANSITION FROM RAIN TO SNOW JUST AS PRECIP ENDS FOR
LITTLE OR NO ACCUMULATION BEFORE THE MID LEVEL DRY SLOT SHUTS THINGS
DOWN TOWARD SUNRISE TUESDAY.

&&

.LONG TERM...

OUR STORM SYSTEM LOOKS TO BE PEAKING OUT OVER THE NORTHERN GREAT
LAKES TUESDAY MORNING AS THE UPPER LEVEL PV COMPLETES THE 360 DEGREE
WRAP AROUND....WITH THE SYSTEM SLOWLY FILLING IN TUESDAY AFTERNOON.
LOOKING AT A 6 HR RISE/FALL PRESSURE COUPLET JUST UNDER 20 MB
TRAVERSING THROUGH THE GREAT LAKES REGION. EXPECTING WESTERLY WIND
GUSTS AROUND 40 MPH BEHIND THE STRONG COLD FRONT AND THROUGH THE
DAY...WITH STRONG LOW LEVEL COLD ADVECTION (10+ C DROP AT 850 MB
OVER 12 HR PERIOD). 1000 TO 850 MB LAPSE RATES SEEN CLIMBING TOWARD
9 C/KM...AND WITH THE PREFERRED 925-850 MB WIND SPEEDS OF 40 KNOTS
(PER 00Z GFS)...CONFIDENCE IS HIGH IN 35 TO 40 MPH WIND GUSTS. IF
THE LOW IS ABLE TO DEEPEN A BIT MORE JUST AFTER 12Z TUESDAY...THEN A
WIND ADVISORY MAY BE NECESSARY.

WITH THE PREVIOUSLY MENTIONED STEEP LOW LEVEL LAPSE RATES...THINK WE
WILL DO WELL WITH SNOW SHOWER ACTIVITY THROUGH THEY DAY UNDER THE
BACKDROP OF THE CYCLONIC FLOW AND LAKE ENHANCEMENT KICKING IN FROM
LAKE MICHIGAN. ONE TO TWO INCHES OF SNOW ACCUMULATION APPEARS
LIKELY...HIGHEST AMOUNTS NORTH WITH WRAP AROUND MOISTURE.

CONTINUED CHANCE OF SNOW SHOWERS TUESDAY NIGHT WITH COLD CYCLONIC
FLOW (-18 C AT 850 MB) CONTINUING...BUT LOW LEVEL WINDS ARE AT AN
UNFAVORABLE 330-340 DEGREES. HOWEVER.. WILL HAVE TO KEEP EYE OUT FOR
THE NORTHERN TIP OF THE THUMB REGION WITH POSSIBLE GOOD LOW LEVEL
CONVERGENCE SETTING UP AND VEERED NORTHERLY FLOW OVER NORTHERN LAKE
HURON.

CLOUDS AND WIND SHOULD KEEP MINS ELEVATED IN LOWER TEENS TUESDAY
NIGHT. ON THE FLIP SIDE...CLOUDS WILL HOLD MAXES DOWN ON
WEDNESDAY...AS 850 MB RH REMAINS NEAR 100 PERCENT...UNTIL VERY LATE
IN THE DAY. CLOUDS BREAKING UP JUST IN TIME TO ALLOW FOR ANOTHER
COLD NIGHT AS SURFACE HIGH/RIDGE SETTLES OVER SOUTHERN LOWER
MICHIGAN THURSDAY MORNING.

STRONG UPPER LEVEL TROUGH/ENERGY APPROACHING THE PACIFIC NORTHWEST
EARLY THIS MORNING WILL DIG SOUTH/SOUTHEAST INTO THE FOUR CORNERS
REGION ON WEDNESDAY...WITH SECOND STRONG UPPER WAVE MOVING ALONG THE
PACIFIC NORTHWEST COAST...ACTING AS A KICKER TO THE SOUTHWEST 500 MB
LOW/TROUGH. 500 MB LOW IS ACTUALLY FORECASTED TO ADVANCE NORTH INTO
THE DAKOTAS ON FRIDAY...WITH EXTENSION/TROUGH AXIS SWINGING THROUGH
GREAT LAKES REGION ON FRIDAY. STILL ENOUGH OF A MOISTURE SURGE TO
SUPPORT SOME ACCUMULATION OF SNOW...BUT PRECIPITATION PATTERN SHOULD
BE ON A DECLINE AS BEST HEIGHT FALLS MOVE INTO SOUTHEAST MANITOBA.
