AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
349 AM EST WED JAN 29 2014

.SHORT TERM...TODAY AND TONIGHT

AFTER ANOTHER COLD MORNING...TEMPERATURES WILL BEGIN A WARMING TREND
TODAY UNDER STRENGTHENING SOUTHWEST FLOW. THE WIND CHILL ADVISORY
WILL REMAIN IN PLACE THROUGH 10 AM...ALTHOUGH SLOWLY WARMING TEMPS
WILL LEAD TO A STEADY RISE IN WIND CHILL READINGS DURING THE COURSE
OF THE MORNING.

THE REGIONAL WATER VAPOR IMAGERY SHOWS A MID LEVEL SHORT WAVE
IMPULSE NOW ROTATING TO THE EAST OF LAKE SUPERIOR. THIS WAVE WILL
ADVANCE ACROSS GEORGIAN BAY THIS MORNING...WHILE AN EXTENSION OF THE
MID LEVEL PV MAX SLIDES ACROSS SRN LOWER MI EARLY THIS MORNING. THIS
BROAD REGION OF WEAK ASCENT IN ADDITION TO THE PATTERN OF LOW LEVEL
WARM AIR ADVECTION ONGOING OVER LAKE MI HAS CAUSED A SLIGHT UPTICK
IN THE RESPONSE OFF LAKE MI. THE GROWING DEPTH OF THE LOW LEVEL
INVERSION DUE TO THE ONGOING MID LEVEL WARM AIR ADVECTION IS PROVING
EFFICIENT IN DUCTING THE LAKE STRATUS INTO PORTIONS OF SE MI. UNDER
THE W-SW LOW LEVEL FLOW...THE CLOUDS SHOULD PRIMARILY IMPACT THE
I-94 CORRIDOR NORTH TO THE SAGINAW VALLEY AND THUMB. THE ONSET OF
DIURNAL INSOLATION MAY ALLOW THE CLOUDS TO EXPAND IN COVERAGE
THROUGH THE EARLY PART OF THE AFTERNOON. STRONG MID LEVEL SUBSIDENCE
WILL EXPAND ACROSS SRN MI THIS AFTERNOON...WHICH SHOULD TEMPER ANY
ADDITIONAL RESPONSE OFF LAKE MI. THIS ALONG WITH THE VERY DRY AIR
UPSTREAM OF LAKE MI SUGGESTS AN OVERALL CLEARING TREND DURING THE
COURSE OF THE AFTERNOON. OBSERVATIONS INDICATE A GOOD DEAL OF
FLURRIES/LIGHT SNOW SHOWERS OUT OF THE CLOUD DECK AS THIS COLD
AIRMASS IS LEADING TO AMPLE SUPERSATURATION WITH RESPECT TO ICE
WITHIN THE SHALLOW CLOUD LAYER. THE FLURRIES/-SN SHOULD PERSIST AS
LONG AS THE CLOUDS DO TODAY.

WHILE LOW LEVEL WARM AIR ADVECTION RAISES TEMPS INTO THE TEENS THIS
AFTERNOON...THE SOUTHWEST GRADIENT WILL SUSTAIN GUSTY WINDS TODAY.
THIS WILL HOLD WIND CHILL READINGS DOWN AROUND 0 DEGREES...SO YET
ANOTHER COLD AND BLUSTERY DAY. THE LOW LEVEL FLOW WILL BACK TO THE
SSW TONIGHT IN RESPONSE TO A DEEP UPPER LOW ROTATING INTO NRN
ONTARIO AND ASSOCIATED COLD FRONT MOVING INTO THE UPPER MS VALLEY.
THE INCREASED GRADIENT OVER SE MI WILL OFFSET MUCH NOCTURNAL
DECOUPLING EVEN WITH CLEAR SKIES. THIS IS MORE SUPPORTIVE OF THE
WARMER MET MOS WITH NIGHTTIME LOWS ONLY DIPPING DOWN TO THE UPPER
SINGLE DIGITS TO AROUND 10 ABOVE. THE WINDS WILL HOWEVER AGAIN
SUPPORT SUB ZERO WIND CHILLS...BUT NOT NEARLY AS COLD AS THE LAST
COUPLE OF NIGHTS.

&&

.LONG TERM...THURSDAY THROUGH TUESDAY

THE GOOD NEWS IS THAT TEMPERATURES WILL MODERATE DUE TO ZONAL FLOW
MEANING WE WILL HAVE A BREAK FROM WIND CHILL HEADLINES. THE BAD NEWS
IS THAT THE ZONAL FLOW WILL DIRECT A COUPLE WEATHER SYSTEMS THROUGH
THE GREAT LAKES MEANING MORE SNOW IS IN THE FORECAST. STRONG JET
CURRENTLY SEEN ON WATER VAPOR BARRELING INTO THE NW CONUS WILL
FLATTEN THE WEST COAST RIDGE WHILE THE STRONG LOW OVER EASTERN
CANADA FINALLY LIFTS NE. THIS COMBINATION WILL ALLOW THE TRANSITION
TO ZONAL FLOW OVER THE NORTHERN CONUS. THE ZONAL FLOW WILL KEEP
TEMPERATURES FAIRLY UNIFORM THROUGH THE WEEK WITH HIGHS IN THE LOW
20S AND LOWS AROUND 10-15F WITH SOME DIPS INTO THE SINGLE DIGITS
POSSIBLE.

THE BROAD AREA OF HIGH PRESSURE OVER MUCH OF THE GREAT LAKES DOWN
THROUGH THE SE CONUS WILL HOLD OVER THE AREA FOR MOST OF THURSDAY
WHILE A COMPACT LOW PRESSURE SYSTEM TRACKS ACROSS ONTARIO. THIS
SYSTEM WILL DROP A COLD FRONT THROUGH THE AREA THURSDAY NIGHT WHICH
WILL STALL OVER THE OHIO VALLEY. WITH THE LOW PULLING AWAY FROM THE
AREA TO THE NE TAKING THE BEST FORCING WITH IT...THE FRONTAL FORCING
LOOKING TO DEGRADE OVER THE AREA. TO COMPLICATE THE MATTER...THE
NOSE AND LEFT EXIT REGION OF AN APPROACHING JET WILL CREATE A
DEPRESSION IN THE PRESSURE FIELD RIDING ALONG THE FRONT. THIS
RESULTING WEAK LOW WILL RIDE ALONG THE FRONT AND OFF TO THE NE. THIS
FORCING ALONG WITH MODEST MOISTURE AMOUNTS WILL PRODUCE AN AREA OF
SNOW PASSING THROUGH THE AREA THURSDAY EVENING AND INTO THE
OVERNIGHT. NOT EXPECTING TOO MUCH WITH THE DISORGANIZATION OF THE
SYSTEM ALONG WITH POOR MOISTURE PROFILE IN THE SOUNDINGS WITH MUCH
OF THE PROFILE HOVERING AROUND THE -10C LINE. GOING WITH 1-2 INCHES
WITH THE HIGHEST AMOUNTS ACROSS NORTHERN LOCATIONS AS THE FORCING
GETS BETTER THE FURTHER NORTH YOU GO.

A POSSIBLY MORE POTENT SYSTEM IS TAKING SHAPE FRIDAY NIGHT THROUGH
SATURDAY NIGHT. UNFORTUNATELY WE ARE ONLY THREE TO FOUR DAYS OUT AND
THE MODELS ARE NOT BEING VERY COOPERATIVE. IN GENERAL A LOW
AMPLITUDE TROUGH WILL DEVELOP OVER THE WEST COAST WHICH WILL DEVELOP
A SYSTEM OVER THE CENTRAL PLAINS WHICH WILL RIDE ALONG THE STALL
FRONTAL BOUNDARY AND THROUGH SE MI. GFS DEVELOPS A BIT OF A MORE
ORGANIZE LOW PRODUCING PRECIP UP THROUGH NORTHERN MI WHILE TAKING
THE LOW NE THROUGH OHIO. THE NAM HAS MORE OF A TYPICAL SOLUTION WITH
WITH THE LOW TRACK NEARLY THE SAME BUT WITH PRECIP SLOWLY LIFTING
INTO SOUTHERN MI WITH A QUICK DROP OFF IN PRECIP SOMEWHERE THROUGH
CENTRAL MI. THE EURO IS NOW PRODUCING A MORE SHEARED OUT SYSTEM WITH
A JETLET LIFTING THROUGH IN ADVANCE OF THE SYSTEM WITH THE MAIN
SYSTEM MORE ALONG THE LINES OF THE NAM. WITH TIMING
DIFFERENCES...EURO SOONER WITH THE ONSET DUE TO THE JETLET PRODUCING
A LONGER DURATION...NAM SLIGHTLY LATER WITH THE GFS HOLDING TIL
MIDDAY SATURDAY...WENT WITH MORE OF A NAM TIMING WHILE TAKING INTO
ACCOUNT OTHER FACTORS FROM BOTH THE GFS AND EURO. WITH THE POSITION
OF THE LOW TO THE SOUTH...GOOD ISENTROPIC LIFT...A FAIR GOOD
DURATION OF TIME TO WORK WITH...THINK ABOUT 2-4 INCHES...NORTH TO
SOUTH RESPECTIVELY...IS A GOOD STARTING POINT FOR THE SYSTEM. WITH
THE BOUNDARY SO CLOSE TO SOUTEHRN MI IT WILL BE EASY FOR THE SYSTEM
TO SHIFT NORTH OR SOUTH MEANING POSSIBLY WARMER WITH SOME RAIN FOR
THE MI/OH BOARDER OR THE SYSTEM COULD DIVE SOUTH ALL TOGETHER.

&&

.MARINE...

GALES WILL PERSIST THROUGH THIS EVENING FOR MOST OF LAKE HURON AS
LOW PRESSURE DRIFTING SOUTH OVER NORTHERN ONTARIO KEEPS A TIGHT
PRESSURE GRADIENT OVER THE NORTHERN GREAT LAKES. THE WINDS WILL
RELAX SOME THIS AFTERNOON AS FLOW BACKS TO THE SOUTHWEST IN ADVANCE
OF THE NEXT SYSTEM. MOST OF THE GALES WARNINGS WILL DROP OFF AT THIS
POINT. CENTRAL LAKE HURON WILL HAVE A BRIEF LULL IN THE EVENING
BEFORE THE SOUTHWEST GRADIENT TIGHTENS BACK UP AND A DEEPER MIXING
LAYER WILL BE ABLE TO TAP INTO THE INCREASING LOW LEVEL JET AROUND
40-50 KNOTS. THIS WILL MEAN A GALE WARNING WILL AGAIN BE NEEDED FOR
SEVERAL HOURS THURSDAY MORNING. EXTENDED THE CURRENT WARNING FOR THE
CENTRAL ZONES INTO THURSDAY AFTERNOON EVEN THOUGH IT INCLUDES A
SHORT PERIOD OF NON GALES WEDNESDAY EVENING.

&&

.AVIATION...ISSUED 1212 AM EST WED JAN 29 2014/

//DISCUSSION...

SCT-BKN MVFR/LOWER VFR LAKE STRATUS WILL REMAIN IN THE VICINITY OF
KMBS OVERNIGHT THROUGH WEDNESDAY AND SAG SOUTH TOWARDS FNT/PTK AS
WIND DIRECTION VEERS TO 250-260 DEGREES. OTHERWISE...MAIN HIGHLIGHT
OF THE FORECAST WILL BE WIND GUSTS OF 25 KNOTS OR MORE WEDNESDAY AS
THE PRESSURE GRADIENT TIGHTENS ACROSS THE AREA BETWEEN HIGH PRESSURE
TO THE SOUTH AND LOW PRESSURE CROSSING NORTH OF THE GREAT LAKES. THE
WINDS WILL THEN DIMINISH TO 10-15 KNOTS BY THE END OF THE FORECAST
AS THE BOUNDARY LAYER DECOUPLES (EVEN THOUGH GRADIENT REMAINS RATHER
IMPRESSIVE).

FOR DTW...TEMPERATURE AND WIND CHILL WILL REMAIN A SERIOUS CONCERN
FOR GROUND OPERATIONS OVERNIGHT. DUE TO THE SOUTHWEST WINDS...LAKE
STRATUS WILL REMAIN NORTHWEST OF THE AREA THROUGH WEDNESDAY. THESE
WINDS WILL BECOME RATHER GUSTY (25 KNOTS OR SO) DURING BEST MIXING
WEDNESDAY.

//DTW THRESHOLD THREATS...

* MEDIUM CONFIDENCE IN WIND GUSTS TO 25 KNOTS FROM 230-240 DEGREES
FROM MID MORNING TO MID AFTERNOON WEDNESDAY.
