AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
326 AM EST FRI FEB 13 2015

.SHORT TERM...TODAY AND TONIGHT

COLD AND VERY DRY AIRMASS IN PLACE OVER SOUTHEAST MICHIGAN...AS THE
00Z DTX RAOB CAME IN WITH AN 850 MB TEMP OF -21 C AND PW VALUE OF
0.07 INCHES. SURFACE TEMPERATURES (AS OF 3 AM) HAVE FALLEN INTO THE
-10 TO 5 F RANGE ACROSS SOUTHEAST MICHIGAN...AND ANOTHER 5 DEGREE
DROP SEEMS LIKELY BASED OFF CURRENT DEW PTS...CALM WINDS...AND WITH
THE CLEAR SKIES STILL INTACT. WILL HOLD ONTO THE WIND CHILL ADVISORY
ACROSS THE THUMB REGION...WHERE THE COLDEST TEMPS WILL RESIDE...AS
WINDS SHOULD ALSO KICK UP EVER SO SLIGHTLY DURING THE MORNING HOURS
AS THE SURFACE RIDGE AXIS SLIDES EAST.

WARM ADVECTION AND MOISTURE INCREASING TODAY INTO TONIGHT AHEAD OF
AN ARCTIC FRONT. THE INCREASING SOUTHWEST FLOW IS EXPECTED TO ALLOW
CLOUDS OVER WESTERN LOWER MICHIGAN TO MAKE INROADS INTO SOUTHEAST
MICHIGAN DURING THE DAY (PER RAP13)...ALONG WITH DEVELOPING
FLURRIES/LIGHT SNOW SHOWERS. MAX TEMPERATURES WILL ACTUALLY PROBABLY
BE CLOSER TO MIDNIGHT...AS INCREASING SOUTHWEST FLOW AND BOUNDARY
LAYER MIXING DEPTHS INCREASE...WITH 925 MB TEMPS ADVERTISED TO RISE
-9 C...AND WOULD EXPECT TEMPS TO MAKE IT INTO THE LOWER 20S. 925 MB
SPECIFIC HUMIDITY OF 2 G/KG SEEN STREAMING IN THIS EVENING...AND
SNOW IS EXPECTED TO DEVELOP WITH THE MOISTURE INCREASE AND LARGE
SCALE ASCENT AHEAD OF THE STRONG UPPER LEVEL PV ANOMALY DROPPING
SOUTHEAST INTO THE WESTERN GREAT LAKES...ALONG WITH CONTINUED LAKE
MICHIGAN CONTRIBUTION. LOW LEVEL CONVERGENCE/LIFT ALONG THE FRONT
WILL BE GOOD...BUT SHORT LIVED AS FRONT PLUNGES SOUTH...BUT A QUICK
INCH OR TWO OF SNOW ACCUMULATION SEEMS LIKELY...AS LOW LEVEL LAPSE
RATES WILL BECOME STEEP WITH SOME MODEST CAPE ADVERTISED PER NAM
SOUNDINGS.

&&

.LONG TERM...SATURDAY THROUGH THURSDAY

THE MID LEVEL WAVE NOW ROTATING ACROSS NORTH CENTRAL CANADA IS
FORECAST TO RAPIDLY AMPLIFY AS IT DROPS THROUGH THE GREAT LAKES
REGION ON SATURDAY. THERE IS ACTUALLY FAIRLY GOOD AGREEMENT AMONG
THE ENTIRE 00Z MODEL SUITE OF THIS SCENARIO. ANALYSIS OF THIS
FEATURE FROM A PV PROSPECTIVE SHOWS A COMPACT AND VERY DEEP POSITIVE
ANOMALY TRAVERSING SE MI EARLY SAT AFTERNOON. THE CORRESPONDING MID
LEVEL HEIGHT FALLS SHOULD INVOKE A HEALTHY RESPONSE ALONG THE ARCTIC
FRONT...FORECAST TO MOVE THROUGH SE MI SAT MORNING. WHILE THE MID
LEVEL MOISTURE IS SHOWN TO BE EAST OF THE FORECAST AREA BY 12Z
SATURDAY...THERE DOES LOOK TO BE SOME SHALLOW LOW LEVEL MOISTURE
POOLING AHEAD OF THE ARCTIC FRONT. THE NAM IS THE STRONGEST WITH
RESPECT TO THE FRONTAL FORCING IN THE SFC TO 850MB LAYER /SHOWING IT
INTENSIFYING AS THE FRONT PUSHES THROUGH THE FORECAST AREA/. GIVEN
THE DYNAMICS...THIS STRONGER SOLUTION DOES NOT SEEM UNREALISTIC.
STEEPENING LOW LEVEL LAPSE RATES ALONG THIS FRONTAL CIRCULATION WITH
TEMPS NEAR THE TOP OF THE MOIST LAYER COLD ENOUGH TO SUPPORT ICE
NUCLEI MAY LEAD TO A BRIEF PERIOD OF FAIRLY INTENSE SNOW SHOWERS SAT
MORNING. THE FRONT WILL BE PROGRESSIVE ENOUGH TO KEEP FCST SNOW
ACCUMS AN INCH OR LESS /MAINLY SOUTH OF THE I-69 CORRIDOR/.

GOOD SYSTEM RELATIVE POST FRONTAL ISENTROPIC DESCENT AND STEEPENING
LOW LEVEL LAPSE RATES DUE TO STRONG LOW LEVEL COLD AIR ADVECTION
WILL LEAD TO HIGH WINDS SAT AFTERNOON. RECENT MODEL SOUNDINGS
SUGGEST GUSTS IN THE 30-40 MPH RANGE /ALTHOUGH SOME BRIEF GUSTS NEAR
45 MPH DOES NOT LOOK OUT OF THE QUESTION/. SINCE THIS POST FRONTAL
AIRMASS WILL ORIGINATE FROM THE ARCTIC...WIND CHILLS WILL BECOME
DANGEROUSLY COLD SAT NIGHT. 925MB TEMPS ARE FORECAST TO DROP TO -28C
SAT NIGHT. EVEN WITH A GOOD GRADIENT...THIS SHOULD STILL PLUNGE
ACTUAL AIR TEMPS BELOW ZERO. THE STRONGEST WINDS WILL OCCUR SAT
AFTERNOON AND EVENING AS THERE SHOULD BE SOME TENDENCY FOR WINDS TO
WEAKEN A LITTLE OVERNIGHT AS THE BOUNDARY LAYER ATTEMPTS TO DECOUPLE
SOMEWHAT. GIVEN THE AIRMASS WILL BE SO COLD...EVEN SOME WEAKENING OF
THE WINDS SHOULD STILL CAUSE WIND CHILL READINGS TO DROP INTO THE 25
TO 35 BELOW RANGE SAT NIGHT INTO SUN MORNING. WINDS WILL WEAKEN ON
SUNDAY AS SFC HIGH PRESSURE EXPANDS ACROSS THE STATE. WITH NOT MUCH
CHANGE IN 925MB TEMPS AND VERY SHALLOW MIXING DEPTHS...ACTUALLY AIR
TEMPS MAY STRUGGLE TO RISE INTO THE SINGLE DIGITS ABOVE ZERO.

SOUTHERLY RETURN FLOW WILL ENVELOP THE AREA ON MON AS THE ARCTIC
HIGH SLIDES EAST. TEMPS HOWEVER WILL ONLY MODESTLY RISE FROM SUNDAYS
READINGS. THE LONG WAVE PATTERN OVER NOAM WILL REMAIN STRONGLY
BLOCKED THROUGH NEXT WEEK...WITH A PERSISTENT RIDGE OVER THE WEST
COAST AND DEEP TROUGHING OVER THE ERN US. A SECONDARY MID LEVEL WAVE
IS FORECAST TO DROP INTO THE GREAT LAKES REGION FROM NORTH CENTRAL
CANADA BY TUESDAY. THIS FEATURE AND ITS ASSOCIATED ARCTIC FRONT IS
NOT EXPECTED TO BE AS DYNAMIC AS THIS WEEKENDS SYSTEM...BUT WILL
BRING ANOTHER REINFORCING SHOT OF ARCTIC AIR TO SE MI WHICH WILL
LAST THROUGH THE END OF THE FORECAST PERIOD. WEAKER DYNAMIC FORCING
AND MUCH LESS MOISTURE ASSOCIATED WITH THE TUESDAY FRONTAL SYSTEM
WILL ONLY WARRANT A LOW CHANGE OF SNOW SHOWERS. OTHERWISE...THE DRY
NATURE OF THE AIRMASS WILL SUPPORT VERY LOW POPS MOST OF NEXT WORK
WEEK.

.MARINE...

SOUTHWEST WINDS WILL BE ON THE INCREASE THIS AFTERNOON AND TONIGHT
IN ADVANCE OF AN ARCTIC COLD FRONT SLOWLY PUSHING INTO THE NORTHERN
GREAT LAKES. GUSTS MAY APPROACH GALES THIS AFTERNOON AND EVENING.
THE PROBABILITY OF ANYTHING PROLONGED LOOKS LOW AND NOT ENOUGH TO
JUSTIFY A GALE WARNING FOR THIS AFTERNOON AND EVENING. THE ARCTIC
FRONT WILL MOVE ACROSS LAKE HURON LATE TONIGHT. A PUSH OF
EXCEPTIONALLY COLD AIR WILL BE MARKED BY A RAPID INCREASE IN WIND
GUSTS. GALE FORCE WIND GUSTS LOOK TO PERSIST THROUGH THE DAY
SATURDAY AND INTO SATURDAY NIGHT AS THIS ARCTIC AIR BLASTS ACROSS
THE REGION UNDER A STRONG N-NW GRADIENT. WINDS WILL THEN WEAKEN LATE
SAT NIGHT INTO SUNDAY AS ARCTIC HIGH PRESSURE OVERSPREADS THE
REGION.
