AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
330 PM EDT SUN SEP 12 2010
.SYNOPSIS.../ISSUED AT 327 PM/
NORTHERN MICHIGAN HAS ENJOYED MOSTLY SUNNY SKIES AND MILD
TEMPERATURES THROUGHOUT THE DAY...BUT AN AREA OF LOW PRESSURE IS
BEGINNING TO MOVE INTO THE AREA FROM WESTERN UPPER PENINSULA...WHICH
WILL GENERATE RAIN SHOWERS AND POSSIBLY EVEN STRONG THUNDERSTORMS
THIS AFTERNOON AND EARLY EVENING...AND LINGER CHANCES OF RAIN
SHOWERS MONDAY AFTERNOON.
COOLER AIR WILL FILTER INTO THE GREAT LAKES AND UPPER MIDWEST
TUESDAY AND WEDNESDAY...AS THE CANADIAN SYSTEM CONTINUES TO SLOWLY
PUSH EAST. THE COOLER AIR WILL HELP GENERATE LAKE INDUCED RAIN
SHOWERS...OVER THE WESTERN LAKE INTO THE MIDDLE OF THIS WORK WEEK.
TJL
&&
.SHORT TERM.../ISSUED AT 327 PM/...TONIGHT
A NICE LOOKING DAY (SO FAR) ACROSS THE NORTH WOODS...WITH PLENTY OF
SUNSHINE AND RATHER MILD TEMPERATURES. HOWEVER...CHANGES ARE IN
STORE AS QUICK MOVING WESTERN LAKES COLD FRONT AND LOW AMPLITUDE
IMPULSES TRAVERSING BACKSIDE OF ONTARIO CENTERED TROUGH AXIS
APPROACH THE AREA QUICKLY THIS EVENING. ABOVE FORCING ALREADY ACTING
ON A FEW HUNDRED JOULES OF SURFACE BASED CAPE OVER WESTERN UPPER
MICHIGAN...IGNITING A FEW LIGHT SHOWERS. EXPECT THIS TREND TO
CONTINUE...WITH SHOWERS...AND ISOLATED STORMS...INCREASING IN
COVERAGE ACROSS CENTRAL UPPER MICHIGAN AS ABOVE FORCING BEGINS TO
WORK IN TANDEM WITH IMPRESSIVE LEFT EXIT DYNAMICS OF QUICKLY
APPROACHING 70+ KNOT MID LEVEL JET CORE. IN ADDITION...800-1000 J/KG
OF MEAN LAYER CAPE CENTERED BELOW THE ABOVE SHOULD HELP THE CAUSE.
EXPECT THIS LINE OF SHOWERS AND STORMS TO SLIDE STEADILY
SOUTHEAST...CROSSING NORTHERN MICHIGAN THIS EVENING. WOULD EXPECT
BEST COVERAGE EARLY ON THIS EVENING AS FORCING INTERACTS WITH
LINGERING INSTABILITY. WHILE WIDESPREAD THUNDERSTORM ACTIVITY IS NOT
ANTICIPATED...WILL CLOSELY NEED TO WATCH ANY STRONGER ACTIVITY WITH
SAID MEAN LAYER CAPE PROFILES AND QUICK UPTICK IN BOTH MID LEVEL
LAPSE RATES (6.0-7.0 C/KM) AND 0-6KM BULK SHEAR MAGNITUDES (UPWARDS
OF 45-60 KNOTS). IN ADDITION...SUB 800MB DRY LAYER MAY PROMOTE
ENHANCED DOWNDRAFT POTENTIAL AS EVAPORATIONAL COOLING KICKS IN.
THUS...WHILE ORGANIZED STRONG TO SEVERE ACTIVITY IS NOT ANTICIPATED
AT THIS TIME (LACK OF DEEP LAYER MOISTURE PREVENTING MORE AGGRESSIVE
CONVECTIVE DEVELOPMENT)...ISOLATED SEVERE WEATHER CANNOT BE RULED
OUT GIVEN ABOVE PARAMETERS. WILL CONTINUE TO HIGHLIGHT THIS
POTENTIAL IN THE UPDATED RENDITION OF THE HAZARDOUS WEATHER OUTLOOK.
SHOWERS AND STORMS WILL EXIT QUICKLY LATER THIS EVENING AS THE COLD
FRONT CROSSES THROUGH THE REGION. CAA DROPS 850MB TEMPERATURE CLOSE
TO FAVORABLE FOR SOME LAKE PROCESS TO DEVELOP. HOWEVER...INVERTED-V
SIGNATURE (LACK OF LOW LEVEL MOISTURE) ON SOUNDINGS AND DRY MID
LEVELS SHOULD PREVENT MUCH...IF ANY...LAKE INFLUENCE. WILL TREND
OPTIMISTICALLY...FEATURING CLEARING SKIES AFTER MIDNIGHT. ANOTHER
MILD NIGHT...WITH READINGS BY MORNING GENERALLY IN THE 50S.
MSB

.LONG TERM.../ISSUED AT 327 PM/...MONDAY AND BEYOND
...OVERALL SEPT TREND OF COOLER THAN NORMAL TEMPS CONTINUES THIS
WEEK WITH SEVERAL SUBSTANTIAL QPF EVENTS FORESEEN HERE THRU 9/25...
PATTERN: A REX BLOCK DEVELOPS OVER AK AND THE ERN PACIFIC THIS WEEK
AND A RECONFIGURATION OF THE UPR FLOW OVR THE ATLANTIC RESULTS IN A
-NAO. WHEN A SIGNIFICANT +HGT ANOMALY DEVELOPS OVER AK...THIS ALWAYS
SENDS AN POLAR/ARCTIC SURGE SWD. MODELS/ENSEMBLES HAVE IT AND
CONFIDENCE IS INCREASING THAT ITS DELIVERED HERE NEXT FRI. THIS UPR
FLOW REGIME WILL MAINTAIN THE CENTRAL CANADIAN-ERN USA TROF...
KEEPING DAYTIME TEMPS MUCH BELOW NORMAL...ESPECIALLY TUE-THU. SOME
BRIEF TEMP RECOVERY IS POSSIBLE FRI BEFORE TEMPS PROBABLY TURN
DOWNWARD AGAIN SAT-SUN. ENSEMBLES CONTINUE TO ADVERTISE BREAK DOWN
OF THE REX BLOCK NEXT WEEKEND...W/ THE UNDERCUTTING TROF PROGRESSING
INTO THE WRN USA. BUT THEY ARE HANGING ONTO IT LONGER THAN 24 HRS
AGO. THIS WILL INDUCE HGT RISES OVR THE ERN USA...WHICH EASES THE
RECENT COOLNESS AFTER SUN THE 19TH.
POTENT COLD FRONT (CDFNT) THAT MOVES THRU TNGT USHERS IN ANOTHER
CHILLY AIR MASS THRU WED IN WNW FLOW ALOFT. UNSETTLED SHOWERY WX
DEVELOPS OVER THE SNOWBELTS AS LAKES DESTABLIZE THE BOUNDARY LAYER
(BL)...PROBABLY ENDING TUE NGT. THE ERN PAC TROF EJECTS A VORT MAX
INTO CA MON. THIS TROF INDUCES LEE CYCLOGENESIS TUE WITH LOW RIDING
ALONG THE CDFNT AND THRU THE SRN GTLKS WED NGT-THU.
QPF IS OUR OWN THRU WED GIVEN HIGHLY MESOSCALE CHARACTER.
TEMPS ARE MOS GUIDE MON-TUE AND THEN CONCENSUS MOS BLENDED W/ A
TOUCH OF MOS GUIDE TUE NGT AS MOS GUIDE APPEARS TOO COLD. HOWEVER...
MOS GUIDE MAY BE CORRECT FOR IN ANY AREAS OUTSIDE LAKE EFFECT CLD
STREAMERS. "IF" SKIES CAN REMAIN CLEAR AND WINDS LIGHT ENUF S AND E
OF GLR...THERE IS A LOW PROBABILITY FOR A TOUCH OF FROST.
MON: UNSURE OF CLD EVOLUTION BUT HAVE TO BELIEVE MON AFTN TURNS OUT
A LOT CLOUDIER THAN CURRENTLY MODELED WITHIN COLD POOL ALOFT.
BLUSTERY IN STRONG CAA. WNW WINDS GUSTS UP TO 30 KTS ALONG THE
COASTS AND INTERIOR HIGH TERRAIN OF NRN LOWER.
LAKE EFFECT MON-TUE: ENVIRONMENT FOR LAKE EFFECT (LE) DOESNT APPEAR
OVERLY POTENT. THE NAM HAS BACKED OFF ITS DEEPER MSTR FCST. ALL
MODELS ARE IN UNISON NOW THAT 850-700 MB NEVER SATURATES.
EQUILIBRIUM LEVEL IS HIGHEST MON IN CAA (AROUND 8K FT) THEN DROPS
AND LEVELS OFF TO 6500 FT MON NGT THRU TUE. EXPECT SCT SHWRS IN THE
SNOWBELTS W/ AREAS AWAY FROM THE SNOWBELTS MOSTLY CLR AT NGT AND
TURNING PARTLY-MOSTLY CLDY IN THE AFTN HOURS.
WED: HIGH PRES BUILDS IN. CLD FCST IS LOW CONFIDENCE BUT LIGHT NW
FLOW LIKELY MAINTAINS SOME LAKE CLDS. EITHER WAY BELIEVE ITS MOSTLY
CLDY W/ INCREASING MID-HIGH CLDS FROM THE W AS LOW PRES ADVANCES
THRU THE MID MS VALLEY.
WED NGT-THU: LOW PRES TRACKS THRU LOWER MI WITH HIGH CONFIDENCE.
EXACT TRACK IS LESS CERTAIN. ECMWF IS INCHING NWD W/ EACH RUN WHICH
WILL PUSH BAND OF HEAVIEST QPF FURTHER INTO NRN MI. ANY FURTHER NWD
ADJUSTMENTS AND WE MAY HAVE TO CONSIDER THUNDER FOR OUR FAR SRN
COUNTIES (M-55 CORRIDOR INTO THE SAG BAY AREA). RRQ OF
ANTICYCLONICALLY-CURVED 120 KT UPR-LVL JET SUGGESTS POTENT VERTICAL
MOTION...WITH EVEN SOME HINTS OF COUPLED-JET STRUCTURE. MODELS ARE
HINTING AT A BAND OF FGEN. ANTECEDANT DRY AIR AND MESO BRANCH OF
DESCENT ASSOCIATED WITH FGEN CIRCULATION WILL LEAD TO A SHARP
CUT-OFF TO NRN EDGE OF PCPN. THIS HAS THE POTENTIAL TO BE A
SIGNIFICANT QPF EVENT HERE FOR PART OF OUR FCST AREA (1-1.5").
WED NGT: WENT WARMER MIN TEMPS WED NGT WITH WIDESPREAD CLD COVER.
THU: CLDY AND VERY COOL W/ PERIODS OF RAIN. LOWERED HIGH TEMPS BELOW
HPC GUIDANCE.
FRI: 06Z/12Z GFS AND 00Z UKMET/ECMWF/GEM ALL HAVE ANOTHER POTENT
CDFNT ON THE DOORSTEP BY LATE AFTN. 00Z GFS WAS AN OUTLIER. SHOULD
TURN OUT PARTLY CLDY BUT A BROKEN LINE OF SCT SHWRS IN THE AFTN OR
EVNG. TEMPS COULD BE WARMER THAN CURRENTLY INDICATED IF A FAIR
AMOUNT OF SUN OCCURS.
SAT-SUN: ANOTHER SURGE OF POLAR AIR. SOME TYPE OF LOW IS OUTLOOKED
TO PASS BY TO THE S.
MODELS CONTINUE TO HIT MULTI-DAY CUMULATIVE QPF POTENTIAL HARD AND
BELIEVE THIS EVENTUALLY TRANSLATES TO A WET SYSTEM IN THE THU
TIMEFRAME WITH OTHERS TO FOLLOW. PROBABILITIES FOR 2" IN THE 6-15
DAY PERIOD ARE RESPECTABLE.
POTENTIAL DECENT QPF EVENTS: THU 9/16 AND SOMETIME MON-WED 9/20-22.
MULTI-DAY MEAN 500 MB HGTS ON CPC WEBSITE (CENTERED ON SEPT 22)
OFFER HOPE FOR EVEN SOME ABOVE NORMAL WARMTH THE 19TH-25TH W/ WRN NA
TROF AND ERN NA RDG FCST TO DEVELOP. AUTOMATED CPC 8-14 DAY OUTLOOK
IS ON BOARD...INDICATING ABOVE NORMAL TEMPS AND NEAR NORMAL PCPN.
POST MORTEM: SREF/GEFS AND USA MODELS MISSED THE HEAVIER PCPN
AMOUNTS DOWNSTATE W/ YESTERDAY'S RFALL EVENT. ECMWF/GEM HAD THE BEST
DEPICTION. A GENERAL .25 TO .5" FELL OVR NRN LOWER ALONG AND W OF
I-75. LESS THAN .25" FELL OVR THE ERN U.P. AND NE LOWER. UNLIKE WHAT
THE AMERICAN MODELS SUGGESTED...THE HEAVIEST PCPN DID NOT FALL OVR
THE ERN U.P.

KTS BUT DIMINISH THIS EVNG. WILL EXPIRE THE LAKE HURON SCA AT 03Z
...BUT THE SCA FOR NRN LAKE MI INTO THE STRAITS WILL REMAIN IN
EFFECT FOR LEFTOVER 3-4 FOOTERS. A STRONG COLD FRONT WILL CROSS THE

MON: NW WINDS GUST 20-33 KTS OVER ALL NRN MI WATERS. SCA WILL BE

IGNITE A SCATTERED LINE OF SHOWER...WITH PERHAPS A FEW
THUNDERSTORMS...ACROSS UPPER MICHIGAN. THIS NARROW LINE OF SHOWERS

SHOWER MENTION FOR THREE HOUR PERIODS. AS FOR THUNDER...NOT OVERLY
EXITED ABOUT COVERAGE OF THUNDERSTORMS GIVEN DEARTH OF OVERHEAD
MOISTURE. THUS...WILL KEEP SIMPLE CB MENTION AND WATCH RADAR TRENDS.
