AREA FORECAST DISCUSSION

146 AM EDT MON OCT 25 2010

.AVIATION...
KSBN BEING CLIPPED BY EDGE OF SHOWERS AND STORMS THAT HAVE BEEN
ONGOING PAST FEW HOURS TO THE WEST. ONCE THESE MOVE
THROUGH...LOOKS LIKE A LULL IN THINGS MAYBE FOR THE REST OF THE
NIGHT AS SATELLITE DATA SHOWS WARMING CLOUD TOPS TO THE SW. A
SMALL AREA OF SHOWERS AND STORMS WILL MOVE IN FROM EC ILLINOIS BUT
SHOULD PASS BETWEEN BOTH TAF SITES /IF IT EVEN HOLDS TOGETHER/. IF
NEW DEVELOPMENT IS NOTED WILL AMEND AS NEEDED.

ONCE THIS SHORTWAVE EXISTS THINGS SHOULD CALM DOWN THROUGH 6Z TUES
WITH LITTLE MORE THAN SOME SCT CU AND HIGH CLOUDS. WINDS WILL PICK
UP A BIT IN THE AFTERNOON AND THEN SHIFT IN THE EVENING IN
RESPONSE TO THE DEVELOPING STORM SYSTEM TO THE SOUTHWEST.

&&

.PREV DISCUSSION... /ISSUED 440 PM EDT SUN OCT 24 2010/

DISCUSSION...

.VERY STRONG WINDS FOR TUESDAY AND WEDNESDAY...

TONIGHT THROUGH MONDAY

MAIN FORECAST CONCERNS FOR THE NEAR TERM WILL BE CHANCES OF RAIN
TONIGHT THROUGH EARLY MONDAY...AND THEN DEVELOPMENT OF POWERFUL FALL
STORM STORM THAT SYSTEM THAT WILL AFFECT THE REGION BEGINNING MONDAY
NIGHT. VERY STRONG WINDS TO ACCOMPANY THIS SYSTEM TUESDAY AND
WEDNESDAY...AND SOME TYPE OF WIND HEADLINE WILL EVENTUALLY BE
REQUIRED.

WATER VAPOR IMAGERY LATE THIS AFTERNOON INDICATING MAIN UPPER LEVEL
TROUGH AXIS SITUATED FROM SOUTHERN MINNESOTA INTO NORTHERN MISSOURI.
SEVERAL SMALLER SCALE SHORT WAVES HAVE BEEN RIPPLING THROUGH
DOWNSTREAM PORTION OF THE MAIN UPPER TROUGH ACROSS THE SOUTHERN
GREAT LAKES REGION. THE FIRST OF THESE TROUGHS LIFTED HAS LIFTED
NORTH OF THE AREA INTO SOUTHERN WISCONSIN/LOWER MICHIGAN...WHILE
ANOTHER SHEARING VORT MAX CONTINUES TO TRACK ACROSS EAST CENTRAL
INDIANA/WESTERN OHIO. SFC OBSERVATIONS HAVE BEEN INDICATING A BROAD
WEAK SFC CONVERGENCE ZONE ACROSS EAST CENTRAL INDIANA WHICH HAS BEEN
AIDING REDEVELOPMENT OF SHOWERS AND ISOLATED THUNDERSTORMS. SHOULD
GRADUALLY SEE THIS AREA OF SHOWERS SHIFT OFF TO THE EAST AS THE
AFOREMENTIONED SHORT WAVE TRACKS EAST OF THE AREA. THE INCOMING
UPPER LEVEL SHORT WAVE FROM WESTERN IOWA WILL INCREASE LARGE SCALE
LIFT ACROSS THE REGION LATE THIS AFTERNOON...WITH INSTABILITY AXIS
ALREADY IN PLACE FROM SOUTHERN MISSOURI INTO NORTHWEST INDIANA.
THUS...HAVE MAINTAINED IDEA OF LIKELY POPS EARLY THIS EVENING ACROSS
WESTERN PORTIONS OF THE AREA WITH THIS SECONDARY FAVORED AREA OF
DEVELOPMENT. DID MAINTAIN HIGH CHANCE OR LIKELY POPS FOR
SHOWERS/ISOLATED STORMS OVERNIGHT AS THIS TROUGH SLOWLY TRACKS
THROUGH THE AREA. LOWS TONIGHT WILL BE QUITE MILD GIVEN SECONDARY
LOW LEVEL THETA-E RIDGE SURGING INTO THE AREA. COULD EVEN SEE SOME
STRATUS REDEVELOP DUE TO THIS WARM/MOIST ADVECTION THAT COULD ALSO
KEEP MIN TEMPS UP.

ON MONDAY...SHOULD SEE CHANCE OF PRECIP COME TO AN END IN THE
MORNING AS MID/UPPER LEVEL HEIGHTS BEGIN TO BUILD DOWNSTREAM OF
AMPLIFYING WESTERN CONUS TROUGH. VERY STRONG UPPER LEVEL JET...200
KNOTS PLUS...ACROSS EASTERN PACIFIC WILL NOSE INTO CENTRAL ROCKIES
EARLY MONDAY WITH EXPLOSIVE CYCLOGENESIS COMMENCING. UPPER TROUGH TO
QUICKLY ACQUIRE NEGATIVE TILT AS THIS JET ROUNDS THE BASE OF THE
DEEPENING TROUGH. STRENGTHENING SOUTHERLY FLOW DOWNSTREAM WILL LIFT
LOW LEVEL WARM FRONT THROUGH THE AREA...AND HIGHS IN THE MID TO
POSSIBLY EVEN UPPER 70S WILL BE POSSIBLE MONDAY AFTERNOON.
UNSEASONABLY MILD NIGHT IN STORE FOR MONDAY NIGHT AS RAPID
CYCLOGENESIS CONTINUES ACROSS UPPER MIDWEST WITH MODELS IN GENERAL
AGREEMENT OF DEEPENING RATES ON THE ORDER OF 24 MB IN THE 24 HOUR
PERIOD ENDING FROM THE PERIOD 18Z MON TO 18Z TUE. WINDS WILL
CONTINUE TO RAMP UP MONDAY NIGHT WITH A 55 TO 70 KNOT LOW LEVEL JET
DEVELOPING...AND STRONG HEIGHT FALLS/SFC PRESSURE FALLS ACROSS GREAT
LAKES REGION. BASED ON RAPID DEEPENING SYSTEM AND STRONG LOW LEVEL
JET DEVELOPING...MAY NEED TO EVEN CONSIDER WIND HEADLINES BEGINNING
AS EARLY AS LATE MONDAY NIGHT. NEEDLESS TO SAY...VERY MILD
CONDITIONS FOR MONDAY NIGHT WITH LOWS LIKELY JUST ABOVE
CLIMATOLOGICAL HIGHS FOR LATE OCTOBER IN THE LOWER TO POSSIBLY EVEN
MID 60S.

LONG TERM...

MAIN ITEM OF INTEREST IN THE EXTENDED IS IMMINENT AT THE BEGINNING
OF THE PERIOD TUESDAY MORNING AS AN ALREADY INTENSE SFC LOW OVER
NORTHERN MN CONTINUES TO DEEPEN AS IT MOVES INTO SOUTHERN CANADA IN
RESPONSE TO ROBUST MID/UPPER LEVEL JET POURING INTO THE CONUS FROM
OFF THE PAC COAST.  LOW IS PROGGED TO DEEPEN TO NEAR 962MB PER 12Z
ECMWF AND VERY STRONG WIND FIELDS ACCOMPANY THE LLEVEL TROUGH AS IT
SWEEPS THROUGH BRISKLY BETWEEN 12-18Z TUES.  STILL SHYING AWAY FROM
SLOWER NAM TIMING WHICH REMAINS AN OUTLIER.  TIME HEIGHTS SUGGEST A
NARROW NEAR FRONTAL BAND OF PRECIP ALONG CONVERGENT AXIS WHICH WILL
EASILY MIX INTO STRONG NEAR SFC WIND FIELDS TO 50 KTS AT H925.
BIGGER QUESTION IS EFFICIENCY OF PRE FRONTAL MIXING GIVEN EARLY
MORNING TIMING BUT WILL REMAIN CONSERVATIVE GIVEN LACK OF INSTABILITY.

BEHIND FROPA CONTINUED WINDY CONDITIONS EXPECTED AS 35-40KT H925 WINDS
MIX DOWN IN CAA WITH STRONGER GUSTS BUT A REPRIEVE FROM PRECIP IN
DRY SUBSIDENT REGIME WHICH SHOULD HOLD THROUGH WED NIGHT AS WRAP
AROUND MOISTURE LARGELY REMAINS NORTH OF THE CWA. LAKE EFFECT
CONCERNS REMAIN ON THU WITH BORDERLINE DELTA TS AND THE 12Z ECMWF
HAS A WEAK SHRTWV MOVING THROUGH THE MEAN TROUGH OVER THE GREAT
LAKES.  GIVEN THESE ISSUES WILL LEAVE THU POPS IN PLACE ONCE MORE
DESPITE LITTLE CROSS MODEL SUPPORT FOR AN AREA WIDE CHC POP
REMAINING.

FAIR CONDITIONS THEREAFTER AS RIDGING RETURNS INTO SATURDAY.
BEGINNING TO GET A LITTLE BETTER AGREEMENT ON NEXT WEAK SHRTWV
MOVING THROUGH THE PLAINS INTO THE LOWER GREAT LAKES SAT NIGHT/SUN
BUT WITH LONG LEAD TIME AND TRACK JUST NORTH OF THE AREA WILL HOLD
OFF ON POP ADDITIONS.

MARINE...
A STORM WATCH WILL REPLACE THE GALE WATCH FOR THE NEARSHORE WATERS.
COMPUTER MODEL GUIDANCE STARTING TO COME INTO BETTER CONVERGENCE IN
THE HANDLING OF A POWERFUL STORM SYSTEM TO AFFECT THE AREA LATE
MONDAY NIGHT INTO TUESDAY. EXPLOSIVE DEEPENING OF SFC LOW PRESSURE
WILL OCCUR ACROSS THE UPPER MIDWEST MONDAY NIGHT INTO TUESDAY AND
THIS WILL ALLOW VERY STRONG SOUTHERLY WINDS TO DEVELOP LATE MONDAY
NIGHT. A POWERFUL COLD FRONT WILL TRACK ACROSS SOUTHERN LAKE
MICHIGAN TUESDAY MORNING WITH STORM FORCE SOUTHWEST GUSTS POSSIBLE
BEHIND THE FRONT. GIVEN SUCH STRONG PRESSURE FALLS TO THE NORTH...IT
IS POSSIBLE THAT HIGH GALES OR STORM FORCE SOUTHERLY GUSTS WILL BE
POSSIBLE AHEAD OF THE FRONT VERY LATE MONDAY NIGHT INTO TUESDAY
MORNING. WILL GO AHEAD AND UPGRADE THE GALE WATCH TO A STORM WATCH
FOR THE NEARSHORE WATERS.
