&&

.PREV DISCUSSION...
SHORT TERM...
TONIGHT AND SUNDAY...
THE POTENTIAL FOR A CONVECTIVE WIND EVENT STILL SHAPING UP FOR
OVERNIGHT TONIGHT. THE FIRST AND INITIAL WEAKER SHORT WAVE EMBEDDED
IN SW FLOW WAS HELPING TO TRIGGER SHOWERS AND A FEW STORMS OVER IL
AND EXTENDING INTO NORTHERN INDIANA AFTERNOON AS MILD AND MOIST AIR
WAS SPREADING NORTH. SURFACE REPORTS INDICATED ONLY LOCALIZED SMALL
HAIL WITH THE STORMS OVER IL. IMMEDIATELY BEHIND THE FIRST SHORT
WAVE IS A SECOND AND STRONGER SYSTEM. OVERALL...HAVE TRENDED ONGOING
GRIDS/FORECAST SLOWER WITH THE TIMING OF THIS STRONGER SHORTWAVE
EJECTING OUT OF THE PLAINS INTO THE MIDWEST. EXPECT RAPID
CYCLOGENESIS OF THE SURFACE LOW ENTERING WEST CENTRAL MO AT 20Z.
THIS LOW WILL RACE NORTHEAST ABOUT SPI/BEH TRACK WITH A TRAILING
COLD FRONT MOVING EAST OVERNIGHT. EXPECT A LINE OF STORMS TO DEVELOP
ALONG/AHEAD OF THIS FRONT. NAM FORECAST CAPE UP TO 1000 J/KG...BUT
POTENTIAL FOR DAMAGING WINDS EXISTS AS WINDS BETWEEN 900 MB AND 600
MB REACH 70 TO 90 KNOTS. MAY NEED ONLY RELATIVELY WEAK CONVECTION TO
CHANNEL SOME OF THE HIGH WINDS DOWN TO THE SURFACE. GUT FEELING IS
SQUALL LINE WILL FORM OVER IL AND MOVE INTO NORTHERN INDIANA/FAR SW
LOWER MI AFTER MIDNIGHT AND RACE EAST. THEREFORE...HAVE KEPT THE
MENTION OF DAMAGING WINDS OVERNIGHT FOR ALL FORECAST AREAS. FOR
SUNDAY...KEPT WINDS JUST BELOW ADVISORY CRITERIA AS SFC LOW RACES
RAPIDLY TO THE NORTHEAST. MAY BE AN HOUR OR 2 OF SUSTAINED WINDS
AROUND 30 KNOTS...BUT FELT THE DURATION WAS TOO SHORT TO HOIST AN
ADVISORY. ONLY CAVEAT IS IF THE DRY SLOT PUSHES INTO THE AREA AND
SKIES CLEAR FOR A FEW HOURS. ANY EARLY MORNING SUN MAY BE SUFFICIENT
TO MIX 55-60 KNOT LOW LEVEL WINDS DOWN TO THE SURFACE.
OTHERWISE...WINDS SHOULD DIMINISH THROUGH THE AFTERNOON AS LOW MOVES
QUICKLY AWAY FROM THE AREA AND GRADIENT SLACKENS.

LONG TERM...
SUNDAY NIGHT THROUGH SATURDAY...
FCST PERIOD WILL BEGIN WITH SFC HIGH PRESSURE RIDGE CENTERED OVER
OH/TN VALLEY. THIS SLIDES OFF TO THE EASTERN SEABOARD BY MONDAY NITE
BRINGING MILD SW FLOW BACK INTO THE AREA FOR TUESDAY AS HIGHS WILL
ONCE AGAIN BE MORE THAN 10F ABOVE NORMAL. RETURN FLOW WILL ALSO
BRING WARM FRONT THROUGH THE AREA AS LOW PRESSURE DEVELOPS IN THE
PLAINS. BOTH NAM AND GFS FORECASTING 50KT LLJ TO FORM IN MID-MS
VALLEY MONDAY NIGHT AND MAY PROVIDE SUFFICIENT FORCING AS MOISTURE
POOLS ALONG THE FRONT TO GENERATE A FEW SHOWERS AHEAD OF THE FRONT
LATE MON NITE/TUE AM. FOR NOW WILL STAY WITH GOING DRY FCST AND SEE
HOW SUBSEQUENT RUNS HANDLE THIS. AS THIS AREA OF LOW PRESSURE LIFTS
NORTHEAST OUT OF THE PLAINS ANOTHER STRONG COLD FRONT WILL PUSH
THROUGH THE AREA MID-WEEK. MEDIUM RANGE MODELS AGAIN ADVERTISING
VERY STRONG WIND PROFILE WITH THIS SYSTEM...80KT MID-LEVEL JET AND
120KT UPPER LEVEL JET...SO POTENTIAL EXISTS FOR ANOTHER ROUND OF
STRONG THUNDERSTORMS. 12Z RUN OF GFS BEGINNING TO LAG SOUTHERN END
OF FRONT WHICH WOULD SLOW THE TIMING OF PRECIP AND FROPA IN OUR
AREA. NO PLANS TO MAKE ANY TIMING ADJUSTMENTS RIGHT NOW...WILL HOLD
OFF FOR BETTER RUN TO RUN CONSISTENCY. ANOTHER WEAK SFC RIDGE MOVES
INTO THE OH/TN VALLEY FOR DAY 6 AND 7 GIVING DRY WX AND NEAR NORMAL
TEMPS.
