AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
1042 PM EDT WED SEP 10 2014
.SYNOPSIS...
A STRENGTHENING LOW PRESSURE SYSTEM LIFTING UP ACROSS THE GREAT
LAKES TONIGHT WILL HELP PUSH AN ASSOCIATED COLD FRONT DOWN THROUGH
THE OHIO VALLEY TONIGHT INTO THURSDAY MORNING. WIDESPREAD SHOWERS
AND THUNDERSTORMS ARE EXPECTED ACROSS THE AREA TONIGHT WITH
LOCALLY HEAVY RAIN POSSIBLE. HIGH PRESSURE AND DRIER CONDITIONS
WILL BUILD INTO THE AREA THROUGH THE END OF THE WORK WEEK.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
...UPDATED TO EXPAND FFA FARTHER SOUTH...
A SOLID LINE OF THUNDERSTORMS HAS COME TOGETHER AHEAD OF AN
APPROACHING COLD FRONT...STRETCHING FROM SOUTHERN ILLINOIS ACROSS
CENTRAL INDIANA AND INTO NORTHERN OHIO. THIS LINE HAS BEEN SAGGING
SLOWLY SOUTHEAST AS INDIVIDUAL CELLS WITHIN THE LINE HAVE BEEN
PROGRESSING MORE EASTERLY. A SECONDARY AREA OF PCPN MOVING ACROSS
FAR SOUTHERN ILLINOIS AND INTO SOUTHWEST INDIANA IS ASSOCIATED
WITH A WEAK WAVE THAT WILL RIDE EAST ALONG THE FRONT
OVERNIGHT...LIKELY SLOWING UP THE SOUTHEAST PUSH OF THE FRONT.
THIS SHOULD ALLOW FOR THE PCPN TO CONTINUE TO CONGEAL AS IT WORKS
EAST INTO OUR AREA THROUGH THE OVERNIGHT HOURS. WITH PWS
INCREASING INTO THE 2 TO 2.5 INCH RANGE...PERIODS OF VERY HEAVY
RAIN WILL BE POSSIBLE. THE SEVERE THREAT APPEARS TO BE WANING AS
THE BETTER INSTABILITY IS GENERALLY WEST OF OUR AREA AND IT SHOULD
CONTINUE TO DECREASE AS WE PROGRESS THROUGH THE NIGHT.
HOWEVER...LOW LEVEL WIND PROFILES REMAIN IMPRESSIVE WHICH WOULD
STILL SUPPORT A LOW END SEVERE THREAT IF ANY STRONGER UPDRAFTS CAN
MAKE IT INTO OUR WESTERN AREAS OVER THE NEXT FEW HOURS.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/...
THE COLD FRONT WILL PUSH SOUTH OF THE AREA THURSDAY MORNING WITH
PCPN TAPERING OFF AS DRIER AIR WORKS IN FROM THE NORTHWEST. SURFACE
HIGH PRESSURE AND A COOLER AIRMASS WILL THEN BUILD INTO THE AREA
THURSDAY NIGHT INTO FRIDAY. EXPECT HIGHS ON FRIDAY ONLY RANGING
FROM THE MID TO UPPER 60S ACROSS THE NORTHWEST TO THE LOWER 70S IN
THE SOUTHEAST. A WEAK UPPER LEVEL DISTURBANCE WILL PUSH ACROSS THE
SOUTHERN GREAT LAKES FRIDAY NIGHT. THIS COULD RESULT IN A STRAY
SHOWER OR TWO ACROSS OUR FAR NORTH BUT THINK CHANCE IS LOW ENOUGH
TO LEAVE OUT OF FORECAST.
&&
.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
FOR THE FIRST PART OF THE EXTENDED...SOME VARIATION IN AVAILABLE
MOISTURE AND PLACEMENT OF PRECIPITATION ASSOCIATED WITH AN ELONGATED
AND FAIRLY QUICKLY MOVING S/WV IN THE LOWER GREAT LAKES DURING THE
DAY ON SATURDAY. ECMWF IS THE WEAKEST WITH THIS SYSTEM...WHILE GFS
IS MOST LIMITED IN MOISTURE. BECAUSE CONFIDENCE IS FAIRLY LOW AT
THIS TIME...HAVE LEFT RAIN OUT OF THE FORECAST FOR NOW FOR ANOTHER
MODEL RUN WITH CONSISTENCY. NOTICED THAT 12Z RUN OF ECMWF HAS BACKED
OFF ON THE MOISTURE SOME...SO THE TREND MAY BE MORE TOWARD THE MORE
CONSISTENT AND DRIER GFS.
THE OVERALL PATTERN IS THEN ONE OF OVERALL RIDGING AND NW
FLOW...BRINGING IN DRY AND COOLER THAN NORMAL TEMPS. THE RIDGE
SHIFTS TO THE EAST DURING THE DAY ON MONDAY AS ANOTHER WEAK
SHORTWAVE PUSHES THROUGH ESPECIALLY THE NORTHERN FCST AREA BRINGING
A CHANCE OF SHOWERS AGAIN FOR THE NORTH...FOLLOWED BY ANOTHER RIDGE
WITH NW FLOW.
DAYTIME HIGHS WILL REMAIN IN THE 60S TO LOW 70S...WITH OVERNIGHT
LOWS EARLIER IN THE EXTENDED IN THE MID 40S AND SLOWLY RISING TO
NEAR 50/LOW 50S.
&&
.AVIATION /03Z THURSDAY THROUGH MONDAY/...
LOW PRESSURE OVER NRN LWR MI TO STRENGTHEN AND TRACK THRU THE
GREAT LAKES TONIGHT. ASSOCIATED STRONG COLD FRONT TO SWEEP THRU
THE TAF SITES LATE TONIGHT. INITIAL WAVE OF SHOWERS AND THUNDERSTORMS
ASSOCIATED WITH STRONG LOW LEVEL JET HAS STAYED NORTH OF THE TAF SITES.
STORMS OVER INDIANA AND ILLINOIS AHD OF THE ADVANCING SFC COLD FRONT
EXPECTED TO ORGANIZE INTO A LINE WHICH WILL IMPACT THE TAF SITES
LATE THIS EVENING. STRONG TO SEVERE WINDS WILL BE POSSIBLE WITH
SOME OF THESE STORMS. HAVE MVFR CIGS AND IFR VSBYS WITH HEAVY
RAIN...BUT LOWER CIGS WILL BE POSSIBLE IN STRONGER STORMS.
ADDITIONAL SHOWERS...AND POSSIBLY EMBEDDED STORMS WILL OCCUR
ALONG THE COLD FRONT WHICH PUSHES THROUGH JUST BEFORE DAWN. HAVE
MVFR VSBYS AND CIGS WITH PREVAILING SHOWERS FOR THIS PERIOD...ALTHOUGH
CAN NOT RULE OUT THUNDER.
A SHARP WIND SHIFT TO THE NORTHWEST WILL OCCUR EARLY THURSDAY
AFTER THE FRONT PASSES. MVFR...POSSIBLY LOWER...CEILINGS WILL ALSO
BE FOUND IN THE WAKE OF THE FRONT THURSDAY MORNING. EXPECT IMPROVING
CONDITIONS TO VFR THURSDAY AFTN.
OUTLOOK...NO SIGNIFICANT WEATHER.
