SWEEP THROUGH THE OHIO VALLEY TODAY. GUSTY WINDS WILL USHER IN
MUCH COLDER AIR IN THE WAKE OF THIS FRONT LATER THIS AFTERNOON AND
TONIGHT. HIGH PRESSURE WILL BUILD OVER THE AREA ON WEDNESDAY...
PROVIDING SEASONABLY COOL AND DRY WEATHER.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
SFC OBS SHOW APPROACHING COLD FRONT NEAR KORD TO KSTL...AND THIS
FEATURE WILL MOVE INTO THE CWA LATER THIS AFTERNOON. LL MOISTURE
AHEAD OF THIS FEATURE NOT AS WIDESPREAD AS EARLIER ANTICIPATED AND
PRECIP HAS YET TO DEVELOP ASIDE FROM SCT ELEVATED CONVECTION OVER
CNTRL KY. UPDATED FORECAST TO LOWER CLOUD COVER TO PC AREAWIDE AND
DELAYED ONSET OF PRECIP UNTIL AFTER 18Z...SINCE BEST CONVERGENCE
DOESNT APPEAR TO SET UP UNTIL 20-21Z ACROSS THE I-71 CORRIDOR.
KEPT HIGH CHANCE POPS LATE THIS AFTERNOON FROM HERE EASTWARD AND
LOWERED THEM SLIGHTLY ACROSS THE WEST. MAINTAINED MENTION OF
THUNDER ACROSS THE SRN HALF...WITH DEVELOPING ELEVATED INSTBY
EVIDENCED BY CONVECTION OVER KY. WITH MORE SUNSHINE...BUMPED HIGHS
UP A CAT AREAWIDE WITH SOME LOCATIONS UPSTREAM ARE ALREADY IN THE
LOWER 60S. ILN AND AOH ALREADY GUSTING TO 30+ KT WITH GUSTS NEAR 25
KT ELSEWHERE. WITH INCREASED SUN...WE WILL PROBABLY MIX A BIT
HIGHER THAN ANTICIPATED SO INCREASED GUSTS INTO THE 35-40 MPH
RANGE.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/...
DRY SLOT TO WORK ACRS THE AREA AND DRY OUT THE ENTIRE FA THIS
EVENING. HAVE MAINTAINED DRY FCST THRU THE OVERNIGHT HOURS
WITH WRAP AROUND PRECIP EXPECTED TO HOLD OFF UNTIL AFTER 12Z
TUE. HAVE FAVORED A BLEND OF MAV/MET TEMPS FOR LOWS TONIGHT.

IN STRONG COLD AIR ADVECTION PATTERN -8 8H TEMPS TO NOSE INTO FA
ON TUE. ALSO EXPECT A CONSIDERABLE AMOUNT OF STRATO CUMULUS CLDS
WITH FAVORABLE FETCH OFF LM PROVIDING MIXED SNOW/RAIN SHOWERS ACRS
THE NORTH. MAV GUID TEMPS AND GRIDDED MOS APPEAR WAY TOO WARM
IN THIS AIRMASS AND HAVE ADJUSTED CLOSER TO THE COLDER MET GUID
FOR HIGHS. WINDS WILL AGAIN BE GUSTY WITH GUSTS TO AROUND 35 MPH
TUES AND TUES EVE. CLDS TO HANG ON THRU MOST OF THE NIGHT TUE
WITH IMPROVING COND WED AS HIGH PRESSURE BUILDS IN. AGAIN PREFER
A BLEND WITH LOW TEMPS TUE NIGHT AND COLDER THAN MAV GUID ON WED.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
HIGH PRESSURE WILL BE MOVING ACROSS THE REGION AT THE BEGINNING OF
THE PERIOD. THEN A LOW IS FORECAST TO CROSS THE LOWER GREAT LAKES
THURSDAY INTO FRIDAY. OPERATIONAL GFS HAS BEEN SHOWING A FAIR AMOUNT
OF VARIABILITY OVER THE PAST SEVERAL RUNS IN REGARDS TO THIS SYSTEM.
BUT THE 12Z GFS HAS COME CLOSER IN LINE WITH 00Z AND 06Z GFS
ENSEMBLES. THIS WOULD SUGGEST THAT THE BEST CHANCE OF RAIN WITH THE
LOW AND ASSOCIATED FRONT WOULD BE THURSDAY NIGHT POSSIBLY
LINGERING INTO FRIDAY MORNING IN EASTERN ZONES. AT THIS POINT EXPECT
LOW LEVEL TEMPERATURES TO BE WARM ENOUGH FOR ANY PRECIPITATION TO BE
IN THE FORM OF RAIN.

ANOTHER HIGH WILL BUILD ACROSS THE REGION ON SATURDAY. A VIGOROUS
SYSTEM IS FORECAST TO DEVELOP IN THE PLAINS DURING THE WEEKEND. BUT
THERE IS MUCH UNCERTAINTY CONCERNING THE SPEED. FOLLOWING THE SLOWER
00Z ECMWF SEEMED TO BE THE PRUDENT CHOICE AT THE TIME. SO SHOWERS
MAY ONLY AFFECT THE WESTERN ZONES ON SUNDAY.

TEMPERATURES ARE FORECAST TO BE SLIGHTLY BELOW NORMAL THROUGH THE
PERIOD.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
COLD FRONT CURRENTLY MOVING INTO WRN INDIANA WILL MOVE INTO SW AND
CNTRL OH LATER THIS AFTERNOON. CU FIELD IS BEGINNING TO DEVELOP
AHEAD OF THE FRONT...AND EXPECT SHRA TO DEVELOP OVER THE NEXT 2
HRS OR SO AS THE FRONT APPROACHES WRN OH. BEST CHANCE FOR PRECIP
WILL BE AT KCMH AND KILN AND POINTS EAST AS CONVERGENCE ALONG
FRONT BEGINS TO MAXIMIZE ACROSS THIS AREA. WENT TEMPO SHRA WITH
MVFR CONDITIONS AT THESE LOCATIONS WITH VCSH AT THE KCVG/KDAY
TERMINALS WHERE SHRA WILL BE MORE SCATTERED. ADDED CB TO KCVG/KILN
TO ACCOUNT FOR ELEVATED INSTBY OVER SRN OH. HOWEVER...EXPECT ANY
THUNDER TO BE MORE ISOLATED SO DID NOT PUT IT IN ANY TAF FOR NOW.
CLOUDS SHOULD BE QUICK TO SCATTER OUT AFTER FRONTAL PASSAGE BUT
SCT LOW CLOUDS MAY LINGER OVERNIGHT ACROSS CNTRL OH.

OTHER CONCERN IS WINDS WHICH ARE CURRENTLY GUSTING 25-33KT. GUSTS
WILL CONTINUE AHEAD OF THE FRONT THOUGH THEY MAY SUBSIDE SLIGHTLY
BEFORE FROPA. STRONG CAA BEHIND THE FRONT WILL FAVOR GUSTS PICKING
BACK UP FROM THE WEST/WNW AFTER SUNSET...BEFORE THE GUSTINESS
SUBSIDES AFTER MIDNIGHT. GUSTS WILL AGAIN RETURN TUESDAY DURING
THE DAYTIME HEATING.

OUTLOOK...GUSTS TO 30KT WILL CONTINUE TUESDAY AFTERNOON AND EVENING.
