Area forecast discussion, Jul 21, 3:58 PM EDT, 1 hour 30 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
358 PM EDT WED JUL 21 2010

.SYNOPSIS...
ACTIVE SUMMERTIME PATTERN CONTINUES FOR THE GREAT LAKES WITH VERY
MOIST AIRMASS IN PLACE WITH MANY DISTURBANCES PASSING THROUGH THE
SEASONABLY FAST FLOW.

&&

.NEAR TERM /THROUGH TONIGHT/...
WILL CONTINUE TO HOLD ONTO FLASH FLOOD WATCH ACROSS NRN KY/FAR SRN
OHIO...DESPITE TREND IN MANY DETERMINISTIC MODEL RUNS TO SHOW
THINGS DRYING A BIT OVERNIGHT. ENOUGH DATASETS /NAMELY HI-RES
ARW/NMM FROM NCEP AND ALSO 3KM HRRR/ CONTINUE TO DEVELOP
CONVECTION OVER NRN KY THROUGH THIS EVENING TO WARRANT KEEPING
THE WATCH. OBSERVATIONAL DATASETS INCLUDING VISIBLE SATELLITE AND
SURFACE OBSERVATIONS CERTAINLY INDICATE BOUNDARY AND CONVERGENCE
REMAINS IN WEAK FASHION FROM CURRENT NRN KY SCATTERED CONVECTION
ALL THE WAY BACK INTO CNTL IL WHERE CONVECTION CONTINUES TO SLOWLY
ORGANIZE. THIS IS IN AN AXIS OF VERY IMPRESSIVE MOISTURE
POOLING...WITH PWAT IN EXCESS OF 2 INCHES. VERY HIGH FREEZING
LEVELS AND MOIST ADIABATIC MID LEVEL LAPSE RATES SUGGEST STORMS
WILL CONTINUE TO HAVE WARM RAIN PROCESSES. STORMS LATE THIS
AFTERNOON AND EVENING ALSO COULD HAVE SEVERE THREAT...WITH MLCAPE
IN EXCESS OF 2000 J/KG COUPLED WITH EFFECTIVE SHEARS IN EXCESS OF
35 KT UNDERNEATH RATHER FAST MID-UPPER LEVEL TROPOSPHERIC FLOW. IN
ADDITION...RATHER BUOYANT 0-3KM LAYER /CAPES IN EXCESS OF 150
J/KG/ AND WEAK LOW LEVEL SHEAR SUGGEST A FEW STORMS MAY HAVE THE
ABILITY TO MAINTAIN LOW LEVEL MESOS/BRIEF TORNADO THREAT...BUT
WOULD LIKE TO SEE OVERALL FLOW/HELICITY IN THE 0-1KM LAYER A
LITTLE STRONGER TO BE TOO CONCERNED ABOUT THIS. A FEW STORMS THIS
AFTERNOON THOUGH HAVE SHOWN SOME TENDENCY FOR BRIEF/WEAK ROTATION. WET
MICROBURSTS WILL CONTINUE TO BE A POSSIBILITY WITH WATER LOADED
CORES...AND IF STORMS CAN ORIENT INTO N-S SEGMENTS...THE WESTERLY
LOW LEVEL SHEAR VECTOR MAY ALLOW COLD POOL TO MAINTAIN AND BRIEF
BOWING SEGMENTS. SO PLENTY ON OUR PLATES THROUGH THIS EVENING. DO
EXPECT AT SOME POINT THIS EVENING THAT STORMS WILL BECOME MORE AND
MORE SCATTERED...BUT HAVE LEARY EYE ON FAR SWRN CWA /MAINLY SERN
IN/ WHERE CONVECTION MAY TEND TO BUBBLE MOST OF NIGHT AS IT BEGINS
TO FEEL LOW LEVEL JET DOWNSTREAM OF MID-CONUS STRONG DISTURBANCE.
CERTAINLY A TYPE OF SITUATION THAT COULD EVOLVE INTO MESOSCALE
BACKBUILDING OVER INDIANA AS THE EVENING/NIGHT WEAR ON.

ALSO A WEAK COLD FRONT TIED TO NERN CONUS SHORT WAVE WILL FOCUS
SCATTERED CONVECTION INTO THE EVENING HOURS. WILL NEED TO ACCOUNT
FOR THIS A BIT AS WELL. THIS IN A STRONGER FLOW/DEEPER SHEAR
REGIME SO THIS COULD BE SEVERE AT SOME POINT TOO.

&&

.SHORT TERM /THURSDAY THROUGH THURSDAY NIGHT/...
THE STRONG DISTURBANCE EJECTING INTO THE WESTERN GREAT LAKES ON
THURSDAY MORNING WILL CONTINUE TO DRIVE AN INCREASING LOW LEVEL
JET/MOISTURE TRANSPORT SIGNAL INTO IL/IN THROUGH THE DAY AND THIS
SHOULD SUPPORT AN ORGANIZING BAND OF SHOWERS/STORMS INTO PORTIONS
OF WESTERN FORECAST AREA. CONFIDENCE DETERIORATES ON HOW FAR THIS
CONVECTION MAKES IT INTO OUR AREA...SO FOR RIGHT NOW HAVE KEPT
MENTIONS MAINLY WESTERN 2/3RDS OF FORECAST AREA. WITH MAIN
DYNAMIC/THERMODYNAMIC SIGNAL REMAINING WELL TO NORTH/WEST...DON/T
EXPECT A SOLID LINE OF STORMS TO CROSS THE AREA...BUT AGAIN..WITH
SUCH IMPRESSIVE MOISTURE AROUND CAN/T RULE ANYTHING OUT.

THIS STRONG LOW LEVEL JET/MOISTURE TRANSPORT SIGNAL DRIVES ACROSS
MICHIGAN AND UP STATE NEW YORK THURSDAY AFTERNOON/NIGHT AND SHOULD
KEEP ACTIVITY TIED TO THE NORTH OF THE LOCAL AREA. COULD NOT
HOWEVER GO COMPLETELY DRY IN WARM SECTOR OF THIS SYSTEM AS
HEAT/HUMIDITY/CAPE WILL BE HIGH AND THERE MAY BE MCS OUTFLOW INTO
NRN/CNTL OHIO THAT KEEPS THREAT OF STORMS ACROSS THE AREA. OVERALL
THOUGH...DON/T EXPECT MUCH ACTIVE WEATHER IN THE AREA AS THIS
SHOULD BE FOCUSED NORTH/EAST.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
A BROAD UPPER RIDGE WILL REMAIN IN PLACE OVER THE EASTERN CONUS ON
FRIDAY...WITH A WEAK FRONTAL BOUNDARY AND ASSOCIATED MOISTURE DRAPED
ACROSS THE LOWER GREAT LAKES PARALLEL TO THE UPPER FLOW. THOUGH MOST
MOISTURE IS PROGGED TO STAY NORTH OF THE ILN AREA...WENT WITH A LOW
CHANCE FOR THUNDERSTORMS SINCE CONVECTION MAY STILL DEVELOP IN A
MODERATELY UNSTABLE AIRMASS COUPLED WITH RELATIVELY FAVORABLE WIND
FIELDS. WENT BELOW GUIDANCE FOR HIGH TEMPERATURES DUE TO SLIGHT
COOLING EFFECTS OF MOIST GROUND...THOUGH READINGS SHOULD STILL REACH
THE LOWER 90S.

FRONTAL ZONE WILL BEGIN TO SAG SOUTH FROM THE GREAT LAKES ON
SATURDAY...AND THEN TRAVEL ACROSS THE ILN AREA ON SUNDAY...REQUIRING
A CHANCE OF THUNDERSTORMS BOTH DAYS. HIGH PRESSURE MOVING DOWN FROM
THE NORTHWEST MAY BRING A PERIOD OF DRY WEATHER MONDAY THROUGH
WEDNESDAY.

VERY WARM TEMPERATURES WILL PERSIST ON SATURDAY AHEAD OF THE
FRONT...WITH HIGHS IN THE LOWER 90S EXPECTED. HIGHS CLOSE TO NORMAL
IN THE MID AND UPPER 80S ARE FORECAST FOR SUNDAY THROUGH TUESDAY.
SOUTHERN LOCATIONS MAY REACH 90 AGAIN NEXT WEDNESDAY WHEN A
SOUTHERLY FLOW DEVELOPS ON THE WEST SIDE OF THE HIGH.

&&

.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
CONVECTIVE BOUNDARY REMAINS ACROSS SOUTHERN FORECAST AREA THIS
AFTERNOON. EARLY STRATUS DECK HAS SCATTERED OUT OR LIFTED TO VFR
AT TAF SITES EARLY THIS AFTERNOON. CU FIELD SHOULD DEVELOP THIS
AFTERNOON WITH SCATTERED THUNDERSTORMS DEVELOPING THROUGH LATE
AFTERNOON. EXPECT BEST CHANCE OF SHOWERS/THUNDERSTORMS TO BE AT
KCVG/KLUK THIS AFTERNOON. HIGH MOISTURE CONTENT IN LOWER LEVELS OF
ATMOSPHERE CONTINUES AND HAVE INCLUDED IFR/MVFR VISIBILITIES IN
FOG AT KLUK...KCVG AND KILN FOR TOMORROW MORNING. CU FIELD WILL
DEVELOP AGAIN THURSDAY. PLACEMENT OF ANY CONVECTION ON THURSDAY DIFFICULT
TO DETERMINE AT THIS TIME.

OUTLOOK...BEST CHANCE OF THUNDERSTORMS SATURDAY THROUGH SUNDAY.
