Area forecast discussion, Jul 22, 4:35 PM EDT, 1 hour 35 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
435 PM EDT FRI JUL 22 2011

.SYNOPSIS...
A HOT AND HUMID AIR MASS WILL REMAIN IN PLACE ACROSS THE REGION
THROUGH THE WEEKEND. A COLD FRONT WILL DROP TEMPERATURES CLOSER TO
NORMAL EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
A VERY UNSTABLE AIRMASS IS IN PLACE ACROSS OUR AREA THIS AFTERNOON
WITH MLCAPES IN THE 3500-4500 J/KG RANGE. THUNDERSTORMS ASSOCIATED
WITH SHORT WAVE ENERGY MOVING ACROSS THE SOUTHERN GREAT LAKES ARE
CURRENTLY MOVING INTO NORTHERN OHIO. THE SOUTHERN EDGE OF THESE
STORMS IS BEGINNING TO LAY OUT IN MORE OF AN EAST/WEST DIRECTION.
THIS COULD HELP CONFINE THE BULK OF PCPN TO ABOUT THE NORTHERN
THIRD OF OUR FA. ELSEWHERE ACROSS OUR AREA...EXPECT THUNDERSTORMS
TO BE MORE ISOLATED TO POSSIBLY SCATTERED AND BE A LITTLE LESS
ORGANIZED DUE TO LACK OF BETTER FORCING/DEEPER SHEAR. ONE PROBLEM
WITH THIS COULD BE INITIATION ALONG ANY BOUNDARY THAT COULD
POSSIBLY PUSH SOUTH FROM THE CONVECTION MOVING THROUGH THE NORTH.
DEEPER LAYER SHEAR IS WEAK BUT GIVEN THE DEGREE OF INSTABILITY...SOME
SEVERE STORMS REMAIN POSSIBLE. DAMAGING WINDS WILL BE THE MAIN
THREAT AS WARM TEMPERATURES AND HIGH WET BULB ZEROES SHOULD LIMIT
HAIL SIZE.
&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/...
THE UPPER LEVEL RIDGE WILL FLATTEN OUT SATURDAY INTO SATURDAY
NIGHT. AS IT DOES...WE WILL TRANSITION INTO A BIT MORE OF A
NORTHWEST FLOW PATTERN ALOFT. AS WE DESTABILIZE AGAIN ON
SATURDAY...EXPECT TO SEE SCATTERED THUNDERSTORM DEVELOPMENT ONCE
AGAIN...PRIMARILY FROM MID AFTERNOON INTO THE EVENING HOURS. WITH
RIDGE WEAKENING SOME...TEMPERATURES SHOULD NOT BE QUITE AS WARM AS
FRIDAY. THIS WILL KEEP HEAT INDICES NEAR THE ADVISORY/WARNING
CRITERIA WILL CONTINUE WITH CURRENT HEADLINES.
&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
ANOTHER HOT AND HUMID DAY WILL BE PRESENT ACROSS THE FA FOR SUNDAY.
A WEAK DISTURBANCE WILL MOVE INTO THE AREA ON SUNDAY ALLOWING FOR
SHOWERS AND THUNDERSTORMS ACROSS THE AREA.  THESE STORMS WILL KEEP
TEMPERATURES A COUPLE OF DEGREES COOLER THAN SATURDAY HOWEVER HIGH
TEMPERATURES WILL STILL BE ABOVE 90 DEGREES ACROSS THE AREA.  HEAT
INDEX VALUES WILL BE AROUND ADVISORY CRITERIA FOR SUNDAY AND
THEREFORE WILL CONTINUE TO MONITOR FOR POSSIBLE FUTURE HEADLINES.  A
COLD FRONT WILL MOVE THROUGH SUNDAY NIGHT INTO MONDAY ALLOWING FOR
ADDITIONAL SHOWERS AND THUNDERSTORMS.  COOLER TEMPERATURES IN THE
80S WILL BE PRESENT FOR MONDAY AND TUESDAY.  ANOTHER RIDGE BEGINS TO
BUILD INTO THE AREA FOR WEDNESDAY THROUGH THE END OF THE LONG TERM.
THIS RIDGE WILL ALLOW FOR TEMPERATURES TO INCREASE BACK INTO THE 90S.

&&

.AVIATION /20Z FRIDAY THROUGH WEDNESDAY/...
LINE OF THUNDERSTORMS PUSHING INTO NORTHWEST OHIO IS BEGINNING TO
LOSE ITS SOUTHWARD PUSH. THIS MAY LAY OUT ALONG THE INTERSTATE 70
CORRIDOR DURING THE NEXT HOUR OR TWO...PUTTING KDAY AND KCMH/KLCK
ON THE EDGE. AIRMASS WILL REMAIN VERY UNSTABLE ACROSS THE AREA
INTO THE EVENING HOURS SO ISOLATED TO SCATTERED THUNDERSTORM
ACTIVITY WILL OTHERWISE BE POSSIBLE. THUNDERSTORM ACTIVITY SHOULD
DIE OFF OVERNIGHT...WITH VSBY RESTRICTIONS DUE TO MIST/FOG
POSSIBLE AGAIN LATE TONIGHT INTO SATURDAY MORNING.

OUTLOOK...A CHANCE OF THUNDERSTORMS WILL CONTINUE THROUGH MONDAY.
