AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
345 PM EDT SAT JUL 11 2009

.SYNOPSIS...
A COLD FRONT OVER NORTHWEST OHIO CROSS THE AREA THIS EVENING.
HIGH PRESSURE FROM THE NORTHERN PLAINS WILL MOVE EAST ACROSS THE
GREAT LAKES EARLY IN THE WEEK.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
COLD FRONT ACROSS NW OHIO. SOME MODERATE CUMULUS DEVELOPMENT IN THE
LAST HOUR OR TWO. DEWPOINTS ARE HIGH BUT THE AIRMASS IS OBVIOUSLY
RAIN COOLED AND SOMEWHAT MORE STABLE THAN IT COULD HAVE BEEN IF
THERE WERE NO RAIN IN THE MORNING. DESPITE THE EARLIER RAIN THE
LIFTED INDEX SEEMS BE AVERAGING -4 TO -6 WITH CAPE 800-1600 WHICH
ARE RESPECTABLE LEVELS. THINK WE WILL SEE NEW THUNDERSTORMS DEVELOP
MAINLY SOUTH OF THE LAKESHORE AND MAINLY FROM THE I-71 CORRIDOR
EASTWARD. THERE MAY BE ENOUGH TIME FOR THE STORMS TO GET SOME PUNCH
BEFORE EXITING THE FORECAST AREA AND THE AREA FROM YOUNGSTOWN TO
CANTON... MILLERSBURG AND MOUNT VERNON MAY BE MOST SUSCEPTIBLE. WILL
USE LEFTOVER WEATHER (LATE AFTERNOON) FOR THE NORTHERN COUNTIES AND
EVENING SHOWERS STORMS FOR THE ABOVE MENTIONED AREA. GUIDANCE TEMPS
LOOK A LITTLE COOL CONSIDERING HOW SHORT THE NIGHTS ARE THIS TIME OF
YEAR AND HOW FAR WE WOULD HAVE TO FALL TO GET THERE.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY NIGHT/...
ALL MODELS INDICATE AN AREA OF SHOWERS/STORMS WILL DEVELOP OVER THE
NORTHERN PLAINS LATE SAT NIGHT AND MOVE SOUTHEAST ON SUNDAY.
ACTIVITY SHOULD DIMINISH DURING THE DAY SUNDAY IN DRIER AND MORE
STABLE AIR ALTHOUGH SOME OF THE MODELS IN A TYPICAL CONVECTIVE
FEEDBACK MODE POST QPF ALL THE WAY TO NORTHERN OHIO. COULD BE SOME
DEBRIS CLOUDS BY SUNDAY AFTERNOON. LESS HUMID MOVES IN BY SUNDAY AS
YET ANOTHER IN A SERIES OF DRY HIGH PRESSURE SYSTEMS SLIDE SOUTHEAST
ACROSS THE GREAT LAKES WHILE THE UPPER TOUGH DEEPENS AGAIN OVER
QUEBEC. WE SHOULD REMAIN BETWEEN SYSTEMS WITH THE INSTABILITY
SHOWERS ASSOCIATED WITH THE UPPER TROUGH TO OUR NORTHEAST AND WARM
ADVECTION CONVECTION TO OUR WEST. WARM FRONT WILL APPROACH BY
WEDNESDAY MORNING.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
THE LONG TERM PERIOD WILL START OUT WITH WEATHER LEFT OVER FROM THE
AREA OF LOW PRESSURE SET TO MOVE ACROSS THE REGION DURING THE MIDDLE
PART OF THE WEEK.  IT APPEARS THAT DRIER AIR WILL BE A LITTLE SLOWER
TO ARRIVE BEHIND THIS SYSTEM THAN EARLIER THOUGHT.  WILL NEED TO
KEEP CHANCE POPS GOING THROUGH WEDNESDAY NIGHT AND INTO EASTERN
AREAS THROUGH AT LEAST MIDDAY THURSDAY.  HIGH PRESSURE WILL BUILD
OVER THE LOCAL FOR THE END OF THE WEEK.  AS HAS BEEN THE CASE A LOT
LATELY... TEMPERATURES DURING THE PERIOD WILL AGAIN AVERAGE A LITTLE
BELOW NORMAL.  MANY AREAS WILL STRUGGLE TO GET OUT OF THE 70S BOTH
FRIDAY AND SATURDAY.

&&

.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
THE PREFRONTAL LINE OF SHRA/TSRA IS JUST NOW EXITING THE AREA. THE
COLD FRONT IS NOW OVER NW OH AND SHOULD MOVE E ACROSS THE
REMAINDER OF THE AREA THIS AFTERNOON. HAVE SEEN SOME CLEARING
BEHIND THE FIRST LINE OF STORMS. THIS CLEARING MAY BE ENOUGH TO
ALLOW ANOTHER ROUND OF SHRA/TSRA TO DEVELOP AS THE FRONT NEARS.
HOPEFULLY EARLIER RAINS HAVE WORKED THE ATMOSPHERE OVER ENOUGH THAT
THINGS DONT GET OUT OF HAND. AS IT APPEARS RIGHT NOW...THINK THE
BEST CHANCES FOR MORE STORMS WILL BE OVER THE SE CORNER OF AREA
WHERE GOOD HEATING IS NOW OCCURRING. WILL GIVE MOST PLACES A VCNTY
MENTION OF THUNDER FOR THE TIME BEING. AFTER 00Z THINGS SHOULD
BEGIN TO DRY OUT. THERE WILL LIKELY BE AT LEAST PATCHY MVFR FOG
LATER TONIGHT.

OUTLOOK...VFR SUNDAY THROUGH TUESDAY. PERIODS OF NON-VFR WED WITH
SHRA/TS.

&&

.MARINE...
THE COLD FRONT IS JUST NOW APPROACHING THE WEST END OF THE LAKE.
THIS FEATURE WILL MOVE EAST ACROSS THE LAKE THIS EVENING.  SW FLOW
AHEAD OF THE FRONT WILL BECOME W THEN NW TO N TONIGHT.  WINDS WILL
BRIEFLY BE IN THE 15 TO 20 KNOT RANGE BEHIND THE FRONT SO WILL KEEP
SMALL CRAFT GOING AS IS.  WINDS AND WAVES WILL QUICKLY COME DOWN
LATE TONIGHT AND SUNDAY SHOULD BE A DECENT DAY ON THE LAKE WITH
MAINLY WEST WINDS LESS THAN 10 KNOTS.  WINDS WILL CHANGE LITTLE TILL
ANOTHER FRONTAL PASSAGE MONDAY NIGHT INTO TUESDAY.  MAINLY WESTERLY
FLOW WILL THEN CONTINUE THROUGH LATE TUESDAY.  AT THAT TIME A WARM
FRONT WILL LIFT NORTH ACROSS THE REGION FINALLY GIVING THE FLOW A
SOUTHERLY COMPONENT.  THE BEST CHANCES FOR RAIN DURING THE PERIOD
WILL COME DURING THE TUESDAY NIGHT INTO WEDNESDAY PERIOD.  A COLD
FRONT WILL EVENTUALLY MAKE ITS WAY ACROSS THE LAKE LATE WEDNESDAY
INTO THURSDAY CAUSING THE FLOW TO AGAIN BECOME WESTERLY.
