AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
709 PM EDT FRI JUL 27 2007

.SYNOPSIS...
A COLD FRONT WILL APPROACH THE REGION LATE TONIGHT AND CROSS THE
REGION SATURDAY AFTERNOON. HIGH PRESSURE WILL GRADUALLY BUILD INTO
THE AREA SATURDAY NIGHT AND SUNDAY.

&&

.NEAR TERM /UNTIL 8 PM THIS EVENING/...
INSTABILITY HAS BEEN BUILDING ALL AFTERNOON ESPECIALLY OVER
WESTERN OHIO WHERE CAPE VALUES HAVE RISEN TO OVER 2500 J/KG AS
DEEP SHEAR (0-6KM) HAS RISEN TO 25-30 KNOTS OVER THE SAME AREA.
SOME INSTABILITY IS EVIDENT EAST ALONG THE LAKESHORE FROM CLE TO
ERI WHILE RAIN COOLED STABLE CONDITIONS EXIST FROM MEDINA COUNTY
TO YNG. CONVECTIVE CIN IS NEARLY ZERO ACROSS ALL BUT THE EASTERN
COUNTIES AND CONVECTION HAS DEVELOPED JUST WEST OF TOL FDY AREA
WHERE THE INSTABILITY IS GREATEST. THIS ACTIVITY SHOULD PROGRESS
ESE INTO THE REGION THIS EVENING AND MAY BECOME SEVERE. RECENT
HEAVY RAIN MAY INCREASE THE FLOOD RISK AS WELL BUT WILL NOT ISSUE
A FFA AT THIS TIME.

&&

.SHORT TERM /8 PM THIS EVENING THROUGH SATURDAY NIGHT/...
CONVECTION WILL LIKELY DIMINISH AFTER SUNSET THIS EVENING BUT THE
CHANCE OF STORMS WILL LIKELY INCREASE AROUND NOON ON SATURDAY AS
THE COLD FRONT DROPS SOUTH OF LAKE ERIE INTO NORTHERN OHIO AND NW
PA. INSTABILITY IS EXPECTED TO BE MODERATELY HIGH OVER 2000 J/KG
ESPECIALLY EAST OF I-77 AND SOUTH OF I-90.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
FAIR WEATHER WITH A GRADUAL WARMING TREND IS IN STORE FOR THE
REGION AS HEIGHTS RISE OVER THE EASTERN STATES AND WARMER AIR OVER
THE MIDWEST GRADUALLY SPREADS EAST. BOTH GFS AND ECMWRF ARE
FORECASTING HEIGHTS TO RISE OVER THE EASTERN STATES UNTIL LATE IN
THE WEEK WHEN A WEAK SHORT WAVE WILL BRUSH ACROSS THE NORTHERN
TIER STATES WHICH MAY DRAG A WEAK COLD FRONT INTO THE AREA FRIDAY.
THIS FEATURE MAY PRODUCE SCATTERED SHOWERS AND THUNDERSTORMS. HAVE
USED GFS GRIDDED MOS WITH MINOR CHANGES.

&&

.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
AFTERNOON INSTABILITY HAS RESULTED IN SCATTERED TSTMS ACROSS THE
AREA. EXPECT CONVECTION TO BECOME INCREASINGLY SPARSE THROUGH THE
EVENING. WEAKENING COLD FRONT/TROF JUST TO OUR NORTHWEST WILL MOVE
THROUGH THE AREA OVERNIGHT AND BRING IN SLIGHTLY DRIER MORE STABLE
AIR ON A NLY FLOW. FOR THE EVENING WILL CARRY TEMOP THUNDER FOR A
FEW HOURS IN KCAK AND SHWRS IN KCLE...OTHERWISE VCTS OR NOTHING.
DRY AIR ALOFT WILL SPREAD IN AND WITH THE LOW LEVEL MOISTURE
REMAINING IN PLACE WOULD EXPECT FOG TO DEVELOP MOST PLACES.
BROUGHT IN MVFR VSBYS TRENDING TO IFR BY EARLY MORNING. SATURDAY
AFTERNOON THE NAM12 CONTINUES TO SHOW AFTERNOON INSTABILITY WITH
CAPES APROACHING 2000J/KG. WITH LACK OF FORCING BEHIND THE BOUNDRY
WILL LEAVE OUT ANY FORECAST OF CONVECTION FOR NOW.

BEHIND COLD FRONT...EXPECT CONDITIONS TO IMPROVE BY SUNDAY AS HIGH
PRESSURE BUILDS INTO THE AREA. THIS AREA OF HIGH PRESSURE WILL BE
THE DOMINATE WEATHER FEATURE INTO THE FIRST HALF OF NEXT
WEEK...AND WILL ALLOW FOR MAINLY VFR CONDITIONS IN THE AREA DURING
THE DAY.

&&

.MARINE...
LOW PRESSURE CURRENTLY LOCATED OVER LOWER LAKE MICHIGAN WITH A WARM
FRONT EXTENDING BACK TOWARD THE MISSISSIPPI RIVER. THE LOW AND THE
ASSOCIATED COLD FRONT WILL MOVE ACROSS LAKE ERIE TONIGHT WITH THE
FRONT JUST SOUTH OF THE LAKE SATURDAY MORNING. AHEAD OF THE
FRONT...THINK THAT THE WINDS WILL PICK UP OUT OF THE SOUTHWEST BUT
REMAIN AROUND 10-15KTS.  POST-FRONTAL PRESSURE GRADIENT AND COLD
ADVECTION RELATIVELY BENIGN SO AM NOT EXPECTING A BIG INCREASE IN
THE WINDS/WAVES SATURDAY.  HIGH PRESSURE SETTLES OVER THE LAKE ON
SUNDAY AND WILL REMAIN IN PLACE THROUGH THE MIDDLE OF NEXT WEEK.

&&

.CLE WATCHES/WARNINGS/ADVISORIES...
OH...NONE.
