AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE CLEVELAND OH
651 PM EDT THU JUL 22 2004
.UPDATE...
BAND OF TSTM HV DVLP ACRS LWR ONTARIO INTO NERN IN. NOT A CONTINUOUS
LN SO STABILITY EFFECTS OF LERI MAY KILL CONVECTION AS IT MOVS SE
ACRS THE LAKE...BUT NOT ENTIRELY CERTAIN THIS WL HAPPEN. HV
INTRODUCED A CHC FOR NERN PART OF FCST AREA AND HV REMOVED AFT MID
WORDING.
&&
.SHORT TERM (TONIGHT-SUNDAY)...
SFC FRONT EXTENDING FROM CENTRAL LK HURON THROUGH SRN WI WL MOVE
THRU THE AREA OVERNIGHT...LEADING THE WAY FOR A SIGNIFICANT
COOLDOWN. EVEN THOUGH IT WILL BE LATE JULY...IT WILL FEEL LIKE EARLY
AUTUMN OVER THE WEEKEND.
FIRST THINGS FIRST THOUGH. A FORWARD PROPAGATING MCS HAS DEVELOPED
OVER IOWA AND ILLINOIS AND IT SHOULD INTENSIFY AS IT MOVES INTO THE
EXTREME INSTABILITY OVER INDIANA. AS IT MOVES TOWARD OHIO...IT WL
LIKELY TURN RIGHT AS IT FOLLOWS THE CORFIDI VECTORS THIS EVENING.
HOWEVER...THE ETA AND GFS WOULD SUGGEST THAT THE SYSTEM WL NOT BE
ABLE TO TURN RIGHT IN TIME TO MISS THE WESTERN 1/2 OF THE FORECAST
AREA. HAVE KEPT POPS IN THE 30-40 IN THE I-71 CORRIDOR...AND 40-50
FROM TOL-FDY. HAVE OPTED TO KEEP EXTREME NE OH/NW PA DRY WITH LACK
OF INSTABILITY THIS AFTN...AND LIKELIHOOD THAT MCS WL MISS THEM.
OTHER THAN THE MCS...DO NOT REALLY EXPECT ANY STORMS TO DEVELOP IN
ADVANCE OF THE FRONT AS CLD CVR FROM MRNG COMPLEX HAS NOT ALLOWED
FOR MUCH DESTABILIZATION OVER EASTERN OHIO/NW PA THIS AFTN. WESTERN
OHIO IS SEEING SOME SUNSHINE THIS AFTN...AND THAT AREA WOULD HAVE
THE BEST CHANCE FOR STORMS THIS EVENING. IF MCS DOES NOT MAKE THE
TURN IN TIME...THERE IS A SEVERE THREAT FOR WESTERN OHIO...BUT THINK
THAT SEVERE THREAT IS MINIMAL FOR EASTERN OHIO/NW PA. OTHER THAN
THAT...THE PCPN WL BE CONFINED MAINLY TO THE MCS...OR REMNANTS THERE
OF.
BY 12Z...THE FRONT SHOULD BE JUST SE OF THE FORECAST AREA.
HOWEVER...THE FRONT WL BE CLOSE ENOUGH TO WARRANT 30 POPS IN THE
MORNING BEFORE THE CANADIAN HIGH BUILDS IN. A SIGNIFICANT CHANGE OF
WEATHER IS IN STORE FOR THE GREAT LAKES WITH MUCH DRIER AND COOLER
WEATHER FOR THE WEEKEND. 850MB TEMPS DROP TO A VERY AUTUMN LIKE +6C
ACROSS THE FORECAST AREA...WITH NE SFC WINDS DEVELOPING FRI AFTN.
WITH THE LAKE AROUND 22C...DELTA-T VALUES ARE SUFFICIENT FOR LAKE
CLOUDS. WL BE INTERESTING IF ANY LAKE EFFECT RAIN SHOWERS CAN SET UP
WITH THE STEEP LOW LVL LAPSE RATES FRI NIGHT/SAT...ALTHOUGH AMT OF
DRY AIR WILL BE MAIN INHIBITING FACTOR.
WKND SHOULD BE VERY PLEASANT. MIGHT HAVE A CHANCE TO SEE RECORD LOWS
AT SOME POINT DURING THE WKND...ESPECIALLY OVER INLAND NW AND
N-CENTRAL OHIO. THINK BEST CHANCE WOULD BE SUN MORNING WHEN RIDGE
AXIS IS A LITTLE CLOSER TO WESTERN OHIO. ETA 2M TEMPS DROP INTO THE
LOW-MID 40S OVER INLAND AREAS. DO NOT THINK TEMPS WL DROP THAT
LOW...BUT IT IS POSSIBLE THAT TEMPS AROUND 50 WL OCCUR AWAY FROM THE
LAKE. ALTHOUGH THIS PACKAGE WL NOT MENTION RECORD LOWS FOR THE
WEEKEND...IT IS A POSSIBILITY. FOR REFERENCE HERE ARE SOME SELECTED
RECORD LOWS FOR THE WKND...
7/25 7/26
TOL 50 50
FDY 51 47
CLE 47 46
MFD 52 53
CAK 47 44
YNG 44 49
ERI 49 52
EVEN IF NO RECORDS ARE BROKEN...HIGHS OVER THE WKND WL BE
UNSEASONABLY COOL...GENERALLY IN THE LOWER 70S.
&&
.LONG RANGE (SUNDAY THROUGH THURSDAY)...
A RELATIVELY COOL PATTERN WL CONTINUE THRU THE PERIOD WITH A TROUGH
REMAINING OVER THE EASTERN HALF OF THE COUNTRY...WITH THE UPSTREAM
ATLC RIDGE IN PLACE. POLAR FRONT REMAINS THE FOCUS FOR PCPN THRU THE
PERIOD...WITH MDLS SHOWING THAT FEATURE REMAINING S OF THE AREA THRU
THU. HOWEVER...THE MDLS SHOW SOME TYPE OF AN INVERTED TROUGH OVER
THE APPALACHIANS/OH VLY TUE-THU AS THE AREA REMAINS IN DIFFLUENT
FLOW ALOFT. WL THEREFORE HAVE TO CONTINUE WITH CHC POPS FOR THE
TUE-THU TIME FRAME. COOL AND DRY CANADIAN HIGH PRES SHOULD REMAIN
STRONG ENOUGH OVER THE FORECAST AREA ON MONDAY TO KEEP ANY PCPN S OF
THE AREA DESPITE THE 12Z GFS SHOWING PCPN MOVING NWD MON MORNING.
TEMPS IN THE EXTENDED WL REMAIN BELOW NORMAL...ALTHOUGH THEY MAY
WARM TO NEAR NORMAL BY THU WITH 850 MB TEMPS RISING TO AROUND 15C.
