AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
312 PM EDT TUE MAY 15 2007

.SYNOPSIS...
A STRONG COLD FRONT WILL MOVE FROM WEST TO EAST ACROSS THE AREA
TONIGHT. A LINGERING TROUGH WILL EXTEND BACK THROUGH THE GREAT
LAKES FOR A COUPLE OF DAYS WHILE HIGH PRESSURE WILL WORK IN FROM
THE WEST LATE WEEK.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
EARLIER SOUNDING (ILN) WAS ESSENTIALLY CAPPED BUT 18Z SOUNDING
GETTING MUCH MORE UNSTABLE AND ADDING CAPE. SVR WX WATCHES JUST TO
THE WEST AT THIS TIME. RUC INDICATES BEST INSTABILITY WILL SHIFT
NE ACROSS SE LWR MI LATE AFTERNOON AND PERHAPS (MAYBE?) THE
STRONGEST CONVECTION ACROSS MID MS VALLEY MAY TRY TO SHIFT
SOUTHEAST TOWARD THE OHIO VALLEY. NONETHELESS...SOME CONVECTION
WILL FILL IN ALONG THE FRONT AND FRONT APPEARS ON TRACK WITH
PREVIOUS FORECASTS... PERHAPS AN HOUR OR TWO QUICKER. WITH DRIER
AIR ALOFT THE BIGGER STORMS WILL BE PRIMED FOR POTENTIAL
DOWNBURSTS. WILL MENTION PSBL SEVERE IN WESTERN AND CENTRAL
COUNTIES THIS EVENING. WIND ALOFT IS NOT PARTICULARLY STRONG AND
WITH RELATIVELY DRY ATMOSPHERE AND WEAK/MODERATE DYNAMICS STORMS
WEAKENED AFTER SUNSET YESTERDAY AND WILL LIKELY DO THE SAME
TONIGHT.

MODELS CONTINUE TO SHOW NICE ENTRANCE REGION TO JET ALOFT INTO THE
DAY WEDNESDAY WITH SLOW PRESS OF COOLER AIR WHICH TYPICALLY
RESULTS IN SHOWERS BEHIND THE FRONT AND MODELS HAVE BEEN SHOWING
THIS FOR DAYS SO WILL NOT TRY TO TIME SHOWERS/STORMS OVERNIGHT
EXCEPT FOR THE ONSET ACROSS FAR EAST. HIGHER GROUND OVER NE OH/NW
PA WILL LIKELY CAUSE SHOWERS TO HANG ON THROUGH AT LEAST WED
MORN. SOME BREAKS IN THE CLOUDS NW OHIO DURING THE AFTRN BUT IT
MAY TAKE UNTIL LATE IN THE DAY TO REALLY START TO DRY UP AND EAT
AWAY AT CLOUD SHIELD.

MODEL GUIDANCE TEMPS SIMILAR AND REASONABLE. WHERE CLOUDS AND
SHOWERS HANG ON (NE OH/NW PA) WEDNESDAY TEMPS MAY ACTUALLY DROP
SOME BFR THEY STABILIZE OR RECOVER A FEW DEGREES LATE.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/...
NEXT SHORT WAVE PROGGED TO DROP QUICKLY ACROSS CENTRAL GREAT LAKES
TOWARD OH VALLEY WED NGT INTO THURSDAY. GFS SEEMS OVER
ENTHUSIASTIC WITH QPF ALTHOUGH CERTAINLY THINK THERE WILL BE SCT
SHOWERS. CENTER OF SHORT WAVE DROPS WEST AND SOUTH OF FCST AREA ON
THE WAY TOWARD CUTTING OFF. BEST UVV MAY MISS THE FCST AREA BUT
CANNOT RULE OUT A SHOWER OR TWO BUT ACTIVITY WILL LIKELY NOT GET
OUT OF HAND. LAKESHORE MAY BE PROTECTED AS COOLER AND MORE STABLE
AIR COMES OFF THE LAKE.

MIN TEMPS TRICKY WED NGT DEPENING ON AMOUNT OF CLOUDS. IF SKIES
WERE TO CLEAR AND WINDS DIMINISH THEN FROST BECOMES A POSSIBILITY.
WILL NOT MENTION IT FOR NOW AND TAKE A CLOSER LOOK WITH WED FCSTS.
ALSO WILL HAVE TO WATCH FOR FROST THURSDAY NIGHT ESPECIALLY
TYPICAL COLDER OUTLYING AREAS.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
SURFACE HIGH BUILDS IN FRIDAY AND ALTHOUGH UPPER LOW WILL BE JUST
SOUTH OF THE AREA I THINK WE WILL SEE MORE THAN ENOUGH DRYING AND
INCREASING STABILITY THAT ALL WE WILL HAVE TO DEAL WITH WILL BE
SOME FAIR WEATHER CUMULUS.

BACKDOOR TYPE FRONT STILL PROGGED TO DROP SOUTH ACROSS GREAT LAKES
SAT NGT INTO SUNDAY. NO SIGN THAT IT WILL BE MUCH OF A FRONT
ALTHOUGH TROUGH ALOFT REMAINS OVER THE NORTHEAST WHICH SHOULD ENABLE
ONE LAST PUSH OF CANADIAN HIGH PRESSURE SOUTHWARD FOR SUNDAY. IMPACT
WILL PROB BE MINIMAL AS THERE WILL BE LITTLE LOW LEVEL MOISTURE AND
WEAK AND SHALLOW CAA. IF SHORT WAVE ALOFT IS STRONGER OR IF
SHOWERS/STORMS DEVELOP OVER THE NW GRTLKS AND PROPOGATE SEWARD THEN
PERHAPS WE CAN GET SOME SHOWERS. WILL KEEP FCST DRY AND ADD A FEW
MORE CLOUDS SAT NGT INTO SUN. TEMPS MAY DROP A CATEGORY OR TWO
SUNDAY ESPECIALLY NEAR THE LAKE ERIE LAKESHORE. RETURN FLOW DEVELOPS
MONDAY AND APPEARS AS THOUGH IT WILL GO INTO MID WEEK NEXT WEEK
AHEAD OF DEEPENING BUT PROGRESSIVE TROUGH OVER PLAINS STATES. SHOULD
WARM UP STEADILY MON/TUE/WED (ESPECIALLY TUE AND WED) AND WILL FCST
TEMPS ABV SEASONAL NORMS AND GUIDANCE BY TUESDAY AS BOTH ECMWF AND
GFS SHOW STRONG WARM ADVECTION THROUGH THE PERIOD. RECENT WARM UPS
HAVE GOTTEN MAX TEMPS TO AROUND 80 OR IN THE 80S.

&&

.AVIATION /19Z TUESDAY THROUGH SUNDAY/...
