AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
338 AM EDT SAT APR 30 2016

.SYNOPSIS...
LOW PRESSURE OVER THE CENTRAL PLAINS WILL MOVE NORTHEAST ACROSS
THE UPPER OHIO VALLEY AND LOWER GREAT LAKES ON SUNDAY. A WARM
FRONT WILL MOVE INTO THE AREA AHEAD OF THE LOW EARLY SUNDAY. A
COLD FRONT WILL FOLLOW SUNDAY AFTERNOON. HIGH PRESSURE WILL BUILD
IN ON MONDAY.


&&

.NEAR TERM /THROUGH TODAY/...
CLOUDS HAVE DISSIPATED ACROSS MUCH OF THE AREA THROUGH THE EARLY
OVERNIGHT HOURS AS HIGH PRESSURE AND DRIER AIR MOVED IN FROM THE
NORTH. SATELLITE SHOWS WIDESPREAD CLOUDS JUST TO OUR WEST HOWEVER
IN OVERRUNNING/ISENTROPIC LIFT AHEAD OF LOW PRESSURE MOVING
THROUGH THE CENTRAL PLAINS. EXPECT THIS CLOUD COVER TO SPREAD
INTO/ACROSS THE AREA THROUGH THE EARLY MORNING HOURS. RAIN NOT ON
KCLE RADAR YET BUT A REGIONAL LOOK SHOWS RAIN ACROSS KY/SRN IN/SRN
IL MOVING NORTHEAST. HRRR TIMING LOOKS REASONABLE WITH THE RAIN
GETTING INTO OR CLOSE TO THE SWRN TIER OF COUNTIES FROM KFDY-KMNN
AROUND 15-16Z TIME FRAME AND KCLE 19-20Z. KEPT POPS AT SLIGHT
CHANCE THROUGH THE MORNING SOUTHWEST WITH DRY CONDITIONS
ELSEWHERE. THROUGH THE AFTERNOON WILL TAKE POPS TO CATEGORICAL
ALONG AND WEST OF AN ERIE TO STARK COUNTY LINE. FURTHER EAST TO
NWRN PA WILL HAVE CHANCE OR SLIGHT CHANCE. HELD TEMPS TO A 55 TO
63 RANGE NORTHWEST TO SOUTHEAST.

&&

.SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT/...
EARLY TONIGHT THE WARM FRONT WILL MOVE INTO THE AREA FROM THE
SOUTHWEST AS THE LOW REACHES NEAR THE CENTRAL LAKESHORE. GIVEN
THAT THE LOW WILL TRACK VERY NEAR THE REGION SUNDAY MORNING...THE
MODEL DIFFERENCES REMAIN SIGNIFICANT...MORE SO FOR TEMPERATURES
THAN PRECIP. FOR NOW HAVE SIDED MORE WITH THE SREF SOLUTION...ITS
PATH ALLOWING FOR MILDER AIR TO REACH FURTHER NORTH INTO THE AREA
SUNDAY BEFORE THE COLD FRONT DROPS THROUGH. FOR TONIGHT RAIN
SHOULD BE ONGOING SO WILL HAVE CATEGORICAL POPS TAPERING FROM THE
WEST AFTER MIDNIGHT AS DRIER AIR WORKS IN. SUNDAY...MODEL
DIFFERENCES CONTINUE WITH THE GFS DERIVED POPS MOSTLY IN THE
LIKELY CATEGORY WHILE THE NAM IN CHANCE TO SLIGHT CHANCE. AGAIN
HAVE SPLIT THE DIFFERENCE WITH MAINLY CHANCE POPS. NO JOY SUNDAY
NIGHT WITH THE GFS SUGGESTING STRONGLY THAT WRAP AROUND MOISTURE
GETS INTO THE AREA WITH CAT POPS. THE NAM...NOT SO MUCH. WILL HAVE
LIKELY POPS EAST/NORTHEAST WHERE MOISTURE WILL BE BEST...AND
CHANCE POPS ELSEWHERE. MONDAY WILL HANG INTO A SLIGHT CHANCE POP
SOUTHEAST BUT EXPECT DRY FOR THE MOST PART AS THE SYSTEM EXITS NEW
ENGLAND AND HIGH PRESSURE BUILDS INTO THE AREA. FOR NOW WILL
CONTINUE DRY THROUGH TUESDAY HOWEVER ANOTHER TROUGH APPROACHES
FROM THE NORTH DURING THE AFTERNOON. BEST CHANCE FOR PRECIP WILL
COME TUESDAY NIGHT BUT WILL WAIT ANOTHER RUN OR TWO FOR IMPROVED
CONSISTENCY BEFORE COMMITTING MORE THAN A SLIGHT CHANCE. TEMPS
THROUGH THE SHORT TERM NEAR TO BELOW NORMAL.

&&

.LONG TERM /WEDNESDAY THROUGH FRIDAY/...
THE ENTIRE LONG TERM WILL BE INFLUENCED BY A TROUGH THAT WILL DIG
FROM THE GREAT LAKES TO THE SOUTHEAST U.S. THE ONLY DAY WE ARE
EXPECTED TO BE NEAR NORMAL IS WEDNESDAY...WITH A COLD FRONT THAT
WILL BRING TEMPERATURES BACK DOWN BELOW NORMAL FOR THE REMAINDER OF
THE WEEK. WILL HAVE TO KEEP SOME CHANCES FOR SHOWERS IN THE FORECAST
WITH THE COOL UPPER TROUGH AND CYCLONIC FLOW LINGERING FOR SEVERAL
DAYS.

&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
REGION IN THE GAP BETWEEN SYSTEMS WITH CLEAR SKIES TO START. STILL
SOME VFR STRATUS IN NW OH AND MVFR STRATUS IN NW PA/EASTERN OHIO.
THESE MAY EXPAND INTO TOL/FDY/YNG/ERI OVER THE NEXT SEVERAL HOURS.
WITH THE LATE CLEARING...MAY GET BR/FG TO DEVELOP FOR MFD/CAK.
NEXT SYSTEM APPROACHES FOR SATURDAY. PRIMARILY VFR TO START WITH
LOWERING CEILINGS AS WE GO THROUGH THE AFTERNOON. IFR FOR THE
EVENING WITH RAIN. THUNDER A SMALL POSSIBILITY ACROSS THE FAR
SOUTH. MODELS STILL NOT IN VERY GOOD AGREEMENT WITH THE TRACK OF
THE LOW OUT OF MISSOURI ACROSS OHIO. EXACT TRACK WILL DETERMINE
NOT ONLY WIND DIRECTION FOR LATE SATURDAY NIGHT...BUT ALSO WHETHER
THE NON VFR CEILINGS CAN LIFT.

OUTLOOK...NON-VFR SATURDAY NIGHT. SOME BREAKS IN THE NON VFR
SUNDAY FAR SOUTH. NON VFR MONDAY...PRIMARILY NE OH/NW PA. NON VFR
WEDNESDAY.

&&

.MARINE...
WINDS WILL BECOME NORTHEAST TODAY AND INCREASE TO THE POINT THAT WE
WILL BE ON THE VERGE OF NEEDING A SMALL CRAFT ADVISORY TOWARD THE
ISLANDS LATE THIS AFTERNOON AND TONIGHT. LOW PRESSURE WILL TRACK
ACROSS NORTHERN OHIO SUNDAY...WITH WINDS ON THE LAKE BACKING TO THE
NORTHWEST BY MONDAY MORNING. HIGH PRESSURE SETTLES THE LAKE
TUESDAY...BUT A CLIPPER TYPE LOW WILL TAKE A COLD FRONT ACROSS LAKE
ERIE ON WEDNESDAY. SOUTHWEST WINDS TUESDAY NIGHT WILL
INCREASE...WITH A CHANCE OF 15 TO 20 KNOTS. FOR NOW FORECAST IS
LESS.

&&

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