Special Weather Statement, NWS Cleveland, OH

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
341 PM EDT SAT MAY 7 2016

.SYNOPSIS...
A COLD FRONT WILL CROSS THE AREA TONIGHT WITH A ROUND OF LIGHT
SHOWERS AND A CHANCE FOR THUNDERSTORMS. DRIER AIR WILL FILTER IN
BEHIND THE FRONT OVERNIGHT AS HIGH PRESSURE BECOMES ESTABLISHED FOR
SUNDAY. ON MONDAY A WARM FRONT WILL LIFT THROUGH THE OHIO VALLEY
INTO CENTRAL AND NORTHERN OHIO BY MONDAY NIGHT. THE FRONT WILL STALL
AND A SURFACE LOW ORIGINATING NEAR THE TEXAS PANHANDLE WILL TRACK
UP THE BOUNDARY TOWARDS OHIO THROUGH THURSDAY. HIGH PRESSURE WILL
RETURN BY THE END OF THE WEEK.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
EXPECTING SHOWERS AND THUNDERSTORMS TO BECOME MORE SCATTERED IN
COVERAGE THIS EVENING AHEAD OF A COLD FRONT. CURRENTLY THE FRONT IS
JUST A FEW COUNTIES EAST OF THE TOLEDO AREA. IF WE CAN GET UNSTABLE
ENOUGH AHEAD OF THE FRONT THERE IS STILL THE CHANCE FOR
THUNDERSTORMS. WITH DEW POINTS STILL IN THE UPPER 30/S AND LOW 40/S
ACROSS MUCH OF THE EASTERN THIRD...CHANCES AREN/T ESPECIALLY GREAT
THERE. HOWEVER...THE WIND HAS BEGUN TO INCREASE FROM THE SOUTH...SO
DEW POINTS COULD POTENTIALLY CLIMB 10 TO 15 DEGREES. THE WESTERN AND
ESPECIALLY THE CENTRAL THIRD HAVE A BETTER CHANCE OF GETTING A BIT
MORE UNSTABLE...AT LEAST ACCORDING TO THE MODEL GUIDANCE. ALREADY
THERE IS SOME HINT THAT THE WESTERN THIRD IS BECOMING MORE UNSTABLE
WITH DEVELOPING CAPE AND NEGATIVE LIFTED INDICES...BUT IT MAY BE TOO
LITTLE...TOO LATE. OVERALL SHOWERS SEEM TO BE A SAFER BET WITH JUST
A CHANCE OF THUNDER TONIGHT. BEHIND THE FRONT CONDITIONS WILL
IMPROVE AND THE SKY WILL BEGIN TO SCATTER AS DRIER AIR MOVES IN FROM
THE NORTH. OVERNIGHT LOWS WILL FALL INTO THE LOW AND MID 40/S WITH
DECREASING WIND.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY NIGHT/...
SUNDAY WILL BE DRY AND BREEZY WITH SURFACE PRESSURE RISES BEHIND THE
COLD FRONT. THE GRADIENT WILL TIGHTEN THROUGH THE AFTERNOON AND THE
WIND WILL INCREASE TO AROUND 10 TO 15 KNOTS SUSTAINED FROM THE WEST.
WITH AMPLE SUNSHINE AND MODERATING TEMPERATURES ALOFT...SURFACE
TEMPERATURES SHOULD HAVE NO PROBLEM GETTING INTO THE MID 60/S...AND
HIGHER INLAND. A FEW MORE CLOUDS ARE LIKELY IN THE FAR NE LATE
AFTERNOON AS A WEAK DISTURBANCE GLANCES THE AREA. HAD THE WIND BEEN
SOUTHERLY...WE WOULD EASILY BE TALKING ABOUT HIGHS 10 DEGREES
WARMER. FOR NOW...60/S WITH A MODERATE WEST WIND WILL HAVE TO DO.
SUNDAY OVERNIGHT DELAYED THE ONSET OF POPS AND CLOUDS IN THE FAR
SOUTH WITH THE DRIER AIR WEDGING FROM IN FROM THE NORTH.

MONDAY MORNING HIGH PRESSURE SHIFTS OFF TO THE EAST AND THE SUN WILL
BECOME FILTERED DURING THE AFTERNOON BY MID AND HIGH CLOUDS. THERE
IS SOME DISPARITY AMONG THE MODELS...BUT ALL AGREE AT SOME POINT IT
WILL RAIN. ALL SEEM TO SUGGEST A PRE-FRONTAL TROUGH EVENTUALLY
COMING UP INTO THE AREA AND HANDLE THE TIMING PRETTY WELL...BUT ONLY
THE GFS IS INDICATING RAIN. THE NAM AND ECMWF SHOW THE TROUGH
WASHING OUT BEFORE GETTING INTO NORTHERN OHIO. EARLIER FORECASTS HAD
CHANCE POPS IN THE SOUTHERN COUNTIES AS EARLY AS 8 AM. I AM GOING TO
DELAY THE RAIN AND DIAL BACK THE POPS...MORE IN LINE WITH THE NAM
AND ECMWF SOLUTIONS. IN FACT...MOST OF THE DAY LOOKS
DRY...ESPECIALLY IN THE NORTH AND EAST. THE MAIN WARM FRONT DOESN/T
ARRIVE UNTIL LATE MONDAY NIGHT INTO TUESDAY. BECAUSE OF THE
TIMING...THERE WON'T BE MUCH IF ANY SURFACE BASED INSTABILITY...BUT
THERE COULD BE ENOUGH ELEVATED CAPE FOR A RUMBLE OF THUNDER. TUESDAY
NIGHT A PUSH OF MOISTURE WILL ACCOMPANY ANOTHER SURFACE TROUGH AND
PIVOT NORTH ON THE HEELS OF THE WARM FRONT THAT WILL STALL
OUT/WEAKEN NORTH OF LAKE ERIE. THIS WILL INVITE ANOTHER ROUND OF
SHOWERS AND SOME THUNDERSTORMS TUESDAY NIGHT INTO WEDNESDAY...THOUGH
THE EARLY MORNING TIMING WILL PRECLUDE WIDESPREAD THUNDER.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
THE LONG TERM BEGINS ON TUESDAY WITH LOW PRESSURE IN THE CENTRAL
PLAINS AND A WARM FRONT THROUGH THE LOWER OHIO VALLEY. MODELS SHOW
THIS WARM FRONT LIFTS THROUGH OR NORTH OF THE AREA BY WEDNESDAY BUT
NOT BY MUCH AS DEEP MOISTURE REMAINS IN AND ACROSS THE AREA. LATE
WEDNESDAY AND WEDNESDAY NIGHT THE MODELS SHOW A WEAK UPPER RIDGE IN
THE AREA BUT MOISTURE REMAINS SO ITS NOT TO BE TRUSTED AT THIS
POINT. THURSDAY UPPER LOW PRESSURE WILL BE DIGGING ACROSS THE
DAKOTAS AND THE WESTERN LAKES. A SURFACE LOW WILL BE IN THE SAME
GENERAL AREA WITH A COLD FRONT SOUTHEAST THAT WILL MOVE ACROSS THE
OHIO VALLEY AND LOWER GREAT LAKES DURING THE DAY THURSDAY WITH
ANOTHER SWATH OF MOISTURE. THURSDAY NIGHT AND EARLY FRIDAY THERE
WILL POTENTIALLY BE A BREAK AHEAD OF ANOTHER APPROACHING COLD FRONT
DUE IN LATE FRIDAY.  MODELS DIVERGE INTO THE WEEKEND BUT NEITHER
PAINT A PRETTY PICTURE FOR THE AREA WITH UPPER LOW PRESSURE AND DEEP
MOISTURE OVER THE GREAT LAKES REGION. WILL HAVE CHANCE TO LIKELY
POPS MUCH OF THE LONG TERM AND HAVE PLACED THUNDER WHERE CONVECTIVE
INDICES SHOW A FAVORABLE SETUP. TEMPS NEAR NORMAL TO START BUT
EASILY BELOW NORMAL FOR THE WEEKEND.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
RADAR SHOWS SHOWERS TO OUR NORTH AND ROUGHLY ACROSS THE WESTERN
HALF OF THE AREA WITH MOVEMENT TO THE SOUTHEAST. WARM FRONT INTO
WESTERN OHIO WITH COLD FRONT TO OUR WEST IN SRN LWR MI TO NRN
INDIANA. MSAS LI'S -2 TO -3 ACROSS THE WEST AND NEAR ZERO EAST.
CONDITIONS REMAIN VFR ACROSS NRN OHIO AND NWRN PA WITH CIGS IN THE
WEST 8 TO 10KFT. EXPECTING SHOWERS TO FILL IN AS THEY CONTINUE TO
SPREAD EAST/SOUTHEAST ACROSS THE AREA ALTHOUGH THEY ARE HAVING A
ROUGH TIME WITH DEWPOINTS IN THE 40S AND 50S.  LI'S AND CAPES
SUGGEST THUNDER IS ALSO REASONABLE AS HEATING/MOISTURE INCREASE.
DO EXPECT A COUPLE HOUR PERIOD OF MVFR POST COLD FRONT BEFORE
CLEARING AS DRIER AIR MOVES BACK IN. EXPECT VFR SUNDAY.

OUTLOOK...NON-VFR POSSIBLE MONDAY NIGHT THROUGH THURSDAY.

&&

.MARINE...
WILL ISSUE A SMALL CRAFT ADVISORY FOR INCREASING NWLY WINDS BEHIND
AN APPROACHING COLD FRONT THIS EVENING AND OVERNIGHT.  WILL ALLOW
THE WEST END TO DROP OFF LATE TONIGHT BUT WILL CONTINUE HEADLINE
THROUGH SUNDAY ON THE EAST END AS WSW WINDS INCREASE AGAIN BUILDING
WAVES EAST HALF. HIGH PRESSURE WILL BE IN PLACE FOR MONDAY.THE HIGH
WILL WEAKEN TUESDAY AS LOW PRESSURE MOVES EAST THROUGH THE UPPER
MIDWEST.  A WARM FRONT WILL BE EAST FROM THE LOW INTO CENTRAL OHIO.
THE WARM FRONT WILL LIFT NORTH ONTO THE LAKE WEDNESDAY. A COLD FRONT
WILL FOLLOW ON THURSDAY. ANOTHER COLD FRONT WILL FOLLOW LATE
FRIDAY.
