NWS Cleveland, OH wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 10, 8:06 PM EDT, 1 hour 15 minutes earlier.

Area forecast discussion, Aug 10, 8:06 PM EDT, 1 hour 15 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
806 PM EDT MON AUG 10 2015

.SYNOPSIS...
LOW PRESSURE OVER THE AREA WILL MOVE OFF TO THE
NORTHEAST TONIGHT PULLING A COLD FRONT EAST OF THE REGION.  HIGH
PRESSURE OVER THE UPPER PLAINS TUESDAY WILL MOVE UP THE OHIO VALLEY
WEDNESDAY INTO THURSDAY. A WEAK COLD FRONT SHOULD MOVE THROUGH THE
REGION LATE FRIDAY THEN HIGH PRESSURE WILL REBUILD OVER THE AREA FOR
THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
SURFACE LOW PRESSURE CONTINUES TO MOVE EAST ACROSS THE STATE OF
OHIO. SHOWERS AND THUNDERSTORMS ASSOCIATED WITH THE LOW PRESSURE
SYSTEM WILL CONTINUE TO MOVE EAST AS WELL THROUGH THE REST OF THE
EVENING. MAIN LINE FROM LORAIN COUNTY SOUTHWEST THROUGH WYANDOT
COUNTY ARE ALONG THE AXIS OF THE WARM FRONT TO THE NORTH OF THE
LOW AND COLD FRONT TO THE SOUTHWEST. ACTIVITY APPEARS TO BE
WEAKENING AS SUN BEGINS TO DROP LOWER ON THE HORIZON. EXPECTING
DIMINISHING ACTIVITY IN THE WAKE OF THE LOW PRESSURE SYSTEM
OVERNIGHT.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY NIGHT/...
CONDITIONS FOR LAKE
ENHANCED SHRA WILL IMPROVE FOR LATER TUE THRU WED AS THE UPPER
TROUGH SLOWLY CROSSES LAKE ERIE AND WRAP MOISTURE DROPS SE ACROSS
THE AREA. THE MODELS DIFFER SOME ON WHEN SOME BETTER MID LEVEL
MOISTURE DROPS INTO THE AREA TO HELP MAKE THE THREAT FOR SHRA A
LITTLE MORE WIDESPREAD BUT ON AVERAGE IT LOOKS TO BE TUE NIGHT.

HIGH PRESSURE WILL PUSH UP THE OH VALLEY LATE WED INTO THU. THIS
WILL BRING DRIER AIR AND MORE SUBSIDENCE WHICH SHOULD BRING THE LAKE
ENHANCED SHRA TO AN END WED EVE. SOME OF THE MODELS STILL SHOW WARM
ADVECTION PRECIP OVER THE LAKE MICHIGAN AREA WED NIGHT THAT TRIES TO
SPREAD ESE TO NEAR LAKE ERIE LATE WED NIGHT INTO THU. WILL SPREAD
SOME SLIGHT CHC POPS INTO LAKE ERIE FOR THU FOR THIS POSSIBILITY.

A WEAK COLD FRONT MOVES SE CLOSE ENOUGH TO THE AREA TO POSSIBLY
PROVIDE FOR SOME CONVECTION IN THE NW AND AROUND LERI LATE IN THE
NIGHT.

TEMPS WILL BOTTOM OUT ABOUT 10 DEGREES BELOW NORMAL FOR WED THEN
START TO MODERATE A LITTLE WARMER FOR THU AS THE COLD ADVECTION
TURNS TO WARM ADVECTION.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
THE MODELS HAVE BEEN
CONSISTENT WITH A WEAKENING COLD FRONT LATE IN THE WEEK. THE WINDOW
SEEMS BE WIDENING ON THE TIMING...WITH THE GFS TRENDING FASTER ON
FRIDAY AND THE ECMWF STUBBORNLY SLOW LATER FRIDAY NIGHT. THE GEM IS
IN BETWEEN AS IT ALWAYS SEEMS TO BE. WITH THE NORTHWEST FLOW
ALOFT... THE FASTER FRONTAL PASSAGE IS A POSSIBILITY BUT THIS TIME
OF YEAR FRONTS TYPICALLY SEEM TO BE SLOWER THAN PROGGED...HENCE THE
LACK OF CONFIDENCE. WHILE THE WEAKENING FRONT DOES NOT APPEAR TO
WARRANT A HIGH POP OR A LONG DURATION OF POP...WE WILL CONTINUE TO
SPREAD OUT A LOW POP FRIDAY INTO SATURDAY GIVEN THE UNCERTAINTY ON
THE TIMING.

THE HOT RIDGE ALOFT IS IMPRESSIVE OUT WEST AND SOME OF THE MODELS
KEEP PREDICTING THAT THE RIDGE ALOFT WILL TRY TO NOSE INTO THE
WESTERN GREAT LAKES EARLY NEXT WEEK. IT WOULD ALMOST CERTAINLY BE
SHORT LIVED BUT PERHAPS WE CAN SEE A COUPLE OF DOG DAYS THE FIRST
HALF OF NEXT WEEK. AS ALWAYS...WILL NOT GO WHOLE HOG ON ANY SCENARIO
JUST YET BUT WILL CONTINUE TO FORECAST TEMPS ABOVE NORMAL EARLY NEXT
WEEK. ANOTHER WEAKENING FRONT SEEMS AS THOUGH IT MAY DRIFT INTO THE
AREA ON MONDAY AND COULD BE A FLY IN THE OINTMENT BUT IF THE RIDGE
IS BUILDING THEN THE FRONT MAY NOT MAKE IT. WILL JUST MENTION A
"SLIGHT CHANCE" OF SHOWERS/STORMS FOR NOW.

&&

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
CLUSTER OF THUNDERSTORMS AHEAD OF AN APPROACHING COLD FRONT WILL
PUSH SOUTHEAST ACROSS THE AREA THROUGH 02Z. THE STRONGEST
THUNDERSTORMS WILL CONTAIN VERY HEAVY RAINFALL AND LOW IFR
VISIBILITIES. WEST TO EAST ORIENTED AREA OF HEAVY THUNDERSTORMS
LOOKS TO IMPACT YNG THROUGH NEARLY 02Z. WINDS MAY ALSO SHIFT TO
THE NORTHWEST WITH GUSTS TO 30 KNOTS POSSIBLE. WINDS MAY BRIEFLY
SHIFT BACK TO THE WEST BEFORE FINALLY SETTLING INTO A NORTHWEST
DIRECTION FOR THE REMAINDER OF THE TAF CYCLE BY 06Z. IFR
CONDITIONS ARE EXPECTED TO DEVELOP MOST SITES BETWEEN 06-10Z AND
LINGER THROUGH APPROXIMATELY 16Z. CLOUDS WILL GRADUALLY LIFT
THROUGH THE DAY ON TUESDAY.

OUTLOOK...A CHANCE OF NON-VFR CONDITIONS FRIDAY NIGHT INTO
SATURDAY IN SHOWERS AND THUNDERSTORMS.

&&

.MARINE...
THE COLD FRONT WILL CROSS LAKE ERIE EARLY TONIGHT. NOT
MUCH WIND ACCOMPANYING THE FRONT ITSELF BUT THUNDERSTORM WINDS COULD
BE AN ISSUE. PRETTY GOOD GRADIENT BETWEEN THE BUILDING HIGH PRESSURE
FROM THE WEST AND THE LOW OVER THE NORTHEAST TUESDAY INTO WEDNESDAY.
THE GUIDANCE DOES NOT GIVE MUCH WIND BUT I WOULD BE WILLING TO BET
THAT WE WILL NEED A SMALL CRAFT ADVISORY AT SOME POINT TUESDAY INTO
WEDNESDAY. PROBABLY LATER TUESDAY INTO WEDNESDAY...BUT A LITTLE TOO
EARLY TO PIN IT DOWN.

THE SURFACE HIGH SHOULD SLIDE ACROSS THE AREA THURSDAY. A SOUTHWEST
FLOW WILL DEVELOP ON THE BACK SIDE OF THE HIGH ON FRIDAY AND WINDS
WILL PROBABLY BE RATHER BRISK AHEAD OF THE NEXT COLD FRONT WHICH
SHOULD APPROACH LAKE ERIE BY LATE FRIDAY. THE FRONT SHOULD SLIDE
SOUTH OF LAKE ERIE ON SATURDAY AND THERE DOES NOT SEEM LIKE MUCH
WIND BEHIND THE WEAKENING FRONT AT THIS TIME.
