NWS Cleveland, OH wrote its last area forecast discussion before the first event at Jul 27, 2:15 PM EST, 2 hours earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CLEVELAND OH 315 PM EDT SUN JUL 27 2014 .SYNOPSIS... A LOW NEAR DETROIT WILL MOVE INTO NEW ENGLAND THROUGH MONDAY THEN DRIFT NORTH INTO EASTERN CANADA BY THE MIDDLE OF THE WEEK. HIGH PRESSURE OVER THE PLAINS WILL SPREAD UP THE OHIO VALLEY THURSDAY THEN REMAIN OVER THE AREA INTO THE WEEKEND WHILE UPPER LEVEL LOW PRESSURE IS STALLED OVER THE REGION. && .NEAR TERM /UNTIL 6 AM MONDAY/... A VIGOROUS S/W TROUGH WILL MOVE ESE ACROSS THE CWA TONIGHT. STRONG DYNAMICS WITH THE TROUGH WILL ACT ON UNSTABLE AIR TO LIKELY PRODUCE NUMEROUS STRONG TO SEVERE STORMS...ISOLATED TORNADOES ARE EVEN POSSIBLE. RAIN MAY BE LOCALLY HEAVY...SO SOME LOCATIONS THAT SEE REPEAT TSRA IN A SHORT PERIOD OF TIME COULD START TO SEE SOME FLOODING ISSUES BUT DRY WEATHER OVER MOST OF THE PAST WEEK SHOULD MEAN ANY FLOODING WILL BE ISOLATED. GENERAL AREA OF BIGGEST CONCERN FOR FLOODING WILL BE THE SNOWBELT WHERE WRAP SHRA WILL BE MOST CONCENTRATED FOR THE LATTER PART OF THE NIGHT THRU MON MORNING. COOLER AIR MOVING IN FROM THE NW DURING THE SECOND HALF OF THE NIGHT SHOULD START TO STABILIZE THE AIRMASS TO END THE THUNDER THREAT FROM WEST TO EAST. && .SHORT TERM /6 AM MONDAY THROUGH WEDNESDAY NIGHT/... WRAP SHRA ARE SHOWN TO AFFECT THE SNOWBELT AREA IN THE MORNING BECOMING LESS NUMEROUS DURING THE DAY AS THE S/W MOVES OFF TO THE EAST TAKING THE DEEPER MOISTURE OUT OF THE AREA. A LITTLE THUNDER IS POSSIBLE MONDAY BUT MOST PLACES SHOULD JUST SEE SHRA SO WILL CONTINUE TO NOT MENTION TSRA. TEMPS WILL BE NOTICEABLY COOLER MON WITH HIGHS MOSTLY FROM THE UPPER 60S TO LOWER 70S. MARGINAL LAKE EFFECT CONDITIONS MAY ALLOW A FEW SHRA TO HANG AROUND IN THE SNOWBELT MON NIGHT INTO TUE MORNING. LATER TUE...ANOTHER UPPER S/W DROPS INTO THE AREA SHARPENING THE MAIN TROUGH WHILE INDUCING A SURFACE TROUGH. THERE SHOULD BE AN OVERALL PICKUP IN SCT SHRA LATER TUE INTO TUE NIGHT. WILL MAKE THE THREAT FOR SHRA MORE WIDESPREAD ACROSS THE CWA AND CONTINUE THIS THRU WED AS ANOTHER OF A SERIES OF S/W'S WILL DIVE INTO THE MAIN TROUGH TO KEEP IT OVER THE AREA. TEMPS TUE AND WED WILL STAY BELOW NORMAL && .LONG TERM /THURSDAY THROUGH SUNDAY/... HARD TO GET TOO SPECIFIC IN THE LONG TERM PORTION OF THE FORECAST. THE TROUGH ALOFT IS PROGGED TO DEEPEN MID WEEK AND THEN LINGER. THE GFS HAS BACKED AWAY FROM THE PREVIOUS SOLUTION OF A LONG LASTING CLOSED LOW BUT ALL OF THE MODELS MAINTAINS AN UNSEASONABLY DEEP TROUGH OVER THE GREAT LAKES THROUGH NEXT WEEKEND AND BEYOND. IT WILL BE DIFFICULT TO PICK OUT A DAY WITH NO CHANCE OF SHOWERS...PERHAPS AT NIGHT WHEN CONVECTIVE PROCESSES DIMINISH. NOT GOING TO GO WITH ANYTHING MORE THAN A "CHANCE" OF SHOWERS AT THIS POINT GIVEN THE LACK OF DETAILS ALTHOUGH AT SOME POINT A TROUGH OR SHORT WAVE WILL ROTATE THROUGH AND THERE WILL LIKELY BE MORE ORGANIZED ACTIVITY. TEMPERATURES WILL DEPEND A LOT ON THE AMOUNT OF CLOUDS AND SHOWERS BUT THE PATTERN SHOULD BRING TEMPERATURES AT LEAST A FEW DEGREES BELOW NORMAL AND PERHAPS AS MUCH AS 5 OR 6 DEGREES BELOW NORMAL. DEWPOINTS WILL LIKELY BEGIN TO CREEP UP JUST A BIT SO THE AIR MASS WILL LOOSE ITS CRISP AND COOL FEELING AND PROBABLY START TO GET A DAMP AND COOL FEELING. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... THUNDERSTORMS WILL CONTINUE TO EXPAND THIS AFTERNOON AND LIKELY MERGE INTO A LARGE CLUSTER OF SHOWERS AND STORMS BY EVENING ACROSS THE EASTERN GREAT LAKES. WIND DIRECTION WILL BE TRICKY AT THE TAF FORECAST SITES DEPENDING ON THE OUTFLOW OF NEARBY THUNDERSTORMS BUT SHOULD EVENTUALLY BECOME NORTH TO NORTHWEST LATE TONIGHT AND MONDAY MORNING AS A COLD FRONT DROPS ACROSS THE AREA. CEILINGS WILL BECOME IFR AFTER THE FRONTAL PASSAGE. OUTLOOK...NON VFR IN SHOWERS TUESDAY THROUGH FRIDAY. && .MARINE... THE COLD FRONT SHOULD SLIDE ACROSS LAKE ERIE TONIGHT ALONG WITH A SURFACE LOW. IN THE MEAN TIME WE WILL HAVE OUTFLOW BOUNDARIES FROM THUNDERSTORMS OVER THE WESTERN AND CENTRAL BASIN OF THE LAKE SO THE WIND WILL BE VARIABLE AND PERHAPS GUSTY AT TIMES THIS EVENING. STILL NOT SURE EXACTLY WHERE THE SURFACE LOW WILL TRACK...PROBABLY ACROSS EASTERN LAKE ERIE... SO THE WIND SHIFT MAY TAKE UNTIL EARLY MONDAY ON THE EAST END OF THE LAKE. SMALL CRAFT ADVISORIES WILL BE NEEDED MONDAY AS THE COLD ADVECTION INCREASES BEHIND THE COLD FRONT AND IT WILL NOT BE A GOOD DAY FOR RECREATIONAL BOATING. WATERSPOUTS ARE ALSO POSSIBLE MONDAY...PERHAPS INTO TUESDAY... AS THE AIR ALOFT WILL BE UNSEASONABLY COOL. A LARGE AREA OF HIGH PRESSURE OVER THE CENTRAL PORTION OF THE COUNTRY WILL TAKE ALL WEEK TO MOVE EAST AS THE TROUGH ALOFT DEEPENS. THE END RESULT WILL BE A SURFACE FLOW VARYING FROM SOUTHWEST TO NORTHWEST MUCH OF THE WEEK. EACH TROUGH OF LOW PRESSURE THAT CROSSES THE LAKE CAN RESULT IN A PERIOD OF HIGHER WINDS AND WAVES. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...NONE. PA...NONE. MARINE...NONE. && SYNOPSIS...ADAMS NEAR TERM...ADAMS SHORT TERM...ADAMS LONG TERM...KOSARIK AVIATION...KOSARIK MARINE...KOSARIK
