WILLARDWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Cleveland, OH wrote its last area forecast discussion before this severe thunderstorm warning went out at Sep 16, 3:15 PM EDT, 3 hours 25 minutes earlier.
Area forecast discussion, Sep 16, 3:15 PM EDT, 3 hours 25 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CLEVELAND OH 315 PM EDT THU SEP 16 2010 .SYNOPSIS... LOW PRESSURE JUST NORTH OF LAKE ERIE WILL MOVE EAST THIS EVENING AND DRAG A COLD FRONT THROUGH THE REGION. THE LOW WILL MOVE OFF THE MAINE COAST BY FRIDAY MORNING. HIGH PRESSURE WILL BUILD EAST ACROSS THE REGION FRIDAY. ANOTHER COLD FRONT WILL CROSS THE REGION LATE SATURDAY. && .NEAR TERM /THROUGH FRIDAY/... ENOUGH HEATING HAS TAKEN PLACE OVER WESTERN OHIO TO ALLOW FOR DESTABILIZATION AND CONVECTION TO INITIATE. STORMS HAVE GONE SEVERE. EXPECT THIS ACTIVITY TO PROGRESS ACROSS THE WESTERN HALF TO 2/3 OF THE AREA WITH SOME WEAKENING AS THE CONVECTION MOVES INTO MORE STABLE AIR. HOWEVER FARTHER EAST THE 0-1KM SHEAR IS HIGHER WITH LOWER LCL HEIGHTS WHICH MAY INCREASE THE POTENTIAL FOR TORNADOES. THIS ACTIVITY SHOULD HAVE SHIFTED EAST BY 00Z WITH A COLD FRONTAL PASSAGE. SOME LINGERING SHOWERS AND A FEW THUNDERSTORMS MAY PERSIST UNTIL ABOUT 03Z OVER THE EASTERN THIRD OF THE COUNTIES BEFORE COLD ADVECTION BRINGS COOLER AND MORE STABLE AIR INTO THE REGION. HAVE USED MAV GUIDANCE FOR MIN TEMPERATURES. TRANQUIL CONDITIONS ARE EXPECTED FRIDAY WITH HIGH PRESSURE GRADUALLY BUILDING INTO THE REGION WITH COOLER TEMPERATURES. && .SHORT TERM /FRIDAY NIGHT THROUGH MONDAY NIGHT/... .SHORT TERM /6 PM FRIDAY EVENING THROUGH MONDAY NIGHT/... HIGH PRESSURE AND DRY CONDITIONS OVER THE AREA FRI NIGHT WILL SHIFT EAST SAT TO ALLOW A COLD FRONT TO MOVE INTO THE AREA ABOUT SAT NIGHT. THE MODELS DIFFER ON THE TIMING OF THE FRONT SO STILL NOT SURE WHEN BEST CHANCE FOR SHOWERS WILL BE. BASED ON THIS WILL STAY FAIRLY CLOSE TO MIX OF PREVIOUS FORECAST AND GUIDANCE. ABOVE NORMAL HIGHS ON SAT WILL GET KNOCKED BELOW NORMAL FOR SUNDAY IN THE NORTH AND NE AS THE CLOUDS...PRECIP AND FRONT MOVES THROUGH. THE MODELS LOOK TO PRODUCE ENOUGH RIDGING DOWN IN THE AREA TO DRY THE AIRMASS ENOUGH TO PREVENT PRECIP FOR SUN NIGHT AND MON. THE FRONTAL BOUNDARY WILL LIFT NORTH THROUGH THE CWA MON NIGHT AND TUE AND COULD ACT AS A FOCUS FOR A FEW SHRA/TSRA TO DEVELOP ESPECIALLY FOR THE NORTHERN HALF OF THE AREA BUT WITH UPPER RIDGING OVER THE OHIO VALLEY WILL KEEP JUST SMALL/SLIGHT CHANCE. && .LONG TERM /TUESDAY THROUGH THURSDAY/... MODELS SOMEWHAT SIMILAR IN SOLUTIONS FOR THE LONG RANGE WITH LOW PRESSURE OVER THE NORTHERN GREAT LAKES AND THE COLD FRONT TRAILING TO THE SOUTHERN PLAINS. THERE IS A SLIGHT DIFFERENCE IN TIMING BUT BOTH INDICATING THE COLD FRONT MOVING TOWARD THE AREA ON WEDNESDAY SO AT THIS TIME HIGHLIGHTED THE FRONTAL PASSAGE WITH CHANCE POPS. INCREASED TEMPS A BIT AHEAD OF THE FRONT ON TUESDAY ESPECIALLY ACROSS SOUTHWESTERN AREAS. FOR WEDNESDAY STAYED CLOSE TO GUIDANCE VALUES WITH INCREASED CLOUD COVER AND CHANCES FOR SHOWERS AND THUNDERSTORMS ACROSS THE ENTIRE AREA. && .AVIATION /19Z THURSDAY THROUGH TUESDAY/... BIGGEST PROBLEMS IN THE TAF WILL BE STRENGTH AND TIMING OF BAND OF TSRA THAT WILL PROGRESS EAST ACROSS THE TAFS REST OF THIS AFTERNOON AND LOW MVFR/IFR THAT WILL WRAP ESE INTO THE AREA THIS EVENING. SOMEWHAT DIFFUSE NATURE OF THE COLD FRONT CROSSING THE AREA WILL MAKE IT HARD TO EXACTLY PIN DOWN THUNDERSTORMS AT TAF SITES NEXT 6 HOURS SO WILL LARGELY USE RADAR TRENDS AND LATEST HRRR PROGS TO DECIDE ON THIS. MODEL GUIDANCE STILL INDICATE MOIST LOW LEVELS TONIGHT ALONG WITH LOW CIGS AND VSBY'S SO WILL STAY FAIRLY CLOSE TO PREVIOUS FORECAST. CONDITIONS WILL IMPROVE FRI MORNING AS DAYTIME HEATING TAKES PLACE AND HIGH PRESSURE MOVES INTO WESTERN OHIO. THE EASTERN TAFS WILL BE SLOWER TO IMPROVE BUT STILL EXPECT AT LEAST HIGH END MVFR BY END OF TAF PERIOD. .OUTLOOK...NON VFR POSSIBLE LATE SATURDAY INTO SUNDAY. && .MARINE... LOW PRESSURE WILL MOVE ACROSS SOUTHERN LOWER MICHIGAN AND SOUTHEAST ONTARIO TODAY. SOUTHEAST WINDS ON THE LAKE EARLY TODAY AT 10 TO 20 KNOTS WILL TURN SOUTHWEST AT 20 TO 30 KNOTS AS THE LOW MOVES THROUGH. BEHIND THE LOW A COLD FRONT WILL DROP ACROSS THE LAKE TURNING WINDS TO THE NORTH OVERNIGHT TONIGHT...AND EVENTUALLY NORTH TO NORTHEAST ON FRIDAY AS THE LOW PULLS EAST AND HIGH PRESSURE BUILDS TOWARD THE LAKE. WILL ISSUE A SMALL CRAFT ADVISORY FOR TODAY...TONIGHT THROUGH EARLY AFTERNOON FRIDAY. THE NEXT SYSTEM TO AFFECT THE LAKE WILL COME SATURDAY NIGHT AS A COLD FRONT DROPS ACROSS THE LAKE. MODEL TIMING DIFFERENCES WITH THE COLD FRONT WILL SIDE WITH THE FASTER GFS AND EXPECT FRONT SATURDAY NIGHT. NAM IS SLOWER WITH PASSAGE AFTER DAYBREAK SUNDAY. THUS FOR SUNDAY WILL HAVE NORTH TO NORTHEAST WINDS IN THE WAKE OF THE FRONT VS THE NAM'S SOUTHWEST FLOW. EITHER WAY WOULD EXPECT POSSIBLE SMALL CRAFT ADVISORY CONDITIONS TO DEVELOP BEHIND THE FRONT SUNDAY. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...NONE. PA...NONE.
