AREA FORECAST DISCUSSION  
NATIONAL WEATHER SERVICE CLEVELAND OH  
227 PM EDT MON MAR 31 2025  
   
SYNOPSIS  
 
A COLD FRONT WILL EXIT TO THE EAST THIS MORNING AS LOW PRESSURE  
TRACKS NORTHEAST ACROSS LOWER MICHIGAN TO QUEBEC. HIGH PRESSURE WILL  
BUILD EAST ACROSS THE GREAT LAKES REGION TONIGHT THROUGH TUESDAY.  
ANOTHER LOW PRESSURE SYSTEM WILL ENTER THE UPPER MIDWEST MID-WEEK  
LIFTING A WARM FRONT NORTH ACROSS THE LOCAL AREA ON WEDNESDAY BEFORE  
DRAGGING A COLD FRONT EAST ON WEDNESDAY NIGHT.  
 
 
   
NEAR TERM /THROUGH TUESDAY/  
 
THE COLD FRONT IS THROUGH THE FORECAST AREA EARLY THIS AFTERNOON  
AND TEMPERATURES HAVE COOLED OR REMAINED STEADY IN THE 40S.  
SOME ISOLATED SHOWERS CONTINUE TO RIPPLE THROUGH NORTHEAST OHIO  
AND NORTHWEST PENNSYLVANIA, BUT THE OVERALL CHANCES OF  
MEASURABLE PRECIPITATION FROM THIS POINT FORWARD ARE LOW.  
OVERCAST CONDITIONS WILL CONTINUE THROUGH TONIGHT INTO TUESDAY  
WITH TEMPERATURES COOLING WITH THE DIURNAL CYCLE AND COLD AIR  
ADVECTION ACROSS THE REGION. LOW TEMPERATURES TONIGHT WILL BE  
NEAR AND BELOW FREEZING WITH UPPER 20S AND LOWER 30S. DID DIG  
INTO ANY SNOW CHANCES FOR TONIGHT WITH COLD FLOW OFF LAKE ERIE  
AND INTO NE OH/NW PA. OVERALL, THE LACK OF DEEP MOISTURE ACROSS  
THE REGION WILL MAKE SNOW GROWTH DIFFICULT IN THE ATMOSPHERE.  
HOWEVER, THERE IS SOME MOISTURE WITH THE CLOUD DECK AROUND 2000  
FT, SO A STRAY FLAKE TONIGHT COULD HAPPEN, BUT ANY MEASURABLE  
SNOW CHANCES SEEM NIL AT THIS TIME AND HAVE NO MENTIONABLE POPS.  
HIGH PRESSURE BUILDING FROM THE NORTH WILL CONTINUE TO BRING  
DRYING CONDITIONS TO THE REGION AND EXPECT THE OVERCAST  
CONDITIONS TO SCOUR OUT BY AFTERNOON. TEMPERATURES WILL REMAIN  
ON THE COLD SIDE OF NORMAL WITH HIGHS IN THE UPPER 30S TO MID  
40S FOR TUESDAY.  
 
 
   
SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/  
 
HIGH PRESSURE WILL MOVE EASTWARD TOWARDS SOUTHERN QUEBEC TUESDAY  
EVENING AND CONTINUE TO DOMINATE OUR WEATHER PATTERN THROUGH MOST OF  
THE OVERNIGHT. OUR WINDS WILL SHIFT FROM THE EAST BY TUESDAY EVENING  
AND MAY INCREASE 10 TO 20 MPH DUE TO A PRESSURE GRADIENT WITH A  
STRONG LOW PRESSURE SYSTEM DEVELOPING ACROSS THE CENTRAL CONUS AND  
MIDWEST. TEMPERATURE WILL BE COOLEST TUESDAY EVENING FOLLOWED BY A  
SLOW CLIMB DURING THE LATE NIGHT HOURS. BY EARLY WEDNESDAY MORNING,  
A STRONG WARM FRONT WILL SURGE NORTHWARD ACROSS THE AREA IN RESPONSE  
TO A STRONG LOW PRESSURE THAT WILL TRACK THROUGH THE UPPER MIDWEST  
DURING THE DAY. THE 850MB LEVEL FLOW WILL BE CRANKING WEDNESDAY  
MORNING UP TO 65+ KNOTS WHICH WILL QUICKLY ADVECT IN WARMTH AND  
MOISTURE WITH THE WARM FRONT. MORNING AND MIDDAY RAIN SHOWERS WILL  
BE LIKELY WITH THE WARM FRONT LIFTING THROUGH. A COUPLE ISOLATED,  
ELEVATED THUNDERSTORMS MAY ALSO BE POSSIBLE WITH THE WARM FRONT.  
MODEL GUIDANCE INDICATES BETWEEN 200 AND 400 J/KG OF MUCAPE MAY  
DEVELOP AND HELP IN THE DEVELOP OF ISOLATED CONVECTION. THAT INITIAL  
ROUND OF RAIN WILL MOVE OUT DURING THE AFTERNOON HOURS. CONSIDERABLE  
CLOUDINESS WILL LIKELY CONTINUE FOR THE REST OF THE AFTERNOON BUT  
STRONG WARM ADVECTION IN THE LOW LEVELS WILL CAUSE TEMPERATURES TO  
REACH THE MIDDLE 60S TO LOWER 70S DURING THE LATE AFTERNOON.  
 
THE SPRING-LIKE WARMTH WEDNESDAY AFTERNOON WILL BE THE ENERGY FOR  
OUR NEXT ROUND OF POSSIBLE SEVERE WEATHER AND THUNDERSTORMS. LOW  
PRESSURE WILL TRACK THROUGH THE UPPER GREAT LAKES WEDNESDAY NIGHT. A  
TRAILING COLD FRONT WILL MOVE INTO THE LOWER GREAT LAKES AND OHIO  
VALLEY REGION LATE WEDNESDAY AFTERNOON AND KNOCKING ON OUR NWOH AREA  
WEDNESDAY EVENING. MODEL GUIDANCE SHOW THAT THIS COLD FRONT WILL  
SLOWLY MOVE THROUGH WEDNESDAY NIGHT INTO EARLY THURSDAY MORNING.  
STRONG TO SEVERE STORMS WILL BE POSSIBLE WITH THE GREATEST POTENTIAL  
ACROSS NWOH. SPC HAS MOST OF NWOH IN AN ENHANCED RISK WITH A LEVEL 3  
OUT OF 5 FOR SEVERE WEATHER. THE REST OF THE AREA IS IN A SLIGHT  
RISK OR LEVEL 2 OUT OF 5 THREAT FOR THE SEVERE STORM POTENTIAL. ALL  
MODES OF SEVERE WEATHER WILL BE POSSIBLE. THERE WILL BE VERY STRONG  
EFFECTIVE SHEAR OF 60 TO 80 KNOTS AND HODOGRAPHS LOOK ADEQUATE FOR  
ROTATING UPDRAFTS. DAMAGING WIND GUSTS, LARGE HAIL, AND AN ISOLATED  
TORNADO THREAT WILL BE THE SEVERE HAZARDS WEDNESDAY EVENING. THE  
CONVECTION WILL SLOWLY WEAKEN AS IT MOVES INTO NEOH AND NWPA LATER  
IN THE NIGHT AS THE ATMOSPHERIC DYNAMICS AND LESS CAPE FURTHER  
EASTWARD. DUE TO THIS FRONTAL BOUNDARY SLOWING DOWN AS IT TRACKS  
THROUGH, THERE IS THE POTENTIAL FOR HEAVY RAINFALL. THE AVERAGE  
GUIDANCE FOR QPF WEDNESDAY AFTERNOON THROUGH THURSDAY MORNING  
INDICATES RAINFALL TOTALS WILL BE 1 TO 2 INCHES WITH ISOLATED HIGHER  
AMOUNTS POSSIBLE. THE HEAVIEST RAINFALL AXIS MAY BE OVER NWOH INTO  
CENTRAL OHIO WITH THIS PARTICULAR ROUND.  
 
MODEL GUIDANCE IS IN GOOD AGREEMENT THAT THE FRONT WILL STALL OUT  
NEAR CENTRAL OHIO ON THURSDAY. WE WILL CONTINUE WITH LIKELY POPS  
THURSDAY INTO THURSDAY NIGHT FOR MOST OF THE AREA WITH THE HIGHEST  
POPS CLOSER TO CENTRAL OHIO. THE STALLED OUT FRONT BASICALLY  
BECOMES PARALLEL WITH THE MID LEVEL FLOW THURSDAY INTO THE  
OVERNIGHT. ANOTHER WEAK DISTURBANCE WILL RIDE ALONG THAT FRONTAL  
BOUNDARY AND HELP DEVELOP MORE ROUNDS OF SHOWERS AND POTENTIAL  
CONVECTION WITH A HEAVY RAINFALL THREAT. THE GREATER THREAT MAY BE  
SOUTH OF OUR CWA IN SOUTHERN AND CENTRAL OHIO BUT CLOSE ENOUGH TO BE  
MINDFUL OF.  
 
 
   
LONG TERM /FRIDAY THROUGH MONDAY/  
 
WE WILL STILL BE DEALING WITH CLOUD COVER AND CHANCES FOR SCATTERED  
RAIN SHOWERS ON FRIDAY NORTH OF THE STALLED FRONT THAT WILL BE  
LOCATED NEAR THE OHIO RIVER. A LIGHT NORTHERLY FLOW WILL MAKE FOR A  
TEMPERATURE GRADIENT ACROSS THE AREA FRIDAY AFTERNOON. CLOSER TO THE  
LAKE, TEMPS WILL BE STUCK IN THE LOWER TO MID 50S. MILDER TEMPS WILL  
BE FURTHER SOUTH INTO OUR CENTRAL OHIO AREA WITH LOWER 60S FOR  
FRIDAY'S HIGH. THE STALLED FRONT WILL HANG OUT NEARBY OR SOUTH OF  
OUR AREA THROUGH SUNDAY MORNING WITH MULTIPLE ROUNDS OF RAINFALL  
POSSIBLE. RAINFALL TOTALS MAY ADD UP FROM THE MID WEEK THROUGH THE  
WEEKEND TO CAUSE SOME FLOODING AND HYDRO CONCERNS ON OUR LOCAL  
RIVERS. THE WEATHER PATTERN WILL CHANGE IN A BIG WAY BY NEXT WEEKEND  
INTO EARLY NEXT WEEK. A VERY LARGE AND DEEP UPPER LEVEL TROUGH WILL  
DIG FROM THE HUDSON BAY REGION INTO THE GREAT LAKES AND OHIO VALLEY  
SUNDAY INTO MONDAY. WE WILL SEE A BIG COOL DOWN AS THIS UPPER LEVEL  
TROUGH DROPS IN RIGHT OVER OUR REGION. TEMPERATURES WILL BE COLDER  
WITH CHANCES FOR RAIN AND SNOW SHOWERS SUNDAY NIGHT INTO MONDAY.  
 
 
   
AVIATION /18Z MONDAY THROUGH SATURDAY/  
 
MVFR, OVERCAST CONDITIONS CONTINUE ACROSS THE AIRSPACE THIS  
AFTERNOON AND WILL REMAIN RELATIVELY STEADY STATE THROUGH MUCH  
OF THE TAF PERIOD. WINDS WILL START WEST TO NORTHWEST AND VEER  
THROUGH THE PERIOD TO THE NORTH AND NORTHEAST BEHIND THE COLD  
FRONT AND WITH ADVANCING HIGH PRESSURE FROM THE NORTH. THERE  
COULD BE SOME INTERMITTENT GUSTS TO 25 KT THIS AFTERNOON AND  
EARLY EVENING WITH SOME BETTER MIXING RIGHT BEHIND THE COLD  
FRONT. HIGH PRESSURE ADVANCING FROM THE NORTH WILL BRING DRIER  
AIR INTO THE REGION AND SCOUR OUT THE MVFR CEILINGS AND THE  
TREND WILL BE TO VFR LATE IN THE TAF PERIOD. MVFR COULD EXIT  
KTOL OVERNIGHT, GIVEN FAVORABLE, DRY FLOW ACROSS LOWER  
MICHIGAN.  
 
OUTLOOK...NON-VFR EXPECTED IN MULTIPLE WAVES OF SHOWERS  
WEDNESDAY THROUGH SATURDAY. ANOTHER ROUND OF THUNDERSTORMS IS  
POSSIBLE ON WEDNESDAY NIGHT.  
 
 
   
MARINE  
 
POST FRONTAL WEST TO NORTHWESTERLY WINDS 10 TO 20 KNOTS ARE EXPECTED

EASTERN NEARSHORE WATERS THIS MORNING AND ENDING LATER THIS  
AFTERNOON. HIGH PRESSURE BUILDING DOWN FROM ONTARIO AND QUEBEC WILL  
KEEP NORTHERLY WINDS 10 TO 15 KNOTS MONDAY NIGHT THROUGH TUESDAY.  
WINDS WILL SHIFT FROM THE EAST BY TUESDAY EVENING AND INCREASE 15 T0  
TO 20 KNOTS TUESDAY NIGHT INTO WEDNESDAY MORNING. ANOTHER ROUND OF  
SMALL CRAFT ADVISORIES WILL BE LIKELY LATE TUESDAY NIGHT INTO
