Area Forecast Discussion National Weather Service Cleveland OH 759 PM EDT Sun Mar 8 2026
WHAT HAS CHANGED
Wind gusts have increased slightly with both systems on Wednesday and Friday. Otherwise, the forecast remains on track.
KEY MESSAGES
1) Breezy conditions, periods of moderate to heavy rain and perhaps a few stronger thunderstorms are possible Tuesday night into Wednesday. Rain will briefly transition over to snow Wednesday night into Thursday.
2) A clipper system will move east through the Upper Great Lakes on Friday which could bring a rain/snow mix to the local area. Confidence is increasing for gusty winds, particularly along and west of the I-71 corridor.
DISCUSSION
KEY MESSAGE 1...
A digging upper-level trough will cause a deepening low pressure system to track east-northeast from the mid-Mississippi Valley Tuesday night across Indiana/Michigan Wednesday and then southern Ontario Wednesday night.
Convection with mid-level frontogenesis will first impact the region Tuesday night. Moderate MUCAPE should support some isolated thunderstorm potential, and perhaps even some small hail given moderate deep-layer shear. Within the warm sector, pre-frontal thunderstorms are expected during the day Wednesday.
A very strong wind field would support organized severe convection, though details are uncertain regarding severe weather impact locally, especially regarding morning showers and the system's ability to develop sufficient instability.
Confidence in thunderstorms and subsequent severe weather is more likely the farther south and east you go within our forecast area.
It's very likely most of the area gets at least an inch of rain, with current ensemble mean for around 1.25-1.5" Tuesday night through Wednesday evening. High-end localized amounts up to 2-2.5" could be possible. Localized nuisance is possible, though higher flooding impacts could materialize is the higher end amounts of 2.5"+ occurs.
KEY MESSAGE 2...
A clipper system is expected to move east through the Upper Great Lakes on Friday, which could bring a rain/snow mix to the local area with gusty winds. Although some uncertainty exists in the strength of the system, confidence continues to increase for wind gusts to reach at least 40 mph and perhaps near Advisory-level (~50 mph).
AVIATION /00Z Monday THROUGH Friday/
VFR will prevail through the TAF cycle as high pressure strengthens over the Appalachians and Mid Atlantic regions. Only pockets of high clouds are expected at times. The position of the high will lead to SW winds that will be gusty Monday afternoon when winds will gust to 20-25 knots at times.
Otherwise, the SW winds will average 5-10 knots tonight and will diminish to 5-10 knots again by sunset Monday evening.
Outlook...Non-VFR likely with showers and thunderstorms Tuesday night into Wednesday followed by rain and/or wet snow Wednesday night into Thursday.
MARINE
A high pressure ridge exits slowly SE'ward from the Lake Erie region through Monday night as a strong cold front approaches from the northwest. Winds trend S'erly to SW'erly around 10 to 20 knots. On Tuesday through Tuesday night, the front should stall in vicinity of the southwestern Great Lakes, southern ON, and the border of QC and New England as multiple lows of varying intensity move NE'ward along the front. Winds should vary between SW'erly and SE'erly over Lake Erie. Wind speeds around 5 to 15 knots on Tuesday should freshen to around 10 to 20 knots Tuesday night. Waves should be 3 feet or less in ice-free waters through Tuesday night.
The strong cold front should sweep SE'ward across Lake Erie on Wednesday through Wednesday night as a stronger low moves NE'ward from the southwestern Great Lakes to southern QC. The front's passage will cause S'erly to SW'erly winds around 15 to 25 knots to veer to NW'erly. On Thursday through Thursday night, NW'erly winds should back gradually to S'erly as a ridge crosses Lake Erie from west to east and is followed by the N'ward passage of a warm front. Wind speeds should average 15 to 25 knots. On Friday, a cold front should sweep E'ward across Lake Erie and cause S'erly winds primarily around 15 to 25 knots to veer to W'erly. Waves should be as large as 4 to 8 feet at times on Wednesday through Friday.

Max temperatures are forecast to approach records on Tuesday, March 10th. Here are the record high temperature at area climate sites for March 10th.
