A strong area of low pressure centered over southern Missouri this morning, will move northeastward to western Ohio tonight, then to Lake Erie on Wednesday.
Deep moisture will surge northward across the area today. At the same time, milder air will also overspread the region from the south. Rain will break out from south to north today. A few areas could see some mixed precipitation at the onset but little, if any, ice accumulation is expected.
The rain could be heavy at times this afternoon. Highs today will be in the upper 30s to near 40 degrees.
Rain will continue into tonight as the system passes just to our northwest. Colder air will gradually be wrapped into the system tonight. Surface temperatures will fall to the low 30s and this will support a mix of rain and snow after midnight. Some locations could even change to all snow.
On Wednesday, rain and snow will continue. Highs will reach the mid to upper 30s.
Wednesday night and Thursday, the storm will move slowly eastward into New York state. Moisture will continue to wrap around the system across our area. Temperatures will cool sufficiently for a change to all snow across the entire area Wednesday night, with periods of snow continuing through Thursday. Some light accumulations are possible. Lows Wednesday night will be in the upper 20s with highs on Thursday in the low 30s.
Snow showers will continue through Friday before conditions finally begin to improve. Temperatures will continue to gradually cool with highs on Friday not making it out of the upper 20s.
