The average temperature for April will be below normal. Precipitation will be above normal for the month.
The outlook for April is that it could be a lot like March. An upper level trough will persist north of the Great Lakes during the first part of April. The trough will pull colder air over Ohio and the temperature will be below normal during much of the first half of the month. The upper level flow could change in the middle of the month to a fast west to east flow across the U.S. That flow will carry a series of storms across the country. The temperature will warm ahead of each storm and cool after the storm passes. Overall, the average temperature is likely to be below normal for month. The storms will also pull moist air from the Gulf of Mexico toward Ohio. They will produce periodic rain and some storms could produce locally heavy rain. The chances for severe weather will increase later in the month.
