As for rainfall, after another strong weather system the middle of this week with rain, weather systems are forecast to weaken for much of the middle of the month. This will reduce the wet pattern we saw in March into early April to more normal rainfall patterns.
Though mid-April, rainfall will average 1-2 inches across Ohio (see image). This is actually about normal to slightly below normal.
With La Nina gone, near normal last freeze dates are projected this spring with most freezes occuring by the end of April or very early May.
GROWING SEASON - May to early September
A warmer than normal late spring through summer and early fall is forecast. However, there is no indication of any significant number of maximum temperatures above 95 which is good news. Rainfall is officially forecast near or slightly above normal. However, with the rapid transition toward an El Nino that could cause a quick switch to drier than normal conditions in the eastern corn and soybean belt from June or July and on. We need to monitor this risk. If we remain in neutral conditions then any dry pattern would be off the table due to adequate soil moisture conditions. But if El Nino develops, things could change this summer quickly.
