Weather Update

The weather pattern will trend closer to normal into early June. However, it still favors the risk of bursts of cool and damp weather in the eastern corn and soybean belt into summer as a results of this past winter and early spring. 
The weather pattern will be influenced by the colder than normal Great Lakes and Hudson Bay waters. These colder than normal waters will have some say in the shape of the weather patterns with a favoring of cooler northwest flow outbreaks of cool air.
Further, Lake Erie cool waters should help enhance rain chances in north central and northeast Ohio into early summer. Not good news there.
The outlook for the week of May 19 calls for a warmer start to the week with highs in the 70s to near 80 then a cooler finish in the 60s to near 70 for highs then back to normal by the Memorial Day weekend. Normal highs are in the 70s and normal lows are mostly 50s now. The best chances for rain will be later Tuesday into Wednesday with a cold front. Northeast Ohio may get more rain than most due to lake enhanced rainfall. Most places will see 0.25 to 0.75 inches of rain this week but locally higher totals in thunderstorms can be expected.
The outlook for the week of May 26 calls for near to slightly above normal temperatures with near normal rainfall.
As the risk of an El Nino forming this summer, crop yields tend to be more vulnerable in the eastern corn and soybean areas including Ohio.

It is updated daily and the run from Monday indicated not too far from normal rainfall for Ohio except above normal in the northeast near lake effect prone areas.
