When will the rain stop and the warmth arrive? It's the question I've been hit with the most this Spring. This April has been one for the books. Through Wednesday (April 25th), the mean temperature for the month was 8.6º below normal, an impressive number. In southern Illinois, we've averaged four 80º days in April over the last decade, this year, we'll have zero. Over the same span, we've averaged less than one day with afternoon temperatures below 50º, this year has featured seven.
The pattern of cool weather holds through the weekend. With an unseasonably strong shot of cold air, patchy frost is a possibility on Sunday morning. Winds will be the key, but with high pressure nearby, I won't be surprised to see winds relax enough for temperatures to drop back into the mid to upper 30s with some frost development.

Beyond, the weekend, a pattern shift is in store finally. This time, it appears the pattern will hold for more than just a couple of days. I've been telling my farming friends eager to get corn in the ground, to be patient. There will be a good opportunity with dry weather expected through May 1st, but then the pattern turns VERY wet.
With high pressure positioned over the Southeast and the jetstream streaking across the Plains, it's often a great funnel of moisture from the Gulf of Mexico right into the Mid-Mississippi and Lower Ohio Valley. Heavy rain is a possibility later next week to kick off the month of May.
