It was close to 80 here today in Bloomington IL, My strawberries have blooms on about half the plants.... I would guess about 2-3 weeks ahead of what normal is supposed to be. Broccoli, Cabbage, Lettuce, Onions, Spinach and Chard are growing well... I had a few extra tomatoes and put a few out early to see how they would do.
The 10 day forecast is for highs in the mid 60's and lows mostly in the 40's. Cooler, but probably a bit warmer than normal.
