Heavy rain and a few storms are impacting the Mid-Atlantic & Coastal New England Friday with some risk for flash flooding. A cold airmass behind that system has pushed in the MS River Valley which will drop temperatures below freezing for the Central Corn Belt Sat AM. A frost event is possible Sun AM for much of the Mid-South. Extended warmth expected through next week, across the Midwest, will likely delay soil temps persistenting below 50°F. NH3 applications may be delayed until late November until temps return to normal for many areas while weighing low moisture concerns
