Showers are forecast to end about 2:00 p.m. Monday. There was no rain in Sunday's forecast for Monday. If you want the technical excuse for this rain, warm advection ahead of an associated approaching surface cold front led to increased shower coverage, but dry air in the low-to-mid levels is preventing significant rain from hitting the ground. Next chance for rain is 1:00 a...
