Thursday March 18 2021

The severe weather outlook for today from the NOAA Storm Prediction Center highlights the Carolinas. We will have a wet day starting with heavy rain, and perhaps some thunder later this afternoon and evening. 

Severe Storm Outlook

  • The Enhanced to Moderate risk regions are where it is most likely to get large hail, damaging winds, and possible tornadoes.
  • Marginal Risk includes southern Maryland and Delmarva. It is most likely that just strong storms with thunder and gusty winds pass through. But there may be one cell with severe limits reached.
  • Most of our region will get steady, heavy rain. Some cells later today could produce thunder.

Morning Surface Weather

The rain has moved in and temperatures are in the mid 40s. This will be a chilly rain through early afternoon. Then scattered showers and some storms mid afternoon and tonight.

The Primary Low Pressure will be passing through tonight, so we have a lot to pass through our region.  Total rain expected is between 1 to 2 inches by Friday.
