AWIS Weather Advisory 3/18/2021: The Coming Days Entail Storm, Rain and a Chance of Frost
Dear all,
Sever storms tonight will be followed by rain and colder temperatures this weekend. This puts growers into a rough spot, where row-covers need to be off the plants and secured, and probably be put back on for the night of Friday to Saturday.AWIS General Weather Discussion
Strong to severe storms were ongoing this morning across Georgia and points Northward into Virginia. These should push offshore by this evening. Rain was more steady North of there in the colder air, and that may linger through Friday.Rain totals from this system will be mostly under 1 inch Southern
areas to locally 1-2 inches Northern areas. However, colder high pressure builds in behind that for this weekend.
Thus the freeze threat this weekend will be highest from inland
areas of VA, Northward through MD and DE, where some areas may
see minimums in the mid 20s ranges. Dew points are low enough for areas further South to be of some concern. At the moment it looks like most areas should hold close to 30 and above given some wind and clouds.
Frost Possibility in Several Areas Across the East Coast Over the Weekend
If you haven't already, please take your row-covers and secure them in a save space. There will be more severe wind in Eastern North Carolina later today. As discussed above, temperatures will drop over the weekend (Figure 1). While I don't think there will be a severe risk for frost in Eastern North Carolina, growers in areas in the North Carolina piedmont, in VA and North need to be concerned and use row-covers to protect flowers.
