Did you plant your Spring garden yet? If you did, chances are you’ll need to make a run for some cold weather survival supplies for those plants. Temperatures may be as much as 15ºF to 20ºF below average for April by Friday, Saturday and Sunday:

From our Forecast Discussion:

An unusually cold weekend on the way: Colder, drier air blows in Thursday setting up near-record cold for Friday and the weekend. Friday will be a chilly, breezy day with a high in the upper 50s and some sun, but temperatures plunge toward the low-30s (and even some upper-20s) by Saturday morning.

Saturday’s record low in Huntsville is 28ºF; Sunday’s is also 28ºF (both in 1914). Huntsville’s official reporting station probably won’t come close to those numbers, but the usual cold spots like Meridianville, Winchester, Russellville and Valley Head very well could be that cold both mornings. That means a widespread frost is likely; some of those usual areas could see two freezes this weekend.

The forecast for the next ten days looks to be around 5-6ºF below average. The normal range for a single day in April is about 8ºF from the 30-year average, so while we may not be setting records everywhere, this will be a cold snap you'll remember for a while!

If you have plans to head for the Great Smoky Mountains this weekend, you may even run into some accumulating snow in the higher elevations!

An inch or two up to a half-foot of snow may fall from the Tennessee-North Carolina border north through mountainous parts of Virginia and West Virginia through Saturday afternoon.
