Good Friday Morning. The full weather discussion will be updated later today. This focuses on the potential for a high impact icing event on Sunday Morning.
Saturday Night high pressure will ridge down the Eastern slope of the Blue Ridge. At the same time low pressure develops in the ARKLATX Region and moves Northeast. High pressure will move East out into the Atlantic and that is the key that saves us from a destructive ice event. By Noontime Sunday the wedge should breakdown and allow temperatures to jump into the upper 30's to around 40 degrees. So here is what to expect right now.
So how should you prepare? Right now this doesn't look to be an event that would keep you from traveling all day. The first half of the day will certainly be tricky. If the wedge holds on longer than anticipated then ice totals could go up. It takes approximately .25 inch of ice to start failing trees and powerlines. We have a lot of data to go through today and we will work on nailing down this forecast. It wouldn't be a bad idea to have a few non-perishable food items in case you lose power. The loss of power would be isolated at this point though, if any. We will continue to watch this.
