11/11 – Brittany’s “Incoming Cold Front” Friday Evening Forecast

Main forecast concern in the short term will be temperatures and winds with the greatest forecast question being morning lows Sunday and Monday morning. Remnants of Nicole continue to lift to the north and will be all but absorbed by the L/W trough which will dominate the eastern CONUS. As the trough axis moves across the MS Valley it will help to drive that cold front through during the morning hours. Skies should start to clear out by afternoon or early evening while surface winds should decouple right after midnight. Once the surface winds back down, temps should be able to drop quickly but radiational cooling will not be optimal. There will still be rather strong winds around h925 (2500-3k ft) so even if the surface winds are able to completely decouple there will still be some mixing in the boundary layer and that should keep temperatures from reaching their potential. Obviously the typical cold locations especially in the Pearl River and Pascagoula River basins cold air drainage could still allow these spots to be right around freezing.
