Middle Tennessee Basin

Introduction
The upcoming week is going to bring some very extreme winter weather to portions of Middle Tennessee. Forecasting this upcoming week has been more than a challenge. This forecast continues to change by the hour, and I am afraid this event has the potential to continue to surprise until its over. For now, will go with my best gut feeling as far as precipitation types and accumulations. Will also review what Watches/Warnings have been issued by the national weather service.
Forecast Discussion
Remaining cold arctic air associated with high pressure to the north is going to become embattled with some warmer, more moist air aloft flowing up from the gulf of mexico. This is going to create periods of freezing rain and sleet for portions of northern and northwestern middle tennessee. Central and southern middle tennessee should stay mostly in the rain category, but we will have to monitor surface temperatures just in case models are underdoing cold shallow air. The farther northwest in middle tennessee that you travel, the worst the conditions will be. A damaging ice storm is set to cripple portions of missouri, southern kentucky, northern arkansas, and northwestern tennessee. Loss of power is something that may become an issue on into the day tuesday. Residents in the above area's need to finish preparations today for a damaging and possibly lengthy ice storm this week.
