Latest Info – Winter Storm, February 20-21, 2015

The conference call with the National Weather Service has concluded.  Here are the highlights:

– Frozen precip accumulations expected across the area, beginning Friday into early Saturday morning.

– Could see some significant rains into Sunday

– Light snow will begin to develop before daybreak across W TN and will spread eastward through the morning.

– The snow will begin impacting the I-65 corridor sometime in the morning and the Plateau later on in the afternoon.

– Most areas will see snow for several hours, then a transition to some sleet, then a transition to freezing rain.

– We’re expecting 1-2″ of sleet/snow.

– The southwest counties will see a transition to ZR (freezing rain) early Friday evening.

– Friday night, warm air advection (WAA) screams in which is fueling the precip transition(s).

– The southwestern counties should be all rain by late Friday night.

– Areas north of I-40 and east of I-65 will stand the greatest shot at “significant” ZR accumulations.

– Winds will begin to pick up in earnest, especially across the higher elevations, with wind gusts 30-40mph not out of the question.  This will enhance the possibility of power outages.’

– By Saturday, everyone west of the Plateau should be all rain.  The Plateau will make the final transition to an all-rain event by late morning Saturday.

– Forecast highs Saturday will be in the 40s, which will serve to help thaw the frozen wasteland.  We’re expecting 1-2″ of rain by Sunday, so there could be some minor flooding.

– Another front comes in Monday morning changing whatever leftover liquid precip there is to frozen.  Not expecting that to be a big deal.

Take the time now to prepare for this impactful event.  Power outages are possible, but should be short-lived as the ZR changes to RN.  Keep tuned in to multiple reliable weather sources, as conditions could rapidly change.
