This is just a Saturday afternoon update on the winter wx situation for Sunday night and Monday morning. Not much has changed with the forecast reasoning today. Guidance continues to show precip moving in after midnight Sunday for the Cumberland Plateau, beginning as light snow and sleet, with very light accumulation possible. The light precip will transition to light freezing drizzle/rain and sleet for Monday morning. The greatest impact to the plateau will be to travel. Anyone with travel plans Sunday night or Monday morning should understand that travel may be hazardous at that time. It only takes a thin glaze to create hazardous roads. Be aware of black ice.
Some key points concerning our current thinking:
- The wintry mix should hold off until after midnight Sunday.
- The wintry mix is expected to be light.
- The greatest impact should be to travel. Even freezing drizzle can create a travel nightmare.
- All wintry precip should be plain rain by noon on Monday (if not earlier).
Stay tuned by following this blog and by following me on Facebook. I’ll be here all day Sunday to update you on any changes to the forecast. A winter weather advisory is expected to be issued by the National Weather Service for the Cumberland Plateau sometime Sunday. The advisory will go into affect for us after midnight Sunday.
Possible implications to this forecast include the arrival time of the precip and duration of the sub-freezing air. If precip arrives earlier than expected, or the sub-freezing temps hold on later into the day on Monday, ice amounts will have to be increased. Never the less, even the worst-case scenario still keeps us below ice storm criteria.
You all have a wonderful evening and stay warm! Lows tonight will dip to around 10 degrees.
Also, I almost forgot to mention that winds will pick up on Sunday and will make it feel much colder. Highs will climb into the 30s, but the wind will make it feel as cold or colder than today’s high of 25.
