February 24: Rain To Snow, Warmer Weekend, Daily Links

WEATHER

Big changes ongoing today, as the major storm system that brought last night’s rain continues to move off to our northeast.  Once again, the best chance of severe thunderstorms will be hundreds of miles away from us, and once again the best chance of significant snow will stay to our north and northwest:
BIG PICTURE
There will be plenty of moisture wrapping around that “L”, which means off-and-on showers are likely throughout the day.  There will be plenty of cold air wrapping around that “L” as well, which means we’ll see falling temperatures all day, and some snowflakes mixed with the raindrops by this afternoon.

Here’s Futurecast’s version of the radar simulation and temperatures, side-by-side through today and into early evening.
RPM 11A WED RPM 1P WED RPM 3P WED RPM 5P WED
Notice that while the radar simulations shows more and more snow, the temperatures will remain well above freezing — so while you’ll see some flakes in the air, those flakes will melt as they fall onto the relatively warm (and wet) ground.  WET roads, not ICY roads, will slow down the afternoon/evening commute.

You could pick up some slush on lawns and rooftops in southern Kentucky and northeastern Middle Tennessee by early evening, but the chances of accumulating snow will take shape late this evening, overnight, and Thursday morning, when temperatures will drop to near freezing:
RPM 8P WED RPM 11P WED RPM 2A THU RPM 5A THU RPM 8A THU RPM 11A THU
How much?  Futurecast’s estimate:
PAUL RPM 4KM - SNOW ACCUM
And my estimate, complete with the boom/bust possibilities:
PAUL SNOWFALL 2
That’s enough along the Cumberland Plateau for the National Weather Service to hoist a Winter Weather Advisory from midnight tonight through noon on Thursday:
PAUL WATCH

Some lingering mixed showers will possible again by Thursday afternoon, mostly northeast of Nashville again…after that, things should finally quiet down completely by late Thursday evening:
RPM 3P THU RPM 6P THU RPM 9P THU

Chilly air will prevail through Friday, even as skies clear out, then we’ll warm up nicely over the weekend.  A weak little cold front will give us a slight chance of showers Sunday evening and overnight, but it doesn’t look impressive — in fact, temperatures won’t change much at all Monday and Tuesday, as we finish off February and head into March.
7 Day PM
