Monday Weather Discussion

Good Afternoon!

Synopsis:  Current surface map http://www.hpc.ncep.noaa.gov/sfc/awc90f.gif shows a cold front has moved through East TN and is now pushing southeast into the Mountains.  Cooler and drier air will continue to work into our region behind this front with partial clearing this afternoon.  This front will return back north as a warm front tomorrow bringing more showers and milder temperatures later Tuesday.

This Week:  A very active weather pattern sets up for Tuesday through Thursday, with warmer air bringing in showers and thunderstorms Tuesday night into Wednesday ahead of a strong frontal boundary.  Some of the rainfall could be heavy at times, especially across Middle TN: Windy conditions are also anticipated ahead of and behind this cold front.  This same cold front will bring a brief shot of arctic air back into our region Thursday with temperatures falling around 30 degrees in about 3 hours time!  In addition to the rapid change and falling temperatures, rain is expected to change to snow Wednesday night into early Thursday morning as moisture hangs back behind the front http://weather.unisys.com/gfs/gfs.php?inv=0&plot=500p&region=us&t=3e.  At this time, around 1 inch of snow is possible from Knoxville north, with much heavier amounts > 4 inches well to our north up in Kentucky: We will continue to monitor and keep you updated.  The front moves through Thursday with clearing skies and much colder air remaining in place for Friday with morning lows in the middle teens and highs only in the middle to upper 30s.

The Weekend:  Good news!  Sunshine returns as does the drier weather this weekend!  Temperatures will be cooler-than-average but slowly warming with highs in the 40s Saturday and back into the lower 50s Sunday.  Morning lows will be cold in the 20s.

Enjoy the rest of your day!
