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!

** In this day and time with all of the advances in technology and weather apps, there is a lot of misinformation floating around on social media.  My goal is to try to give you an accurate, responsible forecast that you can trust.  And one that will bring clarity in a social world full of weather information.

Monday Weather Discussion

Good Afternoon!

Synopsis:  Current surface map http://www.hpc.ncep.noaa.gov/sfc/awc90f.gif shows a cold front in the Central Plains moving slowly east.  Summer-like heat and humidity will be experienced east of this front, including here in Tennessee, for the next several days until the front passes through on Thursday.  This front will produce heavier thundershowers  along its path followed by much cooler air as it moves slowly east this week.

This Week:  Summer-like heat will continue Monday through Wednesday with highs in the middle to upper 80s each day.  The aforementioned slow-moving cold front will combine with an upper-level trough digging through http://weather.unisys.com/gfs/gfs.php?inv=0&plot=500p&region=us&t=3e to produce widespread showers and t-storms late Wednesday into Thursday.  Strong to severe storms may develop in Middle TN during this time as well.  The front will move through Thursday with clearing skies and much cooler air flowing in by Friday.

The Weekend:  Temperatures will continue to be cooler-than-average through the weekend with highs in the 60s and lows in the 40s expected http://www.cpc.ncep.noaa.gov/products/predictions/610day/610temp.new.gif.  A quick-moving disturbance may bring a few passing light showers on Saturday.  Otherwise partly cloudy and cool conditions are expected this weekend.

Enjoy the rest of your day!

Wednesday Weather Discussion

Good Afternoon!

Short-Term:  High pressure will continue to build into East Tennessee the rest of the week with clear skies continuing but also chilly temperatures into Friday.  At least we’ll have sunshine the next two days to end the week.  The other weather story will be the very cold temperatures tonight and tomorrow night with lows in the upper teens expected … bundle up!

The Weekend:  After a chance for a brief wintry mix early Saturday morning, expect a nice warming trend this weekend with highs in the middle 50s on Saturday, then warming into the middle 60s under a partly cloudy sky Sunday.  Rain is expected to return late Sunday night.

Next Week:  Rain showers are likely on Monday along with cooler temperatures in the 50s.  We then will see even colder temps sliding in Tuesday and Wednesday, with highs in the upper 30s to lower 40s.

Enjoy the rest of your night!

Tuesday Weather Discussion:

Good Afternoon!  

One weak disturbance continues to move away to our East, allowing for partial clearing with mixed sunshine and high clouds this afternoon.  Latest visible satellite shows some high clouds still streaming our way http://www.aviationweather.gov/adds/satellite/displaysat?region=MGM&isingle=single&itype=vis.  Temps remain on the cool side near 50 for the rest of today.

 

Tonight/Wednesday:  

 

Two other impulses move our way by early Wednesday morning, one to our North and one just to our South.  Latest guidance is indicating the southern disturbance could pull just enough moisture up from the south (from Alabama and Georgia) into southern parts of Tennessee.  With cold air in place overnight, parts of the Southern Valley could see some light snow accumulations early Wednesday morning.  This would include the counties of Hamilton, Bradley, S. McMinn, S. Monroe and Polk, then eastward into NC.  Further north, the rest of East TN will likely experience just some flurries Wednesday morning, then clearing by afternoon and much colder.  The northern disturbance will likely only affect SE Kentucky and SW Virginia with a light snowfall accumulation of an inch or two possible in those regions.  

 

In summary: Slick roadways are possible early Wednesday across extreme southern sections of East TN, as well as across SE KY and SW VA and possible Upper East TN border counties.  Highs Wednesday will only be in the middle to upper 30s, so dress warmly tomorrow!!
