As we close out the work week in the 60s, a whole different world will find us tomorrow. Satellite depicts sunshine and a few clouds across East Tennessee, while to our west a strong cold front is approaching. As it does so, rain showers will turn to snow overnight. Because of this, a Winter Storm Warning has been issued for the greater viewing area. All but the far northeast is under a warning, while these areas are under a winter weather advisory. Looking at this transition, most will see the changeover after midnight. Timing...... Midnight - 2 am for the Plateau 2 am - 4 am for the Valley 4 am - 6 am Foothills/Smokies Given the warm surface temperatures we will have because of this afternoon, this will likely eat into snow totals initially. Given the high snowfall rates associated though, this will help overcome the warmer conditions and lead to accumulations. With that said, our best opportunities for accumulating snow will be on grassy and elevated surfaces. Roadways will be much slower to build snowfall (good news), but if they do so, it could lead to a slushy mess and potential icing by Sunday morning. By the end of the weekend, sunshine returns as well as warmer temperatures and this trend looks to continue into the new work week as well. In addition to the change over, winds will be breezy. Not only will this make for colder feel-like temps, but will also create hazardous visibility conditions. Here is a depiction of some of the wind gusts we could see overnight, ranging from 25 and 35 mph. Lastly, the probability for 4 inches or more is low across the Valley 10-40% but not entirely ruled out. The best opportunity will be across the Plateau and into Eastern Kentucky. With all of this said, accumulations have been bumped up a bit. Given the better snowfall rates associated with this front, valley locations can anticipate between 2 and 3 inches, with the southern valley between 1 and 3 inches. The plateau will have the best opportunity, with 3-6+ inches possible. All will face a driving danger, as slick roads and reduced visibilities (overnight) will be present.

A building warm front will advect in warmer air today and tomorrow, with highs to end the work week Friday in the mid to upper 60s. Keep in mind these temperatures and the roll they will play in any snow accumulations (more info below). Looking at the past 24 hours, temperatures are around 10 degrees warmer today and that trend will continue into Friday as well. Things quickly change by Friday night, as a very strong cold front will surge through the area. This will allow for the change over to snow and provide accumulations across the area. Given the very warm surface temperatures Friday afternoon, this will likely eat into accumulations. A slushy mess is likely on the lowest layer, which could pose additional issues Saturday night into Sunday with lows dipping into the single digits and teens. High pressure fills in Sunday, warming temperature back up to end the weekend and into the new work week. Here is our rough accumulation map for Friday night into Saturday. Those living in the Plateau, especially Northern Plateau, could see locally higher amounts up to 6". For the Central Valley, generally between 1-2" is possible, with lesser odds the further south you go. If snow can hold on through Saturday, we could see an icy layer below the snow (given the expected warm surface temps initially) Sunday morning. Changes will continue to be apart of this forecast, but generally expectations are for what is mentioned above. Partly cloudy skies continue this afternoon, with sunshine to start us off Friday as well. Increased cloud cover will then follow for the later half of the day, with rain showers by the late evening then snow thereafter. Have a way to receive alerts, as I fully expect a winter weather advisory to go out for the greater part of the area. Pre-recorded for 5pm show
Showers have vacated the area, leaving only cloud cover it their wake. As we work through the day, some will see a bit of sunshine, but better opportunities will be in store for Thursday. Highs today will be seasonable in the low to mid 50s, warming to the low 60s by this time tomorrow. Turning our focus to this weekend, confidence continues to increase that most will see some snowfall Friday night into Saturday. A very stout cold front will make its way through, providing the chance for light to moderate accumulations across the area. Higher snowfall rates will also accompany this, helping to overcome the warm surface temperatures that will be in place. Following, cold temps will be around Saturday (mid 30s) before much warmer and drier air returns Sunday and Monday. Taking it one step further, this is highlighting the most likely outcome. As you can see, valley locations can see up to 2 inches of snow, with the Plateau and higher elevations (north) between that 3-6" range. The southern valley will have the "shorter end of the stick" with accumulations between a dusting to 1 inch. Changes will be likely with this, but prepare yourself now for snowfall potential. Again, timing will come Friday night into Saturday morning as rain changes over to snow behind a quick moving and strong cold front. For now, enjoy the decreasing cloud cover and warming temperatures. Highs will return to the 60s tomorrow, with partly cloudy skies above. A late time season winter system will then take aim late Friday and into the early weekend. More details can be found below as well! Pre-recorded for 5pm show
Good afternoon! Cloud cover has slowly diminished so far today but that won't last too much longer. Unfortunately for you sun lovers, this will be short lived. Our next system is quickly on the way and will arrive this evening and into the overnight hours. Though severe potential is off the table, we could see some localized flooding issues. Heavy rainfall will equate to good sleeping weather tonight, but also rainfall amounts between 1 and 2 inches. Breaking down our next system, it will clip the eastern half of the state tonight, working out by mid morning tomorrow. By the afternoon, gradually decreasing clouds will occur, with dry conditions expected through Thursday. Our third system then takes aim Friday and into the weekend. This one is worth keeping a close eye on as rain could transition over to snow. Guidance has been trending fairly consistently that there will be some snowfall across the area. We will hold from providing any accumulations for now, but the best opportunities will certainly be in the higher elevations. All will have a reasonable shot for at least some measurable snow Saturday morning if the current trends hold. We will have more in the days to come. Looking briefly at one of the runs, the top 3 extended models are hinting at this transition taking place. A stout cold front will slide west, bringing rain showers initially Friday evening, before a sharp transition over to mix and then snow late Friday night. As highlighted, guidance has been hinting at this for a couple of days, but we will closely eye the trends as timing, temperatures, intensity will be three big ingredients in making this come together. For now, get those umbrellas ready, as all will see showers tonight and lingering activity into the morning hours tomorrow. Highs will be warming as well through the next couple of days, in the upper 50s tomorrow and upper 60s by Friday. Pre-recorded for 5pm show
Good afternoon! A line of showers and a few embedded thunderstorms are working through now. These have been fairly week, and as such, the slight risk has been removed from the area. With that said, gusty winds and heavy rains will still be possible as this passes. Cooler air will then fill in tonight. Looking below, you can see the very cold air already filling in across locations to the west. This will continue trending east as the front pulls out of the area this evening. Highs will fall 15-20 degrees, with most in the mid and upper 50s for Tuesday. We quickly warm back up, with highs returning to the 60s Thursday and Friday. This week will be rather active with several rounds of rainfall expected. Once this one works out tonight, another will arrive from the south. Timing comes Tuesday evening/night and into the first half of Wednesday. We dry back out Thursday, with another strong cold front bringing showers and storm potential Friday and into the weekend. This one could even allow for a transition to mixed precipitation. Given the timing in this, will hold from going into much detail, but do expect cold temperatures once again to arrive for the weekend. That will do it for today....other than the heavy rainfall the next couple of hours, we should dry back out for the greater portion of Tuesday. Highs will be cooler so don't forget to throw on that jacket! Pre-recorded for 5pm show
With the passage of a cold front, temperatures are a bit cooler across the region but this is mainly off to our north. That same front that brought cooler air will now build north in the form of a warm front today, tomorrow, and Sunday. Potentially record setting highs and maximum lows are on tap. Records for Knoxville break down as follows: Current Record Highs 5th: 78 (1910) 6th: 79 (1983) 7th: 80 (1983) Our best chance for a record will be Saturday or Sunday. Looking at the latest drought map, it is not a surprise we are right on par with normals. Given all the heavy rainfall the past two weeks, this was anticipated. With more rainfall on the way and guidance suggesting a wet month ahead, little to no changes are likely ahead. As mentioned, a warm boundary will build north. As it does so, increasing temperatures and moisture will arrive across East Tennessee. This will lead to cloud development and eventually showers. Besides a few hit or miss isolated showers late Saturday and at times Sunday, most will be on the dry side until Monday. A sweeping cold front will pull through, bringing widespread showers and a few isolated thunderstorms. Cooler air will then fill in Tuesday and Wednesday. Other than a few stray isolated showers, breezy conditions Saturday (gusts up to 25 mph), and increasing cloud cover, it should be a very warm and pleasant weekend. Have a good one and break out those rain jackets for showers and storms on Monday. Pre-recorded for 5pm show
