Joe's Look Ahead

Day Planner

Enjoy Today

The calm before the next front will be the theme of today’s weather.

We’ll have seasonably cool conditions with a light northwesterly breeze and highs in the upper 50’s to lower 60’s. Enjoy the sunshine and fall foliage today.  We will be past peak this weekend due to a developing snow storm. That’s right, a substantial blast of winter-like weather arrives late Friday, and frightening enough, the bone-chilling COLD air lingers into the weekend.

A reinforcing shot of MUCH colder conditions arrives Friday afternoon as a cold front pushes the coldest air of the season into our neck of the woods. Scattered showers will arrive on the hills of the frontal passage. Unfortuantely, the timing of the rain appears to impact area trick-or-treaters so the kiddos may need an umbrella while they head around the neighborhood.

A powerful upper-level low will dive into the region Friday night.  Bitterly cold air will wrap into the storm system changing rain over to snow area wide.  First, of course, in the mountains Friday evening, then into the valleys during the wee early morning hours on Saturday.

Significant snowfall now appears to be likely above 3,000′. If you have travel plans up I-81, across I-26 (Sam’s Gap) or I-40 allow yourself extra time to your destination.  Light accumulation still seems a good bet for the Tri-Cities on grassy surfaces.  This will be an upslope snow event, so expect the western facing slopes to pick-up the heaviest amounts.  Along the spine of the Smokies, aka Mt. LeConte (elevation over 6,000′) could have over a foot before all is said and done Saturday night.

Not only will snow be an issue in the mountains, strong northwest winds could gust over 50 miles per hour early Saturday. This would make the wind chill factors feel like the teens! Keep an ear outdoors, the dynamics of this phasing out could create a few claps of thundersnow Halloween night into Saturday morning.  -WOW!

It will be short and sweet, scratch that, I mean bitterly cold.

However, sunshine returns in full force helping to melt the snow off the mountains. Highs next week will rebound nicely into the middle 60’s Monday and Tuesday.

Reminder – We will catch an extra hour of Z’s Saturday night. Set your clocks BACK one hour, better known as ‘fall back’. Good news for those forecasters, like me, who need an extra hour to recover from the extra hour(s) spent in the weather office this week. Bad news as sunset will arrive at 5:31pm.  -Takes a lot of readjusting to get used to the sun setting so early.

We’ll bring you the latest on the developing Halloween storm tonight at 6pm and 11pm.
