Good Tuesday everyone and welcome to the frozen tundra of Kentucky. Our little taste of what life is like well to our north has a few more days before the action kicks back up by the weekend. We have a big winter storm that will take aim on the Ohio Valley, Great Lakes and northeast from Saturday through Monday. That will be followed by a major arctic outbreak.

In the short term… it’s more arctic cold temps and snow showers and squalls today. The greatest concentration of the snows will again be across eastern and southeastern Kentucky. It is this part of the state that should pick up more in the way of light accumulations. That said… any one area that gets under a stronger snow shower can pick up a quick coating to an inch. Radar will continue to show these bands right on through the evening hours…



The arctic air today means temps will be very close to what we had for Monday. Highs will generally run in the low 20s with a few spots hanging in the high teens. Western Kentucky will see upper 20s to low 30s. Factor in the winds and you our readings will feel at or below 0 at times… especially in the morning hours.

Wind Chill



Highs for Wednesday will continue to run in the 20s as our snow showers and flurries finally wind down. Lows the next few mornings will head into the low teens with a few of the cold spots hitting the high single digits.

A weak system now looks to pass to our north Friday with only a small chance for some early day flakes across the north. All eyes will then be on the weekend and what looks to be a major storm for much of the eastern half of the country.

There are a lot of options for the first part of the storm for Saturday. There is really only one option for Sunday into Monday and that option is for snow and bitterly cold temps.

Saturday looks to be the wild card in all this. One low will work toward the region from the southwest friday night through Saturday. As I see it…this storm can do one of three things…

 1.
It can strengthen all the way to the Great Lakes as another low cranks to our southeast.  2. It can work into the lower Ohio Valley before weakening out fairly quickly as the secondary low across the mid atlantic takes over. 3. It can sense the blocking in place and heads more west to east across Kentucky and Tennessee the REALLY cranking as it turns the corner up the east slopes of the Appalachian Mountains.

The overnight run of the GFS is trying to take the more southern route Option 3 with the storm…



The GFS Ensembles are taking Option 2…



There have been several other computer model runs taking Option 1 with a strong low all the way into the lakes. Any of the scenarios result in snow Sunday then snow squalls into Monday and Tuesday with bitterly cold temps.

I will have another update on the weekend storm coming later this afternoon so make sure to check back. Have a great Tuesday and take care.
