Updating The Light Snowfall Chance

Good evening, folks. Another light snow maker blows into the region tonight, likely putting down some light accumulations just in time for the morning commute. Beyond that, things continue to remain active with another snow maker possibly showing up later in the week.

The one coming late tonight and early Tuesday won’t be very impressive on radar, then you will see light stuff developing right on top of central and eastern parts of the state. Northwesterly wind will then touch off some snow showers and snow squalls across the east. The future radar from the HI RES NAM continues to illustrate this very well…

This is another light event, with coatings to 1″ possible for some. Here’s the First Call For Snowfall…

Slick travel is a possibility early Tuesday, especially across the east and southeast. I do not expect this to be a repeat of what happened Saturday. Your best chance for a snow day or some delays will be across the east.

Gusty northwesterly winds will kick in, causing our temps to drop all day through the 20s.

Another system then shows up Wednesday night, but the track on that is all over the place. It may try to bring a band of light snow across the northern half of the state.

The more interesting system comes Thursday night into Friday. Another northern branch system digs in across the lower Ohio Valley, spawning another low to our southeast. That system then tries to ride the east coast. That scenario would bring more light snow across our entire region.

Here’s the new GFS…

Can we get that east coast system to actually trend farther west in the coming days? We shall see, but it’s an interesting look.

After that blows through, temps come up by Saturday, but another system quickly moves in by Sunday. This one may be a mixed bag of wintry weather for us.

I will update again later tonight. Have a good one and take care.

Monday Midday Update

Good afternoon, my little snow lovers. Our late night light snow maker continues to work toward the region, with the system later in the week starting to get a little more of my attention.  I’m not sure if that’s good or bad. 🙂

A clipper works into the Great Lakes and Ohio Valley tonight and Tuesday. This will bring a burst of light snow along and behind the front, with snow showers and a few squalls kicking in behind it into Tuesday.

The HI RES NAM continues to pick up on this well…

Light accumulations of snow are possible across central and eastern Kentucky starting very late tonight. Snowfall should range from a coating to 1″, with the potential for some higher amounts in the eastern mountains. While this is a light snowfall, we’ve seen what these kinds of deals can do to untreated roads. Slick travel is possible, especially across the east.

Temps drop from the low 30s in the morning, to the low and mid 20s by late afternoon. Gusty winds will make it feel much colder.

Actual lows can flirt with 10 degrees in some areas by Wednesday morning.

The next system is a clipper zipping across the Ohio Valley Wednesday night…

That brings another piece of cold air behind it for Thursday as we wait on the next system showing up on Friday. A few days ago, I talked abut how the system was trying to dig in, courtesy of a negatively tilted trough. That’s showing up a little stronger today…

That’s more of a “leaning” trough, but it tries to pop a system just to our southeast and ride it up the east coast, bringing snow to our region…

Could we get the infamous northwest trend to show up on that system? Maybe so, but let’s see if it’s real first.

The Canadian Model has a similar, albeit weaker, look to the GFS…

With a deeper trough showing up later this week, that forces the weekend system farther south and colder. Here’s the GFS for Sunday…

I will update things later this evening. Make it a good one and take care.

Arctic Front Brings Light Snow On Tuesday

Good Monday, folks. An arctic cold front is ready to push in here later tonight, bringing another round of light snow and snow showers to the region. In addition to the flakes, temps are going to crash in a hurry, with frigid wind chills taking shape.

Today’s a decent day with highs in the 40s and some clouds increasing. The front blasts in here tonight with light snow and snow showers breaking out behind it. That happens on a strong northwesterly wind flow. The HI-RES NAM did well with our Saturday evening and seems to have a solid handle on the Tuesday flakes…

Notice that long snow streamer stretching from Lake Michigan into the Appalachian mountains. It will be interesting to watch where that sets up on Tuesday.

Light accumulations are likely across central and eastern Kentucky, with some local 1″ amounts possible where snow squalls set up. We won’t know where those show up until we are seeing them on radar.

Can we get a snow day for some districts tomorrow? Yes, especially across the east and southeast.

Temps and winds are the other big story. The thermometer readings crash all day long. Check out the forecast numbers on the NAM…

Wind gusts of 30mph may give us late afternoon wind chills in the single digits at times…

With clearing skies and arctic dewpoints nearing 0, lows by Wednesday morning can drop to near 10 degrees in some areas.

Another clipper moves across the Ohio Valley late Wednesday and may bring some flakes in here. The one coming behind that one later Thursday and Friday is trying to dig a little more on the GFS…

Temps recover some over the weekend, but the models are shortening the lifespan of that. The GFS has this system showing up by Sunday…

Another shot of cold follows that up to kick off the week leading up to Christmas. I’ve been mentioning how the southern branch of the jet stream is showing signs of life and you see that with the map above. I’ve also been talking about a cold look on the Ensembles leading up to Christmas. The GFS is seeing both of these in the run up to the big day. Here’s the latest GFS run for the end of next week into the start of Christmas weekend…

And for the big day…

Don’t worry, we only have 52 more runs of the GFS to go through before Christmas. What could go wrong? 😉

I will have updates later today, so check back. Make it a great Monday and take care.
