Cold Air Invasion Later This Week

Another piece of cold air is poised to plow through here with plummeting temperatures and plentiful precipitation possible. However, a perplexing piece of the puzzle remains. Any wintry weather working its way from parts of the prairies and pastures of the Canadian provinces?

I've been looking at models, reading other professionals' blogs, digesting information from the National Weather Service offices, and consulting past analogs for the past few days about this upcoming shot of cold air coming our way.

I keep seeing a similar theme. Either the models and analogs are just waiting for more information to digest, or a consistent pattern is developing regarding how this system will unfold.

I don't foresee any wintry precipitation with the models I've been perusing (except in the usual higher elevations of east KY). That still has time to change. The NAM models will now be able to offer some hints. Also, as the storm system pushes closer, the other models should be able to figure this one out, probably by the end of the day or first thing tomorrow.

Although the NWS office here in Louisville continues to advertise high temperatures in the 50's after frontal passage, I still haven't been sold on that thought yet. I think we'll have a difficult time getting out of the 40's one day this week, possibly Thursday. By Friday or so, highs may struggle to reach 50 or 51.

Today, I'll be interested in other NWS offices' thoughts outside of Louisville and read their thoughts about the upcoming week.

In a later post, I'll share some of those with you. In the meantime, have a good one.
