A big warm-up comes with rain

Good Tuesday to one and all. We have a quiet couple of days ahead of us, and then things will get a little crazy. A major blast of mild air will invade the Bluegrass State later this week, but it will come with a price. We have a lot of rain on the way later this week and the coming weekend. Then the cold air takes over.

The short-term forecast is for partly sunny skies today into Wednesday, with temps on the rise. We will be near 50 today and then into the low 50s by Wednesday. This is when a storm system from the southwest throws some clouds our way. That system will then bring an increase in showers and thunderstorms from Thursday into early Friday.

You can see that very well on the simulated NAM radar:

Locally heavy rain will be possible with this dynamic setup. Thursday’s temps will rise toward the low 60s. Those 60s will kick into high gear Friday and Saturday as that storm pulls away and the next one works in from the west.

We have a shot at record highs across portions of the state on Saturday.

Low pressure will be rolling into the Great Lakes this weekend, and it will drag a cold front eastward across Kentucky. That front will be a slow mover and will have a major temperature gradient to work with. Check out the Saturday afternoon temps from the GFS:

If we can get some sun, 70 is within reach on Saturday around here. But you can see the buildup of cold air coming in behind that front. The cold will bleed in here late in the weekend into early next week. The slow movement of the cold might set the stage for another round of heavy rain and thunderstorms.

Once the front finally clears the state to the east, a harsh period of winter will get started. This is likely to be a 4- to 6-week run of cold and snow chances for our part of the world.

Make it a great Tuesday and take care.
