From 60s to snowflakes

Good Sunday, everyone. We have some big weather changes blowing in over the next 24 hours. A mild Sunday will turn into a wintry Monday as temps drop more than 30 degrees. That will kick off another very cold period.

Temps today warm into the low 60s on a strong southwesterly wind. That wind is ahead of a winter storm passing by just to our northwest. That’s bringing more than a foot of snow to areas near Chicago. This will drag a cold front across the state  Showers and a rumble of thunder are possible ahead of this front, with a period of light snow and flurries behind it. Wraparound snow showers and flurries may then kick in through Monday night:

Light accumulations will be possible during this time. The NAM Fam is picking up on the potential:

That’s some very cold air slamming in behind this front. The Hi Res NAM shows the stout temp drop:

Gusty winds will make for a frigid feeling Monday. Check out those wind chills:

That cold is locked in through the rest of the week and could bring a few more flakes into the region late Tuesday and Wednesday. That’s when an upper level disturbance dives in on our northwesterly wind flow.

As the core of the cold starts to lift out later in the week, another system tries to bring rain, snow or a mix our way:

A bigger storm system develops and rolls our way next weekend. While this is likely to take a path to our west, that’s not set in stone. Once that rolls through, a very cold pattern follows.

With this cold pattern through early December, the GFS Ensembles are pretty enthusiastic about snowfall chances over the next two weeks:

Make it  a great Sunday and take care.
