Warm Weekend - Wintry Change Likely Late Next Week!

So far we are on our way to the 3rd warmest December's ever in Indy, but, a MAJOR pattern change late next week could change that. Our pattern is finally looking better for cold and snow lovers, likely right in time for Christmas. Several systems to track from now until then, so let's get to the fun.

Some Rain Saturday, Warm & Dry Sunday: A storm system currently to our southwest will lift to the northeast and track north of us, bringing rain and balmy temperatures for the weekend. Since the storms' center will be well north of us, the best chances of widespread rains tomorrow will be across northern Indiana, but everyone has a decent shot of getting a little wet. Temps will be mild despite the showers, in the 50's. The forecast has really changed for Sunday! It appears a drier air mass will move in and end all rain chances. It will be VERY warm and breezy, highs near 60 degrees. Bottom line, Sunday will be a good day to be outside. 

Temps Up & Down Next Week, Flurries Tuesday, Arctic Air To End The Week? A cold front sweeps in behind the weekend system Sunday night, with cooler air moving in for the beginning of next week, but still staying slightly above average. The next system to watch will arrive Monday night into Tuesday. This disturbance is NOT expected to be a big deal at all. It looks like a few showers are possible Monday evening, then any precipitation leftover could change to flurries for Tuesday morning. The NAM does hint at a few flurries Tuesday morning. Tuesday will be chilly, with highs only around 40.

We will begin to see temperatures warm up Wednesday and Thursday, ahead of a strong storm system that is expected to draw ARCTIC AIR behind it, (easily the coldest of the season) by next Friday. Check out this image from the European model during this time, showing a powerhouse system over the area.

Look at that COLD air that is expected to invade the central, southern, and eastern U.S. by next weekend! Several days of highs in the 20's and snow showers would be possible with this set-up. That cold air mass should hold into Christmas Day as well. So will it be a white Christmas? That remains to be seen. At least we know that it's going to be cold, so anything that falls from the sky would be snow. More on this over the next several days.
