Teleconnections are starting to favor very cold snow conditions once we get past the first 10-15 days of January.





EPO is still positive which floods CONUS with Pacific air but it looks like it may tank at the end of the forecast run





PNA staying positive or neutral




AO is strongly negative




NAO staying negative





Strat warming happening with the potential of a Polar Vortex split







Second half of winter could be wild!

Very good news, a back loaded winter hopefully with below average temperatures in February and above average snowfall.

45°F with a 42°F wind chill at 3am, headed to 69°F this afternoon

Today's averages are 66°F/45°F

Starting to seem that way but lets wait and see if this all actually happens because the CFSv2 saying no way or any cold will be very short lived for the eastern 2/3rds

The mid 80's are gone for a while. Looks like near normal temps for the next 10 days.

December in Indianapolis

Average Temp: 34.7F (3.1F above normal) Tied for 46th warmest
Precipitation: 1.63 inches (1.54 below normal) 30th driest
Snowfall: 2.5 inches (4.4 inches below normal) 57th least snowiest
We had 3 days with a high of 32F or less which is 2 days above normal.

To talk about how bad last winter was, our heaviest snowfall in all of 2020 came on December 16th when we received 1.8 inches of snow.


We could see a very light dusting of snow overnight tonight, then things seem to dry out for the rest of the week. Just straight overcast skies with highs in the mid 30s all week.

Of course the GFS has been waffling quite a bit the last couple of runs, the placement of the western ridge will be very critical once the polar vortex actually splits. The 18Z looks far different than the 6Z this morning, all comes down to the details as usual.

We picked up a trace of snow overnight. The snow really only stuck to the grass.

Thursday night we’re supposed to get 1-3 in of snow, and another 1-3 in Friday.
