ARCTIC AIR IS BOTTLED UP FOR NOW
Arctic cold to remain on hold for now. Today marks 6 straight days above normal. Our young winter is now a half-degree warmer than last year to-date.
As forecast early last week, we've lost the connection to the polar branch of the jet stream. The bitter cold looks to be bottled up for now. A milder, split-flow jet stream bathes the nation in milder air with origins off the pacific and not from the arctic. The overall look is a higher probability of above normal temperatures through the end of the year.
SNOW SEASON OFF TO A SLOW START AGAIN
The snow season is once again off to a very slow start. Less than 1" of snow has fallen officially in Indianapolis through the 17th of December - that's 3.3" below normal. This is among the least-snowiest starts to a snow season on record (24%), ranking 33rd all-time. Only 1998 produced no snow through the 17th of December, not even a trace. It is interesting to look at some cities that have had more snow already this season.
ANY CHANCE OF SNOW BEFORE CHRISTMAS?
We are not out of the running of a snow that sticks before Christmas just yet. Late in the week a wind-driven, storm system could produce a rain to snow that sticks per the overnight long range computer runs. We will track this storm system for the rest of the week!
