Clouds break for some peeks of sun this afternoon, but temperatures remain cold in the 20s.
Though we are already eyeing our next snow-maker, it will not arrive until after the evening rush hour. However, the quick-hitting system shows up nicely on radar with an area of snow in the Central Plains. This upper disturbance will race across Central Indiana overnight and drop a comparatively (to last week) light accumulation.
Snow will be flying by midnight and increase in coverage along and south of the I-70 corridor. Notice the sharp cut-off in snow, and the north side of Indianapolis may very well be the dividing line.
Snow will taper to flurries by 8am, but the damage will be done prior to the morning commute.
Don’t get caught up in “amounts”, because make no mistake this will be light. But the timing (between 10pm Monday and 8am Tuesday) and temperatures (lows in the teens by 8am) spell trouble… as any snow will create an icy glaze where it does fall. NOT SET IN STONE, but the early is for a dusting to 1″ for Indianapolis, and the best “chance” of an inch to two inches will be just south of I-70. This includes Shelbyville, Columbus, Bloomington, Martinsville, Greensburg, Rushville and Connersville to name a few.
But remember that even a dusting can make the roads slick as temps settle into the lower teens.
School delays are possible, and wind chills near zero for those that must be at the bus stop.
This is one of a few Arctic fronts to impact the Ohio Valley between now and Thursday morning. Each will reinforce the already unseasonably cold air in place.
A bigger system is lurking for this weekend, and early indications suggest a robust moisture field to play with. Obviously this far out there is much uncertainty… but snow accumulation is possible Saturday and models (for now) hint at heavy snow potential. Stay tuned for updates this week – Sean Ash
