Central Indiana is bracing for the possible effects of a massive winter storm.
The storm is expected to bring widespread blizzard conditions from Colorado to Wisconsin. Blizzard warnings were issued for seven states late Wednesday afternoon. The snow is expected to fall at a rate of 1-1.5″ per hour out West. Strengthening winds with gusts up to 60 mph are also expected in the overnight hours across those states.
Locally, Central Indiana will be on the front side or warm side of this storm initially. A warm front will push north later Wednesday night, bringing a few scattered showers in the evening. Temperatures are expected to start rising later and climb into the middle 50′s before the first of two cold fronts pass.
A steady rain and even a few rumbles of thunder will develop after 3 a.m. in Indianapolis and spread northeast through sunrise. The mature storm will then cut off the rain as we enter the “dry slot” of the storm.
A region of the storm where strong jet stream winds roar overhead. The air will sink, cutting off the precipitation at the same time winds begin to ramp up. Wind gusts of 40 to 50 miles per hour are possible Thursday evening and night.
A second cold front will trigger snow showers and usher in the coldest air of the season during the overnight hours Thursday night into Friday morning. These backlash snow showers on the rear of the storm could bring local accumulations of around a 1″ by daybreak Friday. A Winter Weather Advisory has been issued for most of Central Indiana through Friday morning.
