An early season arctic cold front is barreling through the Midwest Monday morning and is expected to reach the Gulf Coast and the East Coast on Tuesday. Temperatures will be above freezing initially. The cold front is forecast to move east later this week on Tuesday and Wednesday. These include the coldest high temperatures and record low temperatures for both Monday and Tuesday. Lake effect snow showers start after midday and as winds turn to the NNW, it'll start to pile up across Michiana.
The big story will be the colder air behind this system for Tuesday into Wednesday. The problem for the commute will be temperatures in the 20s with some snow (probably only an inch or so) and icing on the roadways...so allow some extra time Monday! There is a little more snow with this one than last week, but it's still not significant.
In Chicago, O'Hare International Airport reported snow, 22 degrees, wind gusts to 30 miles per hour, and visibility of a half-mile at 9 a.m. local time Monday. For example, Mount Snow in Vermont announced it will open Wednesday, while Hunter Mountain Resort in NY will have its lifts running Friday. Lows in the teens are expected as far south as northern Texas and Arkansas. We had to deal with some high clouds today that don't look to depart tonight. The record low for Lake Charles Wednesday morning is 26 set back in 1911, so this will be awfully close to a record. Highs will be in the upper 30s with overnight lows in the upper 20s.
Accumulations are likely in NW Arkansas but warmer ground temperatures will limit traffic issues to bridges and overpasses.
Highs will moderate a bit for the second half of the week but still below the normal high of 61.
