Storms To Snow This Weekend…An approaching storm system will lead to an active open to the weekend.  Beforehand, thankfully, we’ll close the work week out on a rather quiet note.  The daytime hours will remain dry before moisture begins to return this evening.  An initial round of showers will move across central Indiana (thinking between 8p-9p) before steadier and heavier rain and embedded thunderstorms blow into town Saturday.  A strengthening surface low will move from the central Plains tonight and into the southern Great Lakes Saturday.  This will lead to a briefly milder surge of air Saturday morning into the early afternoon before a cold front sweeps through the state and leads to a sharply colder close to the day.  Right ahead of the cold front, a skinny, but potentially intense, line of thunderstorms will track across central Indiana late Saturday morning into early Saturday afternoon.  Damaging wind gusts are possible as this thin line of storms advances across central and southern Indiana.  Winds will then shift around to the northwest and help drive much colder air into the region through the afternoon and evening.  In fact, we’ll turn cold enough to allow precipitation to end as a touch of wet snow Saturday evening.

We’ll wrap up the weekend and kick off Thanksgiving week on a much calmer note.  Chilly high pressure will build in Sunday, allowing sunshine to return, but temperatures will run around 15° below normal.  A dry cold front will pass through the state Tuesday.  With the exception of a wind shift and a few more clouds we really shouldn’t expect much more in the way of “excitement.”  This will allow unseasonably cool air to return for Thanksgiving, itself.
