All eyes turn towards this weekend.

There's a chance of seeing a rain /snow mix this Saturday into Sunday. It doesn't look like anything substantial but it's something wintry rather than having 60 degree days in January. #BOTS!

Here's the latest thinking from the National Weather Service:.Long Term...(Thursday through Tuesday)
Issued at 300 PM EST Tue Dec 28 2021

Thursday Through Thursday Night.

Rain will come to an end across central Indiana late Wednesday night
as the forcing associated with an 850 to 700mb jet exits the area.
Dry weather then briefly returns for Thursday but with the polar air
locked well into Canada, temperatures look to remain well above
average.  Model soundings still show moderate saturation at the mid
levels, so expect at least partly cloudy skies to continue through
the overnight hours before the thicker clouds arrive Friday.

Friday Through Tuesday.

The next rain producing system will move out of the Southern Rockies
and track to the northeast Thursday into early Friday with
precipitation for central Indiana beginning Friday afternoon.
Confidence in the track of the low has increased but there remains
many of the mesoscale features that remain uncertain that will
impact the axis of heaviest rain or the threat for thunderstorms.
Current thoughts are the axis of heaviest precipitation will be
south of the Ohio River with northerly surface flow across much of
the area. This will keep central Indiana out of the warm sector and
keep thunder or strong storm threats to near zero.

If the track inches northward a bit, the southern counties could see
a few thunderstorms. A weak TROWAL may allow for some snow to mix
into the northern counties Saturday into early Sunday after the
initial round of rain, but confidence in both the strength of the
TROWAL and how could the airmass is are both low at this time. High
pressure and seasonable weather then arrives Monday into Tuesday as
high pressure builds across the area.

I saw a picture that summed up the winter pattern we have been experiencing so far. This is why we are in the battle zone between warm and cold air masses.
