.LONG TERM /Tuesday through Friday Night/...

Issued at 258 AM EST Sat Jan 27 2018

The focus of the extended period remains on the upcoming storm
late in the week. But first, dry conditions will prevail from
Tuesday through Wednesday with high pressure over the region. The
ridge will start to break down though on Wednesday afternoon as a
low pressure system traverses Ontario. After normal temperatures
on Tuesday, Central Indiana will fall into a warm sector on
Wednesday with high temperatures climbing into the mid to upper
40s. Rain will start moving into the forecast area by Wednesday
evening, gradually transitioning to a rain/snow mix and then snow
(north) on Wednesday night. High variability remains in snow
totals this far out since most of the forecast area will be under
a wintry mix for most of the system. It won`t be until Thursday
evening when the cold air on the back side really settles into
Central Indiana. But by then, the best moisture will already be
out of the area, limiting snow totals. However, any shift in the
system, could have a huge impact on snow amounts during the
Wednesday to Thursday time frame.
