Cold and getting much colder the next 24 hours in central Indiana, as the core of arctic air blankets the Ohio Valley.
You could definitely feel the difference outside Sunday, with a steady diet of northwesterly wind delivering a 20°-25° temperature change compared to Saturday afternoon. Sunday was much colder, but as expected the true arctic air stayed just north of Indiana.
That changes on Monday as a secondary front sinks southward and delivers some of the coldest temperatures we’ve had in central Indiana in a couple of years.
Thankfully a blanket of clouds tonight and persistent northwest wind (10mph) will limit raditional cooling. Don’t get me wrong. Upper teens and a wind chill near zero will be cold in the morning… but it could be a lot worse. It will be a lot worse Tuesday morning when the coldest air is overhead, and we’re under a clear sky with lighter wind.
Several areas will make a serious run at zero Tuesday morning. Anything below 5° (low from January this year) will be our coldest temperature since February 2011. Wind chills will be dangerously cold in the -10° to -15° range for kids at the bus stop.
We’re still keeping tabs on the possibility of accumulating snow and/or sleet/freezing rain in the Thursday afternoon/early Friday time frame. It’s still entirely too early in the forecast game, but stay tuned for updates in the coming days.
For confidence remains high on another bout of frigid air returning in the wake of that system for next weekend. We’re in for the long haul regarding below normal temperatures.
Have a great evening and thanks for reading the blog.
