INDIANAPOLIS – Freezing temperatures are on the way to Central Indiana and the first flakes of the season are on the horizon for some!
Cold blast hits Monday
A lobe of arctic air has broken off the polar vortex and is progressing south through Central Canada. A large area of high pressure to our west will direct the cold air through the Midwest at the surface. Monday will be windy as a result of the advancing cold air. Gusts will peak around 30 mph in the afternoon. It will not warm up much during the day either. Our first high in the 40s is expected and will be within 10 degrees of morning lows. A mostly cloudy sky will dominate a portion of the day with more breaks in the clouds during the afternoon.
First flakes and a freeze warning
A freeze warning will be in effect across Central Indiana Monday night into Tuesday morning. Temperatures are expected to drop below freezing across the state. In some cases, a hard freeze may take place. This could end the growing season. Make sure to bundle up as wind chill values may be as cold as the upper teens & low 20s Tuesday morning!
Beyond just the cold, our first chance to see snow will come Monday night into Tuesday! Cold air aloft will create enough instability that snow showers will develop along the lakes and a quick moving front. Not everybody will see snow in Central Indiana, and it will be minimal or mixed with rain where it does fall. However, it would mark our first snow of the season with up to a dusting in northern parts of our area!
Sharp warm up late week
The cold start will not set the tone for the rest of the week, quite the opposite in fact! The lob of arctic air sitting just to our north will begin to retreat while high pressure slides to our south. This will happen gradually, but by Friday the warm up will be in full swing. Our upcoming weekend pattern will even be conductive for a few days in the 70s extending into the start of next week!
