From Sun To Some Snowflakes Next 60 Hours

By · October 20, 2013 at 5:32 pm

Breezy and pleasant early this evening with temperatures still holding in the 60s at 6pm.  Kickoff temperatures for the Battle of 18-12 at LOS will be around 54 and near 50 for folks heading home tonight.  The roof will be open so be sure to take long sleeves and jacket to the game.

Wake up weather Monday will be partial sunshine and lows in the lower to mid 40s.  FutureTrak 13 shows a weak, narrow line of precip in northwest Indiana.  This delineates one of a few cold fronts to impact the Central Indiana this week… and what delivers our first installment of colder than normal air.

All bets off for dry weather Monday by 1-2pm.  Though it’s not a given every city gets showers, it is a possiblity along the front.

Cloud cover exits Monday night into Tuesday morning and sets the stage for one of a few opporutnities this week to get to freezing.  Notice lows Tuesday morning will be some 10 degrees below normal.

The upcoming pattern shift to much colder than normal air has been well documented by the Skytrak13 forecast team.  We also talked last week about the season’s first snow flakes being possible in this air mass.  That’s still in the forecast cards as an upper level disturbance rides the base of a southward digging trough in the jet stream.  Rain showers will mix with snow showers Tuesday night, and likely to change to all snow showers by Wednesday 8am.

Though it’s not unheard of to see flurries or snow showers in October, this is a few weeks ahead of climatogoical norms for Indianapolis.
