We didn’t see too much of a temperature improvement today due to fog throughout the morning and early afternoon hours.  But temperatures did manage to stay above normal for this time of year and they’ll continue rising slowly tonight.  This means that the temperatures we are seeing this afternoon shouldn’t fall after sunset.  We’ll see about a 1-3 degree temperature climb by Wednesday morning.

Meteogram tomorrowWinds will pick up from the south on Wednesday at 8-15 mph and this will help usher in warmer air.  Temperatures should climb near the 60 degree mark for Wednesday afternoon.  There is still a small chance for showers on Wednesday but any rain would be light and short-lived.  Our cold front is set to arrive Wednesday night into Thursday morning.  This means that temperatures will be dropping quickly in the overnight hours as colder, arctic air invades.  Temperatures on Thursday will only top out around 43°F and that should happen early in the day.

Thursday afternoon night, another push of moisture arrives to central Indiana and this will first start as rain and transition to sleet Thursday evening.  We could see enough sleet to cover the ground and create slippery conditions.  But this is only the beginning of this event.  As temperatures start to drop throughout the atmosphere, this sleet will turn to all snow on Friday.  And the amount of moisture is looking impressive as this moves through central Indiana.

JEN1The weather models did pick up on more moisture today with this system.  The GFS is coming in with the least amount of snow for Indianapolis at 2.5″.  The European and Canadian models have some similarities but are going a bit higher.  The European picked up at 4″ of snow.  These two have been hinting at higher amounts of snowfall, especially in the southern part of the state.  That being said, this will lead to a bump-up in the snowfall expectations.  But please remember.. THIS COULD CHANGE!  We are still 3 days away from this system and it hasn’t even formed yet to get a proper sampling of the airmass.  So stay tuned and we’ll be bringing you more updates with each shift and newscast.

Cold air invades for Saturday and temperatures will only top out in the mid 20s.

Another quick-moving system will move into the Ohio Valley on Sunday and this could bring a wintry mix to the area.  The weather models have gone back and forth on the precipitation type.  I’ve seen everything from rain, sleet, freezing rain to snow.  This one needs more time to mature to get an accurate prediction.
