The European computers vs. USA models always have problems with storm systems like the one comming up Tuesday. The low that will travel from the southen plains will merge with a canadian low dropping out of the Dakotas. None of the computers models are in agreement at this time. We're gonna get snow, but how much is the big question.

 

[AK9R]

"Great deal of uncertainty" is still the key to the latest from NWS Indianapolis. Central Indiana is going to get snow, but we don't know how much.

We've already got 4" on the ground here in SE IN (near the OH River) since about 1AM, with another 3" expected by 5PM tonight. Fun Fun!

 

[SCPD]

There is a slim chance that a blizzard watch/warning could be issued due to the wind increasing to 35 MPH and the sever blowing and drifting snow and wind chill zero or below. Note weather service has added on its home page now a blizzard watch color tab just to the right of the map witch could be an indication on what they may issue next

While there's a possibility that a blizzard watch or warning might be issued for the NWS Indianapolis county warning area, I think the blizzard watch color tab appears on that map because one has already been issued for a county that is depicted on that map even though it's outside the NWS Indianapolis county warning area.

Benton County (west of Lafayette and north of Attica) is covered by the NWS Chicago office. They issued a Blizzard Watch for Grundy, Livingston, Iroquois, and Ford Counties in Illinois and Benton County in Indiana this morning that is effective from this evening through tomorrow morning. You don't actually see that color on the map because it's overridden by the Winter Storm Warning for the same area.

There's a deep low pressure area moving into the state that will bring significantly colder temperatures to Central Indiana. Terre Haute dropped from 26 to 19 degrees from 2:00pm to 3:00pm. Predicted low temperature tonight for the Indianapolis area is 12 deg. The low will also bring west winds of 15-25 MPH with gusts to 35 MPH. Throw another log on the fire!
