Thursday starts with a cold kick, with wind chills in the 20s. The actual Indianapolis temperature dipped into the 20s for the first time since the 29th of November.
Don’t sweat the small temperature stuff. Winds shifted from north to east yesterday evening and will now switch to the southeast, pulling in milder air.
High clouds have also been streaming in, way out ahead of the next weathermaker. You’ll see the base of those clouds up around 25,000 feet in the morning, and lowering and thickening throughout the afternoon.
Rain chances start after midnight tonight, and they don’t stop completely until Tuesday. There are two waves that offer the best chances. One is Friday. The other is Saturday night through Monday morning.
As the precipitation leaves and cold air arrives Monday there will be a switch from rain to snow. A dusting is possible, with maybe an inch or less by Monday afternoon from around Lafayette to Kokmo, north to Michiana.
Yesterday I got to speak to a class at Anderson University, thanks to Professor of Chemistry & Physics Scott Carr. One of the topics in the Q&A was the effectiveness of Super Storm Sandy warnings. I mentioned that there was some confusion, since “Hurricane Warnings” were never issued, due to the post-tropical nature of the storm.
Well. I read early this morning that following the criticism of the National Hurricane Center’s handling of Hurricane Sandy they have decided that the NHC will now have more flexibility in their policy regarding the issuance of advisories.
From now on a Hurricane Warning may fit this criteria: An announcement that sustained winds of 74 mph or higher are expected somewhere within the specified area in association with a tropical, *sub-tropical*, or *post-tropical* cyclone.
The average high today is 42 and the average low is 27. Records are 73 and -1. The sunrise time is 7:52 and the sun sets at 5:20.

Yesterday’s high was 46. The forecast was 46.
