Today certainly won’t be a “chamber of commerce” like day across central Indiana as we deal with numerous mixed rain and snow showers. Already this morning, reports of wet snow are coming in to the forecast office from Whitestown, Lebanon, and Crawfordsville.
We’ll also add wind into the mix late morning through early evening, including gusts around 50 MPH. Factor in the much colder temperatures with gusty northerly winds and you have the makings for a truly “raw” day across the region. The National Weather Service has issued a Wind Advisory until 8pm.
We should finally get rid of the precipitation later tonight and after a chilly Friday, weekend improvements are coming. Lows both Friday and Saturday morning will be around freezing for most central Indiana neighborhoods. After a cloudy start Friday, sunshine should return Friday afternoon as drier air works into the region. With high pressure arriving this weekend, sunny conditions can be expected and with a southwest wind developing by Saturday afternoon, moderating temperatures are on deck as well.
In fact, after that cold start Saturday, highs should climb into the lower 60s Saturday afternoon and all the way into the lower to middle 70s Sunday afternoon!
Our next storm system will push into the Ohio Valley early next week with scattered showers and thunderstorms Monday into Tuesday.

2.) We’ll get a breather on Tuesday, but our next storm system will move in quickly and begin impacting central Indiana during the day Wednesday. A couple strong to severe thunderstorms are possible Wednesday and will require our attention over the next day, or so. We’ll have more details with our updated 7-day later today.
3.) We’ll get into the colder side of the storm to close the work week and thoughts will shift from storms to snow. Wind-whipped snow showers will be a good bet in the unseasonably cold air Thursday into Friday morning.
4.) Timing will once again be our friend as we push into the weekend. Weak high pressure will arrive on the scene and help ensure dry conditions. After a cold start Saturday, a moderating trend will develop.

2.) We bracket the hours of 2p-8p (couple hours earlier from yesterday’s thinking) as the period of potential most widespread strong to severe thunderstorms across central Indiana, and the HRRR forecast radar shows what the radar may look like this evening. Have a means of getting the latest warnings.
3.) Scattered showers will continue into Friday morning before drier air arrives during the evening hours.
4.) This drier trend Friday PM is one that will continue into the weekend. High pressure will supply mostly dry weather through the entire weekend (small shower chances return Sunday evening), including sunshine.
5.) Another active period of weather awaits next week, including multiple rain chances early and late week. The latter storm looks to be the bigger event with heavy rain and thunderstorm potential Wednesday into Thursday. 7-day rain numbers check in between 1.5″-2″ with locally heavier amounts.
6.) The story becomes a chilly one next weekend, and models suggest central Indiana may be dealing with frost and freeze conditions by next Saturday or Sunday morning.
Multiple rounds of showers and thunderstorms will likely impact central Indiana through the mid and late morning hours Thursday.
As we press into the early afternoon hours, model data suggests we see a “lull” in the stormy weather and potentially even a few breaks in the cloud cover. This would serve to “up the ante” in regards to the prospects of severe weather potential Thursday afternoon, particularly mid and late afternoon through the evening hours. Accordingly, the Storm Prediction Center continues to highlight central Indiana for the risk of severe weather Thursday.
In fact, given a look at the most recent data, I wouldn’t be surprised to see the “enhanced” risk area expand further north in future updates. This would also include all modes of severe weather (large hail, damaging straight line winds, and potentially a tornado). As things stand this evening, we bracket the hours of 4p and 10p Thursday for the greatest potential of severe weather.
As we push into the overnight hours Thursday into Friday, unsettled weather will continue, but we’ll get rid of the severe potential. “Nuisance” type showers will continue into the first half of Friday before drier air arrives Friday afternoon and evening. This drier theme will settle in for the weekend and provide a very pleasant open to April.
