Sunshine Should Make An Appearance Today…The weekend is opening chilly, including wind chills around freezing this morning. Hang in there- sunshine should at least make an appearance later on this afternoon and Sunday certainly looks to be a brighter day, overall, before clouds increase late and give way to showers overnight into Monday morning.
We’re back to sunshine Tuesday before a stronger storm begins to impact the state Wednesday. A rather robust area of low pressure will track into the Great Lakes region Wednesday night and help pull a briefly warmer, increasingly moist air mass into the area. Potential is present for strong to severe thunderstorms Wednesday evening into the nighttime. We’ll then transition to a much cooler regime to close the week and with low pressure slowly pivoting through the Ohio Valley, showers will continue Thursday into Friday. In fact, the air may grow cold enough to allow for a few wet snowflakes to mix with the rain by Friday morning.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 1.75″ – 2.25″
Highlights:
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.
Highlights:
Precipitation is running above normal, locally, to the tune of nearly 1″ month-to-date. Heaviest rains have fallen across southeastern Indiana over the past (30) days.
A look at precipitation anomalies across the mid west, month-to-date:
As we progress through the upcoming (10) days, a transient weather pattern will persist. This will keep forecasters busy, but it should also be stressed it’s not all a “doom and gloom” type pattern, either. There will be plenty of dry time over the upcoming period, including drier conditions building in tomorrow (Tuesday) into a good chunk of Wednesday.
However, timing is our friend this go around as upper ridging develops over the upcoming weekend. Not only will we dry out, but we’ll also enjoy increasing sunshine as the weekend progresses.
That said, looking further down the pipe line, another (potentially more significant) storm system looms during the 8-10 day period. This would fall in the April 3rd-4th time frame. From this distance, models are bullish on hefty rainfall totals with this storm system and we’ll keep a close eye on things as time draws closer.
Speaking of April, our overall thoughts for the fourth month of the year (where does time go?) would imply a warmer than average month and active (wetter than average). Relative to average, we feel we still may have some chill to traverse early month, but there’s also some indication we could bust into an early summer-like feel mid and late month. With the mean trough position west and ridging east, we’ll have to also be mindful for the potential of an active severe weather month- especially mid and late month. Overall, the CanSIPS idea below is one we would agree with from a mean 500mb perspective.

Highlights:
2.) Speaking of cold, to-date, March is running slightly colder than average (by 1.1°). Note the spring and summer-like warmth across the SW. “Pieces” of that warmth will eject northeast in modified fashion late March into April.
3.) High pressure will supply a dry, but cold Wednesday. Highs will run close to 10° below average (lower 40s), but at least we’ll enjoy the sun!
4.) Temperatures will begin to warm as we progress through the latter portions of the week. We’ll be near seasonal norms Thursday (low 50s), and above normal Friday into the weekend (mid-upper 60s). With the warmer air, rain and storm chances will also be on the increase. As of now, we target best rain chances late Saturday into Sunday. A couple thunderstorms are also possible. Rainfall totals of 0.50″-1.00″ seem like a good bet with locally heavier amounts.
5.) This is just the beginning of an active stretch of weather to wrap up the month of March. (3) additional storms will have to be monitored next week. Accordingly, precipitation anomalies will run above normal.
