After a damp and chilly open to the weekend, drier air began to infiltrate the region this afternoon and led to a brighter/ warmer finish to the day. We’ll add more sunshine and tack on a few degrees to the afternoon high on Sunday. It’ll be a phenomenal weather day across central IN, thanks to high pressure. Get out and enjoy it!
Dry and sunny weather will greet us to open the new work week, along with temperatures that will approach the 80 degree mark by Tuesday. Have yard work to get caught up on? Take advantage of the early week weather.
Things will begin to change towards an unsettled regime as early as Tuesday evening/ Wednesday as the region gets into an increasingly moist southwesterly air flow.
As such, we’ll increase the chances of showers and thunderstorms in our mid week forecast. It’ll also be a much more humid feel of things (really for the first time this year) as surface dew points surge into the upper 60s to lower 70s. (In other words, “oppressive”).
Factor in PWATs (precipitable water values) zooming to 1.5″-1.8″ and the threat is there for localized heavy downpours around mid week.
Additionally, we also note the Storm Prediction Center (SPC) has placed western sections of our forecast area in a risk of severe weather Wednesday. We’ll keep a close eye on things.
As we progress into the late week period and on into the long holiday/ race weekend, a warm, humid, and unsettled time of things is expected to continue. It’s tough to pinpoint specifics from this distance, but just keep note of the threat of thunderstorms into and through the upcoming busy weekend, along with warm (highs in the lower to middle 80s; lows in the upper 60s) and humid conditions.

Through the first half of May, temperatures are running more than 2 degrees below average at IND. We’re in the middle of a rather large area of below normal temperatures from the SW into the NE region.
We’ll remain below average through the upcoming week, but temperatures will begin to moderate over the weekend into next week.
In general, we agree with the temperature anomalies above, courtesy of the GEFS. As noted, the cool start to the period will moderate and turn warmer next week. Unfortunately, that warmer trend won’t last and it’s likely we trend cooler around the Memorial Day weekend.
In the shorter range, light rain will spread into central IN late tonight into Tuesday. Rainfall amounts won’t be significant, and should be generally around 0.25″, or less.
Drier air is still expected for mid week, as high pressure builds into the region. Needed sunshine and pleasant conditions can be expected.
As we look forward to the weekend, modeling is still at odds with one another. The European remains consistent on the idea of heavy rain while the GFS remains consistent on a drier solution (rain, but much lighter amounts). That said, we note the consensus of the GFS ensemble members is more aggressive and reflects the idea of the European. We’ll remain firm on the idea of potentially heavy rain building in Friday into Saturday.

1.) The month of May has gotten off to a chilly start and given the period of unseasonably chilly air that looms later this week, it’s safe to say these cool anomalies will grow even cooler.
The coolest day looks to be Saturday with highs only in the mid 50s.
2.) In the shorter term, we’re keeping an eye on strong-severe thunderstorm potential this afternoon and evening across southern and central parts of the state. Large hail and damaging straight line winds are of greatest concern, but a quick spin-up tornado can’t be ruled out.
Not everyone will see heavy rain amounts today, but a few neighborhoods may deal with localized flooding issues as slow moving heavy storms potentially train over communities. Where this happens, 2″+ rain totals are a good bet by midnight.
3.) Forecast models remain in a state of disagreement concerning late this weekend into early next week. The GFS is particularly bullish on the idea of wet (heavy rain threat), chilly times whereas the European is much drier (and warmer). We’ll keep an eye on things and hope for consistency this afternoon. Speaking of this afternoon, we’ll have our updated 7-day posted later today! Make it a great Tuesday.
