The combination of an approaching cold front to our north and remnant tropical moisture from Cindy will serve to enhance rainfall amounts across central Indiana late tonight into early Friday evening.…

I. Drier and Cooler Air Returns: A cold front will pass this evening and allow a much less humid and cooler air mass to return to the state. Dew points will fall into the 50s by Monday morning and highs should only reach the upper 70s to around 80 Monday afternoon. Refreshing air will remain in place through the day Tuesday.
A much less humid air mass will arrive to open the work week.
II. Watching the Gulf: All eyes will be on the Gulf of Mexico this week as it tries to breed early season tropical “mischief.” There are many more questions than answers right now concerning the all-important details (ultimate track and strength), but confidence is high on a depression or storm forming in the Gulf by middle to latter portions of the week. Early thinking would place more emphasis on this being a big inland rain event across portions of the southeast, as opposed to this thing ramping up fast enough to be a big wind/ surge problem, but stay tuned.
Confidence is high on early season tropical development this week in the Gulf of Mexico.
III. Unsettled Weather Returns: A storm system will approach the region by the latter portions of the work week, including the weekend. As a result, a warmer and increasingly moist air mass will return and help spawn showers and thunderstorms. Unfortunately, timing isn’t our friend as numerous showers and thunderstorms are forecast Friday-Sunday. Locally heavy rain is also a good bet.
Heavy rain and storm chances increase late week.
IV. June Ends On A Cool Note: Once we get rid of the significant storm next weekend, an unseasonably cool air mass will build in over the Great Lakes and Ohio Valley in the 8-10 day time period. How do highs in the upper 60s to lower 70s sound and lows in the middle 50s?
Models agree on an unseasonably cool close to June.

The new JMA Weeklies are in and highlighted by the following:
Week 1:
The JMA Weeklies really try to emphasize the “transient” nature of the pattern and associated dry, hot weather some folks were becoming concerned about only a couple of days ago. Week 1 is highlighted by a much wetter regime through the Ohio Valley and most of the East. As the ridge pulls back west, a cooler regime returns to our region, while the Southwest bakes with anomalously hot weather.
Week 2:
The pattern favors wetter than normal conditions across the upper Mid West, including Great Lakes. The mean upper ridge is forecast to remain out west. Fittingly, the warmest temperatures, relative to average, will be confined to the west.
Weeks 3-4:
As we push into July, the upper pattern sets-up in a manner that will require us to keep a very close eye on storm potential. With a northwest flow aloft, we’ll have to be mindful of the potential of storm clusters impacting the region- tracking northwest to southeast. Through the balance of the period, the hottest weather should remain to our west, relative to normal.

The Storm Prediction Center includes the northwestern portions of the state in a Slight Risk of severe weather later this afternoon and evening. Given the overall set-up and morning trends from data, it wouldn’t surprise us if this threat expands further southeast in future updates later today from the SPC.
Similar to Tuesday, any storms that develop will be capable of locally heavy rain and flash flooding. While storms should move in a quicker fashion today, precipitable water values (PWATs) remain downright tropical and will exceed 2″ later this afternoon.
Overall storm coverage should become more widespread as we push into the afternoon and evening hours. Here’s what the radar may look like during the 4p, 6p, and 10p time frames:
From a severe perspective, the biggest concern is damaging straight line winds with stronger storms. Remain weather-aware later today, friends!
