The Shift Begins…
Every year is a bit different, but typically at some point between late August and early September we get that 1st cold frontal passage that serves as a reminder a new season is upon us. This year, that frontal passage is today.
As the front continues to sink south, we’ll notice increasingly dry air building in to close the work week. Dew points will fall into the 50s by this afternoon.
Cooler air will accommodate the drier air mass. Lows across central Indiana will fall into the lower and middle 50s (not totally out of the question a few communities fall into the 40s) both Saturday and Sunday mornings.
Dry conditions will prevail today and Saturday, and most of Sunday, too, for that matter. Our next storm system will lead to an increase in cloudiness Sunday PM and a couple of showers could follow. More widespread rain is anticipated to arrive Monday into Tuesday, and could be accompanied by a few storms. Early indications would suggest we’re looking at 0.50″ to 1″ with this system.
This will be ahead of a stronger trough that will serve to reinforce the unseasonably cool air as we head into the Labor Day weekend. If you’re a fan of this weekend, you’ll absolutely love what’s on tap next weekend (shave off a few more degrees both for lows and highs)!

Meteorological Fall Set To Kick-Off Cooler Than Normal?
With only (11) days left in meteorological summer, thoughts continue to focus more on the upcoming fall season.
While fall foliage is still 5-6 weeks away from “prime time,” medium range computer models continue to suggest the new season will kick off on an unseasonably cool note.
Meteorological fall begins Sept. 1st and runs through the end of November. With that said, you don’t need me to tell you that Labor Day can still produce “summer-like” heat around these parts. On average across central Indiana, we’d expect Labor Day weekend to produce highs in the lower 80s and lows in the lower 60s.
That might be a different story this year as a negative EPO pattern dominates. The end result will likely feature a rather anomalous trough digging into our portion of the country to open up the new season. This is supported with solid agreement between the GEFS and EPS as shown below:
This will likely result in temperatures around 10 degrees (F) below average and most certainly serve as notice that a new season is upon us.
Now will this be an official end to summer-like warmth? Likely not, as there are reasons to believe unseasonably warm weather will build back into the region behind this cool blast. While we don’t want to use this post as our official fall outlook, despite it likely feeling very much like fall as the 1st full weekend of college football kicks off, we think there’s likely more warmth in the tank before we can signal the “all clear” on Summer ’19…

Unsettled Weather Returns; Looking Ahead To Another Beautiful Weekend…
High pressure will remain in control of our weather to open the new work week, keeping most of the area dry. We do note the latest high resolution guidance pops a few showers later this afternoon, but these should remain isolated at best (not even worth changing that “partly cloudy” icon on the 7-day ;-)).
That will begin to change tomorrow as the first of a series of frontal systems begins to impact our weather. We anticipate showers and thunderstorms to become scattered-to-numerous Tuesday afternoon and evening.
Rainfall amounts won’t be “uniform,” but there will be some locally heavy downpours scattered about the region.
A second front will blow through the state Thursday afternoon with additional chances of scattered showers and thunderstorms.
While it certainly won’t rain the entire time over the upcoming few days, areas that need moisture will be in luck with a good shot of picking up between 0.40″ to 0.80″ on a widespread basis. There will be locally heavier amounts in excess of 1″.
Once Thursday’s front pushes south, high pressure will arrive in time for the weekend and will supply another beautiful stretch of weather by mid-August standards.
Looking further ahead, the more active pattern will continue into next week with the potential of a fairly strong system impacting the Midwest, Ohio Valley, and Great Lakes early to mid next week. This would be the system referred to last week as the one that could really serve as a reminder Fall is just around the corner (rain and storms followed by a gusty northwest wind and September-like air). We’ll continue to keep an eye on things!

VIDEO: Changes On The Horizon…
While the weekend will remain quiet and very pleasant by early-August standards, there are significant changes on the horizon that will help drive a cooler and increasingly active pattern as we rumble into next week and beyond.
With that said, high pressure will dominate our weekend weather- supplying plentiful sunshine, warm temperatures, and low humidity.
This morning’s video link has the details on the changes that loom:
