Pattern Progression Into Early September…

The short-term period will be dominated by a cooler than normal theme as we put the final touches on August and open September.

This will only serve to push those already below normal for the month even cooler than average and turn a lot of the area bordering these cool anomalies “over the top” from seasonal to slightly cooler than normal by month’s end. Meanwhile, warmth will continue to dominate along the coasts

Here’s a look at month-to-date temperature anomalies, compared to our initial August forecast (issued July 21st).

The negative EPO suggests any sort of warmth will be hard to come by and transitional through the 1st 1/3 of the month.

After a wet time of things as of late, we’ll dry things out the middle part of the week. A couple of moisture-starved and rather weak systems may lead to scattered showers Friday and again at times over the holiday weekend, but significant rain isn’t anticipated. We would agree with the drier than average theme displayed from the most recent CFSv2 Weekly product to open September:

The one potential “fly in the ointment” to the dry open to September would be whatever comes from current Tropical Storm Dorian (moving through the Windward Islands as of this update). There’s relatively good model agreement that Dorian will move northwest and eventually be in a position to impact the eastern Florida coastline by the Labor Day weekend as a Tropical Storm.

It’s far too early to speculate from this point, but the pattern may promote Dorian to then track into the Gulf of Mexico. While unlikely Dorian’s remnant moisture ever impacts our immediate region, this will be something that we’ll keep an eye on over the next week to 10 days.

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.

This was a photo I snapped in the Eagle Creek community back in October of 2013!

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…
