Another Cool Period Looming Before We Crank The Heat…

Cooler than normal air masses have been lined up this summer as frequently as airliners waiting to land at Atlanta-Hartsfield airport. With that said, it’s only fitting that we’re targeting…

Wednesday Evening Update; No Reason To Think Any Sort Of Sustained Heat Is In Our Future.

Good evening. The video covers some of the short and mid range details as we move forward.  Dry and cool air will give way to a more humid regime over the weekend.  An active and biased cooler than normal pattern remains in the mid to long range, per the GFS (and European, as well) ensembles below.

Thursday Evening Weather Rambles…

1.) After a relatively dry day (though don’t tell Indy’s northwest communities that) Thursday, rain chances will begin to creep back into our forecast over the weekend as humidity levels…

Still Anticipate Late June Changes…

We asked this question on our Twitter account earlier this morning.  Do you prefer heat and humidity or frigid and snowy?  Here’s a look out the back door from the IndyWx.com HQ from this morning and then back to right after the early January winter storm.  Note the snow depth on the fence line.  Amazing stuff!

Anyway…as we look ahead, we still anticipate an overall regime change as we progress through the upcoming weekend and into next week.

Model data remains in rather good agreement on the evolution of the upper air pattern over the course of the upcoming 7-10 day period.  The GFS is a touch more aggressive on the eastern trough when compared to the European, but both agree on week 2 cooling, as do we.

This won’t be tremendously cool air (such as last weekend), but when compared to averages, we’re likely to cool things back to slightly below normal.

The PSD shows the changes, as well.  Note the current eastern ridge is replaced by the Day 10 eastern trough.

The precipitation idea is one that is continued wet.  Our three primary mid range global models (GFS, Canadian, Euro) agree on widespread rainfall totals of 1.5″-3″ (locally heavier totals where stronger thunderstorms move) over the next 10 days.  Here’s a closer look at the Canadian, thanks to the model suite at Weatherbell Analytics.

Another Nice Weekend In The Middle Of An Unsettled Pattern…

The upcoming 7-10 days looks unsettled overall and quite wet.  That said, we’re set to enjoy another beautiful weekend with a refreshing northeast breeze in play.  We discuss this and look deeper into the month of June in this evening’s video update below!

Latest model data suggests widespread 2-3" of rain could fall across central Indiana over the course of the upcoming 7-10 days.

Saturday Morning Notes…

Afternoon Thoughts…

1.) Model data continues to point towards some impressively cold air for so early in the season as we move through October’s 2nd half.  2.) Latest raw ECMWF numbers suggest highs next week remain in the 40s for (4) consecutive days- beginning Tuesday and continuing through Friday.  This is extremely impressive for so early in the season. 3.) Northern hemisphere snow and ice cover is running well ahead of this time last year.  There have been studies that suggest this helps promote blocking in the winter months ahead.  (Latest image is posted below).  Time will tell…. 4.) We’re not looking at particularly heavy precipitation amounts over the next week, or so, but there will be a few systems that will produce rain and/ or snow showers (yes, snow) between now and this time next week. Model precipitation amounts range from one tenth to one half inch over the next 7-10 days.  5.) There are some hints we may be looking at another surge of even colder air just in time (or around) Halloween.  You may want to invest in a warm costume this year! 🙂
