Thursday Forecast: Big Time Cool Down To Close The Week!

Updated 09.11.13 @ 10:06p

Zionsville, IN After three brutally hot late summer days, I know most are looking forward to a big time change for the cooler as we close out the work week and head on into the weekend!  We talk temperature changes, slim chances for some badly needed rainfall, and another stretch of heat next week!

7day091113

Cold Front Blows Through Later This Morning: A strong cold front will usher in a true taste of autumn just in time for another special football weekend ahead!  We bracket the wee morning hours through late morning for the chance of a shower or embedded rumble of thunder as the cold front blows through central Indiana.  That said, we’re only looking at a broken line of precipitation and don’t think every neighborhood gets wet.  Those that do see rain, don’t look for anything too terribly impressive, with most precipitation totals under two tenths of an inch. Winds will then shift out of the northwest and gust upwards of 20 MPH during the evening, helping the drastically cooler air settle in. Temperatures will actually fall during the afternoon, after early highs in the upper 70s.

Brilliant, Fall-Like Late Week: Despite a few puffy cumulus clouds Friday, expect dry conditions extending into Saturday with lots of sunshine. Temperatures will run roughly ten degrees below normal. In fact, Saturday morning will be particularly chilly, especially considering the simmering heat earlier this week. Some outlying communities will likely fall into the upper 30s. Highs both Friday and Saturday will only make it into the upper 60s. – Sounds like a perfect weekend to grab a Pumpkin Spice Latte prior to kickoff of your favorite football team!

Sunday Shower? A weak cold front will slide through the region Sunday evening. Clouds will increase with this boundary and we’ll keep an eye on precipitation chances as we move forward. That said, for now, we only think a widely scattered shower is possible Sunday. Most stay dry.

Resurgent Warmth Next Week: As we’ve been saying for weeks, we’re still in a warm pattern, overall, and don’t see any significant changes until potentially late in the month (say the last 5-7 days). Ridging rebuilds by the middle part of next week and moderating temperatures will ensue. We anticipate highs flirting with the 90 degree mark by Wednesday.

Wednesday Jet Stream Discussion

We use the Jet stream as one of many tools to help us forecast the weather in the days to come. A new feature here at IndyWx.com will be a Jet Stream Discussion, updated a few times every week to help you, the viewer, get a better idea of what to expect in the week ahead!

Note that the upcoming (7) day period will feature many “ups and downs” in the jet stream pattern.  This is indicative of the changing of the seasons and very typical of the approaching fall season.  Unseasonably cool air will be associated with the dip (known as a trough in the meteorological world) in the jet stream Thursday through Saturday. Temperatures will fall through the day tomorrow, after morning highs in the middle to upper 70s, and Friday and Saturday will feature air temperatures well below normal (by some 10 degrees).  That said, the cool weather is “transient” and will be out of here almost as quick as it arrives.  We’ll warm back to seasonable and above average levels during the early to middle part of next week as ridging builds into the Mid West and Ohio Valley region.  In fact, temperatures well into the 80s to near 90 degrees can be expected by the middle/ latter part of next week.

As for precipitation, we anticipate a broken line of showers and embedded thunder to push into the region with the cold front later tonight and Thursday (not a big deal and most won’t get wet). On average, those that do see rain will only muster a couple tenths of an inch.  The next best chance of precipitation isn’t until late next week.

We hope you enjoy these hand drawn maps.  The way weather information is provided to you, the viewer, seems to become more and more digital with less of the “human influence.” Our goal, as always, here at IndyWx.com is to keep the human element in the forecast products you see here.

Our full forecast package will be updated later tonight.  Have a nice and relaxing Wednesday evening and be sure to follow us on Twitter- @indywx or like us on Facebook (IndyWx.com).
