Well-Advertised Major Changes Waiting On Deck…

Thursday will begin the major shift from relatively mild and stable weather that we’ve enjoyed for the past week and a half to one that’s drastically different, and much more resemblant of November by Saturday.

First rain drops will likely splatter on wind shields as early as the morning commute across central Indiana.

We’ll then see a “lull” in the action through the majority of the day before more widespread showers and embedded strong to severe thunderstorms rumble in Thursday night into Friday morning.  Here’s a look at forecast radar Friday morning.

The Storm Prediction Center does highlight western sections of the state for a Slight Risk of severe weather Thursday.  We’ll continue to monitor things closely.  Localized damaging straight line wind is the primary severe threat in the highlighted risk area.

We also want to highlight Friday afternoon and evening for another round of showers and embedded thunder.

Rainfall totals should reach between 1″-2″ with locally heavier amounts between the period of Thursday morning and Saturday morning.

The rain and gusty storms will fall ahead of a strong autumn cold front that will send temperatures on a rapid downward trend come Friday night.  A deep trough will carve itself out over the eastern region Saturday and ultimately have temperatures all the way to the Gulf Coast feeling November-ish by Saturday (perfect football weather, IMO).

By the way, the record low max will be in jeopardy Saturday (49 degrees, courtesy of Sean Ash) as many central Indiana communities may struggle to make it out of the 40s for highs with considerable cloudiness, pesky drizzle, and gusty winds.  Have the jackets and sweaters ready, friends!

Cooler Breezes Blowing…A strong cold front moved through the region last night.  You’ll notice a huge change in the air mass upon stepping out the door this morning with north winds blowing!  This will really be looked at as the first true fall cold front of the season with the coolest air in months blowing in for late week into the weekend.  Today will feature some breaks in the clouds late morning into the afternoon, but cold air advection will lead to continued mostly cloudy skies for the better part of the day.

Reinforcing Chilly Air…A reinforcing push of unseasonably chilly air will blow in Friday night into early Saturday.  A couple of light showers will be possible as the cold front passes and even cooler air will pour into the area Saturday (temperatures will remain in the 50s for a large portion of the day Saturday).

We’ll dry things out and introduce sunshine into your Sunday forecast.

Mid Week Cold Front…Another cold front will target a Tuesday evening/ Wednesday arrival (and departure :-)).  We think moisture will come at a premium with this next front so we don’t forecast any sort of heavy rain at this juncture.  Another push of cool air will move in behind the boundary.

7-Day Precipitation Forecast:

  • 7-Day Rainfall Forecast: 0.25″ – 0.50″
  • 7-Day Snowfall Forecast: 0.00″
Get ready for a MUCH cooler day!  Highs today have already occurred shortly after mid night, and will struggle to top 67 later this afternoon in the city, itself. This is only the beginning of an extended stretch of cool air.

Decreasing Rain Coverage; Increasing Sunshine…A shield of moderate to heavy rain encompassed the state during the overnight.  This shield of rain is slowly moving east, southeast and we’ll be looking at improving weather through the day.  There’s still the chance of a widely scattered thunderstorm late morning or early afternoon as a frontal boundary slides through the region.

Sunny Days…As we progress through the mid and late week stretch, we’ll enjoy dry skies and plentiful sunshine.  Normal lows and highs are in the lower 60s and lower 80s this time of year, so we’ll be very close to that Wednesday before moderating temperatures take us warmer than average to wrap up the work week.

Late Week Cold Front; Autumn Feel This Weekend…A cold front will slice into the warm and humid air mass Friday evening and lead to the possibility of a broken line of strong to potentially severe thunderstorms.  A MUCH cooler air mass will then invade the region behind the boundary, leading to a true fall-like feel this weekend!

7-Day Precipitation Forecast:

  • 7-Day Rainfall Forecast:  0.50″ – 0.75″
  • 7-Day Snowfall Forecast: 0.00″

John Salewicz sent us this beautiful sunrise photo Saturday morning before storms invaded portions of central Indiana.  Thanks, John!
