Mid-October Weather…

Highlights:

  • Widely scattered storms this afternoon
  • Well below average temperatures
  • Overall dry pattern continues

Jackets Required…Hoosiers are waking up to temperatures all the way down into the middle and upper 40s away from the city this morning (sure is hard to beat this crisp fall air).  Sunshine will greet us out the door, but we’ll notice increasing cloudiness this afternoon and widely scattered thundershowers will follow.  Most will stay dry, but enough upper level energy will interact with the cool air aloft to generate “pop corn” variety thundershowers this afternoon and evening.  Additionally, highs in the mid 60s today and Thursday will be more like mid-October than early-September.

There’s no reason to waste a lot of pixels on the rest of the forecast period.  Dry weather will dominate.  Reinforcing cool air will arrive by the weekend and that cooler than average feel will remain throughout the forecast period.  We’ll notice a gusty easterly wind at times late in the weekend and early next week as the pressure gradient tightens a bit between an area of high pressure to our northeast and Irma moving north into the Southeast.

Tropics:  Irma continues to dominate the headlines, and rightfully so.  This morning we have (2) additional storms: Jose and Katia. Jose is forecast to strengthen into a hurricane tonight, but should remain a “fish storm.”  Katia will meander around the Bay of Campeche over the next few days and doesn’t pose a threat to the US.

Irma remains a category 5 beast this morning and overnight data continues to paint an ominous picture for the southeastern coast. Folks from the southern FL peninsula all the way up the coast to include the Carolinas need to remain abreast of the latest developments on Irma in the days ahead.  Tropical storm conditions are expected to begin as early as Friday evening for southern Florida.  Eventually, more of the southeast can expect impacts from Irma late weekend and next week, including interior areas such as the southern Appalachians…

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 0.00″ – 0.10″

Feeling Like Fall…

Highlights:

  • Increasing sunshine
  • Scattered showers Wednesday
  • Cooler than average

More Like October Than September…A cold front moved through the region last night.  As expected, there were “haves and have nots” with the frontal passage, including some rainfall totals over 2″ (especially north and east of the city) while other neighborhoods barely picked up a tenth of an inch.

Northwest winds are blowing now and ushering in much cooler temperatures that will be with us through the forecast period.  In fact, temperatures will turn so cool it’ll feel more like October (especially Wednesday and Thursday) than September.  Additionally, upper level energy will help create scattered showers Wednesday (not a big deal).

Dry conditions will return as we wrap up the work week and head into early next week.  Reinforcing cool air will arrive this weekend and we’ll also note a gusty easterly wind at times, thanks to the circulation between a high off to our northeast and Irma pushing north across the southeast region.

Tropics:  Speaking of Irma, she continues to strengthen this morning and very near category 5 status.  Preparations should be underway across the Florida peninsula now.  We still have time to watch things unfold, but it’s looking increasingly likely that southern Florida will begin to feel tropical storm force winds as early as Friday, followed by a potential landfalling major hurricane over the weekend.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 0.00″ – 0.10″

VIDEO: Severe Potential Tonight, October-Like Chill, And Irma…

The Storm Prediction Center includes an Enhanced Risk of severe weather across north-central parts of the state this evening.  Damaging winds are of greatest concern with the stronger storms embedded in a squall line that will move from north to south this evening (generally between 6p-midnight).

MUCH cooler air will descend into the region as we progress through the week.  Temperatures will be so cool, it’ll feel more like October rather than September, including multiple nights with lows settling into the 40s and highs not making it out of the 60s.

Pleasant Labor Day Weekend; Another Cool Shot Next Week…

Highlights:

  • Dry Labor Day weekend
  • Cold front arrives early Tuesday
  • Another cool shot next week

Improving Skies West To East Today…The remnants of Harvey led to heavy, wind-whipped, rain across southern and southeastern portions of the state Friday.  Appropriately, today is the “transition day” towards brighter and briefly warmer times as Labor Day approaches.  We’ll notice improving sky conditions from west to east today as the remnants of Harvey continue to track east.  Today also won’t be nearly as windy as Friday.  We awoke to temperatures at mid-October levels, including many in the 40s across central Indiana this morning.  Despite the increasing sunshine, temperatures will run around 10° below average this afternoon.

A cold front will approach late Labor Day night and early Tuesday.  Sunshine will dominate Monday, but we will note an increasingly gusty SW breeze by afternoon as the cold front draws closer.  That front will slide through Tuesday and could have a scattered shower or thunderstorm with it as it passes (best chances of storms will be across the southern half of the state).  Behind the frontal boundary, another shot of well below normal air (October-like) will descend into the region.  With cold air aloft and just enough upper level energy around, widely scattered showers are possible during the afternoon hours Wednesday and Thursday.

Tropics:  Irma will dominate weather headlines during the upcoming week.  It’s far too early to know precisely where Irma will track, but folks with interests along the East Coast (from the southern FL peninsula all the way up to the north Atlantic coast) should monitor the progress of Irma closely.  In addition to the likelihood of a major hurricane, the overall size of Irma will become larger as the week progresses.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall:  0.10″ – 0.25″
