All Eyes On Irma…

Highlights:

  • Unseasonably cool weather continues
  • All eyes on Irma
  • Impacts TBD, locally

Unseasonably Cool; Irma Dominates Headlines…Upper level energy did, indeed, spark a couple of showers (even some small hail was reported in stronger showers) Wednesday evening.  Here at IndyWx.com HQ, we picked up a quick half inch of much needed rainfall!  While a couple of showers are possible once again this afternoon, these will be primarily confined to northern portions of the state.  Otherwise, the balance of the upcoming forecast period is easy through the weekend: dry with reinforcing cool air arriving over the weekend.

Hurricane Irma will continue to dominate the headlines and will require our focus, locally, for potential impacts early next week.  While we’ve built rain into our forecast Tuesday into Wednesday, it’s crucial to note this is an incredibly tough forecast and will require a great deal of fine tuning as we move forward.  With that said, a blend of latest data and upper air analysis does suggest portions of the region (particularly eastern areas of the state) do stand a chance to get in on the action of Irma’s remnants Tuesday afternoon into Wednesday morning.  Otherwise, breezy easterly winds are expected for the entire region beginning Monday evening.  Stay tuned as we continue to analyze things.  Thoughts and prayers are certainly with residents and family along the Southeast coast from southern FL to the Carolinas, including the southern Appalachian region.  Speaking of, it should be noted Irma’s impacts will stretch well inland.  Irma is forecast to remain a major hurricane wherever she comes ashore (window of opportunity for landfall up from the southern tip of FL all the way up to the Carolina coastline) and her forward speed into the southern Appalachians will combine with the rugged terrain and high elevations to create significant problems inland given the most up-to-date forecast track.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall:  0.50″ – 1.00″ (highly dependent on where Irma’s remnants track)

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″
