• 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)

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″
