Afternoon temperature made a jump Tuesday climbing well into the middle and upper 70s.   The official high reached 78° in Indianapolis, the average high for September 15th.

Overnight temperatures will only settle near 60° early Wednesday morning - very mild for early October.  The average low this time of the year is 48°.

The south breeze continues Wednesday and area temperature will respond, forecasting to surpass the 80° mark.  80s in October are hard to come by, we average only 2 80 degree days from October 1st to the end of the year.

Thursday will be even warmer, reaching the low to mid 80s.  Temperatures are expected to be as much as 12 to 16 degrees above normal for much of the eastern U.S.



Warmer and soon more humid air develop Wednesday and combined with a weakening front, could bring a few showers into the area Wednesday.  Spotty showers and possibly a thundershower cannot be riled out bu coverage lloks minimal and at best isolated.




October temperature signals are for above normal and the latest 8 to 14 day outlook shows much of the nation with  a high probability of  warmer than average temperatures as well.

A few cool downs will occur but look rather brief through the next 3 weeks of the month.  While days shorten and nights lengthen the cooler air will win out.  However, the jet stream will exhibit a more west to east, "zonal" flow which is a warm one.

An interesting note, 12 of the past 13 months have averaged above normal for Indianapolis.

There are hints of a strong/large surge of cool air buckle in the jet stream off long range models later in the month.  but for now it looks like October will be the 13th month out of 14 above normal.



A westerly jog to the powerful Category 4 hurricane Matthew continues to be evident in latest computer model forecast tracks.  Additional hurricane watches and warnings are now hoisted along the east coast of Florida and will likely be extended well into the Carolina's.

11 pm UPDATE:

Many watches in Florida have been upgraded to hurricane warnings as Mathew exits the northeast coast of Cuba.  Winds remain strong at 130 mph as Category 4 storm.





Matthew is projected to make landfall and skirt along the coast of Florida by First afternoon but uncertainly still continues.  The trusted EURO model brings Mathew into southeast Florida north of Palm Beach then scrapes the coastline into southeast Georgia.  By no means a final take on the storm track, preparations are underway in the the southeast for Matthew's arrival.  Per teh National Hurricane Center, their track has been adjusted slightly west indicating a "major" hurricane off coast of Florida 8 pm near Jacksonville.
