Going into the weekend: the month of May has been (duh!) much cooler than average in central Indiana. Friday brings the first highs in the 70s since May 4th for most of central Indiana. There’s only been one (!) day when the Indy high has gotten over 80 degrees this year, and that was 82 on April 27. It’s a much different story in Lafayette, where there have been 8 80+ days so far, even though the month of May has been cooler than average there also. There have been 6 80+ days in Muncie.
At the surface: high pressure moves across the state today, and then off to the east, helping to shift the winds from northerly to southerly. This chart of the upper air flow through the end of *next* weekend shows the strongest winds (the “jet stream”) migrating northward. This big ridge will finally open the door to late-Spring and Summer temperatures. There will be scattered showers and storms.
