Triple digits are on the front, uh, burner again today. A Heat Advisory runs from Noon-8pm. Heat Index values could reach 110 this afternoon.
An isolated shower/storm is possible early today from a frontal boundary that is Wandering Indiana. It went through as cool front yesterday.
Yesterday was a good example of the “Ring Of Fire” in action. Here’s a USA precipitation chart with a circular arc of rainfall Tuesday, relative to the big dome of hot high pressure in the mid to upper atmosphere. Yesterday’s precipitation positioning favored areas north and east of Indianapolis. There was .91″ of rain in Fort Wayne, .74″ in South Bend, and .47″ in Muncie. Just a lonely little “trace” at the Indianapolis Airport.
With this Ring…I promise you little rain hope today. The Ring, and center of heat, actually moves north again. A better chance comes tomorrow, as that upper air pattern relaxes enough to let another cool front through. The regime change may not be peaceful. There’s a slight risk of severe weather Thursday. Showers and storms could linger into some of Friday, but our world will dry out Friday evening (just like last weekend) and be much more comfortable this weekend. Start your engines!
Today’s 100+ high will be the 2nd occurrence just this week. It will be the 9th time this season. We’re getting close to number two!
One Hundred Degree Days :
–12 days in 1936
–10 days in 1934
Up until now the biggest recent summer for triple digits was 1988, when it happened five times.
Today will be the 38th 90+ day of the Summer of 2012 in Indianapolis. The average is 15 and the record is 58. I think we’re going for the gold medal this year. But don’t leave it outside, or it will melt.
