Prolonged Period Without Heavy AC Use Ahead?

These butterflies were not bothered a bit by the electronic shutter sounds of digital cameras the other day. I was not the only one trying to capture the striking colors. Sandie's niece is turning into quite a talented photographer, and it was fun to compare pictures later in the day.
Early morning thunderstorms have been flying in from the west, but losing some of their punch as they head east. If you were watching Paul Barys yesterday afternoon, you saw a similar thing happening then. A lot of lightning across western Tennessee down into Mississippi, weakening as they ran into more stable air here. So rain and storms this morning should keep things from getting very stormy here when the next round arrives this evening and tonight. Certainly frequent lightning, some wind and hail possible, but the worst of this stays west of us.
Two more large thunderstorm complexes are behind the first. One over Arkansas, the other in central Oklahoma. And in the driver's seat is a large upper low over Minnesota which will be the long term weather maker to watch. Looks like it will cut-off from the main flow and spin it's heels around the Great Lakes for several days. So a northwest flow aloft will take over heading into the weekend.
Right now it looks like showers end fairly early tomorrow morning and it turns windy tomorrow afternoon. Highs Thursday afternoon will top out around 73.
Chilly Friday morning with lows in the upper 40s. Partly cloudy and breezy Friday afternoon with highs around 72.
The weekend time frame has to include some slight shower chances both days. I think with northwest flow above the ground, chilly air aloft and any small scale disturbances we could trigger a late morning or afternoon shower either day. But it looks like Mother's Day there would be a better chance for a few more of these showers popping up.
An eastern trough in the jet is favored in the pattern for the next two weeks. And while it looks like things get warm around the 20th, the Climate Prediction Center keeps most of the U.S. east of the Mississippi River cooler than average through May 23rd. Wow if that pans out! Could a prolonged period without heavy air conditioning be in the cards?
