Along with the hurricane season, this is the first day of the meteorological summer, and the weather has been right from central casting: hot, muggy and unsettled.

It hit 93 on Memorial Day, and it may head back to 90 on Thursday, but after that the temperatures should become more pleasant, and the air-conditioning hum more muted.

According to the government's June 5 to June 11 outlook, the odds favor below-normal temperatures around here and through much of the northern United States as a cooling upper-level area of low pressure settles over the Northeast.

As for the rest of the summer, the government's Climate Prediction Center isn't making a call on temperature for the Philadelphia area.

Both Accu-Weather Inc., in State College, and WSI Corp., in Massachusetts, are saying June will be warmer than normal in Philly, with summer heat peaking in August.
