Just back from a Jacksonville, Fla. wedding, where the heat, the humidity and the mosquitoes make one wonder why anyone lives down there in the summer. Arrived at BWI last night to find the temperature 20 degrees cooler thanks to this nice Canadian air mass. Opened the house up before we hit the sack, and woke up reaching for the blankets.

It was 56 degrees on the WeatherDeck in Cockeysville this morning. The instruments here at The Sun fell to 68 degrees by 6 a.m. The official low, at BWI-Marshall, was 58 degrees, in the pre-dawn hours. That was just 3 degrees shy of the record low for the date for Baltimore - 55 degrees, set on this date in 1985.

In fairness to the Floridians, the same cool air that has made life so pleasant here for the last couple of days, did finally make it all the way to north Florida yesterday. The sky cleared and, except for the remarkably strong sun at that latitude, it was much more tolerable - in the 80s, and much drier. A bit of shade and something tall and cool made it just about perfect.

The rest of the week for us looks unusually mild for this time of year, with highs only in the mid-80s and comfortable humidity. The normal high for this time of year at BWI is 88 degrees. The chance for a thundershower or two increase as the week wears on. Here's the official forecast.

We can sure use the rain.
