It was starting to feel a little chilly around the edges at home this morning, and I confess I thought about turning on the heat to take the edge off. But I didn't. It was 37 degrees out on the Weatherdeck in Cockeysville, but still in the high 60s inside. Still no excuse for burning dollars and pumping more CO2 into the air.

That day is coming. I usually cave before Nov. 1. But the outlook is for some warming in Baltimore through the rest of the week, so I know I can get through the next week or so.

Still, while it was still quite mild near the bay and the ocean, the temperatures dropped sharply last night north and west of the city. BWI still hasn't recorded a night in the 30s this fall, but others have. Here's a sampling of some overnight lows:

BWI: 41 degrees

The Sun (downtown Baltimore):  47 degrees

Annapolis:  51 degrees

Ocean City:  50 degrees

Reagan National (DC): 50 degrees

Dulles International:  42 degrees

Hagerstown:  38 degrees

Martinsburg, WV:  36 degrees

Frederick:  34 degrees

York, PA:  33 degrees

Here's a NWS map with some more observations.

Tonight should be clear, a good opportunity to catch the International Space Station as it orbits from high over Lake Michigan and Central Virginia to the Outer Banks. The times are slightly different than those we published in the print editions on Sunday. That's because the Russians gave the ISS an orbital boost over the weekend, increasing its altitude and thereby putting it about a minute behind the previous flyby schedule.

Watch for a bright, star-like object to rise above the northwestern horizon at 8:01 p.m. It will climb about two thirds of the way up the southeastern sky by 8:04 p.m. It will pass high above the moon and Jupiter and very close to the bright star Altair in the Summer Triangle before vanishing abruptly into the Earth's shadow at 8:05 p.m.

As always, come back here after watching the ISS, leave a comment and share the experience.
