Freeze warning for Allegany

The National Weather Service has posted a freeze warning for tonight in Cumberland and other portions of Allegany County. Temperatures out west could dip as low as 30 degrees tonight as cold air continues to stream in from the Great Lakes and Canada, and clear skies allow plenty of the day's solar energy to radiate back out into space.

Of course, that also makes it a great night for stargazing. The big show this month remains Jupiter, brilliant in the southeast in the evening and just a couple of weeks past opposition - its closest and brightest apparition of the year. Binoculars should reveal as many as four of its moons, lined up on either side of the big planet.

If you get lucky while you're outside tonight, maybe you'll spot a fireball like this one. It was photographed from El Paso, Texas, on May 4.
