Tonight is the peak of the 2012 Lyrid meteor shower



April 22, 2012 Lyrids
The Lyrid meteors – April’s “shooting stars” – tend to be bright and often leave trails. About 10-20 meteors per hour at peak can be expected. Plus, the Lyrids are known for uncommon surges that can sometimes bring the rate up to 100 per hour. Those rare outbursts are not easy to predict, but they’re one of the reasons the tantalizing Lyrids are worth checking out. The radiant for this shower is in the constellation Lyra, which rises in the northeast at about 10 p.m. Fortunately, in 2012, the new moonguarantees a dark sky in the late night and morning hours, the best time to watch the Lyrid shower. As a general rule, the greatest number of Lyrid meteors fall in the dark hours before dawn. The optimal night will probably be from late night April 21 until dawn April 22, though the night before or after (April 21/22 and April 22/23) might also offer a sprinkling of Lyrid meteors. With no moon to obscure this year’s display, we are assured of dark skies for the 2012 Lyrid meteor shower!

Hail ravages North Texas, shuts down highway US 287


Three to four feet of hail is being reported on U.S. 287 near the Canadian River, according to the Potter County Sheriff's Office.
That's prompting the highway to be shut down by the Texas Department of Public Safety.
The Potter County Sheriff's Office also confirmed there were reports of buried motor vehicles prompting rescues.
DPS said its units are reporting low visibilities in the area. The main part of the hail is being reported four miles north of the Canadian River near the Fain Plant.
Officials said it is not known how long the road will be closed because parts of it are washed out.
