Why So Cool In July? - 07/29/14

I hope everyone was able to get out and enjoy the beautiful weather we had today... highs topped off around 81 degrees in Nashville.  (the average for this time of year is 89).  Just for perspective, 75 degrees is the "coolest high" on record for this day, set back in 1891.  We were only 6 degrees away from it!  Plus tonight we could see a record low in Nashville and Crossville.  (Check out the graphic for details)

So, why is it so cool in July?  Why is it feeling more like early fall than mid summer?  It has to do with our weather pattern in the upper atmosphere.  Normally in the summer months the jet stream retreats to the north and hangs out around the Great Lakes.  But this week, we're seeing a jet stream pattern more typical in the winter time.  The jet stream has dipped into the deep south, allowing for cool, Canadian air to say hello.  (Of course, we're not facing winter-like temperatures because of the summer season and high sun angle).

Will it last?  Unfortunately, no.  But we'll still feel quite comfortable through the week.  Temperatures will climb to the upper 80s, but humidity will remain on the low side.  Enjoy!

SELFIE CRASH

ORIENT, Maine (AP) -- Texting and driving? Not safe. Driving while taking a selfie? Even more not safe. Police in Maine say a man crashed his car while taking a selfie with his passengers. Authorities say several people were hurt when 29-year-old Jordan Toner lost control of the vehicle he was driving with seven passengers. When he leaned over to take the selfie, his car ran off the road and hit a tree. He's been hit with a distracted driving summons.

DESTINY'S CHALLENGE

BOISE, Idaho (AP) -- Sheriff's deputies in Idaho are trying to find their destiny. That's Destiny as in the girl's name -- not their reason for being. Authorities have been interviewing more than a dozen girls named Destiny as they try to crack a vandalism case. It seems someone spray-painted a prom invitation on part of the Black Cliffs in southwest Idaho back in May. The message read: "Destiny, Prom?" If authorities can track down who was trying to woo Destiny, that person's destiny could be jail. The crime is punishable by up to six months behind bars and a fine of $1,000.

GRENADE BROUGHT TO POLICE STATION

SOUTH BURLINGTON, Vt. (AP) -- A grenade in hand -- was worth a lot of concern to police in South Burlington, Vermont. A woman found a hand grenade in her grandfather's belongings -- and decided to bring it to the police station. That got their attention. Police cleared the department and nearby buildings -- because they weren't sure if the grenade was live. In the end, the state bomb squad had to come in to deal with the grenade. As late as yesterday, authorities hadn't determined whether the grenade was dangerous or inactive. They are urging residents who find grenades or other potentially devices to leave them where they are -- and call the police.

TELESCOPE MISTAKEN FOR RIFLE

FARGO, N.D. (AP) -- They were hoping to check out some stars. But the first light they saw when trying to use their telescope -- was that from police officers who mistook their telescope for a rifle. Levi Joraanstad and Colin Waldera were setting up their telescope behind their apartment Monday when police flashed a bright light into their eyes and told them to freeze. The students couldn't see who was shining the light -- and thought it was a prank by other students. Despite the confusion, it turned out O.K. Police say the students were never in any danger -- and that police approached them because they'd rather be safe than sorry.
