Near Record Winter Weather

January 3, 2008 at 10:47 pm | Posted in Uncategorized | Leave a comment

Wednesday morning, our temperature dipped to 23 degrees, the coldest at DFW so far this winter. And it was even colder in the northern and western counties of North Texas. It dropped to 18 in McKinney, 17 in Denton and Mineral Wells, 16 in Bridgeport and 12 in Graham!

But that wasn’t the only unusual weather that occurred Wednesday. At 11:15 yesterday morning, the pressure reached 30.97″. the 2nd highest I remember ever seeing around here. The all-time record is 31.06″, set in December 1983. That was in the middle of a historic cold wave, when we were below freezing for 12 consecutive days and nights!

Usually, the pressure is lowest in storms like hurricanes. And the pressure is highest under big arctic outbreaks in winter. Here are some links with more information on atmospheric pressure:
