A cold front will approach the region on Friday, and this will provide a focus for some showers and thunderstorms across North and Central Texas through the weekend and into early next week.

It is July in Texas and it's hot. So you're probably thinking why is the National Weather Service telling us about the heat? Well, it's simple: heat kills. Know the signs of heat exhaustion versus heat stroke. Faint or dizzy with excessive sweating, that's heat exhaustion. Get to a cooler place and drink water. What if you or someone you know, is in the heat and suddenly stop sweating, get a throbbing headache and/or nausea? Well, these are signs of a Heat Stroke and this is an emergency situation. Your body is no longer able to cool off and if you don't get immediate care---it can be potentially fatal. If you're suffering from Heat Stroke, you should call 9-1-1 and then immediately take action to cool down. as you wait for help to arrive.

February 1899


A severe arctic outbreak consumed much of the country during the first half of February 1899.  Temperatures fell below 0°F in every state in the continental U.S.  Well over a century later, many all-time record lows remain from this event.  Ice on the Mississippi River flowed past New Orleans for the first time since 1784.

Between February 4 and February 13, there were only 8 hours with temperatures at or above freezing (on February 8) at the Weather Bureau office in downtown Fort Worth.  Despite northwest winds gusting over 30 mph, the mercury plummeted  to -8°F the morning of February 12.  The barometric pressure soared to 31.00".  Dallas dipped to -10°F, and Grapevine fell to -12°F.  Below are some other low temperatures recorded across North Texas on February 12, 1899.
