... Wind Advisory in effect until 6 PM CST this evening...
The National Weather Service in Huntsville has issued a Wind Advisory... which is in effect until 6 PM CST this evening.
* Winds... prevailing northwesterly winds around 25 mph are expected across all of northern Alabama and southern middle Tennessee through late this afternoon. In addition to this... winds will frequently gust to around 35 mph. Both sustained wind speeds and gusts will be higher in elevated terrain... primarily above 1250 feet.
* Impacts... winds of this magnitude will blow around any unsecured outdoor objects. Loose tree limbs may also be blown down... and driving will become difficult... especially for high profile vehicles.
Precautionary/preparedness actions...
A Wind Advisory means that sustained winds in excess of 25 mph... or gusts in excess of 35 mph are expected. Winds this strong can make driving difficult... especially for high profile vehicles. Use extra caution. In addition... ensure all loose outdoor objects remain secure... including patio furniture and trash cans.
A very cold Arctic air mass will continue to spread southeastward overnight... with low temperatures falling into the 15 to 20 degree range for most locations. The cold air temperatures... when combined with a persistent northwest wind around 10 mph... will result in wind chill values falling to between 8 and 12 degrees. In the higher terrain of northeast Alabama and southern middle Tennessee... temperatures will be colder and winds will be stronger... with wind chills approaching zero. Anyone venturing outdoors this evening and overnight is encouraged to prepare for dangerously low wind chills by dressing appropriately and limiting time spent outside.

* Impacts: a dry Arctic air mass will persist across northern Alabama on Sunday... resulting in critical fire weather conditions.
Precautionary/preparedness actions...
