Jason Simpson is WHNT News 19’s Chief Meteorologist. He joined our team in January 2012.

Raised in Holly Pond, Jason is no stranger to the Tennessee Valley. Prior to joining WHNT News 19, he served as the morning meteorologist at ABC 33/40 in Birmingham, working alongside longtime Chief Meteorologist James Spann from 2004 to 2011. Simpson actually began his career while still in college, interning at ABC 33/40 as well. After college, he worked at WTOK-TV in Meridian, Mississippi, where he was Chief Meteorologist.

Jason was awarded the American Meteorological Society’s Certified Broadcast Meteorologist Seal for excellence in television weather in 2007. Simpson graduated from Mississippi State University with a degree in Broadcast Meteorology.

Jason has covered many weather events from hurricanes to tornadoes and blizzards. Jason was on the air April 27, 2011 and saw firsthand the magnitude of the destruction in different parts of Alabama. After the storm he took action, volunteering in devastated areas to help people rebuild and where he couldn’t go, he sent supplies.

A staunch advocate for science education in the classroom, Jason has been instrumental in building curriculum for elementary and middle school science classes through the “ABC’s of Weather” series that he produced for the Alabama Math Science and Technology Initiative.

Jason and his wife Lacey have two beautiful children: Walt (born in 2011) and Shelby (born in 2013).

    The 58ºF “Rule”

    Update on Wednesday at 11:41 AM: The Jefferson County tornado will be given a preliminary rating of EF-2. If you have watched any of my Facebook live streams lately, I’ve mentioned this rough rule based on some research done several years ago. Brian Peters, formerly the Warning Coordination Meteorologist at the National Weather Service in Birmingham, gathered the data showing that Alabama had never recorded a tornado with a dewpoint below 58ºF. I call it a rough rule because it […]

    Storms on Tuesday: what to expect

    As of Tuesday afternoon, the risk of severe thunderstorms is diminishing, though a few wind gusts above 40 mph are not out of the question, especially in northeastern Alabama. The limiting factor today is the lack of high-energy, moisture-rich low-level air, and it likely plays a role in reducing the strength of storms. The dewpoint likely stays at or below 59ºF as storms move into the Tennessee Valley region; we have no recorded tornadoes with dewpoints below 58ºF in the state of Alabama. […]

    A chance of rain every day next week

    There are 120 hours in a five-day period.  It will not rain for 120-straight hours next week, but there is a chance of rain on at least a few hours out of each day Monday through Friday. A weak cool front brings some light, scattered rain to the Tennessee Valley Monday; the odds of getting measurable rain (that’s more than 0.01″) stand at 30% for the first half of the day.  After that, rain moves out Monday afternoon and evening, but more […]

    Get the latest on tonight’s severe weather potential

    Rain, wind and storms are likely tonight.  This post may become outdated as the situation rapidly changes over the next few hours.  See our LIVE BLOG here on WHNT.com for the latest specific information about tonight’s severe weather threat.  The broad overview is still good; however, the most updated information will be on the live blog. What to expect:  The strongest storms form where instability and wind shear (fuel and dynamics) exist; that’s clearly south of the Tennessee Valley.  This round […]

    Windy weather here and beyond

    It’s hard to call it a “wind storm” since it wasn’t all that stormy, but it sure was windy over a large part of the Eastern United States Friday! Peak wind gusts around the Tennessee Valley paled in comparison to the high winds to our north. Just north into Middle Tennessee, it was much more significant. Windy out there! As of 11am, peak wind gusts have been 49 mph at #Clarksville & 45 mph at #Nashville! #tnwx pic.twitter.com/ZHfYa7dmC8 — NWS Nashville […]

    Heritage Elementary Sixth Grade Kidcam!

    I always love my annual trip to Heritage Elementary in Madison!  Mrs. Beth Clemmons and her colleagues let me come spend some time with the Sixth Grade every year, and I am always impressed with this group.  They ask thought-provoking questions, play along when it’s time to have fun and listen intently when it’s time to get serious. There are some very intelligent students in this crew, and it will be fun to watch them grow and succeed over the […]

    Close to 70ºF before you know it!

    The past two days have been no fun. It’s been chilly and wet. Some spots already have more than three inches of rain, and there’s more to come through Tuesday evening: Refresh this page for the latest radar image: Once the rain moves out tonight, we get a little temperature set-back. Highs only reach the middle and upper forties on Wednesday afternoon – thanks mostly to the clouds that just won’t want to move out very quickly. A few hours […]

    Check out this “Ice Spike” in Guntersville

    Sometimes cold weather causes strange things to happen.  Things like frost flowers and “ice spikes” happen more often than we know in this area, but they do seem unusual when they happen in your own backyard!  Check out the “ice spike” that formed in Theresa Kelley’s Guntersville bird bath Thursday morning when temperatures plunged into the mid-20s. Spikes like this are caused by upward-freezing water.  The following partial explanation and diagram are taken from “Ice Spike Formation Induced by Dendritic Ice Sheets” by Miles […]

    A cold wind and some occasional snow Monday afternoon through Tuesday

    A big blast of cold weather comes in two waves: one on Monday, the second Monday night.  Some showers move in ahead of the first cold front Monday morning, so an umbrella won’t be a bad accessory to have on hand.  Temperatures drop into the 30s around sunrise, but there is no risk of any travel hazards beyond wet roads early in the day. By Monday afternoon, another wave of showers moves in and gradually mixes with then changes to […]

    Streaks in the sky on Friday

    Some days our perfectly clear, blue sky shows some white, smoky-looking lines that follow aircraft.  These are “contrails,” or more technically: cirrus aviaticus.  They are clouds that develop in high altitudes as water vapor crystallizes around small exhaust particles (it makes small ice crystals) up around 20,000 to 30,000 feet. I noticed them showing up by late morning, and Ramona Edwards sent a photo of several of them clustered over the Marshall County sky on Friday around midday. She writes: “…there were […]
