Severe Weather Update

* The SPC has upgraded to a HIGH risk for parts of western Mississippi. High risks are reserved for the really bad days, so they are anticipating an outbreak of severe weather and tornadoes out there. Here's the outlook:

SPC Day 1 Outlook


* While we will definitely see some severe thunderstorms, I really believe the highest threat of tornadoes will be west of most of our viewing area - mainly along and west of Highway 35.

* The thing preventing us from seeing a major outbreak is the dry and stable air moving in from Alabama. Dewpoints in central Alabama are in the 40's and 50's, which is too dry to support tornadic supercells. This air will move west through the day. Exactly how far west it moves will be critical in determining the magnitude of the severe weather threat here.

* Timing: I think we'll see the event get underway in our area between 4-8 pm, lasting until 1-2 am. These times are not exact, so be on your toes throughout the remainder of the day and into the overnight hours. Today is a great day to know you and your family will hear warnings because you have a NOAA weather radio!

* Threats: A few isolated tornadoes, mainly west. Also some large hail...But I believe damaging straight-line winds will be a big factor today as well.

* Heading to work...
