LITTLE ROCK, Ark.- 1:10 AM, Sunday– The tornado watch that was previously in effect across portions of Arkansas has been allowed to expire. The tornado threat has diminished for tonight. While that may be the case, a strong thunderstorm producing gusty winds near 40 mph cannot be ruled out.
12:26 AM, Sunday– Due to some storms still showing brief rotation, the National Weather Service expanded the tornado watch to include a few more counties but also extended the time for the watch. It will remain in effect for the area highlighted above until 1 AM.
7:40 PM Update– The forecast remains on track with our cold front nearing NW Arkansas around 8 PM. A few strong to severe thunderstorms are still possible.
5:15 PM Update– The Storm Prediction Center out of Norman Oklahoma has issued a tornado watch for portions of northwest & north-central Arkansas until MIDNIGHT.
The watch was issued because this area has conditions favorable for tornadoes to be possible.
Remember, have multiple ways to receive severe weather information in case of power/internet outages.
The Arkansas Storm Team will be on standby this evening until this threat is over.
4:30 PM Update– We are keeping an eye on a fast-approaching low-pressure system and associated cold front that will be moving through the state this evening and overnight. This system will bring a chance for rain but also the opportunity for a couple of strong to severe thunderstorms.
The overall risk is low and conditional as well. What does that mean? Due to the fast nature of this system, there is a possibility that there will not be enough storm fuel and/or atmospheric lift necessary for thunderstorms to become strong to severe. If we don’t get enough storm fuel or have the support, we could just have showers and a few rumbles of thunder and that is all. If we do have enough fuel, then severe storms would be possible.
IF storms become severe, brief but strong wind gusts (50-60 MPH) would be the main concern.
While lower but not a zero threat, isolated hail up to one inch in diameter and a tornado or two cannot be ruled out. The main area of focus for these two threats would be northwest and north-central Arkansas.
The window for any strong to severe thunderstorms would reside between 7 pm and midnight. While there will be some activity before and after this time frame, ingredients will not be in place to aid in severe weather potential.
Drier and sunnier weather returns for Sunday.
