Notice to Navigators: Arkansas-White-Ouachita-Red Rivers

Severe Weather Risk Today and Tuesday;
Winter Weather Risk Wed-Thurs

Good morning Shreveport partners,

There are still a couple of chances for severe thunderstorms across portions of the Four State Region today through Tuesday evening. There will also be a chance for wintry precipitation across Southeast Oklahoma on Wednesday and into Thursday morning.

This Evening through the Overnight Hours

  • Slight Risk for severe storms across Southeast Oklahoma and adjacent portions of extreme Southwest Arkansas, and extreme Northeast Texas.
  • Damaging winds, large hail, and isolated tornadoes will be possible.

Tuesday and Tuesday Evening

  • There will be a Marginal Risk for severe storms over much of Louisiana and Southern Arkansas, but chances should be greater farther east.
  • Damaging winds and large hail will be the primary threats. The tornado threat should be very low, but an isolated tornado cannot be ruled out.

Wednesday into Thursday Morning

  • What & Where
    • Freezing rain will be possible in Southeast Oklahoma, possibly into adjacent portions of extreme Southwest Arkansas.
  • Impacts
    • Ice accumulations of a trace to possibly a few hundredths of an inch are possible.
  • The winter weather forecast is extremely uncertain as cold air damming from the Ouachitas will prevent much of the cold air from moving into the area.

 

Additional updates will be emailed as staffing/time permits.  Please reference the additional resources below for more information.
