(This image shows simulated radar at 4am Thursday with storms developing along and north of a frontal boundary in Northwest Arkansas)
A stationary front continues to linger around the area this afternoon but will slowly move north late today as a ridge of high pressure builds in over Texas.
The greatest chance for storms will occur when the low level jet strengthens after 10pm and into the early morning hours. The storms will be elevated and based above the surface which lowers the risk for gusty winds, tornadoes, and hail. However. lightning will once again be vivid with any thunderstorms that develop and they could produce torrential rainfall.
The boundary will be in Missouri by Friday afternoon and the rain chances will be all but gone into the weekend.
In summary:
- More thunderstorms tonight
- Time: 11pm – 4am
- NWA more favored than Fort Smith
- Frequent lightning, low severe risk
