The NAM: Colder than the other models however has trended warmer throughout the day. The NAM has the closed upper low moving very slower to the east. During the time, southwest flow will be moving The Natural State. Due to the lack of the snowpack in the Ohio Valley, this will lead to a period of rain/sleet for central and south Arkansas with the mix pushed to northwest Arkansas. A transition would occur Late Wednesday into Thursday for most of the state to sleet/snow.
The GFS (American Model): Slower/Warmer Model trend. It has the upper low closing off however with little to no snow in the ohio valley, This will lead to WAA (Warm Air Advection) to win out and produce rain vs wintry weather throughout the day on Wednesday. As we move into Thursday night, the upper low will move over the northern half of the state, changing the rain to snow before ending on Friday.
The GFS-FV3: Semi-Slower but warmer model trend. It has the same as the (current) GFS. Rain throughout Wednesday into Thursday with a transition to snow across north Arkansas occuring Thursday morning before ending.
The EURO: Similar to the GFS, slower/warmer for much of the state. It brings the same setup that brings snow to the northwest half of Arkansas.
