Sure. Why not? Warm body of water, Arctic air. Wont be the same degree as a big Lake or Ocean but sure can develop.
Here's from Louisiana November 2014.
"" Down our way this past weekend, the same arctic air mass blowing along with 20 plus mph winds brought a rare occurrence to Shreveport/Bossier City called "River Effect Snow". The same situation like what happened in Buffalo developed on a much smaller scale in the river cities. Very cold arctic air blowing across a relatively warm Red River created an unstable situation causing light snow showers. Shreveport National Weather Service Meteorologist Jason Hansford describes the rare phenomenon last Saturday on Facebook (See Figure 4):
So Facebook has been lighting up today b/c a few snow flurries actually fell early this morning in Eastern Shreveport and part of Bossier City. Here is a radar image I captured at 631am this morning, with several surface observations overlayed. This was a rare and unusual event, where the snow flurries were actually induced from the Red River. You can actually see the path of the river through the higher reflectivities on radar, with the Shreveport Downtown Airport recording "Light Snow" between 545-1030am. Much like Lake Effect Snow, where snow can develop over the warmer waters (which are a source of lift) and move with the winds downstream, this was what I would call "River Effect Snow", where the light snow developed over the warmer waters of the Red River, and moved west northwest over areas mainly near/just west of the river. Since temperatures were above freezing, the vertical lift weak, and the air just above the ground very dry, no snow accumulation occurred"
