The weather pattern continues to get very interesting toward the end of this week. We're finally going to see a break from the wet weather by Thursday afternoon; however, a fast moving wave of low pressure will quickly take over by the weekend, creating a winter weather possibility late Friday night.



The map above shows 250 mb winds for Friday night. The strong jetstreak colored in purple will create an area of low pressure at the surface across southern Texas Friday night. Moisture will stream north from the gulf ahead of the low, and in addition to the moisture, the surface low will also pull in cold air from the north.




Look at the cold air above. This is the GFS' prediction by midnight Friday. This cold air has the potential to change the rain over to snow late Friday night. Obviously, we're still several days out, but if this scenario comes true, northwest Arkansas could receive several inches of snowfall. Forecasted QPF amounts would translate into 2 to 4 inches of snow. This is very early, and I want to see more conformation from the NAM before I predict totals. The River valley could also see accumulations, but it will depend on the cold air, so stay tuned!
