The National Weather Service in Amarillo, TX has just issued a Winter Weather Advisory, as seen in blue on the map above, until 1 PM on Thursday for the western half of the Texas Panhandle. This advisory does include Amarillo. The potential for heavier snow amounts then earlier anticipated has required an advisory be issued. Snow accumulations in the advisory area will likely average 1 to 2 inches, with a few folks seeing up to 3 niches. Due to the warm ground temperatures, long term impacts should be negligible and snow will likely melt fairly quickly after it stops falling. However, heavier bursts of snow will likely cause some travel issues, so please use caution. Here’s the advisory text from the NWS Amarillo.

This graphic shows the estimated rainfall amounts that will fall over the next three days from the Hydrometerlogical Prediction Center, and is valid through Saturday Morning. This isn’t going to be a major rainfall event, but it looks like the folks in Northwest Texas and counties along the Red River are going to be the winners with this rain event. Rain should begin later tonight behind a strong cold front that will be moving south across northern parts of Texas. Behind this front, temperatures will fall into the upper 50′s to lower 60′s this afternoon with gusty north winds. As an atmospheric disturbance scrapes the region later tonight, steady rainfall should begin to develop. Since most of this precipitation will be behind the cold front, instability will be minimal and severe weather is not anticipated. Rainfall will likely continue through the day on Thursday in most locations.

This graphic comes from the 12Z NAM and is the outputted temperatures at 4 PM on Thursday. South of the cold front, temperatures will remain close to 80 degrees with south winds. North of the front and where rain is falling, temperatures will remain at or just below 50 degrees. No doubt that tomorrow will be a dreary, cold day. Still, I can’t help but look forward to it after the summer we experienced.
