From GSPAs of 300 AM Sunday: Shortwave energy will carve out a deep troughacross the Northeast to Mid-Atlantic Wednesday into Thursday,which will bring a reinforcing dry cold front thru the forecastarea. The front may bring a round of stratocu along the TN borderand breezy conditions across the mountains Wednesday aftn intoWednesday night. This combined with temps still 10-15 deg belownormal may produce wind chills around -5F across the NorthernMountains thru early Thursday morning. Winds should subside andskies become clear Thursday, but highs will remain chilly.The latest guidance seems to be trending toward a distinct southernstream upper low in northwestern Mexico that interacts with adigging trough over the Great Plains. This will likely produce asfc wave near the Texas Coast late Thursday. This wave may advanceeast along/near the Gulf Coast and spread moisture across theSoutheast Friday into Friday night. The latest NBM already haslikely PoPs spreading into the forecast area Friday night. Thisprecip would likely fall into chilly air, which depending on thethermal profiles, may result in freezing rain, snow, or a wintrymix for our area. The 00z GFS shows mostly a RA/SN event, withaccumulating snow across nearly the entire forecast area Fridayaftn thru Friday night. The 00z ECMWF has trended toward the GFS,but is still more of a wintry mix setup with a warm nose punchinginto the area. For what it`s worth, the Canadian keeps the systemsuppressed and is mostly dry for our area. A little over a majorityof the ensemble members have measurable precip Friday-Friday night,with the mean sfc temps below freezing. So confidence is increasingon some type of wintry event late Friday or Saturday. PoPs wereheld in the chance range with a rain/snow fcst for now due to somuch uncertainty. This system will definitely bear watching.
