MRX taking out any small chance for snow shower activity this weekend for southern Tn valley.. guess I can't blame them:
.LONG TERM...(Thursday through Tuesday)...The theme for Thursday
through Friday Night will be that the Tennessee Valley/southern
Appalachians will be between the northern stream storm track (over
the Great Lakes/upper Ohio Valley) and southern stream (from Texas
across the southeast United States). Plenty of high level clouds
will remain, but precipitation will be rather limited.
For Saturday, latest GFS and ECMWF agree with taking a fast moving
short-wave farther north across the Great Lakes and Ohio Valley and
just brushing southwest virginia and northeast Tennessee with light
precipitation. A mixture of snow and rain showers are expected.
Limited snow accumulations are possible across the higher
elevations, such as High Knob, especially Saturday night.
For Sunday and Monday, dry west to northwest flow aloft and
surface ridging will produce dry conditions and milder
temperatures for Monday.
For Monday night and Tuesday, another short-wave dives toward the
Ohio/Tennessee Valleys. Precipitation in for the form of snow is
possible, but the evolution of the system will likely change, so will
not get too specific.
--------for what it's worth, nrgjeff over at americanwx basically put the poo-poo on this 12 hours ago for the CHA area. Good call. He's a damn good met/poster btw, wish he posted over here too.
