DISCUSSION
Key message 1: Spotty light snow showers or flurries will taper off by evening.
Strong northwest flow and copious low level will keep clouds across the mountains into the evening. Some of the clouds will continue to spill out across the foothills and Piedmont. Spotty light snow showers or flurries should taper off by evening with little to no additional accumulations. Gusty winds taper off by evening as well.
Key message 2: Cold temperatures and dry conditions continue into Monday. A warming trend returns through the week with dry conditions lingering.
An upper trough over the area moves east on Tuesday as an upper ridge settles over the area blocking any weather systems from moving into the southeast. At the surface, high pressure settles over the area by Tuesday then remains in place through the end of the period. Low end gusty winds continue on Sunday, especially across the mountains before the high builds in. Below normal temps continue through Monday, then a steady warming trend takes place as the air mass modifies. Temps end up 5 to 10 degrees below normal by the end of the week.
AVIATION /00Z SUNDAY THROUGH THURSDAY/
At KCLT and elsewhere: VFR conditions will prevail through the forecast period. Lingering stratocu across the mountains will stick around through the evening and overnight periods. Stratocu over KAVL will linger over the next few hours before dissipating, so kept a low-VFR cig mention in the TAF through around 06Z. Most of any gusts have subsided across the area, with the exception of KAVL, where low end gusts stick around through this evening before lowering. North to northwest winds continue through tonight and pick up out of the north to northeast on Sunday, with low end gusts returning to KAVL by late Sunday morning.
Outlook: VFR conditions are expected to continue through at least the middle of next week.
