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 /18Z SATURDAY THROUGH THURSDAY/

At KCLT and elsewhere: VFR stratocu, with cigs at KAVL, will dissipate by evening, but can't rule out some lingering stratocu across the mountains. Mostly clear skies Sunday, but some cirrus may move in. Low end gusty N to NW wind, stronger gusts at KAVL, become light N wind by evening. Light N to NE wind Sunday, with low end gusts returning to KAVL.

Outlook: VFR conditions are expected to continue through at least the middle of next week.
