Mountain Area Forecast ( April 7-9 )
ALERT For Accumulating Snow Overnight Into Friday Morning At Elevations Above 2000 Feet – Significant Accumulations Are Expected At The Upper Elevations With Lesser Amounts Below 3000 Feet
*Snow Depth Forecast Into Friday – April 7
Below 2000 Feet: Little to no accumulation
2000 to 3000 Feet: Dusting to 2″
Above 3000 Feet: 2″ to 8″+
*The greatest snow amounts will occur at the highest elevations. Forecast error potential ( +/- ) 1″ on the listed elevation ranges to imply 1″ to 3″ possible at 3000 feet elevation.
The level of accumulating snow ( 1-2″ at the summit level of the High Knob Massif as of 8:00 PM Thursday ) will drop downward toward 2000-2500 feet by Friday morning ( on the upslope side of the mountains ). Conditions will begin to improve after 11:00 AM Friday at all elevations ( but will remain windy & cold ).
Rain and snow, or a rain-snow-sleet mixture is expected to occur at elevations below 2500 to 2000 feet, with little to no accumulations below 1500-2000 feet in elevation.
Overnight Into Mid-Morning Friday
Rain changing to wet snow above 2000 feet. Sleet possible. Sticking snow levels dropping toward 2000 to 2500 feet by morning. Rain showers or a mix continuing at elevations below 1500-2000 feet. Snow heavy at times, especially at higher elevations. Windy. Cold. Winds WNW-NW at 15-30 mph, with higher gusts. Temperatures varying from upper 20s to middle 30s to the upper 10s to middle 20s at highest elevations. Wind chill factors varying from 10s to lower 20s to the single digits and 10s ( except near to below zero in stronger gusts at high elevations in the High Knob Massif ). Blowing and drifting snow at the highest elevations.
Partly cloudy. Windy & unseasonably cold. Winds WNW-NW at 10-20 mph, with higher gusts. Temperatures varying from 30s in upper elevations to the 40s. Wind chills in the 20s and 30s, except 10s in gusts at highest elevations.
Friday Night Into Saturday Morning
Mostly clear. Cold. Winds diminishing in deeper valleys. NW winds 5 to 15 mph, with higher gusts, on mid-upper elevation mountain ridges. Temperatures in the 20s to lower 30s, except 10s within upper elevation valleys that can decouple from boundary layer flow ( i.e., winds calm with drainage flow development ).
Partly sunny ( high clouds possible ). Milder. Light winds shifting W-SW at generally less than 10 mph. Temps from 40s in upper elevations to the mid-upper 50s.
Saturday Night Into Sunday Morning
Mostly clear. Large vertical temperature spread developing between colder valleys and milder ridges. Light southerly winds at less than 10 mph on most mountain ridges. Temps varying from 20s to lower 30s in valleys to 40s on exposed mountain ridges-plateaus ( 10s to lower 20s in colder high valleys of the High Knob Massif ).
