UPDATE 10:15 AM: Most precipitation has ended in Southwest Virginia. As has become the calling card of this winter, frozen precipitation reports were spotty … a little more snow west of Roanoke and in higher elevations, very little sleet or snow in the Roanoke Valley (I saw not a single pellet or flake), but some reports of snow, briefly heavy at times, to the south and east of Roanoke at similar or lower elevations. A cold front passing later today will reinforce cold air for Wednesday, with upper teens and 20s lows, upper 30s to 40s highs. Then, on Thursday night and early Friday, we move on to our next borderline winter precipitation setup. END UPDATE
Winter weather advisory remains in effect this morning, Roanoke Valley, Blue Ridge and westward — CANCELLED
Surface temperatures are well above freezing — upper 30s and low 40s, having risen some overnight in many areas on southerly winds and underneath cloud cover — in the Roanoke and New River valleys as precipitation approaches from the west this morning. Cold/dry air aloft may still be sufficient to induce evaporational cooling for a period of sleet and/or snow as precipitation begins, with temperatures briefly falling into the low to mid 30s, before rising again during the morning. Accumulations should be slushy and light — less than an inch in most locations, locally as much as 2 in some higher elevations — but there could be some travel difficulties, especially in higher elevations and on bridges and overpasses. Most of the precipitation should be over by late morning with temperatures rising well into the 40s and some 50s this afternoon.
