1/05 Update on 2 potential winter weather systems

Up to an inch of snow is possible in the triangle region as a weak surface features] moves into the western Atlantic through the deep south. Scattered snow showers, associated with this system's deformation zone, are likely and up to an inch of snow is possible. qpf of about .1 on both the NAM and GFS with decent ratios could cause some problems for rush hour commute. Expect the heaviest snow to fall between 5 AM and 9 AM in the triangle. The precip will start as light rain before mixing with and likely changing to all snow. Surface temps will likely stay above freezing through the even which should help to dampen accumulation. Therefore while an inch of snow is possible, it is quite unlikely that more than a dusting will occur. Also, warming just above the surface is likely due to a weak low pressure forming on the Lee side of the Apps in response to the upper level feature. This could keep precip mixed throughout the event.

A winter weather advisory still may be issued tonight by the NWS.


The next system will arrive in the 6-7 day period. This system has the potential to produce signficant snowfall for the triangle. But with it being this far out it is only worth keeping an eye on at this time. Very cold air will follow behind this storm system.
