December 9, 2018: Forecast

Diego was a major winter storm that developed off the coast of California the week of December 3rd.  The storm traveled across the southern tier of the country and redeveloped along the Gulf Coast on December 8th. By Sunday, it regenerated off the Carolina coast, pushing copious amounts of moisture and wintry precipitation into North Carolina and Virginia. It’s track closely followed a “Miller A” type setup for a winter storm.

In retrospect, the majority of folks forecasting this event underestimated the amount of snow Central Virginia would receive. Days before the event, snow totals were quite low. The NWS out of Wakefield only significantly increased snow totals on the morning of the 9th. A progression of the snowfall forecast is shown below:

NWS Forecast – Day of Event

A major storm in now on it’s way with the expected development of a coastal low off the Carolina coast later today, impacting the area from Friday morning into Saturday night. The system is expected to bring period of heavy snow, sleet and possibly freezing rain to Richmond. Models latched on to a storm threat since last weekend (January 16th-17th) and have continually shown a winter storm that will impact most of Virginia and a good portion of the Mid-Atlantic, Ohio Valley and North East. Snow totals to the north and west of Richmond are expected to exceed 2′ in spots. The storm is taking on characteristics (intensity and snowfall) of the Snowmaggedon (2/2010) and 96′ Blizzard. Snow totals in Richmond will be highly dependent on the amount of sleet that falls Saturday night. Models have varied snow from 5-6″ upwards of 20-24″.
