RICHMOND, Va. (WTVR) – We’ve been looking for our next chance for rain beyond the 7 Day Forecast this week, and the medium range computer models have consistently shown precipitation in the November 13-14 time-frame. [Click here for full forecast]
But the data is now getting very interesting for Tuesday and Wednesday.
Both the European and GFS medium range computer models predict a very cold Canadian air mass will plunge into the central and eastern U.S.
At the same time, a strong upper-level trough is depicted to move into the Mid-Atlantic on Wednesday, triggering a coastal low formation east of Virginia and resulting in a mix of wintry precipitation for at least northern and western Virginia, and possibly central Virginia as well.
This event is still nearly a week away, so it’s likely that both the timing and strength of the atmospheric players involved will change.
We’ll continue to interpret the changes/trends/model biases over the next few days and update you here and on CBS 6.
If the snow falls, it could be our most significant November snowfall since 1987, when 4.5″ fell on November 11.
