3 a.m. update: The fast-moving line of storms exited eastern Virginia around 2:30 a.m. The severe threat is over, and the thunderstorm watch has been cancelled. Scattered showers and gusty winds will be possible through around 7 a.m.
RICHMOND, Va. -- The Richmond metro and southwest has been upgraded from marginal to a slight severe weather risk as a strong cold front will pass through after midnight Sunday.
The strongest dynamics with this system will track north of Virginia, but enough ingredients will be in place overnight for the storms to be strong to possibly severe.
Wind gusts will increase tonight to over 30 mph. Winds a bit above the surface will be a lot stronger, and a few of these showers and storms may transfer some of those stronger gusts down to ground level. The strong gusts will be our primary severe threat.
Storms will produce heavy downpours, but the storms will be moving very quickly and won't linger very long.
After daybreak, clouds will decrease from west to east, and Sunday afternoon will be partly to mostly sunny.
It will be a little cooler Monday into Tuesday, but a bigger drop in temperatures will arrive at the end of the week.
The CBS 6 Weather Authority team will be monitoring the storms all night. Updates will be available on CBS 6 and wtvr.com as needed.
