Rare February thunderstorms push through region

From thundersnow to plain old thunder rain – all in the same week. Heavy rain, thunder and lightning is greeting commuters late into this morning’s rush hour.

The line should push through much of the region by 10-11 a.m. It has formed ahead of a weak cold front and area of spin at high altitudes intruding from the west.

10:00 a.m.: Most of the thunderstorm activity embedded within the line of showers moving through the region has weakened or died. Showers may continue in the region for the next 30-45 minutes. The back edge is now pushing into the zone from western Montgomery to western Prince William counties. This is the last update. Check out the view of the thunderstorms from space as they came through Fairfax and Montgomery County around 9 a.m.

9:45 a.m.: Showers and storms stretch from Annapolis to La Plata and King George County, Va. They continue to press east. The back edge of the rain showers is from roughly central Frederick County (Md.) to central Fauquier County (Va.). By late this morning, much of the region begins to dry out.

9:33 a.m.: The line is edging east of I-95 now and has weakened a bit. “Thunder in Wheaton was so strong a car alarm went off in the Wheaton mall parking lot as I walked by,” writes reader Jessica Lubetsky on Facebook. “Weird weather!”

9:25 a.m.: The line of storms has rapidly advanced to I-95, and stretches from Fredericksburg to Baltimore. By 9:45 to 10 a.m., it should reach Annapolis and stretch south into southern Maryland, where it will exit last.

9:06 a.m.: The heaviest activity has just passed through the area from Tysons Corner to Bethesda and Rockville and is pushing into eastern Montgomery County towards the Laurel area.
