Tornado Total Now Up To 8

As National Weather Service survey teams continue to assess Saturday's storm damage in Virginia, our official tornado tally rises. As of Tuesday morning, there are now eight confirmed tornadoes in Virginia from Saturday, April 16, with two more suspect areas in Lunenburg County (near Victoria and also around Rehoboth) that have yet to be surveyed. This graphics lists our six strongest tornadoes of the eight from Saturday:
The National Weather Service in Wakefield continued to survey the damage Tuesday in eastern Virginia from Surry through Mathews Counties and into Middlesex County from Saturday's tornadoes. They have now released an upgrade to EF3 (136-165 mph estimated wind speeds) for the tornado that tracked from just south of the Surry Nuclear Power Plant northeast into Mathews County. This tornado was initially surveyed as a strong EF2, pending further investigation, which was completed Tuesday. The NWS survey team estimates this EF3 tornado touched down just south of the Surry Nuclear Power Plant at 6:45 PM and caused a nearly continuous damage path all the way to Southwestern Mathews County at 7:20 PM. This puts the tornado on the ground for approximately 30 miles! The width of the tornado ranged from around 200 yards to as much as a half-mile wide in Gloucester County. More than 200 homes were damaged, with numerous trees either downed or sheared off. Two people were killed as a result of this tornado, with 24 others injured.

The damage farther northeast around Deltaville in Middlesex County was deemed to be from a newly formed tornado rated EF2 (111-135 mph estimated wind speeds) from that same supercell thunderstorm. Surveyors Tuesday estimate an EF2 tornado touched down at 7:25 PM at Fishing Bay in Southeastern Middlesex County, moved northeast through Deltaville, then dissipated at 7:40 PM over the Rappahannock River. This tornado was as wide as a quarter-mile and was on the ground for about 3 miles, damaging 95 homes (in Deltaville) and downing or shearing off numerous trees in the area. No injuries or deaths occurred from this tornado.

The National Weather Service in D.C. confirmed Monday evening an EF-0 tornado 2 miles west of Leesburg, VA in Loudon County at 7:14 PM Saturday. A few trees were uprooted and a street sign post was pulled from the ground and snapped. Several other snapped tree limbs occurred as a result of this tornado.

The National Weather Service in Blacksburg surveyed damage Sunday and confirmed two tornadoes from Saturday.

An EF-0 (85 mph winds) moved through Rockbridge County around 2:03 PM Saturday. The path length was 1.3 miles and the width was around 100 yards. It produced minor damage to a few homes and barns and knocked down several trees.

The other tornado was confirmed in Halifax County. An EF-2 (111-135 mph winds) moved through Virgilina and destroyed numerous homes. There were a few minor injuries, but no fatalities.

Update - At Least Four Confirmed Tornadoes In Virginia On Saturday

Severe thunderstorms raced across the area Saturday afternoon and produced widespread damage. At one point, storms were moving 55 to 70 mph. There are now at least four confirmed tornadoes in Virginia.

One tornado touched down in Augusta County (EF-1 with max winds 95 mph) and knocked down several trees and destroyed numerous barns.

A tornado is now confirmed in Dinwiddie County with a path around 8 miles long and 300 yards wide. Many homes were damaged along the path of this tornado.

Two more tornadoes were confirmed in Isle Of Wight and Gloucester counties. There was extensive damage in Gloucester with three fatalities. National Weather Service is going to survey the damage more today to see the strength of the tornado.

There was also wind damage in Halifax County where eight homes were destroyed with four minor injuries. National Weather Service will survey the damage today to see if this was from a tornado.

At one point, the Tri-Cities area was under a Tornado Warning, however, with the exception to a few toppled tress, there were no reports of major damage.

There were a few reports of hail in Crewe and Powhatan. We received pictures of quarter to golfball-sized hail.

Here are some maps which show all of the storm reports from today. The "W" represents wind damage, "H" is hail and "T" is tornado. North Carolina was hit hardest today, where there were nearly 100 tornado reports!

Risk for Severe Storms Saturday

An intensifying low pressure storm system in the Four Corners region of the western U.S. this Thursday morning is going to track through the southern Plains today, then move northeast toward the Great Lakes at the end of this week. Along the way, it should produce rounds of severe weather. This storm system will impact the Commonwealth by Saturday with overcast skies in the morning with showers.

But as we get into our afternoon hours of peak heating, instability will be at its greatest as the surface cold front linked to that low pressure system in the Great Lakes begins its sweep through the state. Ahead of that front, there will be sufficient wind shear, lift, and instability for strong to severe (potentially rotating) thunderstorms to develop in the afternoon and continue through the evening until the cold front passes into the Bay by Midnight.
Here's a time-line of the storm system on Saturday:

We'll be overcast in the Commonwealth by Saturday morning, and showers should expand east into central Virginia from the west before Noon.

Saturday afternoon, as mentioned above, is when we'll have our enhanced threat for severe thunderstorms.

Isolated thunderstorms that develop in central Virginia (east ahead of the main line of storms along the cold front) will be the most likely to rotate and potentially produce a few tornadoes.

Once the cold front starts sweeping through central Virginia, storms should be in a long "squall" line with damaging straight-line winds being our primary threat into the evening.

The cold front will reach the Chesapeake Bay around Midnight, pushing storms to the east.

Although we'll have the downside of a severe weather threat, the good news out of this storm system is that it should bring heavy rain into the entire Commonwealth, which is something we still need in most of the area! Widespread accumulations of a half-inch to around an inch look likely. Here's the potential rainfall accumulation by late Saturday night:
