Weather Summary
Kari Kiefer
Weather Underground midday recap for Wednesday, June 19, 2013. A transitional weather day occurred Wednesday as some areas of the country experienced active weather. The most active weather developed in the Plains as a storm moved through the Rockies and into the western Plains. This feature carried some moisture that produced areas of scattered showers and thunderstorms from the Oklahoma panhandle through Nebraska. Some of these thunderstorms were quite strong and were related to the thunderstorm that produced a tornado at the Denver International Airport Tuesday.

Meanwhile, a front moved along the eastern seaboard and produced areas of scattered showers and even some thunderstorms from Virginia through the Northeast coast. As the front moved off the coast, rain diminished for most areas. The one exception to this was in North Carolina where the front lingered through the afternoon.

Elsewhere, scattered showers developed through the Northwest and Intermountain West as a Summer storm system moved through the area.

A large high pressure system anchored over the Great Lakes provide dry conditions for much of the northern half of the country from the Plains through much of New England.

The Northeast rose into the 70s and 80s, while the Southeast saw temperatures in the 80s and 90s. The Southern Plains rose into the 90s and 100s, while the Southwest saw similar temperatures.

by additional information received. The Montgomery County segment
below has been refined by a slight westward revision of the

The National Weather Service in Sterling expresses its
appreciation to those who assisted in conducting surveys and
provided information used during the surveys... including members
of the emergency management... Skywarn storm spotters... and members
of the public affected by these storms.

... Summary...

Eyewitness accounts... radar imagery... and a ground survey concluded
a long track EF-0 tornado occurred in Montgomery County Maryland
on the afternoon of June 13th 2013. Peak winds were estimated at
75 mph. Damage was almost entirely from downed trees. In that
regard numerous homes and a few parked vehicles were damaged by
trees falling onto them. No injuries have been reported.

First consistent damage was noted along Bonnie Dale drive and
Glenhurst court and Road where several trees were downed in the
community. Also... near the intersection of Turkey Foot Road and
Jones Lane in southwest Montgomery County near North Potomac
Maryland a few large trees were over the Road. The tornado raced
east at nearly 60 mph to the northern section of Rockville Maryland.
At least 14 homes were significantly damaged by uprooted trees. As
it continued east to the Norbeck and Aspen Hill area 30 trees were
uprooted in the Manor Country Club Golf course as well as numerous
homes damaged in the surrounding communities from tree damage. Tree
damage was noted along the intercounty connector Route 200 at the
Layhill Road exit. Finally a few trees were downed in Spencerville
and Burtonsville.

Based on the damage, this tornado is rated EF-0, with estimated
wind speeds of 75 mph. The 18.0 mile damage path length was covered
in 18 minutes and had consistent small branch damage with
occasional areas with significant tree damage.

Additionally there was a parallel 7 miles path of damage through south
Rockville and Glenmont Maryland with similar tree damage. This
area was found to be straight line winds from the outflow just
south of the tornado from the parent supercell storm.

The National Weather Service would like to extend its thanks to Montgomery
County fire who confirmed the tornado on the ground during the storm
and Montgomery County emergency management who provided invaluable
assistance during the ground survey.
