...Summary...
The National Weather Service in Mount Holly NJ has confirmed a
tornado near Stevensville in Queen Anne's County Maryland on
07/24/2017.

A waterspout developed over the Chesapeake Bay between Annapolis
and Stevensville, Maryland just south of the Chesapeake Bay Bridge
as estimated by radar velocity from the Baltimore-Washington 
Airport Terminal Doppler Weather Radar. The waterspout moved 
ashore at 129 AM in the Bay City Area of Kent Island and then
traveled northeast toward Stevensville, Maryland where it lifted
at 133 AM after being on the ground for about 2 miles.

Maximum winds were estimated at 125 mph which makes this an EF2
tornado. Several wood framed townhomes had the upper floors 
entirely lifted off along with the roof; several other homes had 
either roofs lifted off and tossed or received other damage. One 
business was destroyed. There was one injury to a person who was 
punctured by debris. In addition, there were trees and power lines
down and some gas leaks were reported along with a structure fire
to a home.

Well here's the sounding. Looks better than I thought.  That 78 DP really helping out the cape.

I would guess the unexpected stronger rotation, and resulting waterspout turned tornado, is at least partially attributed to the land-water differential heating.

I think Mt Holly dropped the ball on that warning last night and made the start time after the warning was issued. Radar def indicates strong couplet over bay at 115 coming onshore around 125 with really strong rotation. Warning issued at 127 saying tornado possible over Stevensville. The track starts at bay edge with 129 for a time stamp.

Makes no sense at all.

Was LWX posting statements about it? I went to bed just as WxWatcher and someone else were posting about the cell's potential. I wonder how much and how well the neighboring weather offices pass off potential events.

I do not know, I was asleep ;) . I imagine they had it up until it hit the east side of the bay and crossed into Mt Holly CWA.

Lol at you complaining about CWG and then trying to toot your own horn when you were posting links about how the HRRR was terrible with 2nd and 3rd round storms and asking what the point of the FFW were from LWX

Late evening meh severe storms in MD lol

I posted pics in the obs thread. Things got exciting here as that storm passed an hour ago. Rotation. Funnel cloud. Heavy rain with hail wind and sun all at the same time. Very unexpected and I guess local from nws lack of response but one of the crazier experiences I've had.

Better send those pics and stuff to LWX... LWX made no mention of rotation in their warnings

What?  No mention of being in the SLGT risk for Day 3?  And LWX being gung-ho in their AFD?

South/southwest flow returns for Thursday and with it, the
return of heat and humidity. Highs will rebound back to near
90F with dew points rising back to near 70F. As the frontal
system approaches late in the day, chances for
showers/thunderstorms increase, and SPC has placed the region in
a Slight Risk for severe thunderstorms. The greatest risk of
severe thunderstorms and heavy rain at this time appears that it
may come Thursday evening/night into Friday morning. See long
term discussion below for more information.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
Low pressure and its associated cold front will move into the
area Thursday night before passing through Friday. A southerly
flow ahead of this system will usher in plenty of moisture.
Latest guidance shows PWATs close to 2 inches.

An upper-level low associated with the cold front will also
approach Thursday night before passing through Friday. Deep
layer shear profiles should strengthen during this time. The
forcing from shortwave energy associated with the upper-level
low...the surface low and the cold front should trigger showers
and thunderstorms. Some thunderstorms have the potential to be
severe due to the strengthening shear profiles. Damaging winds
seem to be the primary threat...but the threat for isolated
tornadoes cannot be completely ruled out with the surface low
nearby. There is also a threat for locally heavy rainfall as
well. There is the opportunity for multiple rounds of
thunderstorms Thursday night into Friday...and with PWATS around
2 inches this poses a threat for torrential downpours and
localized flash flooding. Confidence in timing of heaviest
thunderstorms and location remain low this far out...but there
is an elevated threat for severe thunderstorms with localized
flash flooding Thursday night into Friday.
