Tornadoes are never puny. This F1 damage is proof of the extensive nature of any tornado and while a warmer troposphere seems like a matter of simply installing better air conditioner, it is far more than simply 'comfort' measures on a hotter Earth. Just like the issue of Sea Level Rise appears to be whether or not folks can have homes at the beach or where exactly the beach will be redefined and therefore a 'real estate opportunity;' it carries far more brevity than simply presenting as a consumer issue.
Original F-scale:F1 Tornado Damage ((click here)
This wood-frame house was pushed bodily off its concrete block foundation by the Spencer SD tornado of 30 May 1998 (a tornado which later did marginal F4 damage in the town of Spencer). Here, the house had no bottom anchoring at all. It was simply resting on its foundation by gravity alone; so it was easy for relatively weak winds near the edge of the tornado to slide the house aside with minor structural damage. It experienced partial roof removal, only on the windward (near) side; therefore, this damage site was rated F1.
While this F1 Tornado-Reflectivity scan is a bit dated, the point is while there is a higher tornadic event occurring, it isn't unusal for an F1 to be a part of a larger parent system.
Description (click here): There are several things to note from the F1 Tornado-Reflectivity scan. At the time of the scan, the Dozier tornado was in progress and was associatied with the high-based mesocyclone #451. The surface-based mesocyclone #278 would seem a more likely tornado candidate in the classic sense, but it produced only a brief tornado. The Dozier tornado persisted for six minutes.
Also of note is mesocyclone #299. This is what remained of the Kellerville tornado which lifted at 0032 UTC. The development of the Dozier storm disrupted the southwesterly inflow into the Kellerville tornado. Had this not taken place, the Kellerville tornado may very well have maintained itself. As it stood, the Kellerville tornado tracked 9 miles over 46 minutes.
Example of F1 Tornado :: Waterspout on the Miles River near Saint Michael's, Maryland. It later made landfall as an F1 tornado, downing trees and flipping a boat. NWS
The appearance of an F1 Tornado can at times be deceptive, in that it can look more like a 'Dust Devil' while it's core is definately a severe storm.

High Winds Cause Damage in Ala., Miss. (click here)
By JAY REEVES – 1 day ago
BIRMINGHAM, Ala. (AP) — Powerful thunderstorms packing heavy rain and high winds pushed across Alabama and Mississippi on Thursday, causing scattered property damage and at least two traffic deaths.
Several tornado watches or warnings were issued Thursday in both states, but no touchdowns were immediately confirmed.
In Mississippi, a motorist was killed after colliding with a Lamar County deputy head-on during the height of the storm, while a single-vehicle accident in Jones County claimed another life.
Authorities there said the vehicles involved in both crashes may have hydroplaned during downpours, though investigations are continuing.
In Alabama's Lamar County near the Mississippi line, at least two houses were destroyed in Sulligent, the National Weather Service said.
In nearby Vernon, rescuers freed a woman who was pinned in her vehicle after a tree fell on it, said Don Dollar, an administrative assistant with the city. She was taken to a hospital, but her condition was not available Thursday afternoon.
Just across the state line, buildings and buses were damaged at a school in Caledonia, Miss., said Lea Stokes, a spokeswoman for the Mississippi Emergency Management Agency....

VANCOUVER, Wash. -- A tornado downed power lines, uprooted trees, sent shopping carts flying into cars and demolished a rowing club Thursday in Vancouver.
There were no reports of injuries as the tornado cut through four miles from Vancouver Lake at the west edge of the town through the Hazel Dell area.
"It looks like we came through this pretty good," said Jim Flaherty, spokesman for the Vancouver Fire Department.
Utility officials said about 800 people lost power.
"I saw it coming and thought, 'Whatever that is, it's scary,'" said Kym Calder, 47, who ran into a nearby church for shelter when she saw the funnel cloud ahead of her....
