Winchester VA

In the past two weeks we had enjoyed one of the warmest January
stretches in recent memory. My mean temperature averaged 46.1º, or
16º above normal, from Jan 1 to 14. The reading would have normal here
about April 1st. It's also the normal Jan temperature Jackson MS. It was
only below freezing one night in the new year.

Several warm temperatures were broken in the first 2 weeks. (The ones
from the previous week are below.) I had a high of 68º on Thursday.
WINC radio had a 70º. Although WINC keeps the "official" NWS data for
my area, they only keep monthly extremes. The record locally for
Thursday was 68 in 1972.

The Arctic cold front moved thru the region Friday morning. It was
accompanied by about 1" of rain locally. I measured .98". East of the
Blue Ridge Mountains, 2 to 3" were common.

The NWS offices serving VA each issued 3 tornado warnings, mostly in the
overnight hours Thur night & early Friday morning. Several severe
thunderstorm & flash flood warnings were also issued.

The Baltimore/Washington NWS office had issued a flash flood watch from
4pm Thursday until 1pm Friday. But at 4am Friday, it was dropped. To me,
it was a surprise, since the back edge of was still in WV, and there
were moderate pockets embedded.

Flash flood warnings were issued for the Washington suburbs between 5
and 7am, which ended later in the morning. There were several water
rescues and many flooded roads.
A few river stages on the Potomac basin reached bankful, although many
only got to half to 3/4 full. Minor flooding was occuring on the James
River basin Saturday. (For more details, click on the messages of the
3rd column at http://www.erh.noaa.gov/marfc/Forecasts/AKQ_index.html )

In the Richmond area, one F-1 tornado with a 6 mile path of mostly tree
damage was confirmed.

In Danville, an apartment building lost it's roof from straight line
winds.

By 11pm Friday, it fell below freezing for on the 2nd time this month.
The dew point fell from 60 at midnight to 20 in the evening!

I found these 2 links talking about the South Asia earthquake & tsunami
last month. The first story is about how the North Pole has shifted, and
that Earth's rotation is likely a few millionths of a second a day
shorter. The second story talks about the detection of tsunamis from
satellites. And scroll down to near the bottom it talks about the waves,
in time, reached _ALL_ of the Earth's ocean coastlines, however small.
There is an animation available, but since it's a 4 day loop, I would
recommend only broadband users try to load it.

How the Earthquake affected Earth
The Dec. 26th Indonesian megathrust earthquake quickened Earth's
rotation and changed our planet's shape.

Although we are now cold, we still have no snow storms in the forecast.
We have clippers due with threat of flurries or a few snow showers late
Sunday and again Wednesday. So far this winter, only 1 day with even
flurries. We are LONG overdue for the first snowfall of the season.
