.DISCUSSION...

Surface ridge has shifted east of Middle Tennessee, with much
welcome return flow now establishing itself, although we'll have
to endure one more cold morning. The southerly flow will start to
bear fruit a few hours from now as temperatures warm into the 
50's most areas across the mid state. In spite of copious and 
well- deserved sunshine today, things will change quickly. A 
shortwave currently brewing over northern Mexico will gain steam 
over the next 24 hours and move rapidly toward the northeast and 
bring rain to the mid state on Sunday. A few echoes may slip 
across the Tennessee River prior to 12Z Sunday, but the primary 
focus appears to be 12-18Z Sunday. The deepest moisture will pull 
east of Middle Tennessee after 18Z, with lesser POP's lingering 
into the afternoon and evening. The forecast surface pattern 
really doesn't portend any sort of frontal passage until late 
Tuesday or Tuesday evening, so look for temperatures to continue 
escalating until the middle of next week, when we'll see a slight,
brief cooling trend. Both the ECMWF and GFS continue to bring a 
much stronger cold front through Middle Tennessee on Friday. That 
they are in such good agreement this far out is unusual.

...1835...
New England experienced one of their coldest days of record. At noon on
that bitterly cold Wednesday the mercury stood at four degrees below at
Boston, 15 degrees below at Norfolk CT, and 17 degrees below at Hanover NH.
The temperature at Boston was 12 degrees below zero by sunset. Gale force
winds accompanied the severe cold, and that night a great New York City
fire destroyed much of the financial district. (David Ludlum)
...1869...
A bill was introduced in the House of Representatives, 41st Congress, 
calling for the taking [of] meteorological observations at the military 
stations in the interior of the continent, and for giving notice on the 
northern lakes and Atlantic seaboard of the approach and force of storms. 
This would be signed in to law February 9, 1870, by President Grant, 
establishing what would come to be called the National Weather Service. You 
can see the actual bill on-line at: 
 here.
...1917...
An ice jam closed the Ohio River between Warsaw KY and Rising Sun IN. The
thirty foot high ice jam held for 58 days, and backed up the river a
distance of 100 miles. (David Ludlum)

A Pacific storm battered the coast of California with rain and high winds,
and dumped heavy snow on the mountains of California. Winds along the coast
gusted to 70 mph at Point Arguello, and winds in the Tehachapi Mountains of
southern California gusted to 100 mph at Wheeler Ridge. Snowfall totals
ranged up to 24 inches at Mammoth Mountain. Snow fell for two minutes at

high winds in New England. Snowfall totals ranged up to 19 inches at
Blanchard ME. (The National Weather Summary) (Storm Data)
