.DISCUSSION...

It was a nice afternoon by December standards. Surface high 
pressure over the southeast was bringing sunshine mixed with thin 
cirrus clouds, and temperatures mainly in the lower 50s. 

For tonight, a disturbance will lift rapidly northward out of 
Mexico. This will bring increasing clouds, mainly late tonight.
Our far western counties could see a few light showers by
daybreak. Forecast soundings show very dry low levels through 12Z,
so virga will likely occur for a while before rain reaches the
ground. Lows will be in the 30s.

On Sunday, the disturbance will lift quickly to the Great Lakes
region. As it does, it will drag a swath of moisture across Mid 
TN, resulting in light showers. Most locations will have less than
one quarter inch of rain. Most of the showers will fall between 9 
AM and 1 PM CST. After that, low level moisture will linger, 
keeping low clouds in place with just a few remnant showers or 
patches of drizzle. Highs are expected to reach around 50.

For Sunday night into Monday, low level moisture will linger, so 
some areas of drizzle and fog can be expected Sunday night through
daybreak Monday.Temps will not fall much under the clouds, with
lows in the 40s. Look for a few breaks in the clouds Monday 
afternoon with mild temperatures reaching the 50s to around 60. 

Monday night through Wednesday, the next system will come out of 
the Southwest States. We expect mainly cloudy skies with scattered
showers. The greater rain chances and amounts will occur over our
southern counties. Temperatures will be mild with lows in the 
40s, and highs in the low 60s Tuesday, and 50s Wednesday. 

Thursday still looks dry and mild with highs around 60. 

For Thursday night and Friday, a large deepening trough over the 
Central U.S. will begin to push eastward, bringing increasing
chances for showers along an advancing cold front. 

For Friday night through Christmas, our forecast models are having
a lot of difficulty resolving a changing and probably very messy 
wx pattern. Movement and location of the frontal zone varies 
significantly across model solutions. It is possible the frontal 
zone could stall, making it a very rainy weekend into Christmas. 
It is also possible that cold air could build enough to bring some
wintry wx along the northern edge of the precipitation shield 
somewhere across TN or surrounding states. It is also possible the
front could get pushed through with cold and dry conditions
arriving for Christmas. At this point, we simply do not know. The
important message is that wet or wintry wx could occur somewhere 
over the region this weekend and into Christmas. Folks should keep
this in mind, check updated forecasts through the week, and think
about the possible need for flexibility with holiday travel plans
and activities.

Historical Weather And Climate Facts For Today

DECEMBER 16TH
HISTORIC WEATHER EVENTS
...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)
...1987...
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
Malibu Beach, and Disneyland was closed due to the weather for only the
second time in twenty-four years. A winter storm which began in the
Southern Rockies four days earlier finished its course producing snow and
high winds in New England. Snowfall totals ranged up to 19 inches at
Blanchard ME. (The National Weather Summary) (Storm Data)
...1988...
Fairbanks AK reported freezing rain and record warm temperatures. The
afternoon high of 41 degrees was 43 degrees above normal. Snow and high
winds continued to plague the mountains of southern California. Mount
Wilson CA reported two inches of rain in six hours during the early
morning, and a storm total of more than 3.50 inches of rain. (The National
Weather Summary)
...1989...
Fifty-seven cities from the Southern and Central Plains to the Appalachians
reported record low temperatures for the date, including North Platte NE
with a reading of 17 degrees below zero. Squalls in the Great Lakes Region
produced 18 inches of snow at Syracuse NY, and 30 inches at Carlisle IND.
Low pressure brought heavy snow to northern New England, with 18 inches
reported at Derby VT and Saint Johnsbury VT. (The National Weather Summary)
