Weather Summary for Iowa
National Weather Service Des Moines IA
1058 AM CST Sat Dec 16 2017

It has been a quiet start to the day across much of the Upper Midwest,
including here in the state of Iowa where temperatures started out
at around 30 to 35 at sunrise this morning. Well above normal highs
are expected this afternoon as a warm air mass and plentiful sunshine
spread over the area. Expect highs in the mid 40s to mid 50s with
mainly light winds. More cloud cover will likely hold temperatures
back a few degrees on Sunday, including a chance for light rain or
snow in south central and southeast Iowa.

Above normal temperatures and dry conditions are likely though the
first half of next week. Attention then turns to an area of low
pressure that will cross the northern Plains late Wednesday night into
Thursday, which will deliver cold temperatures and possibly the first
accumulating snowfall of the season to much of the state. While it is
still too early to determine snowfall amounts, those with travel 
plans during this time period should check ahead for forecast updates 
and potential impacts to local travel conditions.

Historical Weather And Climate Facts For Today

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)
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: 
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
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)
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)
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)
