Weather Summary for Iowa
National Weather Service Des Moines IA
346 AM CST Tue Dec 31 2024

Today: 

Low pressure moving from Missouri into Central Illinois overnight
produced a broad area of light rain and snow across central and
southern Iowa early this morning. There were spotty areas of snow
accumulations with a few areas receiving around an inch or so.
Most primary roads and highways remained wet although less traveled
roads did become slushy in areas. Otherwise, northwest winds increased
and were common from 10 to 20 mph with gusts to almost 30 mph at 
times. 

The light precipitation is expected to come to an end this morning as
the system pulls away from the state. Some minor snow accumulations,
generally less than an inch remain possible in far south central to
southeast Iowa through mid morning, otherwise the north winds persist
for much of the day as cooler air arrives. Additional flurries are
expected late this afternoon into the evening as another weak system
passes through the state. 

Tonight and beyond: 

Any flurries are forecast to end tonight with clearing expected toward
daybreak on New Years Day. Mostly sunny skies will greet the New Year
with near normal temperatures in the mid 20s to lower 30s. However,
a clipper system approaches the state on Thursday with light snow
overspreading much of central into southern Iowa. Minor accumulations
are forecast by Thursday evening along with the arrival of cooler air.
Highs by Friday are forecast to remain in the teens to lower 20s over
much of the state as cold polar air overspread the Midwest.

Historical Weather And Climate Facts For Today

/////////////////////////
JUNE 22ND...HISTORIC WEATHER EVENTS
...1947...
Twelve inches of rain fell in forty-two minutes at Holt MO establishing a
world rainfall record. That record was tied on January 24-25, 1956, at the
Kilauea Sugar Plantation in Hawaii, as their state record was established
with 38 inches of rain in 24 hours. (The Weather Channel)
...1972...
Hurricane Agnes deluged Pennsylvania and New York State with torrential
rains resulting in the most costly flood in U.S. history. In the Middle
Susquehanna Valley of Pennsylvania, 24 hour rainfall amounts were generally
8 to 12 inches, with up to 19 inches in extreme southwestern Schuylkill
County. At Wilkes-Barre PA the dike was breached destroying much of the
town. Flooding resulted in 117 deaths and 3.1 billion dollars damage.
(David Ludlum)
...1981...
A young woman from Lubbock TX was struck by lightning. The bolt of
lightning struck just above her right shoulder near her neck, and passed
right to left through her body, tearing her warm-ups, causing her tennis
shoes to explode, and lifting her two feet into the air. (The Weather
Channel)
...1992...
Record cold prevailed in the eastern U.S. with 67 low temperature records for 
the date tied or broken.  Indianapolis, Indiana dipped to 37 degrees to set a 
new all-time record low temperature for June and the coldest summer temperature 
ever.  In sharp contrast, it was a furnace in the Pacific Northwest with Eugene 
and Medford, Oregon setting new all-time record high temperatures for June with 
102 and 111 degrees, respectively.
