Weather Summary for Iowa
National Weather Service Des Moines IA
549 PM CDT Mon Oct 15 2018

A cloudy morning and early afternoon gave way to blue skies across
Iowa. High temperatures this afternoon were in the mid 40s. There were
a few wind gusts near 15 miles per hour at times, however the winds
were not a big issue this afternoon. 

Across the rest of the Midwest, skies cleared up after the snow
showers yesterday. Visible satellite did show some snow covered 
fields this afternoon, especially northward. However with plenty of 
sunshine a lot of the snow has already melted. 

This week is looking dry and will be warming back up. Temperatures
will gradually rise into the mid 50s by the middle of the week, and
some locations may be looking at lower 60s in the weekend.

Historical Weather And Climate Facts For Today

A violent early season blizzard raked Minnesota and the Dakotas. Winds
gusted to 70 mph at Yankton SD, and snow drifts 10 to 15 feet high were
reported in northwest Iowa and southeast South Dakota. Saint Paul MN
reported a barometric pressure of 28.65 inches on the 16th. Railroads were
blocked by drifts of snow which remained throughout the severe winter to
follow. Gales did extensive damage to ship on the Great Lakes. (15th-16th)
(David Ludlum) (The Weather Channel)
Hurricane Hazel struck the Carolina coastline. The hurricane demolished
every pier along a 170 mile stretch from Myrtle Beach SC to Cedar Island
NC, and obliterated entire lines of beach homes. Hurricane Hazel also
destroyed 1500 homes as it moved inland with seventeen foot tides. Winds
between Myrtle Beach SC and Cape Fear NC gusted to 150 mph. Hurricane Hazel
caused 163 million dollars damage, and claimed the lives of 98 persons.
(David Ludlum) (The Weather Channel)
Iowa experienced its worst late season tornado of record. In just one
minute a twister tore through the town of Belmond leveling 75 percent of
the businesses, and 100 homes, causing more than eleven million dollars
damage. (The Weather Channel)
Unseasonably cold weather continued in the eastern U.S., with thirteen
cities reporting record low temperatures for the date. The low of 34
degrees at Montgomery AL was their coldest reading of record for so early
in the season. Lows of 32 degrees at Harrisburg PA and 34 degrees at
Parkersburg WV marked their third straight morning of record cold. (The
National Weather Summary)
The cold high pressure system responsible for the record low temperatures
in the eastern U.S. began to move out to sea, giving way to a trend toward
"Indian Summer". Thunderstorms developing ahead of a cold front produced
golf ball size hail at Altamont KS and hail two inches in diameter at Yates
City IL. (Storm Data) (The National Weather Summary)
Hurricane Jerry made landfall at Galveston TX at 6:30 PM (CDT). Winds at
the Galveston Airport reached 75 mph, with gusts to 100 mph. Tides along
the island were six to eight feet, and rainfall totals ranged up to
slightly more than six inches north of Beaumont. Three persons were killed
when their vehicle was blown off the Galveston seawall into the pounding
surf. Total damage along the Upper Texas Coast was estimated at fifteen
million dollars. Thunderstorms produced severe weather in Lower Michigan
during the late morning. Two persons were injured when a tree fell on their
camper at the Traverse City State park. While strong northerly winds
ushered much colder air into the central U.S., unseasonably warm weather
continued in the south central and eastern U.S. The afternoon high of 82
degrees at Bluefield WV was a record for October. (The National Weather
Summary) (Storm Data)
