Weather Summary for Iowa
National Weather Service Des Moines IA
1038 AM CDT Wed Aug 15 2018

Generally cloudy conditions remained over much of the state overnight
and this morning, making for some mild temperatures as well. Lows
struggled to get much below the mid 60s, with the vast majority of the
area in the mid to upper 60s for lows. Isolated showers also continued
overnight, mostly north of the Interstate 80 corridor. Overall, a
fair number of locations over the southern half of the state
experienced rainfall totaling around a half inch to an inch. A few 
lucky spots in southwest Iowa were in the one to two inch rain. Not 
much had changed by late this morning, with a few scattered light 
showers between Highways 20 and 30, but otherwise partly cloudy to 
mostly cloudy skies prevailed elsewhere. Temperatures also struggled 
to move too much underneath the cloud cover, with most locations still
in the low to mid 70s. 

Relatively unsettled conditions will prevail through Monday with
another pair of shower and storm chances moving through after the
current system departs later today. The next opportunity will begin to
enter the state Thursday morning from the west, and linger across the
state well into Friday. Then after a quiet Saturday and first portion
of Sunday, another system looks to move in from the south late Sunday
and on into Monday. At this point in time, any rain over the southern
third to half of the state will be welcomed with open arms given the
dry to drought conditions ongoing. Temperatures throughout this time
frame will be on the cooler side too with highs predominantly in the
low to mid 80s. Early next week temperatures look to fall a few more
degrees, with highs in the upper 70s.

Historical Weather And Climate Facts For Today

Tornadoes were reported in Connecticut, Rhode Island, Massachusetts, and
New Hampshire. Wethersfield CT was hard hit by the tornado outbreak. (David
Saint Louis MO was deluged with a record 8.78 inches of rain in 24 hours.
(The Weather Channel)
The "sundance fire" in northern Idaho was started by lightning. Winds of 50
mph carried firebrands as much as ten miles in advance to ignite new fires,
and as a result, the forest fire spread twenty miles across the Selkirk
Mountains in just twelve hours, burning 56,000 acres. The heat of the fire
produced whirlwinds of flame with winds up to 300 mph which flung giant
trees about like matchsticks. (David Ludlum)
Thunderstorms developing ahead of a sharp cold front produced severe
weather in the Upper Midwest during the afternoon and evening hours, with
Minnesota and eastern South Dakota hardest hit. A thunderstorm in west
central Minnesota spawned a tornado at Eagle Lake which killed one person
and injured eight others. A thunder- storm in eastern South Dakota produced
softball size hail at Warner. (The National Weather Summary) (Storm Data)
Thirty five cities in twenty states in the north central and northeastern
U.S. reported record high temperatures for the date, including Lamoni IA
and Baltimore MD, where the mercury hit 105 degrees. Temperatures 100
degrees or above were reported in twenty-two states. Pierre SD was the hot
spot in the nation with a high of 114 degrees. Bluefield WV reported eight
straight days of record heat. (The National Weather Summary)
Evening thunderstorms in eastern New Mexico produced wind gusts to 66 mph
at Clovis. Evening thunderstorms in West Texas produced baseball size hail
around Hereford, Dimmitt, Ware and Dalhart. (The National Weather Summary)
