542 PM CDT Tue Mar 20 2018

Conditions across Iowa this afternoon were cloudy. After the light
snow showers rolled through the northwestern portion of the state, a
few flurries and a few light scattered sprinkles were reported at
scattered locations. Temperatures this afternoon only reached the mid
30s, with light northerly winds of 5 to 10 miles per hour. As of the
early evening hours, visible satellite showed all of Iowa under thick
cloud cover. A few stations across the state were reporting light 
rain showers under the cloud cover. 

Across the rest of the Midwest, conditions today have been cloudy. 
Clear skies are way out west over the High Plains. Temperatures have 
mainly been in the mid 30s, with generally northerly flow. There have 
been scattered light rain showers and snow flurries across the region.

For this evening, the cloud cover will prevent temperatures from
dropping. Overnight lows will be in the upper 20s to lower 30s. Winds
will be calm. Mist and localized fog can be expected across Iowa this
evening and into the morning hours which will reduce visibility. For
tomorrow, temperatures will be in the mid 40s for most of the state,
with a few locations near the Missouri border reaching the lower 50s.
Overall, conditions should be dry in terms of precipitation. Activity
will pick up toward the end of this week, with a few scattered rain
showers on Thursday, and more widespread precipitation on Friday
across Iowa.

Historical Weather And Climate Facts For Today

A tornado swarm occurred in the Deep South. Between late afternoon and
early the next morning severe thunderstorms spawned 31 tornadoes in
Alabama, Mississippi, Georgia and Tennessee. The tornadoes killed 334
persons and injured 1784 others. Northern Alabama was hardest hit.
Tornadoes in Alabama killed 286 persons and caused five million dollars
damage. (David Ludlum)
Severe thunderstorms spawned thirty-one tornadoes across Arkansas,
Tennessee, Missouri, Mississippi, Alabama and Kentucky. The tornadoes
killed 343 persons and caused 15 million dollars damage. Arkansas and
Tennessee each reported thirteen tornadoes. The towns of Judsonia AR and
Henderson TN were nearly wiped off the map in what proved to be the worst
tornado outbreak of record for Arkansas. A tornado, one and a half miles
wide at times, left a church the only undamaged building at Judsonia.
