The nation’s weather

Weather Underground midday recap for Wednesday, April 17, 2013. A dangerous day was set up for the middle portion of the country Wednesday as a powerful storm brought a variety of significant weather events to the region.

The most dangerous of this weather was the threat of severe weather from northern Texas through Missouri and Illinois due to a strong cold moving through that area. While no tornadoes had yet formed by the early afternoon, the Storm Predictions Center had issued a moderate risk of severe weather for the area due to the possibility of severe thunderstorms, strong winds, large hail, and tornadoes into the evening. Residents are asked to watch local weather conditions into the evening and be prepared to protect life and property.

Even without a tornado during the first part of the day, the associated cold front produced heavy rain for Iowa and Illinois. Some areas in Iowa had reported up to 3 inches of rain by the early afternoon, prompting flooding concerns due to surging rivers and streams.

The second effect of the storm was the Winter conditions it provided from the Northern Rockies through the Northern Plains. While significant snow was expected to continue to produce significant snow into the evening and Thursday, several inches of snow had already fall from eastern Colorado through South Dakota.

Meanwhile, an area of showers and thunderstorms developed over the Appalachians. The rest of the eastern third of the county remained dry.

The Southeast rose into the 70s and 80s, while the Northeast saw temperatures in the 50s and 60s. The Northern Plains rose into the 30s and 40s, while the Northwest saw temperatures in the 40s and 50s.

Temperatures in the Lower 48 states Wednesday have ranged from a morning low of -2 degrees at Yellowstone, Wyo. to a midday high of 95 degrees at Dryden, Texas
