Severe Weather and Heavy Rainfall from the High Plains to the Ohio Valley; Heat Continuing in the Central Plains and Southeast

A stationary front will be the focus for daily showers and thunderstorms capable of widely scattered flash flooding and severe weather from the High Plains to the Ohio Valley. Monsoonal thunderstorms could cause local flash flooding across the Southwest and the Great Basin. Dangerous heat continues across the Central Plains and Southeast. Many areas will see their hottest temperatures of the year. Read More >

Eclipse Overview

On Monday, August 21, 2017, all of North America was treated to an eclipse of the sun. Anyone within the path of totality saw one of nature’s most awe inspiring sights - a total solar eclipse. The path, where the moon completely covered the sun and the sun's tenuous atmosphere - the corona - was seen from Salem, Oregon to Charleston, South Carolina, and included parts of central and east central Missouri, as well as southwest Illinois. Observers outside the path still saw a partial solar eclipse where the moon covered part of the sun's disk. Many scientific experiments and observations were done during the eclipse. Here is a satellite loop showing the eclipse and how the temperatures responded. This GOES-16 data is from CIMSS (University of Wisconsin) and is considered non-operational. There are also a few temperature traces posted for select locations along the path of totality in the NWS St. Louis county warning area. You can really see how the temperature dropped anywhere from 3 to 9 degrees during the total eclipse of the sun!
