Severe Thunderstorms in the Midwest and Arizona; Heat Continues in the Southeast and Southwest

Thunderstorms, some severe, may lead to scattered instances of flash flooding across the Midwest and Ohio Valley and southern Arizona. The threat will shift to the Mid-Atlantic coast on Thursday. Dangerous heat persists in the South and Southeast while building into the Southwest. Overnight lows will be so warm that little-to-no relief from the scorching daytime highs will be available.

Areas of fog, some dense will be found early this AM across far southeast Iowa, northeast Missouri and west central Illinois. The fog will be especially common in river valleys and other low lying areas, and in locations that received rainfall yesterday. The fog could bring sudden and significant reductions in visibility, so please stay alert on the roads and slow down when driving in fog.
After some early morning fog south, we'll see dry and nice weather take hold today as high pressure builds in. This will be short-lived though, as a series of cold fronts will bring a return of shower and storm chances late tonight through Friday evening. A few storms could be strong Friday afternoon with gusty winds the main concern. This all clears out just in time for the weekend, which looks to be beautiful!
