As an active weather day is shaping up in the United States, we will be maintaining this blog with the latest information. Here is what we will be focusing on covering:
Parts of the Plains and Midwest are under a moderate risk of severe weather this afternoon and evening. The moderate risk stretches from Iowa and northern Missouri through southern Wisconsin and adjacent areas of Indiana and Michigan. The most significant threat will be tornadoes, however residents in the area should be prepared for very heavy rain, large hail, and strong winds as well. A slight risk of severe weather also stretches from the Texas Panhandle through Michigan.
Also of note is the chance of tropical development off the east coast of Florida. A system has been spinning off the coast for several days and the National Hurricane Center has stated that Tropical Storm Watches could be posted along the coast as the system has become better organized.
