According to recent reports, more than 4 million people in Miami and Fort Lauderdale, Florida, remain under a flood watch until Saturday evening. Although the incoming showers are expected to be lighter than the previous week, the saturated ground leaves little room for new rainfall, increasing the risk of ponding and flash flooding. Both cities have already seen over 14 inches of rainfall in the past seven days, which is considered a 25-year event with a 4% likelihood of occurring in any given year. Climate experts warn that human-induced climate change is exacerbating these heavy rain and flood events.

In South Florida, Sunday may bring some relief as the region is expected to experience a mostly dry day. However, there is still a possibility of isolated thunderstorms. Meanwhile, the Upper Midwest, from Wisconsin to Nebraska, is bracing for heavy rainfall and severe weather. Cities like Omaha, Lincoln, and Des Moines may see strong supercells potentially spawning tornadoes, damaging winds, large hail, and flash flooding.

In the Southwest, an excessive heat warning has been issued for parts of Arizona and southern California until Sunday. Temperatures in Phoenix could reach 113 degrees, while Tucson may experience temperatures of 110 degrees. The situation is equally severe in southern California, where places like Palm Springs and Imperial could face scorching temperatures ranging from 115 to 118 degrees. El Paso, Texas, is also under an excessive heat warning, with a heat index value exceeding 100 degrees.

Experts have identified a heat dome that is beginning to move eastward across the country, bringing the potential for record-breaking temperatures and the hottest conditions experienced so far this year. On Sunday, cities like St. Louis, Nashville, and Little Rock may witness daily record high temperatures, with potential highs around 100 degrees. The extreme heat risk continues on Monday, affecting areas from Kansas City to St. Louis and Des Moines, possibly setting new record daily highs in cities like Chicago, Indianapolis, and Pittsburgh.

The extreme heat is expected to persist into Tuesday, affecting cities like Chicago, Green Bay, Detroit, Cincinnati, and Louisville. By Thursday, the extreme heat risk may extend to the Northeast, encompassing areas from Ohio to Maine. This could potentially include New York City for the first time this year.

As weather conditions continue to intensify across different regions, residents are encouraged to stay informed and take necessary precautions to ensure their safety.
