Last week, several rounds of storms moved through areas of the Midwest, producing significant wind gusts and flash flooding. Another cold front will arrive shortly after the previous front leaves, sparking a new wave of severe storms, including potential for flash flooding.<h1>Forecast</h1>Along the front, isolated to scattered severe storms have been moving through, prompting severe thunderstorm and tornado warnings. Storms will continue overnight across these areas and new ones will likely form into Wednesday afternoon.<video src="https://media.weathernationtv.com/app/uploads/2026/08/08-18 rnc overnight-1787102698299.mp4" controls="true" width="100%"></video><h1>Outlooks</h1>The SPC has maintained a SLIGHT (level 2 out of 5) risk for severe weather across the Plains and Midwest overnight.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-18 192304-1787102611107.png">The same frontal system will continue to stall out into more of the Mid-South as we head into Wednesday. A slight risk close to the low has been issued into Arkansas and Missouri.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-18 192309-1787102642354.png">By Tuesday, heavy rain will become a bigger hazard, with scattered flash flooding possible for areas in dark green (below). Soils are saturated from last week's rain in many of these areas, meaning runoff or flooding will occur more quickly than normal. Totals can get up to 3" in some isolated spots.<video src="https://media.weathernationtv.com/app/uploads/2026/08/2026-08-18 03-43-06-1787046202452.mp4" controls="true" width="100%"></video><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-18 034157-1787046130096.png">

A ridge of high pressure has dominated the southern U.S., with multiple records being broken daily. Miami, Florida, saw a record of 100° today, which ties the previous record of 100°, set in 1942. This is only the second time Miami has reached this temperature since records began in 1895! The heat alerts will remain in place across the south through Wednesday.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-18 192025-1787102440063.png">Feels-like temperatures remain dangerously hot across the central and southern United States.

Lala continues to move westward of Kauai, still bringing bands of heavy rainfall and gusty winds to portions of the smaller Hawaiian Islands.The Hawaii Department of Transportation reported that parts of Highway 11 on the Big Island were shut down due to flooding. More than 130,000 customers lost power Saturday at the height of the storm. As the storm moves west-northwest, expect conditions to slowly improve as the blustery showers back off.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2088807962383143316" src="https://x.com/WeatherNation/status/2088807962383143316"></div>Flooding continues to be a problem for Hawaii as all of this rain makes it back into the ocean. Some areas picked up more than 3 FEET of rain thanks to Lala!<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-17 101407-1786983268612.jpg">Lala, now over open Pacific waters, has strengthened back into a hurricane. According to the NHC, Lala is expected to remain a category 2. At this point, additional impacts to the Hawaiian Islands are over, but surf and rip currents will be something to watch. Larger swells generated by the system could amplify these coastal concerns.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-18 192701-1787102828054.png">
