Forecast for Saturday, July 20, 2019

The big story this weekend continues to be an oppressive and dangerous heat wave gripping much of the Midwest to Eastern U.S. where a large number of excessive heat warnings, watches, and heat advisories remain in effect. On Sunday, the greatest heat threat will be from the Carolinas to Maine where daytime highs in the mid to upper 90s combined with high dewpoints will make it feel like its near 100 to 110 for many. Even overnight will provide little relief as temperatures struggle to get below the upper 70s or even low 80s. This may challenge or break daily record high minimums for a large number of stations across the Ohio Valley and Northeast. Please see www.weather.gov for the latest on the coverage of warnings, and also tips on how to stay safe in this heat.

A cold front dropping into the Plains this afternoon will bring showers and thunderstorms and cooler temperatures to parts of the Central Plains and Midwest by Sunday. Some storms could be severe, with the best chance for this across the Upper Midwest and Upper Great Lakes tonight. Locally heavy rainfall could lead to flash flooding as well in these regions. The front should progress slowly south and eastward, reaching the East Coast by Monday and finally bringing a much needed relief to the relentless heat. Showers and thunderstorms will accompany this boundary, with heavy rainfall possible across parts of the Tennessee, lower Ohio, and into the Mid-Atlantic states on Monday. WPC highlights this region within a slight risk for flash flooding. Elsewhere, expect typical diurnal showers and storms across the Southeast on Sunday and Monday, while much of the West should stay mostly dry and cooler than normal through the short range period.
