What is now Tropical Depression Laura continues to weaken as it moves northeastward through the Middle Mississippi Valley and into the Ohio Valley today, and crosses the Mid-Atlantic states on Saturday. Laura will bring heavy rain, strong thunderstorms and gusty winds to locations along and near its track, with both SPC and WPC highlighting slight risks of severe weather and flash flooding, respectively, before it eventually exits the East Coast as a Post-Tropical Cyclone early Sunday. Meanwhile, north of Laura, a slow moving warm front draped across the Upper Midwest to Lower Great Lakes will trigger showers and thunderstorms, some of which could contain heavy rainfall and severe weather on Friday. WPC contains this region within a slight risk of flash flooding, and SPC shows a slight to enhanced risk especially across parts of eastern Iowa into southern Wisconsin and northern Illinois. The attendant cold front will slide eastward across the Central Plains, Mississippi Valley, and the Eastern U.S. into the weekend with additional rounds of showers and storms likely along and ahead of the boundary. Temperature-wise across the country, one more day of heat and humidity is likely from the Midwest into the Mid-Atlantic states on Friday, as Laura's remnants and the cold front to the west should usher in a cooler airmass by the weekend. Although daytime highs should hover near (or below) normal, plenty of moisture in the air will keep overnight mins warm, with record warm lows possible from the South to the Mid-Atlantic Saturday morning. The nations hot spot during the next few days will be across parts of northern and central Texas where triple digit heat and the potential for record breaking temperatures are possible. Heat advisories are currently in effect for this region. Across the Northwest, the combination of wind, heat, and dry thunderstorm activity may ramp up the fire risk again this weekend with SPC indicating an elevated to critical risk in this area on Saturday. A fire weather watch is currently in effect, while farther South, some parts of Oregon and central California remain in air quality alerts due to recent and ongoing wildfires.
