Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 300 AM EDT Mon Jul 01 2019 Valid 12Z Mon Jul 01 2019 - 12Z Wed Jul 03 2019 ...Slight risk for severe weather and flash flooding along a stationary frontal boundary in the north-central U.S. and also parts of the northern High Plains... ...Heat and humidity to build through mid-week for the Southeast and Mid-Atlantic states... A nearly stationary frontal boundary draped from the Upper Great Lakes to the Central Plains will be a focal point for showers and thunderstorms the next couple of days. Storms could contain severe weather, along with heavy to possibly excessive rainfall. Both SPC and WPC have highlighted areas along the boundary within a slight risk for Monday. A stronger cold front dropping in from the north on Tuesday will increase chances for showers and storms, with another risk for severe weather, across parts of the northern High Plains. Relief is finally in sight for the Central U.S. from a several day long heat wave as the persistent upper ridge retreats southward. Temperatures Monday will cool to near or just above average, and all heat advisories have expired. Meanwhile, across the Mid-Atlantic and Southeast states, heat and humidity will be on the rise with a building ridge aloft, along with daily chances of afternoon and evening showers and storms.
