Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 409 PM EDT Sun Aug 02 2015 Valid 00Z Mon Aug 03 2015 - 00Z Wed Aug 05 2015 ...Showers and thunderstorms for the Great Lakes-Northeast -- some may be strong to severe... ...Additional heavy rains possible for the Southeast... ...Cooler temperatures ahead for the Northwest... Late this afternoon and evening, showers and thunderstorms will continue to move out ahead of an area of low pressure moving across the upper Great Lakes into southeastern Canada. Some of these storms may be strong to severe and produce locally heavy rains. As this low lifts into Canada overnight Sunday into Monday, storms are expected to develop along the trailing cold front as it pushes east from the lower Great Lakes region across the Northeast. Cold air filling in behind the front will result in high temperatures remaining 5 to 10 degrees below normal across much of the upper Midwest on Monday. Additional rounds of showers and thunderstorms, with locally heavy to excessive rains, can be expected from coastal South Carolina and Georgia back to the southeast across northern Florida and along the eastern Gulf Coast. The greatest potential for heavy rains is expected to remain centered across the northern and central Florida peninsula -- where tropical moisture pooling along a stalled frontal boundary is expected to interact with an slow moving area of low pressure. Following another day of scattered showers and thunderstorms across portions of California, the Southwest and the Great Basin, drier conditions are expected across California and the Southwest on Monday. Showers and thunderstorms are forecast instead to focus further to the north and east. Some storms may develop across portions of the Pacific Northwest and the northern Rockies. By late Monday into Tuesday, a cold front dropping from the northwest will begin to impact the region -- bringing an end to the stretch of well-above normal temperatures felt across the region.
