Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 353 PM EDT Fri Aug 28 2020 Valid 00Z Sat Aug 29 2020 - 00Z Mon Aug 31 2020 ...Remnants of tropical cyclone Laura will track eastward through the lower Ohio Valley and Mid-Atlantic states with heavy rainfall, gusty winds, and severe weather possible Friday night and Saturday... ...Severe storms and flash flooding possible from the Upper Midwest to the Great Lakes late Friday... ...Triple digit heat likely across Texas, with a wildfire threat continuing for parts of the West... Laura is expected to continue weakening and lose its tropical characteristics as it tracks quickly eastward across the lower Ohio valley Friday night night, before crossing the central Appalachians and Mid-Atlantic states on Saturday. The system however will still have the potential to bring periods of heavy rain, strong to severe thunderstorms, and gusty winds to locations along and near its track. Meanwhile, a frontal system moving to the north is expected to produce showers and thunderstorm as it moves across the northern Great Lakes/Upper Midwest Friday night. Some of these storms are expected to become strong to severe and may produce periods of heavy rain. This system is expected to move across the Northeast on Saturday and help move the remnants of Laura out into the western Atlantic by early Sunday. The trailing end of this boundary is expected to stall near the Ozark region and Oklahoma, where it is forecast to help produce showers and thunderstorm through the weekend. Some of the these storms are forecast to become strong to severe and produce periods of heavy rain, resulting in localized flooding concerns. South of the front, above-normal temperatures are expected to persist, with daytime temperatures reaching near or above 100 degrees across much of Texas through the weekend. Heat advisories are in effect across much of Texas, as well as portions of southern Oklahoma and the ArkLaTex region, where heat indices are expected to climb well above 100 -- resulting in dangerous conditions. The potential for showers and thunderstorms is expected to increase through the weekend across portions of Arizona into the lower Colorado Basin. While this will likely bring welcome rains to the dry conditions across the Southwest, these storms may also bring localized flash flooding concerns as well. A cold front is expected to offer little relief to the dry conditions further to the north as it moves across the Pacific Northwest into the northern Rockies, and Northern California on Saturday. Gusty winds, with little to no precipitation, are expected to contribute to elevated to critical fire weather conditions from western Washington and Oregon into the northern Rockies on Saturday.
