Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 355 AM EDT Sat Jun 13 2020 Valid 12Z Sat Jun 13 2020 - 12Z Mon Jun 15 2020 ...Showers and thunderstorms in the Southeast and southern Appalachians, flash flooding possible this weekend... ...Cooler and wet in the Northwest, cooler and dry in the Great Lakes and Northeast, hot and stormy in the Plains... ...Elevated to critical fire risk continues over the Great Basin and Southern Plains, high winds across the Intermountain West... A stalled frontal boundary along the Southeast coast will be responsible for producing a wet weekend with daily episodes of showers and thunderstorms. Rainfall could be heavy at times today with the area most at risk for potential flash flooding stretching from the Florida Panhandle on north to the North Carolina Outer Banks. By Sunday, an upper-level low tracks into the southern Appalachians and a moist southeasterly fetch will develop, forcing rain to develop across the region. Flash flooding is possible there on Sunday in addition to the ongoing flood threat along the Southeast coast. The upper low is forecast to become cut off over the region keeping wet conditions and the potential for flooding into the start of the upcoming week. The eastern and western thirds of the Lower 48 can expect a fairly cool weekend as a pair of cold fronts usher in below normal temperatures. The Northwest can expect not only cool temperatures but also passing showers and a few thunderstorms. Sunday's intermission featuring a few lingering showers ends abruptly as yet another storm system rolls in on Monday. Meanwhile, farther east, the Great Lakes and Northeast is under the influence of a large dome of high pressure throughout the weekend. Abnormally cool temperatures and mostly dry conditions are on tap in these regions into the start of the week. Sandwiched between the cooler air-masses stationed along the coasts of the U.S. are summer-like temperatures over the Plains. High temps should make a run at the mid-upper 90s each afternoon in the Plains. In addition, there will be a chance for thunderstorms each day with the best odds of severe weather occurring in the northern High Plains. The Storm Prediction Center continues to issue Elevated and Critical Risks of fire weather for parts of the Southwest and southern Plains. This is due to the ongoing combination of dry, windy, and hot conditions, which are forecast to continue into Monday. Dry thunderstorms and high winds will also contribute to the risk of fires this weekend. The northern Rockies brace for a windy Saturday as wind gusts could climb as high as 60 miles per hour.
