Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 359 PM EDT Sun Jul 05 2020 Valid 00Z Mon Jul 06 2020 - 00Z Wed Jul 08 2020 ...Severe thunderstorms over the northern Plains through this evening will shift westward into the High Plains on Monday... ...Showers and storms will continue across the Deep South to the Southeast... ...Staying warm/hot in the Upper Midwest to the Great Lakes and across much of Texas... The slow-moving summer weather pattern will start to be more progressive across the northern tier for the start of the work week. A frontal boundary over the northern Plains will continue to act as a focus for showers and thunderstorms for the next couple of days. Some of the thunderstorms may become severe over North and South Dakota into this evening together with flash flooding. The severe weather focus will then shift westward into the northern High Plains on Monday and Tuesday. To the east of this system, a high pressure system will promote very warm temperatures from the Midwest and the Great Lakes eastward into western New England where afternoon temperatures will be well into the upper 80s to low 90s. Over the Northeast, another front will bring slightly cooler than normal temperatures back into coastal areas of ME/NH/MA on Monday. Some showers and a few thunderstorms are expected over Maine into this evening before clearing skies and cooler air arrive on Monday. Scattered showers and thunderstorms are expected to continue near and south of a couple of stationary fronts across the Southeast into the Tennessee Valley. Some locally heavy rain may trigger flash flooding. Over southern Texas, high temperatures are forecast to reach the upper 90s and lower 100s for the next couple of afternoons. Meanwhile, remnant Saharan dust across the Gulf Coast region into Florida is forecast slowly fade away day by day. The primary impacts of the Saharan dust are hazy skies during the day, locally reduced visibility, degraded air quality, and the potential for vividly colorful sunrises and sunsets. Southwesterly flow aloft over the northwestern Nevada will support breezy conditions with low relative humidity values at the surface where the fire danger will remain elevated. Much of the West will remain dry and hot in the interior but cool along the coast. Meanwhile, the next upper-level trough moving in from the Northeast Pacific could trigger some showers and thunderstorms across the interior Pacific Northwest into the northern Rockies, with some rain near the coast later on Monday into Tuesday.
