A stormy weekend is in store for much of the eastern US as an unsettled weather pattern persists across the region while waves of low pressure fuel widespread showers and storms, some of which may pose the risk for flash flooding. This morning, there will be several batches of showers that will affect parts of the Northeast — especially the interior — as well as into the central Appalachian Mountains and various Gulf Coast states. Then as the daytime heating and instability increases by the afternoon, that will allow for additional shower and thunderstorm development. By this point in time, much of the East will be experiencing some kind of wet weather. The only exception will be the Carolina coast while high pressure keeps much of the Midwest dry on Saturday. Sunday will be a quieter day in terms of activity compared to Saturday but it will still be a…

As an upper-level low finally departs from the northeastern US midweek, that will make room for a ridge of high pressure — albeit weak — to creep up the East Coast late-week, allowing for above average temperatures and higher humidity. Some cities in the I-95 corridor, especially from the New York City to Washington, DC areas may even experience a heat wave, which is when temperatures are of at least 90 degrees for 3 consecutive days. Wednesday will be a much drier day across the region with sunshine more present opposed to the clouds and showers. The only exception will be across parts of New England and Upstate New York where a few passing showers and storms will still be possible. Nonetheless, temperatures will be upwards of 2 to 10 degrees above average region-wide, translating to highs in the low to mid 80s inland to the upper 80s and low…

Plumes of African dust, also known as the Saharan Air Layer, have been common not only over the tropical Atlantic Ocean but parts of the United States as well. The pressure patterns over the Northern Hemisphere often steer these Saharan Air Layers westward across the Atlantic Ocean, and in some cases that dust can travel as far west as Texas and Central America. Early this week, dust will return to parts of the southern US, traveling from Texas and Louisiana on Monday to the Mid-Mississippi River Valley by Wednesday, moderating as it moves. Multiple days of dust will likely fill the skies of southeastern Texas and much of Louisiana, making for hazy or filtered blue sunshine and lower air quality, which may be harmful to some.
