Labor Day weekend is just about here, but Mother Nature is still not ready to cooperate. Much of the Northeast and Midwest are going to see multiple areas of low pressure move across the Midwest as well as a stationary front slowly pushing offshore over the Mid-Atlantic. This will fuel rounds of showers and storms as well as increased cloudiness.
On Saturday, temperatures will be around 5 degrees above-average across the regions, which translates to actual highs into the 70s and 80s. A few locations will even get into the 90s. It will also be humid — except in New England — so it’ll feel even hotter thanks to the added moisture. In terms of sky conditions, much of the Midwest and Northeast can expect periods of clouds and sunshine. A complex of thunderstorms will be moving across Iowa early Saturday morning, but those will collapse by the late-morning. Otherwise, the day will be dry in most areas of the Midwest besides a few spotty showers and storms. Unfortunately the Northeast will be more unsettled due to a stationary front draped across the region. Most locations will have the risk for hit or miss showers and storms, especially the Mid-Atlantic. Localized flash flooding is always a possibility this time of year.
On Sunday, high pressure will allow for drier weather to move in across New England and the Mid-Atlantic. Sure, a few spotty showers remain possible, but most areas will be dry with partly cloudy skies. That will be paired with hot and humid conditions — high temperatures will near 90 degrees in the southern Mid-Atlantic region. Now in the Midwest, storms will become a bit more widespread, so cities like Chicago, Des Moines, and Kansas City can all expect storms, especially in the afternoon. Some of these storms will produce heavy rain, which may trigger flash flooding. There is also the risk for this flooding because these storms will be training, or hovering over the same areas for an extended period of time. This is because of this existence of an upper-level setup with high pressure centered over the East Coast, while the Midwest is in the “battle zone” between two different air masses.
On Monday, which is Labor Day, conditions will continue to stay the same for the Northeast. Most areas will be dry, featuring partly cloudy skies, while other locations experience a couple passing showers or thunderstorms. This will be the hottest day out of the weekend ahead of yet another summertime warmup in the middle of next week as temperatures rise into the mid to upper 80s to low 90s. Now in the Midwest, it will be a similar day as Sunday as well, with the same areas at risk for storms. The corridor from Lower Michigan through Iowa and southern Minnesota will feature the greatest storm chances, as clusters of this convection affect the region. Through Monday, some areas in the Midwest will likely receive over 3 inches of rain.
