Weekend Weather Preview

By WeatherBug Meteorologist, Alyssa Robinette
Stalled fronts and plenty of tropical and monsoonal moisture will be in store throughout the U.S. this weekend. Most places west of the Mississippi will also have to battle extreme heat.
Saturday
A cold front will push across the Eastern U.S. on Saturday, while the western fringes of the cold front remaining stalled over the Deep South and southern Plains. To complicate things further, a deep surge of tropical moisture will be funneled into the region.
Rain showers and thunderstorms will be found throughout the Eastern Seaboard, best chance in the afternoon and evening. There will also be a good chance for rain and thunderstorms along the Gulf Coast and parts of the southern Plains.
Given the surge of tropical moisture, there will be the potential for heavy rain and flooding, especially in urban, low-lying and other more flood prone areas. Remember, it is always best to “Turn Around, Don’t Drown!” if you approach a flooded roadway. There will also be the potential for strong winds within thunderstorms across the East on Saturday, especially across the Carolinas and Mid-Atlantic.
A second cold front will drop south across the north-central U.S. for the start of the weekend. Rain showers and thunderstorms will be likely along the front during the afternoon and evening. Thunderstorms here could be strong to severe, containing damaging winds and large hail. Localized heavy rain and flooding will also be possible.
A strong upper-level ridge of high pressure will build over the West. While this will bring unseasonably hot temperatures, it also allows the monsoon pattern to start up again. Showers and thunderstorms will be likely from the Great Basin into the Rockies and Front Range during the afternoon and evening.
Only a limited number of areas stay dry on Saturday. This would be the immediate West Coast as well as the Midwest and Great Lakes.
Temperatures will peak in the 70s and 80s across the Upper Mississippi Valley, Midwest, Great Lakes, Appalachia and most of the Northeast. Expect 90s and 100s for the rest of the U.S., including the western two-thirds of the U.S. as well as the Deep South, Southeast and Mid-Atlantic. However, the immediate West Coast and the tallest peaks in the Mountain West could only see temperatures rise into the 70s and 80s. There will also be several highs in the 110s in the Desert Southwest and the southern Plains.
Sunday
It will be a “rinse and repeat” in terms of the weather on Sunday. A cold front will be stalled along the East Coast into the Deep South and south-central U.S., with tropical moisture streaming into the East. Meanwhile, the other cold front remains draped over the north-central U.S. High pressure continues to pump heat and monsoonal moisture into the West.
Rain and thunderstorms will be likely throughout the Eastern U.S. for the end of the weekend. Heavy to very heavy rain could still be concern, which could lead to localized flooding.
There will also be rain and thunderstorm chances across the northern Plains, Upper Mississippi Valley Great Lakes and Midwest. Here, be on the lookout for strong to severe thunderstorms, with the possibility of high winds and large hail.
The Great Basin, Rockies and Front Range will also be looking at rain and thunderstorms chances. The best chance would occur in the afternoon.
Like Saturday, most of the West Coast should remain dry under high pressure.
High temperatures will be in the 70s, 80s and lower 90s for the northern Plains, Upper Mississippi Valley and Great Lakes along with the entire Eastern Seaboard. Nineties and 100s will be widespread for the rest of the nation. Though, the immediate West Coast and higher elevations could only see the mercury jump into the 70s and 80s. Highs in the 110s are possible again in the Desert Southwest.
