It's the Northeast's turn for rain and thunderstorms

Northeast

Weather conditions will go downhill across the Northeast this weekend as a slow-moving frontal system makes its move through the region. Showers and thunderstorms will advance eastward with the front; first into the interior sections of the region and then into New England. Also, with instability increasing well ahead of the cold front and south of the warm front (high temperatures in the 80s along with high humidity), thunderstorms (some strong-to-severe) have a good chance to break out across Maryland, Delaware, eastern Pennsylvania, and New Jersey this afternoon. Not only will these storms contain strong winds and hail but there is also the chance for tornadoes. By Sunday, the front will continue to makes its push eastward towards the coast; still offering the chance of shower and thunderstorms along the 95 corridor. High temperatures on Saturday will range from the cool 50s over much of New England to the mid 80s in the Middle Atlantic region.

 

South

Much of Oklahoma and the northwest Texas had to deal with more severe weather yesterday as three tornadoes were spotted and hail from quarter to baseball-size fell to the ground. The culprit has been a slow-moving storm system that will now not only effect the southern Plains but also advance east through the Lower Mississippi Valley and into the Southeast over the weekend. Today, showers and thunderstorms will spread eastward out of Texas during the day and will stretch from Kentucky, through the Tennessee Valley to the western Gulf Coast by this evening. Rain and thunderstorms will move into the Carolinas, Georgia and northern Florida on Sunday. The rain is actually welcome in many locations due to recent dryness. Atlanta, Ga., Mobile, Ala., and Jackson, Miss. have only seen a trace of rain so far this month. Highs will reach the 80s from the Gulf Coast to the Southeast Coast with 70s across northern sections of the region. As the front makes it move across the region and high pressure builds in, cooler temperatures are in store for early next week.

 

Midwest

Much like the Plains earlier this week, it was the Ohio Valley (from Kentucky to southern Michigan) that was susceptible to severe weather on Friday. Numerous wind and hail reports were received across this outline area. Hail was pea to quarter size while wind gusts were clocked between 30 and 50 mph in cities such as Detroit, Cleveland, Indianapolis, and Dayton. Look for thunderstorms from Ohio to Southeast Missouri while chilly and showery conditions will prevail in the Upper Midwest and northern Great Lakes. One to three inches of rain fell throughout much of Michigan, Ohio, Indiana, and southern Ohio on Friday. With a likely repeat performance today of rain and thunderstorms along the front in the Ohio Valley, the threat of local flooding will increase, especially from southern Indiana to southern Ohio. Chilly northwest winds, cloudy skies, and a few showers will keep highs in the 40s and 50s over much of the Upper Midwest and the Great Lakes. By Sunday, except for some stubborn showers in Wisconsin and Michigan, the storm system that began wreaking havoc in portions of the Plains as early as Tuesday will finally become a memory. Cool, dry high pressure will gain control of much of the region with highs in the 60s in the Plains and Ohio Valley. A warming trend will pick up steam in the plains by early next week.

 

West

Low pressure in the eastern Pacific will push a series of disturbances into the Pacific Northwest this weekend. A weak impulse moved in early this morning squeezing out some precipitation, but a second, stronger impulse will crash into the Pacific Northwest late Saturday into Sunday morning. Meanwhile, look for the warmest temperatures of the season across the Southwest this weekend. Highs in Las Vegas will surge well into the 90s, and Phoenix could reach 100 degrees for the first time this season on Sunday. Warm temperatures in the northern Rockies could lead to rapid snowmelt of recent heavy snow, triggering river flooding into early next week.

Showers and thunderstorms will advance eastward with a frontal sytem today; first into the interior sections of the Northeast and then into New England. Also, with instability increasing well ahead of the cold front and south of the warm front (high temperatures in the low 80s along with high humidity), thunderstorms (some strong-to-severe) have a good chance to break out across Maryland, Delaware, eastern Pennsylvania, and New Jersey this afternoon. Not only will these storms contain strong winds and hail but there is also the chance for tornadoes. The cold front with this storm system is not only impacting the Northeast but also extends southwest through the lower Ohio Valley, into the Tennessee Valley and back towards west Texas.

This morning, this front has been a focus for slow-moving thunderstorms that are lumbering their way along the Ohio River. This is the same area that already experienced heavy rains yesterday afternoon and evening. So the rain occurring this morning may initiate some flooding issues for southern Indiana, southern Ohio, Kentucky, southeastern Missouri, and extreme southern Illinois. Later on this afternoon, this same front will not only continue to trigger rain and thunderstorms but also some scattered strong-to-severe thunderstorms from the Tennessee Valley southwestward back to central Texas.
