We’re tracking a new area of low pressure that will move through the Ohio River Valley and the Mid-Atlantic from now through Tuesday, bringing new rounds of rain to some areas. This is the same low pressure that was responsible for the severe thunderstorms on Friday and Saturday.
This Sunday, showers and thunderstorms will move to the northeast, from portions of the Central Plains to the eastern Ohio River Valley. Due to added moisture from the Gulf of Mexico and Caribbean Sea, some localized, tropical downpours can be expected. There is also the risk for severe storms with damaging winds and hail in the Ohio Valley. Farther south, we’re tracking a cold front moving across Texas. Scattered showers and storms will shift into a line of strong to severe storms as they move into eastern Texas. The main risk with these storms will be damaging winds and flash flooding before they subside Sunday night. A different storm system will bring scattered showers and thunderstorms to the Northeast, but much of the precipitation will dissipate as they reach the coast from the north and west.
Then on Monday, we’ll see a steady area of rain moving into parts of the Great Lakes region, tracking from west to east. Cities like Chicago and Detroit can expect several hours of rain to begin the new week. Most of this rain will be rather light, however. Overnight Monday, periods of rain are expected across the interior Northeast and in northern New England. A line of strong thunderstorms may also develop across the eastern Ohio Valley.
By Tuesday, the weak low pressure will reach the Mid-Atlantic coast. This will bring light rain showers to much of New England and parts of the northern Mid-Atlantic region. Much of this rain will clear out by the early-afternoon, but it may stick around for a bit longer across Upstate New York and northern New England.
Overall, drier weather is expected for the remainder of the week across the Northeast. The next chance for rain will be during the Memorial Day Weekend while rain returns on either Thursday or Friday to the Midwest.
