Weather Underground Forecast for Friday,July 29,2016

A frontal system will bring stormy weather to areas from the Plains to the Mid-Atlantic on Friday, while above normal temperatures persist across the western third of the country.

A low pressure area will trek northeastward from the Mid-Atlantic to the coast of Maine. This system will usher moderate to heavy rain and embedded thunderstorms across the Mid-Atlantic and New England. Scattered showers and thunderstorms will be possible in the southern Mid-Atlantic. Prolonged heavy rain will bring threats of flash flooding to eastern Pennsylvania, New Jersey, southeast New York, Connecticut, Rhode Island and parts of Massachusetts. A cold frontal boundary associated with this system will stretch west southwestward from New England to the southern Plains. This frontal boundary will bring widespread showers and thunderstorms to the Midwest, the Tennessee Valley, the Mississippi Valley, the Plains and the eastern Rockies. Strong thunderstorms will focus over northeast New Mexico, eastern Colorado, Kansas, Oklahoma and northwest Texas.

Meanwhile, a large ridge of high pressure will build over the Great Basin and the Southwest. This high pressure system will keep afternoon temperatures 5 to 15 degrees above normal over many states west of the Continental Divide. The same high pressure system will keep monsoonal moisture in place over the Southwest. Daytime heating will trigger afternoon and evening thunderstorms along favorable terrain. Thunderstorms could form as far north as northern California and southern Oregon.
