Flow around this system pulled Gulf moisture in from the south the past few days, and the incoming Hurricane Bill will only aid in pushing moisture over the East Coast. This combination will allow for wet conditions from the Northeast to the Gulf, with heaviest rainfall amounts near 1 inch in the Northeast.
Also expect strong coastal winds and dangerous surf with breaker heights near 7 feet in the Southeast.
Immediately behind this front will see below-normal temperatures, while the Midwest and Plains will return to warm conditions with highs in the 80s. The Ohio and Tennessee Valleys will see highs in the 70s. A strong ridge of high pressure will build in from the Rockies and allow for hot conditions in the Southern Plains with highs near 100.
Meanwhile, out West, a trough of low pressure will push onshore from the the Gulf of Alaska. This will create a cold front over the Pacific Northwest that will kick up cloudy skies.
However, there is little moisture associated with this system, so precipitation is not expected. Mainly, the region will see decreased temperatures on Saturday.
To the south, a trough of low pressure off the coast of California will continue pushing moisture over the Southwest, allowing for monsoonal storms to develop over the deserts.
Temperatures in the Lower 48 states Friday ranged from a low of 35 degrees at Gunnison, Colo. to a high of 111 degrees at Needles, Calif.
