The nations weather

Another round of rainy weather is anticipated in Lower Great Lakes, Northeast and the Mid-Atlantic Thursday as the lingering low in the Ohio Valley finally lifts northeastward.

Bands of heavy rain and thunderstorms will move through the already saturated areas of northeastern Pennsylvania and central New York through the day. Rainfall of 1 to 2 inches will be possible.

Areas experiencing prolonged showers and storms may have heavier amounts of rainfall. Excessive precipitation in these regions will translate into more localized flooding and chances of flash flooding.

Meanwhile, the Mid-Atlantic will also see some showers and periods of heavy rain as a cold front approaches the coast. This rain may result in some flooding along the coast.

To the south, rain and thunderstorms will persist in the central and eastern Gulf Coast as frontal boundary remains nearly stationary over the area.

Behind this activity, another low pressure system will clip the Upper Great Lakes, bringing chances of showers and thunderstorms to northern Minnesota and Wisconsin. An associated cold front will sweep through the Upper Great Lakes as this system progresses with strong and gusty northwest winds and a cooler airmass. This will allow the region to experience more autumn-like temperatures through the weekend.

In the West, high pressure will provide another day of unseasonably warm weather to the Intermountain West and Pacific Northwest. Meanwhile, low pressure will approach the California coast with cooler conditions and increased clouds at the end of the week.

Temperatures in the Lower 48 states Wednesday have ranged from a morning low of 26 degrees at Angel Fire, N.M., to a high of 102 degrees at Houston/Dunn Helistop, Texas.
