NATIONAL WEATHER SUMMARY:

Across the East, showers and thunderstorms erupted during the afternoon hours over the Southeast, Carolinas, and over the Gulf Coast along a stationary front. A few thunderstorms were severe, with hail and damaging winds. Funnel clouds were reported over Wilmington, North Carolina and Fort Pierce, Florida. Rainfall amounts over an inch were reported. Skies were generally clear and dry over the Northeast, Great Lakes, Ohio Valley, and Appalachians.

In the central region, heavy rainfall was recorded along the Texas and Louisiana Gulf Coasts as Hurricane Humberto moved toward the coast. Several locations recorded over 2 inches of rainfall. Further to the north, skies were generally sunny and dry as high pressure dominated the Midwest and Great Plains. Gusty winds were reported over the Dakotas as a low pressure system strengthened in the region. Record low temperatures were observed during the morning hours in Grand Forks, North Dakota, and International Falls, Minnesota.

Over the West, afternoon showers and thunderstorms developed over the southern Rockies and Four Corners region. No severe weather was reported, and rainfall amounts were light. The storms slowly progressed eastward into the high Plains. Gusty winds were recorded in Montana as a system moved through the area. Skies were fair and dry over the Great Basin, California, Desert Southwest, Pacific Northwest, and northern and central Rockies.

NATIONAL WEATHER FORECAST

In the East, a stationary front will produce scattered showers and thunderstorms across the Carolinas, the Southeast, and Florida. A few strong thunderstorms, along with rainfall amounts of a half of an inch will be possible with this activity. Otherwise, high pressure will allow for mostly sunny to partly cloudy skies and dry conditions throughout the Great Lakes region, the Northeast, the Ohio and Tennessee Valleys, and much of the Mid-Atlantic region. High temperatures will reach into the 60s and 70s across the Great Lakes region, the Ohio Valley, and the Northeast; and into the 80s and the lower 90s through the Tennessee Valley, the Mid-Atlantic region, the Southeast, and Florida.

Across the central part of the country, Tropical Storm Humberto will continue to produce very heavy rainfall, strong winds, and embedded thunderstorms along the western Gulf Coast, eastern TX, and into portions of the Lower Mississippi Valley. Rainfall amounts of five to ten inches, with locally heavier amounts will be possible and will cause wide-spread flooding. Winds gusting to 50 miles-per-hour, isolated weak tornadoes, and occasional lightning will also be possible with this activity. Further north, a low pressure system will bring scattered showers and thunderstorms to the Upper Mississippi Valley. A few strong thunderstorms, along with rainfall amounts of a half of an inch will be possible. Otherwise, fair skies and dry conditions will prevail throughout much of the Plains and the Middle Mississippi Valley. High temperatures will reach into the 50s and 60s across the northern Plains; into the upper 60s to the lower 80s through the central Plains, and the Upper and Middle Mississippi Valley; and into the 80s and 90s across the southern Plains and the Lower Mississippi Valley.

In the West, an upper-level disturbance will bring in the chance for showers and thunderstorms to portions of the Pacific Northwest and far northern California. No severe weather is expected, and rainfall amounts will remain light. Otherwise, expect mostly sunny to partly cloudy skies and dry conditions throughout the high Plains, the Rocky Mountains, the Desert Southwest, the Great Basin, and much of California. High temperatures will reach into the 50s and 60s across the northern high Plains; into the 60s and lower 70s along the coastal regions of both the Pacific Northwest and California; into the mid 70s to the lower 90s through the high Plains, the Rocky Mountains, the Great Basin, much of interior California, and much of the Pacific Northwest; and into the mid 90s to near 110 through the Desert Southwest and southeastern California.
