An upper level low which has been moving ever so slowly across Tennessee and Georgia is now moving off the East Coast, but one more day of storms will plague the region - the weekend will be much better, however. After a cold last few days in the Northeast, winds will flip around to the southwest this weekend bringing a welcome warmup to places like Pittsburgh, which will see temperatures rise to around 70 this weekend. Even in New England, the weather will warm up considerably.
Out west, Seattle has been well below normal in the temperature department, with highs in the 40s to near 50 with rain. Things should be getting back closer to normal with weekend temps near 60. More details now from Weatherbank, inc....
NATIONAL WEATHER SUMMARY:
Across the East, a weakening low pressure continued to trigger scattered showers and thunderstorms across the Southeast. A few storms in northern Georgia and South Carolina became severe, and produced large hail. Quarter sized hail was reported near Charleston, South Carolina, as well as in Louisville, Georgia. Most stations in these areas recorded rainfall totals less than 0-point-50 inches, but Statesville, North Carolina received slightly more than 1 inch of rain. The only other precipitation recorded in the East was a few light snow snowers in northern New England. For the most part, the Ohio River Valley, Northeast, Great Lakes Region, and Gulf Coast experienced a pleasant and dry day.
A strong ridge of high pressure produced warm and dry conditions across the entire Midwest. The only weather of note is a few occurrences of 40 miles-per-hour or higher wind gusts in the western Dakotas and high temperatures in the 90's in southern Texas.
Much of the western United States also experienced dry and warm conditions under the influence of high pressure. However, a low pressure system centered in southern Idaho did produce scattered showers throughout the northern Rockies, Pacific Northwest, and northern California. Most areas only received light precipitation, but Crescent City, California reported 0-point-99 inches of rainfall. The low pressure system also helped to produce strong winds across parts of southern California, Nevada, and Utah. The strongest wind gust was 69 miles-per-hour recorded in Mojave, California. Hot temperatures were recorded throughout the Desert Southwest with many locations reaching the 90's.
FRONTS IN THE NATION
A cold front lies across west-central Montana, into southeastern Idaho, eastern Nevada, and into southern California.
A cold front lies across the southern tip of Florida.
NATIONAL WEATHER FORECAST
In the East, a low pressure system will continue to produce scattered rain showers and thunderstorms across the Mid-Atlantic, the Tennessee Valley, and parts of the Southeast. The main concern with these storms will be occasional lightning, winds gusting to 45 mph, and brief downpours. Rainfall amounts will stay under a half an inch. There will be a mix of rain and snow across northern locations of New England as an upper-level disturbance will push across the region. Snow accumulations of 1 inch or less can be expected. Otherwise, high pressure will lead to partly cloudy skies and fair conditions across much of the Northeast, the Great Lakes, and the Ohio Valley. Overnight lows will drop into the upper 20s and 30s in the Northeast and the Great Lakes region; into the upper 30s across the Ohio and Tennessee Valleys, and the Mid-Atlantic; into the upper 40s and 50s in the Southeast; and into the 60s in southern Florida.
In the central part of the country, high pressure will be the main weather feature across much of the region. As a result, clear to partly cloudy skies and fair conditions will prevail across the northern, central, and southern Plains, and through the Mississippi Valley. However, there will be areas of patchy fog that will develop across western Nebraska and western Kansas; as well as, southern Texas. Overnight lows will drop into the 30s and lower 40s in the Upper Mississippi Valley and the northern Plains; into the 40s across the central Plains and the Mid-Mississippi Valley; into the 50s through much of the southern Plains; and into the 60s in southern Texas.
In the West, a cold front will continue to swing through the Pacific Northwest and the northern Rocky Mountains, bringing rain showers and mountain snows to the region. Locations above 5000 feet across Idaho and western Montana can expect between 6 and 12 inches of new snow overnight. Otherwise the lower lying regions of the Pacific Northwest will experience mainly rain showers. Rainfall amounts will stay under a half an inch. Skies will be partly cloudy and dry through the rest of the region as high pressure will remain in control. Overnight lows will drop into the 20s and 30s across the Rocky Mountains; into the upper 30s and 40s through the high Plains, the Great Basin, the Pacific Northwest, and northern California; and into the 50s and 60s in the Desert Southwest and southern California.
