NATIONAL WEATHER FORECAST

Today across the East, daytime heating coupled with increased deep tropical moisture, will bring increasing chances for scattered showers and thunderstorms to much of the Deep south and portions of the Southeast by the afternoon hours. No severe weather is expected, but localized areas of heavy rainfall will be possible mainly along the coastline. Further north and east, a warm front extending from the eastern Great Lakes and into the Northeast, will trigger areas of isolated to scattered showers and thunderstorms across the lower Great Lakes and the Northeast, especially during the afternoon hours. Localized rainfall totals of near one inch will be possible in portions of upstate New York and the New England areas. Elsewhere, a broad area of high pressure centered over the Middle Atlantic states, will bring fair and dry conditions to the remainder of the eastern tier of the nation. Afternoon highs will climb into the 50s to mid 80s across the Northeast, Great Lakes, and northern Middle Atlantic; and the 80s and 90s across the Ohio and Tennessee Valleys, the Southeast, and Florida.

Across the central third of the nation, an amplifying upper-level trough pushing across the upper Midwest will produce wide-spread rain showers with embedded thunderstorms to the majority of the upper and middle Mississippi Valleys, and the eastern half of the central and southern Plains. Locally heavy rainfall will be the main threat with this activity, along with a chance for localized flash flooding. High pressure will settle in on the back-side of this system, allowing for clearing skies and fair conditions across the Dakotas and the western half of the central and southern Plains. Highs will reach the mid 50s to lower 70s across the upper Mississippi Valley and northern Plains; the 70s and 80s across the middle Mississippi Valley and central Plains; and the 80s and 90s across the lower Mississippi Valley and southern Plains.

In the West, a weak frontal boundary will trigger rain and mountain snow for the Pacific Northwest and portions of the northern Great Basin. Expect precipitation to be light to moderate with this activity. High pressure will be in place across the remainder of the West, bringing fair skies with dry conditions. Highs will reach the upper 40s to lower 70s across the Rockies and Great Basin; the 70s to upper 80s across the Desert Southwest; the lower 60s to lower 80s across California; and the 50s and 60s across the Pacific Northwest and the Pacific coastline.
