NATIONAL WEATHER SUMMARY

Yesterday across the East, a few afternoon thunderstorms affected portions of southern Florida, bringing brief heavy rainfall and gusty winds. Miami, Florida received 2-point-44 inches of rainfall, and other locations across southern Florida reported about a quarter of an inch of rainfall. The remainder of the East was under a strong ridge of high pressure, bringing fair skies with dry conditions. Highs across the Northeast reached the upper 60's to lower 80's, and highs across the Tennessee Valley were in the lower to mid 80's. Highs across the Southeast were in the upper 70's to upper 80's, and highs across the Middle Atlantic reached the lower 70's to lower 80's. Highs across the Ohio Valley were in the 70's, and highs across the Great Lakes region reached the upper 60's to lower 70's.

Across the central third of the nation, a storm system over the upper Mississippi Valley will trigger thunderstorms for the upper and middle Mississippi Valley and the southern Plains. A few of these storms became severe, containing gusty winds of up to 60 miles-per-hour. Dime sized hail and winds of 60 miles-per-hour were reported near Council Grove, Kansas. Two tornadoes touched down in portions of Iowa as well; one near Sully, Iowa, which had an 8 mile damage path, and one near Malcolm, Iowa. Otherwise, fair skies with dry conditions were reported across the northern and central Plains and the lower Mississippi Valley as high pressure remained in control of the weather pattern. Highs across the upper Mississippi Valley were in the lower 60's to mid 70's, and highs across the middle Mississippi Valley reached the lower 70's to lower 80's. Highs across the lower Mississippi Valley were in the 80's, and highs across the southern Plains were in the lower 80's to lower 90's. Highs across the central Plains reached the 80's, and highs across the northern Plains were in the mid 70's to mid 80's.

In the West, a weak frontal boundary over the Pacific Northwest triggered rain showers for the Pacific Northwest and northern California. Mountain snow was observed across these regions as well, but no significant accumulation was noted. Rainfall totals were generally light as well, with some of the totals including:

Location Rainfall (inches)

Bremerton, WA 1.32

Quillayute, WA 0.89

Astoria, OR 0.79

Aurora, OR 0.72

Fair skies with dry conditions were observed across the remainder of the western United States, bringing fair skies with dry conditions to the region. Highs across the Rockies were in the lower 50's to lower 80's, and highs across the Great Basin reached the lower 50's to lower 90's. Highs across the Desert Southwest were in the upper 70's to upper 80's, and highs across the Pacific Northwest reached the upper 50's to lower 60's. Highs across California were in the mid 60's to lower 80's.

NATIONAL WEATHER FORECAST

In the East, a low pressure system will produce cloudy skies with showers and thunderstorms across the Great Lakes region and portions of the Ohio Valley. No severe weather is expected; however, rainfall amounts of a half of an inch will be possible. Elsewhere, partly cloudy skies with the chance for scattered showers and thunderstorms can be expected across Florida. A few strong thunderstorms, along with rainfall amounts of up to an inch will be possible with this activity. Otherwise, high pressure will allow for fair skies and dry conditions throughout the Northeast, the Mid-Atlantic region, the Tennessee Valley, and the Southeast. High temperatures will reach into the 60s and 70s across the Great Lakes region, the Ohio Valley, and the Northeast; and into the 80s through the Tennessee Valley, the Mid-Atlantic region, the Southeast, and Florida.

Across the central part of the country, expect mostly cloudy skies with the chance for light rain showers across the Upper Mississippi Valley as a low pressure system exits the region. Elsewhere, partly cloudy skies and the chance for afternoon and evening showers and thunderstorms can be expected across the central and southern Plains, and the Lower Mississippi Valley. The strongest storms will be capable of producing frequent lightning, strong winds, sizable hail, and brief downpours. Rainfall amounts of a quarter of an inch will be possible. Otherwise, high pressure will allow for fair skies and dry conditions across the northern Plains and the Middle Mississippi Valley. High temperatures will reach into the 60s and 70s through the Upper Mississippi Valley; and into the 80s and 90s across the Plains region, and the Middle and Lower Mississippi Valley.

In the West, an upper-level trough will bring the chance for showers and thunderstorms to the central and southern high Plains, the Rocky Mountain region, the Desert Southwest, and the Great Basin. A few strong thunderstorms will be capable of producing dangerous lightning, gusty winds, small hail, and heavy downpours. Rainfall amounts of up to a half of an inch will be possible. Elsewhere, a low pressure system will continue to produce rain showers and high elevation snows across the Pacific Northwest and northern California. Any rainfall or snowfall amounts will be light. Otherwise, fair skies and dry conditions will prevail. High temperatures will reach into the 50s and 60s across the Pacific Northwest and the northern Rocky Mountains; and into the 70s and 80s through the central and southern high Plains, the central and southern Rocky Mountains, the Great Basin, and California.
