Warm Temperatures Persist

General Overview: WIDESPREAD RAIN AND THUNDERSTORMS ACROSS THE CENTRAL PLAINS AND MIDWEST THROUGH THE WEEKEND, WITH POTENTIAL FOR HEAVY RAINFALL IN PARTS OF THE NORTHERN PLAINS AND UPPER MIDWEST. SEVERAL LOW PRESSURE SYSTEMS WILL TRACK ACROSS THE COUNTRY, BRINGING PRECIPITATION CHANCES TO MUCH OF THE NATION. ABOVE NORMAL TEMPERATURES EXPECTED FOR MOST AREAS, PARTICULARLY ACROSS THE NORTHERN PLAINS AND PACIFIC NORTHWEST.

EAST:  
A high pressure system will dominate the eastern seaboard initially, providing generally dry conditions for the Northeast and Mid-Atlantic regions through Friday. By Saturday, rain and thunderstorm activity will begin to spread into portions of the Southeast and eventually into the coastal areas. A cold front will push through the region late in the weekend, bringing increased precipitation chances to the eastern seaboard. The Ohio Valley may see scattered thunderstorms developing as frontal boundaries move through the region. By early next week, a new frontal system will approach from the west, bringing additional precipitation chances to the region. Precipitation chances will persist across the southeast late next week, with a drier period returning across the northeast.

Temperature Anomalies:

-Days 1-4: Generally near to slightly above normal temperatures across most of the East, with the warmest anomalies (3-6°F above normal) in the Northeast. Parts of the Great Lakes region may see slightly cooler temperatures by Sunday as a cold front moves through.

-Days 5-8: Continuing above normal temperatures for most areas, though less pronounced than earlier in the period. Most areas will see temperatures 2-4°F above normal.

-Days 9-10: Near normal temperatures return to most of the East, with only slight warm anomalies remaining in parts of the Northeast.

CENTRAL:  
Active weather pattern across the Central US with multiple low pressure systems bringing widespread rain and thunderstorms. The Northern Plains and Upper Midwest will see the most significant precipitation, with rain and thunderstorms spreading across North Dakota, Minnesota, Wisconsin, Iowa, and surrounding areas. Some locations could experience heavy rainfall with potential flooding concerns. A frontal boundary will remain nearly stationary across the Central Plains before shifting eastward through the weekend. By Monday and Tuesday, a new system develops with warm and cold fronts bringing additional precipitation chances across the region. The Central Plains will see thunderstorm activity developing along and ahead of these boundaries. An active pattern may persist across the Central/Southern Plains late next week as multiple disturbances move over the region.

Temperature Anomalies:

-Days 1-4: Above normal temperatures across most of the Central US, with the warmest anomalies (4-8°F above normal) in the Northern Plains. Areas receiving precipitation will see more moderate temperature anomalies.

-Days 5-8: Continued above normal temperatures, particularly across the Northern Plains where anomalies of 4-6°F above normal persist. The Upper Midwest will see temperatures 2-4°F above normal.

-Days 9-10: Warm anomalies begin to diminish but remain 1-3°F above normal across portions of the Northern Plains and Upper Midwest.

WEST:  
Multiple low pressure systems will affect the Western US through the period. The Pacific Northwest will see rain spreading inland from the coast, while the Southwest experiences scattered thunderstorm activity. California will see periods of precipitation, particularly in the northern portions of the state. The Intermountain West will experience scattered thunderstorms developing each afternoon, especially across Nevada, Utah, and portions of Colorado. By early next week, a more organized system will bring increased precipitation chances to the Northern Rockies and Pacific Northwest. High pressure will build into portions of the Southwest by the end of the period, leading to drier conditions there.

Temperature Anomalies:

-Days 1-4: Significantly above normal temperatures across the Pacific Northwest and Northern Rockies, with anomalies of 6-10°F above normal in parts of Idaho, Montana, and Washington. More moderate warm anomalies of 2-5°F above normal for the Southwest.

-Days 5-8: Continued above normal temperatures across most of the West, with the warmest anomalies (4-8°F above normal) persisting in the Pacific Northwest and Northern Rockies.

-Days 9-10: Warm anomalies begin to diminish but remain 2-4°F above normal across portions of the Pacific Northwest and Northern Rockies, with near normal temperatures returning to much of the Southwest.

TROPICAL:
ATLANTIC BASIN: Tropical Storm Gabrielle is approximately 665 miles ENE of the Northern Leeward Islands. Gabrielle is currently moving northwest, with a gradual turn north and eventually northeast expected this weekend and into early next week. Tropical Storm Gabrielle is not expected to impact the United States.
