Scattered Showers and Storms

General Overview: WIDESPREAD RAIN AND THUNDERSTORMS EXPECTED ACROSS MUCH OF THE NATION OVER THE NEXT FEW DAYS, WITH SEVERE THUNDERSTORMS POSSIBLE ACROSS THE CENTRAL PLAINS TODAY. RAIN SHOWERS DEVELOPING IN THE PACIFIC NORTHWEST AND NORTHERN ROCKIES. MULTIPLE FRONTAL SYSTEMS WILL TRACK ACROSS THE COUNTRY, BRINGING CHANGING WEATHER CONDITIONS AND GENERALLY ABOVE-NORMAL TEMPERATURES FOR MOST REGIONS.

EAST:
A frontal boundary will move through the Northeast and Mid-Atlantic regions on Sunday, bringing rain and thunderstorm activity to much of the area. High pressure will briefly build in by Monday, but another system approaches from the west by Tuesday. The Great Lakes region will see periods of rain and thunderstorms as frontal boundaries move through. By midweek, a cold front will sweep across the region, bringing additional precipitation chances. The Southeast will experience scattered thunderstorm activity, particularly along the Gulf Coast and Atlantic seaboard, with rain chances diminishing by late week as high pressure builds offshore.

Temperature Anomalies:
-Days 1-4: Slightly below normal temperatures in parts of the Northeast and Great Lakes early, transitioning to slightly above normal (+2-4°F) for most of the region by day 4.
-Days 5-8: Warming trend continues with above normal temperatures (+3-6°F) spreading across most of the eastern states, particularly in the Mid-Atlantic and parts of the Southeast.
-Days 9-10: Near normal to slightly above normal temperatures (+1-3°F) for most areas, with cooler conditions returning to the Northeast.

CENTRAL:
A complex weather pattern will affect the Central US with multiple systems moving through. Rain and thunderstorms will be widespread across the Midwest and Central Plains on Sunday and Monday. Of particular concern is the potential for severe thunderstorms in Kansas on Monday. Low pressure systems tracking through the region will bring periods of precipitation, with thunderstorm activity gradually shifting southward through midweek. The Mississippi Valley will see periods of rain and thunderstorms as frontal boundaries move through. By late week, a cold front will push through the region, bringing additional precipitation chances before drier conditions return.

Temperature Anomalies:
-Days 1-4: Generally above normal temperatures (+3-6°F) across most of the Central Plains and Midwest, with the warmest anomalies in the northern Plains.
-Days 5-8: Continued above normal temperatures (+2-5°F) for most areas, particularly across the northern Plains and Upper Midwest.
-Days 9-10: Above normal temperatures (+3-6°F) persisting across the northern Plains and Upper Midwest, with near normal conditions returning to the southern Plains.

WEST:
The Pacific Northwest and Northern Rockies will experience mixed precipitation, with rain at lower elevations and potential snow at higher elevations. Multiple areas of low pressure will affect the West Coast, bringing periods of precipitation to Washington, Oregon, and northern California. The Southwest will see scattered thunderstorm activity, particularly in Arizona and parts of Utah and Colorado. High pressure centers over the Intermountain West will bring generally dry conditions to much of the region by midweek, though thunderstorm chances will persist in the mountains. By late week, another system approaches the Pacific Northwest, bringing renewed precipitation chances.

Temperature Anomalies:
-Days 1-4: Above normal temperatures (+4-8°F) across the Pacific Northwest and Northern Rockies, with the warmest anomalies in Idaho and western Montana.
-Days 5-8: Continued above normal temperatures (+3-6°F) across most of the West, with the warmest conditions in the Pacific Northwest and Northern Rockies.
-Days 9-10: Above normal temperatures (+3-6°F) persisting across the northern tier of the West, with near normal conditions in the Southwest.

TROPICAL: 
ATLANTIC BASIN: Tropical Storm Gabrielle is approximately 535 mi SE of Bermuda. Gabrielle is currently moving north-northwest, with a gradual turn north and eventually northeast expected early this week. Tropical Storm Gabrielle is not expected to impact the United States.
