Remaining Cool Along the Coast and Slightly Warmer Elsewhere

General Overview: ACTIVE WEATHER PATTERN ACROSS THE NATION WITH MULTIPLE SYSTEMS BRINGING RAIN, SNOW, AND MIXED PRECIPITATION. SIGNIFICANT WINTER WEATHER THREATS FOR THE NORTHERN PLAINS AND UPPER MIDWEST WITH FREEZING RAIN POSSIBLE. THUNDERSTORMS DEVELOPING IN THE OHIO VALLEY BY MIDWEEK. TEMPERATURES WELL ABOVE NORMAL FOR CENTRAL US WITH BELOW NORMAL TEMPERATURES EXPANDING IN THE WEST.

EAST:
A high pressure system initially keeps the Eastern US relatively quiet, but significant changes arrive by midweek. Rain will spread across the Northeast and Mid-Atlantic regions by Wednesday as a warm front lifts northward. The Great Lakes region will see a mix of precipitation types, with freezing rain becoming a concern across portions of Michigan and the interior Northeast. By Thursday, rain becomes more widespread across the Ohio Valley and Northeast, with some thunderstorm activity possible. As the system evolves into Friday, an occluded front will bring continued precipitation to the region. The Southeast remains largely dry until later in the week when rain spreads across the Gulf Coast states and into the Carolinas.

Temperature Anomalies:
-Days 1-3: Generally above normal temperatures across the entire Eastern US, with anomalies of 3-6°F above normal. The warmest conditions will be in the Ohio Valley and Great Lakes regions.

-Days 4-6: Continued above normal temperatures, particularly in the Southeast and Mid-Atlantic where anomalies will reach 6-12°F above normal. The warmest conditions will focus on the Carolinas, Georgia, and parts of the Ohio Valley.

-Days 7-10: Cooling trend begins with temperatures returning closer to normal by days 9-10. Some below normal temperatures may develop in the Northeast by the end of the period, while the Southeast maintains slightly above normal readings.

CENTRAL:
The Central US will experience an active weather pattern with multiple low pressure systems affecting the region. Initially, a warm front extends across the Central Plains with rain developing to the north. By Wednesday, a significant system brings mixed precipitation and potential freezing rain to the Northern Plains and Upper Midwest, with heavy snow possible across portions of Minnesota, North Dakota, and South Dakota. This system will be particularly impactful with winter weather hazards. By Thursday, the system shifts eastward with a new low pressure center developing in the Southern Plains, bringing thunderstorms to parts of Missouri and Illinois. Rain will spread northward into the Midwest. By Friday, precipitation continues across much of the Central US with another system beginning to organize in the Southern Plains.

Temperature Anomalies:
-Days 1-3: Significantly above normal temperatures across the entire Central US, with anomalies of 6-15°F above normal. The warmest conditions will be centered on Iowa, Missouri, Nebraska, and Kansas, where temperatures could reach 10-15°F above normal.

-Days 4-6: Continued well above normal temperatures, particularly in the Central and Southern Plains. Anomalies of 8-12°F above normal will be common across the region.

-Days 7-10: Gradual moderation of temperatures with readings returning closer to normal by the end of the period. Some areas in the Northern Plains may see slightly below normal temperatures by day 10.

WEST:
The Western US will see multiple systems bringing precipitation to the region. Snow will be the primary precipitation type in the higher elevations of the Rockies, Cascades, and Sierra Nevada. Rain will affect the Pacific Northwest coast and parts of California. Low pressure systems over the Great Basin and Northern Rockies will bring continued chances for snow across the Intermountain West. By midweek, precipitation becomes more scattered but continues across the mountains. The Southwest remains relatively dry throughout the period. By Friday, another system approaches the Pacific Northwest with renewed precipitation chances.

Temperature Anomalies:
-Days 1-3: Near to slightly below normal temperatures for much of the West, with the coolest readings in the Pacific Northwest where anomalies of 3-6°F below normal are expected.

-Days 4-6: Cooling trend continues with below normal temperatures becoming more widespread. The Northern Rockies and Pacific Northwest will see the coolest conditions with anomalies of 6-12°F below normal.

-Days 7-10: Below normal temperatures persist across the Northern Rockies and Pacific Northwest. The Southwest begins to warm slightly with near to slightly above normal temperatures returning to the region by the end of the period.

TROPICAL:
No tropical cyclone activity is expected during the next 7 days in either the Atlantic or Eastern Pacific basins.
