Scattered Showers and Storms

General Overview: ACTIVE WEATHER PATTERN ACROSS THE NATION WITH MULTIPLE SYSTEMS BRINGING RAIN, SNOW, AND MIXED PRECIPITATION. POTENTIAL FOR HEAVY SNOW IN PARTS OF THE NORTHERN PLAINS AND UPPER MIDWEST. RAIN AND THUNDERSTORMS EXPECTED ACROSS THE SOUTH CENTRAL REGIONS. BELOW NORMAL TEMPERATURES WILL DOMINATE THE CENTRAL U.S. WHILE THE SOUTHWEST EXPERIENCES ABOVE NORMAL TEMPERATURES.

EAST: Today, rain and snow will spread across the Great Lakes and eventually into the Northeast overnight, with areas of Pennsylvania, New York, and parts of New England seeing a wintry mix. By Sunday, precipitation will expand across more of the Eastern Seaboard with rain along the coast and a mix of rain and snow inland. A new low-pressure system will move northeast across the Eastern US Monday and Tuesday, bringing precipitation across much of the region. The Mid-Atlantic and Southeast will see primarily rain, with some thunderstorm activity possible along the Gulf Coast of Florida. Snow will likely become possible across the Great Lakes and into the Northeast. Conditions dry out behind the system on Wednesday.

Temperature Anomalies:

-Days 1-3: Below normal temperatures across much of the region, particularly in the Northeast and Mid-Atlantic, with anomalies of 3-6 degrees below normal. The Southeast will experience near normal to slightly below normal temperatures.

-Days 4-6: Continued below normal temperatures across the region, with the coldest anomalies (4-8 degrees below normal) in the interior Northeast and Great Lakes. Coastal areas will moderate somewhat.

-Days 7-10: Gradual moderation with temperatures trending closer to normal, though still generally 2-4 degrees below normal across much of the region.

CENTRAL:  A developing low pressure system will bring multiple precipitation types across the region. Heavy snow is possible across portions of the Midwest, with some areas potentially seeing significant accumulations. Rain and thunderstorms will spread across Oklahoma, Arkansas, and Texas, with the heaviest rainfall expected in eastern Texas and Louisiana. As the system progresses eastward, cold air will filter in behind it, bringing below normal temperatures and drier conditions to much of the region. By early next week, another system may bring additional precipitation to parts of the Central and Southern Plains.

Temperature Anomalies:

-Days 1-3: Significantly below normal temperatures across the Northern and Central Plains into the Midwest, with anomalies of 6-12 degrees below normal. The Southern Plains will see near normal to slightly below normal temperatures.

-Days 4-6: Continued below normal temperatures, particularly across the Midwest and Great Lakes, with anomalies of 6-10 degrees below normal. Cold air will spread further south into the Southern Plains.

-Days 7-10: Gradual moderation but still below normal across much of the region, with the coldest anomalies remaining in the Upper Midwest and Great Lakes.

WEST: Multiple areas of low pressure will bring periods of precipitation to the Pacific Northwest and Northern Rockies, with mixed precipitation including snow at higher elevations. The Southwest will remain relatively dry with above normal temperatures. By Sunday, precipitation will spread into parts of Utah and Colorado with snow likely at higher elevations. The Pacific Northwest will continue to see periods of rain and mountain snow. California will remain mostly dry with near normal temperatures along the coast and above normal temperatures inland. As the pattern evolves, additional systems may bring precipitation to the Northwest and Northern Rockies, while the Southwest remains generally dry and mild.

Temperature Anomalies:

-Days 1-3: Above normal temperatures across much of the Southwest and Southern Rockies, with anomalies of 3-6 degrees above normal. The Pacific Northwest and Northern Rockies will see near normal to slightly below normal temperatures.

-Days 4-6: Continued above normal temperatures in the Southwest, with near normal temperatures elsewhere. Some cooling in the Pacific Northwest.

-Days 7-10: Warming trend across much of the West, particularly in the interior West and Southwest, with anomalies of 3-6 degrees above normal. The Pacific Northwest will see temperatures closer to normal.

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