Temperature Split Across The Region

General Overview: WINTER STORM SYSTEM TO BRING MIXED PRECIPITATION TO NORTHEAST AND GREAT LAKES THROUGH MIDWEEK, FOLLOWED BY COLD FRONT PUSHING THROUGH CENTRAL US. ABOVE NORMAL TEMPERATURES ACROSS NORTHERN PLAINS AND ROCKIES WILL GRADUALLY SHIFT EASTWARD AS PATTERN CHANGES THROUGH THE WEEKEND.

EAST:
A significant winter weather system will impact the Northeast and Great Lakes regions through Wednesday evening. Mixed precipitation including snow, rain, and freezing rain will spread across much of New England, the Mid-Atlantic, and eastern Great Lakes. Several low pressure systems tracking along the East Coast will maintain this precipitation pattern through midweek. By Thursday, the system will begin moving offshore, with precipitation gradually ending from west to east.

As we move into Friday and the weekend, a cold front will push through the region, bringing cooler air to the Southeast and Mid-Atlantic states. Florida will continue to see rain and possibly thunderstorms through midweek before conditions improve. By the weekend, high pressure will build in across much of the eastern seaboard, leading to drier conditions.

Temperature Anomalies:
-Days 1-3: Near to slightly above normal temperatures for the Northeast and Mid-Atlantic, with below normal temperatures developing across the Southeast by day 3.
-Days 4-6: Below normal temperatures spreading across most of the East, particularly across the Southeast and Mid-Atlantic regions, with Florida seeing temperatures 4-6°F below normal.
-Days 7-10: Continued below normal temperatures for most eastern areas, gradually moderating by day 10 with warming temperatures beginning to return to the Southeast.

CENTRAL:
High pressure will dominate the Central Plains initially, with generally dry conditions prevailing. By Thursday, a cold front will push through the Northern Plains and Upper Midwest, bringing mixed precipitation to Minnesota, Wisconsin, and the Dakotas. This front will continue southward through the weekend, potentially bringing rain and some snow to portions of the Central Plains and Midwest.

By Friday into Saturday, a developing low pressure system in the Great Lakes will bring precipitation to parts of the Midwest. The Mississippi Valley will remain largely dry through the period, though some light precipitation may develop in the Tennessee Valley by the weekend.

Temperature Anomalies:
-Days 1-3: Significantly above normal temperatures across the Northern Plains and Upper Midwest, with anomalies of 6-12°F above normal.
-Days 4-6: Cooling trend begins as the cold front pushes through, with near normal temperatures returning to the Upper Midwest and below normal temperatures developing in the Central Plains.
-Days 7-10: Below normal temperatures spreading across much of the Central region, particularly the Upper Midwest and Great Lakes, while warming returns to the Southern Plains by day 10 with temperatures 6-8°F above normal in Texas and Oklahoma.

WEST:
High pressure will dominate much of the Western United States through the period, with generally dry conditions prevailing across the Southwest, Great Basin, and Rockies. Some light precipitation may affect the Pacific Northwest and Northern Rockies at times, but significant precipitation is not expected.

By the weekend, a developing low pressure system in Colorado may bring some precipitation to portions of the Central Rockies. The West Coast will remain largely dry under the influence of high pressure, though some light precipitation may affect coastal areas of the Pacific Northwest.

Temperature Anomalies:
-Days 1-3: Above normal temperatures across most of the West, particularly across the Northern Rockies and High Plains where temperatures will be 6-12°F above normal.
-Days 4-6: Continued above normal temperatures for most western areas, though slightly moderating from the peak warmth of the early week.
-Days 7-10: Above normal temperatures persisting across the Southwest and Rockies, with some cooling spreading into the Northern Rockies and Pacific Northwest by day 10.

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