Above Normal

General Overview: SIGNIFICANT WINTER WEATHER THREATS ACROSS THE GREAT LAKES AND NORTHEAST WITH HEAVY SNOW AND FREEZING RAIN POSSIBLE THROUGH MIDWEEK. MIXED PRECIPITATION SPREADING ACROSS THE PACIFIC NORTHWEST AND NORTHERN ROCKIES. ABOVE NORMAL TEMPERATURES EXPECTED ACROSS MUCH OF THE CENTRAL AND SOUTHERN PLAINS, WHILE BELOW NORMAL TEMPERATURES AFFECT PORTIONS OF THE NORTHEAST.

EAST:
A developing low pressure system will bring significant winter weather to the Northeast and Great Lakes regions through midweek. Heavy snow is possible across portions of Minnesota, Wisconsin, and Michigan, with freezing rain threats extending into parts of New York and New England. By Tuesday, this system will intensify as it moves eastward, bringing a mix of snow, freezing rain, and rain to the Northeast. The potential for significant ice accumulation exists across portions of the Northeast, particularly in New York and New England. As the week progresses, high pressure will build in from the Atlantic, helping to clear conditions by late week. Some light snow may linger across portions of the Great Lakes region through Thursday.

Temperature Anomalies:
-Days 1-3: Below normal temperatures across the Northeast and parts of the Mid-Atlantic, with readings 6-12°F below normal. Moderating temperatures by day 3 as warmer air begins to push northward.

-Days 4-6: Warming trend begins with temperatures climbing to near or slightly above normal for most of the region. Northern New England may still experience slightly below normal temperatures.

-Days 7-10: Generally near to slightly above normal temperatures across most of the East, with the warmest anomalies (3-6°F above normal) in the Mid-Atlantic states.

CENTRAL:
The Central region will experience a split weather pattern with winter precipitation across the northern portions and warmer, drier conditions to the south. A frontal boundary will move through the Central Plains early in the period, bringing some light precipitation. By midweek, high pressure will dominate much of the region, leading to generally dry conditions. Later in the week, a new system will develop over the Southern Plains, bringing rain and possibly thunderstorms to portions of Texas, Oklahoma, and Arkansas. This system will track northeastward, potentially bringing snow to parts of the Midwest by the weekend.

Temperature Anomalies:
-Days 1-3: Significantly above normal temperatures across the Central and Southern Plains, with anomalies of 6-12°F above normal. Near normal temperatures across the Upper Midwest.

-Days 4-6: Continued warm anomalies expanding across the entire Central region, with the most significant departures (8-12°F above normal) focused on the Mississippi Valley and lower Ohio Valley.

-Days 7-10: Gradual moderation of the warm anomalies, but still remaining above normal for most areas. Northern Plains will see temperatures return closer to seasonal norms by day 10.

WEST:
A series of Pacific systems will bring periods of precipitation to the West Coast and interior West. Mixed precipitation is expected across the Pacific Northwest, Northern Rockies, and portions of the Intermountain West. Snow will fall at higher elevations while rain affects lower elevations and coastal areas. Several areas of low pressure will move through the region during the period, maintaining unsettled conditions. By midweek, high pressure will build over portions of the Southwest, bringing drier conditions to those areas. Critical fire weather conditions are possible in a small portion of New Mexico early in the period.

Temperature Anomalies:
-Days 1-3: Above normal temperatures across much of the West, particularly in the Rockies and Great Basin where anomalies will range from 3-8°F above normal. Near normal temperatures along the immediate Pacific Coast.

-Days 4-6: Continued above normal temperatures for most areas, with the warmest anomalies shifting slightly eastward toward the Central Rockies. Some cooling toward normal along the Pacific Northwest coast.

-Days 7-10: Generally above normal temperatures persisting across the northern Rockies and northern Plains, with anomalies of 3-6°F above normal. Near normal temperatures returning to much of California and the Southwest.

TROPICAL:
The National Hurricane Center indicates no tropical cyclone activity is expected during the next 7 days in either the Atlantic or Eastern Pacific basins.
