Well Above Seasonal

General Overview: SIGNIFICANT WINTER STORM AFFECTING THE NORTHEAST WITH HEAVY SNOW AND FREEZING RAIN POTENTIAL THROUGH SATURDAY, WHILE MULTIPLE AREAS OF HIGH PRESSURE DOMINATE THE CENTRAL AND WESTERN REGIONS. TEMPERATURES WILL REMAIN WELL ABOVE NORMAL ACROSS THE EASTERN HALF OF THE COUNTRY INITIALLY, WITH WARMING EXPANDING INTO THE NORTHERN PLAINS AND ROCKIES BY MIDWEEK.

EAST:  A potent low pressure system will bring significant winter weather impacts to the Northeast through today. Accumulating snow will be possible across interior portions of New England and New York, rain showers closer to the coast, and mixed precipitation with freezing rain possible at the freezing line. Further south, rain showers will continue from the Mid-Atlantic to the Deep South, with some strong thunderstorms possible as well for the Deep to Mid South. Sunday and into early next week, this system will push offshore as high pressure builds in from the west, bringing drier conditions for most areas, with snow likely remaining possible for the Northeast and parts of the Mid-Atlantic, and rain lingering along the Atlantic Coast. Another low pressure system will push across Ontario Tuesday and Wednesday, bringing precipitation back to the region with rain and snow possible for much of the Eastern US.

Temperature Anomalies:

-Days 1-3: Well above normal temperatures across most of the region, particularly in the Mid-Atlantic and Northeast where anomalies of 6-12°F above normal are expected. The Southeast will see more moderate warmth of 3-6°F above normal.

-Days 4-6: Temperatures begin to moderate but remain above normal for most areas. The Northeast will cool slightly but still remain 3-6°F above normal, while parts of the Southeast transition to near normal or slightly below normal temperatures.

-Days 7-10: Near normal temperatures return to most of the East, with slightly below normal readings developing across portions of the Southeast and Gulf Coast. The Northeast gradually returns to seasonal norms.

CENTRAL:  High pressure will dominate the Central Plains through the weekend, providing generally dry conditions to most areas. An area of low-pressure may bring light snow to the Upper Midwest on Saturday and into early Sunday, however. Another system may affect the Midwest and North/Central Plains Tuesday and Wednesday, bringing a mix of rain and snow to these areas. The Southern Plains will remain mostly dry.

Temperature Anomalies:

-Days 1-3: Above normal temperatures across most of the region, with the warmest anomalies (6-10°F above normal) in the Ohio Valley and eastern portions. The Upper Midwest will see more moderate warmth.

-Days 4-6: Significant warming trend develops across the Northern Plains and Upper Midwest with temperatures soaring to 10-15°F above normal. The Southern Plains will remain 3-6°F above normal.

-Days 7-10: Continued above normal temperatures across the Northern Plains and Upper Midwest, gradually moderating by day 10. The Southern Plains will see temperatures return closer to seasonal norms with some slightly below normal readings developing in parts of Texas.

WEST:  Multiple areas of high pressure will dominate the Western states, leading to generally dry conditions across much of the region. Light precipitation is expected along the Pacific Northwest coast through the weekend, with rain near the coast and snow at higher elevations. By early next week, a weather system will bring increased precipitation chances to the Pacific Northwest and Northern Rockies, with rain and mountain snow. The Southwest will continue to experience dry conditions with high pressure remaining in place.

Temperature Anomalies:

-Days 1-3: Near to slightly below normal temperatures across the Southwest and parts of the Great Basin, with 3-6°F below normal in parts of Arizona and New Mexico. The Pacific Northwest will see temperatures near normal with some slightly above normal readings.

-Days 4-6: Warming trend develops across the entire region, with temperatures climbing to 3-9°F above normal across the Northern Rockies and Pacific Northwest. The Southwest will transition to near normal or slightly above normal.

-Days 7-10: Continued mild conditions with temperatures generally 3-6°F above normal across most of the West, particularly in the interior Northwest and Northern Rockies. The Southwest will see temperatures closer to seasonal norms.
