Near Normal
Temperatures will be near normal across the region today.
General Overview: SIGNIFICANT WINTER WEATHER EXPECTED ACROSS THE NORTHERN TIER WITH FREEZING RAIN AND HEAVY SNOW THREATS. PACIFIC NORTHWEST FACING HEAVY RAIN AND POTENTIAL FLOODING. TEMPERATURE CONTRAST SHARPENS WITH BELOW NORMAL TEMPERATURES IN THE EAST AND CENTRAL REGIONS WHILE THE WEST EXPERIENCES ABOVE NORMAL WARMTH.
EAST:
A high pressure system initially positioned over the Northeast will give way to an approaching low pressure system by Tuesday. Rain will develop across portions of the Southeast and Mid-Atlantic on Monday, with precipitation spreading northward. By Tuesday, a more significant weather system will bring mixed precipitation to much of the region, with freezing rain becoming a major concern for portions of the Northeast and Great Lakes. The potential for ice accumulation will create hazardous travel conditions, particularly across interior sections. As the system evolves, cold air will filter in behind the frontal boundary, transitioning precipitation to snow across northern areas. By Wednesday, a cold front will sweep through the region, bringing colder air and clearing conditions to most areas. The Carolinas will see high pressure building in by midweek, bringing drier conditions.
Temperature Anomalies:
-Days 1-3: Below normal temperatures across most of the region, with departures of 6-12 degrees below normal in the Northeast and Great Lakes. Near normal temperatures along the immediate Southeast coast.
-Days 4-6: Moderating temperatures with near normal readings for most areas, though still slightly below normal in the interior Northeast.
-Days 7-10: Continued below normal temperatures, particularly across the interior, with anomalies of 3-6 degrees below normal. Coastal areas trending closer to seasonal norms.
CENTRAL:
A complex weather pattern will affect the Central regions with multiple systems moving through. Initially, high pressure will provide quiet weather across the southern Plains, while a developing low pressure system brings snow and mixed precipitation to the Northern Plains and Upper Midwest. By Tuesday, this system intensifies with a significant threat of freezing rain developing across portions of the Northern Plains and Upper Midwest. Areas of North Dakota, Minnesota, and Wisconsin face the greatest risk of ice accumulation. Heavy snow is possible north of the freezing rain line. As the system progresses eastward, cold air will filter in behind it, bringing below normal temperatures to much of the region. By late week, conditions gradually improve with high pressure building in from the west.
Temperature Anomalies:
-Days 1-3: Significantly below normal temperatures across the Northern Plains and Upper Midwest with anomalies of 6-12 degrees below normal. Near normal temperatures across the Southern Plains.
-Days 4-6: A sharp temperature gradient develops with continued below normal temperatures in the eastern portions of the region, while western areas moderate toward normal.
-Days 7-10: Below normal temperatures persist across the eastern half of the region, with near to slightly above normal temperatures developing in the western Plains.
WEST:
Active weather will continue across the Pacific Northwest with multiple systems bringing heavy precipitation. The most significant concern is for heavy rainfall and potential flooding across western Washington and Oregon, where flash flooding is possible. Mountain areas will receive heavy snow, particularly across the Cascades and northern Rockies. High pressure over the Southwest will maintain dry conditions across that region. By midweek, another system approaches the Northwest, bringing additional precipitation. The Southwest will remain largely dry and mild throughout the period under high pressure influence. By late week, precipitation chances increase for portions of the northern Rockies as the next system approaches.
Temperature Anomalies:
-Days 1-3: Above normal temperatures across most of the region, particularly in the interior West where anomalies of 6-10 degrees above normal are expected.
-Days 4-6: Continued above normal temperatures, with the warmest anomalies (8-12 degrees above normal) focused on the Great Basin, Rockies, and interior Northwest.
-Days 7-10: Persistent above normal temperatures across the entire region, with the warmest anomalies continuing across the interior West where readings will be 6-12 degrees above normal.
