Above Average Temperatures

General Overview: SIGNIFICANT WINTER WEATHER EXPECTED ACROSS THE NORTHERN ROCKIES AND NORTHERN PLAINS WITH FREEZING RAIN AND HEAVY SNOW POSSIBLE. MIXED PRECIPITATION WILL AFFECT PORTIONS OF THE NORTHEAST THROUGH MIDWEEK. TEMPERATURES WILL REMAIN WELL ABOVE NORMAL ACROSS THE WESTERN STATES WHILE BELOW NORMAL TEMPERATURES SPREAD ACROSS THE CENTRAL AND EASTERN REGIONS LATER THIS WEEK.

EAST:
A frontal system will bring mixed precipitation to the Northeast through Wednesday, with areas of freezing rain possible across portions of New England and the interior Northeast. Rain will be the primary precipitation type along the coastal regions. By Thursday, high pressure builds in across the Southeast, bringing drier conditions to much of the eastern seaboard. A new low pressure system develops along the Southeast coast by Friday, potentially bringing rain to coastal areas. The weekend looks generally quieter with some lingering precipitation possible in the Mid-Atlantic region. Temperatures will start near normal but trend cooler as the week progresses.

Temperature Anomalies:
-Days 1-3: Near to slightly below normal temperatures across the Northeast and Mid-Atlantic, with readings 2-6°F below normal. The Southeast will experience near normal temperatures.

-Days 4-6: Cooling trend continues with temperatures dropping to 4-8°F below normal across much of the region, particularly in the Great Lakes and interior Northeast.

-Days 7-10: Moderating temperatures with near normal readings returning to most areas by day 10, though some below normal temperatures persist in the Northeast.

CENTRAL:
A significant winter weather event will unfold across the Northern Plains and Upper Midwest through Thursday. Freezing rain and heavy snow are possible across portions of the Dakotas and Minnesota, creating hazardous travel conditions. A low pressure system developing in the Central Plains by Thursday will bring a mix of precipitation types to the region. As this system moves eastward, colder air will filter in behind it, transitioning rain to snow in some locations. By the weekend, high pressure builds in across the southern portions of the region, bringing drier conditions, while another system may affect the northern areas by Sunday.

Temperature Anomalies:
-Days 1-3: Near normal temperatures across most areas, with slightly below normal readings in the northern portions.

-Days 4-6: Significant cooling trend with temperatures plummeting to 8-12°F below normal across the Northern Plains and Upper Midwest. The cold anomaly spreads southward through this period.

-Days 7-10: Cold anomalies persist across the northern and central portions, gradually moderating by day 10. Southern areas return to near normal.

WEST:
Multiple high pressure systems will dominate the Southwest through midweek, while a series of frontal systems affect the Pacific Northwest and Northern Rockies. Heavy rain is possible along the Washington and Oregon coasts, with heavy snow and potential freezing rain across the higher elevations of the Northern Rockies, particularly in Montana and Idaho. By Thursday, precipitation chances decrease across much of the region as high pressure strengthens. The weekend looks generally dry for most areas, though some precipitation may return to the Pacific Northwest by Sunday. The most significant weather hazard will be the heavy snow potential across the mountainous terrain.

Temperature Anomalies:
-Days 1-3: Significantly above normal temperatures across the entire Western region, with anomalies of 6-12°F above normal, particularly in the interior West and Rockies.

-Days 4-6: Continued warm anomalies with temperatures remaining 6-12°F above normal across most of the region, especially pronounced in the Rocky Mountain states.

-Days 7-10: Persistent warmth with temperatures 6-12°F above normal across the entire region, with the warmest anomalies centered over the Rocky Mountain states and Great Basin.

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