Well Below Trend Continues

General Overview: SIGNIFICANT COLD ANOMALIES WILL DOMINATE THE CENTRAL AND EASTERN UNITED STATES THROUGH THE FORECAST PERIOD, WITH TEMPERATURES RUNNING 6-12 DEGREES BELOW NORMAL. MEANWHILE, THE WESTERN STATES WILL EXPERIENCE INCREASINGLY ABOVE-NORMAL TEMPERATURES. PRECIPITATION WILL FOCUS ALONG THE PACIFIC NORTHWEST COAST WITH RAIN AND MOUNTAIN SNOW, WHILE LIGHT SNOW SHOWERS AFFECT THE GREAT LAKES AND NORTHEAST. GULF COAST RAIN WILL DEVELOP LATER IN THE WEEK.

EAST:  Light to moderate snow will slowly exit the Northeast throug today and tonight. On Tuesday and Wednesday, a low pressure system over eastern Canada will bring additional light snow showers to parts of the Great Lakes and Northeast, with some lake effect enhancement possible. Most areas will remain dry but cold as high pressure builds in from the west by Thursday. Along the Southeast coast, some rain may develop offshore but should remain primarily over the Atlantic waters. By Friday, moisture will begin increasing along the Gulf Coast with rain spreading into Florida and potentially parts of the coastal Southeast.

Temperature Anomalies:

-Days 1-3: Significantly below normal temperatures across the entire region, with anomalies of 6-12 degrees below normal, particularly in the Mid-Atlantic and Northeast.

-Days 4-6: Continued below normal temperatures, though moderating slightly in the Southeast. The Northeast and Mid-Atlantic will remain 6-10 degrees below normal.

-Days 7-10: Cold anomalies gradually diminish but remain 3-6 degrees below normal for most areas, with near-normal temperatures possibly returning to parts of the Southeast by day 10.

CENTRAL:  High pressure will dominate the Central Plains through much of the forecast period, bringing generally dry conditions but very cold temperatures. A clipper will slowly shift eastward through midweek, bringing light snow to parts of the Upper Midwest today and tonight. By late week, moisture from the Gulf of Mexico may begin to interact with the southern portion of this front, potentially bringing rain to parts of the South Central region and Texas coast.

Temperature Anomalies:

-Days 1-3: Significant cold anomalies of 8-12 degrees below normal across most of the region, with the coldest readings in the Central Plains and Midwest.

-Days 4-6: Continued below normal temperatures, with anomalies of 6-10 degrees below normal, gradually moderating in the western portions by day 6.

-Days 7-10: Cold anomalies persist but weaken to 3-6 degrees below normal, with near-normal temperatures possibly returning to the western portions of the region by day 10.

WEST:  Multiple high pressure systems will dominate the Western states, bringing generally dry conditions to most areas. However, a series of Pacific systems will bring periods of rain and mountain snow to the Pacific Northwest coast and northern Rockies. The heaviest precipitation will focus along the coastal areas of Washington and Oregon, with mixed precipitation extending inland to Idaho and western Montana. The Southwest will remain largely dry throughout the forecast period with warming temperatures.

Temperature Anomalies:

-Days 1-3: Near normal to slightly below normal temperatures in the Pacific Northwest and Northern Rockies, with slightly above normal temperatures developing in the Southwest.

-Days 4-6: Warming trend continues with above normal temperatures spreading across most of the West, particularly in the interior Northwest and Great Basin where anomalies will reach 3-6 degrees above normal.

-Days 7-10: Significant warming with widespread above normal temperatures of 6-10 degrees, particularly in the Northern Rockies and interior Northwest. Some areas may experience anomalies exceeding 10 degrees above normal.

TROPICAL: No tropical cyclone activity is expected during the next 7 days.
