Above Normal Temperatures

General Overview: ACTIVE WEATHER PATTERN ACROSS THE NATION WITH RAIN AND SNOW IN THE PACIFIC NORTHWEST, MIXED PRECIPITATION IN THE NORTHERN PLAINS, AND DEVELOPING COASTAL SYSTEM ALONG THE EASTERN SEABOARD. TEMPERATURES WILL REMAIN BELOW NORMAL FOR MUCH OF THE EASTERN HALF OF THE COUNTRY WHILE THE WEST EXPERIENCES ABOVE NORMAL CONDITIONS.

EAST:
A low pressure system will develop off the Southeast coast by Friday, bringing snow to coastal areas from the Carolinas northward. By Saturday, this system will intensify and move northeastward along the coast, potentially bringing snow to parts of the Mid-Atlantic. An occluded front will develop as the system matures, with cold air wrapping around the western side of the low. Periods of snow are possible across interior portions of the Northeast and Mid-Atlantic as the system moves through. High pressure will build in by Sunday, bringing drier conditions to most of the region. The coastal low will continue moving offshore, though some lingering precipitation may affect the immediate coastline.

Temperature Anomalies:

-Days 1-3: Significantly below normal temperatures across the entire region, with anomalies of 6-12°F below normal, particularly in the Ohio Valley and Mid-Atlantic states.

-Days 4-6: Continued below normal temperatures, though moderating slightly in the southern portions. Northern areas will remain 6-10°F below normal.

-Days 7-10: Gradual warming trend with temperatures approaching normal in most areas by day 10, though the Northeast will maintain slightly below normal readings.

CENTRAL:
A low pressure system over eastern Texas on Thursday will move eastward, while high pressure builds across the Northern Plains. This will create a boundary where mixed precipitation and some snow will develop across portions of the Northern Plains into the Upper Midwest. By Friday, high pressure will dominate much of the Central Plains, bringing dry conditions. Some light snow or mixed precipitation may affect portions of the Upper Midwest as moisture wraps around the northern edge of the high pressure. By Saturday and Sunday, high pressure will strengthen across the region, leading to generally dry conditions, though some light snow may continue in parts of the Northern Plains.

Temperature Anomalies:

-Days 1-3: Below normal temperatures across most of the region, with anomalies of 6-12°F below normal in the eastern portions, gradually moderating westward.

-Days 4-6: Continued below normal temperatures in the eastern half, with near normal to slightly above normal temperatures developing in the western portions.

-Days 7-10: Warming trend with above normal temperatures spreading eastward, particularly in the Northern Plains where anomalies may reach 6-12°F above normal by day 10.

WEST:
High pressure will dominate the Intermountain West through the period, while a series of Pacific systems bring rain and mountain snow to the Pacific Northwest. These systems will primarily affect Washington and Oregon, with mixed precipitation at higher elevations. By the weekend, precipitation will become more concentrated in the northern portions of the region as high pressure strengthens across the Southwest. The Pacific Northwest will continue to see periods of rain and mountain snow through Sunday, though intensity will likely decrease. Dry conditions will prevail across the Southwest and Great Basin under the influence of high pressure.

Temperature Anomalies:

-Days 1-3: Near normal to slightly above normal temperatures for most areas, with some slightly below normal readings in the Pacific Northwest where precipitation is occurring.

-Days 4-6: Warming trend with above normal temperatures spreading across the entire region, particularly in the Northern Rockies and Intermountain West where anomalies may reach 6-8°F above normal.

-Days 7-10: Significantly above normal temperatures across the entire region, with anomalies of 6-12°F above normal in the Northern Rockies and Northern Plains. Some areas in Montana and Idaho may experience anomalies exceeding 12°F above normal.

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