Well Above Average Temperatures Continue

General Overview: MULTIPLE WEATHER HAZARDS WILL IMPACT THE NATION OVER THE NEXT SEVERAL DAYS WITH HEAVY SNOW AND MIXED PRECIPITATION THREATS ACROSS THE NORTHERN TIER, HEAVY RAIN AND FLASH FLOODING CONCERNS IN CALIFORNIA, AND FREEZING RAIN POTENTIAL IN THE NORTHERN ROCKIES AND GREAT LAKES. A SIGNIFICANT WINTER STORM WILL DEVELOP LATE IN THE WEEK BRINGING HEAVY SNOW TO THE NORTHERN PORTIONS OF CENTRAL/EASTERN US, WITH MIXED PRECIPITATION FURTHER SOUTH.

EAST: A complex weather pattern will bring multiple precipitation types to the eastern United States over the coming days. Today, an organized storm system will approach from the west, bringing the potential for heavy rain across the Mid-Atlantic and Southeast, with mixed precipitation possible across the interior Northeast and northern Appalachians. The most significant threat will develop Thursday into Friday as a major winter storm impacts the region. Mixed precipitation, including rain, freezing rain, and snow is expected across the Great Lakes, Northeast, Mid-Atlantic, and Ohio Valley, with moderate snowfall is forecast across the northern Great Lakes, and parts of the Northeast. By Saturday, another system will approach the Northeast, bringing additional mixed precipitation and freezing rain threats to the region.

Temperature Anomalies:
-Days 1-3: Near to slightly above normal temperatures across most of the East, with the Northeast experiencing near normal conditions.
-Days 4-6: Above normal temperatures will dominate, with the warmest anomalies across the Southeast and Mid-Atlantic regions.
-Days 7-10: A dramatic shift to below normal temperatures across much of the East, particularly the Northeast and Great Lakes, as Arctic air masses move into the region.

CENTRAL: Mostly dry conditions are expected through the middle of the week with light rainfall possible along the Mississippi Valley. Critical fire weather conditions are forecast across portions of the southern Plains due to dry conditions and strong winds. By Thursday, a larger system will bring accumulating across the Northern Plains and Upper Midwest with mixed precipitation farther south. Additional systems will bring continued rain and snow to the northern Plains and upper Midwest through Friday.

Temperature Anomalies:
-Days 1-3: Well above normal temperatures across the entire Central region, with the most significant warm anomalies across the southern Plains.
-Days 4-6: Continued above normal temperatures, though slightly less extreme than the previous period.
-Days 7-10: A transition to more seasonable temperatures across the northern areas, while the southern Plains maintain above normal conditions.

WEST: Active weather will persist across the western United States with multiple storm systems affecting the region. Heavy rain and flash flooding will be possible across California, particularly in areas with recent burn scars. Heavy snow is forecast for the higher elevations of the Pacific Northwest, northern Rockies, and Sierra Nevada. Mixed precipitation including freezing rain will be possible across portions of the northern Rockies and intermountain West. The Pacific Northwest will see continued rounds of precipitation with heavy snow possible in the mountains and mixed precipitation at lower elevations. Critical fire weather conditions may develop across portions of the Southwest due to dry conditions and gusty winds. Late this week and into the weekend, another significant storm system will impact the region, bringing renewed threats of heavy rain to California and heavy snow to the mountains.

Temperature Anomalies:
-Days 1-3: Above normal temperatures across most of the West, with the most significant warm anomalies across the interior Southwest and Great Basin.
-Days 4-6: Continued above normal temperatures, though more moderate across the Pacific Northwest.
-Days 7-10: A shift toward more seasonable temperatures across the northern areas, while the Southwest maintains above normal conditions.

TROPICAL: No tropical cyclone activity is expected in either the Atlantic or Pacific basins over the next seven days.
