Mainly Dry
High and dry conditions prevail outside of the PNW where a passing low continues to bring rain and snow chances.
General Overview: WINTER STORM TO BRING HEAVY SNOW AND MIXED PRECIPITATION TO NORTHERN TIER STATES, WHILE SEVERE THUNDERSTORMS THREATEN THE SOUTHEAST. TEMPERATURES WILL BE WELL ABOVE AVERAGE ACROSS MUCH OF THE CENTRAL AND WESTERN U.S.
EAST: A potent storm system will move through the region, bringing a variety of hazardous weather conditions. Heavy snow is expected across portions of the Northeast and Great Lakes, with accumulations of 6 inches or more possible in some areas. Further south, a mix of snow, sleet, and freezing rain will create treacherous travel conditions. The risk of severe thunderstorms will increase across parts of the Southeast, with damaging winds and isolated tornadoes possible. Heavy rainfall may lead to localized flooding in some areas. As the system moves offshore, strong winds will develop along the coast.
Temperature Anomalies:
-Days 1-3: Near normal to slightly below normal across most of the region, with colder air in place behind the departing storm system.
-Days 4-6: Temperatures trending above normal for much of the area, especially in the Mid-Atlantic and Southeast.
-Days 7-10: Continued above normal temperatures for most areas, with the warmest anomalies in the Southeast.
CENTRAL: A strong cold front will sweep across the region, bringing a sharp temperature contrast and the potential for severe weather. Ahead of the front, warm and humid air will fuel the risk of severe thunderstorms across parts of the Southern Plains and lower Mississippi Valley. Large hail, damaging winds, and a few tornadoes are possible. Behind the front, much colder air will filter in, with snow developing across the Northern Plains and Upper Midwest. Blizzard conditions are possible in some areas due to strong winds and heavy snow.
Temperature Anomalies:
-Days 1-3: Well above normal temperatures ahead of the cold front, followed by a sharp cool down as it passes.
-Days 4-6: Temperatures rebounding to above normal levels for most areas, especially in the Plains.
-Days 7-10: Continued above normal temperatures, with the warmest anomalies shifting westward into the High Plains.
WEST: A series of Pacific storm systems will bring periods of rain and mountain snow to the region. The heaviest precipitation is expected in the Pacific Northwest and Northern Rockies, where several inches of rain and feet of mountain snow are possible. Gusty winds will accompany these systems, potentially creating hazardous travel conditions in some areas. Drier and milder conditions are expected across the Southwest.
Temperature Anomalies:
-Days 1-3: Above normal temperatures for most areas, especially in the interior West.
-Days 4-6: Continued above normal temperatures, with the warmest anomalies in the Great Basin and Rockies.
-Days 7-10: Persistent above normal temperatures, with the warmest anomalies focused over the interior West and Northern Plains.
TROPICAL: No tropical cyclone activity is expected in the Atlantic or Eastern Pacific basins over the next 7 days.
