Above Average for Most, Near to Below Average in the Pacific Northwest

General Overview: ACTIVE WEATHER PATTERN BRINGS RAIN, SNOW, AND SEVERE STORMS TO MUCH OF THE NATION OVER THE NEXT FEW DAYS. TEMPERATURES WILL BE WELL ABOVE AVERAGE FOR MOST AREAS EAST OF THE ROCKIES.

EAST:  Rain showers will linger across south and central areas today and tomorrow, with a few thunderstorms possible. A potent storm system will bring widespread precipitation to the region Tuesday and into the late week. Rain and thunderstorms are expected across the Southeast and Mid-Atlantic, with some storms potentially becoming severe. Further north, a wintry mix of snow, sleet, and freezing rain is likely across parts of the Northeast and Great Lakes. As the system moves through, temperatures will rise well above average, especially in the Ohio Valley and Northeast.

Temperature Anomalies:

-Days 1-3: Well above average, with anomalies of 6-12°F above normal for most areas.

-Days 4-6: Continuing above average for most, but cooling trend begins in the Northeast.

-Days 7-10: Near to slightly above average for most areas, with cooler air pushing into the Northeast.

CENTRAL:  Dry weather will be seen for most areas today and tomorrow outside scattered rain and thunderstorms along the Gulf Coast and lower Mississippi Valley. A dynamic weather pattern will bring multiple rounds of precipitation to the region. A new area of low-pressure will bring a wintry mix to parts of the Northern Plains and Upper Midwest Tuesday and Wednesday, while rain and thunderstorms are expected further south. There is a risk of severe weather in the Southern Plains and lower Mississippi Valley. Behind this system, expect a drier period late in the week for most areas, although the Northern Plains and Upper Midwest will see continued rain and snow chances.

Temperature Anomalies:

-Days 1-3: Significantly above average, with anomalies of 8-15°F above normal for many areas.

-Days 4-6: Continuing well above average for most, but cooling trend begins in the Northern Plains.

-Days 7-10: Gradual cooling trend, but still above average for many areas. Near normal temperatures return to the Northern Plains and Upper Midwest.

WEST:  A series of storm systems will bring rain and mountain snow from the Pacific Northwest to Northern Rockies through the much of the upcoming week. Increasing precipitation chances will be seen across the Four Corners on Tuesday as a new area of low-pressure transitions into the Central US. Dry weather will then return for most areas through the remainder of the week, with rain and mountain snow continuing across the northern fringes.

Temperature Anomalies:

-Days 1-3: Near to slightly above average for most areas, with the warmest anomalies in the Southwest.

-Days 4-6: Warming trend continues, with above-average temperatures spreading across most of the region.

-Days 7-10: Well above average temperatures persist, especially in the Southwest and Great Basin.

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