Dry Weather Expected

General Overview: ACTIVE WEATHER PATTERN ACROSS THE NATION WITH HEAVY RAIN AND FLASH FLOODING THREATS IN CALIFORNIA, FREEZING RAIN POTENTIAL IN THE NORTHEAST AND UPPER MIDWEST, AND MIXED PRECIPITATION ACROSS THE PACIFIC NORTHWEST AND NORTHERN ROCKIES. TEMPERATURES WILL REMAIN SIGNIFICANTLY ABOVE NORMAL ACROSS THE CENTRAL US THROUGH CHRISTMAS.

EAST:  A complex weather pattern will affect the Northeast and Mid-Atlantic regions over the next several days. Initially, rain will spread across portions of the Ohio Valley and into the Northeast. By Thursday, rain and light freezing rain will become possible for parts of Pennsylvania, New York, and portions of New England. A more potent system will bring precipitation of all types to the Great Lakes and into the Northeast late Thursday and through Friday. By the weekend, precipitation will transition to a more rain-dominated pattern for most of the region as temperatures moderate, although a mix of precipitation types will beset the Northeast. The Southeast will experience generally quiet conditions with high pressure dominating, though some rain may develop along the coastal areas by the weekend. The Mid-Atlantic states will see periods of rain through midweek before drier conditions return.

Temperature Anomalies:

-Days 1-3: Near normal to slightly below normal temperatures across New England and the Northeast, with slightly above normal temperatures for the Southeast.

-Days 4-6: A cooling trend develops with below normal temperatures spreading across much of the Eastern Seaboard, particularly in the Northeast and Mid-Atlantic regions.

-Days 7-10: Below normal temperatures continue across most of the East, with the coldest anomalies focused on the Carolinas and Virginia, gradually moderating by day 10.

CENTRAL:  A frontal boundary will move through the region mid this week, bringing chances for rain, snow, and freezing rain to the Northern Plains and Midwest. As the week progresses, a new system will develop in the Central Plains, bringing precipitation chances to the region. Friday, additional light precipitation may develop for the Northern Plains and Upper Midwest. This weekend, snow chances persist across the Upper Midwest, with rain showers expected along the middle/lower Mississippi Valley. The South Central region will remain largely dry with above normal temperatures through the period.

Temperature Anomalies:

-Days 1-3: Significantly above normal temperatures across the entire Central region, with the warmest anomalies (10-12°F above normal) centered on Oklahoma, Kansas, Missouri, and Arkansas.

-Days 4-6: Continued well above normal temperatures across the Central and South Central regions, gradually moderating by day 6 as cooler air begins to infiltrate from the north.

-Days 7-10: A transition to below normal temperatures across the eastern portions of the Central region, while the western portions maintain above normal readings.

WEST:  An active pattern will bring significant precipitation to the Western states. California faces a serious threat of heavy rain and potential flash flooding, particularly along the coastal areas. The heaviest precipitation is expected Wednesday through Thursday, with flash flood concerns highest in southern California. The Pacific Northwest and Northern Rockies will see a mix of rain, snow, and mixed precipitation. Mountain areas will receive significant snowfall, while lower elevations experience rain or a wintry mix. By late week, another system approaches the West Coast, bringing renewed precipitation chances to the region.

Temperature Anomalies:

-Days 1-3: Above normal temperatures across most of the West, particularly in the interior Southwest and Rockies.

-Days 4-6: Temperatures remain above normal for most areas, though cooling begins in the Pacific Northwest with some below normal readings developing in Washington and Oregon.

-Days 7-10: A more variable temperature pattern develops with continued above normal temperatures in the Southwest and Rockies, while near to slightly below normal temperatures affect the Pacific Northwest.

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