Temperatures Slightly Below Normal

General Overview: ACTIVE WEATHER PATTERN ACROSS THE WESTERN AND NORTHEASTERN US WITH MIXED PRECIPITATION AND POTENTIAL HEAVY SNOW IN THE PACIFIC NORTHWEST AND NORTHERN ROCKIES. RAIN AND THUNDERSTORMS EXPECTED IN SOUTHERN CALIFORNIA AND THE SOUTHWEST. TEMPERATURES WILL BE SIGNIFICANTLY ABOVE NORMAL ACROSS THE CENTRAL AND WESTERN US, WHILE THE SOUTHEAST EXPERIENCES COOLER THAN NORMAL CONDITIONS.

EAST:  A high pressure system will dominate the Southeast through the end of the week, bringing generally dry conditions to much of the region. Light rain is possible across portions of the Northeast and Mid-Atlantic on Thursday and Friday. By Saturday, a developing low pressure system over the Great Lakes will bring more significant precipitation to the Northeast, with rain spreading across the region and potential mixed precipitation including freezing rain in parts of the interior Northeast. The system will continue to impact the region through Sunday, with precipitation gradually tapering off early next week. No severe weather is expected in the eastern states during this period.

Temperature Anomalies:

-Days 1-3: Below normal temperatures across Florida and the Southeast coast (3-6°F below average), with near normal temperatures for the rest of the region.

-Days 4-6: Temperatures trending toward normal across most of the East, with slightly below normal conditions persisting in parts of the Northeast.

-Days 7-10: Temperatures returning to near normal across the entire Eastern region, with slight warming trend by days 9-10.

CENTRAL:  High pressure will keep conditions generally quiet across the Central US through Friday. By Saturday, a developing frontal system will begin to impact the region, with a cold front pushing through the Plains and into the Midwest. This system will bring rain to portions of the Central Plains and Midwest, with some thunderstorm activity possible in the South Central region by Monday. The system will continue to progress eastward through early next week. No significant severe weather or heavy precipitation is expected during this period, though some light to moderate rainfall will occur along and ahead of the frontal boundary.

Temperature Anomalies:

-Days 1-3: Significantly above normal temperatures across the entire Central region, with anomalies of 6-12°F above average, particularly in the Northern Plains and Upper Midwest.

-Days 4-6: Continued warm anomalies across the region, with the warmest temperatures (8-12°F above normal) shifting toward the Central Plains and South Central states.

-Days 7-10: Gradual moderation of temperatures, but still remaining above normal across much of the region, particularly in the South Central states where anomalies of 4-8°F above normal will persist.

WEST:  An active weather pattern will impact the Western US over the next several days. A low pressure system off the Pacific Northwest coast will bring rain, mixed precipitation, and mountain snow to Washington, Oregon, Idaho, and northern California through Friday. Heavy snow is possible in the higher elevations of the Cascades and Northern Rockies. By Friday, another system will bring rain and thunderstorms to Southern California and the Southwest, with potential for heavy rain and flash flooding in some areas. This unsettled pattern will continue through the weekend, with precipitation gradually spreading eastward into the Rockies. By early next week, a new system will develop over Utah and Colorado, bringing additional precipitation to the region.

Temperature Anomalies:

-Days 1-3: Well above normal temperatures across the interior West and Rockies (6-12°F above average), with near normal conditions along the immediate Pacific coast.

-Days 4-6: Continued warm anomalies across most of the region, with the warmest temperatures in the interior West and Northern Rockies.

-Days 7-10: Gradual cooling trend, with temperatures returning closer to normal across much of the region by days 9-10, though still remaining slightly above normal in parts of the Southwest.

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