Above Normal Temperatures Expected

General Overview: ACTIVE WEATHER PATTERN ACROSS THE NATION WITH SIGNIFICANT PRECIPITATION EXPECTED IN THE PACIFIC NORTHWEST AND NORTHERN ROCKIES. MIXED PRECIPITATION AND POTENTIAL FREEZING RAIN ACROSS PORTIONS OF THE GREAT LAKES AND UPPER MIDWEST. RAIN AND THUNDERSTORMS ALONG THE GULF COAST. TEMPERATURE CONTRAST WILL BE SHARP WITH BELOW NORMAL TEMPERATURES IN THE MIDWEST AND NORTHEAST WHILE THE WESTERN US EXPERIENCES WELL ABOVE NORMAL CONDITIONS.

EAST:
A cold front will move offshore during Sunday, bringing high pressure to much of the Eastern Seaboard. By Monday, high pressure will dominate the Southeast while a new frontal system approaches from the west. Rain will develop along coastal areas of the Carolinas and Georgia. As the week progresses, precipitation will spread northward along the coast. The Great Lakes region will see mixed precipitation with potential freezing rain, particularly by Tuesday into Wednesday. This could create hazardous travel conditions across portions of Michigan and the Upper Great Lakes. By Thursday, a more organized system will bring rain to much of the Eastern Seaboard with potential thunderstorms developing along the Gulf Coast of Florida.

Temperature Anomalies:
-Days 1-3: Below normal temperatures across most of the region, with departures of 6-12 degrees below normal in the Mid-Atlantic and Northeast. Near normal temperatures along the immediate Southeast coast.

-Days 4-6: Moderating temperatures with near normal conditions returning to most areas. Slight below normal temperatures persist in coastal areas of the Northeast.

-Days 7-10: Warming trend with above normal temperatures spreading across most of the region, particularly in the Ohio Valley and Mid-Atlantic where temperatures will rise to 3-6 degrees above normal.

CENTRAL:
High pressure will initially dominate the Central Plains, but a developing frontal boundary will bring precipitation chances to the Northern Plains and Upper Midwest by Monday. Mixed precipitation will be possible across portions of the Dakotas and Minnesota, with potential freezing rain in some locations. By Tuesday, a cold front will push through the region, bringing rain to portions of the Central Plains. As the week progresses, a more significant storm system will develop in the Northern Rockies and move into the Plains, bringing widespread precipitation. Thunderstorms may develop across portions of Texas and the lower Mississippi Valley by midweek. The Gulf Coast will see periods of rain and thunderstorms throughout the forecast period.

Temperature Anomalies:
-Days 1-3: Significantly below normal temperatures across the Midwest and Northern Plains, with departures of 8-12 degrees below normal. Near normal temperatures in the Southern Plains.

-Days 4-6: Warming trend begins with temperatures returning to near normal across most areas. Above normal temperatures developing in the Southern Plains.

-Days 7-10: Well above normal temperatures spreading across the entire region, with departures of 6-12 degrees above normal in the Southern Plains and lower Mississippi Valley. Particularly warm conditions developing in Oklahoma, Arkansas, and Texas.

WEST:
An active weather pattern will bring significant precipitation to the Pacific Northwest and Northern Rockies. Rain and thunderstorms are expected along the Washington and Oregon coasts, with heavy rain possible at times. Mixed precipitation will occur in the interior Northwest and Northern Rockies. Multiple high pressure systems will dominate the Southwest, keeping conditions generally dry there. By Monday, precipitation will intensify across the Pacific Northwest with potential for heavy rainfall and flash flooding along coastal areas. As the week progresses, a new system will bring additional precipitation to the region with snow in the higher elevations of the Cascades and Northern Rockies. By Wednesday, a developing low pressure system in the Northern Rockies will bring more widespread precipitation to the region.

Temperature Anomalies:
-Days 1-3: Well above normal temperatures across the entire Western US, with departures of 6-12 degrees above normal in the Rockies and Great Basin. Particularly warm conditions in Idaho, Wyoming, and Colorado.

-Days 4-6: Continued above normal temperatures across most of the region, with the warmest anomalies shifting slightly eastward. Temperatures 8-12 degrees above normal in the Central Rockies.

-Days 7-10: Persistent above normal temperatures, particularly in the Southwest and Southern Rockies where departures will remain 6-10 degrees above normal. Some moderation in the Pacific Northwest with near normal temperatures returning to Washington and Oregon.

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