Slightly Cooler Today

General Overview: ACTIVE WEATHER PATTERN ACROSS THE NATION WITH MULTIPLE SYSTEMS BRINGING PRECIPITATION TO MANY REGIONS. HEAVY RAIN AND THUNDERSTORMS EXPECTED ACROSS THE GULF COAST AND SOUTHEAST, WHILE MIXED PRECIPITATION AND POSSIBLE FREEZING RAIN AFFECTS PORTIONS OF THE NORTHEAST. SIGNIFICANT SNOW CONTINUES ACROSS THE PACIFIC NORTHWEST AND NORTHERN ROCKIES. MUCH ABOVE NORMAL TEMPERATURES DOMINATE THE CENTRAL AND SOUTHERN PLAINS.

EAST:
A complex weather pattern will affect the Eastern U.S. over the next several days. Initially, high pressure will provide relatively quiet conditions across much of the region. By Monday into Tuesday, a developing low pressure system will bring rain to the Southeast and Mid-Atlantic, with mixed precipitation and potential freezing rain developing across portions of Pennsylvania and the Northeast. The freezing rain threat will be most significant Monday into Tuesday, creating hazardous travel conditions. By midweek, precipitation will shift eastward as the system moves offshore. The Ohio Valley and Great Lakes will see periods of rain and snow as frontal boundaries move through the region. Along the Gulf Coast, rain and thunderstorms will be prevalent, especially during the first part of the forecast period.

Temperature Anomalies:
-Days 1-3: Near normal to slightly above normal temperatures for most areas, with cooler conditions in northern New England.
-Days 4-6: Warming trend with temperatures climbing to 3-6°F above normal for most of the region, particularly across the Mid-Atlantic and Southeast.
-Days 7-10: Continued above normal temperatures for the Southeast and Mid-Atlantic, with a return to near normal or slightly below normal conditions in the Northeast by day 10.

CENTRAL:
The Central U.S. will experience significant temperature contrasts as multiple systems move through the region. A low pressure system tracking across the Northern Plains will bring rain and thunderstorms to portions of the Mississippi Valley and South Central regions. Rain and thunderstorm activity will be most widespread across Arkansas, Louisiana, and eastern Texas, with some storms potentially becoming strong. As the week progresses, a new system will develop in the Plains, bringing precipitation to the Upper Midwest and Great Lakes. The Central Plains will remain largely dry under the influence of high pressure, though frontal boundaries will occasionally bring precipitation chances to portions of the region.

Temperature Anomalies:
-Days 1-3: Significantly above normal temperatures across the entire region, with anomalies of 6-12°F above normal in the Central and Southern Plains.
-Days 4-6: Continued well above normal temperatures expanding eastward, with the warmest anomalies (10-15°F above normal) centered over Oklahoma, Kansas, and Missouri.
-Days 7-10: Gradual moderation of the warm anomalies, though temperatures remain 3-8°F above normal across most of the region.

WEST:
Active weather will continue across the Western U.S., particularly in the Pacific Northwest and Northern Rockies. Multiple low pressure systems will bring periods of rain and mountain snow to Washington, Oregon, Idaho, and western Montana. Heavy rain with potential flash flooding is possible along the California coast. The Southwest will experience drier conditions under high pressure influence, though precipitation will occasionally spread into portions of Nevada and Utah. By midweek, a new system will bring additional precipitation to the Pacific Northwest and Northern Rockies. Snow levels will fluctuate but generally remain low enough for significant mountain snow accumulations, with some snow possible at lower elevations in Idaho and Montana.

Temperature Anomalies:
-Days 1-3: Above normal temperatures for most areas, particularly across the interior West where anomalies will reach 6-10°F above normal.
-Days 4-6: Continued warm anomalies across most of the region, with the warmest conditions in the interior West and Rocky Mountain states.
-Days 7-10: Slight cooling trend but still generally above normal, with the warmest anomalies shifting toward the Northern Rockies and Northern Plains.

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