Near to Slightly Above Average Temperatures Today

General Overview: ACTIVE WEATHER PATTERN ACROSS THE NATION WITH MIXED PRECIPITATION IN THE NORTHWEST AND NORTHERN ROCKIES, RAIN AND THUNDERSTORMS ACROSS THE CENTRAL PLAINS AND MIDWEST, AND POTENTIAL FLASH FLOODING IN PARTS OF MISSOURI AND ARKANSAS. TEMPERATURES WILL REMAIN SIGNIFICANTLY ABOVE NORMAL ACROSS THE SOUTH CENTRAL STATES THROUGH THE PERIOD.

EAST:  A high pressure system will dominate much of the eastern seaboard initially, providing generally dry conditions for the first day or two. The interior northwest will see continued wintry precipitation, however. By midweek, a developing low pressure system will approach from the west, bringing rain to portions of the Ohio Valley and Mid-Atlantic regions. By the late week, a new low pressure system will bring returning chbances to the Mid-Atlantic and Northeast as it passes to the north. 

Temperature Anomalies:

-Days 1-3: Near normal to slightly below normal temperatures across much of the Northeast and Mid-Atlantic, with slightly cooler conditions developing across the Great Lakes region.

-Days 4-6: Warming trend begins with above normal temperatures spreading across the Southeast and Mid-Atlantic, with anomalies of 4-8°F above normal, particularly across the Carolinas, Virginia, and West Virginia.

-Days 7-10: Moderating temperatures with generally near normal to slightly above normal conditions (1-3°F above normal) across most of the region, with the warmest anomalies remaining in the Southeast.

CENTRAL:  Initially, a frontal boundary extending from the Northern Plains to the Mid Mississippi Valley will bring rain and thunderstorms, with potential for heavy rainfall and flash flooding across portions of Missouri and Arkansas. As this system moves eastward, a new low pressure system develops over Oklahoma/Texas by Thursday, bringing additional rain and thunderstorms to the Southern Plains and lower Mississippi Valley. Thunderstorm activity could become strong at times across eastern Texas, Oklahoma, and Arkansas. By late week, another system approaches from the west, bringing additional precipitation chances to southern portions of the region.

Temperature Anomalies:

-Days 1-3: Significantly above normal temperatures across the Southern Plains and South Central states, with anomalies of 6-12°F above normal, particularly across Oklahoma and Texas.

-Days 4-6: Continued very warm conditions with temperature anomalies peaking at 8-12°F above normal across Arkansas, Oklahoma, and surrounding areas. The warm anomaly expands northward into the Central Plains.

-Days 7-10: Gradual moderation of temperatures with anomalies decreasing to 2-5°F above normal across most of the region by the end of the period.

WEST:  Multiple low pressure systems will affect the Western states, bringing periods of precipitation to the region. Mixed precipitation is expected across the Northwest, Northern Rockies, and Intermountain West, with snow at higher elevations and rain at lower elevations. The Southwest will see scattered rain and thunderstorm activity, particularly across Arizona and southern portions of Utah and Colorado. By the laet week, a new low pressure system develops over New Mexico, which could enhance precipitation across the Southwest before moving eastward.

Temperature Anomalies:

-Days 1-3: Generally above normal temperatures across much of the West, particularly the Rockies and Intermountain regions with anomalies of 3-6°F above normal. Near normal temperatures along the immediate Pacific Coast.

-Days 4-6: Continued mild conditions with above normal temperatures persisting across most of the region, though slightly cooler air begins to filter into the Pacific Northwest.

-Days 7-10: Temperatures trend closer to normal across most of the region, with slight below normal readings possible in parts of the Pacific Northwest by the end of the period.

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