Dry Conditions Continue

General Overview: ACTIVE WEATHER PATTERN ACROSS THE NATION WITH HEAVY RAIN AND THUNDERSTORMS AFFECTING MUCH OF THE CENTRAL PLAINS AND PORTIONS OF THE EAST COAST. A SIGNIFICANT LOW PRESSURE SYSTEM WILL BRING HEAVY RAIN AND POSSIBLE FLASH FLOODING TO THE MID-ATLANTIC REGION THROUGH MIDWEEK. MEANWHILE, WIDESPREAD THUNDERSTORM ACTIVITY WILL PERSIST ACROSS THE CENTRAL PLAINS AND ROCKY MOUNTAIN REGIONS. ABOVE NORMAL TEMPERATURES EXPECTED ACROSS THE NORTHERN PLAINS AND UPPER MIDWEST.

EAST:
A potent low pressure system will impact the Mid-Atlantic region through Wednesday, bringing heavy rain and potential flash flooding to coastal areas from Virginia northward through Delaware and Maryland. The heaviest precipitation is expected Tuesday into Wednesday, with rainfall amounts potentially reaching flooding thresholds in some locations. By midweek, this system will begin to move offshore as high pressure builds in from the north. The Carolinas will see more scattered precipitation, while the Northeast remains largely dry under high pressure influence. As we move toward the weekend, conditions should gradually improve across the region with diminishing precipitation chances. Some rain and thunderstorm activity may return to portions of the coastal Mid-Atlantic by the weekend as moisture flows northward.

Temperature Anomalies:
-Days 1-4: Near normal to slightly below normal temperatures along the immediate East Coast, with slightly cooler conditions in the Carolinas. Most areas will be within 2-3 degrees of seasonal averages.

-Days 5-8: Temperatures trending toward slightly above normal for most of the region, particularly in the interior Northeast. Coastal areas will remain closer to seasonal norms.

-Days 9-10: Continued mild conditions with temperatures generally 2-4 degrees above normal across most of the Eastern Seaboard.

CENTRAL:
An active weather pattern will dominate the Central Plains and Midwest through the forecast period. Widespread rain and thunderstorms will affect areas from the Dakotas southward through Nebraska, Kansas, and into portions of Oklahoma and Texas. A cold front pushing through the region will serve as a focus for thunderstorm development, with the potential for locally heavy rainfall. The North Central states will experience above normal temperatures ahead of this front, with readings potentially 6-10 degrees above seasonal averages in parts of Minnesota and the Dakotas. By midweek, the front will push eastward, bringing precipitation chances to the Great Lakes and Ohio Valley. Another system may affect the region by the weekend, maintaining unsettled conditions across much of the Central Plains.

Temperature Anomalies:
-Days 1-4: Significantly above normal temperatures across the Northern Plains and Upper Midwest, with anomalies of 6-12 degrees above normal. More seasonal conditions prevail in the Southern Plains.

-Days 5-8: Continued above normal temperatures across the Northern Plains, gradually moderating but still 3-6 degrees above normal. Near normal temperatures return to most other areas.

-Days 9-10: Generally mild conditions with temperatures 2-5 degrees above normal across most of the region, particularly in the Northern Plains.

WEST:
A complex weather pattern will affect the Western states, with multiple areas of low pressure bringing precipitation to the Pacific Northwest, Northern Rockies, and portions of the Southwest. Thunderstorm activity will be widespread across the Intermountain West, with a mix of rain at lower elevations and some higher elevation snow possible in parts of Montana and Wyoming. The Southwest will see scattered thunderstorm activity, particularly in Arizona and New Mexico. California will experience varying conditions, with some precipitation possible in northern portions of the state while southern areas remain mostly dry. By late week, precipitation chances increase across the Northwest as another system approaches the coast.

Temperature Anomalies:
-Days 1-4: Above normal temperatures across much of the region, particularly in the Pacific Northwest and Northern Rockies where readings will be 3-6 degrees above seasonal averages.

-Days 5-8: Continued above normal temperatures, especially in the Pacific Northwest and Northern Rockies. Most areas will be 2-5 degrees above normal.

-Days 9-10: Persistent mild conditions with temperatures generally 2-4 degrees above normal across most of the Western states.

TROPICAL:
Post-Tropical Cyclone Mario is noted in the Eastern Pacific off the coast of Mexico. This system is expected to continue weakening and poses no significant threat to the mainland United States.
