Morning Rain

General Overview: ACTIVE WEATHER PATTERN ACROSS THE NATION WITH MIXED PRECIPITATION IN THE NORTHERN PLAINS AND PACIFIC NORTHWEST, RAIN ACROSS PORTIONS OF THE NORTHEAST AND SOUTHEAST, AND THUNDERSTORMS DEVELOPING ALONG THE GULF COAST. HURRICANE MELISSA CONTINUES IN THE WESTERN ATLANTIC. TEMPERATURE CONTRASTS WILL BE SIGNIFICANT WITH BELOW NORMAL TEMPERATURES IN THE SOUTHEAST AND ABOVE NORMAL CONDITIONS BUILDING ACROSS THE WESTERN STATES.

EAST:
A low pressure system off the Northeast coast will bring rain to portions of New England and the Mid-Atlantic through Friday, along with increase winds. High pressure builds in for the weekend, bringing drier conditions to much of the region. By Saturday, a frontal boundary will approach from the west, bringing rain to portions of the Tennessee Valley and Southeast. Rain will spread across the coastal regions of the Carolinas and Virginia by Sunday into Monday. The Ohio Valley and Great Lakes will see generally dry conditions after initial precipitation clears on Friday. By early next week, high pressure will dominate the eastern seaboard, leading to clearing skies and diminishing precipitation chances.

Temperature Anomalies:
-Days 1-3: Below normal temperatures across much of the Southeast and Mid-Atlantic, with readings 3-6°F below average. Near normal temperatures for New England.
-Days 4-6: Moderating temperatures with near normal readings for most areas, though slightly below normal conditions persist in parts of the Southeast and Gulf Coast.
-Days 7-10: Gradual warming trend with temperatures returning to near normal or slightly above normal across most of the region by days 9-10, particularly in the Northeast and Mid-Atlantic.

CENTRAL:
Mixed precipitation will affect portions of the Northern Plains and Upper Midwest on Friday, with rain and possibly some snow in the Dakotas and Minnesota. High pressure builds across the Central Plains by Saturday, bringing drier conditions. A frontal boundary will move through the region Saturday into Sunday, with rain developing across portions of the Mississippi Valley and extending into eastern Texas and Louisiana. Thunderstorms are possible along the Gulf Coast, particularly in eastern Texas and Louisiana on Saturday. By Sunday into Monday, a new low pressure system develops in the Northern Plains, bringing another round of precipitation to the region. The Central Plains will remain generally dry under high pressure influence through much of the period.

Temperature Anomalies:
-Days 1-3: Below normal temperatures across much of the region, particularly in the South Central states where readings will be 3-6°F below average.
-Days 4-6: Warming trend begins with temperatures returning to near normal for most areas, though some below normal readings persist in parts of the Mississippi Valley.
-Days 7-10: Above normal temperatures build across the Plains, with readings 3-6°F above average, particularly in the Northern Plains and Upper Midwest by the end of the period.

WEST:
Multiple areas of low pressure will affect the Pacific Northwest and Northern Rockies through the weekend, bringing rain to coastal areas and mixed precipitation to higher elevations. The Southwest will remain generally dry under the influence of high pressure. By Saturday, high pressure builds across the Great Basin and Rocky Mountain regions, leading to drier conditions. Rain and mountain snow will continue intermittently across the Pacific Northwest through the period. The Southwest will see warming temperatures under persistent high pressure, with dry conditions prevailing across California, Nevada, and Arizona.

Temperature Anomalies:
-Days 1-3: Above normal temperatures across much of the Southwest, with readings 3-6°F above average. Near normal temperatures for the Pacific Northwest.
-Days 4-6: Warming trend continues with above normal temperatures expanding across the entire Western region, particularly in the Great Basin and Rocky Mountains where readings will be 6-9°F above average.
-Days 7-10: Persistent above normal temperatures across the entire Western region, with the warmest anomalies (6-9°F above average) centered over the Rocky Mountain states and Northern Plains.

TROPICAL:
Hurricane Melissa is currently located in the western Atlantic Ocean, well offshore of the U.S. East Coast. The system is expected to remain over open waters and poses no direct threat to the U.S. mainland. No additional tropical cyclone development is expected in either the Atlantic or Eastern Pacific basins during the next 7 days.
