Dry Conditions Prevail

General Overview: ACTIVE WEATHER PATTERN ACROSS THE NATION WITH HEAVY RAIN AND FLASH FLOODING POTENTIAL IN NEW MEXICO AND COLORADO. WIDESPREAD RAIN AND THUNDERSTORMS EXPECTED ACROSS THE NORTHERN PLAINS, ROCKIES, AND PORTIONS OF THE EAST COAST. TROPICAL STORM THIRTEEN-E TRACKING NEAR BAJA CALIFORNIA.

EAST:
A high pressure system will dominate the Mid-Atlantic region through the end of the week, bringing generally dry conditions to much of the Northeast. However, rain and thunderstorm activity is expected along the Southeast coast, particularly along Florida’s eastern shore and extending northward along the coastal Carolinas. By Saturday, a low pressure system will develop offshore, bringing increased precipitation chances to coastal areas. Rain and thunderstorm activity will be most concentrated along the immediate coastline, with interior sections remaining mostly dry. The pattern suggests a frontal boundary will remain offshore but close enough to trigger coastal precipitation.

Temperature Anomalies:
-Days 1-4: Near normal temperatures across most of the Eastern Seaboard, with slightly cooler than normal conditions possible in isolated areas.
-Days 5-8: Gradual warming trend with slightly above normal temperatures spreading across the Northeast and Mid-Atlantic regions, generally 3-6°F above normal.
-Days 9-10: Continued mild conditions with temperatures 3-6°F above normal across much of the region, particularly in the Northeast.

CENTRAL:
The Central United States will experience an active weather pattern with multiple low pressure systems moving through the region. Heavy rain and thunderstorms are forecast across the Northern Plains and Upper Midwest, gradually shifting eastward through the weekend. A particularly concerning area of heavy rain and potential flash flooding is indicated over portions of the Central Plains into the weekend. By Friday and Saturday, a low pressure system will organize over Colorado and New Mexico, bringing widespread precipitation to those areas with heavy rain/flash flooding possible. This system will gradually move northeastward, spreading precipitation into the Upper Midwest by early next week. Multiple frontal boundaries will cross the region, with a warm front extending eastward from the Central Plains by Saturday evening.

Temperature Anomalies:
-Days 1-4: Above normal temperatures developing across the Central Plains and Midwest, with anomalies of 4-8°F above normal, particularly in Iowa, Missouri, and surrounding states.
-Days 5-8: Continued warm conditions with the most significant positive anomalies (6-10°F above normal) focused on the Upper Midwest and Northern Plains.
-Days 9-10: Moderating temperatures with anomalies decreasing to 3-6°F above normal across most of the region.

WEST:
Multiple low pressure systems will affect the Western states, bringing periods of rain, thunderstorms, and mountain mixed precipitation. The southern Rockies will see significant precipitation, with heavy rain and possible flash flooding across New Mexico and southern Colorado. This area of concern will persist through the weekend as a low pressure center becomes established over the region. The Pacific Northwest will also experience periods of precipitation, with rain extending inland from the coast. California will see scattered precipitation chances, primarily in the northern and central portions of the state. By early next week, precipitation will become more scattered across the region as high pressure begins to build.

Temperature Anomalies:
-Days 1-4: Below normal temperatures along the immediate West Coast, particularly in California (3-6°F below normal), with above normal temperatures in the interior West and Northern Rockies.
-Days 5-8: Warming trend with most areas experiencing anomalies up to 2-6°F, with continued mild conditions in the interior West.
-Days 9-10: Generally near normal temperatures across most of the West, with slightly above normal readings (2-4°F) persisting in parts of the Pacific Northwest and California.

TROPICAL:
Tropical Storm Thirteen-E is currently located near the southern Baja California peninsula. The system appears to be tracking northward and may bring increased moisture to portions of the Southwest U.S. later next week.
