Mainly Dry

 General Overview: WIDESPREAD RAIN AND THUNDERSTORMS ACROSS THE EASTERN THIRD OF THE COUNTRY THROUGH MIDWEEK, WITH ACTIVITY GRADUALLY SHIFTING TO THE SOUTHWEST AND GULF COAST REGIONS BY LATE WEEK. HURRICANE PRISCILLA THREATENS MEXICO WHILE TROPICAL DEPRESSION OCTAVE TRACKS OFFSHORE IN THE EASTERN PACIFIC. TEMPERATURE PATTERN FEATURES SIGNIFICANT ABOVE-NORMAL WARMTH IN THE NORTHEAST EARLY WEEK TRANSITIONING TO ABOVE-NORMAL TEMPERATURES ACROSS THE CENTRAL PLAINS AND NORTHERN TIER BY WEEK’S END.

 EAST:
A significant weather system will bring widespread rain and thunderstorms to much of the Eastern Seaboard through Wednesday. High pressure over the Great Lakes will gradually give way as a cold front pushes through the region. The Northeast will experience above-normal temperatures initially, with readings 6-12 degrees above average, particularly across New England. Rain and thunderstorm activity will be concentrated along the Atlantic coast from the Mid-Atlantic through the Southeast and Gulf Coast states. 

By Thursday, the precipitation will shift southward, focusing primarily on the Southeast coast and Florida, as high pressure builds in from the north. The weekend looks to bring drier conditions across most of the region as the frontal boundary pushes offshore. Some coastal showers may linger along parts of the Eastern Seaboard by Sunday.

Temperature Anomalies:
-Days 1-3: Significantly below normal temperatures (6-12°F below average) across the Northeast and Mid-Atlantic, gradually building.
-Days 4-6: Near normal to slightly below normal temperatures for most areas as high pressure builds in.
-Days 7-10: Gradual warming trend with temperatures returning to slightly above normal (2-4°F) across most of the region.

 CENTRAL:
The Central United States will experience a changing weather pattern through the week. Initially, high pressure will dominate across the Great Lakes and Upper Midwest, providing relatively calm conditions. By midweek, a frontal boundary will push through the region, bringing rain and thunderstorm chances to portions of the Central Plains and Midwest. 

As the week progresses, the focus for precipitation will shift southward into the Southern Plains and Gulf Coast. Kansas and surrounding areas may see thunderstorm development by Thursday into Friday. The weekend will feature a developing area of low pressure in the Northern Plains that will introduce cooler air to the Upper Midwest while warmer air builds across the Central and Southern Plains.

Temperature Anomalies:
-Days 1-3: Near normal temperatures for most areas, with slightly above normal readings in the Southern Plains.
-Days 4-6: Warming trend developing across the Central Plains with temperatures climbing 6-10°F above normal, particularly in Nebraska, Kansas, and surrounding states.
-Days 7-10: Continued above normal temperatures (6-10°F) across the Central Plains extending northward into the Northern Plains and Upper Midwest.

 WEST:
The Western United States will see an active weather pattern with multiple areas of low pressure affecting the Pacific Northwest and Northern Rockies. Rain and mixed precipitation will be common across Washington and Oregon, with mountain snow possible at higher elevations. The Southwest will experience scattered thunderstorm activity across Arizona, New Mexico, and portions of Utah and Colorado.

By midweek, high pressure will build across the Great Basin and Southwest, bringing drier conditions to much of the region. However, another system will approach the Pacific Northwest by the weekend, bringing renewed precipitation chances to the coastal areas and northern Rockies. California will remain mostly dry throughout the period with only isolated precipitation chances.

Temperature Anomalies:
-Days 1-3: Near normal temperatures for most areas with some slightly below normal readings in the Pacific Northwest.
-Days 4-6: Cooling trend for the Pacific Northwest and Northern Rockies with temperatures 3-6°F below normal, while the Southwest remains near to slightly above normal.
-Days 7-10: Below normal temperatures continuing across the Pacific Northwest and parts of California (3-6°F below average), with near to slightly above normal temperatures across the interior Southwest.

 TROPICAL:
Atlantic Basin: Tropical storm Jerry has formed about 950 miles ESE of the northern Leeward Islands with maximum sustained winds of 50 mph. This system is anticipated to develop into a Hurricane in the next 24-48 hours and will likely bring some impacts throughout the Caribbean, including the US Virgin Islands but is expected to recurved into the Atlantic this weekend with no significant impacts expected to the mainland US at this time. 

Eastern Pacific Basin: Hurricane Priscilla is located off the western coast of Mexico and poses a threat to the Mexican coastline. Additionally, Tropical Depression Octave is tracking offshore in the Eastern Pacific. Neither system is expected to directly impact the continental United States, but moisture from these systems may enhance precipitation across portions of the Southwest and Gulf Coast later in the week. Finally, an area of low pressure south of the Mexican coast could develop into the next system in the coming days. Chances are medium within 48 hours at 60% and high through the next 7 days at 80%.
