Still Dry

General Overview: ACTIVE WEATHER PATTERN ACROSS THE NATION WITH RAIN AND MIXED PRECIPITATION AFFECTING THE PACIFIC NORTHWEST, NORTHERN ROCKIES, AND PORTIONS OF THE EASTERN SEABOARD. TEMPERATURES WILL REMAIN ABOVE NORMAL ACROSS MUCH OF THE WESTERN STATES WHILE COOLER CONDITIONS PERSIST IN THE SOUTHEAST THROUGH EARLY WEEK.

EAST:  A low pressure system off the Atlantic coast will bring rain and thunderstorms to portions of the Southeast and Mid-Atlantic regions through Monday. Areas from Florida through the Carolinas and into the coastal Northeast will experience periods of rainfall, with some thunderstorm activity possible along the immediate coast. By Tuesday, high pressure builds in across the Southeast, bringing drier conditions. However, by midweek, a new frontal boundary approaches from the west, with a developing low pressure system bringing another round of precipitation to the Northeast. The Great Lakes region will see periods of rain and possibly some mixed precipitation as colder air filters in from Canada.

Temperature Anomalies:

-Days 1-3: Below normal temperatures across much of the Southeast and Gulf Coast, with readings 3-6°F below average. Near normal temperatures for the Northeast and Mid-Atlantic.

-Days 4-6: Temperatures trending closer to normal across most of the region, with slightly below normal conditions persisting along the immediate East Coast.

-Days 7-10: A cooling trend develops with below normal temperatures spreading across the eastern seaboard, particularly from the Mid-Atlantic through New England, with anomalies of 3-6°F below normal by days 9-10.

CENTRAL:  High pressure will dominate the central portions of the country early in the period, providing generally dry conditions across the Plains and Midwest. By Tuesday, a developing low pressure system in the Northern Plains will bring a chance for precipitation across portions of the Upper Midwest. As this system moves eastward, a cold front will sweep through the region by midweek, potentially bringing rain to portions of the Midwest. The Southern Plains will remain largely dry throughout the period. By late week, another frontal boundary approaches from the northwest, bringing additional precipitation chances to the Northern Plains and Upper Midwest.

Temperature Anomalies:

-Days 1-3: Near normal temperatures across most of the region, with slightly cooler than normal conditions in the lower Mississippi Valley.

-Days 4-6: Warming trend develops with above normal temperatures spreading across the Plains, particularly in the Central and Northern Plains where anomalies may reach 4-8°F above normal.

-Days 7-10: Continued above normal temperatures across much of the Plains, gradually moderating by day 10 with near normal conditions returning to the Midwest.

WEST:  An active weather pattern will persist across the Pacific Northwest and Northern Rockies, with multiple systems bringing rain and mixed precipitation to these regions. The first system affects Washington, Oregon, Idaho, and western Montana through Monday, with areas of rain at lower elevations and mixed precipitation at higher elevations. High pressure over the Southwest will keep conditions dry across California, Nevada, and Arizona initially. By midweek, another system approaches the Pacific Northwest, bringing additional precipitation to the region. The Northern Rockies will continue to see periods of rain and mountain snow throughout the period. The Southwest will remain largely dry with above normal temperatures.

Temperature Anomalies:

-Days 1-3: Above normal temperatures across much of the West, particularly in the Southwest and Great Basin where anomalies will range from 6-10°F above normal. Near normal temperatures along the immediate Pacific coast.

-Days 4-6: Continued above normal temperatures across the Southwest, Great Basin, and expanding into the Northern Rockies with anomalies of 4-8°F above normal.

-Days 7-10: Persistent above normal temperatures across the Southwest and Great Basin, with the warmest anomalies (6-10°F above normal) focused in Nevada, Utah, and western Colorado.

TROPICAL: 
EAST PACIFIC: There is a minor disturbance that has a near-zero chance of developing over the next few days. Further unfavorable conditions should continue to prevent any development.
