Stormy East, Dry West

# General Overview: ACTIVE WEATHER PATTERN ACROSS THE NATION WITH HEAVY RAIN AND FLASH FLOODING THREATS ALONG THE EAST COAST THIS WEEKEND INTO MONDAY, MIXED PRECIPITATION IN THE NORTHERN ROCKIES AND PACIFIC NORTHWEST, AND POTENTIAL HEAVY SNOW IN PORTIONS OF THE NORTHERN ROCKIES. MULTIPLE LOW PRESSURE SYSTEMS WILL TRACK ACROSS THE COUNTRY BRINGING PRECIPITATION TO MANY REGIONS THROUGH THE WEEK.

## EAST:  
A significant low pressure system will impact the Eastern Seaboard through the weekend and early next week, bringing heavy rain and potential flash flooding to coastal areas from the Carolinas northward through the Mid-Atlantic and Northeast. The heaviest precipitation appears focused along the immediate coast where rainfall amounts could be substantial. Thunderstorms are also possible along parts of the coastal regions. By Sunday into Monday, this system begins to move offshore, but another low pressure system develops and continues to bring rain to portions of the Northeast and Mid-Atlantic.

As the week progresses, precipitation gradually diminishes across the East, with drier conditions returning by mid-week. The cold front associated with these systems will push through the region, bringing cooler air behind it.

Temperature Anomalies:

-Days 1-3: Near normal temperatures for most of the Eastern Seaboard, with slightly cooler conditions possible in areas experiencing persistent rainfall.

-Days 4-6: Temperatures trending near to slightly above normal for most areas as the system moves offshore and high pressure builds in.

-Days 7-10: Generally near normal temperatures prevailing across the region with some slightly above normal readings possible in the interior sections.

## CENTRAL:  
The Central U.S. will experience a variety of weather conditions as multiple systems move through the region. Initially, rain and thunderstorms will affect portions of the Northern Plains and Upper Midwest, with some rain extending into the North Central states. As the week progresses, a cold front will sweep through the region, bringing a line of precipitation with it.

The Central Plains will see varying precipitation chances throughout the forecast period as low pressure systems track through. By mid-week, a new system develops in the Central Plains, bringing additional precipitation chances to the region. The most significant temperature contrast will be across the Plains states where warmer air to the south meets cooler air to the north.

Temperature Anomalies:

-Days 1-3: Above normal temperatures across much of the Central Plains and portions of the Midwest, with anomalies of 3-6°F above normal, particularly in Kansas, Nebraska, and surrounding areas.

-Days 4-6: Continued above normal temperatures for the Central Plains, with the warmest anomalies (6-9°F above normal) focused on Oklahoma, Kansas, and parts of Missouri.

-Days 7-10: Persistent above normal temperatures across the Central Plains and Midwest, with the warmest anomalies (6-9°F above normal) centered on Kansas, Oklahoma, and surrounding states.

## WEST:  
Active weather will continue across the Western U.S. with multiple low pressure systems bringing precipitation to the region. The Pacific Northwest and Northern Rockies will experience mixed precipitation, with rain at lower elevations and snow at higher elevations. A particularly noteworthy system will affect Arizona, where heavy snow is possible in the higher terrain.

The Southwest will see periods of rain and thunderstorms, particularly across Arizona and New Mexico. California will experience periods of rain along the coast and in the northern portions of the state. By mid-week, additional low pressure systems move into the West Coast, bringing more precipitation chances to the region.

Temperature Anomalies:

-Days 1-3: Above normal temperatures across much of the Southwest and Rockies, with the warmest anomalies in Idaho, Wyoming, and Montana. Below normal temperatures along portions of the West Coast, particularly in California.

-Days 4-6: Below normal temperatures expanding across the Pacific Northwest and Northern Rockies, with anomalies of 3-6°F below normal. Continued above normal temperatures in the Southwest.

-Days 7-10: Below normal temperatures persisting along the West Coast, particularly California and Nevada (3-6°F below normal). Above normal temperatures continuing across portions of the Southwest and Southern Rockies.

## TROPICAL:
Tropical Storm Raymond is noted in the Eastern Pacific off the coast of Mexico. The system appears to be moving away from land and is not expected to have significant direct impacts on the continental United States.

In the Atlantic; Tropical Storm Jerry is expected to continue north before turning east remaining a tropical storm and not producing any impacts to mainland US. Additionally, a tropical wave well to the south of the Cabo Verde Islands will continue moving west-northwest with a 20% chance of formation through the next 7 days.
