Scattered Rain Developing for Some

General Overview: ACTIVE WEATHER PATTERN CONTINUES ACROSS THE NATION WITH MIXED PRECIPITATION IN THE WEST, POTENTIAL HEAVY RAIN AND THUNDERSTORMS IN THE SOUTHWEST, AND SNOW ACROSS PORTIONS OF THE NORTHERN ROCKIES. TEMPERATURES WILL REMAIN BELOW NORMAL ACROSS THE EASTERN THIRD OF THE COUNTRY WHILE ABOVE NORMAL TEMPERATURES DOMINATE THE WESTERN AND CENTRAL REGIONS.

EAST:  A low pressure system will track through the Northeast on Wednesday, bringing a mix of precipitation to the region. Cold air in place will support snow across interior sections of New England, with rain along the immediate coast. By Thursday, high pressure builds in across the Mid-Atlantic and Southeast, bringing drier conditions. However, by the weekend, a new frontal system approaches from the Gulf Coast, bringing rain to portions of the Southeast and potentially some thunderstorm activity. The Northeast will remain generally dry through the weekend under high pressure influence.

Temperature Anomalies:

-Days 1-3: Below normal temperatures will dominate the region, with departures of 3-8 degrees below average, particularly across the Northeast and Mid-Atlantic. The coldest anomalies will be focused in New England.

-Days 4-6: Temperatures begin to moderate slightly but remain below normal across much of the region. Florida will see near normal temperatures while the rest of the Southeast gradually warms.

-Days 7-10: Temperatures trend closer to normal by the end of the period, with only slight below-normal readings persisting in parts of the Northeast. The Southeast returns to near or slightly above normal.

CENTRAL:  A frontal boundary will move through the Central Plains on Wednesday, with low pressure developing along the front. This will bring a chance of snow to portions of Nebraska and Kansas. As the system moves eastward, high pressure builds in behind it, bringing generally dry conditions to much of the Central region for Thursday and Friday. By the weekend, a new low pressure system develops over eastern Texas, bringing rain to the Gulf Coast states and potentially pushing northward into the lower Mississippi Valley. The upper Midwest and Northern Plains will remain mostly dry under high pressure influence.

Temperature Anomalies:

-Days 1-3: A sharp temperature contrast will be evident with below normal temperatures east of the Mississippi River and above normal temperatures west of the Mississippi. The Northern Plains will see temperatures 6-10 degrees above normal.

-Days 4-6: Warmer than normal conditions expand across most of the Central region, with the warmest anomalies (6-12 degrees above normal) focused on the Southern Plains and extending northward into the Dakotas.

-Days 7-10: Above normal temperatures continue across most of the region, though anomalies moderate somewhat. The Southern Plains will maintain temperatures 4-8 degrees above normal, while the Upper Midwest returns closer to seasonal averages.

WEST:  An active pattern continues across the Western states with multiple systems bringing precipitation. Mixed precipitation will affect the Pacific Northwest and Northern Rockies on Wednesday and Thursday, with rain at lower elevations and snow at higher elevations. The Southwest will see rain and thunderstorms, with potential for heavy rainfall and flash flooding in parts of Arizona and southern California. By the weekend, another system moves into the Pacific Northwest, bringing additional precipitation to the region. High pressure over the Great Basin will provide drier conditions for the interior West during the latter part of the period.

Temperature Anomalies:

-Days 1-3: Above normal temperatures will dominate most of the West, with the warmest anomalies (6-10 degrees above normal) focused on the Rocky Mountain states. The Pacific Northwest will see more moderate warm anomalies of 2-6 degrees above normal.

-Days 4-6: Continued above normal temperatures across the entire region, with the warmest anomalies shifting slightly eastward into the Central and Southern Rockies. Temperature departures of 6-12 degrees above normal will be common across the interior West.

-Days 7-10: Warm anomalies persist but gradually moderate through the period. Most areas will remain 3-6 degrees above normal, with the strongest warm anomalies continuing across the Rocky Mountain states.
