Dry and Cold

General Overview: ACTIVE WEATHER PATTERN ACROSS THE EASTERN HALF OF THE COUNTRY WITH RAIN, SNOW, AND MIXED PRECIPITATION EXPECTED THROUGH MIDWEEK. A LOW PRESSURE SYSTEM WILL TRACK FROM THE GULF COAST NORTHEASTWARD ALONG THE EASTERN SEABOARD, BRINGING PRECIPITATION TO MUCH OF THE SOUTHEAST AND MID-ATLANTIC REGIONS. MEANWHILE, HIGH PRESSURE DOMINATES THE WESTERN STATES WITH ABOVE NORMAL TEMPERATURES EXPECTED ACROSS THE ROCKIES AND NORTHERN PLAINS.

EAST:
A developing low pressure system will move from the Gulf Coast northeastward along the Eastern Seaboard through midweek. On Tuesday, rain will spread across the Southeast and Tennessee Valley, with some mixed precipitation possible along the northern edge of the precipitation shield. By Wednesday, the low will intensify off the Carolina coast, bringing rain to much of the Mid-Atlantic and coastal Northeast. Some snow is possible in the higher elevations of the Appalachians. As the system moves offshore Thursday into Friday, precipitation will gradually end from southwest to northeast. High pressure builds in for the weekend, bringing drier conditions to most of the region.

Temperature Anomalies:
-Days 1-3: Below normal temperatures across most of the region, with anomalies of 6-12 degrees below normal, particularly in the Mid-Atlantic and Southeast.
-Days 4-6: Continued below normal temperatures for most areas, gradually moderating by day 6 with near normal temperatures returning to the Southeast.
-Days 7-10: Below normal temperatures persist across the Northeast and Mid-Atlantic, with near normal temperatures returning to the Southeast and Gulf Coast.

CENTRAL:
A frontal boundary will move through the Central Plains and Midwest early in the period, bringing a chance of snow to portions of the Northern Plains and Upper Midwest. Mixed precipitation is possible across parts of the Central Plains and Mid-Mississippi Valley. By midweek, high pressure will build into the region, bringing drier conditions. Another system may approach from the west by late in the period, bringing a chance of snow to the Northern Plains and Upper Midwest.

Temperature Anomalies:
-Days 1-3: Near normal temperatures across much of the region, with slightly below normal temperatures in the eastern portions and above normal temperatures building in the western portions.
-Days 4-6: Above normal temperatures expand across the Plains and Upper Midwest, with anomalies of 6-12 degrees above normal in the Northern Plains.
-Days 7-10: Above normal temperatures continue across the Plains, gradually moderating by the end of the period.

WEST:
High pressure will dominate the Western states through much of the period, bringing generally dry conditions to most areas. Some light snow is possible across the Northern Rockies and Pacific Northwest early in the period. By midweek, a ridge of high pressure strengthens over the region, bringing warmer than normal temperatures to much of the West. Some precipitation may return to the Pacific Northwest by the weekend as a weak system approaches the coast.

Temperature Anomalies:
-Days 1-3: Above normal temperatures across most of the region, with anomalies of 6-12 degrees above normal in the Rockies and Interior Northwest.
-Days 4-6: Continued above normal temperatures, with the warmest anomalies (8-12 degrees above normal) focused on the Northern Rockies and Northern Plains.
-Days 7-10: Above normal temperatures persist across most of the West, gradually moderating by the end of the period.

TROPICAL:
No tropical cyclone activity is expected during the next 7 days.
