Snow Showers Linger
Periods of lake-effect snow will persist off of Lakes Erie and Ontario today, with scattered light snow expected across much of the remainder of the region.
General Overview: MIXED PRECIPITATION ACROSS THE GREAT LAKES AND PACIFIC NORTHWEST WITH POTENTIAL FOR HEAVY SNOW FOR PARTS OF THE GREAT LAKES REGION. BELOW NORMAL TEMPERATURES ACROSS THE EASTERN HALF OF THE COUNTRY CONTRASTING WITH ABOVE NORMAL TEMPERATURES IN THE WEST. MULTIPLE HIGH PRESSURE SYSTEMS WILL DOMINATE THE CENTRAL AND SOUTHEASTERN REGIONS THROUGH MIDWEEK.
EAST: A cold front will push through the Northeast and Mid-Atlantic regions early in the period, bringing mixed precipitation to the Great Lakes and parts of New England. Areas around the Great Lakes can expect periods of snow and mixed precipitation through the remainder of the work week, with areas downwind of Lake Ontario and Lake Erie potentially seeing heavy snow accumulations. By midweek, high pressure will build across the Southeast, bringing drier conditions to much of the eastern seaboard. The cold front will move offshore by Wednesday, allowing for clearing conditions across the Northeast. By the weekend, conditions should remain generally dry across most of the East as high pressure dominates.
Temperature Anomalies:
-Days 1-3: Significantly below normal temperatures across the entire eastern region, with anomalies of 6-12 degrees below normal, particularly across the Southeast and Mid-Atlantic. The coldest anomalies will be centered over the Carolinas and Georgia.
-Days 4-6: Gradual moderation of temperatures, though still remaining below normal for most areas. Florida and the coastal Southeast will see temperatures returning closer to normal by day 6.
-Days 7-10: Near normal temperatures return to most of the East, with only slight below normal readings lingering in parts of the Northeast. By day 10, temperature anomalies become minimal across the region.
CENTRAL: Generally dry conditions continue today as high-pressure affects the region. The Upper Midwest may experience mixed precipitation at times. As the week progresses, high pressure will dominate across much of the Central region, bringing generally dry conditions to the Plains states. By late week, a warming trend will develop across the Central Plains and Upper Midwest as the temperature pattern begins to reverse. A new frontal system may approach from the west by the weekend, bringing precipitation chances to parts of the Northern Plains.
Temperature Anomalies:
-Days 1-3: Below normal temperatures across the eastern portions of the Central region, particularly in the Ohio Valley and Lower Mississippi Valley. Near normal to slightly above normal temperatures in the western portions of the region.
-Days 4-6: Significant warming trend develops with above normal temperatures spreading across the Central Plains and Upper Midwest. By day 6, temperature anomalies of 6-12 degrees above normal will be common across Oklahoma, Kansas, Nebraska, and parts of Iowa.
-Days 7-10: Continued above normal temperatures across much of the Central region, though anomalies moderate somewhat. By day 10, temperatures return closer to seasonal norms across most areas.
WEST: Active weather pattern across the Pacific Northwest and Northern Rockies with periods of rain and mountain snow. A series of low pressure systems will affect the West Coast, bringing precipitation to Washington, Oregon, and Northern California. The Southwest will remain generally dry under high pressure influence. By midweek, a new frontal system will approach the Pacific Northwest, bringing another round of precipitation. The Intermountain West will see variable conditions with periods of mountain snow. Southern California and the Desert Southwest will remain mostly dry throughout the period.
Temperature Anomalies:
-Days 1-3: Above normal temperatures across most of the West, with the warmest anomalies (6-12 degrees above normal) centered over the Northern Rockies, particularly in Idaho and western Montana.
-Days 4-6: Continued above normal temperatures, with the warmest anomalies shifting slightly eastward into Wyoming and Colorado. The Pacific Northwest will see temperatures closer to normal as frontal systems move through.
-Days 7-10: Gradual cooling trend with temperatures returning closer to seasonal norms across most of the West. By day 10, only slight temperature anomalies remain across the region.
TROPICAL: No tropical cyclone activity is expected during the next 7 days in either the Atlantic or Eastern Pacific basins.
