Drying Out
Lingering snow showers are possible early this morning across IL and IN, with dry conditions setting in elsewhere.
General Overview: ACTIVE WEATHER PATTERN ACROSS THE EASTERN THIRD OF THE NATION WITH RAIN AND THUNDERSTORMS ALONG THE SOUTHEAST COAST AND POTENTIAL FREEZING RAIN IN THE MID-ATLANTIC REGION. MIXED PRECIPITATION EXPECTED ACROSS THE NORTHERN PLAINS AND PACIFIC NORTHWEST. BELOW NORMAL TEMPERATURES WILL DOMINATE THE CENTRAL STATES WHILE WARMER CONDITIONS DEVELOP ACROSS THE WEST.
EAST: A complex weather system will bring significant precipitation to the Eastern Seaboard over the next few days. Rain and thunderstorms are expected along the Southeast coast and Gulf Coast of Florida on Tuesday, with the potential for heavy rainfall in some locations. Of particular concern is the risk of freezing rain across portions of the Mid-Atlantic, especially in Virginia, Maryland, and parts of Pennsylvania. This freezing rain threat could create hazardous travel conditions and potential power outages.
By Wednesday, high pressure builds into the Northeast, pushing the precipitation southward. The coastal low pressure system will shift eastward, bringing improving conditions to much of the region by Thursday. Another system may approach the Southeast coast by Friday, bringing additional rain to coastal areas.
Temperature Anomalies:
-Days 1-3: Generally near to slightly below normal temperatures across most of the region, with the coldest anomalies (3-6°F below normal) in the Mid-Atlantic states.
-Days 4-6: Temperatures moderate to near normal for most areas, with slightly below normal readings continuing in the interior Northeast.
-Days 7-10: Temperatures trend toward normal or slightly below normal for most of the region, with the coldest anomalies gradually shifting northward.
CENTRAL: The Central United States will experience a significant temperature contrast over the next several days. A cold front will push through the region Tuesday into Wednesday, bringing much colder air to the Plains and Midwest. Areas of mixed precipitation are likely across the Northern Plains, particularly in the Dakotas and Nebraska, where some snow accumulation is possible.
By midweek, high pressure will dominate the region, bringing dry but cold conditions to most areas. The Gulf Coast states will see rain and possibly thunderstorms on Wednesday as the frontal boundary stalls along the coast. Another system may bring precipitation chances to the Southern Plains by late week.
Temperature Anomalies:
-Days 1-3: Significantly below normal temperatures across the Central Plains and Midwest, with anomalies of 6-12°F below normal in parts of the Dakotas, Nebraska, and Iowa.
-Days 4-6: Continued below normal temperatures across most of the region, with the coldest anomalies shifting slightly eastward into the Upper Midwest and Great Lakes.
-Days 7-10: Gradual moderation of temperatures, though still remaining below normal across the northern portions of the region. Near normal temperatures return to the Southern Plains.
WEST: Multiple low pressure systems will affect the Western states over the next several days. Mixed precipitation is expected across the Pacific Northwest and portions of the Northern Rockies on Tuesday and Wednesday. Snow will be possible in higher elevations of Washington, Oregon, Idaho, and western Montana.
By midweek, precipitation chances shift southward into the Four Corners region, with mixed precipitation possible in higher elevations. The Southwest will remain mostly dry. Another system approaches the Pacific Northwest by Friday, bringing additional precipitation chances to the region.
Temperature Anomalies:
-Days 1-3: Near to slightly below normal temperatures across much of the region, with the coldest readings in the Northern Rockies.
-Days 4-6: Warming trend begins, with above normal temperatures developing across the Southwest and Great Basin. Temperatures remain near normal in the Pacific Northwest.
-Days 7-10: Significantly above normal temperatures develop across much of the West, particularly in the Interior Northwest and Northern Rockies, where anomalies could reach 6-10°F above normal.
TROPICAL: No tropical cyclone activity is expected during the next 7 days in either the Atlantic or Eastern Pacific basins.
