Mostly Dry
Mainly dry weather is expected today under the influence of high pressure to the east, although some showers are possible along the TX coast late.
General Overview: ACTIVE WEATHER PATTERN BRINGS RAIN AND THUNDERSTORMS TO THE GULF COAST AND SOUTHEAST, WHILE MIXED PRECIPITATION AND POSSIBLE FREEZING RAIN AFFECT THE PACIFIC NORTHWEST. COLD TEMPERATURES WILL DOMINATE THE CENTRAL US THROUGH THE PERIOD, WITH WARMING EXPECTED IN THE WEST DURING THE EXTENDED FORECAST.
EAST: A low pressure system will bring rain and thunderstorms to the Gulf Coast and Southeast through midweek. The heaviest precipitation is expected along the Gulf Coast from Louisiana to Florida, where thunderstorms may become strong at times. By Thursday, this system will shift eastward, bringing rain to much of the Southeast and Mid-Atlantic regions.
As we move into Friday, a new coastal low develops off the Carolina coast, bringing precipitation to the Mid-Atlantic and Northeast. This system may produce a wintry mix with possible freezing rain in portions of Virginia and the Delmarva Peninsula. High pressure will build in by 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 3-6 degrees below average. The coldest conditions will be in the Ohio Valley and interior Northeast.
-Days 4-6: Moderating temperatures with near normal conditions returning to the Southeast, while the Northeast remains slightly below normal.
-Days 7-10: Temperatures trending near to slightly below normal across most of the region, with the coldest anomalies gradually diminishing.
CENTRAL: High pressure will dominate the Central Plains initially, with cold air filtering southward. A frontal boundary extending from the Midwest to the Southern Plains will bring rain to portions of the region through midweek. As the system progresses, colder air will continue to filter into the region, with below normal temperatures becoming widespread.
By Thursday and Friday, high pressure will strengthen across the Central Plains, bringing dry conditions but maintaining the colder than normal temperatures. The Upper Midwest and Northern Plains will experience the most significant cold anomalies, with temperatures running 6-12 degrees below normal.
Temperature Anomalies:
-Days 1-3: Significantly below normal temperatures across the entire region, with the coldest anomalies (8-12 degrees below normal) centered on the Upper Midwest and Northern Plains.
-Days 4-6: Continued below normal temperatures, especially in the Northern Plains and Upper Midwest where anomalies remain 6-10 degrees below normal.
-Days 7-10: Gradual moderation of temperatures, though still generally below normal across the northern portions of the region. Near normal temperatures return to the Southern Plains.
WEST: A complex weather pattern will affect the Pacific Northwest and Northern Rockies, with mixed precipitation and possible freezing rain in Washington and Idaho. Several areas of low pressure will move through the region, bringing periods of precipitation to the Pacific Northwest and Northern Rockies through the week.
By Thursday, high pressure builds over the Southwest and Central Rockies, bringing dry conditions to those areas. The Pacific Northwest will continue to see precipitation, with snow in the higher elevations and a mix of rain and snow at lower elevations. Potential for freezing rain exists in portions of Washington and Idaho, which could create hazardous travel conditions.
Temperature Anomalies:
-Days 1-3: Near to slightly below normal temperatures for most of the region, with some cooler spots in the Northern Rockies.
-Days 4-6: Warming trend begins, with above normal temperatures developing across the Southwest and Great Basin. Anomalies of 3-6 degrees above normal will be common in these areas.
-Days 7-10: Continued warming with significant above normal temperatures (6-10 degrees above average) spreading across the entire Western region, particularly in the Great Basin, Southwest, and Pacific Northwest.
TROPICAL: No tropical cyclone activity is expected during the next 7 days in either the Atlantic or Eastern Pacific basins.
