Warm Today

General Overview: ACTIVE WEATHER PATTERN ACROSS THE EASTERN HALF OF THE COUNTRY WITH MIXED PRECIPITATION ACROSS THE GREAT LAKES AND NORTHEAST, WHILE RAIN AND THUNDERSTORMS AFFECT THE SOUTHEAST AND GULF COAST. PACIFIC NORTHWEST WILL SEE PERIODS OF RAIN AND MOUNTAIN SNOW. TEMPERATURES WILL START ABOVE NORMAL FOR MUCH OF THE CENTRAL US BEFORE COOLING TREND DEVELOPS LATER IN THE WEEK.

EAST:  An area of low-pressure will bring widespread precipitation to the Eastern US through the middle of the week. The Northeast and Great Lakes will experience mixed precipitation, with rain largely turning to snow throughout Wednesday and into Thursday. Scattered rain and a few thunderstorms will become possible for the Southeast and Mid Atlantic. As the system evolves, gusty northwesterly flow will bring periods of lake-effect snow off of the Great Lakes throughout Thursday and Friday. By the weekend, high-pressure may bring drier conditions to most areas.

Temperature Anomalies:

-Days 1-3: Above normal temperatures for most of the region, particularly across the Southeast where temperatures will run 4-8°F above normal. The Northeast will see more moderate warmth of 2-4°F above normal.

-Days 4-6: A cooling trend develops with temperatures falling to near or slightly below normal for most areas. The cooling will be most pronounced across the Mid-Atlantic and Southeast, where temperatures will drop to 2-4°F below normal.

-Days 7-10: Temperatures remain slightly below normal for most areas, though the Southeast will begin to moderate back toward normal by day 10. The Northeast will continue with slightly below normal temperatures.

CENTRAL: Initially, a low pressure system will bring rain to portions of Southern Mississippi Valley, while areas of mixed precipitation affect the Northern Plains and Upper Midwest through the middle of the week. As the system moves eastward, high pressure will build into the region, bringing drier conditions by late week. However, another system may begin to affect portions of the Plains by the weekend with rain and possibly some mixed precipitation possible for northern areas.

Temperature Anomalies:

-Days 1-3: Significantly above normal temperatures across much of the region, with the warmest anomalies (6-10°F above normal) centered on the Northern Plains and Upper Midwest.

-Days 4-6: A dramatic shift occurs as cooler air filters in from the north. Temperatures will fall to below normal across most of the region, with the Northern Plains seeing temperatures 4-8°F below normal.

-Days 7-10: Below normal temperatures become entrenched across the region, particularly across the Northern Plains and Upper Midwest where temperatures will run 6-10°F below normal. The southern portions will see less dramatic cooling.

WEST:  The Pacific Northwest and Northern Rockies will likely see an active pattern throughout much of this week, with periods of rain along the coast and snow in the higher elevations. Several high pressure systems will influence the weather pattern, bringing generally dry conditions to the Southwest and California. By late week, a new system will approach the Pacific Northwest, bringing another round of precipitation to the region. The Southwest will remain largely dry throughout the period, though some moisture may work into portions of Arizona and New Mexico by the weekend.

Temperature Anomalies:

-Days 1-3: Near to slightly above normal temperatures for most areas, with the warmest conditions (2-4°F above normal) across the Southwest and Great Basin.

-Days 4-6: Temperatures trend cooler across the Northern Rockies and Pacific Northwest, falling to 2-6°F below normal. The Southwest remains slightly above normal.

-Days 7-10: Below normal temperatures become more widespread across the northern tier of the region, with near normal temperatures returning to the Southwest and California.

TROPICAL:
No tropical cyclone activity is expected during the next 7 days in either the Atlantic or Eastern Pacific basins.
