Light Snow Showers Possible Today

General Overview: ACTIVE WEATHER PATTERN ACROSS THE EASTERN HALF OF THE COUNTRY WITH RAIN AND SNOW THREATS THROUGH THE WORK WEEK AND WEEKEND. A COLD FRONT WILL PUSH THROUGH THE GREAT LAKES AND OHIO VALLEY FRIDAY INTO SATURDAY, BRINGING RAIN AND MIXED PRECIPITATION. BY SUNDAY, THE SYSTEM SHIFTS OFFSHORE WITH ANOTHER LOW DEVELOPING IN THE SOUTHWEST. TEMPERATURES WILL FLUCTUATE WITH ABOVE NORMAL READINGS IN THE WEST AND BELOW NORMAL CONDITIONS SPREADING ACROSS THE EASTERN HALF OF THE COUNTRY BY EARLY NEXT WEEK.

EAST:  A frontal system will move through the Great Lakes and Northeast today, bringing a mix of rain and snow to the region. Areas of mixed precipitation will affect parts of the Ohio Valley and Mid-Atlantic, with rain extending along the front into the Southeast. A new system will bring additional chances for snow across the Great Lakes, Northeast, and Mid-Atlantic Friday and into Saturday, with rain extending into the Southeast again. By Sunday, the coastal low will strengthen and move northeastward, with precipitation continuing along the Eastern Seaboard. Cold air will filter in behind the system, changing any remaining precipitation to snow across parts of the Northeast and Great Lakes region. Monday will see improving conditions as high pressure builds in from the west.

Temperature Anomalies:

-Days 1-3: Above normal temperatures across the Northeast and Mid-Atlantic on day 1 (6-12°F above normal), transitioning to below normal by day 3 as cold air filters in. The Southeast will experience a cooling trend with temperatures falling to 3-6°F below normal by day 3.

-Days 4-6: Below normal temperatures will dominate the eastern third of the country, with anomalies of 3-8°F below normal. The coldest readings relative to normal will be across the Southeast and Mid-Atlantic regions.

-Days 7-10: Continued below normal temperatures across most of the East, gradually moderating by day 10. Some areas in the Northeast may return to near normal by the end of the period.

CENTRAL: Snow showers will push into the North/Central Plains and Midwest today, bringing snow showers across the region, with snow lingering across the Upper Midwest on Saturday. High pressure will dominate the Central Plains, keeping conditions dry into the weekend. Sunday and into Monday, high-pressure will prolong dry conditions across much of the Central US, although the upper Midwest will likely see continuing periods of snow.

Temperature Anomalies:

-Days 1-3: Near to slightly above normal temperatures across most of the Central region, with the warmest anomalies (3-6°F above normal) in the Central Plains. The Upper Midwest will see temperatures transition from near normal to slightly below normal by day 3.

-Days 4-6: A cooling trend will spread across the region with below normal temperatures (3-8°F below normal) becoming established across the eastern half of the Central states. The Northern Plains will experience the coldest anomalies.

-Days 7-10: Below normal temperatures will continue across much of the Central region, particularly in the Northern Plains and Upper Midwest where anomalies could reach 6-10°F below normal. Some moderation is expected by day 10 with near normal temperatures returning to the Southern Plains.

WEST:  High pressure will dominate much of the Western states through the remainder of the work week and through the weekend, bringing generally dry conditions. Rain and high-elevation snow may be seen across the North/Central Rockies and Intermountain West, however. Sunday and into early next week, strong high-pressure may mitigate precipitation chances across the region.

Temperature Anomalies:

-Days 1-3: Above normal temperatures across much of the West, with the warmest anomalies (6-12°F above normal) in the Northern Rockies and Pacific Northwest. The Southwest will see temperatures 3-6°F above normal.

-Days 4-6: Continued above normal temperatures for most of the West, though slightly moderating from the peak warmth of days 1-3. The Northern Rockies and parts of the Pacific Northwest will still see temperatures 3-8°F above normal.

-Days 7-10: A gradual cooling trend will develop, with temperatures returning closer to normal across much of the region. Some areas in the Northern Rockies may see below normal temperatures by day 10, while the Southwest remains slightly above normal.

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