South: Widespread precipitation (more than 0.5 inch, locally more) was observed across the eastern two-thirds of Oklahoma, Arkansas, northern Louisiana, and eastern Texas. This precipitation maintained high soil moisture and streamflows throughout much of the southern Great Plains and lower Mississippi Valley. A slight reduction in the D0 and D1 areas was made to Cameron County in extreme southern Texas as more than 0.5 inch of rainfall occurred in the eastern part of that county. Persistent, dry weather along with periods of enhanced winds resulted in a slight expansion of abnormal dryness across the Texas Panhandle.
Looking Ahead: During the next 5 days (Jan. 17-21, 2019), a low pressure system is forecast to develop across the southern Great Plains and then track northeast to the Ohio Valley. This low pressure system is expected to become a strong coastal low near southern New England. A swath of moderate to heavy snow and freezing rain is likely to accompany the winter storm from the middle Mississippi Valley northeast to the northern mid-Atlantic and Northeast. Although mostly dry weather is forecast across ongoing drought areas of southern Texas, light rainfall is anticipated across southern Florida during the next five days.
Widespread rain and high-elevation snow are forecast throughout the western U.S. through early next week with heavy snow likely across the Cascades, Sierra Nevada, and Rockies. In the wake of the central and eastern U.S. winter storm this weekend, arctic high pressure is forecast to shift south from Canada and bring the coldest temperatures so far this winter to the northern Great Plains, Midwest, and Northeast. Periods of rainfall are expected across the western Hawaiian Islands during the next five days.
The CPC 6-10 day extended range outlook for Jan. 22-26, 2019, indicates enhanced odds for below normal temperatures across much of the eastern two-thirds of the continental U.S., along with the central Rockies, Great Basin, and Southwest. Above-normal precipitation is favored from the Mississippi Valley to the East Coast and also across the northern and central Great Plains. High odds for below-normal precipitation are forecast across the Pacific Northwest, Great Basin, and California. Above normal precipitation is favored throughout Alaska, while above normal temperatures are most likely across southern mainland Alaska and the Alaska Panhandle.
