Data valid as of Jan. 8, 2019
South: Widespread moderate to heavy precipitation (0.5 to 2.5 inches, liquid equivalent) fell across the lower Mississippi Valley and parts of the southern Great Plains for the second consecutive week. The recent precipitation during an ideal time of year for soil moisture recharge resulted in the removal of any lingering abnormal dryness (D0) across northeast Oklahoma. However, the long-term drought area in the Texas Panhandle remained mostly west of the heavier precipitation and south Texas remained dry during the past week. Short-term abnormal dryness (D0) and moderate drought (D1) were expanded in southern Texas where 90-day deficits ranged from 1 to 4 inches.
Looking Ahead: Temperatures are forecast to average near to slightly below normal across the southern tier of the continental U.S. and along the East Coast. Short-term dryness is likely to increase across south Florida and the lower Rio Grande Valley through mid-January. Mostly dry weather is also forecast for the northern half of the Rockies extending east to the northern Great Plains and upper Mississippi Valley. Much above-normal temperatures are likely to accompany the dry weather across these areas. Elsewhere, additional rain and high-elevation snow is anticipated for California as onshore flow persists.
The CPC 6-10 day extended range outlook (Jan. 15-19, 2019) favors near to above normal precipitation across the western two-thirds of the continental U.S. with the highest odds forecast across California and Nevada. The most likely areas to experience below normal precipitation are parts of the Northeast and Florida Peninsula. The highest probabilities for above normal temperatures are forecast along the West Coast and central to southern high Plains, while near to below normal temperatures are favored across the eastern U.S. during this 5-day period.
