Summary

A significant weather system impacted the lower Mississippi Valley and pushed northeast into the Ohio River Valley and the Northeast. The active pattern over the Pacific Northwest and northern Rocky Mountains continued, bringing much-needed rain and snow to these regions. Cooler than normal temperatures dominated the Plains region and the South, with areas of the northern Plains 15-20 degrees below normal. Warmer than normal conditions dominated the West, with areas of the Great Basin 10-15 degrees warmer than normal…

High Plains

Much of the region did record precipitation in the form of both snow and rain during the last week, but amounts were generally less than half an inch. Some areas of east central Kansas did record close to an inch of precipitation. The most significant changes this week were due to a reanalysis of the data over the short term. From this analysis, the extreme drought over western South Dakota was improved to severe drought status. The impact designation also was changed from a combination of short- and long-term impacts to only long-term impacts. Dryness in southern Kansas and eastern Colorado continued with an expansion of the severe drought conditions to the west, incorporating all of southwestern Kansas and extreme southeastern Colorado. Extreme drought conditions were also pushed more to the west in southern Kansas…

West

The coastal regions of the Pacific Northwest as well as the northern Rocky Mountains again had the most precipitation. Areas of southern Nevada and the desert regions of southern California and western Arizona finally recorded some precipitation. Areas of southern California that had experienced fires late last year were impacted by mudslides from the heavy rains that inundated the region. Even with the precipitation in Oregon, the water year continues to be well below normal for precipitation, which allowed for the expansion of abnormally dry conditions in Oregon, western Idaho, and southern Washington. A new area of moderate drought was introduced from central Oregon to western Idaho. In Utah, the low snow and snow water equivalency values caused an expansion of severe drought in central Utah and moderate drought in northeastern Utah. Abnormally dry conditions were pushed to include all of northern Utah and extreme southwestern Wyoming. In eastern New Mexico, severe drought conditions were expanded over the region…

Looking Ahead

Over the next 5-7 days, the active pattern over the Pacific Northwest is anticipated to continue, with heavy rains along the coastal areas from northern California up to Seattle. Farther inland, precipitation should be widespread from Washington and Oregon into Idaho and western Montana, with the greatest amounts over the panhandle of Idaho. Precipitation from the central Rocky Mountains will pass through the central Plains and into the upper Midwest and Great Lakes. Much of the eastern half of the United States is projected to receive precipitation. During this period, temperatures are anticipated to be 3 to 6 degrees below normal west of the Continental Divide and 6 to 9 degrees above normal to the east. This should help bring the snow levels down over the western United States, allowing for snow accumulation to take place.

The 6-10 day outlooks show that temperatures are anticipated to remain cooler than normal over the western and north central United States, with the greatest probability of below-normal temperatures over Montana and Wyoming. Warmer than normal temperatures are projected over much of the eastern third of the country, with the greatest chances of above-normal temperatures along the eastern seaboard from Florida north into New England. The probability of above-normal precipitation is great over much of the United States outside of the desert Southwest. The highest chances of above-normal precipitation are over the Great Basin and lower Mississippi Valley.
