Above Normal Temperatures Favor East and Great Lakes as Wetter Odds Stretch From California to the Plains

For November 18th to 22nd, warmer than normal temperatures are favored across most of the contiguous United States. The best chances, greater than 80 percent, sit over the Great Lakes region. Odds are lower across portions of the Southeast and Gulf Coast. Cooler than normal temperatures are favored over the West. Temperatures are expected to warm by the end of the period, especially across California and Oregon. In Alaska, above normal temperatures are likely over most of the state with the highest confidence over the eastern Mainland. Hawaii sees above normal temperatures favored over the eastern islands and near normal conditions for Oahu and Kauai. Forecast confidence is fairly high.

For November 18th to 22nd, wetter than normal conditions are favored from Oregon and California through much of the Rockies into the Plains and Mississippi Valley. There is some uncertainty about the exact track of any storm systems. Drier than normal weather is favored over the Northeast and portions of Washington state. In Alaska, below normal precipitation is favored for Southeast Alaska while above normal is generally favored over much of the Mainland. Hawaii is favored to see below normal precipitation across the island chain. Forecast confidence remains fairly high overall.

For November 20th to 26th, warmer than normal temperatures continue to be favored across most of the contiguous United States. The highest probabilities, exceeding 60 percent, cover the Great Lakes, Northeast, and Mid-Atlantic. Odds are reduced across portions of the Southeast and Gulf Coast. Near to below normal temperatures are favored over parts of the Great Basin and Four Corners region, while California and Oregon lean slightly toward above normal. Alaska again favors above normal temperatures over most of the state with highest confidence in the eastern Mainland. In Hawaii, above normal temperatures are favored for the Big Island while below normal temperatures are favored for Oahu and Kauai. Confidence stays fairly high.

For November 20th to 26th, wetter than normal conditions remain favored from Oregon and California through the Rockies into the Plains and Mississippi Valley, though chances are lower over the West than in the earlier period after a stretch of drier weather. A greater than 50 percent chance of above normal precipitation is forecast for the Central and Southern Plains. Near normal precipitation is favored for the Northeast. Below normal precipitation continues over portions of Washington state. Alaska favors below normal precipitation in the Southeast and near to above normal over much of the Mainland. Hawaii remains favored for below normal precipitation across the islands. Forecast confidence is fairly high.
