US Braces for Record Warm November Amid El Niño
7 Nov
Summary
- November is projected to be one of the warmest on record across the US.
- El Niño is the primary driver of the unusually warm November temperatures.
- Above-average temperatures are expected nearly nationwide, except for the Southwest.
The United States is set to experience one of its warmest Novembers on record, a stark contrast to typical seasonal expectations. The dominant factor influencing this unusual warmth is the ongoing El Niño, which is significantly impacting weather patterns nationwide. Forecasters indicate that nearly the entire country can expect above-average temperatures throughout November.
The only exception to this widespread warmth is the Southwest, where conditions are forecast to have an equal chance of being warmer or cooler than normal. No regions are predicted to experience below-average temperatures. This pattern of warmth is attributed to an energized Pacific jet stream, fueled by both El Niño and marine heatwaves.
Beyond temperature, precipitation forecasts show the Southwest and the central and northern Plains are likely to see the most significant rainfall. Conversely, Michigan and Montana are the only states anticipated to have a drier-than-average November. Concerns for coastal flooding persist, particularly in Southern California, with the highest water levels expected around November 25th.
Looking ahead, the warm trend is projected to continue into December and beyond, as El Niño typically leads to warmer winters, especially in the northern half of the U.S. This is due to altered jet stream patterns that make prolonged cold air intrusions less probable.
