The US is drying out a bit after weeks of above-normal precip in many regions. That said, much of the western and southern US lean wet. The North Central to the Northeast, and down the Miss River, lean dry. Temps: Warmer than normal likely for almost all of the US. @NOAA @NWS

2026-2027 winter outlook! ☃ El Niño is underway and is strengthening. This certainly plays a role in the outlook, but its not the only player. Besides, no 2 years are alike. Above-normal temps are favored. Equal chances for precipitation.... 🧵
