Overview
- Southerly flow is replacing early-week cold, pushing highs back into the 50s and 60s in many areas with frequent gusts around 25 to 35 mph.
- NOAA’s Space Weather Prediction Center reports a continuing geomagnetic storm through Wednesday night, with aurora visible unusually far south after multiple CME arrivals.
- Forecasters expect a potent storm to reach California late Thursday into Friday, delivering widespread rain, mountain snow near or above 6,000 feet, and strong onshore winds.
- NWS guidance calls for roughly 1–2 inches of rain in coastal and valley areas and 2–4 inches in mountains and foothills, with possible flood watches and debris-flow concerns near recent burn scars.
- Across the Midwest and Northeast, forecasts increasingly favor a Saturday night to Sunday rain window, while northern New England holds onto scattered snow showers and a potential wintry start Sunday before a change to rain.
