Overview
- A widespread warm, dry stretch that held through midweek is being interrupted by eastwardmoving fronts that will cool many interior and northern areas and bring rounds of rain starting late this week.
- The National Weather Service has issued a Coastal Flood Advisory for parts of the San Francisco Bay Area and warned of hazardous surf, sneaker waves, and strong rip currents along affected beaches.
- Boston and much of New England face steadier rain and the risk of downpours that could slow Friday commutes with the heaviest, localized rainfall focused in southeastern Massachusetts.
- South‑central Montana’s Billings foothills will see elevated winds Thursday into the weekend with the windiest conditions Friday and Saturday and a current estimate that gusts over 50 mph remain below a 50 percent probability.
- Most regions are forecast only modest rain totals of roughly 0.25 to 1 inch but forecasters warn that slow or training bands could produce localized flooding and that post‑frontal cooling will raise frost and first‑freeze risks in sheltered inland spots.
