Overview
- Light rain develops this afternoon from the Mid-Atlantic into southern New England, changing to a brief rain–snow mix overnight with mainly minor impacts and a coating to around 1 inch in higher terrain.
- Pittsburgh and surrounding areas stay mild today with 40s to near 50 before any evening mix in the ridges, and Presidents Day trends dry with temperatures near or above average.
- California faces a high-impact system Monday–Tuesday with flood watches, wind advisories and high surf; coastal plains could see 1–3 inches of rain with higher totals along foothills and mountains.
- Northern California forecasts call for 1–2 inches of valley rain and 2–5 feet of Sierra snow, with a rainier Sunday–Monday wave followed by a colder, windier Tuesday wave that drops snow levels to roughly 2,500–3,000 feet by midweek.
- The same developing low is expected to drive severe storms over parts of the Gulf Coast and Southeast in the next two days, including risks for damaging winds and tornadoes.
