Overview
- Much of the country has turned cooler with clouds and scattered showers to start the week and below‑average highs in the 40s–60s for many areas.
- Forecasters say Tuesday will bring the highest rain impacts across parts of the Mid‑Atlantic and New England with steady rain and onshore winds expected.
- Model guidance shows an offshore low forming late in the week that many runs deepen and steer northward, which would produce multi‑day nor’easter conditions along the Mid‑Atlantic and New England coasts.
- Out West a short-lived ridge is forecast to build midweek, likely pushing interior California temperatures into the 80s and 90s and prompting meteorologists to watch for possible heat advisories for inland areas.
- A strong monsoon surge is expected across parts of the Southwest Tuesday–Thursday with widespread heavy downpours and elevated flash‑flood risk on recent burn scars.
