Overview
- A strong dome of high pressure is producing dry, mostly sunny conditions this workweek and will warm many inland areas into the 80s with upper‑80s and isolated 90s expected by Friday.
- Humidity will stay low through midweek but turn noticeably stickier late in the week, with dew points peaking on Saturday and making the warm air feel more oppressive for outdoor activity.
- A frontal boundary approaching late Thursday night into the weekend will return scattered showers and thunderstorms Saturday into Sunday, and local model timing remains uncertain for exact storm placement and timing.
- The Storm Prediction Center has placed portions of the Great Lakes and upper Plains under a marginal risk for isolated severe storms, where hail and damaging gusts are the primary threats.
- Separately, southern Nevada faces an extreme heat burst with forecast highs near 104–106°F on Thursday and Friday that create a major heat‑health risk, and the India Meteorological Department says the southwest monsoon is likely to reach Kerala within two to three days while projecting below‑normal seasonal rainfall at about 90 percent of the long‑period average due in part to developing El Niño conditions.
