Weekend forecast: Warm and muggy with scattered afternoon storms

/ August 18, 2023 at 9:42 PM

The weather this weekend looks fairly August-like — lows in the mid-70s, highs in the low 90s, with a chance for thunderstorms each afternoon, but no rainouts, either.

Moisture begins to return to the area Saturday as a front approaches and stalls out nearby. The front won’t be a huge contributor to storm chances, it looks like, with the seabreeze doing a bulk of the dirty work in the afternoon and evening hours. The moisture isn’t very deep, though, and that should limit storms to generally isolated to scattered coverage. Highs top out in the low-to-mid-90s; combine this with dewpoints heading into the low 70s, we should see heat indices around 100° for a time.

Trajectories turn more onshore for Sunday, which will act to keep a chance for scattered showers and storms in the forecast for much of the day, progressing inland with time. Widespread coverage isn’t expected, though, and it won’t rain all day at any one location. Highs top out in the low 90s with heat indices around 100-101°.

This might be the last real rain we see for a few days as an expansive ridge builds in across the area for the upcoming work week (and first week of school), which may send heat indices back over 105° across the area for a good chunk of each afternoon. It remains to be seen if heat advisory-level conditions return — stay tuned.
