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.
Drier air moves into the area for Friday, yielding mostly sunny skies and a rain-free day. We start the day in the mid-70s before highs head to the mid-90s in the afternoon. Drier air mixing down from aloft will temper dewpoints somewhat, and this will help to keep heat indices from getting too far out of hand. Still, feels-like temperatures will top out in the mid-to-upper 90s. So, while it’s not going to be cool outside, it’s also not going to feel like it’s 110°. (Take the wins where you can get them.)
Scattered storms head back into the forecast starting Saturday afternoon as a front stalls out nearby and waves of low pressure move along it. Surface dewpoints will head back into the mid-70s, and this will yield heat indices over 100° Saturday afternoon before storms fire. Still, coverage should be scattered at most with ridging aloft creating a bit of capping.
Sunday will run a tad cooler (air temperature-wise, anyway) as surface winds turn more onshore. Expect highs in the upper 80s to around 90° in the afternoon, but heat indices will run around 100°. Scattered showers and some thunderstorms will be embedded within this onshore flow, and will be coming ashore from time to time, but by no means is it a washout as coverage should once again generally be in the scattered category. So, while it’s not the perfect setup for the last weekend before school starts, it won’t be the worst you’ve ever seen, either.
On and off showers and thunderstorms will continue for Thursday as a front remains stalled to our west and deep moisture resides over the area. We start the day in the mid-70s before highs top out around 90° before showers and thunderstorms fire. Once again, storms could pack heavy downpours that could lead to some flooding in a few spots, so be alert to quickly-changing conditions.
