Rest of the work week: Heat and humidity return

/ May 21, 2024 at 10:21 PM

The forecast for the rest of the work week is fairly straightforward: Partly cloudy to mostly sunny skies with temperatures gradually getting warmer (with dewpoints unfortunately following suit) as time goes on. Wednesday will feature one more cool start in the low 60s before warming to the mid-to-upper 80s in the afternoon. Dewpoints will mix out to the low 60s, so it won’t feel too bad. They’ll start to climb into the upper 60s on Thursday, though, as highs reach 90° in the afternoon. With the additional humidity, expect heat indices to run a few degrees warmer. Friday continues the warming trend, with highs once again in the low 90s and dewpoints creeping up even further to the 70° mark making for another warm and muggy day.

While the rest of the work week looks to remain rain-free, slight shower and thunderstorm chances will figure into the forecast as we head into the Memorial Day weekend. It doesn’t look like a rainout, but you’ll want to have indoor backup plans in case thunderstorms threaten.

Finally, a programming note: I’m taking the next few days off for some much-needed downtime. Posts will be scattershot at best. As always, the latest NWS forecast is on the chswx.com homepage. See y’all next week!
