2023 Memorial Day Weekend Forecast in San Antonio

Hit-or-miss storms are possible on Monday

Memorial Day forecast in San Antonio (KSAT)

The unofficial start of summer kicks off this weekend as Memorial Day approaches. While it won’t be for everyone, there is a chance for a few showers and storms on Memorial Day itself.

Here’s what you can expect:

Memorial Day (5/29)

  • A disturbance will roll across the state on Monday, sparking up widely scattered, hit-or-miss showers and storms
  • Coverage will be about 30-40%
  • This is important to keep in mind: it will not be a washout for everyone, and some will miss out on the rain entirely. But, if you happen to get a thundershower, localized heavy rain with minor flooding is possible
  • Overall, don’t cancel your plans, but if you do have any outdoor activities planned, have a backup option to briefly move things inside if you come across a passing shower or storm
  • Large, damaging hail is NOT a concern
  • Temperatures will start off in the upper 60s Monday morning before climbing into the low/mid 80s Monday afternoon

We’ll be keeping our eyes on the forecast for you! The latest updates can be found on-air, online, and on the KSAT Weather Authority App.
