One of the driest Aprils on record will come to a somewhat unsettled end this week as the pattern starts to finally flip toward something a little more favorable for rain chances. We’ll run a little cooler, too, especially as we start May.

Weekend forecast: Storms return, but don’t expect much rainfall

/ April 24, 2026 at 11:04 PM

The main weather story for the weekend will be a cold front that’ll move into the area later Saturday, which will help to bring about the first significant rain chance in weeks. A few short-lived seabreeze thunderstorms got close enough to produce a trace of rain at the airport today — the first non-zero rainfall recording at the airport since April 6 — but the unmeasurable sprinkles have kept April 2026’s rainfall total at 0.01″ as we head into the month’s final week, currently in a tie with 1972 for the driest April on record.

Friday & the weekend: A little much-needed rain Saturday night into Sunday

/ April 23, 2026 at 11:53 PM

After one more mostly sunny and dry day Friday, the pattern finally turns a little more unsettled starting Saturday as a cold front advances toward the area. This front will help stir up some showers and maybe some thunderstorms later Saturday into Sunday. Rainfall amounts will generally be light — a quarter-inch may be awfully generous from this setup — but everything helps.

Temperatures Friday and Saturday run in the mid-to-upper 80s in the afternoons after starting in the upper 50s Friday and the low-to-mid-60s on Saturday. From there, a backdoor cold front looks to sink southward across the area on Sunday, which will take temperatures down a few degrees with highs in the low-to-mid-80s expected. With the exception of Monday, though, generally expect warmer-than-normal temperatures to close out April.
