SCW Saturday update

SCW Saturday update Widespread showers and thunderstorms likely today in Houston. Eric Berger · Saturday, June 20, 2026 11:07 AMIn brief: 🚨 We are issuing a Stage 1 flood alert for Saturday due to the possibility of slow moving storms capable of producing rainfall rates of 1 to 2 inches per hour. Activity should wane this evening, with less coverage on Sunday.*After a fairly quiet start to the day, we are seeing storms firing up along an area of convergent winds near the coast.
*At 11 am CT these storms have formed roughly along a line from Bay City to Pearland to Clear lake to Baytown.
*The heaviest of these storms may briefly produce rainfall rates of 1 to 2 inches per hour.👉 So what will happen during the rest of today? *Our high resolution modeling guidance has not been, to put it politely, great.
*Given the high levels of precipitable water (well above 2 inches for most of the region) we are now leaning toward a fairly active day today in terms of showers and thunderstorms.
*Some parts of the metro area will get hit, while others just hear distant thunder.
*Because some of this activity may be slow-moving, we are going to issue a Stage 1 flood alert through this evening, which indicates the possibility of street flooding.
*Creeks and bayous across the Houston region are generally in good condition, so we don't expect more than nuisance flooding (that is, streets, feeder roads, etc) for today. *This activity could definitely put a damper on outdoor activities.
*Beyond heavy rainfall, there is the threat of thunder and lightning, but no real indication of severe weather such as damaging winds or hail.
*Our expectation is that storm activity will begin to wane this evening and then should die off overnight. *Rain chances should be lower on Sunday, probably in the vicinity of 20 percent.
*Rain chances next week will be near zero, with sunny skies and highs in the mid-90s (at least) as high pressure asserts control.
*So if you're tired of the rain, its end is at hand. Just not quite yet.
