Forecast update - flood threat With the potential for slow-moving storms, we are issuing a Stage 1 flood alert for Saturday in Houston. Eric Berger · Saturday, June 6, 2026 8:32 AM In brief: 👉Due to wet soils and the potential for slow moving storms, we are instituting a Stage 1 flood alert for the Houston region through Saturday evening.
👉Please be weather aware and mindful of the potential for high water on roads. 👉 SATURDAY - *Looking at the radar at about 8:30 am CT, things are largely quiet with the exception of a few showers over Galveston Island.
*However with a moisture-laden atmosphere, we expect to see the development of widespread showers and thunderstorms later this morning and lasting through the afternoon hours. 
*To be clear, rivers, creeks, and bayous within the Houston metro area are all within their banks.
*However for much of the region, particularly central Houston, our grounds are saturated such that any additional rainfall today will quickly run into streets.
*Therefore we are likely to see street flooding develop more quickly than normal. *In terms of rainfall, for most of Houston, things will be just fine later today.
*However atmospheric conditions are supportive of heavy rainfall, and today we expect some storm motions to be slow.
*Therefore whereas most of the region may see a few tenths of an inch of rainfall, parts of the area may see 3 or more inches.
*The best chances for heavy rainfall today appear to be in Harris County, but the suburbs are also at risk. 
*Given all of this, we think there is a decent chance of some street flooding (i.e. low-lying roads, some feeder roads, etc.) today where rains are heaviest.
*Please be weather aware this afternoon and take more time during rain storms. 👉 SUNDAY - Conditions should dry out overnight, but some additional storms are possible on Sunday, albeit not to the extent we think the Houston region will experience today.

845AM radar - A few storms have formed north of Houston but that's about it at the moment.

StormChaser : The east side of Kingwood received heavy rain yesterday whereas the front of Kingwood had much lighter rain. Hopefully today we get more rain but not flooding.

New Meso Discussion for our area until 5pm. Sorry for the sloppy copy/paste. 👉2 to 3+ inches of rain in an hour. Mesoscale Precipitation Discussion 0338
NWS Weather Prediction Center College Park MD
1217 PM EDT Sat Jun 06 2026 Areas affected...southeastern TX into far western LA Concerning...Heavy rainfall...Flash flooding possible Valid 061616Z - 062200Z SUMMARY...Isolated flash flooding will be possible across portions
of southeastern TX into far western LA through the afternoon.
While the coverage of any flash flood issues should stay limited,
there will be the potential for very high rain rates in excess of
2 to 3 inches per hour. DISCUSSION...GOES-E visible satellite imagery at 16Z showed the
early stages of scattered showers/thunderstorms over the upper TX
Coastal Plain, along with a southward sinking outflow boundary to
the north which extended from Williamson to Walker counties. The
cells were moving with the mean layer flow at 10 to 15+ kt toward
the northeast, of a similar orientation to the low level flow,
supportive of at least short term training. The environment was
very moist with PWs of 2.0 to 2.2 inches along with MLCAPE of 1000
to 2000 J/kg (SPC mesoanalysis, satellite blended TPW and GPS
ground-based sensors). While no obvious axes of SW to NE low level convergence (oriented
with the mean wind) are seen in the short term high res guidance
through the afternoon, the potential for brief backbuilding and
training will still exist over the next several hours. Diurnally
driven convection with the added component of convergence with the
southward sagging outflow boundary will maintain scattered showers
and thunderstorms well into the afternoon. While much of this
region of TX is usually able to handle high rain rates without
problems, recent days of localized heavy rainfall have lowered
flash flood guidance values into the 2 to 3 in/hr range across
several locations. The lowered FFG combined with potential for
urban overlap and high rain rates is enough to warrant a
limited/isolated concern for flash flooding due to 2 to 3+ inches of rain in an hour. ...
