Short fused Flash Flood Watch issued for this morning to cover this ongoing overnight event. Be careful on the morning commute. Multiple flooded roads are being reported.
...FLASH FLOOD WATCH IN EFFECT UNTIL 8 AM CDT THIS MORNING...
The National Weather Service in Houston/Galveston has issued a
* Flash Flood Watch for a portion of southeast Texas...including
the following counties...Brazoria...Chambers...Fort Bend...
Galveston...Harris...Liberty and Wharton.
* Until 8 AM CDT this morning
* A mesoscale convective vortex (MCV) is producing heavy rainfall
across much of Southeast Texas this morning. Over 6 inches of
rainfall have already fallen across portions of Harris County,
with additional steady moderate to heavy rainfall expected
through the rest of the morning. A developing line of showers
and thunderstorms extending to the west into Central Texas will
swing around through the watch area this morning, creating the
potential for additional flash flooding across the watch area.
The watch may need to be extended depending on the evolution of
this system through the next several hours.
* Do not drive your vehicle into areas where the water covers the
roadway. The water depth may be too great to allow your car to
cross safely. Vehicles caught in rising water should be
abandoned quickly. If your vehicle stalls...abandon it and seek
higher ground immediately. Rapidly rising water may engulf your
vehicle and its occupants and sweep them away. Move to higher
ground.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.
You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.

The phrase for the Houston metro rush hour this morning……….”Turn around don’t drown”.
The mesoscale convective vortex (MCV) ignited very heavy rains late yesterday evening that have continued overnight and continue this morning with some areas receiving over 8” of rain. Flash Flood Warnings continue for the Houston metro area as the rains begin to slowly decrease. Additional rain may re-develop later this afternoon as the MCV drifts across the area.

Thanks djjordan for the overnight updates. Tuesday morning briefing from Jeff:
Excessive rainfall and flash flood event has impacted Waller, Fort Bend and Harris Counties overnight.
Widespread street flooding continues over large areas of western and northern Harris County into Waller and Fort Bend Counties.
Rainfall amounts averaged 5-6.5 inches in the last 6 hours from Jersey Village to Katy with a wider area of 3-4 inches from Kingwood to Sugar Land to Waller.
Numerous creeks and bayous are very high with a few having exceeded their banks:
Greens Bayou at US 59
Brickhouse Gully at Costa Rica
South Mayde Creek at Greenhouse
Keegans Bayou at Roark
Halls Bayou at Airline
Rummel Creek at Brittmore
Mid level system responsible for the overnight rainfall is centered near Hempstead and continues to spin, but rainfall intensity has been gradually subsiding with the main band located just SE of this feature. There has been some continued moderate rainfall across northern Fort Bend County, but this rainfall has not progressed much into Harris County. Until the mid level system moves east of our area the threat for additional heavy rainfall will remain in the forecast, but not expecting as organized as overnight.
For the next few hours residents from Jersey Village to Katy should remain in place and only travel if absolutely needed.

The pattern screamed heavy rain yesterday evening looking at the low spinning and building convection. The NWS extended the watch through Wed morning due to the low hanging around one more day and night with daytime heating and nighttime convergence setting off more storms later possibly.
It's spinning right over The Woodlands area now...
At noon, Brooks said the Low was east of Conroe, but there's no breeze or High pressure to push it anywhere. So, it's just drifting. The HRRR showed the east side getting it, tomorrow.houstonia wrote:I heard a forecaster say that the low was going to drift back over town and we are due to get more heavy rain. I just wanted to see if that's the general consensus here?
thanks.
Probably the better answer is 'stay tuned,' because it's a fluid situation (no pun intended).
Round 2?

Looks like the center has shifted a bit east towards Livingston now, so maybe we will be spared the heaviest rainfall, at least for now. Question is where does the MCV drift overnight? Does it keep moving slowly to the east, sparing the Houston area, or will it retrograde back to the west.
Update: NWS says it will drift SE and then Northward overnight.
