Core of this disturbance appears to be moving through Harris County/Houston Metro at this time. We just came through torrential rains near the house after picking up daughter and grand daughter. Looked at radar and there is a definite turning in the system as we get some of the heaviest rains so far this morning. Still plenty to come per radar too. As stated, it appears that a major portion of the drought area will be alleviated by yesterday's and and today's storms. That is the good news. The flooding that will be/is occurring in some areas is the bad news portion of this.

[srainhoutx]

Storms in Northern Ft. Bend/Waller Counties increasing.

Thus far rain totals from yesterday and today are right about 3" here in Bear Creek. Nasty looking cells on radar may pound us shortly - unless the Dome continues to do its job. What a crazy two days.

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 165 CONTINUES.

HAS MOISTENED DURING PAST FEW HOURS -- WILL BE MONITORED FOR
POSSIBILITY OF ADDITIONAL WW.

BROAD AREA OF PRECIP AND EMBEDDED TSTMS WILL MOVE SLOWLY EWD ACROSS

And I thought my eyes were bugging a few hours ago. Jeez! It's pitch black here in Bear Creek.

[edit] Looking at radar trends, I'm getting extremely worried about training setting up over western Harris county. Can someone tell me I'm just over-reacting?

It is not an over-reaction. This rain stretches all the way to S of SA. It has now set up training from what I see on the radar.and the urban and small stream flood advisory is definitely warranted. I am preparing to go further into skywarn mode and may have to begin reporting from my area. It has been pouring at our house for the last 20-30 minutes with no let up. What I was concerned was going to happen with the massively unstable air mass is apparently beginning to happen and we may be looking at a massive flood event over much of the Houston metro and SE TX area. Please everyone in the Houston metro/SE TX area stay home. The streets will probably begin to fill quickly and become impassable in many areas unless this lets up soon and radar does not indicate that at this time.

Edit: 12.49pm-Our streets are now becoming impassable. The water is higher than I have seen it in a long time here.

Edit: 1:15 pm-Cars flooded out in our streets and the water is higher than every time except one(Allison)that I have seen in the 22 years we have lived in this house. It is still pouring and when I checked the gauge 20 minutes ago we were already at 3.5" and that was probably low due to the location of the gauge. Definitely a major flood event unfolding now in the Houston area. Everyone please be safe. I have already reported to NWS and we were just issued a Flash flood warning for Harris and MOntgomery Counties.
