Another shortwave is rounding the base of the upper trough well to our West. A little daytime heating tomorrow may offer additional chances for heavy showers and thunderstorms further South. There are going to be outflow boundaries all across the Region from down near Laredo on East. Unless the WPC changes their mind, there is a Moderate Risk for Excessive Rainfall tomorrow a bit further S down to the Coast. I'm going back to sleep. Great job everyone while we were away at Conference on letting folks know what was possible regarding our sensible weather. Many of the Meteorologists committed on how well we operate and pass along good and reliable information to those that follow our Weather Forum. Kudos gang on a job well done!!

Update from Jeff:

Flash Flood Emergency for Waller and NW Harris County until 445am.

THIS IS A LIFE THREATENING SITUATION.

Rainfall of 7-10 inches since 600pm is resulting in a dangerous flash flood event. Numerous high water rescues are in progress and homes are flooding from both channels exceeding banks and intense short duration rainfall rates overwhelming local drainage systems. A couple of watersheds are at or above their 100-yr water level elevations.

Forecast:
See no end really to this event as moisture continues to flow off the Gulf into this line of slow moving excessive rainfall and the air mass has not been worked over. Could easily see another 5-7 inches on top of what has already fallen…which will be devastating. Areas along and just north of I-10 from Columbus to I-45 will continue to be hit over and over. Storm totals could approach 12-15 inches in this area.

Actions:
Stay where you area…do not attempt to travel at this time anywhere in NW Harris/Waller Counties. Even if water is in your house stay where you area…you are safer in your house than traveling on any roads that area flooded.
