Looks like some heavy rains setting up and training over Brazoria, Ft Bend and Western Harris counties this morning.

That's some deep fetching of Gulf moisture. Got dark enough before the skies opened up that the street lights and neighbors' outdoor lighting kicked on. Pretty efficient rains to the point street was somewhere between 1/3 to half covered in water.

WPC has added the area to a slight risk for flooding.

Don, what do you make of the overnight Euro? Possibility of another cut off low next week?

I think it could be on to something as we keep getting these western troughs moving in from the pacific with ridging building over top.As long as we stay in this pattern its only a matter of time before we have another cutoff low. Fwiw the Canadian has the cutoff low also but its much further to the west than the Euro shows.

Flash Flood Watch extended slightly E to include the Houston area:

...FLASH FLOOD WATCH IN EFFECT UNTIL 9 PM CDT THIS EVENING...

The National Weather Service in Houston/Galveston has expanded
the

* Flash Flood Watch to include a portion of southeast Texas...
including the following counties...Austin...Coastal Brazoria...
Fort Bend...Grimes...Inland Brazoria...Inland Harris...
Montgomery...Waller and Washington.

* Until 9 PM CDT this evening

* Another round of moderate to heavy rain and isolated
thunderstorms can be expected across parts of Southeast Texas
through this evening. A band of storms this morning from around
Freeport feeding up into Fort Bend and Harris counties will
continue to do so through early afternoon. Training of storms
will be piling up the rainfall in these areas and rainfall
totals of 2 to 3 inches will be common with isolated totals in
excess of 6 inches. The flood threat will be strongly dependent
on the location of the heaviest precipitation axis. If any
heavy rain falls on already saturated grounds, flash flooding
can be expected.

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.

I can't help but hear Les Miz' "One Day More" as background music when I read this

From the article - after this weekend: "but for now I’m thinking we’re going to enter a mostly dry pattern that will become difficult to break."

We'll see...

I know that’s what you need but I’m not so sure that’s going to happen. I’d put my money on it staying wet right now. I know Thursday and Friday of this week should be dry though but no telling after that.

I wonder if the NAO or AO has anything to do with these systems being blocked or cutoff? Are they positive which is where we’re getting the blocking from?

[Cromagnum]

Several rounds (and counting) hit my house today. Very heavy rainfall.

[jasons2k]

There isn’t a ‘blob’ in the gulf to cutoff the inflow....the band keeps backbuilding. It’s the sleepers that always get us...

A waterspout was sighted offshore from Surfside earlier.

have fallen. Flash flooding is ongoing or expected to begin
shortly. A band of storms continues to bring heavy rainfall to the
area and these storms will be tracking across areas that have
already been hit by earlier rainfall. Rainfall rates of nearly
3"/hour will be likely with these storms. Street flooding will
likely we worsening across the area.

HAZARD...Flash flooding caused by thunderstorms.

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, urban areas, highways, streets and underpasses
as well as other drainage areas and low lying spots.

12z Euro suggests maybe another cut off low pressure system for next week, we may get a day or two of drying but im thinking the pattern might stay wet for a while

I think once we get past Friday it’s kind of a question mark. For now I’d go with a 20-30% chance of rain from Saturday through the end of the forecast period. Right now it doesn’t look like that possible low next will be close enough to us to produce anything significant besides a few scattered showers. Now in west central TX, that’s a different story. The bullseye is on them at least for now.

[Stratton20]

We definitely will have to watch it, anything beyond 5-6 days is pretty unreliable

Potentially, I'm seeing nearly an inch of rain a week for the next 2 weeks on the models. Looks relatively unsettled.

Fine with me.

Seems like a safe bet through June 10th.

Hope this high pressure ridge dorsnt stick around long, I love this rainy weather

[TexasBreeze]

Looks like a training band west to east is setting up from Fayette to Harris County (along just north of I-10.

[davidiowx]

Sheesh that storm out south of Brenham near Bellville is just dumping rain. That’s a flash flood nightmare if it were in the suburbs or inner city.

[MontgomeryCoWx]

If it rained every day in the Summer, I wouldn't complain. Can it stay in the 80s all Summer, and then stop raining when CFB season rolls around with the first major cold front? That's not too much to ask is it?
