JUNE 2016: Showers/Storms Possible

[Katdaddy]

Just got home from downtown Houston. Very intense rains in downtown with gusting winds especially between the buildings. The rain stopped just S of downtown and skies were partly cloudy down I-45 to League City. Picked up .39" earlier this morning.

[srainhoutx]

It appears locations across Northern Harris and Montgomery Counties have already received over 3 inches of heavy rainfall this afternoon basically where the Flood Warning was earlier. Will need to monitor developments throughout the night into tomorrow morning very carefully.

Jeff reporting 4.24 inches of rainfall Spring Creek @ I-45

[TexasBreeze]

Cypress Creek in NW Harris County is bound to rise again being it was already half way or so full.

[srainhoutx]

Jeff reporting 6.0 inches of rainfall in 2 hours over Spring Creek.

Jeff reporting Cypress Creek @ 249 rising rapidly.

Rainfall at DW Hooks over the last 6 hours totals 3.29 inches. Conroe received 2.37 inches since 1 PM.

[Andrew]

Expect similar situations as we experienced today over the next couple days, but wider coverage over most of the region. Some areas are going to get a lot more than others as it was today.

[Rip76]

Nothing like the site of a tropical atmosphere.
Low dark clouds, with the sunlight reflecting off the towers.

I remember how depressing 2011 was, with not a cloud in the sky.

[TexasBreeze]

That cell is just stalled out and dumping copious amounts of rain I am right under it!

Lastest rainfall. Spring Creek and Cyprus Creek is about to go out of its banks.

[Andrew]

latest from Jeff

Slow moving to nearly stationary cluster of excessive rainfall pounding NC Harris County.

Rainfall totals up to 6 inches in 3-hrs on lower Spring Creek and 3.5-4.5 inches on middle and lower Cypress Creek. Significant rise is in progress on Cypress Creek and overbank flooding is likely on this channel this evening from Stuebner Airline downstream to the confluence with Spring Creek.

Watching excessive rainfall training over upper headwaters Greens Bayou NNE to southern Montgomery County. An additional 1-3 inches on top of what has fallen will be possible.

Significant street flooding is in progress across much of north and north-central Harris County.

Willow Creek: should crest below bankfull
Lt Cypress Creek: crest below bankfull

Spring Creek: likely to crest near floods stage at I-45.

W Fork San Jacinto River: river is already overbanks and is starting a new rise. Could see renewed moderate flooding, but not expecting major flooding with current rainfall.

Another one

"Flash Flood Watch in effect for all of SE TX until Friday evening.

***This is a potentially dangerous flash flood event for the state of TX***

If anyone needs to see the ability of this air mass to produce extreme rainfall totals…6 inches in 3-hrs over Spring this evening should be proof.

A slow moving upper level low will drift into TX Thursday and stall across SC and SE TX Thursday through Saturday before shearing out to the NE. Air mass is already tropical with PWS of 1.8 inches plus and a saturated profile. Overall nature of the event will transition the upper level feature to a warm core mid level feature as the low sits and spins in a tropical air mass. Low will gradually take on tropical type characteristics. Setup is highly favorable for excessive rainfall and flash flooding given deep layer tropical moisture, slow storm motions, focusing boundaries, and good upper level divergence. This all points to high rain chances and flooding rainfall. Such “tropical” type systems like to focus their heavy rainfall in the overnight hours…so this will be something to keep an eye on over the next 2-3 nights.

As usual the fine details will determine the areas that see the “large rainfall totals” and they could certainly be very high given 2-3 inch per hour rates that could last a few hour or longer. Small scale boundaries will determine where such rainfall occurs.

Will go with 3-5 inches widespread across much of the area with isolated totals of 8-12 inches. Could even justify higher totals than that given the air mass and what we have seen over the last six weeks.

Rainfall of this magnitude on saturated grounds and flooding watershed is placing the region in a dire situation. There is simply nowhere for the water to go and run-off will be maximized across the region. I am very concerned with the potential for new and worsened river flooding and flooding on the creeks and bayous in Harris County. "

Severe winds are looking possible along the Beltway headed towards Crosby. Currently at the 59/Beltway intersection.

Getting dumped on right now, which with the rain that's looking possible over the next couple of days, is definitely not needed. Stay safe everyone!
