Nothing here since this morning

1.94 for the past 24 hours in my rain bucket while just on the other side of 290 near Jones Rd and FM 1960, 4.2 inches have been measured so far.

loving the humidity, not so sure I'll be loving the mosquitos though

Anyone notice the nice little blob just sitting off the mid-coast this Morning? Didn't some modles hint at some sort of western gulf tropical development this weekend?

That's the Coastal wave of low pressure that we've been talking about developing today. The guidance bring that feature ENE along the stalled frontal boundary currently sitting along our Coastal Counties later this evening into tomorrow as the upper low currently near El Paso slides slowly E across TX during the day tomorrow. PW's, or available moisture remain rather high to our SW and W in the 2.2 range while some drier air has filtered in from the NE across our Eastern area. Rain chances should begin to increase overnight into tomorrow area wide as these features move across the area ending our rain chances. There maybe some isolated showers for a few folks on Tuesday as another upper air disturbance drops SE in the NW flow aloft and a weak Pacific front passes the area.

I am hapy for those that got rain, but so far we have been skunked in League City.

Hopefully, we will get something tomorrow so I can give the sprinklers a break. Although
not as dry as last year, it has still been a very dry summer down here.

[Katdaddy]

I hear ya Canebo. We got a little rain earlier in the week. Picked up .64" for 2 day total which I will gladly take. Actually glad it has turned out by nice sunny day. Getting ready to go the Magnolia Creeks trails and check the progress on the Enterprise NGL pipeline being put in along the Centerpoint right away. Tomorrow may be our day for heavy rain in League City.

[Belmer]

This would be a classic Texas winter storm if it were only 50 degrees colder and one of these were to set up in January/February.
....sigh.... only a few more months....

[unome]

another couple days of rain on tap - mow your lawn while you can, helps to keep the mosquitos down

"Widespread rainfall will be moving into and across the region this afternoon and tonight. Heavy rainfall will be possible and some spots may see as much as 3 to 4 inches of rain."

The short term rapid refresh meso models including the HRRR and RAP are beginning to suggest heavy rains and storms developing around 21Z across the area and continuing overnight into tomorrow. The 16Z RAP is suggesting the Coastal low will be near the Upper Texas Coast in about 18 hour and the 4km HIRES NAM is very suggestive that the upper low near the Big Bend will pass directly over SE Texas with showers/storms wrapping around the eastern half of that feature tomorrow. It appears we are nearing convection temps and the morning daytime heat along with high PW’s near the 2.2 range will provide for a heavy rainfall potential with rainfall rates in the 1-2 inch per range as all the features move closer to the Upper Texas Coast.

[srainhoutx]

The Euro has now picked up on the Western Gulf disturbance E of Brownsville and heads it NE near the Upper Texas Coast tomorrow before moving inland along the Central Louisiana Coast on Tuesday.

I think I'd better turn on the sprinklers. Doesn't look like much for us down South

I feel your pain. No rain again in the League City desert!

Maybe tomorrow.....hmmm, seems like I have said that quite a bit lately.

[jasons2k]

I had a heavy shower earlier today that gave me a quick .40" in about 15 minutes. Just some on and off light rain since.

I also just checked my rain spreadsheet for the year, and I'm a bit lower than I thought. 31.44" for the year so far, most of it from only 5 events (Jan 9 & 25, Mar 11/12 , June 9, & July 10-19).

[wxman57]

Got 0.57" in a storm last evening. Total for year 54.60".

[srainhoutx]

Morning e-mail from Jeff: (note: a little over 3.25 inches in my rain bucket for this event so far and nearing 41 inches for the year to date)

Upper level storm system responsible for the weekend rainfall will move east today.

Upper level storm is centered just west of Houston this morning with radar showing numerous showers developing on the eastern flank of this feature from Montgomery County SSW into Fort Bend County. Main moisture axis and large swath of rainfall has moved east of the area and is focused over southern Louisiana on the northern flank of a NE moving coastal low pressure system. Upper level low should move overhead this morning and begin to exit eastward this afternoon. Fairly extensive dry air is noted just west and southwest of the region and this should progress into the area by early afternoon. It will be possible that with lingering moisture any possible heating this afternoon that a few additional thunderstorms could develop directly under the cold pool aloft, but this possibility appears low at this time as the air column should be drying.

Cold front over the central plains this morning will sweep southward behind the upper level storm and cross the area on Tuesday bringing in a very dry air mass and cooler temperatures. Under clear skies each night temperatures will fall into the mid to upper 50’s and highs in the mid to upper 80’s with low humidity. There will be little change in this pattern until maybe next weekend when another frontal boundary approaches the area.
