July 2016: Summertime Pattern To End July

[Cromagnum]

Nothing again this morning. Everything is north or south. My area of town south of Pearland always gets the shaft.

Every storm headed towards my house broke up and went SW and SE of us. I hope we get some tomorroe then.

My backyard killed another storm cell last evening. 2 for 2. Still a trace of rain. We'll see what today and tomorrow serves up.

I would think that rain which develops this afternoon would be less widespread than yesterday since the big area of rain in the gulf is sapping moisture inflow. Correct me if I am wrong.

[davidiowx]

It is really coming down in Stafford and has been for a good 20-30 minutes now. I just hope the same is happening at my house lol..

[jasons2k]

Worried the outlfow boundary is going to spoil it for me again!

[Montgomery]

Concrete pour scheduled for 4:00 a.m tomorrow in The Woodlands. To pour or not to pour??

[cperk]

I've received 1.5 inches at my home in Richmond today.

[jasons2k]

Another day, another tease up here as the plants slowly shrivel up more each passing day...

[Rip76]

Really coming down in Stafford.

[cperk]

Concrete pour scheduled for 4:00 a.m tomorrow in The Woodlands. To pour or not to pour??

My best guess is that the crew will probably cancel that pour.Concrete needs several hours to set up enough to repel rain drops.If it's a small pour it can be covered.

[bikerack]

Receiving the first measurable rain at my house in Kingwood since 6/6. Awesome!

[Cromagnum]

I need to just set my yard on fire. EVERY round of rain has completely dodged the Rosharon area.

I need to just set my yard on fire. EVERY round of rain has completely dodged the Rosharon area.

I feel your pain, I really do. Nothing like fertilizing before a summertime ULL plows through and not getting a drop...

Tuesday evening briefing from Jeff:

Region has fallen into an active pattern with scattered to numerous slow moving showers and thunderstorms over the last 48 hours.

Upper level ridge has retreated to the west with another upper level ridge located over the SE US. The weakness in the height fields between the ridges of high pressure located over coastal TX into LA is responsible for the recent increase in rainfall production. Combined with the flow of deep tropical moisture into the region with PWS of 2.0+ inches and upper level disturbances moving east to west along the coast has produced some good rains over the area…especially along and south of I-10. Surface trough located across the northern Gulf coastal waters continues to be the focus for nocturnal storm development across the nearshore waters which then spread inland during the day as heating increases the inland instability. Surface trough should begin to lift northward tonight and expect another round of early morning storms on Wednesday.

Short range guidance is showing a fairly strong signal at storms blowing up around Galveston Bay after 300am and starting to progress inland in the 500-700am time period. Such pattern is favor in these tropical air masses which like to focus convection near the coast early in the morning hours. Exactly how far inland the activity will translate on Wednesday is highly questionable as many times the coastal morning activity will work over the incoming air mass and prevent inland storms…but that was not the case today and storms were able to regenerate once temperatures warmed into the upper 80’s.

Rainfall rates will continue to be 1-3 inches in an hour or less under the strong cells and slow storm motions. Places around Hobby Airport saw upwards of 5.52 inches of rainfall today and this type of rainfall is not uncommon in this sort of air mass. Good news is that storms will remain short lived and not widespread suggesting that locations that see the excessive rainfall will be isolated. Where that happens street flooding is almost certain.

Upper ridge attempts to build across the weakness or “break” between the high pressure cells, but never really gains full control like it did for much of July. Will maintain at least a 30-40% rain chance for daily heat of the afternoon storms Thursday into the weekend. Appears the ridges may break again early next week with another westward moving upper level feature helping to redefine the weakness and bump rain chances again next week. Overall pattern keeps the area in a more typical summer pattern of scattered showers and thunderstorms moving inland from the Gulf daily and more reasonable high temperatures in the lower 90’s. It also places the area unprotected from any sort of tropical formation caught in the east to west steering flow. This is in large contrast to the recent summer August patterns with strong high pressure over TX which kept rainfall to a minimum and tropical cyclones to our south or east.

Was another long messy commute home from work, was worse than yesterday, even though the rain was less than yesterday when I left the office. Probably residual from the earlier deluge. I do find it amazing that I work in the Westchase area, was not raining, live in Stafford, relatively close, such a difference in the amount of rain. It was not raining at all by the office, but when I hit Bellaire on the Beltway it was. Had to drain the pool when I got home also. Lots of moisture in Stafford the last few days.

A beautiful rainbow downtown after the first round tropical downpours this morning.

[DoctorMu]

Finally, an afternoon shower breaks through the Aggiedome, FTW. 0.4 in of precip IMBY.

First measurable rain since June 28!

Still better than 2011! (notice I set the bar pretty low). Trees and grass in decent shape.
