Not sure if you can see the green line in the image ticka1, but it barely does include part of SE TX. Concerned about a training event setting up.

My area has been getting wave after wave of brief but very heavy rain since about 5:30 this morning. Lucky we get a big enough break for the puddles to go down a bit before it begins to rain again....

[weatherguy425]

Interesting to see the band near Victoria work it's way back UP the coast, towards us.

Most models agree that the 594 ridge builds back over Texas by mid-month. If that forecast holds, then conditions revert to what they were in June- very hot and much drier.

ASTRONOMICAL HIGH TIDE RESULTS IN CURRENT WATER LEVELS OF 2.8 TO
3.8 FEET ALONG THE SHORE OF GALVESTON BAY AND THE GULF FACING

[ticka1]

Are the rains over for us here in SE Texas?

[srainhoutx]

I suspect enough moisture to fire off at least scattered storms. Convective temps in the mid 80's...

[biggerbyte]

Based on radar returns from offshore, no, there is more coming a few hours from now. We'll see if it actually holds up.

[Ptarmigan]

Just thinking back to the post a page or two back, a connection between the Top 10 wettest July's and Texas hurricane activity.


Seems to make sense, a wet July might be the product of tropical waves or disturbances coming to visit, indicative of a pattern favoring flow into Texas from the tropics, which might mean something in another month or abouts when the frequency of Atlantic Basin storms starts to increase.


For now, a drying trend, as seen graphically on this image from wxmaps.org

I am the one who wrote about the connection between Upper Texas Coast hurricane activity and top 10 wettest July's. I got Upper Texas Coast monthly rainfall total fro July from 1895 to 2009 and found a rather strong correlation for major hurricanes making landfall from August to September. I am still checking to make sure I did not enter the data incorrectly.

WAS LEANING TOWARD CANCELING THE FLASH FLOOD WATCH THIS EVENING...BUT
WITHIN THE PAST HOUR THERE HAS BEEN AN INCREASE IN ACTIVITY OFF THE
COAST. NOT SURE HOW MUCH OF THESE SHOWERS AND THUNDERSTORMS WILL MAKE
IT ONSHORE AS A DRIER AIRMASS CONTINUES TO WORK THIS WAY FROM THE EAST...BUT
IF THEY DO THEY COULD POTENTIALLY ADD MORE RAIN TO OUR VERY SATURATED
GROUNDS. SO WILL HOLD OFF ON THE CANCELLATION FOR NOW. 42

I see rain offshore, but they are scattered at best. Not widespread like earlier today.

Not sure that the report is accurate. Looking at the hourly obs from Bergstrom, the low for last night appears to be only 76.

Could be between hours, and AUS is now in a bit of a valley associated with the Colorado River, and cool air sometimes drains down into the valley.

New record lows will be set on a fairly regular basis the next few years (2004 was the new site) after moving the official site from the old, more representative Mueller Airport location a few years back.

Yes, but when they show the high and low temps for the previous 6 hours, the lowest temp shown is still 76.

You're most certainly right, I don't see where it says that either.. Strange?? Maybe the meteorologist on duty needed glasses to see it wasn't 66, rather, 76? lol.. Not to mention, the last RER listed on the NOAA site is from 1/9/2010 when it dropped to 17 degrees..

EWX sent a message to the media citing the record error-

There was an inaccurate reading ingested into the climate program before the morning climate run. The actual low temp was 73 at 504am. Sorry for the error.
