August Weather Discussion

[weatherguy425]

HGX seems to be the bearer of GOOD news this afternoon!

A WEAK BOUNDARY OVER EAST TEXAS...A DEVELOPING SEA BREEZE COUPLED
WITH PW VALUES AROUND 2.2 INCHES AND TEMPERATURES NEAR 100 DEGREES
WILL ALLOW FOR SCATTERED STORMS TO DEVELOP AND LINGER THROUGH THE
EVENING. AN INVERTED V SIGNATURE SUGGESTS THAT THE STRONGER STORMS
HAVE THE POTENTIAL TO PRODUCE WIND DAMAGE. CONVECTIVE POTENTIAL
CONTINUES TO FIGHT SUBSIDENCE FROM THE EVER-PRESENT UPPER LEVEL
RIDGE. HAVE 30 POPS FOR NOW AND THINK LOW END CHANCE WILL COVER
IT. DESPITE LIMITED COVERAGE...AM STILL RATHER CONCERNED ABOUT
SEVERE POTENTIAL AND MAY ADD SEVERE WORDING TO THE ZFP.

HAVE LEANED TOWARD THE MORE CONSISTENT GFS FOR THE END OF THE WEEK
AND WEEKEND. BY THURSDAY...THE GFS DEVELOPS AN INVERTED SURFACE
TROUGH AND A WEAK 500 MB LOW OVER THE WESTERN GULF. THESE FEATURES
WILL INCH TOWARD THE COAST ON FRIDAY BRINGING CLOUDS...COOLER
TEMPS AND PRECIPITATION. THE INVERTED SFC TROUGH WILL MOVE INLAND
ON SATURDAY BRINGING THE AREA A GOOD CHANCE OF PRECIP AND THE BEST
CHANCE OF RAIN THIS AREA HAS SEEN IN ALMOST 4 WEEKS. SPEED AND
DIRECTIONAL SURFACE WIND CONVERGENCE COUPLED WITH PW VALUES
AROUND 2.4-2.5 INCHES SUGGEST THAT SOME DECENT RAINFALL TOTALS
WILL BE POSSIBLE ESPECIALLY TOWARD THE COAST. 12Z ECMWF NOW
SUPPORTS THE 12Z GFS SO CONFIDENCE IS INCREASING THAT RAIN CHANCES
WILL BE ON THE RISE. 43

I have a gneral question for our weather gurus. As I was growing up my friend's grandmother used to wait for the first night in late summer when the LOW temperature was in the 60's. She would then say "that the back of summer is broken". I remember those days happening in last August or early September. Do any of our gurus know-or can research-what is the average date for Houston to first get a low in the 60's in the fall. I know on the forum we have talked about the 50's, but i'd like to know about the 60's.

I looked at old records and did notice some years there were 60's in July. Also, do you need know 60's from 60 to 69 or 60 to 65?

[BiggieSmalls]

May have 60's in Dallas in a few nights

[svrwx0503]

Pretty rough weather for some across northeastern Ft. Bend and eastern Harris counties.

Numerous trees down in our neighborhood Settlers Way and Hwy 6. During the height of the storm I estimate winds gusts to 65 mph and we had quarter sized hail. Power just came back online 20 minutes ago .... That was one wicked storm. Visibility was cut to zero at the height of this storm as well.

[txflagwaver]
