PRECIPITATION/TEMPERATURE OUTLOOK...  
 
METEOROLOGICAL OUTLOOK...THE PERSISTENT RIDGE OF HIGH PRESSURE  
SETTLES INTO THE FOUR CORNERS AREA OF THE DESERT SOUTHWEST INTO  
NEXT WEEK, WITH AN INVERTED TROUGH OF LOW PRESSURE IN THE MIDDLE  
LAYERS OF THE ATMOSPHERE WORKING INTO DEEP SOUTH TEXAS OFF THE  
WESTERN GULF OF MEXICO THIS WEEKEND. THE ARRIVAL OF THIS  
DISTURBANCE AND AN INFLUX OF TROPICAL MOISTURE AT THE SURFACE WILL  
INCREASE THE CHANCE OF RAIN THIS WEEKEND ALONG THE COAST WITH  
STREAMER SHOWERS AND SEABREEZE CONVECTION INLAND. THE BEST CHANCE  
OF RAIN IS SATURDAY AFTERNOON, WITH DIMINISHING RAIN CHANCES  
OFFSHORE AND ALONG THE SEABREEZE EACH DAY INTO NEXT WEEK AS HIGH  
PRESSURE STRENGTHENS ALONG THE LOWER TEXAS COAST. SEASONAL  
TEMPERATURES MAY DIP A FEW DEGREES WITH INCREASED CLOUD COVER OR  
ANY RAINFALL.  
 
A TRACE TO ONE TENTH OF AN INCH OF RAINFALL IS EXPECTED INTO  
FRIDAY, AUGUST 12TH ACROSS DEEP SOUTH TEXAS, MAINLY ALONG THE  
COASTAL COUNTIES. OVERALL, ABOVE NORMAL RAINFALL IS EXPECTED  
THROUGH SUNDAY, AUGUST 14TH.  
 
NEAR TO SLIGHTLY BELOW NORMAL HIGH TEMPERATURES IN THE MID TO UPPER  
90S AND LOW 100S ARE EXPECTED THROUGH FRIDAY, AUGUST 12TH WITH  
LOWS IN THE MID TO UPPER 70S. OVERALL, ABOVE NORMAL TEMPERATURES  
ARE EXPECTED THROUGH SUNDAY, AUGUST 14TH.  
 
THE LONG RANGE CLIMATE OUTLOOK FOR DEEP SOUTH TEXAS THROUGH  
OCTOBER 2022...DERIVED FROM GUIDANCE FROM THE NATIONAL WEATHER  
SERVICE AND THE CLIMATE PREDICTION CENTER...INDICATES THAT ABOVE  
NORMAL TEMPERATURES ARE GENERALLY EXPECTED FOR DEEP SOUTH TEXAS  
INTO THE FALL WITH EQUAL CHANCES OF ABOVE NORMAL OR BELOW NORMAL  
RAINFALL. THE LATEST MONTHLY DROUGHT OUTLOOK ON JULY 31ST  
INDICATED THAT DROUGHT WILL PERSIST ACROSS DEEP SOUTH TEXAS  
THROUGH AUGUST 2022. THE LATEST SEASONAL DROUGHT OUTLOOK ON JULY  
31ST INDICATED THAT DROUGHT WILL PERSIST ACROSS DEEP SOUTH TEXAS  
THROUGH OCTOBER 2022.
