THURSDAY, 23-JUL-09, MORNING REPORT

A GOOD AMOUNT OF UPPER LEVEL MOISTURE MOVED INTO OUR FORECAST AREA THIS MORNING, CREATING MOSTLY CLOUDY SKIES IN SOME AREAS. EVEN THOUGH ACTUAL THUNDERSTORM ACTIVITY HAS REMAINED LOW, I CAN'T RULE OUT AN ON-GOING CHANCE FOR BOTH THE OWENS VALLEY AND MONO COUNTY THROUGH TODAY. FOR FRIDAY AND INTO THE WEEKEND, HIGH PRESSURE WILL REMAIN OVER THE FOUR CORNERS AREA AND THIS WILL RESULT IN A MOIST SOUTHEASTERLY FLOW WITH A CONTINUING THREAT OF SHOWERS AND THUNDERSTORM ACTIVITY. TEMPERATURES FOR THE WEEKEND WILL CONTINUE TO BE ON THE HOT SIDE. RIGHT NOW AT LEAST, MONDAY THROUGH THURSDAY LOOKS LIKE A DOWNWARD TREND IN THUNDERSTORM ACTION.
