TRACKING INVERTED TROUGH OVER NORTHWEST MEXICO WHICH WILL EVENTUALLY BECOME A PLAYER IN OUR WEATHER WEDNESDAY AFTERNOON THROUGH THURSDAY MORNING. THE DILEMMA FOR WEDNESDAY WILL BE THE AMOUNT OF DEBRIS CLOUDS POTENTIALLY STREAMING OVERHEAD FROM DECAYING CONVECTION OVER ARIZONA TONIGHT. THE CLOUDS MAY ACT TO INHIBIT SOLAR INSOLATION THUS LIMITING INSTABILITY. SO WILL BE MONITORING THAT DAY TO DAY.

ON WEDNESDAY HOWEVER...THE MONSOON MOISTURE WILL BE CONTINUING TO MOVE INTO THE FORECAST AREA WITH THE GFS INDICATING PWAT VALUES BY 00Z THURSDAY OF NEARLY 2 INCHES ACROSS SOUTHERN MOHAVE AND EXTREME SOUTHEAST SAN BERNARDINO COUNTY. THIS COUPLED WITH THE EASTERLY WAVE/NEGATIVE LI VALUES FROM ROUGHLY DAGGETT CALIFORNIA TO CALIENTE NEVADA WILL RESULT IN ISOLATED TO SCATTERED THUNDERSTORMS ACROSS MUCH OF MOHAVE...THE SOUTHEAST PORTION OF SAN BERNARDINO... CLARK AND LINCOLN COUNTIES WEDNESDAY AFTERNOON/EVENING. AS THE WAVE CONTINUES NORTH OVERNIGHT...ISOLATED CONVECTION MAY CONTINUE THROUGH THE NIGHT. BY THURSDAY...WITH THE WAVE SHIFTING OUT OF THE AREA...THE GFS INDICATES THAT MOISTURE IS DRAWN A LITTLE FURTHER EAST WITH THE MAIN FOCUS BEING MOHAVE/CLARK/LINCOLN COUNTIES. TEMPERATURES WILL CONTINUE TO BE ABOVE NORMAL TODAY...BUT WITH THE INCREASE IN MOISTURE/CLOUDS EXPECTED WEDNESDAY AND THURSDAY... ESPECIALLY OVER THE SOUTHEASTERN HALF OF THE FORECAST AREA...

WE MAY GET ANOTHER LITTLE MOISTURE PUSH TOWARDS THE END OF THE WEEKEND AS MODELS DEPICT A MINOR DISTURBANCE APPROACHING FROM THE EAST...BUT AT THIS POINT ANY ADDITIONAL MOISTURE ADVECTION LOOKS MINIMAL. TEMPERATURES WILL BE AT OR SLIGHTLY ABOVE NORMAL FRIDAY THROUGH MONDAY. .AVIATION...FOR MCCARRAN...SOUTH/SOUTHWEST WINDS OVER THE NEXT 24 HOURS...WITH GUSTS AROUND 20KTS ON AVERAGE DURING THE AFTERNOON/EARLY EVENING. CLOUD COVERAGE WILL BE MINIMAL WITH ONLY FEW CU POPPING UP TO THE EAST. TEMPERATURES ARE EXPECTED TO BE AT OR ABOVE 100F BETWEEN 20Z AND 02Z TODAY.

THERE STILL IS SOME CONCERN WITH DRY THUNDERSTORMS ESPECIALLY ON THE WESTERN EDGE OF THE EXPECTED MOISTURE BOUNDARY ON WEDNESDAY WITH MORE MOIST STORMS FURTHER EAST.
