KEY MESSAGES
* TEMPERATURES CONTINUE TO WARM THROUGH SATURDAY.
* INCREASING CONFIDENCE IN CLOUDS, RAINFALL, AND COOLER READINGS
SUNDAY THROUGH TUESDAY AS TROPICAL MOISTURE SPREADS NORTHWARD.
A WEAK RIDGE WILL KEEP TEMPERATURES ON THE WARM SIDE WITH HIGHS UP
TO 5 DEGREES ABOVE AVERAGE (MID 90S TO LOW 100S IN THE DESERT
VALLEYS) AND LOWS AROUND 5 TO 10 DEGREES ABOVE AVERAGE (THE 70S).
THIS PATTERN BREAKS IN THE LATE WEEKEND LEADING TO COOLER CONDITIONS
AND BUILDING CLOUD COVER ALONG WITH INCREASING HUMIDITY AS A DEEP
TROUGH APPROACHES THE AREA AND PULLS MOISTURE FROM THE SOUTH.
MODEL AGREEMENT IS REALLY IMPROVING ON THE TOUGH DIGGING INTO THE
REGION INTO THE LATE WEEKEND AND CENTERING OVER SOUTHERN NEVADA BY
MONDAY EVENING. THIS WILL LEAD TO AN INITIAL MOISTURE TAP ARRIVING
INTO THE WESTERN PROTONS OF THE CWA INTO SUNDAY, OFFERING SPOTTY
STORM AND SHOWER ACTIVITY FOCUSED OVER ARIZONA. AS THE TROUGH
CONTINUES TO BUILD THROUGH SUNDAY, TROPICAL MOISTURE FROM WHAT WILL
BE THE REMNANTS OF HURRICANE POLO BEGIN TO INTERACT WITH THAT POTION
OF THE JET STREAM AND PULL NORTHWARD. THE MAIN FOCUS OF THE PUSH OF
MOISTURE LOOKS TO BE WELL TO OUR EAST, HOWEVER THE LOW PRESSURE
CENTER ASSOCIATED WITH THE TROUGH WILL WRAP SOME OF THE MOISTURE
INTO SOUTHERN NEVADA. THIS WILL LEAD TO STRONG CHANCES FOR SHOWERS
AND STORMS ACROSS THE WESTERN HALF OF THE CWA, WITH THE BEST CHANCES
ALONG FOCUSED OVER MOHAVE CO. THE SHEER-RICH ENVIRONMENT ALONG WITH
THE COOLER TEMPERATURES AROUND THE LOW PRESSURE CENTER COULD TO
BETTER CHANCES FOR SEVERE STORMS MONDAY AFTERNOON AND INTO THAT
NIGHT. RAIN CHANCES LOOK TO EXIT TUESDAY AFTERNOON WITH QUIETER
WEATHER EXPECTED FOR THE REST OF THE FORECAST PERIOD.
