VALUES ACROSS THE AREA WILL LEAD TO ABOUT A 2-4 DEGREE DROP IN HIGHS
ON TUESDAY WITH ANOTHER 2-4 DEGREES ON WEDNESDAY. WINDS ACROSS THE
REGION WILL INCREASE WITH BREEZY TO LOCALLY WINDY CONDITIONS
EXPECTED AREA WIDE. RIGHT NOW IT DOES NOT LOOK LIKE THE STRONGER
WINDS WILL BE WIDESPREAD ENOUGH TO WARRANT WIND ADVISORIES. THE NAM
AND TO A LOWER EXTENT THE GFS ARE SHOWING A WEAK DISTURBANCE MOVING
THROUGH NORTHERN LINCOLN COUNTY TUESDAY AFTERNOON. THERE LOOKS TO BE
ENOUGH MOISTURE BETWEEN 700-500MB COMBINED WITH LI VALUES BELOW 0 TO
LEAD TO AN ISOLATED THUNDERSTORM DURING THE AFTERNOON. NOT EXPECTING
MUCH...BUT A LIGHTNING STRIKE OR TWO IS NOT OUT OF THE QUESTION.

FOR THE LAS VEGAS VALLEY WHICH IS GENERALLY WHAT THE LOW TEMPERATURE
WAS THIS MORNING. THE SYSTEM WILL HAVE LIMITED MOISTURE ASSOCIATED
WITH IT...HOWEVER WITH THE COLD POOL ALOFT...UNSTABLE CONDITIONS
WILL LIKELY FORM ISOLATED SHOWERS/THUNDERSTORMS OVER MAINLY THE
NORTHERN/EASTERN MOUNTAINS. AS THE SYSTEM SHIFTS NORTHEAST
SUNDAY/MONDAY...INCREASING HEIGHTS/THICKNESS TO BRING WARMER
TEMPERATURES/DRYING/AND LESS WIND TO THE CWA.
