.DISCUSSION...
WARMER AND DRYER TODAY. THERE IS STILL A CHANCE OF AN EVENING SHOWER
AND THUNDERSTORM ASSOCIATED WITH A SHORT WAVE MOVING NORTHEAST FROM
IDAHO AND UTAH. THERE IS STILL ENOUGH MOISTURE AROUND FOR THE STORMS
TO BE WET. RH RECOVERY WILL BE GOOD OVERNIGHT.

SHOWERS AND THUNDERSTORMS WILL REMAIN IN THE FORECAST FOR THE WORK
WEEK AS THE AREA STAYS ALONG THE PERIPHERY OF A HIGH OVER THE
SOUTHERN UNITED STATES. DISTURBANCES WILL RIPPLE ALONG THE PERIPHERY
FROM TIME TO TIME BEFORE THE HIGH BUILDS NORTH AND WEST OVER THE
WEEKEND. TEMPERATURES WILL BE ON A SLIGHT UPWARD TREND AND RHS WILL
BE ON A SLIGHT DOWNWARD TREND. RHS COULD DROP INTO THE SINGLE DIGITS
THIS WEEKEND. WINDS WILL BE PRIMARILY DRIVEN BY DRAINAGE WINDS AND
NEARBY SHOWER OR THUNDERSTORM ACTIVITY.
