DISCUSSION
UPPER LEVEL RIDGING WILL REMAIN OVER THE SOUTHERN UNITED STATES
INTO THE EARLY WEEK. THE UPPER HIGH SHOULD HELP SUPPRESS THE
DEVELOPMENT OF SHOWERS TODAY. EXPECT MORE VERY WARM TO HOT
CONDITIONS, WITH HIGHS RISING INTO THE MID/UPPER 90S, AND
CORRESPONDING HEAT INDEX FROM 100 TO 109 DEGREES. MINIMUM
AFTERNOON RELATIVE HUMIDITY VALUES SHOULD BE REDUCED INTO THE
LOWER 40S PERCENT RANGE. GOOD SMOKE DISPERSION RATES ARE FORECAST
TODAY.
A RETURN OF SOMEWHAT DEEPER MOISTURE, ALONG WITH AN APPROACHING
COLD FRONT WILL BRING MEDIUM CHANCES OF SHOWERS AND THUNDERSTORMS
MONDAY AFTERNOON. SOME OF THE STORMS COULD BECOME SEVERE, WITH
STRONG TO DAMAGING OUTFLOW WIND GUSTS THE MAIN THREAT.
FOG POTENTIAL OVER THE NEXT FEW DAYS: PATCHY FOG COULD FORM IN
AND NEAR SHELTERED VALLEY LOCATIONS IN THE LATE NIGHT AND EARLY
MORNING.
POTENTIAL FOR RED FLAG CONDITIONS: NOT FORECAST AT THIS TIME.
