DISCUSSION
THE FORECAST CALLS FOR SCATTERED SHOWERS AND THE
POTENTIAL FOR ISOLATED THUNDERSTORMS, WITH A 40% CHANCE OF
PRECIPITATION DURING THE PERIOD. WITH LIGHT EASTERLY WINDS AND
MODERATE HUMIDITY, FEEL-LIKE TEMPERATURES MAY REACH AROUND 90°F OR
SLIGHTLY HIGHER, ESPECIALLY FOR THOSE WORKING OUTDOORS OR
ENGAGING IN STRENUOUS ACTIVITIES. WHILE RAIN MAY OFFER SOME
RELIEF FROM THE HEAT, SLOW-MOVING SHOWERS COULD CREATE
CHALLENGING AND POTENTIALLY HAZARDOUS CONDITIONS DUE TO WET
