NATIONAL WEATHER SERVICE MELBOURNE FL
300 PM EDT THU MAY 21 2026
DISCUSSION
THE PERSISTENT WEATHER PATTERN WILL CONTINUE THROUGH THE WEEKEND AND
INTO EARLY NEXT WEEK WITH LITTLE TO NO CHANGE. HIGH PRESSURE
PREVAILS, MAINTAINING ONSHORE FLOW EACH DAY. EAST-SOUTHEAST WINDS 10-
15 MPH GUSTING TO AROUND 20-25 MPH IN THE AFTERNOON, ESPECIALLY
BEHIND THE INLAND-MOVING SEA BREEZE. MOISTURE GRADUALLY INCREASES
THIS WEEKEND INTO EARLY NEXT WEEK, SO THERE ARE NO MIN RH CONCERNS.
RAIN CHANCES REMAIN LOW OVERALL, WITH ISOLATED SHOWERS ALONG THE
COAST OVERNIGHT AND INTO THE MORNING HOURS EACH DAY, SHIFTING INLAND
BECOMING SCATTERED IN COVERAGE DURING THE AFTERNOONS, AND TOWARDS
THE WEST FLORIDA COAST IN THE EVENINGS. A SLIGHT INCREASE IN RAIN
AND LIGHTNING STORM CHANCES ARE FORECAST THIS WEEKEND (30-50%)
ESPECIALLY INLAND, BUT NOT EVERYWHERE WILL SEE MEASURABLE RAINFALL
OVER THE NEXT 7 DAYS. GENERALLY GOOD TO VERY GOOD DISPERSION IS
FORECAST LATE WEEK INTO THE WEEKEND.
FOG POTENTIAL...WIDESPREAD FOG IS NOT FORECAST. LOCALIZED VISIBILITY
REDUCTIONS DUE TO SMOKE FROM NEW OR EXISTING FIRES WILL BE POSSIBLE
EVEN IF FOG IS NOT FORECAST.
