NATIONAL WEATHER SERVICE PITTSBURGH PA
216 AM EDT SAT AUG 8 2026
DISCUSSION
SHOWERS AND THUNDERSTORMS WITH MAINLY A HEAVY RAIN THREAT ARE
EXPECTED THIS MORNING. AFTER A LATE MORNING AND AFTERNOON LULL,
MORE SCATTERED SHOWERS AND STORMS ARE FORECAST DURING THE LATE
EVENING AND EARLY OVERNIGHT PERIOD, WITH A SLIGHTLY BETTER
POTENTIAL FOR GUSTY WIND. AFTER A BREAK SUNDAY, DAILY SHOWER AND
THUNDERSTORM CHANCES RETURN MONDAY AND CONTINUE THROUGH MUCH OF
THE WEEK DUE TO A SERIES OF CROSSING DISTURBANCES. WITH THE RAIN
CHANCES AND CONTINUED ELEVATED HUMIDITY (MINIMUM RH REMAINING
ABOVE 45 PERCENT EVEN ON SUNDAY), FIRE WEATHER CONCERNS ARE
MINIMAL.
