NATIONAL WEATHER SERVICE PITTSBURGH PA
225 AM EDT SUN AUG 9 2026
DISCUSSION
A BREAK FROM THE ACTIVE WEATHER PATTERN IS EXPECTED TODAY DURING
THE DAYTIME AND EVENING HOURS AS HIGH PRESSURE PAYS A BRIEF VISIT.
HOWEVER, DAILY SHOWER AND THUNDERSTORM CHANCES RETURN MONDAY AND
CONTINUE THROUGH MUCH OF THE WEEK, THANKS TO A SERIES OF PASSING
DISTURBANCES AND A SLOW-MOVING FRONT. GIVEN PAST AND EXPECTED
RAINFALL, AND CONTINUED MINIMUM RH LEVELS ABOVE 50 PERCENT, FIRE
WEATHER CONCERNS ARE NIL.
