This stall lead to prolific rains falling in Pennsylvania between the 21st and 23rd, with Philadelphia getting the lion's share of rain on the 22nd, while Northern and Central Pennsylvania picked up the brunt of the storm on the 22nd and 23rd.

One of the byproducts of the weather pattern that Agnes and the upper level low produced in Pennsylvania was record cold high temperatures. Philadelphia recorded its latest sub 60 degree high on record on June 23rd -- 58 degrees -- the coldest any high temperature had been that late in the year. Other very cool highs for June 23rd included 54 in Scranton, 57 in Allentown, 53 in Palmerton (near Jim Thorpe), and a brrrr-riffic 50 in Donegal in Western Pennsylvania.
Between the rain and cold, it was a miserable pattern for the latter portions of June. The rain, compounded on top of prior rains, created an even bigger problem that ultimately cost nearly two billion dollars in damage. Our next post will talk about Agnes' flooding.
