I didnʼt note anything up here on the North Shore at that time, 
beyond some weak 27 MHz (the CB band, particularly 
27.025—Ch.6—the prime “skipland” channel) activity.
There are a couple of “skip maps” out there that show whats going on:


as well as a whole dx map site:

As a specific, pure causation, no.
However, its prime times are late morning–early afternoon, then 
again around supper time.
One of the believed causes of E‑skip is thunderstorm activity 
(somewhere in range of the skip path, not necessarily at the end 
points), which usually settles down at sunset.
Also, a specific subtype of E‑skip is meteor scatter, which is 
usually—but not always—“ping”y (particularly noticeable on 27 MHz).
