More Lightning

Yesterday was the seventh day in a row of very substantial lightning activity in interior Alaska, and it was the second most active day on record (2012-present) for the Lower Yukon region, with nearly 3500 strikes in that part of the western interior.  Only July 11, 2019 had more lightning strikes in a single day in the Lower Yukon zone; but this year's activity is far ahead of 2019 year-to-date:

Here's a preliminary look at the spatial distribution of lightning this month, with data through the 25th.

The historical normal for June tends to be much reduced to the west of Galena and McGrath, and also across the northern interior, so the westward and northward extent of heavy lightning activity is the most unusual aspect of this persistent lightning outbreak.

On the other hand, the lightning "hole" around Fort Yukon this month is pretty typical.
