The ALDN notched another 2000 or so lightning strikes for the day, taking the seasonal total to 114,000 - not far below the seasonal normal. What a turn-around in the past three weeks.
A much cooler air mass is now in place, with the temperature struggling to reach 60°F in Fairbanks today; it's an early-autumn feel. Given the date on the calendar and the seasonably cool forecast for the next week, there's little chance of adding significantly to the lightning total after this point; we might say that yesterday's spectacle marked the end of summer.
Here are a couple of simple radar animations of yesterday's event: the second picks up where the first one ends. An impressive system for any time of year, but quite remarkable for August 16th.
