Heavy rainfall is occurring again in Fairbanks this morning - the fourth time in less than three weeks, and this time accompanied by thunder in the early morning hours. As of 8:11am AKDT, 0.84 inches of rain had fallen.
At Fairbanks airport between 1998 (when the change to ASOS occurred) and 2013, an observation of "heavy rain" was reported on only 27 days. Seven of these 16 years did not see any reports of heavy rain, while the record in this period was 8 heavy rain days in 2008. We have now seen 4 events in the past few weeks (June 19, June 26, June 30, and now today).
The culprit for today is a near-stationary east-west band of rainfall with embedded convection. Let's hope it doesn't remain in place too long, or it will cause renewed flooding concerns.
