We had a strong downpour move threw the area around 10:30pm; the paper towel sample swipe read a surprisingly low 0.077 mR/hr which is only 7 times greater than normal background radiation. This is the first reading below 20x greater than background since August.
A quick check of the Jetstream maps quickly showed the reason for the lower reading. Eventhough the Jetstream is currently strongly present overhead, it appears to be the southern Jetstream. The more southern jetstream explains today's warmer temperatures and the reduced presence of Fukushima fallout.
