What the Big Storm Left Behind.....

Meteorologist Jim Woodmencey

The big storm that brought rain and snow this week to the Northwest and the Northern Rockies will be moving across the central Rockies and the northern Plains the next 24-hours or so.

What it left behind was fairly impressive, with record September snowfall at Crater Lake National Park in Oregon of 8 inches in 24-hours Tuesday into Wednesday, above about the 6,000-ft. elevation.

At the Jackson Hole Mountain Resort there was also about 8 inches of snow reported up there at about the 9500-ft. elevation, which accumulated from just before midnight Tuesday through Thursday morning Sept. 26th. Togwotee Pass had about 10 inches at the same elevation. And the higher elevations in the Wind River Range had more than that, and appear to have the deepest snow accumulations from this storm.

Rain in the Town of Jackson was also significant, at the automated rain gauge in town 1.26 inches of rain fell in less than 24-hours. Significant because the average rainfall for the month is 1.29 inches.
