...EVENT SUMMARY...
The first Fall weather system brought plenty of rain to the area and
some mountain snow as well over the past two days. This weather
system brought impressive rain to central portions of the area
thanks to nature of how it passed through the region. On Sunday it
began sliding down from the north and then Monday into Monday night
it pivoted to the south and east. This pivot allowed for persistent
moderate rain from Lander to Thermopolis Monday through Monday
night. Rain persisted at Casper through Tuesday morning and ended
early in the afternoon. Below you will find 48 hour rainfall totals
from Sunday morning through Tuesday morning.
