.DISCUSSION...
The ridging pattern will move along and be replaced by an incoming
tropical low that is already bringing showers to central and
southern California. For Mono County, rainfall could start as
early as this afternoon, with chances increasing to 20-30% and
creeping northward to the south end of the Tahoe Basin. Tahoe
Basin chances nudge upward for Thursday, with the bulk of the
showers remaining south of I-80. Actually, the best chances will
largely be found south of US-50 as the low migrates out into the
Great Basin by late Thursday and early Friday.
We look to dry out a bit for Friday, but shower chances return
Saturday, and are found northward, along and north of I-80. This
will be the result of the tropical low spinning and meandering in
a cut-off fashion, which will allow for lingering showers through
Sunday.
On the heels of the tropical low, a new frontal boundary will
approach from the west, drawing in more moisture for early week.
Widespread shower activity has shaped into a forecast with more
confidence the showers to increase and linger into the middle of
next week. HRICH
