.SYNOPSIS...
A WEAK WEATHER SYSTEM WILL MOVE THROUGH THE REGION WEDNESDAY. AN
EXTENDED PERIOD OF DRY WEATHER THEN COMMENCES CONTINUING INTO
NEXT WEEK.

&&

.DISCUSSION...
Another weak system will be moving into the interior Wednesday and
Wednesday night. This system will be slightly stronger but overall
precipitation amounts will still be light. It will move through
the region Wednesday through Wednesday evening with some lingering
mountain showers over the western slopes into early Thursday.
Precipitation amounts will generally be around a tenth of an inch
or less in the valley with amounts for the foothills and
mountains generally between .20 to .40 of an inch. Snow levels
will start out higher with this system but lower Wednesday night.
The one exception is that in Shasta County showers in the morning
may fall as low as 1500 feet before rising to 2000 to 2500 ft for
the afternoon. 2 to 5 inches are expected with this system with
the higher amounts from Western Plumas County northward.

Thursday will be dry as high pressure builds over the region.
Northerly winds may become locally breezy on Thursday for the
valley and easterly winds in the mountains Thursday night might
become locally windy. The winds will be lighter for Friday as a
system either moves through to the north or brings some light
precipitation Friday afternoon and evening to parts of the
interior. The GFS is deeper with this system so still some
uncertainty.

&&
.EXTENDED DISCUSSION (Saturday THROUGH Tuesday)

Large upper level ridge will dominate into next week. A weak
system attempts to enter NorCal on Saturday but will only have
limited moisture to work with. A few showers might impact Shasta
County, but that`s about it. Otherwise dry, unseasonably warm
weather expected with temperatures some 10 to 15 degrees above
normal by Monday.

areas of MVFR after 12z and precipitation after 18z. Generally
light winds expected. EK
