(CBS13/NWS) A few late-day showers will be possible over the northern Sierra this afternoon, otherwise dry and warm weather through the weekend. Temperatures will warm to the upper 80s to low 90s by
Sunday for Valley communities.

Omega blocking pattern setting up over the Eastern Pacific and
West Coast will keep dry and progressively warmer conditions over
NorCal heading into the weekend. The only exception will be isolated showers over the Sierra this afternoon, as this area is on the western edge of the trough over the Great Basin undercutting the ridge. Best shower chances will be from the upper foothills to about 5000 feet. Valley high temperatures will generally be in the low 80`s today, mid 80`s Saturday, and near 90 Sunday. Highs will be in the upper 70`s to low 80`s foothills and lower mountains heading into the weekend. Area waterways will remain much colder than the air temperatures due to snowmelt, please
use caution near waterways.

Short-range ensemble and clusters are in good agreement with blocking pattern breaking down Monday, as strong reinforcing trough drops south over the Rockies. This will lead to slight cooling with Valley high temperatures falling back into the low 80`s.

Models continue to differ with depth and track of upper lows
Tuesday into Thursday. Available moisture is limited and NBM
trending drier on Tuesday. Models similar in generating some potential precip over the Sierra Nevada Wednesday. The forecast leans toward drier upper ridging towards the latter part of next week. Locally gusty north to east wind possible at times Tuesday into Thursday. High temperatures remain about 10 to 15 degrees above normal through the extended forecast period.
