Satellite indicates some low clouds, patchy fog making its way through the Delta into the Valley early this morning. This trend should continue through day break but overall will remain locally to the Delta region. Some patchy low clouds may make it to Sac Exec and Stockton but should dissipate quickly after sunrise. Upper level ridging will remain in place for today keeping mainly clear skies and quiet conditions. Overall we will see similar highs to what we saw yesterday but they should be a few degrees warmer in the north.
Over the weekend a deep cold trough will dig out of Central Canada into the central US. This will flatten the ridge over the west and we will move into to a short period of zonal flow. This will bring some high clouds to region later in the day Saturday into Sunday. Upper level ridging builds back in on Sunday but high clouds will continue to pass over the area.
Overnight lows will be near average for the period with the exception of the thermal belts where they will run 10 to 15 above average. 10 to 20 degree above average highs will continue into the weekend and early next week.
Extended Discussion (Tuesday through Friday)
Not much change in the forecast this morning as ensemble and model guidance hold the Eastern Pacific Ridge over us. This means warm and dry conditions are forecast to continue for much of the period; however, there is still a small chance of a weak trough sliding over northern California next weekend. Precip chances look to be quite light if this were to pan out and likely stay north of Hwy 36. Confidence is low in this event happening, but it`s something we`ll be keeping our eyes on.
