(CBS13/NWS) Unseasonably cool weather continues today. Warming trend returns over the weekend, then it will be much warmer next week.


GOES-West visible imagery reveals some cumulus development over
portions of the Coastal Range, southern Cascades, and northern
Sierra this afternoon. Elsewhere, generally clear skies prevail overhead with temperatures running within a few degrees of what they were this time 24 hours ago. The Longwave trough axis is positioned over California today, which will provide another afternoon with below normal temperatures to the region, as well as locally breezy conditions. Forecast highs will peak in the middle 70s to near 80 deg F across the Central Valley, or about 8 to 13
deg F cooler than normal. Delta breeze will kick on again later this afternoon and overnight, and will bring locally gusty onshore winds in/around parts of Solano, Yolo, and San Joaquin counties.

The upper-level trough will quickly push inland over the next 24
hours. Temperatures will begin a gradual warming trend on Friday with the 80s becoming more widespread throughout Valley communities. Still, these highs are forecast to fall below normal. A weak frontal system will clip far northern California, and will bring a 15 to 30 percent chance of showers to northern portions of the forecast area. Shower potential will linger for Saturday and Sunday afternoons across far northern California. Over the course of this timeframe, can`t rule out some light measurable precipitation for the far northern Sacramento Valley.

Meanwhile, the upper-level ridge will gradually build and strengthen
over New Mexico and the Desert Southwest by Sunday. We’ll have to
keep a close eye on this ridge as odds are increasing that we`ll
quickly flip back to above normal temperatures in the extended

By early next week, northern California will find itself wedged
between an upper-level low off the British Columbia coast and an
an upper-level ridge over the Four Corners region. Temperatures on
Monday and Tuesday next week will start off within several degrees
of mid-June normal highs — upper 80s to low 90s in the
Sacramento and northern San Joaquin Valley. Cluster analysis of
the various ensemble suites provide increasing confidence that the
the ridge over the Desert Southwest will expand westward, resulting
in warming across the region with triple digits appearing in the
forecast around Wednesday. Additional warming is likely heading
into the end of next week, as well.
