SYNOPSIS...

Gorgeous week ahead with quiet weather and temps a few degrees above normal. 
Slight change in the weather going into this weekend with cooler temps and damp 
conditions. Chance of light beneficial rain Saturday morning for most.

SHORT TERM...(Today and Tomorrow)

Quitessential summer-like pattern setting up early this week in the wake of a soggy
weekend. Brilliant visible satellite picture this afternoon showing mostly clear skies
with a hint of cumulus over some of the higher terrain. Peaking out the window here at our
Monterey office, we can see some of the Cumulus to our north over the Santa Cruz Mtns. All
in all not too impressive, and they will stay that way thanks to buildling high pressure over
the northeast Pacific promoting compressional warming aloft and large scale subsidence.
More of the same tomorrow, perhaps even fewer clouds during the afternoon. The subsidence
of the high pressure aloft and onshore wind will aid in the development of a strong marine
layer, which will allow our typical stratus and fog conditions to flourish during the
overnight and morning hours.


LONG TERM...(Wednesday through Saturday)

The aforementioned fair weather conditions will prevail through much of this week. The
peak of temperatures will likely be Tuesday and Wednesday where highs will be in the
upper 70s to near 80 for most inland locations. Coastal areas holding on to the marine layer
influence will still be warm and clear, but more like the 60s to lower 70s. The pattern
changes by the weekend when a progressive open wave is progged to move into the PNW. This
will bring much cooler temperatures and light rain by Saturday and gusty conditions beginning
Friday afternoon through Sunday morning. Stay tuned for further updates on timing.
