.DISCUSSION...

.SYNOPSIS...
Broad zonal flow across NorCal for the next few days, leading to
seasonable temperatures and breezy onshore flow. Ensembles
continue to depict weak troughing arriving this weekend, leading
to slightly lower heights and cooler highs over the weekend. Early
next week, troughing moves into the Four Corners region and on
Tuesday areas of breezy north winds may develop, especially in the
northern/central Sacramento Valley with continued onshore flow in
the Delta and vicinity. Warming high temperatures by Tuesday will
also introduce areas of Moderate HeatRisk in the northern
Sacramento Valley, followed by widespread Moderate HeatRisk for
the rest of the area on Wednesday. &&
