.SYNOPSIS...
Light onshore flow this afternoon will increase somewhat overnight
as the pressure gradient tightens between an Eastward departing
surface high and an area of low pressure moving across the
southern plains. Onshore winds will strengthen further Monday and
Tuesday as another low pressure forms and deepens over the
Plains. Precipitation chances remain negligible until late in the
week.
