.SYNOPSIS...
A coastal low is expected to move across the northwest Gulf
through Saturday allowing for a modest offshore flow. The surface
low will linger over the region keeping a light to occasionally
modest northerly flow in place through the weekend. Early next 
week, the surface low will wash out with high pressure at the 
surface ridging in from the east. This will allow a light to 
modest southerly flow to develop.
