.DISCUSSION...
A very early Summer like weather set up will keep a persistent
south- southeast flow of 10 to 15 knots in place through the middle
of next week. Seas will remain well below any hazardous limits at
1 to 3 feet through the period. The greatest concern and unknown is
any shower or thunderstorm impacts. A series of disturbances will
try to produce an area of storms over the Red River area and these
may move towards the coastal waters before they dissipate. If they
develop, these specific type of systems normally do not play well
with the models and they usually surge southeast faster and stronger
than expected. If they do, expect locally higher winds and seas
around these storms. Afterwards, winds may become light and variable
for 3- 6 hours before the synoptic south-southeast winds take back
over.
