337 AM CDT Sat Apr 27 2024

.SYNOPSIS...
A tight pressure gradient between a series of lows over the
Southern Plains and a surface high off the east coast will allow
for a prolonged period of strong and gusty southerly/onshore
winds. Sustained winds are likely to be near or above 20 knots
through the weekend with gusts over 30 knots. This, along with
building seas to as high as 10 feet offshore, will bring about a
long duration Small Craft Advisory conditions through the weekend.
Showers and thunderstorms return over coastal waters late Sunday
with elevated rain chances continuing into late Tuesday. The
onshore winds will decrease early next week as the high weakens
off the east coast and no deep surface lows are expected to form
over the Southern Plains.
