.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
A warm front that was located near the coast has surged north and is
well inland now as a cold front approaches from the west. Scattered
showers and thunderstorms may develop across the coastal waters
early this morning through the afternoon. Shear is quite light and
instability just enough for thunder but not severe. A tightening
pressure gradient has beginning to increase winds west of the MS
River per recent marine obs. With those speeds exceeding 20 knots,
have recently initiated a Small Craft Advisory. This matches up
perfectly with model boundary layer wind forecast. That forecast
also shows those winds dropping off around sunrise as the tight
pressure gradient will be a short wind mostly due to the proximity
of the surface low to the local area and the progressive nature of
this system. The actual front will finally move through the coastal
waters Wednesday morning as deepening comma low rolls into the Great
Lakes Region. The combination of cold air advection over the
relatively warm waters, and the pressure gradient between the high
and low will cause winds to strengthen into the 20-25kt range and
Small Craft Advisories will likely be needed Wednesday afternoon
through at least midday Thursday. As the high settles into the area
later in the week, winds will ease and turn back to the southeast as
the high shifts east of the area by Saturday.
