.PREV DISCUSSION... /issued 307 PM CDT Tue Mar 31 2020/

SYNOPSIS...
Nice weather is expected for the next couple of days as a high
pressure system brings a dry continental air mass to the region.
This will allow for cool nights, mild days, and no rain. Flow off
the Gulf will resume by the end of the week with a return to warm
and humid conditions, along with chances for rain.

DISCUSSION...
A cold front has swept through the forecast area with a drier
continental air mass now settling in. This air mass will persist
for the next few days bringing with it cooler more seasonable
conditions, especially at night, along with mild days. Rain
chances will be near zero for through the early part of Thursday.

The high pressure system that will bring the more seasonable
conditions will move east to the Mid-Atlantic region by Thursday.
Therefore, southerly winds will return allowing the Gulf to open
up and bring back warm and humid conditions.

There are still some fluctuations in the Guidance over the
weekend, but at this time Saturday looks like the day that will
have the better rain chances, with Sunday possibly being a bit
drier.

An unsettled pattern with very warm and humid conditions look to
be in store for early next week.

Rua

MARINE...
Elevated northerly winds will continue over the coastal waters
tonight into early Wednesday as a cool high pressure system builds
into the area. Wind speeds will exceed 20 knots at times for the
coastal waters east of Intracoastal City so a small craft advisory
will be in effect for that area. Winds will gradually decrease
during the day on Wednesday as the surface ridge settles over the
coastal waters. The high pressure will then move off to the east
on Thursday with onshore flow returning that will then persist
into the weekend.
