Synopsis
Issued at 256 pm edt Sat aug 24 2019
- continued mild and dry through Sunday night
- rain chances gradually increase Monday, with the best chance
Monday night
- a couple of rain chances Wednesday and Thursday night with cool
conditions holding on

Discussion (this evening through next Saturday)
issued at 256 pm edt Sat aug 24 2019
not much to focus on until Monday with high pressure at the sfc and
aloft holding on over the area. Dry feed of air from the E NE will
continue to allow for low humidity values and mild temperatures
through Sunday night.

We are still expecting rain chances to slowly increase on Monday,
and peaking Monday night and early Tuesday. The wave that will be
driven in toward the NE by the larger scale trough to our west will
bring the rain chances during the daylight hours on Monday. There
has been a slight trend for this wave to go a little further east,
and focusing on the SE half of the area. There looks to be a break
in the activity Monday evening, before the main front moves through
Monday night.

There looks to be around 1,000 j kg of mu CAPE ahead of the front
Monday night. This should be plenty for storms to remain possible
through the night. Fortunately, they will come through during the
night, and instability looks to be elevated in nature. This should
limit the severe threat quite a bit. A bigger threat will be heavy
downpours with precipitable water values approaching 2 inches.

Widespread flooding is not expected with this system relatively
progressive in nature. There will be some lingering showers Tuesday
morning, before the front clears the area, and clouds and rain clear
out toward afternoon.

The next noteworthy system will wait until Thursday night to move
through. However, we will be under the influence of general
troughing until then. The models have trended a little south with
clouds and instability showers for Wed into thu. So we have small
chances in for that period. The front has better consensus amongst
the models that bring rain through mostly on Thursday night.

We should clear out once again after the Thursday night front, but
will be watching how far south the front goes. There are indications
that a wave will ride along the front, and a band of rain will move
through just north of the front.

vfr expected through the period. Scattered to broken clouds aoa
12k feet through 06z mon.

Marine
Issued at 256 pm edt Sat aug 24 2019
we continue to expect that winds will be on the increase on Sunday
as the pressure gradient tightens up a bit as high pressure moves
east. Waves will build a little, but should not build too much with
an offshore component to the wind.

Winds will then remain up for the most part through the first part
of Tuesday with the passage of the system Monday night. It looks
likely that at least a small craft advisory will be needed for that
time frame. Winds should then slacken a bit for later Tuesday,
before they come back up by Wednesday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
