242 pm edt Sun sep 24 2017

Short term (tonight-Sunday)
An amplified pattern aloft will continue across the country through
Monday. A large trough over the west will continue to slowly swing
eastward while ridging remains over the northeast. The persistent
low over the northern gulf coast will linger into Monday but weaken.

At the surface, hurricane maria is forecast to continue moving
northward to a position offshore the carolinas through Monday, while
high pressure remains to our north. The overall flow should be more
northerly and also a bit lighter on Monday due to a lessening
pressure gradient as maria moves northward, and this would allow a
stronger west coast sea breeze to develop in the afternoon. Having
said that, some drier air moving in on those more northerly winds
along with subsidence over the region will keep rainfall coverage
even lower on Monday. Temperatures will top out in the upper 80s to
lower 90s.

Long term (Monday night-Sunday)
Deep troughing extends from the dakotas south to western mexico.

Ridging extends over the florida peninsula and new england states.

This ridge is helping to steer hurricane maria and keep it off the
east coast of the u.S. On the surface, high pressure will remain in
control of the weather across the florida peninsula. In the western
atlantic, hurricane maria continues to make her way northward.

Models continue to take this storm to the north and maria is not
expected to pose a threat to the florida peninsula. With high
pressure over the region for the next several days, rain chances
will be on the low side (10-30%) pops with seasonal temps expected.

Aviation
Widely scattered showers and thunderstorms continue to move toward
the coast this afternoon and could cause brief restrictions at area
terminals through this evening. After 01z or so, expect most
activity to be offshore and soVFR is expected to return for the
rest of the period.

Marine
High pressure centered north of the region will support east to
northeast winds across the area through tonight. Winds will then
become more north to northwest on Monday and Tuesday as hurricane
maria continues to move away from the region. No headlines are
expected for the next few days.

Fire weather
No fire weather concerns for the next few days as relative humidity
levels will remain above critical levels. Some patchy and shallow
ground fog is possible, but no widespread or dense fog is expected.

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.
