311 pm edt Sat mar 25 2017

Near term an upper level low and short wave trough continues
over the mississippi river valley moving slowly east with the
attendant cold frontal system over mississippi and louisiana. The
high pressure system over the western atlantic ridges west into the
southeastern coast with a surface east-southeasterly flow.

The upper level low and front will drift east through tonight and
approach the region Sunday afternoon and evening. Right now looks
like the upper pattern and instability will favor showers and a few
thunderstorms but doesn't look like a severe event at this time.

Precipitation totals on Sunday into Sunday night look to be between
1/4 and 1/2 inches. This is not going to be a drought buster nor is
it likely to reduce current the above normal dryness.

Short term /thru Monday night/
Any remaining convection... Which appears will be along the i-75
corridor... Will come to an end Sunday evening after the loss of
heating. Mid level impulses begin to dig into the broad ridging over
the area and in combination with afternoon heating and seabreezes
will help produce isolated storms mainly across inland areas. Any
storms that manage to get going will fade in the evening after loss
of heating. High temps reach the lower/mid 80s inland and mid/upper
70s along the coast. Lows in the upper 50s inland to lower 60s coast.

Long term /Tuesday-Saturday/
Fairly progressive pattern expected with a mid/upper ridge moving
out of the area early Tuesday followed by another one over the area
Thursday. A weak front washes out over the area wed-thur... In
between ridges... Bringing a low end chance of showers mainly to
southeast ga but continued dry elsewhere. A more potent short wave
trough will approach Friday bringing a better chance of showers and
possible storms. Differences exist between the GFS and ECMWF with
the GFS digging short wave energy further south than the ECMWF and
therefore much wetter. For now... Have taken a blend of models and
have 40-50% pops with isolated thunder. Temps will run much above
normal most of the week with MAX temps well into the 80s across
inland areas.

Aviation The cumulus cloud streets and marine stratocumulus
layers will remain between 4 and 6 thousand feet today with the
inland cumulus dissipating quickly after sunset. Winds this
afternoon and early evening will be between 120 and 150 degrees at
10 to 12 knots gusting to 16 knots. The lower layers will decouple
tonight allowing a light and variable flow and enough mixing for
light fog/mist especially in the inland stations such as kvqq and
kgnv.

Marine With the ridge holding along the eastern seaboard we
will maintain a east to southeast flow with small craft exercise
caution conditions over the offshore portion of the coastal waters
into tonight. Otherwise winds shift to southwesterly ahead of the
next front and northerly behind it but conditions remain below small
craft advisories. Will have to watch the development of the large
low northeast of the bahamas to see if a swell moves into the area
later next week.

Rip currents: a moderate risk of rip currents on Sunday with a
continued east-southeasterly flow.

Fire wx A frontal boundary that will be stalling well to the
northwest of our region Sunday which will produce scattered mainly
afternoon and early evening showers and storms mainly across inland
areas. Afternoon sea breezes will develop on Sunday and Monday
afternoons at the atlantic and gulf coasts and will push inland
during the mid to late afternoon hours. Minimum relative humidity
values will remain well above critical thresholds area-wide through
Monday.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
