area forecast discussion
national weather service jacksonville fl
228 pm edt Wed mar 22 2017

Near term /through tonight/
Mostly clear skies and warm temps this afternoon as cold
front moves across the area. Behind front, increasing
northeast surface flow will set up tonight as strong high
pressure builds well north of the area. Satellite imagery is
showing development of low cloudiness well offshore. Model
guidance suggests this cloudiness will expand southwestward
over the coastal counties this evening... And further inland
later tonight. May also be some coastal east of i-95 corridor
in NE fl. Consensus guidance shows little change in low temp
forecast for tonight... With mid 50s SE ga... Upr 50s- lwr 60s ne
fl. NE winds are likely to stay up in the 10-15 mph range well
inland... 15-20 mph range near coast.

Short term /Thursday thru Friday night/
Strong high pressure will build over mid-atlantic coast thur
and move just offshore fri... While strong upper ridge builds
over the southeastern u.S. Model guidance suggests coastal
showers may affect areas S of jax Thursday through Friday in
enhanced onshore flow pattern. Cooler high temps Thursday...

65-70 SE ga... Upr 60s-lwr 70s NE fl... Perhaps mid 70s marion co.

Slightly warmer Friday... With lwr-mid 70s across the area...

possibly upr 70s far western part of forecast area.

Long term /Saturday thru Wednesday/
Strong central u.S. Upper system Sat will lift NE and
pass well N of our region sun. Cold front falls approaching
the area from the west late Sat falls apart on sun... While
high pressure remains in control offshore of the mid-atlantic
region. Model guidance suggests low probs for widely scattered
showers... Possibly isolated t-storm Sunday and mon. Continued
low pop for some areas tue... But greater uncertainty tue-wed...

so primarily followed consensus guidance.

Above normal temps this period with high temps rising into the
lwr-mid 80s well inland... Upr 70s coast with onshore flow...

and low temps in upr 50s well inland... Lwr 60s coast.

Aviation Vfr conditions with NW winds becoming more northerly
late today... May be gusty at times particularly coastal TAF sites.

Model guidance suggests potential for MVFR CIGS to develop over
coastal waters and spread inland over NE fl... Show this after 06z
in tafs. Also included vcsh in tafs though best chance appears to
be kcrg/ksgj.

Marine Maintaining SCA for waters into Friday for winds and/or
seas reaching criteria. Strong high pressure north of the waters
will increase NE to E flow late this afternoon into Friday. Some
decrease in winds with decreasing pressure gradient during the
weekend... But seas will be slow to decrease due to easterly swell.

Rip currents Moderate risk this afternoon... High risk Thursday
with greater onshore component to the surface flow.

Fire weather With onshore flow pattern developing and existing thru
weekend... Min rh values should stay above critical values. Breezy
conditions expected through Thursday... With lighter winds thereafter.

Elevated dispersion values are forecast for the next few days.

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.
