Near term
Today through tonight... Strong cold front will continue pushing
southward today while north-northeast flow will bring cloudy
conditions to much of northeast fl. Scattered showers with isolated
embedded thunderstorms (early today) are expected over the southeast
zones. Much cooler with highs in the 70s... Roughly 15-20 degrees
cooler than Monday. Most precip will be moving south of the area
this afternoon. Still can't rule out isolated to scattered showers
for the northeast fl coastal areas due to low level convergence and
moisture flux off atlantic. For tonight... Skies become mostly clear
north zones and cooler drier airmass will filter south across
inland areas of SE ga and the suwannee river valley. On the
northeast fl coast... A threat of isolated to scattered showers will
remain through night... With best chances south of st augustine at
around 50-60 percent. Temps will actually be a little below normal
with lows around 50 degrees in alma and waycross. Otherwise... Lows
in the mid to upper 50s inland and near 70 along the coast in the
onshore flow.

Short term Wednesday through Friday ...

high pressure will continue to the north this period, with enhanced
onshore flow. A series of troughs are expected to develop in this
onshore flow pattern and move west into the forecast area this
period. As these troughs develop and move west gradient winds will
increase and showers will move ashore.

Temperatures will trend from near to slightly below normal to above
normal this period.

Long term Friday night through Tuesday ...

the center of the surface high will drift from the north to the
northeast of the region this period. With this pattern the flow will
shift from the northeast to east then southeast. The southeast flow
will lead to a warmer and more moist airmass with precipitation
chances increasing through the period. The long range models diverge
on timing of a cold front in the Monday into Tuesday time period.

The main difference in timing will affect the temperature trend late
in the period. At this point forecast will depict a cooler day for
Tuesday than Monday, due to the potential front and expected
precipitation.

Temperatures are expected to trend above normal for much of this
period, then near normal Tuesday.

Aviation
Ifr CIGS may continue at vqq through sunrise then lift to
MVFR. For remainder tafs, MVFR CIGS will persist for the better half
of today with CIGS slowly lifting by this afternoon and evening.

Brisk north northeast winds expected for coastal tafs with lower
winds inland around gnv and vqq. Some improvement expected by this
evening withVFR CIGS expected as some drier air filters in north-
northeast flow.

Marine Strong north-northeast winds expected through
Wednesday with SCA in place with gusts to gale force at times.

Winds seas will remain elevated through the remainder of the week
as moderate to strong high pressure remains north of the area.

Rip currents: high risk of rip currents due to strong
northeasterly winds and rough and building surf.

Coastal impacts Surf is expected to build to 5 to 7
feet and have raised high surf advisory with this forecast package.

Regarding water levels along the coast... Though we are only touching
action stage at a few sites at this time, the surge of winds and
continued onshore flow will enable some minor coastal flooding
potential by this evening. On the st johns river, currently seeing
minor flooding being reached at racy point and main street bridge
with the high tide. Given the moderate to strong northeast winds
these water levels will continue to be elevated and potentially
rise through 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.
