Synopsis..A light onshore flow is expected through early Monday as a ridge of high pressure to the north of the marine area early this evening shifts east through Monday. Westerly winds increase and seas build on Monday in response to a cold front approaching from the northwest.

06z issuance...VFR conditions forecast next 24hrs. Surface high
pressure will be east of the area, resulting in light variable to
calm wind overnight, becoming light from the southeast during the
day Sunday. Passing clouds will be high based cirrus. 10

discussion... See updated information for land areas below.

Update... 02z surface observations across the forecast area
showing temperatures trending about 2 to 6 degrees below forecast
values as a quick drop has occurred this evening due to the very
dry airmass that mixed out this afternoon. Sent an update to the
public products to adjust for current observations, the
anticipated overnight temperature trend, and updated overnight
lows, which are now expected to be about 2 to 5 degrees below the
previous forecast values. Look for lows to dip into the low to mid
40s inland areas, mid to upper 40s along the coastal sections,
and lower 50s along the beaches. Remaining forecast elements
trending as forecast. 22

near term now through Sunday ... Surface high pressure centered
northeast of the area today will shift east off the southeast
atlantic coast and be more east of the area on Sunday. This will
allow the surface ridge axis over our area to gradually change from
northeast to east on Sunday. This will support light and variable
surface winds across most of the area tonight, expect for right
along the coast where light east to southeast winds (around 5 mph)
should be expected. On Sunday, as the ridge axis become more east-
west oriented, a continued light but more southeast to south flow is
expected to develop over the entire area. Dry conditions will be
maintained, although occasional thin high clouds will continue as a
weak mid upper level impulse seen in water vapor imagery moving east
out of tx and into la this afternoon moves east across the our area
tonight and early Sunday. There may be a few isolated showers out
over the gulf to the south of the region on Sunday afternoon, but
will not include any slight pop in forecast for now. A little warmer
tonight than last night, with lows ranging from the mid and upper
40s over interior zones to the lower 50s closer to the coast.

Another nice mild day on Sunday, with highs in the mid to upper 70s
over the interior but in the lower 70s along the coast where the
influence of the light onshore breeze will be more evident. 12 ds
short term Sunday night through Tuesday night ... A shortwave
trof (located at the base of a longwave trof over the interior
eastern states) advances from the eastern plains into the
southeast states through Monday night, then moves into the
western atlantic Tuesday night. An associated surface low moves
from near the mississippi ohio river confluence Sunday night to
the carolinas Monday night, meanwhile bringing a cold front
through the forecast area late Monday afternoon into Monday
evening. The surface low continues into the western atlantic
during the remainder of the period while a large surface ridge
meanwhile builds from the plains into the eastern states. Mostly
dry conditions Sunday night will be followed by pops increasing
to likely over interior areas by Monday with lesser pops
elsewhere as the front advances into the area. Slight chance to
chance pops follow for much of the area Monday evening as the
front finishes moving through the area, then dry conditions return
later Monday night and continue through Tuesday night. Mlcape
values increase possibly as high as 500-1000 j kg Monday afternoon
before dropping off quickly by early evening. Shear values will
generally be low, but it was also noted that wet bulb zero values
around 10 kft will be present. This environment may support some
strong storms and will continue to monitor. Another day with
temperatures several degrees above normal is expected for Monday
with highs in the mid to upper 70s, then Tuesday will be cooler
with mid to upper 60s for highs. Sunday night will be mild and
mainly in the lower to mid 50s. Monday night and Tuesday night
trend progressively cooler with lows Tuesday night ranging from
the lower 40s inland to the mid 40s closer to the coast. 29
long term Wednesday through Saturday ... An upper ridge shifts
from the central states to across the eastern states through
Thursday night then moves off into the western atlantic later in
the period. An upper trof meanwhile advances into the western
states through Thursday, after which there is considerable
uncertainty whether the upper trof moves into the interior eastern
states by Saturday or instead continues to linger over the
western states. There is fair agreement on a surface low
developing to the lee of the rockies over the central plains by
Thursday, then uncertainty follows for how quickly the surface low
ejects off to the northeast across or near the great lakes
region. For the forecast area, a light return flow develops by
Thursday and continues through the remainder of the period.

Depending on how the pattern evolves, it is possible that the
system will bring a weakening and decelerating cold front across
the lower mississippi river valley to near the forecast area on
Saturday. Have opted to have dry conditions continue through
Friday, then chance pops return to most of the area for Saturday
as either the front nears the area or at least modest isentropic
lift will be present. 29
marine... A light onshore flow is expected tonight through early
Monday as a ridge of high pressure to the north of the marine area
early this evening shifts east through Monday. Westerly winds
increase and seas build (especially over the gulf marine zones) on
Monday in response to a cold front approaching from the northwest.

The cold front is expected to move across the marine area Monday
night into early Tuesday, bringing a moderate to occasionally strong
offshore flow through early Wednesday. Exercise caution levels are
likely and small craft advisory could be required for the middle
part of the week. A lighter more east to southeast flow is then
expected late in the week, except well offshore where winds and seas
will remain up somewhat. 12 ds

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.
