Synopsis
High pressure and unseasonably hot conditions will dominate
into late next week.

Near term until 6 am this morning
Could see a brief sprinkle near the santee river, but nothing
measurable expected. Otherwise, warm and humid with lows lower-
mid 70s inland to around 80 at the beaches.

Short term 6 am this morning through Tuesday
The so-called "heat dome" will remain in place across the southeast
early this upcoming week, with both h5 heights and h85 temps about
as high as they have been on record for may in this part of the
country. With the jet stream displaced far to the north, a strong
deep layered ridge will remain to the south, resulting in
considerable sinking air. The sinking air is compressed, and as this
occurs it warms the air further. Combined this with the lack of
rainfall, and the area generally in a d1 or "moderate drought"
conditions will be near or at record levels the next few days.

There are hints that maybe a couple of stray showers could form
along the sea breeze that reaches near and inland from i-95 Sunday,
probably not much further inland than us-17 Monday, and again inland
from i-95 Tuesday. Plus there is a pronounced lee side trough not
far away. However, with so much subsidence in place, warm mid levels
and the lack of moisture outside of the h85-h7 layer, we have no
mentionable pop.

With deep offshore trajectories and the resulting downslope flow, we
stayed close to the pure low level thickness forecast scheme. This
will support MAX temps hitting the century mark (100f) all three
afternoon across a large portion of the area. There will be some
minor relief at the beaches due to the developing sea breeze, as
temps reach "only" the upper 80s to lower 90s.

Dew points will mix out each afternoon down into the lower and
middle 60s, but will pool back into the lower or lower to middle 70s
along the coastal corridor as the sea breeze moves inland. This will
put conditions very close to our criteria of issuing the pre-july
1st heat advisory as heat indices approach 105f over the coastal
counties.

Long term Tuesday night through Saturday
The mid-level ridge will remain in place Tuesday night through
Thursday, then finally flatten out Thursday night followed by zonal
flow on Friday. Surface high pressure will continue to dominate our
weather pattern. Models hint at a cold front approaching towards
Friday. But they also show it dissipating as it runs into our
persistently dry airmass. Temperatures should trend downward a few
degrees each day. However, they are still forecasted to remain well
above normal throughout the long term. Additionally, no rainfall is
in the forecast. Heat advisories, poor air quality, and dry fuels
that could increase the risk of wildfires are all concerns. But
there remain too many variables this far out to get to deep into the
details.

Aviation 04z Sunday through Thursday
Vfr.

Extended aviation outlook:VFR.

Marine
Rest of tonight: no highlights. A deep layer of high pressure
centered over the southern waters will produce south to
southwest winds 15 knots or less, and seas 2 feet or less
all waters.

Sunday through Thursday: the bermuda-azores high will remain
the dominate weather feature during this time, resulting in a
general SW flow that backs some during the day and veers some at
night. Even with sea breeze influences and the nocturnal low
level jet, winds will be mainly at or below 15 kt, with seas no
more than 2 or 3 ft.

Climate
A significant, prolonged heat wave will challenge or break many
of these records:
all time record highs for may:
kchs: 99 set may 21, 1938.

Ksav: 101 set may 30, 1898 and may 31, 1945.

Kcxm: 99 set may 21, 1938 and may 26, 1953.

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.
