What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Building heat through the week...

Synopsis
The region will remain situated between atlantic high pressure
and an inland trough of low pressure until late this week. The
trough of low pressure will then settle over the region and will
persist into early next week.

Near term through tonight
Isolated to scattered showers tstms will gradually transition
into the interior of southeast georgia through late afternoon
as the resultant sea breeze meanders inland. There are still
come cam members, including the h3r, that develop convection
over parts of the pee dee into the CAPE fear region along a
residual outflow that was left over from the MCS that moved
offshore of CAPE lookout earlier this morning. There are some
signals that this activity could make a run for the santee river
prior to dissipating just before sunset, but confidence in
getting measurable rainfall in northern berkeley or upper
charleston counties is quite low as goes-e water vapor imagery
suggests subsidence is increasing across the midlands into the
charleston metro area. Either way, convection should quickly by
early evening with dry conditions prevailing for the overnight
period.

Any convective debris cloudiness will thin dissipate during the
early-mid evening with mostly clear skies dominating through
the early morning hours Tuesday. It will remain warm and muggy
with lows ranging from the lower 70s inland to the upper
70s near 80 at the coast. Again, temperatures in downtown
charleston should bottom out within a degree or so of 80 and
could approach the record high minimum of 81 for the date; last
set in 2015.

Short term Tuesday through Thursday
Tuesday through Thursday: primary focus remains on the potential for
elevated heat index values during each afternoon. Tuesday afternoon,
maximum heat index values should top out in the 100-103f range at
most locations away from the immediate coast. Wednesday and
Thursday, temperatures in the mid upper 90s and dewpoints in the 70s
should support maximum heat index values in the 105-109f range away
from the beaches. Given our lower heat index threshold prior to july
1, if the current forecast does not require significant changes
we can expect to issue heat advisories for many areas both days.

Meanwhile, a strong upper ridge which will support this intense heat
will also limit coverage of afternoon evening thunderstorms Tuesday
and Wednesday. Thus, pm pops are limited to slight chance low chance
both days.

Wednesday night and Thursday: the upper ridge will begin to
weaken retreat south of the region. Meanwhile, a weakening
surface cold front will approach the region from the northwest.

The remnants of this front will settle into the region as a weak
surface low pressure trough of low pressure starting Thursday.

This scenario will create an environment more supportive of
showers thunderstorms. Per regional consensus, expanded slight
chance pops across the region starting Wednesday night, although
confidence in any nocturnal thunderstorms remains low.

Confidence is greater that at least scattered thunderstorms can
be expected Thursday, especially during the afternoon evening
hours.

Long term Thursday night through Sunday
A more active convective pattern is in store for the long range
period. As discussed within the short term forecast period, the
strong upper ridge will gradually weaken, allowing a transition to
weak upper trough pattern. Meanwhile, the remnants of a weak surface
cold front will have settled over the region as a surface low trough
of low pressure through the weekend, maintaining an environment
favorable for increased coverage of showers thunderstorms. Highs
each day will continue to top out in the lower mid 90s, with heat
indices around 105f each afternoon.

Aviation 18z Monday through Saturday
Vfr.

Extended aviation outlook: mainlyVFR outside any thunderstorms.

Marine
Tonight: typical summer southerly flow regime will hold in place
tonight. Winds will be south to southwest 10-15 kt with seas
1-3 ft.

Tuesday through Friday: typical south southwest winds and associated
seas 1-3 feet will prevail through Thursday. Even where winds are
locally enhanced by the daily sea breeze and by modest nighttime
surges of southwest winds, wind gusts should remain capped at 20
knots. As a surface low trough of low pressure settles over the
waters Friday through the weekend, wind direction will become less
uniform more changeable, but wind speeds seas are expected to remain
below small craft advisory levels. The exception could be locally
hazardous conditions within close to thunderstorms which should
become more common late week through the weekend.
