Area Forecast Discussion
National Weather Service Charleston SC
1211 AM EDT Mon Apr 22 2019

.SYNOPSIS...
High pressure will prevail with dry weather through Thursday. A
storm system will then bring unsettled weather late in the
week. 

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
Lowered coastal winds to calm where observations are showing
winds 2 kt or less. Made minor adjustments to hourly
temperatures and dewpoints.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH WEDNESDAY/...
High confidence this period with no significant weather expected. 
High pressure across the area Tuesday will shift offshore as a lee-
side trough sets up inland toward mid week. Temperatures will warm 
through the period as a southerly return flow sets up, staying 
mainly above normal through the period.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
High pressure will shift further offshore Wednesday night into 
Thursday as a cold front approaches from the north and a storm 
system approaches from the west. The storm system with its 
associated cold front is expected to move through the region on 
Friday, bringing showers and cooler temperatures. Saturday, the 
models differ on whether it will be dry or remnant showers will 
persist. Since most of the models lean towards it being dry, we 
trended our forecast in that direction.

&&

.AVIATION /04Z MONDAY THROUGH FRIDAY/...
VFR.

Extended Aviation Outlook: VFR.

&&

.MARINE...
Tonight: No major changes were made.

Monday through Friday: High pressure will prevail with no 
significant concerns, although the pressure gradient will increase 
mid to late week due to an inland trough and then a cold front which 
will lead to slightly increasing winds/seas. The strongest winds 
will generally be near the coast each afternoon due to the sea 
breeze, possibly nearing Advisory levels in Charleston Harbor 
starting Wednesday.
