.Short term...
TONIGHT THROUGH WEDNESDAY NIGHT...A convergence to the northeast
will spread numerous showers and isolated thunderstorms across the
islands tonight. RAOB from this afternoon depicts a conditional
unstable profile. A surface trough to the south southwest will
continue southwest. A high pressure farther south will slowly move
east during the week. The convergence will remain across the
islands tonight through Wednesday. Winds will again diminish to
variable on Wednesday night as a shortwave trough moves west.

tonight through Wednesday. On Wednesday night, showers will
subside to scattered and winds to light and variable.

.Long term...

strengthen on Friday and enhance east winds across the islands on
Friday morning. New resolutions are now holding most of the

across the islands during the long term.
