SYNOPSIS
DRY HIGH PRESSURE WILL REMAIN THE PRIMARY FEATURE ACROSS THE
AREA THROUGH THE WEEKEND.
NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/
CLEAR SKY WITH LIGHT TO CALM WINDS SHOULD PROVIDE STRONG
RADIATIONAL COOLING CONDITIONS THIS EVENING. BY LATE TONIGHT,
THE CENTER OF HIGH PRESSURE MAY SLIP SOUTH ACROSS FL/GULF,
RESULTING IN A SLIGHT INCREASE IN THE PRESSURE GRADIENT ACROSS
THE AREA. AS A RESULT, SOUTHWEST WINDS MAY INCREASE TO 5 TO 10
MPH. THE INCREASED MIXING MAY RESULT IN STEADY TO SLIGHT WARMING
OF HOURLY TEMPERATURES DURING THE PRE-DAWN HOURS. LOW
