PREVAIL. FORECAST SOUNDINGS/TIME-HEIGHT SECTIONS INDICATE THIS
PATTERN WILL GENERALLY HOLD TRUE FOR THE NEXT 24 HOURS SO VFR
CONDITIONS ARE RETAINED. BIG STORY LOOKS TO BE THE STRONG AND
GUSTY NRLY WINDS AS SFC OBS ARE SHOWING WINDS RUNNING 10+G20+ MOST
SITES THANKS TO A TIGHT PRESSURE GRADIENT IN PLACE. WINDS WILL GO
MAINLY LIGHT AROUND SUNSET AND HOLD THERE THROUGH THE NIGHT BEFORE
PICKING BACK UP TO AROUND 10 KNOTS AFTER SUNRISE TOMORROW.
