DISCUSSION

A SURFACE ATLANTIC RIDGE STRETCHES WESTWARD ACROSS FLORIDA AND HAS
CARRIED IN A SAHARAN AIR LAYER HAS SPREAD ACROSS THE AREA. THIS
ALONG WITH THE LOWER LEVEL HIGH CENTERED ACROSS OUR BROADER AREA
HAS RESULTED IN QUITE STABLE CONDITIONS. WHILE SURFACE CONDITIONS
ARE SEASONABLE, WITH TEMPERATURES IN THE MID 80S AND DEW POINTS IN
THE MID 70S, THERE IS A HEALTHY INVERSION BASED A BIT BELOW 900 MB
WITH CONSIDERABLE DRY AIR THROUGH THE LOWER LEVELS. AS A RESULT,
SHOWER ACTIVITY HAS BEEN ALL BUT ABSENT ACROSS THE FORECAST AREA
THROUGH THE EVENING. WITH THAT SAID, THERE HAS BEEN LIMITED
SHOWER AND THUNDERSTORM ACTIVITY NOT TO FAR AWAY OVER AND NEAR
SOUTH FLORIDA.
SURFACE THROUGH LOWER LEVEL RIDGING WILL CONTINUE TO DOMINATE
THROUGH THE OVERNIGHT PERIOD, ALONG WITH THE SAHARAN AIR. THIS
SHOULD HELP TO CURTAIL CONVECTIVE ACTIVITY. DIME POPS MAY BE
HIGH GIVEN THE ENVIRONMENT. HOWEVER IT IS DIFFICULT TO REMOVE POPS
COMPLETELY GIVEN THE SMATTERING OF ACTIVITY TO OUR NORTH AND EAST.
EXPECT SURFACE WINDS TO REMAIN GENTLE OUT OF THE EAST TO
SOUTHEAST. THIS STEADY BREEZE WILL MAINTAIN SEASONABLY WARM
CONDITIONS WITH LOWS IN THE LOWER 80S. DEW POINTS SHOULD LINGER IN
THE MID 70S.
