.DISCUSSION...
/ISSUED 303 AM CDT WED MAY 6 2015/
UPPER RIDGING AND SURFACE HIGH PRESSURE CONTINUE TO BUILD WEST INTO
THE REGION TODAY. LIGHT WINDS INCREASING SLIGHTLY IN THE AFTERNOON
ALONG WITH MOSTLY SUNNY/CLEAR SKIES WILL PREVAIL THROUGH SATURDAY.
AFTERNOON CUMULUS CLOUDS DEVELOPING EACH DAY IS ALSO LIKELY.

HIGHS THE LAST TWO DAYS HAVE BEEN RUNNING A DEG OR TWO ABOVE
GUIDANCE AND ASSUME THAT WILL BE THE CASE THROUGH FRIDAY. HIGHS
TODAY WILL BE IN THE MIDDLE 80S AND SLIGHTLY WARMER ON THURSDAY
THANKS TO 850 TEMPS INCREASING SLIGHTLY. THURSDAY AND FRIDAY WILL
SEE HIGHS NEAR 90 FOR MANY LOCATIONS AND MID TO UPPER 80S ELSEWHERE.
DID NOT QUITE HIT 90 YET AS THERE IS STILL SOME UNCERTAINTY ON HOW
MUCH CLOUD COVER WILL BE PRESENT DUE TO A LOW OFF THE SOUTHEAST
COAST. OVERNIGHT LOWS WILL ALSO BE ON A WARMING TREND FROM UPPER 50S
TONIGHT TO THE MID 60S BY SUNDAY NIGHT.

THE PREVIOUSLY MENTIONED LOW PRESSURE SYSTEM IS FORMING OFF THE EAST
COAST OF FLORIDA TODAY AND WILL STRENGTHEN SLIGHTLY AND MOVE NORTH
NEAR THE SOUTH CAROLINA COAST ON FRIDAY. THIS WILL HOVER NEAR THE
SHORE THROUGH THE WEEKEND AND OFF TO THE NORTHEAST TUESDAY. GUIDANCE
CONTINUES TO SHOW THAT THIS LOW WILL HAVE LITTLE TO NO IMPACT ON THE
AREA OUTSIDE OF AN INCREASE IN MOISTURE/CLOUDS FOR SUNDAY-MONDAY.

AS THE LOW PRESSURE AREA IS SPINNING OFF TO THE EAST...A STRONG
SURFACE HIGH PRESSURE WILL REMAIN IN CONTROL OF THE SENSIBLE WEATHER
WITH NO PRECIPITATION EXPECTED THROUGH AT LEAST SATURDAY. ON
SUNDAY...A WEAK UPPER SHORTWAVE IS PROGGED TO PASS THROUGH THE AREA
WITH THE GFS CONTINUING TO INDICATE SOME SHOWER ACTIVITY WITH
IT...SO CONTINUED THE SLIGHT CHANCE OF SHOWERS/THUNDER DUE TO ENOUGH
INSTABILITY PRESENT TO GET A FEW RUMBLES. MONDAY WILL MOST LIKELY BE
DRY BUT WITH WEAK WAVES AROUND THE AREA AND TIMING
UNCERTAINTY...WILL CONTINUE THE SLIGHT CHANCE POPS.

A COLD FRONT THEN MOVES THROUGH THE AREA MONDAY NIGHT THROUGH
TUESDAY...KEEPING A CHANCE OF RAIN/SLIGHT CHANCE OF THUNDER IN THE
FORECAST. IT DOES NOT LOOK STRONG ENOUGH TO PRODUCE WIDESPREAD
THUNDERSTORMS AT THIS TIME. HIGH PRESSURE AND DRY WEATHER RETURN FOR
WEDNESDAY. TEMPS SUN-TUE STILL REMAIN IN THE LOWER TO MID 80S WITH
HIGHS WED BEHIND THE FRONT DROPPING TO THE MIDDLE TO UPPER 70S.
