DISCUSSION
KEY MESSAGE 1
ISOLATED STORMS POSSIBLE THIS AFTERNOON; ABOVE
NORMAL TEMPERATURES CONTINUE.
LATEST SURFACE ANALYSIS SHOWS DEEPENING LOW PRESSURE NEAR THE
ILLINOIS/INDIANA BORDER, ASSOCIATED WITH THE NEXT FRONTAL SYSTEM
DUE TO ENTER THE CAROLINAS LATE TONIGHT.
PRIOR TO THIS FRONT, RELATIVELY FLAT STEERING FLOW WILL
CONTINUE, IN BETWEEN A FEW WEAK SHORTWAVES. DESPITE PRECIPITABLE
WATER VALUES ABOVE 1.8", DRIER AIR IN THE MID-LEVELS WILL HELP
SUPPRESS CONVECTIVE ACTIVITY THIS AFTERNOON. SEABREEZE MAY TRY
TO INITIATE A FEW STORMS, WHICH WILL PUSH INLAND FROM THERE.
PLENTY OF INSTABILITY TO WORK WITH, AND THE DCAPE HOVERS AROUND
1200 J/KG, SO ISOLATED STORMS HAVE THE POTENTIAL TO PRODUCE
DAMAGING WIND GUSTS. OVERALL THOUGH, SEVERE WEATHER ACTIVITY
SHOULD BE DISPLACED TO THE NORTH. HIGHS GET INTO THE LOW-TO-MID
90S INLAND, UPPER 80S AT THE COAST. TRIPLE DIGITS EXPECTED FOR
THE INLAND AREAS, BUT WILL FALL SHORT OF HEAT ADVISORY CRITERIA
(105 DEGREES).
FRONT WILL MOVE THROUGH THE AREA TUESDAY, BRINGING SOME BETTER
RAIN CHANCES WITH IT, THOUGH LACKLUSTER SHORTWAVE ENERGY WEAKENS
THE SYSTEM. NO DAY IN PARTICULAR THIS WEEK APPEARS TO BE A
WASHOUT, SO DROUGHT RELIEF DOES NOT APPEAR TO BE LIKELY. TRIPLE
DIGIT HEAT INDICES WILL BE IN PLAY FOR MOST OF THIS WEEK, WHERE
HEAT ADVISORIES MAY BE NEEDED BY THE WEEKEND. STILL EXPECTING
BETTER MOISTURE RETURN ON FRIDAY, BRINGING THE BEST RAIN AND
STORM CHANCES OF THE WEEK, BUT FORECAST GUIDANCE HAS TRENDED
DOWNWARD A BIT THIS CYCLE.
AVIATION /10Z MONDAY THROUGH FRIDAY/
AREAS OF LOW STRATUS HAVE DEVELOPED INLAND FROM THE COAST AND
HAVE A MODERATE POTENTIAL TO AFFECT KLBT THROUGH 12Z. THERE IS A
DECREASING PROBABILITY FOR IMPACTS BETWEEN 12-14Z WHEN VFR
CONDITIONS SHOULD DEVELOP AT KLBT. STRATUS HAS A LOW POTENTIAL
TO AFFECT FLO THROUGH 12-13Z. PREVAILING VFR CONDITIONS THE
REMAINDER OF THE DAY HAVE ONLY A LOW POTENTIAL TO BECOME
INTERRUPTED BY ISOLATED SHOWERS AND THUNDERSTORMS. THESE COULD
AFFECT KILM AFTER 16Z ALONG THE SEABREEZE FRONT, AND KLBT/KFLO
AFTER 18Z IN ASSOCIATION WITH AN UPPER LEVEL SHORTWAVE MOVING
EASTWARD. ANY LINGERING CONVECTIVE ACTIVITY SHOULD DISSIPATE
WITH THE LOSS OF DAYTIME HEATING THIS EVENING.
EXTENDED FORECAST...MAINLY VFR. BRIEF MVFR/IFR CONDITIONS ARE
POSSIBLE DURING SCATTERED AFTERNOON AND EVENING STORMS ON
TUESDAY AND AGAIN ON FRIDAY.
MARINE
THROUGH TONIGHT...SSW WINDS AT A GENTLE TO MODERATE BREEZE WILL
BUILD UP TOWARDS A FRESH BREEZE OUT OF THE SW BY TONIGHT. GUSTS
UP TO 20-23 KTS LIKELY, AND IT WOULDN'T BE SURPRISING IF THEY
SURPASSED 25 KTS AT TIMES. BUT I'M NOT SURE YET IF THE GRADIENT
WINDS WILL BE CONSISTENT ENOUGH TO WARRANT A SMALL CRAFT
ADVISORY OVER THE NORTHEAST SC WATERS. HOLDING OFF ON THAT IDEA
FOR NOW. SEAS AT 1-2 FT INCREASE WITH THE WIND, UP TO 2-4 FT
OVER THE COASTAL WATERS OUT 20 NM, AND 4-5 FT OUT 60 NM.
TUESDAY THROUGH FRIDAY...FRESH BREEZE OUT OF THE SW CONTINUES
FOR MUCH OF TUESDAY AHEAD OF A COLD FRONT. THE FRONT MOVES
THROUGH TUESDAY NIGHT, QUICKLY VEERING THE WINDS TO THE NW AND
THEN NE BY WEDNESDAY MORNING, IMPROVING TO A MODERATE BREEZE.
ONSHORE FLOW BEGINS AGAIN WEDNESDAY EVENING, WITH SEAS IMPROVING
TO 2-3 FT. WINDS VEER TO THE SSW AGAIN THURSDAY NIGHT THROUGH
FRIDAY, INCREASING TO A FRESH BREEZE ONCE MORE. SEAS INCREASE
SLIGHTLY TO 3-4 FT.
