AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
245 PM CDT SAT AUG 16 2003
MAIN FORECAST PROBLEMS CONTINUE TO REVOLVE AROUND THE HEAT INDICES
AND THE CHANCES OF RAIN INTO THE EXTENDED FORECAST.
HEAT INDICES WILL REACH THE 105 TO AROUND 110 RANGE OVER NORTHWEST
PORTIONS OF THE CWFA THOUGHT MONDAY. HOWEVER...THE MIN TEMPERATURES
WILL REMAIN IN THE LOWER TO MIDDLE 70S DURING THE NIGHTTIME
HOURS...THUS NOT MEETING THE LOCAL HEAT ADVISORY CRITERIA. WILL KEEP
MENTIONING THE HIGH HEAT INDICES IN THE HWO FOR THE PRESENT.
OTHERWISE...SURFACE HIGH PRESSURE RIDGE WILL REMAIN IN PLACE FOR THE
FIRST HALF OF THE FORECAST PERIOD. OVERNIGHT A DYING MCS PENETRATED
THE VERY SOUTHEAST ZONES...AND CURRENTLY A SHORTWAVE TROUGH IS
POSITIONED OVER THE CENTRAL ZONES AND SPARKING A FEW SHOWERS AND
THUNDERSTORMS. MODELS ARE INDICATING THE SHORTWAVE CURRENTLY OVER
THE NORTHERN HALF OF GEORGIA WILL CONTINUE TO SLIDE SOUTHWEST DURING
THE OVERNIGHT HOURS...MUCH THE SAME TRACK AS THE OVERNIGHT
CONVECTION. ALL THE MODEL GUIDANCE SEEM TO PICK UP ON THIS
FEATURE...AND WILL HAVE THE HIGHEST POPS (30%) IN THE SOUTHEAST FOR
TONIGHT. NOT QUITE CONFIDENT THE CONVECTION WILL BE DIURNAL IN
NATURE...SO WILL LEAVE OUT MENTION OF EVENING ONLY POPS.
MORE HOT WEATHER ON TAP FOR SUNDAY AND MONDAY WITH TEMPS CONTINUING
INTO THE MIDDLE 90S. A WEAK FRONTAL BOUNDARY IS PROGGED TO APPROACH
THE NORTHERN PERIPHERY OF THE FORECAST AREA. NOT TOO CONFIDENT ON
THE EVOLUTION OF THIS SYSTEM...AND NO REAL FOCUSING MECHANISM FOR
CONVECTION ON SUNDAY...SO WILL KEEP THE ONGOING TREND OF MINIMAL
POPS AT THIS TIME.
IN THE EXTENDED...NO REAL CHANGES WERE MADE. THE PREVIOUSLY MENTIONED
FRONTAL BOUNDARY IS PROGGED TO STALL AND DISSIPATE OVER CENTRAL
AREAS OF THE CWFA. WILL CONTINUE THE TREND OF SCATTERED/ISOLATED
POPS...AND SEE WHAT LATER MODELS RUNS DO WITH THIS SYSTEM.
