AREA FORECAST DISCUSSION...COR FOR TIME ISSUED
NATIONAL WEATHER SERVICE JACKSON MS
300 PM CDT FRI JUL 18 2003
MAIN FORECAST CHALLENGES REMAIN THE POPS THROUGH THE EXTENDED PERIOD.
MCS BARRELING DOWN ON THE FORECAST AT THIS TIME. BOTH THE ETA AND
AVN INDICATE THE SYSTEM WILL MOVE SOUTH ACROSS THE CWFA ALONG AND
WEST OF INTERSTATE 55. CURRENTLY...CAPES ARE ABOUT 5000 J/KG AND
LIS ARE -8 OVER THE NORTHWEST CWFA. VISIBLE IMAGERY SHOWS STORMS
ARE BEGINNING TO FIRE. WILL HAVE THE HIGHEST POPS WEST OF INTERSTATE
55 TONIGHT.
UPPER PATTERN TO STAY MUCH THE SAME THROUGH THE ENTIRE FORECAST
PERIOD WITH A TROUGH OVER THE EASTERN HALF OF THE COUNTRY AND A HIGH
OVER THE WEST. UPPER FLOW OVER THE CWFA WILL REMAIN NORTHWESTERLY
THROUGH THE ENTIRE PERIOD. HARD TO TIME SHORTWAVES WILL CONTINUE TO
MOVE SOUTH OVER THE CWFA IN THE MID LEVEL FLOW. THEY WILL CONTINUE
TO HELP FIRE CONVECTION...IN COMBINATION WITH A COUPLE OF SURFACE
FRONTAL BOUNDARIES AND THE VERY MOIST AND UNSTABLE AIRMASS IN
PLACE. STILL NOT WORDING THE CONVECTION DIURNAL IN NATURE AS THIS
TYPE OF PATTERN PRODUCES CONVECTION WELL AFTER SUNSET.
FOR TOMORROW...ANOTHER SHORTWAVE TO FOLLOW AND SHOULD TRACK RIGHT
ALONG THE SAME PATH. IN ADDITION...A FRONTAL BOUNDARY WILL BEGIN
APPROACHING THE NORTHERN PERIPHERY OF ZONES. THE SHORTWAVE SHOULD
HELP DRAG IT SOUTHWARD. THIS BOUNDARY SHOULD SET UP SHOP THROUGH THE
WEEKEND HELPING TO FOCUS CONVECTION. AVN INDICATING THAT THE FRONT SHOULD
BECOME DIFFUSE OVER THE CENTRAL CWFA BY EARLY MONDAY.
BY TUESDAY...ANOTHER FRONTAL BOUNDARY BEGINS APPROACHING THE NORTHERN
CWFA. THIS SYSTEM HAS POTENTIAL TO PRODUCE SOME STRONGER STORMS OVER
THE NORTHERN CWFA. AVN HAS A PRETTY IMPRESSIVE (FOR THIS TIME OF
YEAR) 90KT 250 MB JETMAX OVER MIDDLE TENNESSEE ON TUESDAY. THE
AVN/GFS HAS SOME SLIGHT DIFFERENCES IN THEIR SOLUTIONS WITH THIS
SYSTEM FROM YESTERDAYS RUN. THE MODELS HAVE FLATTENED THIS SYSTEM
OUT SOMEWHAT...AN HAS IT COMING IN SLIGHTLY EARLIER THAN YESTERDAY.
ALSO...IT HAS STALLED THE BOUNDARY ALONG THE COAST BY THURSDAY. WILL
NOT END UP CHANGING THE FORECAST MUCH PAST THE FIRST 24 HOUR
PERIOD...AS ONGOING FORECAST LOOKS TO HAVE THE TRENDS HANDLED VERY
WELL.

NORTHEAST LOUISIANA...AND EXTREME SOUTHEAST ARKANSAS .DAY ONE...TONIGHT AND SATURDAY... ...THUNDERSTORMS... SCATTERED SEVERE THUNDERSTORMS WILL BE POSSIBLE LATE FRIDAY AFTERNOON THROUGH SATURDAY AFTERNOON ACROSS LOCATIONS IN SOUTHEAST ARKANSAS...NORTHEAST LOUISIANA...AND MISSISSIPPI ALONG AND WEST OF INTERSTATE 55. ISOLATED SEVERE THUNDERSTORMS WILL BE POSSIBLE DURING THIS SAME TIME PERIOD FOR THE REST OF EASTERN MISSISSIPPI. THE MAIN RISK WITH STORMS WILL BE HIGH WINDS AND HAIL. A CONVECTIVE COMPLEX AND MID LEVEL DISTURBANCE IS FORECAST TO PUSH SOUTH INTO THE LOWER MISSISSIPPI VALLEY LATE FRIDAY AFTERNOON INTO FRIDAY EVENING. THUNDERSTORMS ASSOCIATED WITH THESE FEATURES ARE EXPECTED TO BEGIN TO AFFECT LOCATIONS IN THE DELTA REGION AND LOCATIONS IN NORTH CENTRAL MISSISSIPPI BEFORE MIDNIGHT. THE COMBINATION OF LARGE ATMOSPHERIC INSTABILITY PARAMETERS AND MODEST SHEAR WILL ALLOW SOME STORMS TO PRODUCE WINDS UP TO...OR OVER...60 MPH...AS WELL AS HAIL UP TO NICKEL SIZE. THESE STORMS SHOULD WEAKEN SOMEWHAT DURING THE EARLY MORNING HOURS...BUT COULD STILL BE SEVERE...AS THEY MOVE SOUTH TO THE INTERSTATE TWENTY CORRIDOR ALONG AND WEST OF THE JACKSON METROPOLITAN AREA. THE REMNANTS OF THESE STORMS AND THE POSSIBILITY OF ANOTHER CONVECTIVE COMPLEX WILL PROMPT MORE POTENTIALLY SEVERE STORMS ACROSS THE WESTERN HALF OF THE AREA BY MIDDAY SATURDAY. OTHERWISE...ANTICIPATE ISOLATED THUNDERSTORMS TO FORM FRIDAY AFTERNOON ACROSS EASTERN AND SOUTHERN MISSISSIPPI AND NORTHEAST LOUISIANA. MOST OF THIS ACTIVITY WILL END DURING THE EVENING. MORE WIDESPREAD CONVECTION SHOULD DEVELOP BY SATURDAY AFTERNOON IN EASTERN MISSISSIPPI. DUE TO HIGH INSTABILITY AND MINOR PULSES OF ENERGY ALOFT...THESE STORMS WILL ALSO HAVE THE POTENTIAL TO PRODUCE HAIL AND DAMAGING WINDS. ...FLOODING... THE COMPLEX OF THUNDERSTORMS EXPECTED TO AFFECT PORTIONS OF NORTHEAST MISSISSIPPI...SOUTHEAST ARKANSAS...AND NORTHEAST LOUISIANA FRIDAY EVENING AND EARLY SATURDAY MORNING COULD BRING 1 TO 2 INCHES OF RAINFALL TO LOCATIONS IN THE AREA. COMBINED WITH LOCALLY HEAVY RAINFALL FROM THURSDAY...PRECIPITATION AMOUNTS OF THIS MAGNITUDE WILL CREATE AREAS OF PONDING WATER...ESPECIALLY IN LOW LYING AREAS. ADDITIONAL HEAVY RAIN COULD FALL ACROSS THESE SAME LOCATIONS LATER ON IN THE DAY SATURDAY. ...SEASONAL THREATS... A HOT AND HUMID AIRMASS WILL REMAIN OVER PORTIONS OF THE REGION FOR ONE MORE AFTERNOON AS AN UPPER LEVEL HIGH PRESSURE SYSTEM REMAINS IN CONTROL. HEAT INDICES WILL RANGE FROM 105 TO 110 DEGREES...MAINLY OVER THE MISSISSIPPI DELTA REGION FRIDAY AFTERNOON...AS TEMPERATURES REACH THE MID TO UPPER 90S. CONDITIONS SHOULD NOT BE QUITE AS HOT SATURDAY AFTERNOON AS WIDESPREAD CLOUD COVER AND SCATTERED PRECIPITATION ARE EXPECTED TO KEEP TEMPERATURES LOWER. .DAYS TWO THROUGH SEVEN...SATURDAY NIGHT THROUGH FRIDAY... ...DAYS TWO AND THREE...SATURDAY NIGHT THROUGH MONDAY... TURBULENT NORTHWEST FLOW WILL CONTINUE IN THE MID AND UPPER LEVELS OF THE ATMOSPHERE SUNDAY AND MONDAY. A WEAK FRONTAL BOUNDARY AT THE SURFACE WILL MEANDER ACROSS THE LOWER MISSISSIPPI BOTH DAYS. THE INFLUENCE OF THIS BOUNDARY...ALONG WITH OTHER TRANSIENT BOUNDARIES...WILL COMBINE WITH PULSES OF ENERGY ALOFT AND ATMOSPHERIC INSTABILITY TO PRODUCE MORE THUNDERSTORMS THROUGHOUT THE AREA. THUNDERSTORMS WILL BE MOST NUMEROUS DURING AFTERNOON AND EVENING HOURS AND WILL HAVE THE POTENTIAL TO PRODUCE DAMAGING WINDS GUSTS AND SMALL HAIL. ...DAYS FOUR THROUGH SEVEN...MONDAY NIGHT THROUGH FRIDAY... ISOLATED TO SCATTERED STRONG TO SEVERE THUNDERSTORMS WILL CONTINUE TO BE POSSIBLE ACROSS THE ENTIRE LOWER MISSISSIPPI VALLEY THROUGH TUESDAY AS A FAVORABLE UPPER LEVEL PATTERN IS FORECAST TO BRING A UNUSUALLY STRONG SUMMER COLD FRONT THROUGH. THIS FRONT...AND THE ASSOCIATED STRONG STORMS...ARE LIKELY TO REMAIN IN THE VICINITY OF SOUTHERN MISSISSIPPI ON WEDNESDAY. .SPOTTER CALL TO ACTION STATEMENT... THE ACTIVATION OF STORM SPOTTERS...HAM RADIO OPERATORS...AND EMERGENCY MANAGEMENT PERSONNEL IN SUPPORT OF SEVERE WEATHER OPERATIONS...MAY BE NEEDED THROUGH TONIGHT.
