AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
249 PM CDT WED JUN 18 2014

.SHORT TERM...
NOT MUCH IN THE WAY OF ANY SIGNIFICANT CHANGES TO GOING FORECAST THIS
AFTERNOON. CONVECTIVE FORECAST FOR THIS AFTERNOON PRETTY MUCH WORKING
OUT AS EXPECTED AS WIDELY SCT SHRA/TSRA HAVE DEVELOPED OVER AL INTO
EXTREME E MS. EXPECT THIS ACTIVITY TO CONTINUE TO BUILD WEST THROUGH
THE AFTERNOON AND EVENING BEFORE DISSIPATING WITH SUNSET. EXPECT THAT
STRATUS AND FOG WILL REMAIN PATCHY LATER TONIGHT AS BEST LOW LEVEL
GULF INFLOW REMAINS FOCUSED TO THE WEST. MODELS IN GOOD AGREEMENT
THAT LOW/MID LEVEL ANTICYCLONE WILL SLOWLY BUILD AND RETROGRADE WEST
ACROSS THE AREA. PRECIPITABLE WATER VALUES ARE FORECAST TO INCREASE
SLIGHTLY ACROSS THE AREA...SO BY FRIDAY WILL CARRY SLIGHT CHANCE POPS
FOR DIURNAL CONVECTION AREAWIDE. WHILE THERE WILL BE ENOUGH LAPSE
RATE AND DCAPE TO POTENTIALLY SUPPORT A FEW STRONGER STORMS WITH
GUSTY WINDS...GIVEN OVERALL ACTIVITY REMAINING ISOLATED WITH LITTLE
LARGER SCALE SUPPORT FOR CONVECTION...DO NOT SEE ANY NEED TO INCLUDE
ANYTHING IN HWO AT THIS POINT. GUIDANCE TEMPS LOOK FINE. PREVIOUS
LONG TERM DISCUSSION FOLLOWS.                            /AEG/

.LONG TERM...
TYPICAL HOT AND HUMID SUMMERTIME CONDITIONS FOR THE LOWER MS VALLEY
REGION ARE ANTICIPATED FRIDAY AND SATURDAY WITH PREVALENCE OF
SUBTROPICAL RIDGING ALOFT IN THE VICINITY BRINGING MAINLY DRY
WEATHER WITH AFTERNOON HEAT INDEX VALUES PEAKING AROUND 100 DEGREES.
THERE COULD BE ISOLATED AND MAINLY AFTERNOON SHOWERS AND
THUNDERSTORMS...BUT MAINLY OVER THE EASTERN HALF OF THE FORECAST
AREA WHERE THERMAL CAPPING WILL BE A BIT LESS AND DEPTH OF QUALITY
LOW LEVEL MOISTURE GREATER. HOT ACTUAL TEMPERATURES IN THE MID 90S
AND LIKELY MODERATE DEVELOPING DCAPE COULD DELIVER AT LEAST MODEST
WET MICROBURST POTENTIAL TO MORE VIGOROUS CONVECTION THOSE
DAYS...BUT THE RISK DOES NOT WARRANT MENTION IN THE HWO YET.

BY SUNDAY MODELS STILL SHOW GOOD AGREEMENT THAT THE AFOREMENTIONED
UPPER RIDGE IN THE VICINITY WILL BE BREAKING DOWN SOME AND SHIFTING
FURTHER WEST. THIS WILL ALLOW A MORE ACTIVE NORTHWEST FLOW PATTERN
TO TEMPORARILY DEVELOP WHILE AT LEAST MINOR LOW LEVEL BOUNDARIES
DROP INTO THE REGION FROM THE NORTH LATER SUNDAY AND MONDAY. NO BIG
COLD FRONTS LOOK TO COME IN (AND IT IS GETTING TOO LATE INTO THE
SUMMER TO HOPE FOR THAT) SO HOT CONDITIONS WILL PROBABLY INITIALLY
ONLY BE HELPED A LITTLE BY GREATER AFTERNOON CLOUD AND SHOWER
COVERAGE. AS MENTIONED IN PRIOR DISCUSSIONS...THIS PERIOD WILL HAVE
TO BE MONITORED FOR ISOLATED SEVERE STORM POTENTIAL IN ESPECIALLY
NORTHERN ZONES BUT FOR NOW THE THREAT IS NOT OF HIGH ENOUGH CALIBER
TO YET INCLUDE IN THE HWO.

INTO THE MID-WEEK PERIOD THE MODEL GUIDANCE CONSENSUS IS THAT A WEAK
UPPER LEVEL TROUGH AXIS WILL SHARPEN AND ANCHOR JUST TO OUR WEST AND
PROMOTE BACKING LOW LEVEL WINDS AND LESS HEAT. HOWEVER...ATMOSPHERIC
COLUMN MOISTURE IN OUR REGION SHOULD INCREASE AND THE PRESENCE OF
THE SYNOPTIC TROUGH IN COMBINATION WILL LIKELY BRING THE REGION
ABOVE AVERAGE RAINFALL CHANCES FOR AT LEAST A FEW DAYS. /BB/

&&

.AVIATION... VFR CONDITIONS WILL PREVAIL TODAY THROUGH TONIGHT.
ISOLATED SHOWER/ TSTM ACTIVITY WILL BE PRESENT ESPECIALLY IN THE EAST
BUT TOO SPARSE TO INCLUDE IN THE TAFS AT THIS TIME. ANOTHER ROUND OF
MVFR TO IFR CONDITIONS WILL BE POSSIBLE BEFORE SUNRISE THURSDAY
MORNING. /28/
