NWS Jackson, MS wrote its last area forecast discussion before the first event at May 15, 2:20 PM CST, 1 hour 2 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 320 PM CDT FRI MAY 15 2009 .DISCUSSION... THIS AFTN/TONIGHT... AS OF THIS DISCUSSION...CONVECTION IS STILL STRUGGLING TO INCREASE IN COVERAGE AND INTENSITY ALONG SEA-BREEZE INDUCED BOUNDARY THAT IS SLOWLY SHIFTING NORTH...HOWEVER THERE IS STILL A LOT OF INSOLATION LEFT THIS AFTN AND ACTIVITY MAY STILL INCREASE OVER THE NEXT COUPLE OF HOURS. FORECAST THINKING IS STILL THE SAME AS IT WAS THIS MORNING: A SUBTLE MID LEVEL TROUGH AXIS...PRECIPITABLE WATER AIRMASS >1.5 INCHES...AND PLENTY OF INSOLATION ARE COMBINING TO CREATE A MOIST AND VERY UNSTABLE AIRMASS OVER THE FORECAST AREA WITH MIXED LAYER CAPE >2500 J/KG. SHEAR IS SUMMER-LIKE AND IS SUPPORTING SCATTERED DISORGANIZED CONVECTION WITH CONTINUED HEATING. 12Z LOCAL WRF RUNS SHOWED SCATTERED AFTN SHOWER/TSTM DEVELOPMENT...ESPECIALLY ALONG AND EAST OF THE NATCHEZ TRACE CORRIDOR AND THIS SHOULD CONTINUE UNTIL ABOUT SUNSET. KJAN MORNING MODIFIED SOUNDING SHOWS AN 850-500MB TEMP DIFFERENCE OF 29F AND SUBSTANTIAL DCAPE SUGGESTING A FEW SEVERE WET MICROBURSTS WILL BE POSSIBLE WITH THE PULSE TYPE STORMS. AS THE SUN SETS...THE CONVECTION WILL FIZZLE OUT LEADING TO A QUIET WEATHER NIGHT. SATURDAY AND SATURDAY NIGHT...A MAJOR POLAR STREAM SHORTWAVE TROUGH WILL SEND A STRONG COLD FRONT INTO NORTHERN PORTIONS OF THE ARKLAMISS SATURDAY EVENING. THE FRONT WILL PASS THROUGH THE ENTIRE AREA BY LATE SUNDAY MORNING. AHEAD OF THE FRONT...THE AIR WILL BECOME VERY UNSTABLE SATURDAY AFTN WITH MIXED LAYER CAPE >2000 J/KG. SHEAR WILL BE WEAK AHEAD OF THE FRONT AND EXPECT SCATTERED DISORGANIZED CONVECTION TO DEVELOP BY LATE MORNING/AFTN. AS THE FRONT MOVES INTO THE AREA LATE SATURDAY...INCREASING SHEAR (0-6KM 20 TO 30KT) AND STRONG LOW-LEVEL CONVERGENCE WILL HELP TO ORGANIZE CONVECTION MAKING FOR FAIRLY WIDESPREAD COVERAGE OF SHOWERS/TSTMS SAT NIGHT. A FEW STRONG TO SEVERE STORMS SEEM PLAUSIBLE BASED ON LATEST GUIDANCE...AND PRECIP WATER VALUES GREATER THAN 1.5 INCHES WILL SUPPORT SOME HEAVY RAIN. THE GFS INDICATES SOME BACKING OF THE FLOW ABOVE THE FRONTAL INVERSION SUNDAY MORNING THAT COULD RESULT IN A SECOND WAVE OF LESS CONVECTIVE RAIN/ISOLATED TSTMS NORTH OF THE SURFACE BOUNDARY. IF THIS WERE TO OCCUR...HEAVY RAINFALL COULD BECOME A CONCERN. THE 12Z ECMWF AND GFS ENSEMBLE MEAN ARE NOT AS BULLISH WITH THIS SCENARIO AND ACTUALLY GENERATE VERY LITTLE PRECIP FOR SUNDAY...SO THERE IS STILL SOME UNCERTAINTY. REGARDLESS OF THE PRECIPITATION COVERAGE SUNDAY...THERE WILL BE MUCH COOLER AIR PUSHING INTO THE AREA. SHOULD CLOUDS/RAIN LINGER...IT WILL MAKE FOR AN ATYPICALLY COOL MID MAY DAY WITH TEMPERATURES PERHAPS FALLING INTO THE 50S AND HOLDING THERE FOR A WHILE. /EC/ SUNDAY NIGHT THROUGH FRIDAY...A 1030MB+ SURFACE HIGH PROGGED TO SLIDE FROM THE MID MS VALLEY SUNDAY NIGHT INTO THE OH VALLEY MONDAY. THIS SYSTEM WILL GIVE US SOME DRIER/MUCH COOLER AIR FOR THE FIRST FEW DAYS OF NEXT WEEK AS IT MOVES EWD. PWATS DROP TO LESS THAN 0.35 INCHES ON MONDAY AS JUST ABOUT ALL MODELS SHOW 850MB TEMPS DOWN TO AT LEAST 10C OR SLIGHTLY COOLER. THESE VALUES WOULD TRANSLATE TO LOWS 48-53F AND HIGHS 71-75F DEPENDING ON LINGERING HIGH LEVEL CLOUD COVER WITH UPPER TROUGH PASSAGE. GFS HAS BACKED OFF ON LIMITED MOISTURE RETURN WWD ACROSS THE GULF STATES TUESDAY AND CHOOSING INSTEAD TO DEVELOP A MORE ROBUST VERTICALLY STACKED CIRCULATION IN THE SERN GULF WEDNESDAY/THURSDAY. THIS CRITICAL FEATURE WILL PROBABLY BACK WWD ACROSS THE GULF ON FRIDAY ALTHOUGH THE ECMWF IS NOW HOLDING IT OVER FL LONGER AND INTO THE MEMORIAL DAY WEEKEND. THE NET RESULT WILL BE SEVERAL DAYS OF NELY FLOW IN THE LOW LEVELS FOR OUR REGION WITH OVERNIGHT LOWS IN THE 50S THROUGH THE MIDDLE OF THE WEEK. WILL MAINTAIN SOME LOWER END POPS BY THURSDAY OVER MAINLY SERN MS AND WILL BOOST THEM SLIGHTLY HEADING INTO FRIDAY. EXPECT COOLEST DAYTIME HIGHS WILL COME ON SUNDAY WITH NLY LOW LEVEL FLOW AND EXTENSIVE CLOUD/RAIN SHIELD CONTINUING WITH CAA BEHIND THE FRONT. LOWS BOTH MONDAY AND TUESDAY MORNINGS WILL DIVE TO AT LEAST THE 50-55F RANGE WITH A FEW U40S LOOKING MORE PROBABLE EACH MORNING (PROBABLY FOR THE LAST TIME THIS SPRING). RECORD LOWS FOR EARLY NEXT WEEK ARE GENERALLY IN THE MIDDLE 40S. THE COOL AIR WILL NOT LAST TOO LONG AS RIDGING AT THE MID AND UPPER LEVELS BUILDS INTO THE REGION. PLENTY OF DAILY SUN WILL HELP MODIFY THE AIR MASS TO BRING BACK NEAR NORMAL HIGH TEMPERATURES TO THE ARKLAMISS REGION FOR WEDNESDAY THROUGH FRIDAY. /40/ && .AVIATION...SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE TO MOVE NORTH INTO THE REGION THROUGH THE REMAINDER OF THE AFTERNOON AND EARLY EVENING BEFORE DISSIPATING AFTER SUNSET. KHBG WILL LIKELY BE THE TAF SITE MOST AFFECTED...THOUGH AN ISOLATED SHOWER/STORM NEAR KGLH...KGWO...OR KJAN IS NOT OUT OF THE QUESTION. VFR CONDITIONS WILL PREVAIL THROUGH THIS EVENING...WITH THOSE SITES MENTIONED POSSIBLY SEEING MVFR CONDITIONS DUE TO RESTRICTED VISIBILITY AND HEAVY RAINFALL AT TIMES. THE REGION WILL REMAIN RATHER QUIET IN THE OVERNIGHT HOURS WITH AGAIN THE POSSIBILITY OF SEEING LOW CLOUDS AND PATCHY FOG IN THE EARLY MORNING...ESPECIALLY AT KHBG AND KMEI. THIS SHOULD DISSIPATE BY 14-15Z. A COLD FRONT IS PROGGED TO MOVE THROUGH THE REGION SATURDAY NIGHT INTO SUNDAY AND THIS WILL LIKELY AFFECT AIR TRAVEL DURING THIS TIME. /28/ && .JAN WATCHES/WARNINGS/ADVISORIES... MS...NONE.
