AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
315 PM CDT THU AUG 6 2015
.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT... AS OF MID AFTERNOON
SHOWERS AND THUNDERSTORMS WERE TRACKING EAST ACROSS NORTH
MISSISSIPPI. THIS WAS ASSOCIATED WITH A DECENT SHORTWAVE MOVING
OVER THE REGION WITH A SURFACE FRONT OVER THE MIDSOUTH. LATEST WATER
VAPOR SHOWED THE 500 MB HIGH CENTER OVER THE SOUTHERN PLAINS...THUS
CONTINUING NORTHWEST FLOW OVER THE REGION. MESO ANALYSIS CONTINUES
TO SHOW GOOD FLOW AROUND THIS SHORTWAVE OVER THE REGION. SO WILL
CONTINUE THE RISK OF SOME SEVERE STORMS OVER A GOOD PORTION OF THE
REGION FOR THIS AFTERNOON INTO THIS EVENING. THE PRIMARY RISK WILL
BE GUSTY WINDS TO 60 MPH AND SOME LOCALLY HEAVY DOWNPOURS. LATEST
HIRES MODEL RUNS SHOWS OUR RAIN CHANCES CONTINUING OVERNIGHT OVER
THE NORTHERN AND EASTERN AREAS. AS WE GO INTO FRIDAY THE SURFACE
BOUNDARY WILL BE STATIONARY OVER THE NORTHEAST AREA. THERE MAY BE A
RISK OF A FEW SEVERE STORMS RIDING DOWN THE BOUNDARY DURING THE DAY.
HOWEVER THAT WILL DEPEND ON HOW THINGS PAN OUT OVERNIGHT INTO FRIDAY
MORNING. MODELS DO SHOW SOME LOW LEVEL FORCING OF 0-3 KM WILL MOVE
ACROSS THE EASTERN AREAS ON FRIDAY. SPC HAS A LARGE MARGINAL RISK
FOR THE REGION. SO WITH THIS IN MIND WILL HOLD OFF ON MENTIONING ANY
LIMITED RISK OF SEVERE. WILL LET THE MID SHIFT TAKE A CLOSER LOOK AT
THAT POTENTIAL. OTHERWISE EXPECT A HOT DAY FOR FRIDAY WITH HIGHS IN
THE MIDDLE 90S TO AROUND 100. SO WITH THE 70S DEWPOINTS HAVE OPTED
TO PUT A HEAT ADVISORY FOR FRIDAY IN THE WESTERN AREAS WITH HEAT
INDICES FROM 106 TO 110 DEGREES. AS WE GO INTO FRIDAY NIGHT OUR
CHANCES OF CONVECTION WILL CONTINUE OVERNIGHT AS SOME MODELS TRY TO
BRING AN MCS ACROSS THE REGION FROM FRIDAY AFTERNOON INTO FRIDAY
NIGHT.
FOR SATURDAY INTO SATURDAY NIGHT...OUR CHANCES OF RAIN WILL START TO
DECREASE AS THE UPPER RIDGE BUILD TOWARD THE REGION FROM THE WEST.
MODELS BRING SOME LOWER POPS ACROSS THE SOUTHEAST...WHICH WILL
DISSIPATE BY SATURDAY NIGHT. IT WILL BE ANOTHER WARM DAY WITH HIGHS
FROM THE MIDDLE 90S EAST TO THE LOWER 100S WEST. ANOTHER ROUND OF
HEAT ADVISORIES WILL PROBABLY BE NEEDED FOR SATURDAY./17/
.LONG TERM...SUNDAY THROUGH WEDNESDAY...WE COULD SEE SOME OF THE
HOTTEST WEATHER SO FAR THIS SUMMER ESPECIALLY SUNDAY AND MONDAY. A
RATHER LARGE UPPER RIDGE WILL BE CENTERED ACROSS TEXAS AND PORTIONS
OF THE DEEP SOUTH ON SUNDAY. IN FACT...THE RIDGE LOOKS TO STRENGTHEN
EVEN ON SUNDAY. THIS WILL MEAN HEAT AND HUMIDITY WILL REMAIN WITH US
ON SUNDAY AND APPROACH EVEN MORE DANGEROUS LEVELS THAN WHAT WE HAD
BEEN SEEING. MANY LOCATIONS WILL SEE HIGHS OVER THE WEEKEND REACH
AND WELL EXCEED THE CENTURY MARK AND LIKELY FLIRT WITH RECORDS BUT
THE COMBINATION OF THIS HEAT WITH THE HUMIDITY WILL ALLOW HEAT
INDICES TO RANGE FROM 110-115 ACROSS THE DELTA REGION. OTHER
LOCATIONS WILL SEE HEAT INDICES OF 105-110 DEGREES. WILL CONTINUE
WITH THE SIGNIFICANT/ELEVATED RISKS IN THE HWO AND HEAT ADVISORIES
WILL LIKELY BE NEEDED AS THE TIME APPROACHES WITH EXCESSIVE HEAT
WARNINGS ALSO LIKELY FOR THE DELTA REGION.
HEADING INTO THE WORK WEEK...THE UPPER RIDGE BEGINS TO LOOSEN ITS
GRIP OVER THE ARKLAMISS REGION EVER SO SLIGHTLY. THE CENTER OF THE
RIDGE WILL SHIFT A LITTLE TO THE WEST AND HEIGHTS WILL FALL SOME
ACROSS THE AREA ON MONDAY. HOWEVER...IT WILL STILL BE PLENTY HOT ON
MONDAY ESPECIALLY ACROSS MY WESTERN COUNTIES AND PARISHES. MODELS
INDICATE THAT A FRONT WILL DROP SOUTH ACROSS THE CENTRAL AND EASTERN
PORTIONS OF MY CWA. THIS MAY BRING SOME RELIEF IN THE FORM OF RAIN
AND STORMS DURING THE AFTERNOON. THE FRONT WILL STALL ALONG OR SOUTH
OF THE I-20 CORRIDOR AND BRING PERHAPS SOME BETTER CHANCES FOR RAIN
ON TUESDAY BUT THE HEAT WILL REMAIN. ON WEDNESDAY...MODELS INDICATE
THAT SOME DRIER AIR WILL FILTER INTO THE REGION AS HIGH PRESSURE AT
THE SFC TRIES TO NOSE IN FROM THE NORTH AND A RATHER LARGE UPPER LOW
DIPS SOUTHWEST FROM CANADA AND TAKES UP RESIDENCE ACROSS THE
EASTERN HALF OF THE COUNTRY THROUGH THE END OF THE WEEK. PW VALUES
ARE DEPICTED TO DROP TO LESS THAN AN INCH ACROSS THE AREA BY
THURSDAY AFTERNOON. THIS WILL MAKE TEMPERATURES FEEL MUCH MORE
BEARABLE FOR SEVERAL DAYS IF THIS SCENARIO PANS OUT.17/28
&&
.AVIATION...VFR FLIGHT CATEGORIES CONTINUE TO PREVAIL AT ALL TAF
SITES THIS AFTERNOON. THIS WILL CONTINUE TO BE THE CASE FOR THE
REMAINDER OF THIS AFTERNOON AND INTO FRIDAY MORNING. THE ONLY
DEGRADATION OF CATEGORIES CONTINUES TO BE THAT OF CONVECTION
OCCURRING ON STATION. OBSERVED CONVECTION WILL BRING ABOUT A BRIEF
PERIOD OF MVFR/IFR VISIBILITIES AND/OR CEILINGS. WIND GUSTS RANGING
FROM 35-52 KNOTS WILL ALSO BE POSSIBLE WITH THE MOST INTENSE
STORMS...ALONG WITH FREQUENT CLOUD TO GROUND LIGHTING STRIKES.
CONVECTION WILL BEGIN TO WANE IN BOTH COVERAGE AND INTENSITY AROUND
00Z THIS EVENING...WITH QUIET CONDITIONS EXPECTED OVERNIGHT. /19/
