AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
424 AM CST THU JAN 23 2014

...DANGEROUS WIND CHILL TEMPERATURES TONIGHT...
.SHORT TERM...TODAY THROUGH FRIDAY NIGHT...WATER VAPOR IMAGERY SHOWS
A POTENT NORTHERN STREAM SHORTWAVE DROPPING INTO THE CENTRAL PLAINS
AROUND THE CLOSED LOW NOTED SPINNING OVER THE GREAT LAKES REGION.
THIS SHORTWAVE WILL HELP SEND A 1045MB HIGH SOUTH ACROSS THE
NORTHERN PLAINS THIS MORNING AND OVER THE CENTRAL PLAINS BY THIS
EVENING. IN TURN...AN ARCTIC COLD FRONT NOTED MOVING INTO NORTHWEST
TENNESSEE AND CENTRAL ARKANSAS EARLY THIS MORNING WILL DROP INTO OUR
HIGHWAY 82 CORRIDOR BEFORE NOON AND OVER OUR HIGHWAY 84 CORRIDOR BY
THIS EVENING. VERY COLD AND DRIER AIR(NEGATIVE DEW POINT
TEMPERATURES) WILL MOVE INTO OUR CWA IN THE WAKE OF THE FRONT.
TEMPERATURES WILL HAVE A CHANCE TO WARM AHEAD OF THE FRONT BUT DROP
THROUGH THE AFTERNOON BEHIND THE FRONT. TEMPERATURES OVER PORTIONS
OF THE DELTA REGION WILL TOP OUT BRIEFLY ABOVE FREEZING BEFORE
DROPPING BACK BELOW FREEZING. THIS WILL BEGIN A PROLONGED PERIOD OF
BELOW FREEZING TEMPERATURES FOR OUR NORTHEAST ZONES WHERE A HARD
FREEZE WARNING WILL REMAIN IN AFFECT.  A SOUTHERN STREAM DISTURBANCE
MOVING ACROSS TEXAS TODAY WILL DEVELOP PRECIPITATION TO OUR WEST
THIS AFTERNOON AS THE COLD AIR IS MOVING INTO OUR AREA. THERE WILL
BE A VERY LOW CHANCE OF LIGHT RAIN MIXING WITH LIGHT SLEET AND LIGHT
SNOW LATE THIS AFTERNOON OVER OUR SOUTHWEST LOUISIANA PARISHES AND
SOUTHWEST MISSISSIPPI COUNTIES. THIS ACTIVITY WILL END AS A FEW
FLURRIES EARLY THIS EVENING AS THE CHANCE OF PRECIPITATION SHIFTS
WELL SOUTH OF OUR CWA. TONIGHT THE 1040MB+ HIGH WILL DROP OVER THE
SOUTHERN PLAINS BUT RIDGE EAST ACROSS NORTH MISSISSIPPI. GUSTY NORTH
WINDS THIS AFTERNOON WILL BECOME LIGHTER THROUGH THE NIGHT BUT
REMAIN STRONG ENOUGH TO RESULT IN SINGLE DIGIT WIND CHILL
TEMPERATURES. THESE LOW WIND CHILL VALUES WILL OCCUR OVER THE NORTH
THIS EVENING AND OVER THE SOUTH AFTER MIDNIGHT. A WIND CHILL
ADVISORY HAS BEEN ISSUED FOR THE WHOLE CWA TONIGHT THROUGH 9AM
FRIDAY. A VERY COLD NIGHT IS ON TAP TONIGHT AS SITES IN THE NORTH
BOTTOM OUT 10-12F AND IN THE TEENS ELSEWHERE. FRIDAY THE 1040MB HIGH
WILL SHIFT SOUTH TO THE GULF COAST AND WEAKEN. LIGHT SOUTHWEST FLOW
IS EXPECTED TO DEVELOP DURING THE AFTERNOON AND HELP TEMPERATURES
WARM ABOVE FREEZING AT MOST LOCATIONS. THE EXCEPTION IS EXPECTED TO
BE THE NORTHEAST WHERE THE HARD FREEZE WARNING IS IN EFFECT. ANOTHER
NORTHERN STREAM SHORTWAVE WILL DROP OVER THE PLAINS FRIDAY NIGHT. AN
ASSOCIATED COLD FRONT WILL DROP OVER THE MID MISSISSIPPI VALLEY BY
SUNRISE SATURDAY MORNING. WEAK WAA OVERNIGHT IN OUR AREA WILL HOLD
TEMPERATURES IN THE 20S AT MOST LOCATIONS BUT MORNING LOWS MAY DIP
BACK INTO THE TEENS IN THE NORTHEAST. /22/

.LONG TERM...SATURDAY THROUGH NEXT THURSDAY...AFTER A BRIEF RESPITE
LATER SATURDAY AND DEFINITELY SUNDAY COLD WEATHER LOOKS TO RETURN
(POSSIBLY WITH A VENGEANCE) BY MONDAY NIGHT. THE GENERAL AMPLIFIED
UPPER LEVEL NORTHWEST FLOW PATTERN ACROSS OUR REGION LOOKS TO
RETROGRADE A BIT DURING THE LONG TERM PERIOD. CONDITIONS LATELY HAVE
BEEN VERY DRY AS MOISTURE AND DEEP ATMOSPHERIC LIFT HAVE MAINLY BE
SHUNTED OFF TO OUR EAST AND SOUTHEAST. HOWEVER...WITH THE
RETROGRADING OF THE PATTERN CHANCES OF PRECIPITATION MAY START TO
SUBTLY AND GRADUALLY INCREASE. THAT SAID...CONFIDENCE IN MEASURABLE
PRECIPITATION AT THIS POINT ONLY HIGH ENOUGH TO INCLUDE AN OFFICIAL
MENTION IN THE FORECAST AHEAD OF COLD FRONT SUNDAY NIGHT (AND THEN
ONLY IN SOUTHERN ZONES) AND AGAIN ACROSS ALL AREAS NEXT THURSDAY.

HIGHLIGHTS SATURDAY AND SUNDAY...THE AIR MASS WILL BE MODIFYING IN
FRONT OF ARCTIC SURGE STARTING TO ARRIVE SUNDAY NIGHT. DAYTIME
SATURDAY AND SUNDAY WILL BE DOMINATED BY GENERAL WESTERLY WIND
VECTORS ABOVE THE SURFACE IN A TEMPORARY WARM AIR ADVECTION REGIME.
ALTHOUGH SOME SEMBLANCE OF GULF MOISTURE MAY TRY TO SNEAK NORTH INTO
SOUTHERN ZONES ON SUNDAY...THE AIR MASS SHOULD GENERALLY REMAIN
QUITE DRY...AND COUPLED WITH DRY GROUND...WILL PROMOTE BIG TIME
MIXING. MEXMOS HIGHS RAISED THESE DAYS...BUT ESPECIALLY
SUNDAY...WHEN THE EXPERIENCE OF A FEW SIMILAR SCENARIOS OVER THE
PAST FEW WEEKS MAKES HIGHS IN THE LOW TO MID 60S PLAUSIBLE IN MANY
LOCATIONS.

MONDAY AND TUESDAY...ENERGY DROPPING DOWN THE BACKSIDE OF A
RETROGRADING EASTERN CONUS TROUGH REGIME WILL COMPLETELY OPEN THE
DOOR FOR CONSIDERABLE ARCTIC AIR PUSH DOWN THE AXIS OF THE LOWER MS
VALLEY. OPERATIONAL MODELS HINT THE FULL CHILLING DOWN IN THESE
PARTS MAY COME IN TWO STAGES...SUCH AS AN INITIAL COLD FRONT SUNDAY
NIGHT INTO MONDAY MORNING FOLLOWED BY A REINFORCING COLD FRONT
MONDAY NIGHT. MODELS HINTS AT VERY MINOR PRECIP CHANCES THROUGH THIS
PERIOD...MAINLY DUE TO THE STRENGTH OF UPPER LEVEL TROUGH ENERGY
PASSING OVERHEAD. THIS POTENTIAL WILL HAVE TO BE MONITORED AND IT IS
DEFINITELY NOT OUT OF THE QUESTION SOME AREAS MAY EXPERIENCE SOME
FLURRIES AS THE COLD AIR BUILDS IN. HOWEVER...AT THIS POINT CHANCES
FOR ANY SIGNIFICANT WINTRY TYPE PRECIP ARE WAY TOO LOW TO INCLUDE
MENTION OF IN THE OFFICIAL FORECAST. AT THIS STAGE MEXMOS TEMPS
SURPRISINGLY LOOK REASONABLY FRIGID ENOUGH...ALTHOUGH I DID CUT
HIGHS IN NORTHERN ZONES MONDAY A BIT.

TUESDAY NIGHT AND WEDNESDAY...MODEL CONSENSUS RATHER GOOD THAT
TUESDAY NIGHT WILL BE THE COLDEST NIGHT AS MODIFYING ARCTIC HIGH
PRESSURE CENTER SETTLES DOWN TOWARD THE REGION. RADIATIONAL COOLING
MAY NOT BE PERFECT GIVEN SUCH STRONG HIGH PRESSURE COMING IN BUT IT
SHOULD BE GOOD ENOUGH TO YIELD DECENT CHANCE AT HITTING MEX LOWS WAY
DOWN IN THE TEENS. WEDNESDAY DAYTIME MAY END UP BEING COLDER THAN
THE WIDESPREAD 30S REPRESENTED IN THE CURRENT FORECAST...BUT
POTENTIAL FOR WEAK WARM ADVECTION MAKES IT PRUDENT TO NOT YET CUT
MEX HIGHS TOO AGGRESSIVELY FOR THAT PARTICULAR AFTERNOON.

BY WEDNESDAY NIGHT AND THURSDAY THE CONFIDENCE IN DETAILS DROPS A
BIT...BUT HIGHEST CHANCES ARE FOR GRADUAL AIR MASS MODIFICATION
WHILE AT LEAST LOW END OVERRUNNING-TYPE PRECIP CHANCES MATERIALIZE
AS A DISTURBANCE DROPS DOWN IN FLATTENING NORTHWEST FLOW. SOME
WINTRY PRECIPITATION CAN DEFINITELY NOT BE RULED OUT ON
THURSDAY...ESPECIALLY IN NORTHERN ZONES...BUT POTENTIAL FOR IMPACT
AT THIS JUNCTURE IS TOO LOW TO INCLUDE IN THE HWO.

OTHERWISE...THE HWO WILL BE UPDATED TO REFLECT POTENTIAL FOR SINGLE
DIGIT WIND CHILLS AND POSSIBLE HARD FREEZE IMPACT FOR AT LEAST
NORTHERN ZONES IN THE TUESDAY TO WEDNESDAY TIME FRAME. ALSO WILL
MENTION INCREASED FIRE DANGER SATURDAY THROUGH TUESDAY SINCE
PRECIPITATION CHANCES QUITE MINIMAL AND RH / WIND THRESHOLDS COULD
OCCASIONALLY BE ON THE BORDER OF RED FLAG CRITERIA. /BB/

&&

.AVIATION...VFR CONDITIONS EXPECTED THROUGH FORECAST PERIOD. MAIN
IMPACT TO AVIATION WILL BE INCREASING NORTHERLY WINDS TODAY AS
ARCTIC AIR RUSHES INTO REGION. NORTH WINDS WITH GUSTS OF 20-25KT ARE
LIKELY BY AFTERNOON. HIGH CLOUDS AS NOTED ON SATELLITE IMAGERY EARLY
THIS MORNING WILL THICKEN AND MID CLOUDS WILL INCREASE AS AN UPPER
WAVE APPROACHES FROM THE NORTHWEST. THERE WL BE A VERY LOW CHANCE OF
A FLURRY/SPRINKLE IN THE SW LATE THIS AFTN AND EARLY EVNG BUT WL NOT
AFFECT TAF SITES. /AEG/22/

&&

.FIRE WEATHER...A STRONG DRY COLD FRONT WILL SWEEP ACROSS THE AREA
TODAY AND PRODUCE GUSTY NORTHWEST TO NORTH 20-FOOT WINDS IN EXCESS
OF 15 MPH. RELATIVE HUMIDITIES WILL DROP BELOW CRITICAL VALUES
PRODUCING RED FLAG CRITERIA FOR A COUPLE OF HOURS LATE THIS
AFTERNOON OVER THE NORTH AND CENTRAL DISTRICTS. CONSIDERING THE
BRIEF WINDOW OF MEETING CRITERIA AND WITH TEMPERATURES PLUMMETING
THIS AFTERNOON...LOWERING THE IGNITION COMPONENT OF THE FUELS HAVE
OPTED NOT TO ISSUE A RED FLAG WARNING FOR TODAY. AFTERNOON MINIMUM
RELATIVE HUMIDITIES WILL BE EVEN LOWER FRIDAY AND FOR A LONGER
DURATION BUT 20-FOOT WINDS WILL BE LIGHTER AND RED FLAG CRITERIA IS
NOT EXPECTED TO BE MET. /22/

...HAZARD LEGEND...

*FIRE WEATHER*
EXTREME...VERY STRONG WINDS IN EXCESS OF RED FLAG WARNING
 CONDITIONS COMBINED WITH LIMITED TO MODERATE HUMIDITY. FIRES
 WILL SPREAD QUICKLY AND SPOT FIRES ARE COMMON. FIRE CONTROL IS
 VERY DIFFICULT DUE TO STRONG WINDS.
HIGH...OPEN BURNING SHOULD NOT BE ATTEMPTED. HIGH WINDS AND
 EXTREME DRY PERIODS LEAD TO EXTREME BURNING CONDITIONS. OPEN
 FIRES CAN QUICKLY ESCAPE AND ARE VERY DIFFICULT TO CONTROL,
 EVEN FOR EXPERIENCED FIREFIGHTERS. CONDITIONS CAN MEET
 MINIMUM CONDITIONS FOR RED FLAG WARNINGS IN MOST CASES.
ELEVATED...ANY OPEN BURNING IS DISCOURAGED DUE TO INCREASED
 WIND AND LOWER HUMIDITY, EXCEPT BY EXPERIENCED FIRE
 PERSONNEL. INCREASING WINDS AND LOWER HUMIDITY CONTRIBUTE TO
 DRYING FUELS. FIRES ESCAPE CONTROL MORE EASILY AND
 CONTAINMENT IS DIFFICULT FOR INEXPERIENCED FIRE PERSONNEL.
 APPROACHING RED FLAG CONDITIONS.
LIMITED...OPEN BURNING IS USUALLY SAFE WITH PROPER CONTAINERS
 AND PRECAUTIONS UNDER LIMITED FIRE DANGER CONDITIONS.
