AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
939 PM CST THU FEB 2 2012

.UPDATE...
LATEST RADAR TRENDS DISPLAYED A STRONG LINE OF STORMS THAT HAVE
DEVELOPED ACROSS THE NORTHWESTERN SOUTH PLAINS...COINCIDING WITH A
DRYLINE TYPE FEATURE. THUS...HAVE ADDED PARMER...CASTRO...BAILEY
AND LAMB COUNTIES TO THE SEVERE THUNDERSTORM WATCH IN EFFECT UNTIL
3 AM CST. FURTHERMORE...HAVE UPDATED THE GRIDS TO INCLUDE A SEVERE
MENTION FOR THE AFOREMENTIONED COUNTIES AS HAIL AND GUSTY WINDS
WILL BE POSSIBLE. FARTHER EAST WHERE EARLIER CONVECTION APPEARED
TO HAVE BEEN INTENSIFYING HAVE DIMINISHED. HOWEVER...THE LOW LEVEL
JET IS ANTICIPATED TO INCREASE WITHIN THE NEXT FEW HOURS AND AS
SUCH...CAN NOT RULE RE-DEVELOPMENT.

PREV DISCUSSION... /ISSUED 157 PM CST THU FEB 2 2012/

SHORT TERM...
BEGINNING TO SEE LIFT INCREASE ACROSS THE PANHANDLE EAST OF THE
SLOWLY MOVING UPPER LEVEL LOW CENTERED JUST EAST OF THE 4-CORNERS
WITH INCREASING SHOWER ACTIVITY ACROSS THE AMA FCST AREA. WITH THE
SLOW MOVEMENT OF THE UPPER LOW WOULD EXPECT THIS LIFT TO CONTINUE TO
WORK ON THE NERN THIRD OF THE FCST AREA INTO THE EVENING HOURS. SOME
SVR POTENTIAL STILL EXISTS AS RECENT SFC ANALYSES INDICATE
STRENGTHENING WARM AND MOIST ADVECTION INTO THAT AREA. WILL MAINTAIN
HIGHEST POPS /IN THE LIKELY AND LOW END CATEGORICAL RANGE/ THERE
TAPERING BACK TO SLIGHT CHANCE ACROSS THE SW. WILL THEN AWAIT NEXT
PIECE OF ENERGY THAT IS PROGGED TO BE FURTHER SOUTH IN ASSOCIATION
WITH A MID LEVEL JET STREAK AND VORT MAX THAT WILL ROTATE AROUND THE
BASE OF THE UPPER LOW. LIFT FROM THAT FEATURE IS EXPECTED TO
INITIATE CONVECTION TOWARD 06Z MAINLY IN MOIST AIR EAST OF DRYLINE
AND GENERALLY EAST OF A SILVERTON TO BROWNFIELD LINE. WILL MAINTAIN
LIKELY POPS IN THIS AREA EVEN PULLING THEM A LITTLE BIT FURTHER WEST
WITH 12Z RUNS SUGGESTING THE MOIST AIR NOT BEING AS EASILY DISPLACED.

AS FOR FRIDAY...MODELS SEEM A BIT SLOW IN SHIFTING PRECIP AND LOW
LEVEL MOISTURE EWD. HOWEVER...WOULD STILL EXPECT PRECIP MAY VERY
WELL LINGER ACROSS THE EXTREME ERN PART OF THE FCST AREA PAST 12Z
BEFORE COMING TO AN END BY 18Z. COLD FRONT TO SWEEP ACROSS THE AREA
DURING THE AFTN BUT MAYBE A BIT SLOWER THAN EXPECTED. MOS RESPONDS
WITH TEMPS ABOUT FIVE DEGREES HIGHER THAN PREVIOUS AND HAVE TWEAKED
FCST HIGHS THAT DIRECTION AS A RESULT.

LONG TERM...
FAIRLY QUIET WEATHER IN THE LONG TERM ALTHOUGH DEFINITELY NOT NIL.
UPPER LOW WILL BRING ROUND OF CONVECTION TONIGHT WILL ELONGATE WITH
LOWEST HEIGHT FIELDS ALONG THE KS/CO BORDER AND EXTENDING BACK
TOWARD THE GRAND CANYON.  AS THE CORE SLOWLY DRIFTS EAST...MAKING
INTO THE MID MISSISSIPPI VALLEY BY SUNDAY...WE'LL SEE A THE WESTERN
FRINGES DEEPEN OUT NEAR THE GREAT SALT LAKE AND REMAIN QUITE STAGNANT
EDGING EASTWARD AND FILLING OVER THE WESTERN DAKOTAS BY LATE
TUESDAY.  ANOTHER LOW WILL DIVE ALONG THE PACIFIC COAST AND CUT OFF
ACROSS NRN BAJA BY MID WEEK.

AT THE SURFACE...COLD FRONT WILL SURGE INTO THE AREA FROM EASTERN
COLORADO FRIDAY EVENING AND KEEP WINDS UP IN THE 15 TO 25 MPH RANGE
OVERNIGHT...PERHAPS WANING A BIT TOWARD SUNRISE...THEN BACK UP TO
NEAR 20 MPH OR SO SATURDAY AFTERNOON WHERE WE MAY SEE SOME POST
FRONTAL CUMULUS IMPINGE ON THE NORTHWEST AND NORTHERN ZONES UNDER AN
EXPANSE OF INCREASING HIGH CLOUDINESS.  HIGH PRESSURE SETTLES INTO
THE REGION ON SUNDAY WITH CONTINUED CLOUDINESS AND MUCH LIGHTER
WIND SPEEDS.  THE START OF THE WORK WEEK WITH SEE A RETURN TO
SOUTHWESTERLY FLOW WITH PERHAPS SOME CHANCE AT SOME SHOWER ACTIVITY
BY TUESDAY OR WEDNESDAY WITH INCREASING LOW LEVEL MOISTURE ADVECTION
THOUGH CONFIDENCE IS NOT YET SUFFICIENT TO INCLUDE MENTION ATTM IN
THE GRIDS.
