MORNING WILL BECOME SLIGHTLY BREEZY BY THE AFTN HOURS /15-17 KTS/.
SCATTERED LIGHT SHOWERS HAVE SHIFTED TO NEAR KCDS...ALTHOUGH
LATEST RADAR SIGNATURE INDICATED A WANING TREND.
HOWEVER...ADDITIONAL DEVELOPMENT HAS OCCURRED WELL SOUTH OF KCDS
AND WILL THEREFORE MAINTAIN A VCSH MENTION FOR KCDS THROUGHOUT THE
AFTN ATTM...AND WILL AMEND AS NECESSARY. THIS EVENING...PRECIP
WILL SHIFT EAST OF KCDS AND SRLY WINDS WILL DECLINE A BIT TO AOA
10 KTS.

.PREV DISCUSSION... /ISSUED 240 AM CDT SAT JUN 15 2013/ 

SHORT TERM...
SCATTERED LIGHT SHOWERS PERSISTED ACROSS PORTIONS OF THE SERN TX 
PANHANDLE....ROLLING PLAINS AND CENTRAL SOUTH PLAINS EARLY THIS 
MORNING...WITH A SLOW MOVEMENT TO THE NNE. THIS PRECIP ACTIVITY IS 
OF COURSE COURTESY OF THE UA WEAKNESS THAT HAS TREKKED NNE ACROSS 
THE PANHANDLES...THUS NEARING THE CENTRAL PLAINS. IT IS INTERESTING 
TO NOTE THAT A LINE OF SHOWERS AND THUNDERSTORMS THAT HAVE DEVELOPED 
ACROSS THE HIGHER TERRAIN OF EASTERN NEW MEXICO LAST NIGHT...HAVE 
TRANSLATED SSE FROM THE WRN AND SWRN ZONES TO ACROSS THE PERMIAN 
BASIN. THIS LINE WAS CHARACTERIZED BY EMBEDDED HEAVIER ECHOES AS 
NOTED BY THE TEXAS TECH MESONET SITES A FEW HOURS AGO AT DORA NEW 
MEXICO AND MORTON /A QUICK THREE-TENTHS OF AN INCH WITHIN ONE HOUR/. 
HOWEVER...THIS LINE HAS SINCE LOST ITS STRENGTH AND LINEARITY LOOK.

MODEL SOLUTIONS DISPLAY THE UA WEAKNESS MOVING NE ACROSS THE CENTRAL 
PLAINS TODAY THUS SHIFTING LINGERING RAIN CHANCES TO THE ROLLING 
PLAINS THROUGHOUT THE MORNING HOURS...TO FINALLY EAST OF THE FA BY 
16/00Z. RAINFALL AMOUNTS ARE PROGGED TO BE LIGHT IN GENERALLY BUT 
WITH THE POTENTIAL FOR LOCALLY HIGHER AMOUNTS /A FEW TENTHS OF AN 
INCH/ IF TRAINING OCCURS. AS THE WEAKNESS CONTINUES TO EXIT THE 
REGION...UA RIDGING WILL COMMENCE TO AMPLIFY ACROSS THE DESERT 
SW...WITH THE CENTER NOTED ACROSS NERN OLD MEXICO. AS 
SUCH...INCREASING HEIGHT FIELDS SUGGESTS A WARMER DAY /UPPER 80S TO 
LOWER 90S/. IT IS INTERESTING TO NOTE THAT MOIST CONDITIONS WILL 
ENSUE ACROSS THE SOUTHERN PLAINS TODAY /DEWPOINTS IN THE 50S AND 
60S/...AND THEREFORE IT IS NO SURPRISE TO SEE THAT THE DRYLINE WILL 
BE LOCATED ACROSS CENTRAL/EASTERN NEW MEXICO. WITH FORECAST 
SOLUTIONS DISPLAYING AN EMBEDDED IMPULSE ROUNDING THE NORTHERN 
PERIPHERY OF THE SAID CENTER OF THE RIDGE...COMBINED WITH A LOW 
LEVEL FOCUS PROVIDED BY THE DRYLINE /AND A NEARBY SFC TROUGH/...WILL 
CAUSE THUNDERSTORMS TO DEVELOP ACROSS THE HIGHER TERRAIN OF EASTERN 
NEW MEXICO LATE THIS AFTN. THIS IS OF IMPORTANCE TO US BECAUSE 
ADEQUATE WSW FLOW ALOFT WILL ALLOW THESE STORMS TO NEAR/MOVE ACROSS 
THE FAR SWRN TEXAS PANHANDLE TOWARDS THE END OF THE SHORT TERM 
PERIOD. THIS SEEMS REASONABLE AND HAVE GONE AHEAD AND INSERTED 
MENTIONABLE POPS ACROSS THE FAR NW ZONES TONIGHT.

LONG TERM...
POTENTIALLY ACTIVE WEATHER THE FIRST HALF OF THE LONG TERM PERIOD.
A FLAT UPPER RIDGE SUNDAY MAY ALLOW HIGH TERRAIN STORMS TO MOVE
INTO THE FCST AREA SUNDAY NIGHT. MONDAY WILL SEE A COLD FRONT MOVE
INTO THE AREA WHICH IS EXPECTED TO SERVE AS THE FOCUS FOR
THUNDERSTORM DEVELOPMENT MONDAY AFTERNOON AND EVENING. WHILE THE
FRONT IS EXPECTED TO UNDERGO FRONTOLYSIS TUESDAY...LOW LEVEL FLOW
SHOULD REMAIN BACKED TO THE SE AND REMAIN FAIRLY MOIST. AT THE
VERY LEAST SHOULD SEE POTENTIAL AGAIN FOR PRECIP TO MOVE OFF THE
HIGH TERRAIN OF ERN NM. CHC POPS FOR EACH OF THOSE SCENARIOS IS
WARRANTED. 

CHANGE COMES MIDWEEK WHEN AN UPPER LEVEL TROUGH MOVES ONTO THE
WEST COAST. THIS WILL SHIFT THE UPPER RIDGE JUST ENOUGH TO THE
EAST TO ALLOW UPPER FLOW TO BACK TO THE SW FROM THE FOUR CORNERS
TO THE CNTL PLAINS RESULTING IN LESS FAVORABLE CONDITIONS FOR
STORM DEVELOPMENT IN NM AND EVEN LESS FAVORABLE TOWARD MOVING
THOSE STORMS THAT DO FORM INTO THE FCST AREA. AS A RESULT KEEPING
POPS BELOW MENTION IN THE WEDNESDAY THRU FRIDAY TIME FRAME LOOKS
APPROPRIATE. TEMPS LIKELY TO WARM INTO THE MIDDLE TO UPPER 90S
UNDER THIS REGIME.
