.AVIATION...06Z KGRI TAF. IFR CONDITIONS TO CONTINUE AT THE
TERMINAL BEFORE VFR CONDITIONS ARE RESTORED BY 15Z. SHOWER AND
THUNDERSTORM ACTIVITY WILL HAVE THE POTENTIAL TO IMPACT THE
TERMINAL 07Z THROUGH 11Z. CEILINGS NEAR 800FT AGL WILL REMAIN
POSSIBLE UNTIL 15Z...AT WHICH TIME STRATUS SHOULD GIVE WAY TO MID
AND HIGH LEVEL CLOUDS THROUGH THE REMAINDER OF THE TAF PERIOD.
MINIMAL VISIBILITY RESTRICTIONS IN LIGHT PRECIPITATION WILL BE
POSSIBLE 07Z THROUGH 11Z.

&&

.PREV DISCUSSION... /ISSUED 342 PM CDT THU APR 12 2012/

SHORT TERM...00Z TONIGHT THROUGH 00Z SATURDAY. PRIMARY CONCERN IN
THE SHORT TERM WILL BE THE ONSET OF THE NEXT ROUND OF RAIN/TSTMS
THIS EVENING OR TONIGHT.

WATER VAPOR IMAGERY...ALONG WITH UPPER AIR AND WIND PROFILER DATA
NOTE THE UPPER RIDGE HAS SHIFTED OVER THE MO RIVER VALLEY AS BROAD
UPPER TROUGH MOVES INTO THE WESTERN U.S. DECENT SUBTROPICAL TAP OF
MOISTURE ALSO NOTED WHICH HAS CONTRIBUTED THE THE WIDESPREAD LIGHT
RAIN ACROSS THE CWA THIS MORNING.  VARIOUS WAVES ROTATING AROUND THE
WEST COAST TROUGH WITH THE NEXT ONE NOTED ON SATELLITE PUSHING
THROUGH AZ EARLIER THIS MORNING AND WILL INFLUENCE OUR WEATHER
TONIGHT. AT THE SURFACE...LEE TOUGHING NOTED FROM MT INTO EASTERN
NMEX WITH A TIGHTENING PRESSURE GRADIENT OF 16 MB ACROSS NEB.
DEWPOINTS HAVE RISEN FROM THE LOWER 20S AT NOON YESTERDAY TO MID
40S/LOWER 50S AT THAT TIME TODAY.  AREA OF SHOWERS AND A FEW TSTMS
HAS BEEN SLOW TO CLEAR THE CWA WITH SOME REDEVELOPMENT IN THE WEST
DURING THE LATE MORNING. THIS ACTIVITY HAS FINALLY MOVED EAST OF THE
HIGHWAY 281 CORRIDOR AS OF 1430 LOCAL TIME.

WAVE NOTED ABOVE WILL PUSH THROUGH THE AREA TONIGHT PROVIDING BROAD
SCALE LIFT AND DECENT CHANCE OF SHOWERS AND THUNDERSTORMS
OVERNIGHT.  QUESTION OF SEVERE CHANCES STILL LOOM IN THE SOUTHWEST
PORTION OF THE CWA. MOST OF OUR AREA HAS BEEN SOCKED IN WITH LOW
CLOUDS ALL DAY AND TEMPS HAVE STRUGGLED INTO THE LOW/MID 50S BY 2 PM
LOCAL TIME. THERE HAS BEEN CLEARING IN WESTERN KANSAS WHICH IS WHERE
THE BEST INSTABILITY IS...WHILE WE REMAIN FAIRLY STABLE. MODELS DO
SHOW THE HIGHER INSTABILITY CREEPING INTO THE WEST AND SOUTHWEST
PARTS OF THE CWA THIS EVENING. THE DEEP LAYER SHEAR LOOKS GOOD OVER
THE REGION WITH 0-6 KM SHEAR RANGING FROM 40 TO 60 KT. THERE IS AT
LEAST A THREAT OF SEVERE ESPECIALLY IN THE SOUTHWEST BUT WE COULD
SEE SOME HAILERS FURTHER NORTHEAST INTO NEB OVERNIGHT AS THE
INSTABILITY AXIS SHIFTS THROUGH THE CWA.

THE UPPER WAVE WILL DRAG A SURFACE FRONT THROUGH THE CWA FRIDAY
MORNING WHICH SHOULD DRY THINGS OUT FOR THE DAYTIME AS WINDS SHIFT
TO THE WSW. ALSO EXPECT PARTLY SUNNY SKIES AND TEMPS ON FRIDAY
SHOULD REBOUND INTO THE MID 70S.

LONG TERM...FRIDAY NIGHT THROUGH THURSDAY. IN THE BIG PICTURE A
MID LEVEL LONG WAVE TROUGH WILL GRADUALLY WORK ACROSS THE AREA
THROUGH THE WEEKEND...THEN RIDGING MOVES IN. SO...IT LOOKS UNSETTLED
THROUGH SUNDAY NIGHT...THEN HIGH PRESSURE WILL TAKE OVER.

FRIDAY NIGHT THROUGH SUNDAY NIGHT A SERIES OF SHORT WAVES WILL
MOVE ACROSS THE AREA. IT SHOULD BE DRU FRIDAY EVENING...THEN A
CHANCE FOR THUNDER AFTER MIDNIGHT AS A SHORT WAVE BEGINS TO MOVE
INTO THE AREA. THE LOW LEVEL JET SHOULD PUMP MOISTURE AND MILDER
AIR OVER THE AREA...THUS INSTABILITY AND SHEAR ON THE INCREASE.
HARD TO RULE OUT SEVERE WEATHER DURING THAT TIME...BUT WILL NEED
TO CONTINUE TO MONITOR AS WE GET CLOSER IN TIME.

A SURFACE LOW PRESSURE AREA AND ASSOCIATED BOUNDARY WILL BE MOVING INTO
THE AREA THROUGH SUNDAY. WE WILL BE IN THE WARM SECTOR ON FRIDAY
AND SATURDAY...SO TEMPS IN THE 70S RETURN FOR A FEW DAYS. BEST
CHANCES OF RAIN WILL BE ON THE NORTHERN AND EASTERN PERIPHERIES OF
THE AREA. NOT EXPECTING THE AREA TO BE IN RAIN THE WHOLE
TIME...WILL BE HIT AND MISS RAIN AND PROBABLY DIURNALLY DRIVEN
MUCH OF THE TIME. AS MENTIONED ABOVE...BEING IN THE WARM SECTOR
SHOULD SEE ELEVATED INSTABILITY AND MOISTURE AVAILABILITY THROUGH
THE PERIOD.

THE SYSTEM SHOULD MOVE THROUGH AND EXIT THE AREA ON SUNDAY NIGHT.

COOL/COLD HIGH PRESSURE THEN FORECAST TO BUILD OVER THE AREA
MONDAY THROUGH TUESDAY NIGHT. NEAR OR BELOW FREEZING TEMPS
EXPECTED DURING THE MONDAY NIGHT-TUESDAY MORNING TIME PERIOD. TOO
EARLY TO BE THINKING ABOUT A FREEZE WATCH YET...BUT
AGAIN...SOMETHING TO KEEP OUR EYE ON.

RETURN FLOW BEGINS ON WEDNESDAY AND 70S EXPECTED AGAIN ON
THURSDAY.
