.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 116 PM MDT TUE MAY 21 2013

NORTHWEST FLOW WILL BE OVER THE CENTRAL PLAINS TONIGHT AND WEDNESDAY
WITH A RIDGE OVER THE ROCKIES. SURFACE HIGH PRESSURE WILL CONTINUE
TO BUILD SOUTH INTO THE PLAINS TONIGHT AND WEDNESDAY.

SUBSIDENCE AND LACK OF MOISTURE SUPPORT NIL POPS FOR TONIGHT AND
WEDNESDAY AS THE UPPER LOW SHIFTS FURTHER EAST INTO THE MISSISSIPPI
RIVER VALLEY. WINDS WILL GRADUALLY BECOME LIGHT OVERNIGHT AS THE
ATMOSPHERE DECOUPLES. WINDS WILL REMAIN LIGHT ON WEDNESDAY AS THE
UPPER LOW MOVES FURTHER AWAY AND THE SURFACE GRADIENT RELAXES.

MIN TEMPERATURES TONIGHT WILL COOL TO THE 40S. MAX TEMPERATURES
WEDNESDAY WILL RISE INTO THE LOWER/MID 70S WITH A FEW UPPER 70S IN
THE SOUTHERN FA.

.LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY)
ISSUED AT 110 PM MDT TUE MAY 21 2013

WEDNESDAY NIGHT THROUGH FRIDAY...STILL HAVE A BIT OF CONCERN FOR
SOME ISOLATED SHOWERS/THUNDERSTORMS WEDNESDAY NIGHT AS A WEATHER
DISTURBANCE TO THE WEST OF THE AREA DURING THE DAY SLIDES EAST
ACROSS THE FORECAST AREA OVERNIGHT. NOSE OF LOW LEVEL JET
STRENGTHENS OVER THE AREA WHICH MAY PROVIDE ENOUGH SUPPORT AND
NEGATE THE LACK OF MOISTURE BELOW 700MB. FOR NOW WILL MAINTAIN
SILENT POPS. ON THURSDAY LOW LEVEL MOISTURE INCREASES ACROSS THE
AREA PRODUCING A RATHER CLOUDY DAY. NO MOISTURE ABOVE 700MB AND NO
INSTABILITY TO SPEAK OF. MID LEVEL LAPSE RATES MAY BE ENOUGH TO
PRODUCE A FEW STABLE SHOWERS OR MAYBE SOME DRIZZLE. HAVE INCREASED
POPS A BIT FOR SOME RAIN SHOWERS. FOR THURSDAY NIGHT PRECIPITATION
CHANCES INCREASE QUITE RAPIDLY AFTER MIDNIGHT AS A WEATHER
DISTURBANCE MOVES IN FROM THE SOUTHWEST. CURRENT POPS LOOK GOOD WITH
HIGHEST CHANCES GENERALLY EAST OF THE CO/KS BORDER. AS THIS SYSTEM
EXITS THE AREA DURING THE MORNING FRIDAY WE SHOULD SEE A LULL TIL
LATE AFTERNOON WHEN A FEW THUNDERSTORMS ARE POSSIBLE ACROSS THE WEST
OR SOUTHWEST PORTION OF THE AREA AS MOISTURE MOVES IN FROM THE
SOUTHWEST.

HIGHS THURSDAY GENERALLY IN THE 60S WITH PERHAPS A FEW 70S ACROSS
THE FAR EAST/NORTHEAST. WARMER FRIDAY WITH MID TO UPPER 70S
EAST...LOW TO MID 80S WEST. LOWS IN THE 40S WEDNESDAY NIGHT...50S
THURSDAY NIGHT.

FRIDAY NIGHT-TUESDAY...FORECAST AREA TO REMAIN IN SOUTHWEST FLOW
ALOFT AS LOW PRESSURE REMAINS ACROSS THE WEST/NORTHWEST AND HIGH
PRESSURE HOLDS ACROSS PARTS OF TEXAS. WILL CONTINUE WITH DAILY
CHANCES OF SHOWERS AND THUNDERSTORMS AS MONSOONAL TYPE PATTERN SETS
UP. HIGHS THROUGH THE PERIOD IN THE 80S WITH LOWS IN THE 50S AND
60S.

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z WEDNESDAY NIGHT)
ISSUED AT 1106 PM MDT TUE MAY 21 2013

IN THE WAKE OF THE EXITING LOW PRESSURE SYSTEM...HIGH PRESSURE AT
THE SURFACE BEGINS TO MOVE INTO THE CENTRAL HIGH PLAINS REGION
FROM THE NORTHERN PLAINS WHILE THE RIDGE AXIS ALOFT MOVES FROM THE
ROCKIES TO THE HIGH PLAINS. MID TO HIGH CLOUDS SHOULD DIMINISH
THROUGH THE OVERNIGHT HOURS AND DURING THEY DAY ON WEDNESDAY AS A
RESULT. HOWEVER...WITH THE RETURN FLOW AROUND THE SURFACE HIGH
PRESSURE AREA PRODUCING UPSLOPE FLOW ACROSS THE REGION LATE IN THE
TAF PERIOD WEDNESDAY EVENING...THERE IS THE POSSIBILITY OF LOW
CLOUDS AND SOME AREAS OF REDUCED VISIBILITY DEVELOPING IN THE LOW
LEVEL EASTERLY FLOW.
