.DISCUSSION...
135 PM MDT TUE JUN 9 2009

SOUTHWEST MID/UPPER FLOW CONTINUES ACROSS THE CENTRAL HIGH PLAINS
WITH A MEAN TROUGH OVER THE SOUTHWEST AND THE SUBTROPICAL RIDGE
CONTINUES TO RESIDE OVER THE MEXICO/WESTERN GULF AREA. H7 WAA
PATTERN SHOULD HELP MAINTAIN ANY LATE AFTERNOON TSRA THAT DEVELOPS
OVER MUCH OF THE FORECAST AREA WEIGHTED ACROSS THE NORTH THROUGH
07-09Z BEFORE ACTIVITY MOVES EAST OF THE AREA. SHEAR/CAPE PROFILES
SUPPORT SEVERE WORDING IN THE ZONES THROUGH THE EVENING.

EXPECT A PERIOD OF SUBSIDENCE EARLY WEDNESDAY BEFORE LARGE-SCALE
FORCING FOR ASCENT INCREASES DOWNSTREAM OF THE NEXT SHORTWAVE TROUGH
LIFTING INTO THE PLAINS STATES LATE IN THE PERIOD. A POST-FRONTAL
REGIME WILL CONTINUE ACROSS THE CENTRAL HIGH PLAINS WITH LIMITED
INSOLATION KEEPING HIGHS FROM REACHING THE 70S IN SOME LOCATIONS.
MAINTAINED MID POPS THROUGH THE AFTERNOON AND EARLY EVENING ACROSS
MUCH OF THE AREA BEFORE LARGE SCALE FORCING FOR SUBSIDENCE DEVELOPS
ACROSS THE AREA.

THU-FRI...WEST-SOUTHWEST MID/UPPER FLOW CONTINUES ACROSS THE CENTRAL
HIGH PLAINS AS A SHORTWAVE RIDGE BUILDS INTO THE ROCKIES.
UNCERTAINTY IN TIMING/PLACEMENT OF DEEP MOIST CONVECTION REMAINS
HIGH AND WILL GENERALLY FOLLOW THE PREVIOUS THEME WITH LOW
PROBABILITIES OF WIDELY SCATTERED DIURNALLY DRIVEN THUNDERSTORMS.
RISING HEIGHTS/THICKNESS SUPPORT A SUBTLE WARMING TREND WITH MAXIMUM
TEMPERATURES REACHING THE LOWER 80S BY FRI.

DAYS 4 THROUGH 7...TYPICAL PHASE AND AMPLITUDE DIFFERENCES ARISE
WITH HANDLING OF MID/UPPER RIDGE AT THE START OF THE PERIOD. WILL
LEAN AWAY FROM THE MORE AMPLIFIED EC WHICH IS NOT SUPPORTED BY
THE EC ENS MEAN AND IS MORE IN LINE WITH THE NCEP ENS MEAN BUT ONLY
SLIGHTLY MORE PROGRESSIVE WITH H5 HEIGHTS ACROSS THE CENTRAL HIGH
PLAINS. THE GENERAL TREND IS A SUBTLE RISE IN HEIGHTS/THICKNESS WITH
SOME WARMING ANTICIPATED EARLY IN THE PERIOD. THERE IS DECENT
AGREEMENT BETWEEN THE GFS/EC HOLDING A TROUGH IN THE SOUTHWEST
THROUGH EARLY NEXT WEEK KEEPING SOUTHWEST MID/UPPER FLOW/LOW
PROBABILITIES FOR DIURNAL THUNDERSTORM ACTIVITY.
