240 PM MDT SUN JUL 8 2001

AS YET STORMS ON 88D BEHAVING THEMSELVES...BUT BEST DYNAMICS IS
YET TO COME. 18 UTC/NOON MESO-ETA LOOKED VERY GOOD WITH VORTICITY
LOBE FROM RIW AREA TO SOUTHWEST CORNER OF WY...TRIGGERING STORMS THAT
AREA. LOBE EXTENDED EAST-SOUTHEASTWARD...POSSIBLY TRIGGERING
STORMS OVER NORTH LARAMIE RANGE. ALSO DISTURBANCE OVER CENTRAL CO.
MESO-ETA AT 21 UTC HAS 350+K THETA-E AXIS EXTENDING NORTHWEST/
SOUTHEAST FROM CYS WITH WEAKER LOBE NORTHWARD INTO GCC AREA. STORMS
SO FAR DEFINITELY MULTI-CELLULAR. APPEARS TRIGGER FOR THIS ROUND
WILL MOVE EAST OF CWA AROUND 06 UTC/MIDNIGHT. 18 UTC MESO-ETA
CONTINUES IDEA OF ANOTHER STRENGTHENING CENTER APPROACHING WY/CO
BORDER SOUTH OF LAR AT 12 UTC. FEATURE DOESN/T LIFT NORTH OF CWA
UNTIL 00 UTC...SO WILL NEED POSSIBILITY LATE NIGHT/MORNING SHOWERS
PLUS THREAT ISOLATED T-STORMS...DESPITE LACK OF QPF ON MESO-ETA FOR
THOSE TIME PERIODS. MODELS CONTINUE IDEA OF LONG/WAVE TROUGH/500 MB
LOW MOVING INTO GREAT BASIN/MONTANA LATER PERIODS...WHICH AT LEAST
WILL ALTER PATTERN SOMEWHAT.  WILL GO WITH LIKELY POPS THROUGH
MONDAY EVENING...THEN SCATTERED TYPE ONES.  TEMPS GUIDANCE GETTING
MORE IN SYNC...ONLY A HAIR TOO COOL WITH MAXS/MINS.

.EXTENDED DISCUSSION...
STRONG UPPER RIDGE WILL CONTINUE OVER THE AREA WITH THE CENTER OF
THE HIGH OVER NORTHERN TEXAS.  THE HIGH PRESSURE CENTER RETROGRADES
INTO THE DESERT SOUTHWEST THROUGH THE PERIOD...LEAVING THE CWA IN SW
FLOW ALOFT.   SEVERAL SHORT-WAVES WILL MOVE AROUND THE HIGH
PRESSURE AND ACROSS THE FORECAST AREA THROUGH THE PERIOD.  THIS
COMBINED WITH MONSOONAL MOISTURE WILL KEEP THE CWA IN A CHANCE
OF DAILY THUNDERSTORMS.  STILL NO MAJOR FRONTS ON THE HORIZON...SO
PERSISTENCE RULES IN TEMPERATURE FORECAST.
