EXTENT OF SHOWERS AND THUNDERSTORMS TONIGHT THE CONCERN...BEFORE
TRANSITION TO DRIER AND WARMER WX BEGINS SUNDAY.

CURRENTLY: CONVECTION OFF TO A SLIGHTLY SLOWER START TODAY AS RAIN-
COOLED AIR OVER THE AREA HAS TAKEN TIME TO DESTABILIZE. ELONGATED
UPPER SHEAR AXIS ACROSS ERN CO...WITH WEAK CIRCULATION OVER NERN
CORNER OF CO AND FAIRLY WELL DEFINED UPPER LOW OVER WRN TX/ERN
NM. APPEARS THERE ARE PLENTY OF MESOSCALE BOUNDARIES ACROSS THE
PLAINS TO FOCUS CONVECTION LATER THIS AFTERNOON AS AIR MASS
DESTABILIZES.

TONIGHT...CONTINUED THE BROAD BRUSH OF SCT -TSRA WELL INTO THE
OVERNIGHT HOURS MOST SECTIONS...THOUGH ACTIVITY OVER THE SWRN MTNS
AND VALLEYS SHOULD DIE FAIRLY QUICKLY AFTER SUNSET AS MOISTURE
ISNT QUITE AS DEEP HERE AS FARTHER EAST. HARD TO PIN DOWN WHICH
AREAS OVER THE PLAINS WILL SEE HEAVY RAINFALL...AS MESOSCALE
FEATURES AND OUTFLOW BOUNDARIES WILL ULTIMATELY DETERMINE WHERE
STORMS DEVELOP. VERY SLOW STORM MOTIONS ONCE AGAIN...AND AREAS
THAT RECEIVED HEAVY RAIN LAST NIGHT...I.E. EL PASO/BACA/LAS ANIMAS
COUNTIES NEED TO BE WATCHED.

SUNDAY/SUNDAY NIGHT...UPPER HIGH CONTINUES TO BUILD OVER THE
CENTRAL ROCKIES AS SHEAR AXIS OVER ERN CO WEAKENS AND UPPER LOW
OVER NM SLOWLY FILLS. STILL ENOUGH MOISTURE TO FIRE AFTERNOON AND
EVENING CONVECTION MOST AREAS...THOUGH COVERAGE WILL BE FAIRLY
SPARSE AS MID AND UPPER LEVELS WARM. SUSPECT CONVECTION WILL
QUICKLY END AFTER SUNSET WITH LACK OF UPPER SUPPORT. MAIN CHANGE
TO CURRENT GRIDS WAS TO CUT BACK CONVECTIVE POPS TO LOW CHC/SLIGHT
CHC MANY AREAS. MAX TEMPS BEGIN TO RESPOND TO RISING HEIGHTS...WITH
WARMER FWC NUMBERS MORE REASONABLE.

MONDAY...CONTINUED WARMER AND DRIER...THOUGH AGAIN MOISTURE TRAPPED
UNDER THE RIDGE MAY FIRE A FEW AFTERNOON -TSRA OVER MAINLY
HIGHER TERRAIN. CUT BACK POPS TO SLIGHT CHANCES MOST AREAS...THOUGH
DIDNT ELIMINATE ENTIRELY. WARMED UP MAX TEMP GRIDS SLIGHTLY...IN
LINE WITH GUIDANCE NUMBERS.

TUES-SAT...LARGE UPPER RIDGE TO CONTINUE OVER THE CENTRAL ROCKIES...
WHICH WILL TEND TO SUPPRESS MOST CONVECTION. CONTINUED THE GENERIC
SUMMERTIME FORECAST OF NEAR TO SLIGHTLY ABOVE NORMAL TEMPS AND
ISOLATED AFTERNOON AND EVENING CONVECTION EACH DAY. AVN SHOWS RIDGE
AMPLIFYING ENOUGH TO ALLOW A WEAK FRONT TO DROP SOUTH ALONG THE ERN
PLAINS WED...WHICH MAY SERVE TO INCREASE CONVECTION SOMEWHAT BY
MIDWEEK. DOESNT APPEAR TO BE MUCH COOLING WITH THIS SYSTEM...SO WILL
MAINTAIN WARM TO HOT TEMPS EACH DAY.

.PUB...NONE.
