542 PM MDT SUN AUG 3 2008
.DISCUSSION...
THE ONGOING EXCESSIVE HEAT WILL PERSIST FOR ONE MORE DAY BEFORE A
SLOW DOWNWARD TREND TAKES PLACE ACROSS THE CWA.
AT PRESENT A SFC TROUGH OF LOW PRESSURE DRAPED ACROSS THE WRN
QUAD OF THE CWA MAY ALLOW FOR AN ISOLATED STORM OR TWO TO DEVELOP
LATE THIS AFTERNOON INTO EARLY EVENING. HAVE INTRODUCED LOW POPS
FOR THE CO CNTIES AND FAR WRN SE NE. FOR TOMORROW, I HOISTED A
HEAT ADVIS FOR THE SAME LOCATIONS AS TODAYS HEAT ADVISORY, BASED
ON PROGGED HEAT INDICES NEAR THE 105F MARK. THERE IS AN
OPPORTUNITY FOR STORMS TOMORROW AFTERNOON AND EVENING WITH THE
APPROACH OF A COLD FRONT... MAINLY NORTH OF THE I-70 CORRIDOR.
TEMPS ON TUE ARE A BIT PROBLEMATIC DUE TO THE POSITION OF THE COLD
FRONT ACROSS THE CWA. THE VARIOUS NWP OFFER SCATTERED SOLUTIONS ON
FRONTAL POSITIONING. FOR THE MOMENT, THE FCST CALLS FOR THE FRONT
TO LIE SOUTH OF I-70 COME TUE AFTERNOON, AND THUS, THE WARMEST
TEMPS WILL BE REALIZED ALONG THE DDC/GLD CWA BORDER 90S SOUTH,
UPR 80S NORTH.
FOR THE REST OF THE FSCT PERIOD, A SERIES OF S/WV TROUGHS WILL
GLANCE THE REGION, THE DEEPEST OF WHICH APPEARS TO MOVE THROUGH
THUR NIGHT. GIVEN THE RESIDUAL FRONTAL BNDRY/BAROCLINIC ZONE IS
PROGGED TO PERSIST ACROSS THE AREA AND THE UPPER LEVEL SUPPORT,
THERE ARE LOW CHANCE POPS FOR TSRA EACH AFTERNOON EVENING. IT
SHOULD BE NOTED THAT NONE OF THE NWP SOLUTIONS DEPICT ANYTHING
WIDESPREAD IN TERMS OF AREAL COVERAGE.
