TODAY'S WEATHER WILL BE SIMILAR TO YESTERDAY'S. MONSOONAL MOISTURE
WILL CONTINUE TO STREAM INTO THE AREA AS THE UPPER LEVEL HIGH SITS
TO OUR SOUTHEAST AND TROUGHING SITS OVER THE WEST COAST. PWS WILL
CONTINUE TO BE IN THE 120% TO 200% OF NORMAL RANGE TODAY. A WEAK
DISTURBANCE IN THE FLOW ALOFT THIS AFTERNOON, UPSLOPE FLOW, AND
THE HIGH PWS WILL LEAD TO ANOTHER DAY OF SCATTERED TO NUMEROUS
STORMS. STORMS ARE EXPECTED TO DEVELOP IN THE AFTERNOON IN AND
AROUND THE HIGHER TERRAIN/FOOTHILLS, MOVING EAST/NORTHEAST INTO
THE LATE EVENING. STORM MOTION WILL BE A BIT FASTER THIS AFTERNOON
COMPARED TO YESTERDAY, WHICH WILL HELP LOWER THE FLASH FLOODING
THREAT. HOWEVER, THE AREAS WHICH HAVE RECEIVED RAIN OVER THE PAST
2 DAYS WILL BE MORE PRONE TO FLOODING, DUE TO MORE SATURATED
SOILS. INSTABILITY AND SHEAR WILL BE A BIT HIGHER THIS AFTERNOON
FOR OUR EASTERN PLAINS. THIS COULD ALLOW FOR A FEW STRONG TO
SEVERE STORMS, WITH POTENTIAL FOR MARGINALLY SEVERE HAIL AND
STRONG WINDS. CAMS ARE LESS ENTHUSIASTIC WITH THE RAIN TOTALS FOR
TODAY COMPARED TO YESTERDAY. THIS, COMBINED WITH THE FASTER STORM
MOTIONS, HAS CAUSED US TO HOLD OFF ON A FLOOD WATCH FOR THIS
AFTERNOON. HOWEVER, HEAVY RAINFALL AND LOCALIZED FLASH FLOODING
IS STILL A THREAT TODAY, ESPECIALLY FOR AREAS THAT RECEIVED HEAVY
RAINFALL THURSDAY.
UPPER LEVEL SOUTHWEST FLOW WILL ALLOW THE MONSOON MOISTURE TO REMAIN
IN THE AREA THROUGH THE WEEKEND. THIS WILL BRING DAILY RAIN CHANCES
FOR OUR FORECAST AREA THROUGH SUNDAY. INSTABILITY AND SHEAR WILL
REMAIN HIGH ENOUGH FOR A DAILY SEVERE WEATHER THREAT AT WELL.
STRONG WINDS, HAIL, AND HEAVY RAINFALL LEADING TO FLASH FLOODING
WILL BE POSSIBLE EACH AFTERNOON/EVENING THIS WEEKEND. IT IS
IMPORTANT TO NOTE, THAT WITH THE RAIN CHANCES FRIDAY THROUGH
SUNDAY, NOT EVERY LOCATION IN OUR CWA WILL RECEIVE RAIN EACH DAY.
BUT, BY THE END OF THE WEEKEND MANY LOCATIONS WILL LIKELY SEE SOME
RAINFALL, WITH POTENTIAL FOR THAT RAIN TO BE HEAVY AT TIMES.
RAIN CHANCES WILL DECREASE FOR MONDAY AND TUESDAY (STILL A LOW
CHANCES, BUT NOT AS HIGH AS PREVIOUS DAYS) AS THE UPPER LEVEL HIGH
BUILDS TO OUR SOUTH AND THE FLOW ALOFT TURNS MORE ZONAL, CUTTING OFF
THE MONSOONAL MOISTURE. TEMPERATURES WILL WARM CLOSER TO NORMAL OR
SLIGHTLY ABOVE NORMAL DURING THIS TIME, WITH HIGHS AROUND 90
DEGREES IN THE URBAN CORRIDOR AND PLAINS BY TUESDAY. THERE'S QUITE
A BIT OF UNCERTAINTY BEYOND TUESDAY. SOME MODELS AND ENSEMBLE
MEMBERS BRING A WEAK FRONT AND A DECENT SHORTWAVE ON WEDNESDAY,
LOWERING TEMPERATURES AND BRINGING ADDITIONAL RAIN CHANCES TO THE
AREA. WHILE OTHER ENSEMBLE MEMBERS, HAVE A MUCH WEAKER SHORTWAVE
(IF ANYTHING AT ALL), CAUSING VERY LITTLE CHANGE IN TEMPERATURES
FOR WEDNESDAY.

A LOW STRATUS DECK IS CURRENTLY OVER KDEN AND KAPA. CEILINGS AT
KBJC WERE MVFR TO IFR OVERNIGHT, BUT HAVE SINCE LIFTED. CEILINGS
AT KDEN WILL SLOWLY LIFT OVER THE NEXT COUPLE OF HOURS, LIFTING
AND SCATTERING OUT BETWEEN 14Z AND 15Z. KAPA IS CURRENTLY
BOUNCING BETWEEN A SCT006 AND BKN006. IT WILL CONTINUE TO DO THIS
FOR THE NEXT HOUR OR TWO BEFORE THE CEILINGS START TO LIFT AND
CLEAR. WE'RE EXPECTING ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS
THIS AFTERNOON AND EVENING. THE MAIN WINDOW FOR THUNDERSTORM
ACTIVITY WILL BE BETWEEN 20Z AND 24Z, WITH THE POTENTIAL FOR SOME
LINGERING SHOWERS AND STORMS INTO THE LATE EVENING. WINDS TODAY
WILL BE VARIABLE IN WIND SPEED AND DIRECTION, AS OUTFLOWS FROM
NEARBY CONVECTION CAUSE RAPID WIND SHIFTS. AFTER THE STORMS MOVE
OUT OF THE AREA, WINDS WILL BE LIGHT AND VARIABLE OR LIGHT FROM
THE SOUTHWEST.
BOU WATCHES/WARNINGS/ADVISORIES
NONE.
