AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
941 AM MDT THU SEP 12 2013

.UPDATE...MAJOR FLOODING/FLASH FLOODING EVENT UNDERWAY AT THIS
TIME WITH BIBLICAL RAINFALL AMOUNTS REPORTED IN MANY AREAS IN/NEAR
THE FOOTHILLS. PRECIPITABLE WATER VALUES IN EXCESS OF AN INCH AND
A QUARTER ON GPS SENSORS CERTAINLY SUPPORT LOTS MORE RAIN TODAY
AND TONIGHT.  13Z HRRR RUN HAS ANOTHER 1-3 INCHES OF RAIN
PREDICTED IN THE FOOTHILLS THROUGH 04Z SO THINGS ARE NOT LOOKING
GOOD. WILL EXTEND THE AREA OF THE FLASH FLOOD WATCH TO INCLUDE
ZONE 43 AND ALSO EXTEND IT IN TIME THROUGH 12Z TOMORROW MORNING.

&&

.AVIATION...UPSLOPE CONDITIONS WILL PERSIST THROUGH TODAY WITH LOTS
OF LOW CLOUDINESS AND SHOWER ACTIVITY EXPECTED.

&&

.HYDROLOGY...FLOODING ONGOING IN LOTS OF SPOTS INCLUDING THE
FOOTHILLS BURN AREAS. A DIRE SITUATION WHICH WILL NOT IMPROVE
DURING THE NEXT 24 HOURS.

&&

.PREV DISCUSSION... /ISSUED 446 AM MDT THU SEP 12 2013/

SHORT TERM...LITTLE CHANGE IN THE OVERALL PATTERN DURING THE
NEXT 24 HOURS. UPPER LEVEL LOW CENTERED OVER THE SOUTHERN GREAT
BASIN WILL SLOWLY SHIFT NORTHWARD TOWARDS SOUTHEAST IDAHO NEXT 24
HOURS. A VERY MOIST SOUTH-SOUTHWEST FLOW ALOFT...AND A VERY MOIST
SOUTHEASTERLY LOW-LEVEL FLOW WILL PROBABLY SET THE STAGE FOR
ANOTHER ROUND OF MODERATE TO HEAVY WARM PROCESS RAINFALL OVER AND
ALONG THE COLORADO FRONT RANGE THIS AFTERNOON AND EVENING.
VERY HEAVY RAINFALL OVER THE PAST 12 HOURS...SATURATED SOILS AND
THE MODERATE TO HEAVY RAINFALL EXPECTED AGAIN THIS AFTERNOON AND
EVENING NECESSITATE ISSUANCING A FLASH FLOOD WATCH FOR THE FRONT
RANGE FOOTHILL ZONES 35/36 AND I-25 URBAN CORRIDOR ZONES
38..39..40 AND 41. WATCH WILL RUN FROM 18Z/TODAY TO 06Z/TONIGHT.
MODERATE TO HEAVY RAINFALL STILL OCCURRING OVER AND NEAR THE
FOOTHILLS AT THIS HOUR. COULD SEE SIMILAR RAINFALL RATES FOR THE
NEXT FEW HOURS BEFORE LETTING UP AROUND MID-MORNING. AREAS OF
DENSE FOG ON THE PLAINS MAY BE AN ISSUE AROUND SUNRISE. RAINFALL
AMOUNTS TODAY NOT EXPECTED TO BE AS GREAT AS THOSE OBSERVED DURING
THE PAST 18 HOURS...BUT IT WOULDN/T TAKE MUCH TO CAUSE FLOODING
AGAIN. RAINFALL EXPECTED TO BECOME HEAVIER AND MORE WIDESPREAD
LATER THIS AFTERNOON AND EVENING IN ADVANCE OF A WEAK SHORT WAVE
TROUGH LIFTING NORTHWARD ACROSS THE REGION OVERNIGHT. SHOULD SEE
LITTLE IF ANY SUNSHINE EAST OF THE MTNS TODAY.
CONSEQUENTLY...LITTLE WARMING TODAY. WHEREAS AREAS ON THE WEST
SLOPE COULD SEE A BIT MORE SUNSHINE WITH LOW-LEVEL EASTERLY/
DOWNSLOPE FLOW. HOWEVER WITH ALL THE MOIST AIR AROUND...SUNSHINE
WILL HAVE LITTLE PROBLEM GENERATING T-STORMS THIS AFTERNOON.

LONG TERM...ON FRIDAY...AIRMASS NOT QUITE AS MOIST WITH THE
UPPER LOW TRACKING NORTHEAST TOWARDS WYOMING. THIS CAUSES THE
FLOW ALOFT TO BECOME MORE SOUTHWESTERLY. THIS RESULTS IN MODEST
DRYING AT MID-LEVELS...ESPLY WEST OF THE FRONT RANGE. CONSEQUENTLY
RAIN CHANCES SLIGHTLY LOWER...PARTICULARLY IN THE HIGH COUNTRY
WEST OF THE CONTINENTAL DIVIDE. MORE SUNSHINE IN THESE AREAS WILL
WARM TEMPERATURES A FEW DEGS C. EAST OF THE MTNS LITTLE WARMING
ANTICIPATED.

ON SATURDAY...DRYING PROGRESSES AS THE UPPER LOW OPENS UP INTO AN
OPEN TROUGH. TROUGH SWINGS ACROSS WYOMING AND MONTANA CAUSING WINDS
ALOFT TO GO MORE WESTERLY. THIS WILL HELP DRY AIR THE PLAINS AIRMASS
AND LOWER THE CHANCE OF SHOWERS/T-STORMS EAST OF THE MTNS.
TEMPERATURES ALSO RETURN TO NEAR AVERAGE FOR THE DATE.

SATURDAY NIGHT AND SUNDAY...AS THE UPPER TROUGH PASSES TO OUR
NORTH...A COLD FRONT DROPS SOUTH OUT OF WYOMING AND INTO NORTHEAST
COLORADO TOWARDS MORNING. POST FRONTAL UPSLOPE FLOW COMBINED WITH A
FAIR AMOUNT OF MOISTURE AROUND EXPECTED TO GENERATE SCATTERED
SHOWERS/ISOLATED T-STORMS ACROSS THE FORECAST AREA...POSSIBLY MORE
SO UP ALONG THE FRONT RANGE AND OVER THE PALMER DIVIDE DURING THE
AFTERNOON. HEAVY RAINFALL AND THEREFORE THE FLOOD RISK APPEARS LOW
WITH THESE STORMS. SUNDAY TEMPERATURES COOL 3-4C EAST OF THE
MTNS...BUT LITTLE CHANGED WEST OF MTNS.

MONDAY THROUGH WEDNESDAY...EXPECT DRIER AND WARMER CONDITIONS
AREAWIDE WITH ZONAL FLOW.

AVIATION...LOW CEILINGS AND AREAS OF FOG PRODUCING INSTRUMENT
FLIGHT RULES AT DENVER AREA AIRPORTS NEXT 12-24 HOURS. LOWEST CIGS
AND VSBYS EXPECTED ALONG THE FOOTHILLS AT BJC AND APA. EAST-
SOUTHEAST WINDS OF 6-14KTS EXPECTED TODAY. TONIGHT WINDS
GRADUALLY SHIFT TO A NORTH-NORTHWEST DIRECTION AFTER 06Z TONIGHT.

HYDROLOGY...FLASH FLOOD WATCH FROM NOON TODAY TO MIDNIGHT TONIGHT
FOR THE FRONT RANGE FOOTHILL ZONES 35 AND 36...AND THE ADJACENT
I-25 URBAN CORRIDOR ZONES 38...39...40 AND 41. PERIODS OF HEAVY
RAIN IN THESE AREAS COUPLED WITH SATURATED SOILS COULD RESULT IN
ADDITIONAL FLASH FLOODING LATER TODAY. MODERATE TO HEAVY RAINFALL
STILL OCCURRING AT THIS HOUR ALONG THE NORTHERN FRONT RANGE COULD
PROMPT ADDITIONAL FLOOD/FLASH FLOOD WARNINGS DURING THE NEXT 3-5
HOURS.
