What forecasters said that day

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Albuquerque, NM wrote its last area forecast discussion before this flash flood warning went out at Jul 21, 2:24 PM MDT, 2 hours 17 minutes earlier.

Area forecast discussion, Jul 21, 2:24 PM MDT, 2 hours 17 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBUQUERQUE NM
224 PM MDT MON JUL 21 2008

.DISCUSSION...
BROAD AREA OF HIGH PRESSURE WILL REMAIN OVER THE SW U.S. THROUGH THE
FORECAST PERIOD. HIGH CENTERS WILL SHIFT FROM TIME TO TIME...MAKING
THE DIRECTION OF STORM MOVEMENT DIFFICULT FROM DAY TO DAY. THE HIGH
WILL LIKELY SHIFT TO THE N OF NM AS THE WEEK PROGRESSES...IN RESPONSE
TO THE REMNANTS OF DOLLY MOVING INTO TEXAS.

STORMS FIRING OVER A LARGER AREA TODAY COMPARED TO SUN...AS STORMS
HAVE FORMED OVER THE ERN HIGH PLAINS. STORM MOVEMENT IS THE EXACT
OPPOSITE OF YESTERDAY...MOVING TO THE S AND SE...SUGGESTING AN
UPPER HIGH CENTER IS BACK TO ERN AZ OR THE FOUR CORNERS AREA.

STORMS WILL CONTINUE INTO TONIGHT...FAVORING THE HIGH TERRAIN
THROUGH THE PM...THEN DROPPING INTO THE VALLEYS THIS EVE...AND
REMAINING OVER THE ERN HIGH PLAINS. LITTLE CHANGE IS EXPECTED
THROUGH THU. STORM MOVEMENT MAY BECOME MORE E TO W THOUGH AS THE
HIGH CENTERS SHIFT N. THEN WE WILL FOCUS ON WHAT HAPPENS TO DOLLY...
AS SHE IS FORECAST TO MAKE LANDFALL NEAR BROWNSVILLE WED. MOST MODELS
TAKE THE REMAINS W...WELL S OF IMPACTING NM. THE NAM AND DGEX THOUGH
BRING THE REMNANTS TOWARD SRN NM THU AND FRI...THEN WRAP THE MOISTURE
AROUND THE UPPER HIGH...CONTINUING TO IMPACT NM NEXT WEEKEND AND EVEN
EARLY NEXT WEEK. FOR NOW WILL KEEP MOSTLY ISOLATED POPS IN FOR THE
FRI THROUGH MON TIME PERIOD. CHJ

&&

.AVIATION...
THE MAIN FOCUS FOR LOCALIZED MVFR AND IFR CONDITIONS DUE TO
THUNDERSTORMS WILL BE FOUND ACROSS WESTERN AND CENTRAL AREAS OF THE
FORECAST AREA. THE MAIN PERIOD WILL BE NOW THROUGH 3Z. LOOK FOR A
LESSENING IN IFR AND MVFR COVERAGE LATE EVENING INTO THE MORNING
HOURS ON TUESDAY. GUSTY WINDS WILL ALSO BE ASSOCIATED WITH THE
THUNDERSTORMS. GENERALLY NO MORE THAN 33 KT BUT SOME GUSTS WILL BE
AS HIGH AS 40 KT.

NEXT AVIATION DISCUSSION SCHEDULED FOR 09Z.

&&

.FIRE WEATHER...
UPPER HIGH OVER SOME PORTION OF NM WILL KEEP MOISTURE TRAPPED
UNDERNEATH IT THROUGH WORK WEEK. THE MAIN FOCUS FOR WETTING SHOWERS
AND STORMS WILL BE FOUND ACROSS WESTERN AND CENTRAL AREAS...AT LEAST
THROUGH THE NEAR TERM. STORM MOVEMENT WILL BE SLOW THUS ALLOWING A
BETTER CHANCE OF WETTING RAIN. MINIMUM HUMIDITY IS EXPECTED TO BE
HIGHER THAN 20 PCT THROUGH THE WORK WEEK. GOOD TO EXCELLENT OVERNIGHT
RECOVERIES AS WELL. ONE WILDCARD LATER IN THE WEEK OR OVER THE
WEEKEND WILL BE TROPICAL STORM DOLLY. DOLLY IS EXPECTED TO BECOME A
HURRICANE OVER THE GULF OF MEXICO. VARIOUS MODELS GIVE VARIOUS TRACKS
SO THERE IS UNCERTAINTY AS TO WHERE THIS STORM AND ITS MOISTURE/DRY
SLOT WILL END UP.
