$$What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Pueblo, CO wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 18, 2:52 PM MDT, 2 hours 3 minutes earlier.
Area forecast discussion, Jul 18, 2:52 PM MDT, 2 hours 3 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 252 PM MDT FRI JUL 18 2008 .SHORT TERM... (TONIGHT AND SATURDAY) FORECAST CHALLENGE IS AGAIN THUNDERSTORM COVERAGE CURRENTLY TWO UPPER FEATURES WORKING ON FORECAST AREA PRODUCING ISOLATED TO SCATTERED THUNDERSTORMS. FIRST FEATURE IS A PLUME OF MOISTURE THAT EXTENDS INTO SOUTHERN COLORADO FROM NORTHER NEW MEXICO AND ARIZONA. THUNDERSTORMS DEVELOPING MAINLY OVER SOUTHERN SANGRE DE CRISTO MOUNTAINS AND PIKES PEAK/PALMER DIVIDE. SECOND FEATURE IS A SHORT WAVE WORKING INTO WESTERN COLORADO PRODUCING THUNDERSTORMS ALONG CONTINENTAL DIVIDE. SURFACE DEW POINTS REMAIN IN THE 50S OVER THE PLAINS WITH 40S TO THE WEST. PLENTY TO WORK WITH IF WE CAN GET THE UPPER SUPPORT. TONIGHT...LOOKS LIKE SOUTHWEST PLUME WILL VEER EAST AND AFFECT MOSTLY SOUTHERN AREAS WHILE WESTERN SHORT WAVE IMPACT CENTRAL MOUNTAINS AND NORTH. RAISED POPS EARLIER TODAY TO SUGGEST BETTER COVERAGE GIVEN THE TWO FEATURES. HELD THOSE POPS UP THROUGH THE EVENING THEN TAPERED THEM OFF AFTER 03Z. KEPT LOW POPS ALONG SOUTHERN TIER OVERNIGHT. SATURDAY...WEDGE OF DRIER AIR MOVES INTO THE REGION AS UPPER HIGH REBUILD OVER US. STAYED WITH CURRENT FORECAST POPS/TEMPS THAT REFLECT VERY WARM TEMPS AND DRY CONDITIONS EXCEPT FOR LOW POPS SOUTHWEST MOUNTAINS. .LONG TERM... (SUNDAY THROUGH FRIDAY) ...HOT AND MOSTLY DRY WEATHER SOUTHEAST CO SUN-MON... ...A MORE ACTIVE THUNDERSTORM PATTERN STILL POSSIBLE TUE-FRI... SUNDAY AND MONDAY...MODELS CONTINUE TO SUPPORT THE 500MB HIGH PRESSURE SYSTEM TO BE CENTERED OVER EAST CENTRAL-NORTHEAST CO SUNDAY AND POSSIBLY INTO MONDAY. THE DEEPER RIDGE OF MOISTURE WILL SETTLE FURTHER WEST FROM AZ TO THE GREAT BASIN INTO WESTERN CO EACH DAY. IT IS POSSIBLE THIS MOISTURE RIDGE MAY SHIFT A LITTLE FURTHER EAST ON MONDAY. THE COMBINATION OF DAYTIME HEATING...WEAK UPPER LEVEL DISTURBANCES...AND THE MOISTURE RIDGE WILL SUPPORT THUNDERSTORM DEVELOP...PRIMARILY ALONG THE CONTINENTAL DIVIDE AND WESTWARD. THE THUNDERSTORM STEERING CURRENTS WILL BE WESTERLY(FROM THE EAST TO THE WEST) ACROSS MUCH OF SOUTHERN CO. SURFACE BASED THUNDERSTORM DEVELOPMENT ACROSS SOUTHEAST CO PLAINS SHOULD BE AT A MINIMUM OR NIL GIVEN THE RELATIVELY STRONG CAPPING INVERSION ALOFT SUPPRESSING ANY SURFACE BASED THUNDERSTORM INITIATION. ANY THUNDERSTORMS THAT DEVELOP OVER THE SOUTHEAST CO MOUNTAINS WILL MOVE WESTWARD AND NOT TYPICALLY INTO THE I-25 CORRIDOR...SO THE THREAT FOR PRECIPITATION WILL BE VERY LOW OR NIL ACROSS THE I-25 CORRIDOR SUNDAY AND MONDAY AFTERNOON/EVENING. THE MAIN THUNDERSTORM THREAT ACROSS THE CONTINENTAL DIVIDE...ESPECIALLY THE SOUTHWEST MOUNTAINS...WILL BE LOCALLY MODERATE TO HEAVY RAIN GIVEN 700-500MB SPECIFIC HUMIDITY VALUES OF 6-7.5 G/KG...FREEZING LEVEL 14K-17K FT MSL... AND STEERING CURRENTS OF 10KTS OR LESS. HOT SURFACE TEMPERATURES WILL CONTINUE WITHIN THE HIGH PRESSURE SYSTEM ALOFT GIVEN 700MB TEMPERATURES OF +18C TO +21C GENERALLY ALONG THE I-25 CORRIDOR AND MOUNTAINS/HIGH VALLEYS. HIGH TEMPERATURES AROUND 100F WILL STILL BE LIKELY FROM PUEBLO TO LA JUNTA SUNDAY AND MONDAY AFTERNOON. TUESDAY THROUGH FRIDAY...VERY CHALLENGING FORECAST AND IT DEPENDS ON ACTUALLY WHERE THE MIDDLE TO UPPER LEVEL HIGH PRESSURE RESIDES. THE DGEX AND ECMWF CONTINUE TO PROJECT THE UPPER HIGH TO SHIFT A LITTLE FURTHER EAST OF THE ROCKIES AND WOULD SUPPORT...ALBEIT WEAK... RELATIVELY DEEP SOUTH-SOUTHWESTERLY FLOW ACROSS THE DESERT SOUTHWEST INTO THE GREAT BASIN AND CENTRAL ROCKIES. THE DEGREE OF MONSOONAL MOISTURE THAT MIGRATES INTO THE CENTRAL ROCKIES IS STILL THE WILDCARD FOR TUESDAY THROUGH THURSDAY. THE DGEX WANTS TO SHIFT THE 700-500MB MOISTURE LAYER OF SPECIFIC HUMIDITIES OF 5-7 G/KG INTO MUCH OF CO TUESDAY THROUGH THURSDAY. IF THIS OCCURS... THEN A LITTLE HIGHER GRADE MOISTURE WILL BE ACROSS CO WITH THE POTENTIAL FOR MODERATE TO HEAVY RAINFALL IN A SHORT PERIOD OF TIME GIVEN THE AMPLE MOISTURE...FREEZING LEVEL 16K-17K FT MSL...AND STEERING CURRENTS 5KTS OR LESS...ESPECIALLY OVER THE MOUNTAINS/HIGH VALLEYS AND I-25 CORRIDOR. BY FRIDAY...THERE IS THE POTENTIAL FOR THE UPPER LEVEL HIGH TO RECENTER ITSELF OVER CO. ON THE OTHER HAND... THE GFS ENSEMBLE DATA SUGGESTS THE UPPER HIGH COULD REMAIN DIRECTLY OVER CO THROUGH THE PERIOD. IF THIS OCCURS...THEN THE HIGH QUALITY MOISTURE WILL REMAIN TO OUR SOUTH AND WEST OF CO. WITHIN THE HIGH PRESSURE CENTER...MOISTURE SHOULD JUST RECYCLE ITSELF FROM DIURNAL ISOLATED-SCATTERED THUNDERSTORMS. TEMPERATURES SHOULD BE AROUND OR SLIGHTLY ABOVE SEASONAL NORMS THROUGH THE PERIOD. METZE && .AVIATION... SCATTERED MOUNTAIN THUNDERSTORMS UNTIL 03Z. ISOLATED OVER THE PLAINS. POSSIBLE MVFR CIGS OVER EASTERN PLAINS AFTER 09Z OTHERWISE VFR. && .PUB WATCHES/WARNINGS/ADVISORIES... NONE. && 21/17
