AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GOODLAND KS 658 PM MDT FRI JUL 11 2014 .UPDATE... ISSUED AT 648 PM MDT FRI JUL 11 2014 UPDATED EVENING FORECAST TO REFLECT RADAR TRENDS AND LATEST MODEL DATA. AREA OF STORMS CONTINUES TO SLOWLY MOVE EAST-NORTHEAST TOWARD EAST CENTRAL COLORADO WHILE STORMS ALSO FIRE ALONG FRONTAL BOUNDARY/NOSE OF LOW LEVEL JET OVER THE WESTERN 1/3 OF THE AREA. LARGER AREA OF STORMS OVER NORTHEAST COLORADO APPEARS TO BE SURFACE BASED AS WELL AS THE STORMS ALONG THE FRONTAL BOUNDARY. HOWEVER OVER THE NEXT HOUR STORMS SHOULD BECOME MORE ELEVATED. RUC ANALYSIS PLACES 1500-2500J/KG OF ELEVATED CAPE BY LIFTING PARCEL FROM 800MB OVER THE NORTHERN HALF OF YUMA COUNTY...WITH LESS THAN 30 J/KG OF CINH. BEST INSTABILITY WILL BE DURING THE NEXT COUPLE OF HOURS THEN TAPER OFF AS ENVIRONMENT STABILIZES AND MORE UNSTABLE AIR MOVES NORTH OF THE AREA. KEPT LINGERING PRECIP. CHANCES INTO THE OVERNIGHT HOURS DUE TO NOSE OF LOW LEVEL JET REMAINING OVER THE FAR WESTERN PART OF THE AREA WITH ELEVATED CAPE FROM 700MB AROUND 800-900J/KG WITH CINH UNDER 40 J/KG. ANY ELEVATED CONVECTION SHOULD END BEFORE SUNRISE DUE TO THE NOSE OF THE LOW LEVEL JET MOVING FURTHER SOUTH AWAY FROM THE ELEVATED INSTABILITY. && .SHORT TERM...(THIS EVENING THROUGH SATURDAY) ISSUED AT 141 PM MDT FRI JUL 11 2014 TONIGHT... HOT CONDITIONS ACROSS THE CWA THIS AFTERNOON WITH TEMPERATURES RANGING IN THE MID TO UPPER 90S...WITH ONLY SCATTERED MID/HIGH CLOUDS AROUND THE AREA. WARMTH TO CONTINUE INTO THE OVERNIGHT HOURS WITH SOME INCREASING CLOUDS AS CONVECTIVE ACTIVITY SLOWLY SHIFTS EASTWARD FROM THE ROCKIES ALONG FRONTAL BOUNDARY. MAIN AFFECTED AREAS WILL BE OVER WESTERN ZONES BASED ON TRACK OF EXPECTED STORMS...AS LOW PRESSURE SITTING ALONG THE BOUNDARY WILL LIFT NE THROUGH THE OVERNIGHT. HIGHEST POP CHANCES WILL BE WEST...TAPERING TO NOTHING OVER CENTRAL AND EASTERN ZONES. IF ANY STORMS DO DEVELOP...LOCALIZED DOWNPOURS COULD ENSUE WITH PW/S OVER AN INCH. BEST MODEL INSTABILITY FROM LAPS CAPE/LI STILL FAVOR WESTERN ZONES OVERNIGHT. LOOKING FOR OVERNIGHT LOWS TO RANGE IN THE 60S...AND WINDS 15-25 MPH W/ LOCALIZED GUSTS NEAR 30 MPH SHIFTING FROM WEST TO EAST OVERNIGHT. SATURDAY... REMNANTS OF FRONT GOING INTO SATURDAY WILL REMAIN ALONG OR JUST NORTH OF NORTHERN BORDER ZONES...WITH LIGHT RW/-TRW POSSIBLE. MODELS CONTINUE TO SHOW COLD FRONT TO THEN SINK SE SLOWLY ACROSS THE CWA THROUGH THE DAY SATURDAY. BEST DYNAMICS SUPPORT MORE AREAL COVERAGE OF PRECIPITATION AFTER 18Z TOWARDS 00Z SUNDAY. DAYTIME HEATING IN CENTRAL AND SOUTHERN ZONES WILL AID IN FURTHER DESTABILIZING AIR MASS BEFORE FRONT TRAVERSES AREA...ALLOWING FOR INCREASED POP COVERAGE. STAYING CLOSE TO MODEL GUIDANCE FOR HIGHS WHICH WILL RANGE IN MID 80S TO LOWER 90S WITH HIGHEST TEMPERATURES SOUTH DUE TO LACK OF FRONTAL CLOUD COVER. .LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY) ISSUED AT 240 PM MDT FRI JUL 11 2014 A DEEP UPPER LOW NEAR HUDSON BAY AT BEGINNING OF PERIOD WILL ROTATE SOUTH INTO MINNESOTA BY MONDAY MORNING AND THEN SWING EAST THROUGH THE EASTERN GREAT LAKES BY LATE TUESDAY. THIS WILL BRING A SIGNIFICANT CHANGE TO THE PATTERN WITH MUCH COOLER AIR SETTLING INTO THE CENTRAL PLAINS STARTING LATE MONDAY. AT THE SURFACE...A COLD FRONT WHICH SETTLED SLOWLY SOUTH ON SATURDAY WILL CONTINUE DROPPING DOWN INTO OKLAHOMA BY SUNDAY MORNING. AS THE UPPER PATTERN AMPLIFIES MONDAY...A STRONGER REINFORCING SHOT OF CANADIAN AIR WILL ARRIVE MONDAY AFTERNOON AND DOMINATE THROUGH MID WEEK. HIGH TEMPERATURES WILL REMAIN IN THE 80S SUN-MON BUT WILL ONLY REACH THE MIDDLE 70S TUE-WED WHICH IS AROUND 15-20 DEGREES BELOW NORMAL. A SLOW WARMUP WILL OCCUR AT THE END OF THE WEEK. THE FIRST CHANCE FOR PRECIPITATION IN THE EXTENDED PERIOD WILL BE SATURDAY NIGHT BEHIND THE WEAK COLD FRONT MOVING SOUTH AS A SHORT WAVE TROUGH IN MID LEVELS DROPS SOUTHEAST. NOT EXPECTING ANY HEAVY AMOUNTS THOUGH. AFTER THAT...THE NEXT FEATURE TO INCREASE PRECIP POTENTIAL WILL BE A JET STREAK WHICH WILL SLIDE SOUTHEAST FROM WYOMING SUNDAY NIGHT. THIS WILL GENERATE SCATTERED SHOWERS/TSTORMS FROM NORTHEAST COLORADO INTO NORTHWEST KANSAS PRODUCING LIGHT RAINFALL AMOUNTS. FINALLY...THE MAIN COLD FRONT WILL ARRIVE MONDAY AFTERNOON PRODUCING THUNDERSTORMS...MAINLY IN THE AFTERNOON- EVENING AND MAINLY SOUTH OF INTERSTATE 70 IF CURRENT TIMING UNFOLDS AS PLANNED. BOTH THE ECMWF AND GFS INDICATE PRECIPITATION CHANCES CONTINUING THROUGH MID WEEK...MAINLY IN THE WEST HALF OF THE CWA...AS A COUPLE MID LEVEL TROUGHS MOVE OVER THE AREA. THE BEST MOISTURE AND INSTABILITY WILL BE WELL TO THE SOUTH DURING THIS PERIOD HOWEVER...SO PRECIP AMOUNTS WILL BE ON THE LIGHTER SIDE. && .AVIATION...(FOR THE 00Z TAFS THROUGH 00Z SATURDAY EVENING) ISSUED AT 549 PM MDT FRI JUL 11 2014 VFR CONDITIONS FORECAST FOR THE 0Z TAFS. BREEZY TO GUSTY WINDS WILL GRADUALLY DIMINISH THIS EVENING. SOMEWHAT UNCERTAIN AS TO WHEN THAT WILL BEFORE KMCK SINCE GUIDANCE ALL SUGGEST WINDS SHOULD BE FROM THE SOUTHEAST AND NOT THE SOUTH AS THEY CURRENTLY ARE. BEST GUESS IS WHEN WINDS DECLINE THIS EVENING THEY SHOULD BE MORE FROM THE SOUTHEAST BY THAT TIME. ONE OF THE NEAR TERM MODELS WAS INDICATING IFR CEILINGS OVERNIGHT FOR BOTH SITES. WILL WAIT TO SEE WHAT THE LATEST RUN OF THE MODELS SAY FOR THE NEXT SET OF TAFS BEFORE COMMITTING. STORMS SHOULD REMAIN NORTH OF THE TAF SITES TO NOT NEED A MENTION IN THE TAFS. KMCK WILL BE THE ONLY ONE WHICH STORMS MAY MOVE CLOSE TO...BUT THE EAST-NORTHEAST STORM MOVEMENT SHOULD KEEP THEM AWAY FROM THE SITE. OTHERWISE SCATTERED STORMS ARE EXPECTED SATURDAY AFTERNOON AS AN UPPER LEVEL SHORT WAVE TROUGH MOVES THROUGH. CURRENTLY DO NOT HAVE ENOUGH CONFIDENCE THEY WILL BE CLOSE ENOUGH TO TAF SITES TO INCLUDE A MENTION IN THEM. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE.

HUSTEDThe radar
The Goodland radar (KGLD), 91 km away, was scanning. The volume nearest the first event began at 02:18 UTC.
Event by event
1 hail, 1 flash flood, 1 flood. Local standard time, as filed.
Flash Flood, Kit Carson
- When
- July 11, 7:30 PM MST to 10:30 PM MST
- Where
- Kit Carson County, 13.47 mi N of Seibert to 13.08 mi N of Seibert
- Cause
- Heavy Rain
- Reported by
- CoCoRaHS
- Coordinates
- 39.492, -102.836
Extreme rainfall rates of 2.5 inches per hour resulted in flash flooding where Hell Creek crosses Road 17 near Road JJ. This location is about 13 miles north of Seibert. Several feet of water was noted over Road 17.
Flood, Kit Carson
- When
- July 11, 10:30 PM MST to July 12, 2:30 AM MST
- Where
- Kit Carson County, 13.47 mi N of Seibert to 13.08 mi N of Seibert
- Cause
- Heavy Rain
- Reported by
- CoCoRaHS
- Coordinates
- 39.492, -102.836
Earlier flash flooding at this location took several more hours for water to recede. The following day the road was no longer covered with water but was still impassible due to muddy conditions.
What these are
- Hail
- Hail three-quarters of an inch or larger, or smaller hail that caused damage, filed with the largest stone measured.
- Flash Flood
- Flooding that begins within six hours of the rain that causes it, or of a dam or levee failure or ice jam release, often with deadly speed.
- Flood
- Flooding that develops more slowly than a flash flood: rivers leaving their banks, or water standing over land for an extended time.
After NWS Directive 10-1605, the rules offices file Storm Data by.
