Areal Flood Warning 2, NWS Goodland, KS

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
515 AM MDT TUE JUN 24 2014

.SHORT TERM...(TODAY THROUGH THURSDAY NIGHT)
ISSUED AT 335 AM MDT TUE JUN 24 2014

AS OF 4 AM CDT...3 AM MDT...SKIES ACROSS THE TRI-STATE AREA WERE
OVERCAST. TEMPERATURES RANGED FROM THE MID 50S OVER EAST COLORADO TO
THE UPPER 60S ACROSS NORTON...GRAHAM AND GOVE COUNTIES IN NORTHWEST
KANSAS. WINDS WERE LIGHT AND VARIABLE ACROSS THE REGION WITH SEVERAL
CONVECTIVE OUTFLOWS MOVING THROUGH. SHOWERS AND THUNDERSTORMS WERE
MOVING ACROSS LOCATIONS ALONG AND JUST NORTH OF INTERSTATE 70. SOME
STORMS HAVE PRODUCED HEAVY RAINFALL...ESPECIALLY OVER NORTHEAST
COLORADO. FLASH FLOOD WARNINGS CONTINUE OVER NORTHEAST COLORADO AND
EXTREME NORTHWEST KANSAS AS HEAVY RUNOFF POSES A THREAT OF RAPID
RISES ON THE SOUTH FORK OF THE REPUBLICAN RIVER.

FIRST OF ALL...APOLOGIZE FOR THE BREVITY AND LATENESS OF THIS
FORECAST DISCUSSION. THIS IS DUE TO ONGOING CONVECTION AND FLOODING
CONCERNS.

MAIN CONCERNS FOR THE NEXT THREE DAYS ARE CHANCES OF STRONG TO
SEVERE THUNDERSTORMS AND THREAT OF ADDITIONAL HEAVY RAINFALL.

FOR TODAY...THERE IS A LARGE AMOUNT OF UNCERTAINTY IN THE EXPECTED
WEATHER FOR TODAY. SHOWERS AND THUNDERSTORMS SHOULD CONTINUE INTO
THE MORNING HOURS FOR LOCATIONS ALONG AND NORTH OF INTERSTATE 70.
DUE TO THIS ACTIVITY...AFTERNOON CONVECTION MAY BE LIMITED FOR THESE
LOCATIONS DUE TO A STABILIZED...WORKED OVER ENVIRONMENT IN PLACE. IN
ADDITION...COOLER TEMPERATURES DUE TO LINGERING CLOUD COVER ARE
EXPECTED WHICH WILL ALSO HELP LOWER INSTABILITY. LATER THIS
AFTERNOON...ANOTHER SHORTWAVE TROUGH...CURRENTLY LOCATED OVER
CENTRAL UTAH...WILL PASS THROUGH. THIS SHORTWAVE WILL LEAD TO NEW
CONVECTIVE DEVELOPMENT ACROSS EAST COLORADO. THE THREAT OF SEVERE
WEATHER TODAY SHOULD BE CONFINED TO LOCATIONS THAT EXPERIENCE
SUFFICIENT AIRMASS RECOVERY. FOR OUR AREA...THIS INCLUDES THE EAST
COLORADO COUNTIES AND NORTHWEST KANSAS COUNTIES SOUTH OF INTERSTATE
70 AND WEST OF HIGHWAY 83. LARGE HAIL...DAMAGING WINDS AND HEAVY
RAINFALL ARE THE MAIN THREATS. STORMS SHOULD BE ISOLATED TO
SCATTERED INITIALLY BEFORE CONGEALING INTO AN MCS LATER IN THE
EVENING AND MOVING ACROSS WEST CENTRAL KANSAS.

FOR TOMORROW...A POTENTIALLY MORE ACTIVE DAY WITH REGARDS TO SEVERE
WEATHER IS EXPECTED. THERE REMAINS SOME UNCERTAINTY WITH SEVERE
CHANCES WEDNESDAY DUE TO POTENTIAL AIRMASS STABILIZATION FROM STORMS
TODAY. HOWEVER...HIGHER INSTABILITY...WARMER TEMPERATURES AND 0-6 KM
BULK SHEAR OF 40 KTS SHOULD PROVIDE A SUFFICIENT ENVIRONMENT FOR
STRONG TO SEVERE THUNDERSTORMS...INCLUDING THE CHANCE OF A FEW
SUPERCELLS. ONCE AGAIN...THE MAIN THREATS SHOULD BE LARGE
HAIL...DAMAGING WINDS AND HEAVY RAINS. STORMS SHOULD DEVELOP OVER
EAST COLORADO AND SPREAD EAST ACROSS THE REGION DURING THE EVENING.

LESS ACTIVITY IS ANTICIPATED ON THURSDAY. MODELS ARE INDICATING A
SOMEWHAT CAPPED ATMOSPHERE WITH SOME SUBSIDENCE ALOFT AHEAD OF THE
NEXT SHORTWAVE ANTICIPATED FOR FRIDAY. HOWEVER...A FEW STRONG TO
SEVERE THUNDERSTORMS ARE POSSIBLE.

.LONG TERM...(FRIDAY THROUGH MONDAY)
ISSUED AT 232 AM MDT TUE JUN 24 2014

LARGE SCALE PATTERN SHOWS THE UPPER RIDGE OVER THE PLAINS BEGINNING
TO MOVE EAST AND AN UPPER TROUGH OVER THE PACIFIC NORTHWEST MOVING
INTO THE NORTHERN AND CENTRAL PLAINS ON FRIDAY. WHILE MODELS ARE IN
FAIRLY GOOD AGREEMENT...MODELS HAVE NOT BEEN CONSISTENT FROM RUN TO
RUN. NOT EXACTLY SURE AT THIS POINT HOW THIS UPPER TROUGH WILL
AFFECT THE CWA OVER THE WEEKEND SINCE MODELS HAVE BEEN GOING BACK
AND FORTH WITH THE SOUTHERN EXTENT OF THE TROUGH. THE UPPER TROUGH
WILL CONTINUE TO MOVE EAST THROUGH SUNDAY WITH AN UPPER LEVEL HIGH
SETTING UP OVER THE SOUTHWESTERN UNITED STATES AND THE SOUTH CENTRAL
PLAINS. THE ALLBLEND STILL HAS PRECIPITATION CHANCES THROUGH MOST OF
THE WEEKEND FROM NUMEROUS DISTURBANCES MOVING THROUGH THE FLOW ALOFT
...WITH A BREAK ON SUNDAY AND MONDAY.  THIS SEEMED REASONABLE TO
ACCEPT ONCE AGAIN DUE TO CONSISTENCY IN MODEL RUNS.

A SURFACE LOW WILL SET UP OVER THE CWA THROUGH THE EXTENDED...WITH A
TROUGH AXIS AND QUASI STATIONARY FRONT LINGERING OVER THE CWA FOR
MOST OF THE EXTENDED WITH A COLD FRONT MOVING THROUGH ON SATURDAY. THE GFS
HAS GOOD INSTABILITY AND GOOD LOW LEVEL MOISTURE AHEAD OF THE
SURFACE BOUNDARIES WITH GREAT SHEAR BEHIND THE SURFACE BOUNDARIES.
THEREFORE...THE POTENTIAL IS THERE FOR THUNDERSTORMS THAT DEVELOP TO
BECOME STRONG TO SEVERE. HOWEVER...GIVEN THE CONFIDENCE IN THIS
FORECAST...NOT SURE HOW THOSE FRONTS WILL SET UP AT THIS TIME AND
WANTED TO HOLD OFF ON SEVERE WORDING FOR NOW. THE ALLBLEND DID NOT
HAVE POPS IN FOR SUNDAY AND MONDAY...BUT THIS FAR OUT IT IS LIKELY
TO CHANGE GIVEN THE WESTERLY FLOW ALOFT AND WEAK WAVES MOVING
THROUGH THE HIGH PLAINS.

TEMPERATURES IN THE EXTENDED WILL BE WARM...WITH HIGHS IN THE LOW TO
MID 90S WITH THE EXCEPTION OF SATURDAY BEHIND THE COLD FRONT AS
HIGHS OVER THE NORTHWEST HALF OF THE CWA REACH THE MID 80S. LOW
TEMPERATURES WILL BE IN THE UPPER 50S WEST TO UPPER 60S/LOW 70S EAST.

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z WEDNESDAY MORNING)
ISSUED AT 515 AM MDT TUE JUN 24 2014

ACTIVE WEATHER PATTERN CONTINUES FOR AT LEAST THE NEXT 24 HOURS.
CONFIDENCE IS RELATIVELY LOW DUE TO UNCERTAINTY IN ATMOSPHERIC
STABILITY/INSTABILITY THIS AFTERNOON. CONVECTION TONIGHT SHOULD
HAVE STABILIZED THE ATMOSPHERE FOR TODAY...ESPECIALLY AT KMCK.
THEREFORE...REMOVED MENTION OF VCSH/VCTS FOR KMCK. AT KGLD...
BETTER AIRMASS RECOVER IS ANTICIPATED TO THE WEST. STORMS WILL
DEVELOP OVER EAST COLORADO AND MOVE EAST. PLACED VCTS AT KGLD
AFTER 23Z. A FEW MODELS ARE SHOWING A DECENT SIGNAL FOR
STRATUS/FOG AT BOTH SITES TOMORROW MORNING. MENTIONED A SCT010
GROUP TO HIGHLIGHT THIS BUT DIDNT WANT TO GET TOO SPECIFIC WITH
THIS THREAT AS CONVECTIVE CIRRUS...SIMILAR TO WHAT IS OVER TAF
SITES NOW...WOULD LIMIT BOUNDARY LAYER COOLING AND THUS
FOG/STRATUS DEVELOPMENT.

.GLD WATCHES/WARNINGS/ADVISORIES...

NE...NONE.
