AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS

.DISCUSSION...
COMPLEX WEATHER SCENARIO TODAY WITH POSSIBLE SEVERE WEATHER TAKING
SHAPE. 12Z ANALYSIS INDICATES A S/WV TROF NEAR NRN MT WITH ITS SFC
REFLECTION OVR THE DAKOTAS. A FRONTAL BOUNDARY LIES FROM THE DAKOTAS
TO THE NE PANHANDLE THEN WESTWARD ACROSS NRN UT AND CO. CONVECTION
STILL ONGOING IN NORTH CENTRAL KS...TRIGGERED BY AN OUTFLOW BOUNDARY
IN ERN KS. SEVERE ACTIVITY HAS ALREADY BROKEN OUT IN NORTH CENTRAL
NE AS EVIDENT FROM LATEST RADAR IMAGERY. EXPECT MORE STORMS TO
INITIATE IN THE SAME RGN AND MOVE TO THE SOUTHEAST. ALTHOUGH SPEED
SHEAR IS NOT TOO IMPRESSIVE...SOUTHEASTERLY LLVL FLOW WITH NORTHWEST
FLOW ALOFT CAN HELP MAKE UP FOR THE LACK OF SPEED SHEAR. ALL IN ALL
THINGS ARE SHAPING UP TO BE A BUSY NIGHT PER SEVERE WATCH #437 IN
EFFECT UNTIL 8 PM MDT/9 PM CDT.

LINGERING ANVIL DEBRIS FROM TONIGHTS CONVECTION WL EXIT THE ERN PRTN
OF THE CWA TUE LEAVING PARTLY CLOUDY SKIES AS SFC HIGH BUILDS INTO
THE CENTRAL PLAINS. UPSLOPE GRADIENT WL KEEP TEMPS A LITTLE
COOLER...SO WL UNDERCUT GUIDANCE BY A FEW DEGREES WITH HIGHS
REACHING INTO THE UPPER 80S MOST PLACES. A SMALL AXIS OF
WAA/MOISTURE ADVECTION DEVELOPS OVER ERN CO WITH TIME HEIGHT
CROSS SECTIONS INDICATING WEAK LIFT. WL LEAVE SLIGHT CHANCE OF TRW
IN PRTNS OF ERN CO...ALTHOUGH COVERAGE WL BE ISOLATED AT BEST. SPC
DAY 2 OUTLOOK PLACES SLIGHT RISK TO THE WEST AND SOUTH OF CHEYENNE
AND KIT CARSON COUNTIES WHERE THE BETTER LIFT AND INSTABILITY COEXIST.

H5 RIDGE SHIFTS TO THE EAST WED. A WEAK VORT/SPEED MAX WL MOVE INTO
ERN CO ALONG THE PERIPHERY OF THIS RIDGE. SFC TEMPS WL WARM UP INTO
THE LOWER 90S AS SUGGESTED BY H85 TEMPS IN THE UPPER 20S CELSIUS.
ALTHOUGH SUBSIDENCE IS EVIDENT IN TIME HEIGHT CROSS SECTIONS OVER
WRN KS INITIALLY...A SFC LOW IN THE NRN HIGH PLAINS WL PROVIDE
ENOUGH LIFT TO TRIGGER A FEW TRA...MAINLY IN THE WRN HALF OF THE RGN
WHERE FORECAST SOUNDINGS INDICATE SUFFICENT LLVL INSTABILITY.

MEDIUM RANGE MODELS ARE IN BETTER AGREEMENT IN RESPECT TO FLATTENING
THE RIDGE BY THE END OF THE WEEK AS A SYSTEM MOVES OFF THE NW COAST.
DIFFERENCES LIE IN THE STRENGTH AND MOVEMENT OF THE APPROACHING
SYSTEM. THE GFS IS MUCH QUICKER...PLACING THE H5 LOW IN SRN
CANADA...NORTH OF THE DAKOTAS SAT EVENING WHILE THE ECMWF HOLDS IT
OVR NRN ID. THE GFS APPEARS TO BE OVERDOING THE TIMING OF THIS
SYSTEM...WITH ITS SFC REFLECTION OVR THE NE PANHANDLE BY 12Z THU. A
FRONTAL BOUNDARY WILL PUSH ACROSS THE AREA BY FRI. HELD ONTO THE
SLIGHT CHANCE OF TRW FOR CONTINUITY ALTHOUGH THE LLVL MOISTURE DOES
NOT LOOK TOO IMPRESSIVE. 12Z GFS RUN BRINGS THIS FRONT BACK NORTH AS
A WARM FRONT FRI...SUGGESTING WARMER TEMPS ALONG WITH A CHANCE OF
TRW. IN FACT...LATEST MEX GUIDANCE HINTS AT 100 DEGREE TEMPS FOR
GLD. FOR NOW BUMPED TEMPS UP A COUPLE OF DEGREES...BUT HELD OFF ON
INSERTING TEMPS THIS WARM ATTM. LOOKS LIKE AN UNSETTLED PATTERN WL
CONTINUE INTO THE NEXT WEEKEND... ALTHOUGH HELD OFF ON INSERTING ANY
POPS. HOWEVER IF MODEL TRENDS CONTINUE TO ADVERTISE THIS
PATTERN...LATER SHIFTS MAY NEED TO REVISIT ADDING POPS FOR SAT/SUN.
