MESOSCALE UPDATE...
THUNDERSTORMS FORMING IN THE LEE OF THE ROCKIES WILL PROGRESS
EASTWARD INTO EXTREME SOUTHWEST KANSAS BY 7-8 PM. AHEAD OF THE
STORMS THERE WAS A STRONG SURGE OF LOW LEVEL MOISTURE WITH
RAPID DESTABILIZATION OCCURRING. A LOW LEVEL JET WILL CONTINUE
TO TRANSPORT MOISTURE INTO SOUTHWEST KANSAS AHEAD OF THE
DEVELOPING STORMS. GIVEN THE LOW LEVEL SOUTHERLIES, MODERATE MID
LEVEL WESTERLIES AND FAVORABLE UPPER LEVEL SHEAR, STORM
ORGANIZATION INTO A CLUSTER IS LIKELY DURING THE EVENING. THERE
IS HIGH CONFIDENCE IN STORM LONGEVITY GIVEN MCS MAINTENANCE
PARAMETER VALUES OF 90+ AND CRAVEN/BROOKS SIGNIFICANT SEVERE
VALUES OF 30+. THE MAIN CONCERNS ARE WIND GUSTS TO 70 MPH AND
HAIL TO 1.5". GIVEN THAT STORM CLUSTERS FORMING ON THE RATON
MESA TEND TO REMAIN NEAR OR JUST NORTH OF THE 37TH PARALLEL AND
SOUTHWARD, SEVERE WEATHER NORTH OF GARDEN CITY AND DODGE CITY
IS UNLIKELY. ALTHOUGH THE SHEAR AND INSTABILITY PROFILES ARE
FAVORABLE FOR SUPERCELLS WITH LARGER HAIL, BY THE TIME THE
STORMS MOVE INTO SOUTHWEST KANSAS THIS EVENING WE EXPECT UPSCALE
GROWTH TO HAVE RESULTED IN STORM CLUSTERS INSTEAD OF
INDIVIDUAL, ISOLATED STORMS. THIS WILL LIMIT HAIL SIZE TO BELOW
2" AND LIKELY PRECLUDE SIGNIFICANT TORNADOES.

THE SYNOPTIC PATTERN ALOFT IS DOMINATED BY A DEEP TROUGH IN THE FAR
NORTHERN PORTION OF THE CONUS WITH MORE ZONAL FLOW OVERHEAD OF THE
FORECAST AREA. THIS PATTERN STRETCHES DOWN TO THE SURFACE WITH A
WEAK SURFACE HIGH IMPOSING OVER THE CWA. THIS HAS HELPED KEEP WINDS
LIGHT AFTER A BREEZIER YESTERDAY. HIGHS TODAY ARE FORECAST IN THE
UPPER 80S/LOWER 90S WITH THE FOCUS BEING ON THE STORM POTENTIAL
ARRIVING TONIGHT.
CAMS HAVE BEEN ALL OVER THE PLACE REGARDING THE CONVECTION TONIGHT
IN INTENSITY, ORGANIZATION, AND COVERAGE. MODELED SOUNDINGS FROM
THE NAM HAVE CAPE VALUES OF AROUND 2000 J/KG AND DEEP LAYER SHEAR AT
AROUND 35 KTS. MOST OF THE CAMS HAVE STORMS INITIATING IN EASTERN
COLORADO IN THE EARLY EVENING AND ORGANIZING INTO A MCS REPRESENTING
A MORE LINEAR STRUCTURE AS IT MOVES INTO KANSAS AROUND 7-8 PM. FROM
THERE, TREMENDOUS DIVERGENCE IS PRESENT BETWEEN RUNS. SOME HAVE IT
DIVING SOUTH QUICKLY LIKE THE RRFS, SOME HAVE AGGRESSIVE EXPANSIONS
AND ENCOMPASSING MOST OF THE AREA LIKE THE HRRR, AND THE NAMNST
KEEPS THE STORMS UNORGANIZED AND COLLAPSING SHORTLY AFTER ENTERING
KANSAS. AS A RESULT, PREDICTING A PRECISE PATHING IS QUITE
DIFFICULT, WITH AN AGGREGATE BEING THE CURRENT FORECAST. THIS BEING
AT LEAST LOOSELY ORGANIZED CONVECTION QUICKLY BECOMING LINEAR AND
STRETCHING EAST INTO THE FORECAST UNTIL AROUND HIGHWAYS 83 AND 283
BY AROUND 10 PM. BY THAT POINT, IT WILL BEGIN TO WEAK AND DIVE
SOUTHEASTWARD TOWARDS THE OKLAHOMA BORDER. INITIALLY IF STRONG
INDIVIDUAL CELLS CAN FORM AND MATURE EARLY IN THE EVENT, ALL
HAZARDS MAY BE POSSIBLE IN FAR SW KANSAS ALBEIT OF VERY MARGINAL
INTENSITY. HOWEVER, IT IS EXPECTED THAT THE PRIMARILY THREAT
WILL QUICKLY BECOME STRONG WINDS OF UP TO 70 MPH. IT IS VERY
CONTINGENT ON HOW STRONG THE STORMS GET AND HOW WELL THEY CAN
ORGANIZE, BUT THERE SEEMS TO BE JUST ENOUGH INGREDIENTS IN THE
FORECASTED ENVIRONMENT TO SUPPORT AN ORGANIZED SYSTEM OF THAT
STRENGTH.
SATURDAY'S CONVECTION FORECAST SEEMS ALMOST AS MESSY AFTER HIGHS
FORECASTED IN THE 90S AND APPROACHING 100 NEAR THE OKLAHOMA BORDER.
MODELS HAVE A BOUNDARY STALLING FROM ROUGHLY THE TEXAS PANHANDLE TO
SOUTH CENTRAL KANSAS. EXACT PLACEMENT OF THE BOUNDARY WILL DETERMINE
HOW MUCH PRECIPITATION SW KANSAS SEES. CURRENT CAM RUNS HAVE SOME
STORMS DETACHING AND MOVING NORTH OF THE BOUNDARY AND IMPACTING THE
AREA, BUT THAT WOULD ALSO BE IN THE SIGNIFICANTLY LESS FAVORABLE
ENVIRONMENT WHERE THEY MAY BE SUB-SEVERE AND SHORT-LIVED. WITH MODEST
CAPE AND SHEAR VALUES SIMILAR TO FRIDAY, THE BEST CHANCE FOR SEVERE
STORMS ARE ONES THAT ARE ABLE TO STAY IN THE MOVE FAVORABLE AIR NEAR
BARBER COUNTY. THIS MAY HAPPEN AGAIN AROUND 7-8 PM ALTHOUGH CAMS
VARY FROM AROUND 5-9 PM FOR INITIATION. AGAIN WINDS FROM THE
STRONGEST STORMS ARE THE PRIMARY THREAT WITH POTENTIALLY SEVERE
WINDS.
BEHIND A COLD FRONT, SUNDAY WILL BE PARTICULARLY PLEASANT WITH HIGHS
ONLY IN THE 70S. ENSEMBLES HOLD AROUND A 20-30% CHANCE FOR BENIGN
PRECIPITATION IN FAR SW KANSAS ON SUNDAY. THE FIRST HALF OF THE WEEK
WILL SHARPLY WARM BACK UP WITH HIGHS WEDNESDAY FORECAST TO BE A
RETURN OF TRIPLE DIGITS BEFORE EASING BACK DOWN INTO THE 90S TOWARDS
THE END OF THE WEEK. ENSEMBLES SEEM TO HOLD ONTO A WEAK
PRECIPITATION SIGNAL ON TUESDAY, BUT WITH THE AMPLE UNCERTAINTY IT
IS MERELY SOMETHING TO BE AWARE OF. WEDNESDAY WITH THE HOT
TEMPERATURES HAS FORECAST RELATIVE HUMIDITIES BEING VERY DRY WITH
SINGLE DIGIT PERCENTS WEST OF HIGHWAY 83. WINDS CURRENTLY ARE
FORECAST TO REMAIN BELOW 20 MPH AND IS EXPECTED TO QUELL MOST OF THE
FIRE WEATHER RISK ALTHOUGH BASIC PRECAUTIONS MAY STILL BE
NECESSARY.

01-03Z. OTHERWISE, EXPECT MAINLY VFR CONDITIONS TO PREVAIL
THROUGH EARLY SATURDAY. SOUTHERLY WINDS AROUND 10 TO 20KT WITH
GUSTS UP TO 25KT ARE EXPECTED TO PERSIST THROUGH EARLY SATURDAY
