TODAY AND THIS EVENING
PV ANOMALY IS CURRENTLY ROTATING ACROSS WY EARLY THIS MORNING, WHILE
UPSTREAM MID LEVEL PERTURBATION IS SPREADING EAST TOWARDS THE
CENTRAL PLAINS. AS THIS INITIAL WAVE APPROACHES BEFORE SUNRISE, THE
WARM FRONT OVER SOUTHEAST KS LIFTS BACK NORTHWARD INTO THE AREA,
INCREASING SOUTHEAST WINDS FROM 15-25 MPH ALONG WITH LOW STRATUS.
THE DEPTH AND LONGEVITY OF THE STRATUS LINGERING INTO THE AFTERNOON
REMAINS THE MAIN DETERRENT IN MORE ROBUST UPDRAFTS BY THE MID
AFTERNOON. A STRONG COLD FRONT IS PROGGED TO SWEEP EASTERN KANSAS
AFTER 1 PM WHEN THE CAPPING INVERSION ERODES. AND WHILE THERE IS
CONSISTENCY AMONG CAM GUIDANCE OF THE FRONTAL BOUNDARY'S LOCATION
AND NARROW LINE OF CONVECTION FORMING ALONG IT, DIFFERENCES IN
UPDRAFT HELICITY AND OVERALL SEVERITY IN STORMS IS UNCLEAR. BY
AROUND 21Z, IF WE CAN OBSERVE SOME CLEARING PRIOR TO THE FRONT,
FORECAST CAPE MAXIMIZES AROUND 3000 J/KG WHILE BULK 0-6 KM SHEAR IS
30-40 KTS. SHEAR VECTORS ARE MOSTLY PARALLEL TO THE BOUNDARY,
BOLSTERING CONFIDENCE IN MAINLY A LARGE HAIL AND DAMAGING WIND
EVENT. GOOD LOW LEVEL SHEAR/CURVATURE NOTED ON HODOGRAPHS AHEAD OF
THIS LINE HOWEVER SUGGEST A BRIEF TORNADO OR TWO CANNOT BE RULED
OUT. THE LINE OF STORMS SHOULD CLEAR TO THE EAST BY 02Z.
SATURDAY - TUESDAY
COOL HIGH PRESSURE SETTLES SFC WINDS BY SATURDAY MORNING, ALLOWING
LOWS TO FALL INTO THE LOW 30S. HIGH TEMPS QUICKLY REBOUND TO NEAR
NORMAL IN THE 60S FROM SUNDAY ONWARD. A STATIONARY BOUNDARY SETS UP
OVER THE STATE ON MONDAY, LENDING TO BELOW AVERAGE CONFIDENCE IN
HIGHS MONDAY RANGING FROM THE LOW 50S NORTH TO MIDDLE 60S SOUTH.
STILL MONITORING A PROGRESSIVE OPEN WAVE BRINGING LIGHT PRECIP EARLY
TUESDAY MORNING AS THE FRONT LIFTS TO THE KS/NE BORDER. NBM PROBS
ARE OVERALL ON THE LOW SIDE FOR QPF (LESS THAN 0.05 INCHES) WHILE
SNOW PROBS ARE LESS THAN 20% AND GENERALLY NORTH OF I-70.
WEDNESDAY - FRIDAY
UPPER PATTERN TURNS ACTIVE AGAIN AS A NORTHERN STREAM WAVE FORCES
