A WARM FRONT WILL DEVELOP ACROSS THE SOUTHERN PLAINS TODAY INTO

RICH 850 MB MOISTURE HAS BEEN MOVING NORTHWARD FROM THE LONG ROUTE
OF THE RIO GRANDE. ESTIMATES ARE THAT THE EDGE OF THIS MOISTURE
COULD REACH OUR FAR SOUTHWESTERN COUNTIES THIS MORNING. A COUPLE OF
WEAK IMPULSES...ONE PRESENTLY OVER CO/NM...WILL EJECT OUT OF THE
SOUTHWEST ACROSS THE KANSAS REGION TODAY WITH SOME ISENTROPIC
UPGLIDE OCCURRING OVER OUR SOUTHWEST COUNTIES. ANY STORMS
DEVELOPING IN OUR SOUTHWESTERN COUNTIES COULD POSE A HAIL
THREAT...GIVEN STEEP MID-LEVEL LAPSE RATES...ELEVATED CAPE OF
1000-1500 J/KG...AND W-NWRLY DEEP LAYER SHEAR VECTORS OF 45 KT. A
HIGHER PROBABILITY OF SIGNIFICANT SEVERE WEATHER WILL EXIST FROM
THE TX/OK PANHANDLES INTO WESTERN OK CLOSER TO THE WARM FRONT.
WILL MAINTAIN A CHANCE OF THUNDERSTORMS OVER CENTRAL/SOUTH CENTRAL
KS FRIDAY AS THE WARM FRONT MOVES THRU WITH STRONG MOISTURE
ADVECTION. FOR SATURDAY-SATURDAY NIGHT...THE MODELS HINT AT MCS
ACTIVITY ACROSS NEBRASKA AND NORTHEAST KS NEAR AND NORTH OF THE
WARM FRONT. ANY STORMS FORMING ALONG DRYLINE WILL LIKELY BE MORE
ISOLATED AND SHOULD DIMINISH SATURDAY NIGHT AS THEY ATTEMPT TO
MOVE EASTWARD WITH CONVECTIVE INHIBITION RAPIDLY INCREASING. GUSTY
SOUTHERLY WINDS OF 15-30 MPH EXPECTED SATURDAY WITH DECENT
PRESSURE GRADIENT AND LOW LEVEL JET AXIS OVER THE AREA.

EXPECTED ON A DAILY BASIS...WITH RICH GULF MOISTURE/INSTABILITY IN
PLACE EAST OF THE DRYLINE. A FEW THUNDERSTORMS COULD FORM EACH
AFTERNOON NEAR THE DRYLINE...AND WITH NIGHTLY SOUTHERLY LOW-LEVEL
JETS...WILL MAINTAIN SOME LOW PROBABILITIES (20-40%) OF
THUNDERSTORMS IN OUR AREA. THE PATTERN COULD BECOME MORE ACTIVE IN
TERMS OF SEVERE WEATHER TOWARD MID-LATE WEEK ALTHOUGH THE MODELS

OF THE WESTERN CONUS TROUGH. TEMPERATURES WILL BE SLIGHTLY ABOVE
SEASONAL NORMS.
