FCST CHALLENGE ARE POPS TONIGHT THROUGH MONDAY.

18-19Z SFC DATA SHOWING COMPLEX PATTERN ACROSS AREA. PERSISTENT TROF
OVER PANHANDLES AND INTO SE CO IN PLACE OVER THE PAST FEW DAYS HAS
TRANSLATED TO THE SW TODAY. TSRA AGAIN FIRING ALONG THE TROF WITH
SLOW NE MOVEMENT. THESE STORMS WILL STRUGGLE TO REACH AREA, BUT WITH
SUBTLE 5H WAVE MOVING OUT OF EASTERN CO, THINK TROF MAY REACH
WESTERN AREAS LATER. VIS SAT PICS ALSO SHOWING AREAS OF ACCAS NORTH
OF EHA AND LBL AND BETWEEN DDC AND GAG WITH CAP NEARING ZERO. ADAP
PRODUCTS SHOWING GOOD 850 MB MOIST CONV, THETA ADVECTION, AND 3HR
SFC PRES FALLS COLOCATED WEST OF GCK. STRONG SFC TEMP GRADIENT
ALSO SHOWN FROM OVC AND RAIN-COOLED NW KS INTO CWA. BELIEVE
DISCONTINUITIES ALSO PRESENT WHERE MORNING STORMS DIED OUT IN GBD AND
P28 AREA. BEST LARGE SCALE DYNAMICS WILL OCCUR IN NORTHERN CWA AS
S/W ENTERS WESTERN NE AND DRAGS ACROSS NORTHERN KS.  WITH ALL THIS
IN MIND, WILL SHOTGUN POPS ACROSS AREA TONIGHT WITH BEST CHANCES IN
NORTH.

FOR MONDAY, THINK RA/TSRA WILL AGAIN LINGER INTO THE MORNING HOURS
AS THE S/W WORK EAST AND WILL PUT POPS IN ALL BUT WEST. HARD TO NAIL
DOWN HIGHS AS OUTFLOW AND RESIDUAL CLOUD COVER AS SEEN IN GLD AREA
TODAY WILL HINDER HEATING, BUT ANY AREAS WITH LITTLE CLOUDS WILL GET
NEAR TODAYS HIGHS.

FWC AND FAN KEEP LOW POPS IN FOR TUES BUT DONT SEE MUCH TO SUPPORT
THIS AND WILL KEEP CURRENT FCST GOING FOR THE MOST PART.
