KS BORDER, WITH 90S OVER THE RATON MESA AND PALMER DIVIDE. UPPER
80S TO LOW 90S IN THE VALLEYS.
FOR SATURDAY, THE FLOOD THREAT WILL INCREASE. A DEEP TROUGH WILL
DEVELOP OVER THE UPPER MIDWEST WHICH WILL ALLOW A CANADIAN HIGH
PRESSURE SYSTEM TO SLIP DOWN ACROSS THE PLAINS. THIS WILL BRING
UPSLOPE TO EASTERN CO AND THIS WILL FOCUS THE MOISTURE ALONG
THE MTNS/PLAINS INTERFACE. IN ADDITION. A WEAK WAVE WILL BE
MOVING OVER THE TOP OF THE MID LEVEL RIDGE, AND THIS IN TURN
WILL BRING A BETTER CHANCE OF HEAVY RAIN ALONG THE MTNS/PLAINS
INTERFACE.
FROM SUNDAY INTO MID WEEK NEXT WEEK,, THE MID LEVEL RIDGE WILL
REMAIN OVER COLORADO. HOWEVER THE RIDGE IS EXPECTED TO FLATTEN
SOMEWHAT. THE SOUTHWESTERLY FLOW CONTINUING OVER THE SW CONUS,
THE MOISTURE PLUME WILL CONTINUE TO BE OVER THE STATE, AND THIS
WILL ALLOW FOR THE CONTINUATION OF AFTERNOON AND EVENING
SHOWERS AND STORMS OVER THE REGION. WITH THE RIDGING FLATTENING
OUT, IT WILL BE A FEW DEGREES COOLER DURING THE DAY OVER THE
