NORTHWEST FLOW FOR TONIGHT WILL TRANSITION TO WESTERLY FLOW ON
TUESDAY AS THE FLOW ACROSS KANSAS LIES BETWEEN A LOW OVER THE
NORTHERN PLAINS AND A LOW OVER CENTRAL TEXAS. THE SOUTHERN
PERIPHERY OF THE NORTHERN TROUGH WILL AFFECT KANSAS AND THEN SHIFT
EAST PUTTING THE CENTRAL PLAINS IN NORTHWEST FLOW. SURFACE HIGH
PRESSURE WILL CONTINUE OVER THE CENTRAL PLAINS TONIGHT. A TROUGH
WILL MOVE INTO EASTERN COLORADO ON TUESDAY. THIS TROUGH WILL MOVE
OUT QUICKLY TUESDAY NIGHT WITH HIGH PRESSURE BUILDING INTO THE
REGION THROUGH THURSDAY.

SUBSIDENCE AND NIL POPS WILL CONTINUE THROUGH TUESDAY. TUESDAY NIGHT 
THE TROUGH WILL MOVE THROUGH THE FORECAST AREA WILL A POSSIBILITY OF 
SOME FLURRIES MAINLY OVER THE EASTERN COLORADO ZONES. FORECAST 
SOUNDINGS EVEN CAST SOME DOUBT ON THAT BASED ON MAINLY HIGH LEVEL 
RH. CONSEQUENTLY TRIMMED BACK THE AREAL COVERAGE OF THE CURRENT 
FORECAST. SUBSIDENCE TAKES OVER AGAIN FOR WEDNESDAY THROUGH THURSDAY 
NIGHT SO WILL KEEP CURRENT POPS NIL.

WINDS GET BREEZY WEDNESDAY BUT SHOULD STAY UNDER WIND ADVISORY 
CRITERIA. AT TIMES WINDS MAY TOUCH ON THE CRITERIA BUT WILL BE LOW 
END ENOUGH SO THAT AN ADVISORY WILL NOT BE NEEDED.

TEMPERATURES ARE PROBABLY THE BIGGEST ISSUE WITH THIS FORECAST. THE 
FRONT COMES INTO THE NORTHERN ZONES TUESDAY AFTERNOON LIMITING MAX 
TEMPERATURES. HIGH TEMPERATURES WED/THU WILL ONLY REACH TO ABOUT 
FREEZING WITH MIN TEMPERATURES WED NIGHT/THU NIGHT RANGING FROM 10 
TO 15. 

IN THE EXTENDED...FOLLOWED THE ECMWF SINCE THE GFS WAS CONSIDERED A 
LOW PROBABILITY SOLUTION. THE ECMWF KEEPS LOW PRESSURE OUT OF THE 
PICTURE FOR THE CENTRAL PLAINS SO DAYS 4-7 ARE DRY. NORTHWEST FLOW 
WILL CONTINUE FRIDAY WITH A RIDGE OVER THE ROCKIES MOVING EAST AND 
ZONAL FLOW FOLLOWING SUN/MON.
