CURRENTLY...SQUALL LINE HAS FORMED AHEAD OF DRY LINE IN WESTERN

COLORADO WITH DRY LINE THROUGH TX PANHANDLE.  CLOUDS ACROSS S MO
HAVE KEPT HEATING TO A MINIMUM THUS FAR WITH DEW POINTS ONLY IN THE
UPPER 50S TO LOW 60S.  WINDS HAVE CONTINUED TO INCREASE AT THE
SURFACE AND WERE JUST UNDER THE CRITERIA FOR WIND ADVISORY IN JLN
AREA...WHERE ADVISORY IS IN EFFECT INTO THE EVENING.  WILL LIKELY
EXTEND THIS ADVISORY SEVERAL MORE HOURS INTO THE EVENING.

WATER VAPOR IMAGERY SHOWS UPR LOW BEGINNING TO LIFT NE AND WAS NOW
LOCATED IN EASTERN COLORADO.  THIS FEATURE SHOULD CONTINUE LIFTING
NE TONIGHT INTO THE N PLAINS...WITH SFC LOW LIFTING NE INTO

TEMPERATURE RISE WITH CAA AND CLOUD COVER.

HIGH PRESSURE BUILDS INTO THE AREA AT THE SURFACE ON MONDAY NIGHT

NEED TO KEEP AN EYE ON THIS.

ANOTHER COLD FRONT LOOKS TO PUSH INTO THE AREA ON TUESDAY NIGHT AND
WEDNESDAY...WITH SOME MOISTURE CONVERGING ALONG THE FRONT...BUT
