A DEEP AND ELONGATED UPPER TROUGH CURRENTLY EXTENDS FROM SOUTHERN
ARIZONA, NORTHWARD INTO SOUTHERN ALBERTA CANADA. AN UPPER RIDGE
AXIS EXISTS FURTHER DOWNSTREAM FROM EAST TEXAS NORTH INTO THE
WESTERN GREAT LAKES. SOUTH SOUTHWEST FLOW ALOFT RESIDES IN
BETWEEN THESE FEATURES FROM EASTERN COLORADO NORTHWARD ACROSS
WESTERN NEBRASKA INTO THE NORTHERN PLAINS.
TONIGHT, THE UPPER TROUGH AXIS WILL ADVANCE EASTWARD TO THE TEXAS
PANHANDLE, EASTERN WYOMING AND CENTRAL MONTANA BY 12Z SUNDAY.
SURFACE LOW PRESSURE WILL BEGIN ALONG NORTHEAST COLORADO THROUGH
THE NEBRASKA PANHANDLE EARLY EVENING, WITH THE FRONTAL BOUNDARY
MOVING SLOWLY EASTWARD OVERNIGHT WITH AN AMPLIFIED SSW FLOW
ALOFT. SCATTERED TO NUMEROUS SHOWER AND THUNDERSTORM DEVELOPMENT
IS EXPECTED ACROSS THE WEST, WITH EASTWARD DEVELOPMENT
OVERNIGHT. LONG, STRAIGHT HODOGRAPHS NEAR THE FRONTAL BOUNDARY
COULD SUPPORT A FEW STRONG STORMS THIS EVENING NEAR AND WEST OF
HIGHWAY 83. BENEFICIAL RAINFALL EXPECTED FOR MUCH OF WESTERN
NEBRASKA, WITH PWAT VALUES EXCEEDING THE 90TH PERCENTILE CLIMO

SURFACE LOW AND FRONTAL BOUNDARY GRADUALLY MOVES EAST. PWAT VALUES
REMAIN ABOVE THE 90TH PERCENTILE SUNDAY AFTERNOON. EFFICIENT
RAINFALL WILL CONTINUE, WITH MUCH OF THE AREA SEEING BENEFICIAL
ACCUMULATIONS BY THE TIME THE SYSTEM BEGINS TO EXIT THE AREA LATER
