THE SOUTHERN UPPER LEVEL LOW WAS PUSHING TOWARDS THE TEXAS PANHANDLE
THIS MORNING. AZTEC PROFILER SHOWED THE MID-LEVEL TROUGH PASSAGE JUST
BEFORE MIDNIGHT THERE...WITH THE UPPER FLOW BACKING TO NORTH
OVERNIGHT. THE ASSOCIATED SURFACE FRONT NEVER PUSHED MUCH FURTHER
NORTH THAN THE NEW MEXICO-COLORADO STATE LINE. DURANGO DISPATCH

THE MISSISSIPPI VALLEY.
THE BOUNDARY LAYER REMAINS QUITE MOIST THIS MORNING AND WEAK COLD
ADVECTION ALOFT WILL ADD TO THE INSTABILITY TODAY. CONVECTIVE SHOWERS
WILL INCREASE IN AREAL COVERAGE TODAY...AND TONIGHT...WITH LIGHT
ACCUMULATIONS IN THE MOUNTAINS FAVORING THE CONTINENTAL DIVIDE.

POSITIVELY TILTED RIDGE AXIS BUILDS INTO THE ROCKIES. THIS WILL
BRING A DRYING TREND. WARM AND DRY ADVECTION ALOFT THURSDAY NIGHT
WILL ALLOW FOR GOOD RADIATIONAL COOLING FOR COLD OVERNIGHT LOW
TEMPERATURES.
