Surface Analysis

00 UTC SURFACE ANALYSIS SHOWS A 1006 MB SURFACE LOW ABOUT NEAR TEXARKANA. THIS SURFACE LOW HAS RETROGRADED THROUGHOUT THE DAY IN THIS PECULIAR AND UNUSUAL PATTERN. AN EAST-WEST PRESSURE TROF IS ANALYZED FROM THE SURFACE LOW TO JUST NORTH OF OUR FORECAST AREA. I HESITATE TO CALL THIS A WARM FRONT DUE TO THE OVERALL LACK OF CHANGE OF AIRMASS BETWEEN THE GULF COASTAL AREAS AND NORTHERN MISS/AL...THUS FEEL THE SLIGHT ENE-ESE WIND SHIFT IN THE AREA IS BETTER DEFINED AS A PRESSURE TROF. A LARGE 1030 MB RIDGE WAS BUILDING IN OVER SOUTHERN QUEBEC.
