LOOK FOR A GENERAL TREND OF COOLER THAN NORMAL TEMPERATURES.
A REINFORCING COLD FRONT SHOULD LEAD TO A PERIOD OF INCREASED NORTHERLY WINDS AROUND 20-25 KTS AT ALL SITES BY 12Z. WIND GUSTS COULD BE NEAR 35 KTS ESPECIALLY WITH THE INITIAL PUSH OF THE THE COLD FRONT. MODELS REMAIN IN GOOD AGREEMENT WITH EVOLUTION OF WAVE APPROACHING THE CENTRAL ROCKIES MOVING SOUTHEASTWARD INTO THE SOUTHERN PLAINS AND EVOLVING INTO A RETROGRADING CLOSED LOW. THIS SHOULD BE ENOUGH FOR A BAND OF LIGHT PRECIPITATION TO MOVE SOUTHEASTWARD ACROSS THE PANHANDLES DURING THE DAY WEDNESDAY WITH THE HIGHER PROBABILITY OF MEASURABLE PRECIPITATION BEING CONFINED TO ROUGHLY THE SOUTHWESTERN HALF OF THE AREA. NORTHWESTERLY FLOW PERSISTS INTO THE WEEKEND BETWEEN EASTERN CONUS TROUGHING AND RIDGING IN THE WEST.
