High winds are ongoing in the GDP Mtns and the high wind watch for Davis Mtns has been upgrade to a warning and will remain in effect thru Sunday. Question for Sunday is whether a wind advisory will be needed? Based on MSLP gradient of 4mb/70nm-100nm being co-located with 40-50kt 85h winds from the Upper to Lower Trans Pecos and subsidence on back side of trof this is a good set-up for a very windy day. It will be noticeably cooler all areas Sunday.
THIS LARGE SCALE FORCING WILL BE SUPPLEMENTED BY FRONTOGENETICAL FORCING FROM A PACIFIC COLD FRONT CURRENTLY OVER EASTERN NEW MEXICO THAT WILL MOVE THROUGH THIS EVENING. CLOUDS AND COOLER TEMPERATURES WILL KEEP MIXED LAYER INSTABILITIES ON THE ORDER OF ONLY 500-600 J/KG OFF THE CAPROCK. THE PRESSURE GRADIENT WILL TIGHTEN BEHIND A SECONDARY COLD FRONT EARLY SUNDAY MORNING.
HIGH PRESSURE. LOWS TONIGHT WILL ACTUALLY BE A LITTLE COOLER THAN LAST NIGHT.
