DISCUSSION...
VERY LIGHT RADAR ECHOES OVER THE NORTHWESTERN TEXAS PANHANDLE AT
THIS TIME MAY DEPICT FLURRIES/VERY LIGHT SNOW SHOWERS. HOWEVER...NO
MEANINGFUL PRECIPITATION IS EXPECTED ALL INDICATIONS SUGGEST THIS
ACTIVITY WILL DISSIPATE BY SUNRISE LEAVING PARTLY CLOUDY SKIES.
OTHERWISE...BENIGN WEATHER IS ANTICIPATED THIS WEEK.

DRY NORTHWESTERLY FLOW ALOFT IS EXPECTED TO PERSIST THIS WEEK. A WEAK
POSITIVELY TILTED SHORTWAVE TROUGH WILL PROGRESS THROUGH THIS FLOW
OVER WEST TEXAS LATE TONIGHT/EARLY TUESDAY BUT NO MORE THAN
SCATTERED PASSING CLOUDS ARE CURRENTLY INDICATED...ALTHOUGH CAN NOT
RULE OUT ADDITIONAL FLURRIES/LIGHT SHOWERS HAS SEEN TONIGHT. IN
GENERAL...HOWEVER...HEIGHTS/THICKNESSES WILL BE ON THE INCREASE THIS
WEEK AS THE PATTERN USHERS IN SEVERAL WEAK FRONTS OF MILD PACIFIC
ORIGINS. THIS WILL YIELD A GRADUAL WARM UP TOWARD 10+ DEGREES ABOVE
SEASONAL AVERAGE TEMPERATURES BY THE END OF THE WORK WEEK.

MEDIUM RANGE GUIDANCE CONTINUES TO BE INCONSISTENT IN HANDLING
POTENTIAL FOR THE NEXT NOTABLE COLD FRONT...AND THIS INTRODUCES SOME
UNCERTAINTY FOR TEMPERATURES THIS WEEKEND. THE STRONGEST SIGNAL IS NOW
INDICATED BY THE GFS WITH A SIMILAR TREND IN THE MOST RECENT ECMWF FOR
AN INTRUSION OF COLD AIR OVER THE CENTRAL/SOUTHERN PLAINS BY LATE
SATURDAY AND/OR SUNDAY. THESE TRENDS WILL BE MONITORED.
