AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE AMARILLO TX 1151 PM CST TUE DEC 9 2014 .AVIATION... FOR THE 06Z TAFS...LOW CLOUDS CONTINUE TO BUILD NORTHWARD INTO THE SOUTHERN TEXAS PANHANDLE...WHILE LOW CLOUDS AND FOG ARE DEVELOPING ACROSS THE FAR EASTERN PANHANDLES. FEEL CONFIDENT THAT THESE SHOULD EVENTUALLY OVERSPREAD THE TAF SITES OVER THE NEXT FEW HOURS...LEADING TO IFR CEILINGS. VISIBILITY COULD BE REDUCED DUE TO BR...BUT DO NOT THINK DENSE FOG WILL AFFECT THE TERMINALS BEFORE WEDNESDAY MORNING. AT KAMA...EXPECT MVFR CEILINGS TO PERSIST AT LEAST THROUGH 18Z...BUT COULD LINGER INTO THE AFTERNOON. AT KDHT AND KGUY...LOW CLOUDS ARE LIKELY TO GIVE WAY TO VFR CONDITIONS BY LATE MORNING. NF && .PREV DISCUSSION... /ISSUED 550 PM CST TUE DEC 9 2014/ AVIATION... 00Z TAFS...VFR CONDITIONS THIS EVENING WILL GIVE WAY TO DETERIORATING CONDITIONS OVERNIGHT AS WEAK BUT MOIST LOW-LEVEL SOUTHERLY FLOW IS EXPECTED TO LEAD TO STRATUS AND FOG DEVELOPMENT. CIGS/VSBYS WILL LIKELY DROP TO IFR/LIFR LEVELS AFTER 06Z...AND PERSIST INTO WEDNESDAY MORNING. A WEAK WIND SHIFT TO THE NORTHWEST USHERING IN DRIER AIR...ALONG WITH DAYTIME MIXING...WILL BRING IMPROVING CONDITIONS FROM NORTHWEST TO SOUTHEAST MID TO LATE WEDNESDAY MORNING. KAMA WILL LIKELY BE THE LAST TO SEE A RETURN TO VFR CONDITIONS...WHICH SHOULD OCCUR AROUND 18Z. KB PREV DISCUSSION... /ISSUED 310 PM CST TUE DEC 9 2014/ DISCUSSION... WATER VAPOR/RAP ANALYSIS SHOWS SHORTWAVE RIDGING OVER THE AREA THIS AFTERNOON WITH THE NEXT SYSTEM TO AFFECT THE AREA LOCATED OVER ARIZONA. THIS RELATIVELY WEAK SOUTHERN STREAM SHORTWAVE WILL RESULT IN STRENGTHENING LEE TROUGH AND INCREASING SOUTHERLY MOIST LOW LEVEL FLOW. LOW STRATUS AND FOG WILL LIKELY FORM AFTER MIDNIGHT AND PERSIST THROUGH AT LEAST EARLY MORNING. BY AFTERNOON AT LEAST THE WESTERN HALF OF THE OKLAHOMA AND TEXAS PANHANDLES SHOULD SEE PARTIAL CLEARING. DRY MID LEVELS SHOULD PRECLUDE PRECIPITATION CHANCES ALTHOUGH DEPTH OF THE MOIST LAYER MAY BE SUFFICIENT IN THE FAR SOUTHEAST FOR SOME DRIZZLE. MEASURABLE PRECIPITATION APPEARS UNLIKELY. UPPER LEVEL RIDGING BUILDS IN BY LATE THURSDAY THROUGH AT LEAST EARLY SATURDAY BEFORE HEIGHTS BEGIN TO FALL AHEAD OF APPROACHING UPPER LEVEL TROUGH. PRECEDING THIS SYSTEM ON FRIDAY AND SATURDAY TEMPERATURES SHOULD WARM TO THE UPPER 60S TO LOWER 70S WHICH IS ABOUT 20 DEGREES ABOVE NORMAL FOR DECEMBER. MODELS HAVE NOT BEEN VERY CONSISTENT WITH HANDLING THE SYSTEM THAT WILL IMPACT THE REGION BY THE LATTER PART OF THE WEEKEND INTO EARLY NEXT WEEK. INITIAL CONCERNS ARE POTENTIAL FOR STRONG SOUTHERLY WINDS AHEAD OF THE SYSTEM AS LEE TROUGH STRENGTHENS AND SURFACE PRESSURE GRADIENT TIGHTENS SIGNIFICANTLY. 00Z RUNS SEEMED TO BE FURTHER NORTH COMPARED TO THE 12Z RUNS WHICH HAVE SHIFTED THE TRACK OF THE CLOSED LOW FURTHER SOUTH AGAIN. TRENDS YESTERDAY SUGGESTED A MORE PROGRESSIVE/OPEN SYSTEM WITH PERHAPS A DRIER FORECAST. OPERATIONAL GFS...ITS ENSEMBLES...AND ECMWF ARE ALL CLUSTERED FAIRLY CLOSE TOGETHER NOW. GIVEN THE INHERENT NATURE OF THESE SOUTHERN STREAM SYSTEMS...UNCERTAINTY REMAINS RATHER HIGH ON PRECIPITATION AMOUNTS AND TYPE. THE 12Z GFS AND ECMWF HAVE INCREASED QPF CONSIDERABLY OVER THE EASTERN PORTION OF THE AREA. WITH THE CURRENT INDICATED TRACK...TEMPERATURES WOULD BE WARM ENOUGH FOR ALL RAIN EXCEPT IN THE NORTHWEST HALF WHERE A CHANGE OVER TO SNOW WOULD BE POSSIBLE SUNDAY NIGHT. PRECIPITATION MAY LINGER INTO EARLY MONDAY FOR AT LEAST THE NORTHERN HALF. POST FRONTAL WINDS LATE SUNDAY INTO MONDAY MAY NEED TO BE ADJUSTED UPWARD IN LATER FORECASTS.
