NWS San Angelo, TX wrote its last area forecast discussion before the first event at Dec 9, 11:10 AM CST, 28 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 1110 AM CST SUN DEC 9 2007 .AVIATION... COLD FRONT AT 1700Z EXTENDED FROM SOUTH OF THE I10 CORRIDOR AND IS SHOWING LITTLE MOVEMENT TO THE SOUTH. IFR/MFR CIGS AND VSBYS WILL OCCUR ACROSS ALL OF WEST CENTRAL TEXAS THROUGH THE NEXT 24 HOURS. WITH TEMPERATURES REMAINING AT OR JUST BELOW FREEZING OVER THE BIG COUNTRY THERE IS A CHANCE OF FREEZING RAIN THROUGH THE PERIOD. TEMPERATURES SOUTH OF KABI SHOULD REMAIN JUST ABOVE FREEZING AND PRECIPITATION SHOULD REMAIN AS LIGHT RAIN AND/OR DRIZZLE. && .PREV DISCUSSION... /ISSUED 1055 AM CST SUN DEC 9 2007/ UPDATE... HAVE ISSUED A FREEZING RAIN ADVISORY FOR THE WESTERN AND NORTHERN COUNTIES OF THE BIG COUNTRY. PHONONS WITH LAW ENFORCEMENT ARE NOT REPORTING ANY ACCIDENTS...HOWEVER THEY ARE REPORTING SOME ICE ACCUMULATION ON VEHICLES. WITH TEMPERATURES HOLDING STEADY IN THE UPPER 20S AND AROUND 30...IT SHOULD BE JUST A MATTER OF TIME UNTIL WE HAVE SOME ACCUMULATION ON ELEVATED ROADWAYS. WE WILL RUN THE ADVISORY THROUGH 21Z AND MAKE A FURTHER DETERMINATION AT THAT TIME. PREV DISCUSSION... /ISSUED 942 AM CST SUN DEC 9 2007/ UPDATE... LOOKING AT CURRENT CONDITIONS AND MESHING WITH THE LATEST NAM GUIDANCE HAVE ELECTED TO KEEP TEMPERATURES NEARLY STEADY OVER THE BIG COUNTRY THROUGH THIS AFTERNOON. WITH THIS IN MIND...HAVE INTRODUCED A SLIGHT CHANCE OF FREEZING DRIZZLE OVER THE BIG COUNTRY WITH CHANCES INCREASING THIS AFTERNOON. FREEZING DRIZZLE COULD MAKE IT INTO THE NORTHERN CONCHO VALLEY IF TEMPERATURES CONTINUE TO FALL THIS AFTERNOON. WILL MONITOR CONDITIONS AND PROBABLY SEND ANOTHER UPDATE AFTER NOON. HAVE TWEAKED DEW POINTS...RH...AND WINDS ALSO. PREV DISCUSSION... /ISSUED 509 AM CST SUN DEC 9 2007/ AVIATION... COLD FRONT AT 1100Z EXTENDED FROM KBBD TO KSOA...AND REMAINS NEARLY STATIONARY. IFR/MFR CIGS AND VSBYS WILL OCCUR ALONG AND BEHIND THE FRONT THROUGH THE NEXT 24 HOURS. THERE WILL ALSO BE A CHANCE OF SHOWERS AND POSSIBLY A THUNDERSTORM TODAY ACROSS MOST OF WEST CENTRAL TEXAS. WITH TEMPERATURES DROPPING TO FREEZING AND BELOW OVER THE BIG COUNTRY THERE IS A CHANCE OF FREEZING RAIN AT KABI AFTER MIDNIGHT. PREV DISCUSSION... /ISSUED 400 AM CST SUN DEC 9 2007/ DISCUSSION... WINTRY WEATHER EPISODE IS EXPECTED BEGINNING TONIGHT...CONTINUING THROUGH MONDAY NIGHT...MAINLY FOR THE BIG COUNTRY INCLUDING THE INTERSTATE 20 CORRIDOR. A WINTER STORM WATCH WILL BE IN EFFECT BEGINNING THIS EVENING...AND IT WILL CONTINUE THROUGH MONDAY NIGHT. THIS WILL BE VERY DEPENDENT ON HOW COLD THE SURFACE CAN GET...AND WHETHER OR NOT IT WILL STAY COLD OVER THE BIG COUNTRY FOR FREEZING RAIN/DRIZZLE TO OCCUR. IT WILL ALSO DEPEND ON THE THICK WARM LAYER JUST OFF THE SURFACE. CURRENTLY...WEAK BUT PERSISTENT COLD AIR ADVECTION CONTINUES ALONG AND NORTH OF THE COLD FRONT WHICH IS STILL JUST SOUTH OF A LINE FROM WINK...TO SOUTH OF SAN ANGELO...TO BRADY...AND THEN OFF TO THE NORTHEAST INTO NORTHEASTERN TX. TEMPERATURES HAVE COOLED TO THE LOWER 30S IN THE EXTREME NORTHERN BIG COUNTRY...AND TO THE UPPER 40S ACROSS THE CONCHO VALLEY. SOUTH OF THE FRONT...TEMPERATURES ARE STILL IN THE 60S WITH DEW POINT VALUES IN THE 60S AS WELL. STRONG ISENTROPIC UPGLIDE IN SOUTHERLY FLOW AND AN ELEVATED UNSTABLE LAYER HAS RESULTED IN SHOWERS AND THUNDERSTORMS IN OKLAHOMA WHERE TEMPERATURES ARE 32 DEGREES AND COLDER...AND FREEZING RAIN IS FALLING. HAVE KEPT TEMPERATURES COLD TODAY. WITH COLD AIR ADVECTION CONTINUING THROUGH THE DAY...DO NOT EXPECT MUCH CHANGE IN TEMPERATURES FROM THE MORNING READINGS...AND THEY MAY ACTUALLY FALL SLOWLY THROUGHOUT THE DAY...WITH POSSIBLE RAINFALL AND CLOUD COVER IN PLACE. THE BEST CHANCE FOR PRECIPITATION TODAY SHOULD BE ALONG THE FRONT...AND ALONG THE EASTERN 1/3 OF THE CWA WHERE SOUTHER FLOW OVER THE TOP OF THE COLD FRONT WILL BE STRONGEST. FOR TONIGHT...AS TEMPERATURES WILL CONTINUE TO COOL AT THE SURFACE...AND PRECIP CHANCES INCREASE ACROSS THE AREA...THE CHANCE FOR FREEZING RAIN OR DRIZZLE WILL AFFECT THE BIG COUNTRY. DO NOT BELIEVE AT THIS TIME THAT TEMPERATURES WILL BE QUITE COLD ENOUGH FOR AREAS SOUTH OF A LINE FROM STERLING CITY TO BROWNWOOD. BUT IF COLD AIR ADVECTION DOES CONTINUE/STRENGTHEN TODAY...THE WATCH MAY NEED TO BE EXPANDED TO THE SOUTH. WITH THE PERSISTENCE OF THE WARM LAYER THROUGH MOST OF THE WATCH PERIOD...DO NOT THINK THAT SNOW AND/OR SLEET WILL BE AS MUCH OF A CONCERN AS THE FREEZING RAIN AS ANY ICE FALLING INTO THAT WARM LAYER SHOULD MELT...BEFORE FALLING BACK INTO SUBFREEZING TEMPERATURES AGAIN NEAR THE SURFACE. FOR AREAS SOUTH OF THE BIG COUNTRY...WE ARE EXPECTING MAINLY LIQUID PRECIPITATION. AS AN UPPER LEVEL LOW APPROACHES FROM THE WEST THROUGH THIS TIME PERIOD...SOUTHERLY FLOW ALOFT AND DOWN TO 850MB WILL CONTINUE AND/OR STRENGTHEN. THIS WILL HELP TO KEEP PRECIPITATION CHANCES IN...AND ALSO MAY RESULT IN SOME RECOVERY FROM THE COLD TEMPERATURES FOR THE SOUTHERN 2/3 OF THE CWA. HAVE THUS WARMED HIGH TEMPERATURES FROM SUNDAY/READINGS FOR MONDAY AND TUESDAY. EXPECT THIS WARMING TO BE MUCH MORE PRONOUNCED FOR AREAS SOUTH AND EAST OF A LINE FROM OZONA TO BROWNWOOD WHERE THE COLD AIR MASS MAY NOT BE AS ANCHORED AND THUS BE ABLE TO BE ERODED MUCH MORE EASILY TO THE NORTH. THINK THAT TEMPERATURES WILL HAVE A HARD TIME WARMING UP OVER THE BIG COUNTRY DUE TO THE POSSIBILITY OF FROZEN PRECIPITATION. ANOTHER COLD FRONT WILL MOVE INTO THE AREA TUESDAY NIGHT... CONTINUING THE CHANCE FOR PRECIPITATION...AND FROZEN PRECIPITATION OVER THE BIG COUNTRY. WILL HOLD OFF ON EXTENDING THE WATCH OUT THAT FAR AS CONFIDENCE IS LOW IN EXACTLY HOW COLD WE WILL BE BEHIND THIS NEXT FRONT. WE SHOULD SEE ADDITIONAL PRECIPITATION TUESDAY NIGHT INTO WEDNESDAY ASSOCIATED WITH THE INTERACTION BETWEEN THIS FRONT AND THE PASSAGE OF THE MAIN UPPER LEVEL LOW WEDNESDAY. HAVE MADE FEW CHANGES PAST WEDNESDAY FOR THE EXTENDED FORECAST. ANOTHER SHORTWAVE MOVES ACROSS THE AREA FRIDAY...SENDING ANOTHER COLD FRONT INTO THE AREA...TEMPERING THE WARMING TREND AND THIS IS REFLECTED IN THE GRIDS ALREADY. && .PRELIMINARY POINT TEMPS/POPS...
