Area forecast discussion, May 20, 5:25 PM CST, 2 hours 45 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 625 PM CDT THU MAY 20 2010 .DISCUSSION... /SEE AVIATION DISCUSSION BELOW/ && .AVIATION... COLD FRONT EXTENDED FROM JUST SOUTH OF SAN ANGELO TO DALLAS AT 23Z. A ISOLATED THUNDERSTORM POSSIBLE ALONG FRONT...BUT CHANCES LOW SO DID NOT INCLUDE THUNDER IN TAF. ONLY ADDED A CB AT KBBD. FRONT SHOULD NOT PROGRESS MUCH FARTHER SOUTH...AND SHOULD BEGIN TO MOVE BACK AS A WARM FRONT OVERNIGHT. AREA OF DENSE STRATUS OVER THE HILL COUNTRY WILL ADVECT BACK NORTH. CIGS WERE IN THE IFR TO MVFR RANGE IN THE HILL COUNTRY...WITH KERRVILLE AT 700 FT. WHILE THE NAM...GFS AND RUC MODELS ALL ADVECT MOISTURE BACK NORTH...NOT SURE THEY HAVE INDICATE THE SATURATION IN THE LOWER MOISTURE...SO WILL MOVE STRATUS REDEVELOPMENT UP A FEW HOURS...TO 3Z AT JCT...5Z AT KBBD... AND 7Z AT KSJT. BROUGHT CIGS AT KJCT AND KBBD DOWN TO IFR 3-4 HOURS AFTER STRATUS MOVES IN. OTHERWISE...STRATUS SHOULD SCATTER OUT MID/LATE MORNING ACROSS AT KABI AND KSJT...PERSISTING INTO EARLY AFTERNOON AT KBBD AND KJCT. && .PREV DISCUSSION... /ISSUED 429 PM CDT THU MAY 20 2010/ UPDATE... MADE A QUICK UPDATE TO THE POPS AND WX FOR THIS AFTERNOON INTO THE EVENING BASED ON THE LATEST SATELLITE AND OBS TRENDS. SEE DISCUSSION BELOW. DISCUSSION... WEAK FRONT HAS MADE ITS WAY DOWN TO JUST SOUTH OF SAN ANGELO AND EXTENDS EAST TO NEAR BROWNWOOD. THE FRONT ALSO EXTENDS BACK TO THE NORTHWEST INTO SOUTHWEST STERLING COUNTY. A DRYLINE EXTENDS SOUTH FROM THE FRONT ALONG THE EASTERN BORDER OF CROCKETT COUNTY. SOME AGITATED CU ARE EVIDENT ON SATELLITE ALONG THE FRONTAL BOUNDARY NEAR SAN ANGELO AND TO THE SOUTH EAST OF THE DRYLINE. THERE IS AN OUTSIDE SHOT OF AN ISOLATED STORM NEAR THE FRONT/DRYLINE INTERSECTION AND A MENTION OF THIS WAS ADDED TO THE GRIDS. I ALSO EXPANDED THE 20 POPS WESTWARD ALONG THE FRONT SOME. THE ATMOSPHERE IS PRETTY UNSTABLE SOUTH OF THE FRONT AND EAST OF THE DRYLINE...WITH CAPES IN THE 2000-3000J/KG RANGE. SHEAR IS STRONG ENOUGH FOR SUPERCELL DEVELOPMENT IF A STORM GOES. LOW LEVEL SHEAR IS WEAK...SO THE THREAT FOR A TORNADO IS PRETTY SMALL OVER W CENTRAL TX. NONETHELESS...A TORNADO WATCH IS IN EFFECT TILL 9 PM FOR BROWN AND SAN SABA COUNTIES. LACY PREV DISCUSSION... /ISSUED 228 PM CDT THU MAY 20 2010/ SHORT TERM... A VERY SLOW MOVING COLD FRONT EXTENDING SOUTHWEST FROM NORTHEAST TEXAS INTO THE CENTRAL HEARTLAND MAY PROVIDE A FOCUS FOR ISOLATED AFTERNOON AND EARLY EVENING THUNDERSTORMS...ALTHOUGH A STRONG CAP WOULD HAVE TO BE BROKEN. WILL INCLUDE A CHANCE OF THUNDERSTORMS OVER THIS AREA THIS EVENING PER EXISTING TORNADO WATCH UNLESS CONDITIONS WARRANT REMOVING OUR COUNTIES OUT OF THE WATCH BEFORE THE 9PM EXPIRATION. OTHERWISE...THE DRYLINE WILL RETREAT WEST INTO FAR WEST TEXAS AND EASTERN NEW MEXICO THROUGH TOMORROW NIGHT. 850MB THERMAL RIDGE WILL REMAIN WEST OF THE DRY LINE WITH A CHANCE OF AFTERNOON THUNDERSTORMS FIRING UP ALONG THE DRYLINE TOMORROW AFTERNOON...THESE WOULD REMAIN WEST OF THE FORECAST AREA. THE FORECAST AREA REMAINING EAST OF THE DRY LINE THROUGH THE PERIOD WILL MINIMIZE ANY FIRE WEATHER CONCERNS. A DEVELOPING LEE SIDE TROUGH WILL ELEVATE SOUTHERLY SURFACE WINDS TO 10 TO 20 MPH TOMORROW AFTERNOON. LONG TERM... AN UPPER LEVEL RIDGE WILL MOVE INTO THE AREA FRIDAY AND OVER THE WEEKEND AS A DEEPENING TROUGH MOVES INTO THE WESTERN U.S. THIS TROUGH WILL EDGE IT/S WAY INTO WEST TEXAS BY EARLY NEXT WEEK. ONE SHORTWAVE EXITS THE MAIN TROUGH TUESDAY AS ANOTHER DIVES SOUTHEAST INTO THE TROUGH TUESDAY NIGHT. THIS WILL SERVE TO MAINTAIN THE GENERAL POSITION OF THE TROUGH OVER THE WESTERN U.S. THROUGH THE MIDDLE OF THE WEEK. FROM FRIDAY NIGHT THROUGH THE WEEKEND...UPPER LEVEL RIDGING WILL BE IN CONTROL OVER WEST CENTRAL TEXAS. THIS WILL RESULT IN WARMER THAN NORMAL TEMPERATURES...AND LITTLE CHANCE FOR ANY SIGNIFICANT PRECIPITATION DUE TO WARM TEMPERATURES IN THE MID LEVELS OF THE ATMOSPHERE. BY EARLY NEXT WEEK...AS THE MAIN UPPER LEVEL TROUGH EDGES INTO WEST TEXAS...SHORTWAVES ROTATING AROUND THE TROUGH MAY COMBINE WITH DIURNAL CONVECTION FROM HIGHER TERRAIN IN WEST TEXAS TO BRING SOME THUNDERSTORM ACTIVITY INTO OUR AREA DURING THE EVENING HOURS FROM MONDAY INTO THE MIDDLE OF NEXT WEEK. HOWEVER...WILL KEEP PRECIPITATION CHANCES AT SLIGHT CHANCE OR LESS AT THIS TIME. && .PRELIMINARY POINT TEMPS/POPS...
