AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 101 PM CDT THU MAY 27 2004 .SHORT TERM...INTERESTING DRYLINE SET UP THIS AFTERNOON AS THE FEATURE CONTINUES TO MOVE FASTER TO THE NORTH THAN THE SOUTH. AT 1 PM...IT WAS LOCATED SOUTHWEST TO NORTHEAST ACROSS WEST TEXAS AND IS ACTUALLY BECOMING MORE OF A WIND SHIFT AS PRECIPITATION TO THE WEST MOISTEN THE LOW LEVELS. SITUATION SEEMS TO BE MORE MURKY FOR TONIGHT THAN IT APPEARED TO BE YESTERDAY AFTERNOON. VIGOROUS WAVE CURRENTLY MOVING OUT OF NEW MEXICO WILL CONTINUE TOWARDS WEST CENTRAL TEXAS THIS AFTERNOON AND TONIGHT...AND CONVECTION CURRENTLY ON THE RADAR SHOULD CONTINUE TO STRENGTHEN AS LIFT IN ASSOCIATION WITH THE UPPER TROUGH MOVES THIS WAY. CAP HAS WEAKENED SIGNIFICANTLY ACROSS THE NORTHERN COUNTIES AND THIS MAY TEND TO LIMIT THE SEVERE THREAT ACROSS THE NORTH DUE TO COMPETING THUNDERSTORMS...NOW THINKING THAT THE STRONGER THUNDERSTORMS MAY BE SOUTH AND WEST WHERE CAP IS STRONGER THUS LIMITING THUNDERSTORM DEVELOPMENT SOMEWHAT. STILL NOT QUITE CLEAR HOW EVERYTHING WILL EVOLVE BUT MOST AREAS SHOULD SEE SOME RAIN. WINDS WILL GO WESTERLY LATER TONIGHT AND THINGS WILL DRY OUT. THINKING HERE IS THAT DRYLINE WILL GET A GOOD PUSH WITH THIS SYSTEM AND CAUSE WARMING CONDITIONS. WILL HAVE TO WATCH THE DRYLINE THROUGH MONDAY AS IT SLOSHES BACK AND FORTH... AND WILL CONTINUE WITH THE LOW AFTERNOON AND EVENING POPS IN THE EASTERN COUNTIES. && .LONG TERM... DID NOT MAKE MUCH CHANGE TO THE EXTENDED FORECAST. STILL LOOKS LIKE THE FLOW WILL FLATTEN OUT FOR A WHILE BEFORE GOING NORTHWESTERLY LATE IN THE PERIOD RESULTING IN THE POSSIBILITY OF OVERNIGHT THUNDERSTORMS AS WAVES COME DOWN. FOR NOW WILL KEEP THE BEST CHANCE FOR THIS ACTIVITY NORTH AND EASTERN PORTIONS OF THE FORECAST AREA. && .PRELIMINARY POINT TEMPS/POPS...
