Area forecast discussion, Feb 24, 3:05 AM CST, 16 hours 57 minutes before
TEXAS/OKLAHOMA PANHANDLES FORECAST DISCUSSION NATIONAL WEATHER SERVICE AMARILLO TX 305 AM CST THU FEB 24 2000 CURRENT ANALYSIS SHOWED A LEE TROUGH AT THE SURFACE AND A SHALLOW RIDGE ALOFT. THE RIDGE WILL WEAKEN TODAY AS AN UPPER-LEVEL STORM SYSTEM PUSHES INTO THE SOUTHWESTERN STATES. STRENGTHENING SOUTHWEST FLOW ALOFT AND LOWERING PRESSURE WILL DEEPEN THE LEE TROUGH CURRENTLY IN PLACE. AS A RESULT...SOUTHERLY GRADIENT WINDS WILL INCREASE INTO THE BREEZY OR WINDY CATEGORIES TODAY. THIS WILL ADVECT ABUNDANT LOW-LEVEL MOISTURE INTO THE EASTERN PANHANDLE THIS AFTERNOON SETTING UP A DRYLINE IN THE EASTERN ZONES. THE DRYLINE SHOULD BECOME ACTIVE LATE THIS AFTERNOON IN RESPONSE TO UPPER-LEVEL ENERGY AHEAD OF THE APPROACHING TROUGH. SOME THUNDERSTORMS SHOULD DEVELOP IN THE EASTERN ZONES AND CONTINUE THIS EVENING. THE STORMS SHOULD PUSH OUT OF THE FORECAST AREA BY MIDNIGHT AS A LARGE TROUGH ENTERS THE REGION AND A SURFACE LOW DEVELOPS IN EASTERN COLORADO. THIS LOW SHOULD PUSH INTO NORTHWEST KANSAS MOST SIMILAR TO THE ETA/ECMWF SOLUTION. THIS WILL PRODUCE A COLD FRONT WHICH SHOULD PUSH THROUGH THE FORECAST AREA FRIDAY NIGHT. THE FRONT WILL CAUSE WINDS TO INCREASE FRIDAY DURING THE MORNING AND AFTERNOON AND THERE IS A SLIGHT POSSIBILITY THAT A WIND ADVISORY WILL BE NEEDED FRIDAY. WILL MENTION WINDY CONDITIONS FRIDAY AFTERNOON. FOR THE EXTENDED PERIOD...ANOTHER FAIRLY LARGE TROUGH ENTERS THE WEST COAST ON SUNDAY SIMILAR TO THE LAST TWO UPPER-TROUGHS AND A SURFACE LOW DEVELOPS OVER THE HIGH PLAINS. AT THIS TIME...THE SYSTEM IS FORECAST TO BE FURTHER SOUTH. THIS MAY RESULT IN THE DEVELOPMENT OF THUNDERSTORMS AS THE SYSTEM APPROACHES AND THERE MAY BE A NEED TO INTRODUCE A SLIGHT CHANCE OF STORMS MONDAY AFTERNOON. WILL EVALUATE THE NEW MRF WHEN IT COMES IN AND MAKE MY DECISION THEN. OTHERWISE... AFTER A COOLER SATURDAY...EXPECT A PERSISTENT LEE TROUGH TO SET UP WARMING THINGS UP FOR SUNDA3Y AND MONDAY. PRELIM CCF... AMA 74/36 56/28 63 --0 DHT 71/31 55/23 65 --0 .AMA... TX...NONE. OK...NONE. CB
