Area forecast discussion, Jul 1, 3:15 PM CDT, 5 hours 42 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AMARILLO TX 315 PM CDT FRI JUL 1 2005 .DISCUSSION... PERSISTENT SHOWERS AND THUNDERSTORMS IN THE EASTERN TEXAS PANHANDLE ARE FINALLY DISSIPATING AS THE OUTFLOW THEY WERE FOCUSED ON IS MOVING WEST INTO THE MORE CAPPED ENVIRONMENT OVER THE CENTRAL PANHANDLES. TO THE WEST...THUNDERSTORMS ARE BEGINNING TO DEVELOP ALONG THE MOUNTAINS OF NM AND CO WITH COVERAGE A LITTLE MORE THAN WAS OBSERVED YESTERDAY. EXPECT THIS ACTIVITY TO SLOWLY MOVE EAST THIS EVENING ENTERING THE WESTERN COUNTIES AFTER 00Z AND MOVING ACROSS THE CWA OVERNIGHT. WILL LEAVE THE MODERATE POPS ALONE FOR TONIGHT DUE TO UNCERTAINTY IN THE COVERAGE AND LOCATION OF ANY CONVECTION BUT THIS MAY NEED TO BE INCREASED LATER. THERE MAY BE ONE MORE ROUND OF THUNDERSTORMS TOMORROW NIGHT THOUGH LESS INSTABILITY SUGGESTS COVERAGE WILL BE LESS AND THE CHANCE FOR SEVERE WILL BE DIMINISHED. MID LEVEL WARMING EARLY NEXT WEEK WILL PROBABLY SHUT OFF PRECIP CHANCES FOR OUR AREA LEAVING THE CONVECTION TO THE NORTH IN COLORADO AND KANSAS. QUESTIONS REMAIN ABOUT A FRONT MODELS SUGGEST WILL BE MOVING INTO THE AREA ON MONDAY...HOWEVER WITH THE MAIN UPPER LEVEL DYNAMICS SO FAR NORTH IT IS HARD TO SEE IT MAKING MUCH OF AN IMPACT HERE. I BROUGHT THE FRONT INTO THE NORTHERN TEXAS PANHANDLE THEN STALLED IT MONDAY DROPPING HIGHS SLIGHTLY BEHIND THE FRONT. THE FRONT SHOULD QUICKLY LIFT TO THE NORTH OF THE AREA BY TUESDAY EVEN IF ITS SOUTHWARD PROGRESSION IS AIDED BY CONVECTION FORMING ALONG THE BOUNDARY. THE REMAINDER OF THE PERIOD HAS BEEN LEFT HOT AND DRY THOUGH A NORTHWESTERLY UPPER FLOW REGIME LATE IN THE PERIOD MAY BRING MORE CHANCES FOR MOUNTAIN CONVECTION.
