Area forecast discussion, Jul 18, 2:25 PM CST, 1 hour 15 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AMARILLO TX 325 PM CDT SAT JUL 18 2009 .DISCUSSION... THE PATTERN CONTINUES FROM THE PAST TWO DAYS. CONDITIONS ARE RIGHT FOR CONVECTION IN AREAS WITH THE MOST DAYTIME HEATING AND DISTURBANCES RIDING THE NORTHWEST FLOW THAT REMAINS IN EFFECT OVER THE PANHANDLES. FOR THIS AFTERNOON AND EVENING...STORMS ARE EXPECTED TO INITIATE IN THE WEST WHERE CLOUDS HAVE BEEN SPARSE TODAY. AT THE SAME TIME...A DISTURBANCE IS MOVING TOWARD THE AREA AND WILL HELP SPARK STORMS. LATER TONIGHT STORMS SHOULD CENTER IN THE SOUTHERN PORTIONS OF THE TEXAS PANHANDLE AND POPS WERE ADJUSTED ACCORDINGLY. ADJUSTMENTS WERE MADE MAINLY TO POPS AND QPF TO REFLECT THE TIMING OF DISTURBANCES THAT WILL BE RIDING AROUND THE RIDGE IN THE DAYS AHEAD. THE ONLY OTHER CHANGES TO THE PACKAGE WERE SOME MINOR TEMPERATURE TWEAKS. THE MAIN FEATURE OF THE EXTENDED PERIOD IS A STRONG SYSTEM THAT WILL BE MOVING PAST THE AREA NEXT WEEKEND WHICH MAY BRING SOME STORMS AND A SHIFT IN THE GENERAL PATTERN. WYNNE && .FIRE WEATHER... THE RELATIVE HUMIDITY WILL CONTINUE TO BE A LIMITING FACTOR FOR THE FIRE WEATHER CONDITIONS THROUGH THIS WEEK. MINIMUM AFTERNOON VALUES ARE EXPECTED TO REMAIN BETWEEN 25 AND 30 PERCENT. SOME AREAS ARE EXPECTED TO PICK UP MORE MOISTURE AS WELL. PASSING DISTURBANCES MAY CAUSE SOME WIND SHIFTS. IF ANY CONTROLLED BURNS ARE PLANNED...A CLOSE CHECK ON THE FORECASTS SHOULD MAINTAINED TO BETTER DETERMINE WHEN THE SYSTEMS WILL BE MOVING THROUGH THE AREA AND CAUSING WINDS TO SHIFT.
