CLASSIC FALL WEATHER IS SLATED TO CONTINUE FOR THE REMAINDER OF THE  
WORK WEEK, WITH LITTLE IN THE WAY OF CONSEQUENTIAL WEATHER OR  
CHALLENGING ASPECTS OF THE FORECAST. THE MAJORITY OF THE WORK WEEK  
WILL FEATURE A DRY NORTHWEST FLOW PATTERN BEFORE A TRANSITION TO  
SOUTHWESTERLY FLOW IN ADVANCE OF A HIGHLY AMPLIFIED UPPER TROUGH  
PASSING THROUGH THE ROCKIES ON FRIDAY INTO SATURDAY. DRY WEATHER  
WITH TEMPERATURES RUNNING 5-10 DEGREES ABOVE NORMAL CAN BE EXPECTED  
DURING THE WORK WEEK.  
 
A STRONG PRESSURE GRADIENT WILL DEVELOP ACROSS THE PLAINS STATES  
WITH SURFACE HIGH PRESSURE ANCHORED OVER THE APPALACHIANS AND A LEE  
TROUGH FORMING OVER THE HIGH PLAINS. THIS WILL BRING SOME BREEZY  
CONDITIONS ON FRIDAY AND SATURDAY, ALONG WITH AN INCREASE IN  
MOISTURE WITH DEWPOINTS RETURNING TO THE 60S. A STRONG H85 LOW-LEVEL  
JET AND INSENTROPIC ASCENT WILL BRING OUR NEXT CHANCE AT SHOWERS AND  
THUNDERSTORMS LATE FRIDAY NIGHT INTO SATURDAY MORNING. THERE MAY BE  
A BRIEF BREAK IN CONVECTION DURING THE DAY ON SATURDAY, BUT  
INCREASING LARGE SCALE ASCENT WITH THE UPPER TROUGH AND SURFACE  
FORCING ALONG THE COLD FRONT SHOULD SPAWN WIDESPREAD SHOWERS AND  
THUNDERSTORMS SATURDAY AFTERNOON INTO THE EVENING HOURS. RAIN  
CHANCES SHOULD RAPIDLY DECREASE FOLLOWING THE FRONTAL PASSAGE, ALONG  
WITH COOLER AND DRIER AIR ADVECTING INTO THE REGION FOR SUNDAY INTO  
EARLY NEXT WEEK.
