DISCUSSION
KEY MESSAGE 1...
SURFACE ANALYSIS THIS MORNING DEPICTS A FRONTAL BOUNDARY DRAPED
NORTH OF THE FORECAST AREA THAT IS PROGGED TO SLIP DOWN FROM THE
NORTHEAST DURING THE DAY TODAY. THE LACK OF MOISTURE ASSOCIATED
WITH THE BOUNDARY AND STRONG UPPER LEVEL RIDGING ALOFT WILL
MITIGATE ANY MEASURABLE PRECIPITATION WITH THIS FEATURE AS IT
REMAINS NESTLED NEARBY.
AS THE INFLUENCE OF THE UPPER RIDGE GRADUALLY LESSENS THIS
WEEK, A FEW SUBTLETIES TO THE FORECAST WILL ENSUE. WITH THE
FRONTAL BOUNDARY NEARBY TODAY INTO WEDNESDAY, AN INCREASE IN
CLOUD COVERAGE WILL TAKE SHAPE. ONCE THE BOUNDARY RETREATS TO
THE NORTH AS A WARM FRONT, THE SURFACE HIGH WILL REGAIN CONTROL
FOR THE END OF THE WORK WEEK AND PROMOTE AMPLE SUNSHINE ONCE
MORE. ADDITIONALLY, POST-FRONTAL SOUTHWESTERLY FLOW WILL
ENCOURAGE A SLIGHT WARM UP THAT WILL MITIGATE ANY CONCERN FOR
FROST/FREEZE MESSAGING, AS OVERNIGHT LOWS GROW MILDER WITHIN
THIS REGIME. THE RIDGE BREAKS DOWN FURTHER INTO THE WEEKEND,
WITH A PATTERN CHANGE PROGGED TO TAKE SHAPE BEGINNING ON
HALLOWEEN.
KEY MESSAGE 2...
THE PREDOMINANT STRETCH OF DRY WEATHER ROUNDING OUT THE SECOND
HALF OF OCTOBER COMES TO A CONCLUSION THIS WEEKEND AS
STRENGTHENING LOW PRESSURE ACROSS THE WESTERN US TAKES AIM FOR
THE OHIO VALLEY. THIS WILL REINTRODUCE MEASURABLE PRECIPITATION
BACK INTO THE FORECAST AS EARLY AS LATE SATURDAY NIGHT INTO
SUNDAY MORNING, AND MAINTAINING UNSETTLED WEATHER THROUGH THE
REMAINDER OF THE EXTENDED FORECAST PERIOD. TIMING AND EXTENT OF
THIS APPROACHING DISTURBANCE WILL CONTINUE TO BE HASHED OUT AS
WE GET CLOSER TO THE WEEKEND TIMEFRAME.
AVIATION /09Z TUESDAY THROUGH SATURDAY/
VFR CONDITIONS REMAIN FAVORED THROUGH THE MAJORITY OF THE TAF

THE DAY.
