PRESSURE RIDGES IN FROM THE E. UPSLOPE FLOW HAS DIMINISHED AND SW
FLOW IS EXPECTED ACROSS CWA TODAY. ATMOSPHERE REMAINS CONDITIONALLY
UNSTABLE AND THE NAM BRINGS A WEAK UPPER WAVE ACROSS THE AREA THIS
AFTN-EVE SO WILL KEEP SOLID CHANCE POPS IN FCST. TEMPS WARM SLIGHTLY
OVER YESTERDAY SINCE A BIT MORE SUNSHINE IS EXPECTED LATE
MORNING-EARLY AFTN. UPPER HIGH BEGINS TO RETREAT W TUE ALLOWING A
SERIES OF WEAK SHORTWAVE TROUGHS TO DROP SE TOWARD CWA. IN
RESPONSE...MODELS GENERATE SOME DECENT LIFT TUE AND WED
AFTNS...ENHANCING CHANCE OF LATE DAY SHOWERS AND TSTMS. TEMPS ARE
EXPECTED TO BE SLIGHTLY ABOVE SEASONAL AVGS THROUGH MID WEEK.

UPPER TROUGH DEEPENS DAYS 4-7 AND A WEAKENING Q-STATIONARY FRONT IS

AVIATION...
PLENTY OF MOISTURE LINGERS ACROSS THE AREA THIS MORNING...BUT LOW
LEVEL UPGLIDE IS WEAKENING QUICKLY AS FLOW VEERS TO THE SOUTHWEST.
IN FACT...FLOW JUST OFF THE SFC WILL BE OUT OF THE W/NW BY
SUNRISE...RESULTING IN WEAK DOWNGLIDE. THEREFORE...DO NOT ANTICIPATE
MUCH IN THE WAY OF STRATOCU THIS MORNING...AT LEAST NOT AS MUCH AS
DURING THE TWO PREVIOUS MORNINGS. HAVE THEREFORE AVOIDED ANY MENTION
OF LOW CIGS IN THE FORECASTS IN FAVOR OF A BIT MORE EMPHASIS ON FOG/
VISBY RESTRICTIONS...WHICH SHOULD AT LEAST DECREASE TO MVFR AT ALL
TERMINALS AS HIGH LEVEL DEBRIS CLOUDS CONTINUE TO DISSIPATE. EXPECT
