HIGH PRESSURE CENTERING OVER THE AREA THE CULPRIT...BUT AXIS WILL SHIFT EAST TONIGHT ALLOWING A MODERATE SOUTHWEST FLOW ALOFT TO DEVELOP FOR MONDAY IN ADVANCE OF AN UPPER LOW THAT WILL PASS THROUGH THE AREA MONDAY NIGHT AND TUESDAY. SAID LOW HAS FINALLY TAPPED MID LEVEL MOISTURE TODAY AND IS BECOMING MORE APPARENT ON SATELLITE PRODUCTS. BAND OF CLOUDS FORMING ON THE NORTHEASTERN PERIPHERY WILL CONTINUE TO SPREAD NORTH INTO THE AREA TONIGHT AND WILL LIMIT COOLING AS SUCH.
