PLENTY OF DIURNAL CU OVERHEAD THIS AFTERNOON...BUT THEY ARE STRUGGLING TO PRODUCE MUCH IF ANY SHOWERS. HAVE TRIMMED POP BACK EVEN FURTHER AS ANY SHOWERS WILL BE FAIRLY UNLIKELY AT THIS POINT.

DAYTIME HEATING WILL LEAD TO MORE DIURNAL CU...THOUGH LESS WIDESPREAD THAN TODAY. NOT EXPECTING MUCH IN THE WAY OF PCPN...THOUGH THE HIGHER TERRAIN COULD SQUEEZE OUT A BRIEF SHOWER AROUND AND JUST AFTER PEAK HEATING. WILL BE A WARMER DAY ACROSS THE AREA...WITH WARMER LOCALES REACHING TO NEAR 80. CLOUDS CLEAR AGAIN OVERNIGHT...WITH MORE VALLEY FOG IN FAVORED LOCATIONS.

HIGH PRESSURE WILL SETTLE SOUTH OF NEW ENGLAND FOR THE BEGINNING OF THE WORK WEEK. THIS WILL ALLOW FOR A SOUTH TO SOUTHWEST FLOW TO SET UP ACROSS THE REGION...ALLOWING FOR WARMER TEMPERATURES TO ENTER THE REGION. LOOK FOR HIGHS TO CLIMB INTO THE LOWER 80S INLAND TOMORROW...WITH STILL 70S ALONG THE COAST AND UP IN THE HIGHER TERRAIN. WARM AIR ADVECTION WILL CONTINUE IN THE LOWER LAYERS ON TUESDAY...WITH WIDESPREAD 80S AWAY FROMT THE COASTLINE. IT WILL STILL ONLY BE IN THE 70S ALONG THE BEACHES...BUT IT WILL FEEL MILDER WITH INCREASING DEW POINTS. A REPEAT PERFORMANCE IS EXPECTED AGAIN ON WEDNESDAY WITH SOUTH SOUTHWESTERLY WINDS ALONG AND OUT AHEAD OF AN APPROACHING COLD FRONT. SHOWERS WILL DEVELOP LATER IN THE DAY WEDNESDAY...HOWEVER THERE STILL CONTINUES TO BE TIMING DIFFERENCES WITH THE MODELS. A FEW SCATTERED SHOWERS AND POSSIBLY A THUNDERSTORM WILL LAST INTO EARLY THURSDAY. THEREAFTER...MORE SUNSHINE WITH HIGH PRESSURE WILL BE ENTERING THE REGION.
