133 AM EDT MON MAY 23 2016 Dry high pressure builds into our region from the Mississippi and Ohio valleys early this week as low pressure lingers over the Mid-Atlantic. On Monday, the center of the coastal H5 closed low will drift over the western Atlantic, but leave cyclonic flow across the Atlantic states. The circulation around the low should result in greater cloud cover north of I-40, with the rest the CWA under mostly to partly sunny conditions.
250 PM EDT FRI MAY 6 2016 LOW PRESSURE WILL CONTINUE TO IMPACT THE REGION TODAY BEFORE WEAKENING AND MOVING AWAY FROM THE AREA TONIGHT INTO SATURDAY.
NEXT TROF AXIS STILL NORTH OF THE REGION ACRS SC AND HEADED SOUTHWARD. BUT STILL SUNNY SKIES WITH JUST A FEW HIGH CLOUDS AND TEMPS SLOWLY PUSHING INTO THE LOWER/MIDDLE 70S. NEXT TROF TO ROTATE AROUND THE UPPER LOW PARKED OFF THE CAROLINAS AND WILL PUSH THROUGH SE GA AND INTO THE COASTAL WATERS OVERNIGHT. UPPER LEVEL TROF PUSHES INTO THE WRN ATLC AND HIGH PRESSURE BUILDS IN FROM THE WEST AT THE SURFACE AND ALOFT AND EXPECT MAX TEMPS TO REBOUND CLOSER TO NORMAL VALUES IN THE LOWER 80S INLAND AND UPPER 70S ALONG THE COAST.
THE UPPER LOW WILL DRIFT NWD AND HOVER OVER THE EASTERN HALF OF THE STATE TONIGHT BEFORE FILLING AND GETTING KICKED OUT TO SEA BY AN ANOMALOUS TROUGH MOVING IN FROM THE WNW ON SAT.

THE UPPER LOW TO OUR EAST RESPONSIBLE FOR THE COOLER THAN NORMAL WEATHER CONTINUES TO SHIFT NE UP THE E COAST, WITH ONLY A FEW CLOUDS PINWHEELING AROUND THE WESTERN EDGE OF THE DEPARTING SYSTEM. OTHERWISE, AFTERNOON HIGHS WILL TOP OUT IN THE LOWER TO MIDDLE 70S THIS AFTERNOON UNDER MOSTLY SUNNY SKIES. HIGH PRESSURE HAD RESULTED IN 5-15 KT WINDS FROM THE NORTH. THE WINDS SHOULD BECOME LIGHT FROM THE NORTH AS THE LOWER CLOUDS FADE.
HELD UP BY A BLOCKING SYSTEM OFF THE MID ATLANTIC COASTLINE. STRONG SOUTHERLY MID LEVEL WINDS WRAPPING AROUND THE LOW AND ELEVATED MOISTURE IS PROVIDING AN ENHANCED V PROFILE WITH DECENT LINEAR SHEAR THIS AFTERNOON. THE UPPER LOW WILL CROSS SOUTHEAST UTAH INTO NORTHWEST COLORADO SATURDAY WITH THE COOLER AIR ALOFT PROVIDING INSTABILITY AND DROPPING SNOW LEVELS DOWN TO NEAR 9000 FEET. AS THE LOW TRUDGES INTO NORTHEAST COLORADO THE DEFORMATION ZONE IS FOCUSED NORTH OF OUR BORDER SATURDAY NIGHT SO AGAIN A RATHER DISTINCT DOWN TURN IN PRECIPITATION IS ANTICIPATED. THE COOL DOWN WILL BE RATHER NOTICEABLE AS WELL WITH HIGHS ON SATURDAY EXPECTED TO BE SOME 15 TO 20 DEGREES COOLER THAN MANY AREAS THE PAST FEW DAYS.
