Area forecast discussion, Aug 9, 2:40 PM EDT, 42 minutes before
Area Forecast Discussion National Weather Service Raleigh NC 240 PM EDT TUE AUG 9 2016 .SYNOPSIS...Slightly drier and hotter conditions will develop late this week into this weekend as an upper level ridge strengthens along the Carolina coast. && .NEAR TERM /THIS AFTERNOON AND TONIGHT/... As of 1230 pm Tuesday... An upper level low offshore the Southeast coast will move slowly west toward the FL Peninsula today, while a broad surface low persists over the Deep South. Southeasterly /onshore/ flow (sfc-H85) will broaden/expand inland toward the Appalachians today, pushing what (if anything) remains of the stalled frontal zone to the N/W this afternoon and enhancing orographic ascent on the eastern slopes of the southern Appalachians. Whether convection develops in onshore flow over the SE Coastal Plain/Sandhills or in the NW Piedmont along a differential heating boundary between 15-18Z, convective coverage is expected to shift west of the Highway 1 corridor as the afternoon progresses, with the greatest coverage expected in the W/NW Piedmont between 21-04Z. Chances for convection should diminish after midnight, though isolated showers in onshore flow will remain possible through much of the overnight period. Expect highs ranging from the the lower 80s in the far NW Piedmont to near 90F n the Sandhills and SE Coastal Plain. Lows Tuesday night should be similar to previous nights, in the low/mid 70s. -Vincent && .SHORT TERM /WEDNESDAY AND WEDNESDAY NIGHT/... As of 1230 pm Tuesday... Expect a similar pattern to today, albeit with a decreased overall potential for diurnal convection, particularly over eastern NC where synoptic subsidence attendant a strengthening ridge aloft may suppress convective development altogether. Expect the best chances (30-40%) along/west of the Highway 1 corridor between 21-04Z. Expect highs ranging from the mid 80s (NW) to lower 90s east. Lows Wednesday night in the lower to mid 70s. -Vincent && .LONG TERM /THURSDAY THROUGH TUESDAY/... As of 240 PM Tuesday... The upper level ridge is forecast to continue to build westward from the western Atlantic into the southeastern and southern mid-Atlantic states mid to late week. This will increase the mid/upper level subsidence especially as the upper ridge peaks in strength Thursday into Friday night. The surface ridge will be located near Bermuda, which is a climatological preferred location for mid-summer. The low and mid level flow around the high will continue to pump plenty of moisture in from the south. Dew points will remain high (in the lower to mid 70s). There will be less in the way of convection with more subsidence and less surface moisture convergence. However, isolated to widely scattered thunderstorms will still occur in the afternoon and early evening Thursday and Friday. It will be hotter than recent days with highs in the lower to mid 90s. Lows will be in the lower to mid 70s through Saturday. Heights are forecast to back off this weekend from the west allowing deep moisture to return to at least the western third of our region, (western Piedmont), over the weekend. The increased cloud cover and chance of mainly PM showers/thunderstorms will allow highs to back off into the upper 80s NW. Highs will still be in the lower 90s elsewhere through the weekend. The chance of widespread showers and thunderstorms will increase early next week as the flow aloft transitions to a more SW flow. A cold front will slowly sag southward toward the southern mid- Atlantic providing a focus for convection. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... As of 1230 pm Tuesday... Difficult forecast. MVFR to LIFR ceilings affected the INT/GSO/RWI terminals as of 15Z this morning, but should gradually lift and improve to MVFR/VFR by early/mid afternoon. VFR conditions were already present at FAY/RDU at 15Z, though broken MVFR ceilings will be possible early/mid afternoon, and scattered to numerous convection will be possible at all terminals, particularly at INT/GSO, with the greatest coverage between 21Z this afternoon and 04Z tonight. Chances for convection will gradually diminish after 04Z (midnight), however, sub-VFR ceilings and/or visbys in fog are likely to develop once again during the pre-dawn hours at most if not all terminals, primarily between 09-15Z Wednesday. Looking Ahead: Expect a gradual decrease in convective coverage/ chances late week into this weekend as an upper level ridge strengthens along the Carolina coast. -Vincent && .RAH WATCHES/WARNINGS/ADVISORIES... None. && SYNOPSIS...Badgett/V NEAR TERM...V SHORT TERM...V LONG TERM...Badgett AVIATION...V
