NWS Raleigh, NC wrote its last area forecast discussion before the first event at Aug 10, 8:20 AM EST, 1 hour 13 minutes earlier.
Area Forecast Discussion National Weather Service Raleigh NC 920 AM EDT Thu Aug 10 2023 .SYNOPSIS... An upper level trough will move east across the region today. This will be followed by weak high pressure on Friday. A hotter air mass will move into the region over the weekend into Monday. && .NEAR TERM /TODAY AND TONIGHT/... As of 920 AM Thursday... With the 9am update, the Storm Prediction Center has trimmed the Slight Risk (level 2 of 5) for severe weather. Instead of nearly the entire forecast area being in the level 2 risk, the western extent now follows a line close to Oxford, Siler City, Camp Mackall, and Harrells. Areas west of that area are now under a Marginal Risk (level 1 of 5), while areas to the east remain under a Slight Risk (level 2). The leftover area of thunderstorms from yesterday's convection is currently entering the Triad, and it appears that rain will be widespread but it appears that this region of thunderstorms will have a limited potential to be severe across western counties. While this area could intensify as it moves east, this scenario does not appear likely considering extensive cloud cover over the entire region. A more likely scenario now appears to be that after rain moves through this morning, a period of clearing could allow for destabilization of the atmosphere early this afternoon and a second line of showers/thunderstorms in the mid/late afternoon would be the better chance for severe weather. Expect the morning convection to hold temps down a bit in the west, with recovery this afternoon into the lower to mid 80s. The east will likely have convection develop or move in as highs reach the mid to upper 80s. Showers and storms will quickly move east of the region with only isolated evening storms. Lows tonight will be in the upper 60s to lower 70s. && .SHORT TERM /FRIDAY AND FRIDAY NIGHT/... As of 315 AM Thursday... There will be another (last in this series) upper level disturbances that is expected to track east across central NC during Friday. There will be another chance of showers/thunderstorms, especially in the afternoon and early evening Friday. With less wind to work with aloft, organization of storms is not expected. Highs will be mostly in the mid 80s NW to lower 90s Sandhills. Lows will be in the mid 60s to lower 70s. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... As of 330 AM Thursday... A low-amplitude trough through the depth of the troposphere will be in the process of moving off the Carolina coast Saturday morning. In its wake, mid/upper level subsidence of 20-30dam of H5 height rises and deep layer drying (PWAT falling to 1.5 inches) will certainly limit cloud cover and the potential for storms. Some isolated showers may still be possible along the Piedmont trough firmly in place along the US-1 corridor (depicted well in the 00z Canadian with pockets of QPF along the lee-trough) with 1500-2500 SBCAPE. The abundant amount of dry air in the mid to upper level will certainly not allow this amount of instability to be realized due to dry-air entrainment and may even keep any activity showery in nature with lack of deeper convection to support thunder. High clouds will begin to spread in from the west as cloud debris from convection upstream filters into the area. Overall, Saturday should be mostly sunny and allow for the first of two days with temperatures 5-10 degree above normal, driven by the easterly advection 20-21C 850mb temps and a slight eastward wobble of the sub-tropical ridge to the mid/lower MS Valley. Heat index values are a little uncertain as forecast soundings show a fairly deeply mixed boundary layer with plenty of dry air to mix down to the the surface (00z deterministic guidance suggesting dew points mixing out into the 60s for a majority of the area and low 70s in the far southeast), which would lower heat index values. Sunday is even trickier. Although another 12-24hrs of 850mb easterly WAA raises temps to 21-22C would likely lead to a higher ceiling in regards to the maximum temperature, moisture advection accompanies the warm air and increases PWAT to near 2 inches. At the surface, a lee-trough and sea-breeze will provide a focus for showers/storms with the addition of CIN being eroded by 18z as convective temperatures are reached. Increasing cloud cover from convection and cool outflows may halt temps from rising to their full thermodynamic potential leading to low confidence in heat index values for Sunday. A vigorous shortwave is forecast to move into the Great Lakes region early next week and migrate through the Northeast Tues. Timing, and strength of the shortwave are still uncertain, however, ensemble solutions are picking up on this feature with their each known biases on timing (GEFS - fastest, CMCE - slowest, and the EPS - in the middle). Deterministic guidance then shows a deep occluded low over the Great Lakes with a trailing cold front moving through the OH Valley Mon and through the southern Mid-Atlantic Tues/Tues night. Ahead of the front a severe threat may be possible Mon afternoon/evening, but too many uncertainties exist to say anything for certain at this point. && .AVIATION /12Z THURSDAY THROUGH MONDAY/... As of 700 AM Thursday... 24-hour TAF period: A line of showers and thunderstorms with MVFR ceilings is expected to move in from the west, affecting INT/GSO early to mid morning (roughly 12-15z) and the eastern terminals late morning to early afternoon (roughly 14-17z). Some of the storms could be severe, and they could be accompanied by a period of gusty winds and IFR ceilings/visibilities, so added a TEMPO group everywhere to show this potential. Skies are expected to clear somewhat with mainly VFR conditions returning in the afternoon. Additional scattered showers and storms will be possible in the afternoon and early evening. Outlook: Isolated to widely scattered showers and storms are expected through Sunday, although coverage should be minimal on Saturday. More widespread convection is possible on Monday as a cold front approaches. && .RAH WATCHES/WARNINGS/ADVISORIES... None. && SYNOPSIS...Badgett/GIH NEAR TERM...Green/Badgett SHORT TERM...Badgett LONG TERM...Swiggett AVIATION...Badgett/Danco
