The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Raleigh, NC wrote its last area forecast discussion before the first event at Aug 4, 3:05 PM EST, 3 hours 13 minutes earlier.
Area Forecast Discussion National Weather Service Raleigh NC 405 PM EDT Sun Aug 4 2024 .SYNOPSIS... A weak surface trough will linger over the region into Monday. Tropical Cyclone Debby is expected to slowly move into eastern Georgia and southeast South Carolina through mid week. && .NEAR TERM /THIS AFTERNOON AND TONIGHT/... As of 330 PM Sunday... Marginal risk of excessive rainfall, mainly for the Sandhills and Coastal Plain this afternoon and evening. Satellite data indicated the skies were generally partly sunny across our region. A weak short wave trough is lingering over the region this afternoon, with the higher instability and moisture over the eastern Piedmont, Sandhills, and Coastal Plain east of the trough axis. Widely scattered showers were located over the north- central and southern Piedmont. Scattered showers and some thunder were noted over the eastern Piedmont and Sandhills, with some more concentrated convection over the SE Coastal Plain. CAMS suggest the highest POP will likely remain over the eastern Piedmont, Sandhills, and Coastal Plain through the afternoon and early evening. Highs this afternoon will be a bit cooler than recent days with the additional clouds/scattered storms east. Expect mostly 80s with around 90 in the SE. Widely scattered showers/storms will diminish this evening, then expect some stratus/fog again Monday morning. Lows in the lower 70s with some upper 60s north-central. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... As of 330 PM Sunday... A Marginal risk of excessive rainfall in the SE Monday. This increases to a moderate risk of excessive rainfall in the SE Tuesday, with a slight risk elsewhere. Monday is expected to be similar to today, with some scattered convection - especially in the east and south. This will be associated with the lingering surface trough that will be over the eastern Piedmont. Therefore, the higher POP will be along and east of the trough. There is a marginal risk of excessive rainfall on a localized basis, mainly in the SE Coastal Plain Monday afternoon and evening. Stratus and fog appear likely Monday night, especially around sunrise Tuesday. Highs Monday will top out in the mid 80s to around 90. Lows Monday night will be in the 70s. The influence of Tropical Cyclone Debbie will begin to appear over portions of central NC by Tuesday and Tuesday night. The surface trough will back well inland with a broad SE flow. This will bring PW's up into the 2+ inch range for most of the region. Some convection can be expected in the SE Tuesday morning - with most of the convection expected to develop with heating Tuesday afternoon and evening. It should be more focused in the south, but spreading northwest during the late day and night. The threat of excessive rainfall is expected to increase into the moderate range SE and slight risk elsewhere. Highs will be in the lower to mid 80s with lows in the 70s. && .LONG TERM /WEDNESDAY THROUGH SUNDAY/... As of 400 PM Sunday... The main driver of weather in the extended period will be what is currently Tropical Storm Debby, which is forecast to strengthen into a Category 1 hurricane before making landfall in the Big Bend region of the FL panhandle tomorrow morning. While there is decent confidence in what it will do through Tuesday (move slowly E/NE through SE GA as it gradually weakens), its track after that is highly uncertain as there will be very weak steering flow between one mid/upper ridge extending from the Desert Southwest into the Southern Plains and another in the western Atlantic. The best guess at this time from the official NHC forecast is that the center of Debby will lift north into SC on Thursday and NC on Friday. This solution closely resembles the latest ECMWF solution and isn't too far off from the Canadian, though the Canadian is more progressive. There is also good agreement among the ECMWF ensembles that it will track through the eastern Carolinas. However, the GFS looks entirely different, as it retrogrades Debby back westward into southern GA and the central Gulf Coast from late week into the weekend. Most but not all GEFS do favor the farther north solution, and that does appear to be most likely, albeit not by a lot. The ultimate track of Debby will obviously have a major impact on how much rain we see in the extended period and how significant the flooding threat will be, but regardless it does look quite wet from Wednesday through Friday, as plenty of tropical moisture will get drawn up here even if the center of the system stays to our south. Rainfall may also be enhanced as this tropical moisture interacts with a cold front that stalls over the Mid-Atlantic. While the GFS depicts lower rainfall amounts overall, it still has above-normal PW values of around 2.25-2.5 inches for much of the time. The ECMWF meanwhile has near-record PW values of 2.5-3 inches. So carry likely to categorical POPs from Wednesday through Friday, highest in the south and east. The WPC already has a slight (level 2 of 4) risk for excessive rainfall in the south and east on Wednesday and areawide on Thursday. The best guess for rainfall amounts over the next week is from 3 to as much as 7+ inches, highest in the SE, but confidence in these details is low at this time. Heavy rain and flooding looks to be the main threat here, but gusty winds of 30+ mph can't be ruled out. Stay tuned to hurricanes.gov for the latest updates. The diurnal range in temperature will be kept down in the tropical air mass, with forecast highs only in the upper-70s to lower-80s and lows in the lower-to-mid-70s. POPs decrease to chance over the weekend and the heavy rain threat appears to lessen some, as the remnants of Debby either exit to the north or decay over the Southeast US. So forecast highs increase back close to normal, generally mid-to-upper-80s. && .AVIATION /18Z SUNDAY THROUGH THURSDAY/... As of 130 PM Sunday... 24 hour TAF period: Generally VFR conditions are expected this afternoon and evening. However, there will be scattered showers and a few thunderstorms from near KRDU east and south to KRWI and KFAY. MVFR/IFR cigs are expected again tonight, mainly from 06Z to 12Z Mon. Looking ahead: Scattered showers and storms may develop again Monday afternoon and evening with brief periods of MVFR conditions, especially around KRWI and KFAY. Otherwise, low stratus and possibly fog will be likely between 09z and 13z/Tue. Then, the weather and flight conditions through Thu will be dependent upon the track of what is currently Tropical Storm Debby as it moves slowly through the Southeast US and Carolinas. Fog/low stratus will be possible each morning, while shower/storm chances for now will be highest south and east, increasing through mid-week as the storm approaches. && .CLIMATE...
