The local office's own words before this special weather statement went out, 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 this special weather statement went out at Aug 3, 7:50 PM EDT, 4 hours 39 minutes earlier.
Area forecast discussion, Aug 3, 7:50 PM EDT, 4 hours 39 minutes before
AREA FORECAST DISCUSSION National Weather Service Raleigh NC 750 PM EDT Mon Aug 3 2020 .SYNOPSIS... Tropical cyclone Isaias will track north along the Georgia coast late this afternoon and the South Carolina coast this evening. The storm is expected to make landfall across the far northern South Carolina coast before midnight and then move north-northeast across eastern portions of North Carolina tonight through Tuesday morning. A more typical summertime pattern of afternoon and evening thunderstorms will then return for the remainder of the week. && .NEAR TERM /THROUGH TUESDAY/... As of 335 PM Monday... The official forecast for Tropical Storm Isaias shows the storm moving a touch faster through North Carolina, and it now appears that the bulk of the impacts from the storm will be felt during the overnight hours as opposed to persisting into Tuesday morning. 25+ mph winds should first be felt right around sunset in southern Sampson County, with winds ramping up during the rest of the evening and into the overnight hours. The eye of the storm is expected to pass to the east of the forecast area, so winds should remain elevated with the storm moving through. Although Isaiah is still forecast to briefly become a hurricane before making landfall, no hurricane force winds are expected in the forecast area. With the quicker storm movement, all wind speeds greater than 25 mph should be out of the region by 8am Tuesday. The slightly faster storm speed should also result in slightly lower rainfall forecasts as the storm will be over the region for less time. Still think that there will be 4-6 inch rainfall totals along the I-95 corridor, but that the overall coverage of those highest rainfall totals will be reduced. With all widespread rainfall out of the forecast area by Tuesday afternoon, think that a chance for scattered showers/thunderstorms will remain across the forecast area with clearing skies behind the storm, except sinking motion in the wake of the storm will likely limit overall coverage. With the storm moving out of the region more quickly, bumped up high temperatures another degree or two, into the mid to upper 80s. && .SHORT TERM /TUESDAY NIGHT THROUGH FRIDAY NIGHT/... As of 340 PM Monday... A slow moving cold front will move across the western NC mountains on Tuesday evening and then stall across central NC for much of the short term period into Friday night. A broad upper trough axis stretching from the Great Lakes into the northern Gulf of Mexico early in the period gradually weakens through the work week although the trough axis lingers to our west. The result will be a period of unsettled weather with mainly afternoon and evening showers and storms. Given the significant rain that will fall across parts of the Carolinas tonight and early Tuesday, any significant rain from thunderstorms on Wednesday could result in some additional or enhanced flooding issues. Temperatures on Wednesday in the wake of the departing TC will range near seasonable around 90 and then cool a slight bit into the mid to upper 80s on Thursday and Friday. Morning lows will range around 70. -Blaes && .LONG TERM /SATURDAY THROUGH MONDAY/... As of 305 PM Monday... The cold front that stalls out over NC in the wake of TS Isaias looks like it will washout or be fairly unidentifiable by Saturday. With one shortwave moving off the Mid-Atlantic coast on Saturday and the central US ridge trying to build eastward, a general WNW flow aloft should become established into early next week. This pattern suggests near normal temps each day, with diurnal convection potentially augmented/enhanced by disturbances in the NW flow aloft. Confidence in the timing of those disturbances would be fairly low, so will keep pops near climo in the lower end chance range. Afternoon highs 88-92. && .AVIATION /00Z TUESDAY THROUGH FRIDAY/... As of 745 PM Monday... Aviation conditions will deteriorate from the south this evening as widespread showers, thunderstorms, and strengthening winds associated with the core of the tropical storm spread north across the Sandhills, the Coastal Plain and in the eastern Piedmont. This will result in widespread IFR to MVFR conditions in heavy tropical downpours at KRDU, KRWI and KFAY, especially between 03Z and 09Z. The strongest winds with gusts to around 45kts at KRWI, 35kts at KFAY and 25kts at KRDU will occur for a 3 to 5 hour period during this window. Further west, periods of showers and storms, heavy at times with less extreme winds are expected at the KGSO and KINT terminals. As the storm rapidly moves northeast and exits NC into VA by 12Z, conditions will improve quickly from south to north just after daybreak Tuesday with VFR conditions and winds gusts falling below 20kts by 16Z Tuesday. A large area of BKN cumulus will develop with bases around 4kft during the afternoon with the potential for scattered afternoon and evening thunderstorms. Looking further ahead, a more typical summer time pattern with mainly afternoon and evening showers and storms are expected through Friday. -Blaes && .RAH WATCHES/WARNINGS/ADVISORIES...

WILL AFFECT NORTHEASTERN SCOTLAND...WAYNE...SAMPSON...
HARNETT...CUMBERLAND... WAKE...SOUTHWESTERN WILSON...JOHNSTON...HOKE
AND SOUTHWESTERN FRANKLIN COUNTIES UNTIL MIDNIGHT EDT...
At 1104 PM EDT, Doppler radar was tracking an area of showers and
isolated thunderstorms along a line extending from near

Heavy rain of one half to three quarters of an inch per hour will
accompany these showers and isolated storms; and minor flooding will
be possible.
Locations impacted include...
Raleigh, Fayetteville, Cary, Goldsboro, Smithfield, Clinton, Raeford,
Lillington, Fort Bragg and Wake Forest.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Locally heavy rain will quickly reduce visibility and result in
ponding of water on roadways, standing water in low lying areas, and
minor flooding of creeks, streams, and areas of poor drainage.
Drivers are urged to slow down and use extra caution to avoid
hydroplaning, especially in urban areas where prolonged heavy rain
can quickly lead to flooding.
