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 Jul 8, 8:31 PM EDT, 1 hour 29 minutes earlier.
Area forecast discussion, Jul 8, 8:31 PM EDT, 1 hour 29 minutes before
Area Forecast Discussion National Weather Service Raleigh NC 831 PM EDT Sat Jul 8 2017 .SYNOPSIS... A cold front will stall over the coast later tonight and Sunday. High pressure will build aloft over the region early to mid week bringing hot temperatures. && .NEAR TERM /THROUGH TONIGHT/... As of 831 PM EDT Saturday... The main area of concern for additional severe storms is to the south and east of Raleigh through 11 PM. This region has yet to be convectively overturned and is out ahead of the large outflow moving SE currently in eastern Harnett, Johnston, and Wilson Counties. The area most favorable for warnings for damaging wind gusts will be from Fayetteville to Smithfield to Goldsboro and Wilson south and east to the Coastal Area. Weather parameters indicated residual MLCapes near 2K along with strong surface moisture convergence and Theta-E advection centered on Johnston/Wilson/Wayne supporting the above. Additional storms along the northern Piedmont are with the cold front and are not currently as strong. This area has been convectively overturned and these storms should stay sub-severe as they move ESE. The western Piedmont including the Triad is done with the severe threat. We will carry categorical to likely POP in the east, with chance or slight chance west through midnight, then taper back to chance in the east, NIL west after midnight. Lows 65-70 NW to lower 70s SE. && .SHORT TERM /Sunday and Sunday Night/... As of 245 PM EDT Saturday... The surface front will remain stalled in the far southeast on Sunday into Sunday night and will thus be the main focus for scattered diurnally driven convection in the afternoon into evening. Outside of the far southeast, expect mostly sunny skies with tolerable highs in the 85 to 90 range. Mins Sunday night will be mostly upper 60s to lower 70s. && .LONG TERM /Monday through Saturday/... As of 230 PM EDT Saturday... The frontal system will continue to linger south of the forecast area on Monday. While there is a possibility this boundary will retrograde to the north, convection should be confined to the extreme southeastern counties. By Tuesday the upper trough begins to flatten out and become very zonal. As a result the surface storm track will stay well to our north as a low pressure system moves through the Great Lakes and into New England. This pattern will keep central NC under high pressure with surface boundaries and diurnal heating being the only real forcing for convection. Temperatures will rise into the low to possibly mid 90s in most locations Tuesday Wednesday and Thursday with lows staying in the 70s. The pattern begins to change on Friday as a second low pressure system moves across the northeast but then is blocked by high pressure in the North Atlantic. This will will cause the upper level trough to deepen once again and push the surface low, and its attendant front southward. This will increase rain chances for the end of the week but should help cool off temperatures as cloud cover increases. Highs by Saturday should moderate back into the upper 80s. && .AVIATION /18Z Saturday through Wednesday/... As of 135 PM EDT Saturday... VFR conditions will predominate through the 24 hour TAF period. Diurnally driven convection will be enhanced this afternoon through evening as a cold front moves southeast across central NC. Scattered showers and thunderstorms with the potential for producing strong gusty winds are expected to blossom in the northwest (GSO/INT areas) from 20-00Z and accompany the front as it moves through. The eastern TAF sites will have a 3-4 hour window of convection as well, from ~22Z to 03Z. The threat for scattered convection will diminish after 03Z tonight as the front moves southeast of the area, where it will stall and linger near the coast through Sunday. Convection will be focused in the frontal zone Sunday, perhaps impacting the FAY and RWI sites during the afternoon/evening. A drier, more stable air mass expected to settle across central NC Monday through Wednesday, maintaining a period of VFR conditions. && .RAH WATCHES/WARNINGS/ADVISORIES... None. && SYNOPSIS...Badgett NEAR TERM...Badgett SHORT TERM...mlm LONG TERM...Ellis AVIATION...mlm
