The remnants of Hurricane Harvey moved across the ArkLaMiss region on August 30th and 31st and brought gusty winds and rain to the region. As Harvey decreased to a depression on the 31st, gusty winds still remained across portions of the region into the early parts of September.

The episode as NWS JAN wrote it up.
The remnants of Hurricane Harvey moved across the ArkLaMiss region on August 30th and 31st and brought gusty winds and rain to the region. As Harvey decreased to a depression on the 31st, gusty winds still remained across portions of the region into the early parts of September. This resulted in some downed trees outside of any shower activity.
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 Jackson, MS wrote its last area forecast discussion before the first event at Aug 31, 11:34 PM CST, 1 hour 26 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Jackson MS 1234 AM CDT Fri Sep 1 2017 .UPDATE... Updated for 06Z aviation discussion && .AVIATION... 06Z TAF discussion: The center of the remnants of Harvey is slowly starting to pull north and northeast away from northern portions of the forecast area, although a few showers and gusty west winds (up to 35 mph) continue from GWO east through GTR/CBM into the overnight hours. Here and further south some patchy MVFR conditions due to ceilings will be found through the night with most areas likely turning VFR after daybreak tomorrow. There is some chance for MVFR ceilings to build back in temporarily from the midday through afternoon at most sites except for HBG/PIB. West to northwest surface winds will be a little gusty at times during the bulk of the day tomorrow (especially at GTR/CBM), but peak speeds in all areas should remain less than 30 mph and be noticeable less gusty than was the case during the day Thursday. /BB/ && .DISCUSSION... As of 2z, the remnants of Harvey were centered over northern Mississippi with the majority of the CWA now under northerly to easterly flow. The flow on the back side is advecting in drier and lower ThetaE air which has helped to greatly reduce precip coverage over the area. As of this writing, a few showers were located along the Hwy 82 corridor closer to the center of circulation and another band of showers was located along the I-20 corridor where a tongue of relatively higher moisture has hung on a little longer. For the rest of tonight, expect precip in the form of showers to become limited to the north and east portions of the area before decreasing by the morning hours. The only remaining hazard will be gusty winds up to 35mph for the northeastern corner of the CWA through the evening. These winds will gradually relax through the night by Friday morning as the tighter pressure gradient pulls away from the area. Adjusted the HWO/graphics accordingly. No other changes were needed to the ongoing forecast. /TW/ Prior discussion below: Today through Friday: The center of Tropical Depression Harvey is now near Cleveland, MS now. This system continues to bring light showers to our area as well as a few rotating showers in our northeastern counties. Since Harvey has shifted NEward this afternoon, so has the associated tornado threat. The remaining threats for this system include winds and flooding. Winds around the area this afternoon have maintained sustained speeds of 15 to 20 mph with gusts as high as 33 mph at KGTR and KCBM. This threat will begin waning after 00Z when heights begin to rise again. As for flash flooding, the threat is relatively low as rainfall rates are below 1"/hour, a rate at which our soils can easily maintain, especially still being in the green season. The flash flood watch will therefore be allowed to expire at 7pm tonight if not canceled before then. Going into tonight, Harvey will exit the area around 03Z. Light rain on the back side of Harvey will continue to affect the northern parts of the CWA through the night and through tomorrow morning. Overall, once the residual rain exits the area, Friday should be a quiet day with conditions returning to normal. High temperatures will remain cool in the mid to upper 80s. /10/ Friday night through Sunday night: Notably drier air will move into our area just in time for the weekend. This can be seen clearly in model 700 mb RH fields (20-30C Td depressions) and progged PW (dropping to around an inch). Meanwhile at the surface, dewpoints will remain down in the 60s to near 70 throughout the weekend. No rain is in the forecast for the weekend. Next week: Southerly low level flow will return by Monday, with moisture returning through the day as well. This will bring a chance for storms back into the southern portion of the area by the afternoon/evening. An upper trough will deepen over the eastern portion of the CONUS, bringing higher rain/storm chances across the entire area as a solid cold front moves through Tuesday into Wednesday. Behind the front, another intrusion of drier air is anticipated with dewpoints dipping into the 50s and temps possibly following suit Wednesday night. This will be a little taste of fall as we head into football season. /DL/ && .PRELIMINARY POINT TEMPS/POPS...
