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 Jun 5, 5:48 PM CST, 16 minutes earlier.
Area Forecast Discussion National Weather Service Jackson MS 648 PM CDT Fri Jun 5 2020 .UPDATE... Updated for 00Z aviation discussion && .AVIATION... 00Z TAF discussion: Line of thunderstorms are moving through the I-20 corridor. Behind this, light to moderate rain is occurring. This is affecting TAF sites along and north of I-20 and leading to reduced vis in the strongest storms. Elsewhere VFR conditions continue. This line will continue south this evening. Light rain will linger behind this activity through the evening but VFR conditions and quiet weather expected overnight into tomorrow. /28/ && .DISCUSSION... Through tomorrow: As of this afternoon, a severe MCS is pushing south along I-55 in northern Mississippi. This line of severe storms will continue to move south through northern and into central Mississippi. 18z JAN sounding sampled 4600 J/kg of SBCAPE and 1100 J/kg of downdraft CAPE, which will be supportive of damaging wind gusts of 60-70mph. The ongoing slight risk in the HWO/graphics remains well placed and no changes were needed. The MCS will weaken this evening as it pushes south of I-20 with only a few showers and perhaps an isolated storm lingering through the overnight hours. By tomorrow, Tropical Storm Cristobal will continue to move north across the Gulf of Mexico as upper ridging shifts east into the Middle Mississippi River Valley. Associated cloud cover will begin to increase across southeast Mississippi, but the majority of any rainfall will remain offshore and south of the ArkLaMiss region through the day tomorrow. A few isolated to scattered diurnally driven showers and storms will be possible, but coverage is expected to be lower compared to today. /TW/ Saturday night through next week: The primary focus will be on the impacts of Tropical Storm Cristobal as we finish up the weekend and go through early next week. Per latest information from NHC, we expect "Cristobal" to officially make landfall late Sunday over the eastern LA coast. Thereafter, the center of the decaying system will track NNW through western portions of the forecast area, with impactful wind/rainfall will spread across most of the forecast area as we go from Sunday night through Tuesday. The rainfall associated with this system has the chance to the most significant impact for the ArkLaMiss region. Initially, the bulk of rainfall is occurring on the north/east side of the track as it moves through a weakness in the subtropical ridge over the Gulf of Mexico, but as "Cristobal" approaches the LA coast and then moves inland, it will begin to make a westward turn in response to a ridge building to the north. Given greater ridge influence, ascent and the heaviest rainfall should focus closer to the center and the bulk of guidance shows the heaviest QPF shifting to west of the I-55 corridor with time. An HWO graphic shows the increasing rainfall/flooding threat, but it is also worth noting that there has been a noticeable eastward shift in the guidance and this may need to eventually be reflected in the graphic. Otherwise, there will likely be a threat for brief tornadoes and strong wind gusts, perhaps near TS strength Monday. "Cristobal" is expected to get swept up in the westerlies mid week with a strong upper level trough pushing a cold front through the forecast area. While convective rainfall will accompany the front, expect drier conditions to finish up the week behind it. /EC/ && .PRELIMINARY POINT TEMPS/POPS...
