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 8, 10:58 AM CST, 4 hours 2 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Jackson MS 1158 AM CDT Fri Jun 8 2018 .UPDATE... Updated for 18Z aviation discussion && .AVIATION... 18Z TAF discussion: Isolated showers and maybe a thunderstorm will be possible near MEI and GTR during the afternoon. Otherwise, VFR conditions will prevail through the period./26/ && .DISCUSSION... A narrow tongue of moisture along the MS/AL state line has resulted in some isolated convection this morning. HRRR 0-3km theta-e values are showing an axis of higher values in this area along with RAP and satellite derived data indicating PWs approaching 1.5 inches. The HRRR is indicating that this tongue will drift west this afternoon during max heating which should be sufficient for further convective development, albeit isolated. While microburst checklist was highlighted by decent 0-3km lapse rates and vertical totals, relative dryness of column and skinny CAPE should significantly limit any threat for wet microbursts./26/ Prior discussion below: Today and tonight: The very gradual warming trend continues today with very light flow in the atmospheric lower levels keeping moisture from doing more than gradually diffusing in from the periphery of the region. The upper level situation is not changing much, with a general ridge aloft centered out in TX and a weak upper low over FL and southern GA. The one minor difference overhead today will be a pocket of better moisture around 10 kft edging in from the east. This may (emphasize may) be enough to allow for very isolated shower and thunderstorm activity to pop up in the afternoon to early evening hours along and east of the I-55 corridor. Some convective allowing models were surprisingly aggressive with this thinking, but given precipitable water values will largely remain 1.5 inches or less I'm still not on board with more than isolated activity (10-15 pops max). Regardless, will reflect some small potential in areas mentioned in the official forecast. Otherwise, expect a bit more in the way of puffy clouds around today, although still plenty enough sunshine to get high temperatures up to, or slightly hotter, than was the case yesterday. Fortunately, peak heat index values should still remain shy of 100 degrees in all areas. Tonight, expect slightly muggier conditions with a little more cloud cover continuing the subtle warming trend. Lows should range from 68 to 72 degrees with perhaps a few patches of late night fog, especially in any areas where some showers can manage to hit the ground. /BB/ Saturday through next week: Some isolated shower/storm activity may develop Saturday morning as a weak disturbance rotates around the upper high centered over the Plains and merges with a weak disturbance that will be placed along the Gulf Coast. However, most of the ArkLaMiss will remain dry on Saturday as temperatures reach the low to mid 90's. Increasing low and mid level southerly flow through the weekend and early next week will result in increased humidity values across the region. Heat index values will peak in the upper 90s to near 100 Saturday through Tuesday. Rain/Storm chances will increase on Sunday as upper level heights begin to fall over the eastern CONUS and another upper shortwave sweeps through just to the north of the ArkLaMiss. Chances of rain and storms will subsequently increase each day as we get into early next week(Monday-Wednesday) as the upper ridge loses its influence over our region. These storms will be more diurnally driven and widespread. Temperatures are expected to remain above average through the period but showers and storms will help limit temps at some sites. Model solutions begin to diverge as we get closer to the end of next week with the euro suggesting a drier more mundane solution than the wetter and more active GFS. && .PRELIMINARY POINT TEMPS/POPS...
