Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Jackson, MS (KJAN), launched 12:00Z, 2.9 hours before the alert went out and 159 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

- Isolated severe storms are possible over the area today and again on Friday.

Area Forecast Discussion...UPDATED National Weather Service Jackson MS 713 AM CDT Thu Jun 18 2026 ...New AVIATION... .KEY MESSAGES... - Significant flash flooding threat continues with conditions worsening this morning into the afternoon. - Rainfall will continue on Friday. Flooding impacts may linger. Rainfall does not end quickly, but rather gradually tapers over the course of several days. - Isolated severe storms are possible over the area today and again on Friday. && .DISCUSSION... Issued at 1211 AM CDT Thu Jun 18 2026 Today... The remnant tropical low feature is expected to bring a significant flash flood threat to southeastern portions of the area today as soil moisture remains high and antecedent rainfall has made this area vulnerable. As much as 4-7 inches of rain could fall, locally higher upwards of 10-12 inches in some guidance amid the tropical airmass, support of efficient rainfall rates. 00z regional soundings show a 2.1 to 2.2 inch PWAT airmass, which is similar to Tuesday. Considering this, we know that 8 inch amounts were observed or estimated, so it is likely this airmass would still be capable of those amounts. Further, probabilities for 8 inches have increased to 20% in spots on CAM guidance. Additionally, there will be a marginal severe threat with this system, primarily for damaging wind gusts and brief, weak tornadoes. Tropical remnants can enhance low level shear, and back surface winds. Considering this along with a very moist BL, brief tornadoes are possible, particularly this morning associated with core convection. Rainfall does continue even after the remnant low passes with a trailing boundary. Placement of this potential is still uncertain, however a lot CAM guidance has shifted this south, perhaps even south of our area (Wilkinson, Amite, Pike, Walthall). But, should this materialize, it would exacerbate flood risk and any ongoing flooding as any additional rainfall would push things over the edge. Furthermore, this would be a training convection scenario that could add to totals. It is possible that convection reinvigorates along this boundary Friday, but again, it is uncertain. Through mid next week... The boundary begins to make headway into the area by the weekend and likely washes out this weekend. Airmass modification is likely slim, but PWAT, while still supportive of additional rainfall, will be more seasonal (1.5-1.7). This should provide some "break" from the onslaught of moisture, with coverage overall more scattered this weekend. Additional rainfall amounts this weekend generally look to be in the 1 to 2 inch range. Southwesterly flow will continue to reinforce rain chances through the remainder of the period, but increased westerly/northwesterly flow by the middle next week may mean that relief from heavy rainfall may be on the way. Towards the end of the period, there is potential to transition towards a NW flow regime as a ridge strengthens over the SW CONUS. Right now in the guidance it looks like there is potential for a stalled boundary to be in place, while multiple shortwaves ride the ridge. All the while, low level flow will likely remain southwesterly as we remain under the western flank of the low level ridge. This could set up the area for rounds of severe weather, likely MCS scenario. Of course, more details will be provided as they become available. /SAS/ && .AVIATION... (12Z TAFS) Issued at 713 AM CDT Thu Jun 18 2026 Lowering ceilings and increasing chances for RA will continue as the remnants of Tropical Storm Arthur move across the forecast area. Areas of rain will be accompanied by reduced visibility and potentially gusty winds. Some improvements in ceilings and/or visibility is likely after 18/22-23Z, with decreased rain coverage into the evening hours. Additional lowered ceilings and/or visibility will develop again overnight, with increased rain chances as well through the end of the TAF period. /NF/DC/ && .PRELIMINARY POINT TEMPS/POPS...
