NWS Jackson, MS wrote its last area forecast discussion before the first event at Jun 5, 11:49 AM CST, 2 hours 50 minutes earlier.
Area Forecast Discussion National Weather Service Jackson MS 1249 PM CDT Fri Jun 5 2020 .UPDATE... Updated for 18Z aviation discussion && .AVIATION... 18Z TAF discussion: Mainly VFR conditions will prevail through the TAF period at all terminals. A cumulus field has developed across the region, but ceilings will remain VFR. The main concern will be thunderstorms this afternoon into the evening hours. At least VCTS will be possible at all locations during the mid to late afternoon. In addition, a line of storms is expected to move south from the Memphis area into north and central Mississippi. These storms will be more organized and will pose a threat for severe wind gusts of 50-60kts. This line is currently expected to stay mainly along and east of I-55 with the greatest impacts at GLH/GWO. Will amend TAFs as necessary once convective trends become more apparent. Brief reductions in both visibility and ceiling can be expected with any storms through the evening hours. Winds will be light to calm overnight. /TW/ && .DISCUSSION... Morning water vapor imagery and analysis continues to depict upper ridging in place across northern Mexico and into west Texas and New Mexico. Broad diffluent northwesterly flow is in place across the Lower Mississippi River Valley downstream of the upper ridge. An overnight MCS continues to propagate southeast across far southeastern Missouri with an associated MCV noted as well. Heading through the rest of the morning and into the afternoon, mostly sunny skies will give way to partly cloudy skies with typical development of an afternoon cumulus field is expected. Temperatures are already warming quicker than forecast, so boosted afternoon highs another degree or so across the area with temperatures climbing into the low to mid 90s. Heat index readings in the 100-105 degree range will be possible for a few hours this afternoon, especially over northern portions of the ArkLaMiss Delta region. The primary focus for the near term period will be on severe thunderstorm potential this afternoon and into the evening hours. While the overall signal is similar, 12z hi-res CAM guidance continues to struggle with timing and coverage of storms, especially with respect to the development of an MCS later this afternoon into the evening. The overall forecast thinking is for isolated to scattered diurnally driven storms to develop across the area this afternoon. Local microburst checklist using a modified 12z JAN sounding supports locally damaging winds with this activity owing to strong instability with 3500 J/kg of SBCAPE and upwards of 1300 J/kg of DCAPE. Later this afternoon and into the evening an MCS is expected to develop over far western Tennessee and move south into northern and central Mississippi mainly along and west of I-55. Damaging winds up to 70mph will be possible with this line of storms. Both the slight and marginal risk areas have been expanded in the HWO/graphics to account for both the afternoon and evening storms. A few showers may linger through the overnight hours, but the majority of storms should be dissipating shortly after midnight. /TW/ Prior discussion below: Today and Tonight...Another hot humid day is expected across the ArkLaMiss as we end the work week. Highs this afternoon will climb into the lower 90s across much of the region. This, combined with dew points in the 70s, will result in heat index readings climbing to around the century mark this afternoon. So please take the proper precautions against heat stress, if engaged in outdoor activities during the afternoon hours today. Lows tonight will range from the upper 60s to middle 70s. Diurnally driven scattered showers and storms are also expected to breakout across the forecast area this afternoon. Several high-res models also indicate the potential for a complex of thunderstorms driving south, under northerly flow aloft, across the western half of the CWA late this afternoon and evening. In the Delta region where instability will be rather robust, potentially around 4000 J/kg of MU Cape , a "Slight Risk" for severe storms will exist for today. A "Marginal Risk" for isolated severe storms will exist for portions of Central, West, and Southwest Mississippi, into East Central Louisiana. Damaging wind gusts of 70 mph will be the primary concern with storms in the "Slight Risk" area, but quarter size hail will also be possible. In the "Marginal Risk" area, damaging wind gusts of 60 mph will be the main concern, with hail up to the size of quarters also possible. Nearly continuous lighting strikes can also expected with this potential MCS, along with heavy downpours with any of today's convection. This could result in the ponding on water on roads, as well as in low-lying and poor drainage areas. /19/ Saturday through Next Thursday...The main focus through this forecast period will be Tropical Depression Cristobal. Cristobal is currently over inland parts of the Yucatan Peninsula and is forecasted to re-emerge over Southern portions of the Gulf of Mexico Friday and from there continue to move north. By the weekend, Cristobal will continue to push northward making its transition to the States nearing the LA/MS coast line sometime Sunday. A mid-level ridge will help suppress and slowdown the progression of Cristobal and different model guidance(GFS and ECMWF) supports this, however these models have a slight difference in the evolution of the ridge and how long it will take for it to slide east will also help determine the progression of Cristobal. I must point out, that there is still a vast amount of uncertainty as it pertains to Cristobal's track, intensity, and impacts, but for now there is building confidence that heavy rainfall might be a concern for some portion of the ArkLaMiss. Most of the beginning half of Saturday will be dry but as we get into afternoon and evening hours, rain chances will start to increase. Our greatest chances for rain will be Sunday afternoon through Wednesday. As mentioned before, confidence in heavy rainfall affecting our region in a short period of time is increasing but with Cristobal's track still questionable, advertising heavy rainfall or any other impacts/threats like severe, won't go into the HWO at this time. Will continue to hold off and assess new data day by day. Post TD Cristobal, models hint at a cold front dropping from the north. A dry airmass will filter into the region and we can expect to see some rain free weather for a couple of days at the end of next week. Temperatures will be warm this weekend with highs in the low-mid 90s and even for the next working week temperatures will be in the upper 80s to near 90 degrees. We will continue to monitor Cristobal, analyze new guidance, and as always give updates but most importantly stressing the fact to make sure you have a plan in place! /JNE/ && .PRELIMINARY POINT TEMPS/POPS...
