Area forecast discussion, Apr 25, 1:12 AM CDT, 2 hours 35 minutes before
Area Forecast Discussion National Weather Service Jackson MS 112 AM CDT Thu Apr 25 2019 .UPDATE... Updated for 06Z aviation discussion && .AVIATION... 06Z TAF discussion: VFR conditions continue across the area with the exception of the Pine Belt, which is experiencing IFR to LIFR ceilings this morning. Expect flight categories to continue to diminish as a line of showers and storms moves into the area from the west. Much of the day should see sub-VFR ceilings along with rain and thunderstorms. Some storms could be severe. Conditions will improve this evening, with VFR ceilings likely to resume. /28/ && .DISCUSSION... The 00Z Thu JAN sounding showed a cap at 800mb and local radars were virtually free of returns over our CWA but regional radars had convection developing over east Texas that models still depict will move into the southwest most portions of our CWA just after 4 am. Water vapor imagery showed the circulation around a closed low spinning over north central Texas. Surface analysis had a rather ill-defined 1006mb low over south Texas. These features will continue to approach our CWA tonight and move across our CWA. This will increase our rain chances toward morning. Forecast remains on track. /22/ Prior discussion below: Tonight through Tomorrow night... Warm weather will continue into the evening but there are increasing PoPs over night. A low pressure system currently over Texas will approach our area with an ongoing line of storms moving in from the west after midnight. Some of these storms could produce strong winds and locally heavy rain but our primary severe weather threat will be with a second round of storms which will develop by mid morning. High-Res guidance shows some slight differences with regard to timing but the atmosphere should support the potential for severe thunderstorms as this second round becomes organized. Forecast MLCAPE values up to 1500 J/kg, 0-6 km shear of 40-50 kts, and helicity values of 250-300 are less than recent events, but are adequate for damaging wind gusts and a tornado or two especially with any bowing line segments. The greatest threat will be in the slight risk area which is roughly our MS counties south of I-20. Thunderstorms should exit east of our CWA by 5-7 PM. A few showers or an isolated storm could linger into the evening. Friday through Wednesday... In the wake of the system, an upper level ridge and surface high pressure will help keep temperatures near or above normal headed into the weekend. A slight chance of showers will accompany a decaying front as it dips into the northern part of our area on Saturday night into sunday morning. For the rest of the work week, more upper level ridging will occur bringing warmer temperatures and mostly dry weather. On the western side of the ridge there is a chance of some return showers for Wednesday mainly across northeast LA and southeast AK./JNE/NF/JPM && .PRELIMINARY POINT TEMPS/POPS...
