Area Forecast Discussion National Weather Service Jackson MS 632 AM CDT Sun Jul 21 2019 .UPDATE... Updated for 12Z aviation discussion && .AVIATION... 12Z TAF discussion: The patchy fog in south Mississippi and the low stratus deck in east Mississippi this morning will both mix out in about an hour or two. There are already scattered showers and storms developing in central Mississippi which are expected to increase in coverage through the morning and bring additional potential for reductions in ceiling and visibility at all area TAF sites into the afternoon hours. This activity will dissipate in the evening and VFR conditions will then prevail. /10/ && .DISCUSSION... Today and tonight: Today will be much like yesterday with a mid- level weakness in the ridge still located over our area. This disturbance is likely to trigger convection early in the day again and to spread throughout the entire CWA. With very little steering mechanisms in place, storm movement will be slow. This in conjunction with the high moisture content in the air (PWs above 2 inches) may lead to some localized flash flooding issues. The confidence in the flash flooding threat is low though since it will likely be a very localized issue and not widespread. In most areas, our summer soils can soak up more than 2 inches of rain per hour before becoming bogged down and over saturated. Due to the increased coverage of afternoon storms today, high temperatures will top out in the upper 80s/near 90 across the area. The storms will begin to dissipate with sunset this evening and will clear for an overall quiet night with lows falling into the low to mid 70s. /10/ Monday through Saturday: Mid level wave, diving through the upper MS valley at the beginning of the period, will push a cold front into northern MS Monday morning. As the boundary encounters a warming/destabilizing airmass ahead, widespread convection will develop over northern portions diminishing over central sections during the evening. The boundary will continue southward into southern sections Tuesday where a good coverage of convection will once again develop. To the north, drier air will begin spilling into the area as dewpoints fall into the lower 60s. The convection will diminish over the south during the evening with cool/dry advection continuing overnight into Wednesday. High pressure will shift east into the OH valley Wednesday night allowing advection to diminish and setting up the best night for radiational cooling. Thursday and to a large extent Friday will remain convection free as the Gulf of Mexico remains cutoff in light easterly flow. Some isolated storms may be possible late in the day Friday over the far southeast where the old boundary begins coming back north. Most of this looks to hold off until Saturday. /GG/ && .PRELIMINARY POINT TEMPS/POPS...
