Area Forecast Discussion National Weather Service Jackson MS 434 AM CDT Sat Jul 20 2024 ...New DISCUSSION... .DISCUSSION... Issued at 434 AM CDT Sat Jul 20 2024 Today through Tonight... Early morning water vapor/RAP analysis indicate perturbed flow/trough axis centered over the MS Valley to Gulf Coast, with Rex Block synoptic pattern locked in for the considerable future. The main corridor of the vertically stacked low is analyzed over the Hudson Bay. Deep ridging persists in the Desert Southwest, Rockies to the Interior Plains/Prairie Provinces of Canada while subtropical ridge remains in the southwestern Atlantic, Bahamas into the eastern Gulf of Mexico to FL Peninsula. Stronger spoke of energy in the base of the trough axis yesterday is now centered over the Mid-South & progged to lift to the northeast through the day today. Expect another day of active convection, with an early start ongoing southeast of the Natchez Trace corridor. Light propagation, >90th percentile precipitable water (PWs)/tropical airmass & deep warm cloud depth >15kft, support slow-moving tropical downpours with localized flash flooding. HREF prob match mean have lowered but there remains some indication of potential for heavy rain mainly along & south of a line from along the I-55 corridor in Grenada to Yazoo in Warren in MS & westward to just south of the I-20 corridor in Madison, Tensas to Franklin parishes in LA. In the wake of the stalled boundary, there is some drier air around or < 1.5 inch PWs. This potential will persist into the rest of the weekend. Temperatures will remain seasonably cool today in the mid-upper 80s, with seasonable lows in the low 70s this morning & again tonight. Heat stress will remain in check today, but heat indices will be a touch warmer in the mid-upper 90s, especially across the southern half of the area. Some patchy fog is possible in areas this morning & again into tonight, especially in areas that receive sufficient rainfall. There remains scattered HREF probs for dense fog across the Gulf Coast region but remains low confidence due to ongoing cloud shield/stratus & redevelopment expected again in the I-59 to Hwy 84 corridor tonight. Light westerly flow could organized some storms into some isolated strong storms, severe storms are not anticipated. /DC/ Sunday through next Saturday... Not much has changed throughout the long term period as we remain in this stagnant pattern of rain with tropical moisture and multiple rounds of shortwave energy flowing into the southeastern states. Upper level troughing will persist through the mid/lower MS Valley through much of central CONUS. This frontal boundary will often be influenced by rounds of shortwave energy of a low pressure system as it makes its way through the Mid-West to Great Lakes and adequate moisture transport, diurnal heating and increased convergence from boundary lifting to the northwest. With this current weather regime pops will continue to be scattered to numerous in coverage with some areas of heavy precip but generally much of the same day-to- day throughout the period. Areas have been seeing rainfall totals upwards of 2in constantly and the limited flash flooding threat will remain in the graphical HWO for a majority of the CWA through this weekend as some areas could see upwards of 2-4in of rain, with locally higher amounts. Pops have been adjusted slightly as the best moisture profiles trend further south/southeast. Thus, portions of the ArkLaMiss region will have been trimmed out of the flash floor threat graphic. As for heat, consistent cloud cover and rain chances will keep the heat in check keeping max temps well below climo for this time of the year. /KVP/ && .AVIATION... (06Z TAFS) Issued at 206 AM CDT Sat Jul 20 2024 Deep moisture across the region is fueling ongoing scattered SHRA, near JAN & HKS & mainly focused at PIB & HEZ through 20/11Z & at MEI between 20/09-14Z. A rumble of TS is psbl through mid- morning. Low stratus & patchy BR are developing & ceilings will only worsen between 20/08Z-16Z this morning. MVFR-IFR ceilings are expected & as low as LIFR at PIB & HEZ. The best chance for scattered-numerous SHRA & TSRA will be 20/19Z Saturday to 21/01Z Sunday. Aftn SHRA & TSRA will wind down by 21/02-03Z. Winds will be light & variable, below 10mph, through the TAF period. /DC/ && .PRELIMINARY POINT TEMPS/POPS...
