926 FXUS64 KJAN 070548 AAC AFDJAN Area Forecast Discussion...UPDATED National Weather Service Jackson MS 1248 AM CDT Fri Jun 7 2024 ...New AVIATION... .DISCUSSION... Issued at 151 PM CDT Thu Jun 6 2024 Today and tomorrow: A front is moving through the region this evening and will help usher in a slightly drier airmass into the ArkLaMiss. This will mark the end of the current wet pattern we had this week. As the front moves through this evening there is only a small chance of a shower across southeast Mississippi but those rain chances should be fairly small and should end later this evening. Expect warm and sunny conditions for Friday and Saturday as temperatures remain in the lower 90s through Saturday. /MJH/ Friday night through next Thursday... By Friday night into the weekend, deep layer ridging will strengthen as a high pressure sits over the Southern Plains. Mid-level ridging will influence northwesterly flow into the southeast region, promoting the continuance of a dry, continental airmass over the CWA through the weekend. Temperatures are expected to remain in the lower 90s on Saturday and upper 60s to lower 70s overnight. By Sunday, the high pressure is expected to migrate eastwards over the Lower Mississippi Valley, allowing for temperatures to become maximized. Highs on Sunday will range in the middle 90s for most of the CWA, while some areas in the Pine Belt potentially reaching the upper 90s. The main concern will be heat indices, as some areas may reach up to 105 degrees. As of now, no heat products are being advertised but we will continue to monitor the potential as certainty increases. A low pressure system progged to move eastwards out of the High Plains is expected to bring a weak trough just north of Mississippi. Increased moisture from this system and efficient afternoon heating looks to bring a chance for isolated showers and a strong storm or two along and north of the Hwy 82 corridor on Sunday afternoon. Otherwise, expected hot and dry conditions to prevail. By Monday into the middle of the week, southerly flow looks to prevail, which will keep moisture in the lower levels through midweek. Models guidance continues to have uncertain regarding precipitation amount and timing through the end of the period. Any chance of precip looks to be isolated to scattered in nature and the severe potential seems to be fairly low. Temperatures will be near normal, with highs in the middle 80s to low 90s and lows in the middle 60s. /AJ/ && .AVIATION... (06Z TAFS) Issued at 1240 AM CDT Fri Jun 7 2024 Some shallow BR or FG cannot be ruled out before 12Z, but the arrival of drier air from the north should limit those chances. Otherwise, VFR conditions with north winds less than 10 kts should prevail through the TAF period. /NF && .PRELIMINARY POINT TEMPS/POPS...
