NWS Jackson, MS wrote its last area forecast discussion before the first event at Dec 12, 12:03 AM CST, 57 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Jackson MS 1203 AM CST Thu Dec 12 2019 .UPDATE... Updated for 06Z aviation discussion. && .AVIATION... 06Z TAF discussion: VFR conditions and light winds to begin the TAF period, with increasing stratus deck expected to begin affecting the Pine Belt by around 15-18Z today. Deck should eventually lower into the MVFR range, and could reach all but the KGWO and KGLH TAF sites before 06Z Friday. Some -SHRA may occur mainly near KHBG and KPIB after 18Z. /NF/ && .DISCUSSION... The forecast is generally on track with the only adjustment being to lower temperatures a bit based on evening trends as clear skies and light wind are making for ideal nighttime cooling in the dry airmass. Otherwise, no significant adjustments were necessary for this update. /EC/ Prior discussion below: Tonight through Friday Night: A split flow regime then sets up across the CONUS with the southern stream sitting across AL and the northern stream across the Great Lakes region. Cloud cover begins to increase through the day tomorrow as a shortwave rides along the southern stream to our south and east. While the bulk of the rain will miss the CWA to the east, cannot rule out showers after midnight tomorrow into the morning Friday, especially along and east of I-55. Best chance of rain is in the afternoon Friday as model guidance shows a deep trough building across the central CONUS with a disturbance riding along the bottom of the trough. This will provide increased lift across the area and hence, rain Friday night. /GH/ Saturday through Tuesday: A southern stream system lift a sfc low from the northern Gulf and pull it northeastward on Saturday. This could could bring a few showers, but the majority will be to our NE. The system will phase with a northern system Saturday afternoon and deepen the low as it slides up the East coast. Northwesterly flow will set up behind the departing system and bring slightly cooler temps overnight with lows dipping into the upper 30s to lower 40s. As the next system digs into the Four Corners on Sunday, southwesterly flow aloft will set up and the development of a sfc low near the ArkLaTex that will return southeasterly flow. This will warm temps up into the 60s and return ample moisture to the region. As the sfc low lifts NE and the trough swings through the Southern Plains, showers will spread across the forecast area on Sunday, increase in coverage Sunday night and become numerous on Monday. Models are not in agreement on the track of the sfc low with the GFS showing a more sharp NE track while the ECMWF moreso lifts across MS. Stuck close to the model blends for this system until better agreement is seen. WAA could push daytime highs on Monday into the 70s across the southern portion of the forecast area. Could see isolated thunderstorms Monday afternoon and evening with better lift ahead of the cold front. As the cold front pushes through the forecast area, precip will taper off from W to E Monday night. Much cooler and drier air will filter in behind the front. Overnight lows on Monday will only be in the 30s and Tuesday will be in the mid 40s to lower 50s. /JMS/ && .PRELIMINARY POINT TEMPS/POPS...
