Area Forecast Discussion National Weather Service Jackson MS 352 PM CDT Fri May 3 2019 .DISCUSSION... For late afternoon through Saturday: Perturbations in deep southwest flow aloft ahead of a shortwave trough slowly crossing the Southern Plains continue to initiate episodes of showers/storms in a moist and unstable airmass. Currently, we are seeing weakly organized convection develop along/south of the Highway 84 corridor during peak heating, but expect a more robust convective system to potentially develop during the evening and affect mainly northwest portions of the ArkLaMiss per consensus from CAM guidance. The most significant storm threat will culminate in slight severe weather risk from late Saturday morning into the afternoon as the primary shortwave trough moves into and across the ArkLaMiss region. Not much has changed concerning the severe weather outlook. We expect the combination of deep layer shear/instability to support a robust organized convective system capable of producing severe wind gusts. It is possible the most intense convection will tend to be suppressed, and could push through a bit faster owing to an over-achieving cold pool and confidence is somewhat low in this regard. Have continued the severe weather threat depiction in the HWO/graphic with just slight modifications for coverage/timing for now. /EC/ Saturday Night through Friday: Forecast soundings show the atmosphere should stabilize quickly in the wake of afternoon storms, so the severe threat is not expected to continue into the overnight hours. In the wake of this system, a more stable post-frontal air mass will settle into the Southeast, although a few showers or thunderstorms will be possible closer to the Gulf Coast where the front stalls out. Temperatures will still be near normal on Sunday, as clearing skies allow the air mass to modify quickly. Then expect a quick rebound to mid- and upper-80s high temperatures on Monday as the combination of southerly flow and shortwave ridging aloft boost max heating potential across the region. The rest of the week still has some uncertainty regarding timing and location of best shower and thunderstorm chances, but the establishment of a trough/ridge pattern across the CONUS will keep the potential for one or more shortwaves to move across our region throughout the week. The GFS is more quick to bring a shortwave through again on Tuesday, while the ECMWF and CMC remain slower and less amplified with development of that shortwave so have kept POPs topped out around 40 to 50 percent with that system for now. A surface frontal boundary is expected to set up across the Plains and Midwest, and ongoing rain along this boundary could help it to dip further south into our forecast area than models currently indicate. This will result in increasing chances for heavy rain to affect portions of our area by the middle to later parts of the week. Model guidance suggest another 2 to 3 inches of rain could fall during the second half of the week, but we will continue to monitor overall trends should this signal shift southward with time. Although no organized threat for severe weather exists with any particular system for next week, steeper lapse rates and potential for good daytime heating around the periphery of the ridge will increase chances for damaging wind gusts with any stronger storms throughout the week. /NF/ && .AVIATION... 18Z TAF discussion: Although VFR conditions will prevail for much of the area this afternoon, the forecast is complex over the next 24 hrs with a few periods of SHRA/TSRA expected over northwest portions of the forecast area where the synoptic scale lift will be most supportive of periodic thunderstorm systems. Coverage should be a bit more scattered to isolated over southern/southeast portions of MS. In addition, another late night/ early morning episode of IFR/LIFR stratus is expected with ceilings lifting some during the late morning. /EC/ && .PRELIMINARY POINT TEMPS/POPS...
