Area forecast discussion, Jul 7, 4:31 PM CST, 11 minutes before
Area Forecast Discussion...UPDATED National Weather Service Jackson MS 531 PM CDT Sat Jul 7 2018 .UPDATE... Updated for 00Z aviation discussion && .AVIATION... 00Z TAF discussion: Convective precipitation coverage expected this evening which will affect the central and southeast TAF sites. Outside of SHRA/TSRA acidity, expect mainly VFR ceilings. Late tonight into early Sunday morning will see another round of MVFR/IFR stratus development. Expect convection to develop area wide by Sunday afternoon./17/ && .DISCUSSION... This afternoon through Sunday: Most recent CAM guidance seems to have a decent handle on the current convective scenario across the ArkLaMiss with most prevalent thunderstorm activity roughly along the Highway 82 corridor over northern portions of the area in relation to weak frontal convergence, and along the Highway 84 corridor where a mid level trough axis is having the greatest influence. In between these areas over central portions of the ArkLaMiss, instability has increased with sfc temperatures near 90 F, so expect shower/thunderstorm activity to increase there per guidance as we go into the early evening hours. The primary concerns will continue to be for locally heavy rainfall given precipitable water near to slightly above two inches and slow storm movements and have kept this mention in the HWO for late afternoon/early evening. Most parameters do not favor severe microbursts, but pulse storms will be capable of producing 30 to 40 mph wind gusts, especially in hotter, more unstable locations. Expect convection to wane later this evening with normal summer like conditions for the overnight into early Sunday morning. The environment for Sunday will remain about the same with a strong subtropical ridge centered north of the forecast area promoting perturbed, moist low-mid level southeasterly flow, albeit slightly more veered than observed today which could help to hasten inland intrusion of the seabreeze-related convection and increase overall coverage. Otherwise, expect temperatures to be near to slightly below normal in the near term. /EC/ Sunday night through next Saturday: Above average rain chances and mainly seasonable temperatures will continue through the upcoming week. Early in the week, a stout mid/upper ridge over the interior portion of the CONUS will continue to stretch across the continent. As our area remains on the moist periphery of the ridge, daily rain chances will remain above climo with primarily a diurnal theme in coverage/intensity of convection. Heading into the middle of the week, the eastern portion of this ridge will erode as an upper trough develops along the East Coast, sending another weak front southward through the Ohio and Tennessee valleys. This will likely bring an uptick in convective coverage Tuesday and Wednesday, similar to what we have seen over the past few days in a similar regime. Given the very moist airmass, localized flooding could be an issue on one or both of these days, but confidence is too low in timing/placement to add mention to the HWO at this time. The GFS is most aggressive with bringing this front southward and scouring the persistently moist airmass during the Thursday - Saturday time frame, but the Euro also depicts a downswing in rain chances especially over northern portions of the forecast area during this time frame. Rain chances could remain relatively high across South MS and Central LA as the front stalls. In spite of the front, no temperature relief should be expected. In fact with the drop off in rain chances, temps may increase back to near/slightly above normal over the end of the week, with heat indices in the triple digits more attainable. /DL/ && .PRELIMINARY POINT TEMPS/POPS...
