DISCUSSION.
For the 20/06Z TAF Issuance.
AVIATION.
For the remainder of the night, light winds, stable conditions, and just some left over high level cloudiness, will set the stage for some patchy fog, especially locations that received rainfall and with wet grounds. Visibilities will be mainly in the MVFR range. Any fog that forms should dissipated shortly after sunrise. Scattered showers and thunderstorms will be possible again during Monday afternoon.

PREV DISCUSSION. /issued 905 PM CDT Sun Sep 19 2021/
UPDATE . Diurnal convection has dissipated with the loss of daytime heating. Expecting some nocturnal shower activity to develop over the coastal waters before daybreak, and mainly stay over the coastal waters. With clearing skies, light winds, and some wet grounds, patchy fog can be expected during the overnight. Currently forecast is on track and no significant changes planned at this time.

PREV DISCUSSION . /issued 404 PM CDT Sun Sep 19 2021/
DISCUSSION . SHORT TERM [Tonight through Tuesday Night] An upper level disturbance continues to sit across the northern gulf this afternoon providing support for scattered showers and thunderstorms. With PWAT values hovering around 1.8, some of these storms have been producing very heavy rainfall that has led to some isolated areas of street flooding. Despite the upper level support, virtually all short range guidance shows the convection dissipating around sunset this evening.
Very weak pressure gradient overnight will allow winds to calm with models once again showing a pretty good fog signal early Monday morning. Added patchy fog wording for the 09 to 13Z time frame as fog should dissipate quickly beneath clear skies.
The previously mentioned upper level feature will retreat to the north Monday and become absorbed by a digging upper level trof. This will leave the region within a broad weakness, but diurnally driven convection is expected to be less widespread than that being seen this afternoon.
Tuesday will see another round of afternoon convection, but the bigger story will be the approach of the first significant cold front of the season late Tuesday evening. The front will be accompanied by a semi-organized line of heavy rain producing convection, but the vast majority of these are expected to remain sub severe.
LONG TERM [Wednesday through Sunday] .
The start of the long term period will herald a much awaited change from the recent wet weather pattern. By Wednesday morning, a cold front is expected to be well east and south of the area, with northerly winds ushering a cooler and drier airmass into the region. Aloft, a deep longwave trough axis will extend acrs IL southward acrs the lower MS Valley. An amplified pattern with a mean trough over the eastern CONUS and ridging over the southern Rockies will keep a dry northwesterly flow aloft over the region through the bulk of the long term period.
Any lingering showers early Wednesday morning should quickly end as drier air filters into the region. A markedly drier airmass should stick around through the end of the week and into the weekend, with precip water values between 0.5 and 0.7 inches Thursday and Friday (by comparison, typical normal PW values are between 1.43 and 1.48 inches per SPC Climatology). Sfc high pres building over the region will provide a northerly flow through the end of the week, with the ridge axis expected to settle over the region by next weekend, allowing temperatures and moisture levels to moderate some.
High temperatures on Wednesday will be about 10 degrees cooler than highs on Tuesday with max temps expected to top out only around 80 degrees. Overnight lows will be generally in the mid to upper 50s acrs much of the area Thursday and Friday mornings, with highs near 80. A gradual moderation in temperatures will occur into next weekend, but temperatures should remain below late September normals with comfortable and pleasant conditions expected.
