UPDATE.

Updated to include the 12z aviation discussion.

AVIATION.

IFR/LIFR conds prevail this morning due to low stratus. Patchy FG will be possible near sunrise, however FG and CIGs should lift by mid-morning to MVFR then VFR by the afternoon. Scattered SHRA/TSRA will be possible today as moisture from the remnants of Nicholas affect the state. Precipitation should decrease in coverage after sunset this evening. Winds will be out the E/SE at around 10 knots or less. CIGs are once again expected to lower Sunday night, and MVFR conds return.

PREV DISCUSSION. (ISSUED 416 AM CDT Sun Sep 19 2021) SHORT TERM . Today Through Monday Night

Currently, scattered showers were noted over portions of N-Cntrl AR and Ern AR via LZK radar. Through the early morning, this activity is expected to increase in coverage, especially across Ern half of the state. Low-stratus is also expected to continue developing and expanding in coverage spreading from SE to NW through sunrise. Additionally, patchy fog is anticipated to develop near sunrise over portions of Cntrl AR, mainly in areas that received beneficial rainfall on Saturday.

A weak cut-off low was located over Nrn LA this morning, removed from the main steering flow found across the Nrn CONUS. Through the course of Sunday, this upper low will begin a Nwrd trek over AR ahead of a deepening trough over the Rockies. On Monday, the aforementioned upper trough will quickly sweep across the Nrn Plains. As this happens, the upper cut-off low will phase with the trough and eject into the OH Valley region.

Showers and thunderstorms are expected to develop over the Ern half of the state by mid/late morning, spreading N and W during the day into the afternoon time frame. Highest PoPs are expected towards the MS River and/or towards the LA border. QPF amounts will vary greatly depending on were thunderstorms develop and track, but overall, amounts of a quarter of an inch to half an inch will be possible. Highest QPF will reflect PoP trends with amounts decreasing towards the N and W.

Drier weather is expected on Monday as the system lifts N of the state. To the W, a surface cold front will develop and begin moving across the Cntrl Plains. This front will not move across the state until Tuesday, but in the mean time, moisture will advect into the region ahead of advancing cold front. Weak subsidence aloft will limit PoPs to Ern AR on Monday afternoon.

LONG TERM . Tuesday Through Saturday

Much talked about CDFNT wl be entering the FA fm the NW at the start of the PD. As the bndry progresses to the SE, showers/storm wl bcm likely ahead of the FROPA. Models cont to be in reasonable agreement with the front clearing the region later Tue night.

Highlight wl cont to be the much cooler and drier airmass that wl advect into the Mid-South by midweek. Sfc high pressure wl keep tranquil conds in place thru late in the work week, although a gradual moderation in temps wl occur. NW flow aloft wl bring another weak fntl bndry into the area on Sat. Contd with a dry fcst attm due to the lack of sig moisture return ahead of the bndry.

LZK Watches/Warnings/Advisories. NONE.
