Area Forecast Discussion National Weather Service Little Rock AR 1127 PM CST Sat Jan 18 2020

AVIATION. High pressure will continue over the area through the period. Clouds will move out of the southeast tonight and the area will be clear. North and northwest winds will remain elevated and gusty and will increase during mid morning. VFR conditions will continue.

PREV DISCUSSION. (ISSUED 524 PM CST Sat Jan 18 2020) UPDATE .

Updated to include 00z aviation discussion below.

AVIATION .

VFR conditions expected through the period. NW-N winds will be seen through the period, strongest for the next few hours.

PREV DISCUSSION . (ISSUED 234 PM CST Sat Jan 18 2020) SHORT TERM . Tonight Through Monday 20z surface analysis indicates a secondary cold front now entering extreme northwest sections of the forecast area. Precipitation associated with the primary cold front has exited southeast portions of the forecast area.

Well below normal temperatures are expected during this period. Conditions promoting radiational cooling will be maximized Sunday night. Forecasts are well above any records for the date however.

Upper level energy will approach from the north late in the period. Any light precipitation associated with this feature will occur after the period ends.

LONG TERM . Monday Night Through Saturday At the beginning of the period, an upper low will drop down through northeast Arkansas/the Missouri Bootheel Monday night and early Tuesday. While there's not much deep-layer moisture to work with, the presence of what could be a closed upper feature will likely be able to squeeze what moisture there is out in the form of light snow or snow flurries before the system quickly shifts into the southeast conus.

High pressure will shift through the region on Tuesday, with moisture increasing out ahead of the next system, which will affect the area late in the week. Speaking of that system, an upper low will develop leeside of the rockies, which will amplify the longwave pattern and send the next system toward us. This will be in the form of a deepening surface low dragging a frontal system across the Mid South region. Depending on where the low winds up/occludes, we could have rain with some embedded thunder or a brief shot at mixed wintry precipitation (which would be in the Wednesday Night/early Thursday time frame). Models continue to disagree on the placement of this feature, so for now, I took a middle ground approach with the forecast.

Once this system passes, upper flow will become quasi-zonal again, as high pressure moves through.

Through the period, temperatures will largely be below seasonal averages, moderating by the weekend.

LZK Watches/Warnings/Advisories. NONE.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
