Area Forecast Discussion National Weather Service Little Rock AR 250 PM CST Sat Dec 14 2019

SHORT TERM. Tonight Through Sunday Night

Cold front bisects the state from northeast to southwest early this afternoon with lower ceilings to the northwest along with temperatures in the 30s and 40s. Surface ridging will briefly try to build in to the state but will largely remain to the north of the area. The flow aloft will remain out of the northwest and dry conditions will persist through daybreak with temperatures expected to fall into the 30s and 40s.

For Sunday, the flow aloft will transition from zonal to swrly ahead of an approaching H500 trough. At the surface, ridging will quickly move north of the area and low pressure will begin to track from west Texas toward AR with a warm front extending out ahead of it. Temperature forecasts over the next 36-48 hours will be tricky and prone to frequent revisions as the location of the surface low and associated fronts will greatly influence surface temps.

As lift increases ahead of the arrival of the H500 trough, widespread low clouds will be seen and drizzle will be possible across the area. Much of the potential for rain and isolated TS development will hold off until Sunday night with the best chances on Monday. By then, temperatures in the 60s F may only briefly make it 3 rows of counties deep across southern Arkansas. Td values of 60 F may only be seen across a handful of counties in SE AR. With all this said, and with the assumption that adequate lift and shear are present, the areal extent of a severe weather threat is extremely limited in time and space across the forecast area.

As the trough begins to swing east on Monday, precip will begin to taper off from west to east and cooler air will build in as well.

LONG TERM. Monday Through Saturday

Monday night . The cold front will continue to move southeast across Arkansas, quickly pushing any thunderstorm activity southeast of the state. Rain showers will likely linger across the far eastern and southeastern parts of the state behind the front, but the dry conveyor belt will be descending over Arkansas behind the front bringing mid level dry air and strong subsidence in quickly behind the cold front. The GFS/NAM/ECMWF all show some lingering moisture just north of the descending dry conveyor belt near the Arkansas/Missouri border and areas north. That lingering mid-level moisture will be struggling to produce precipitation efficiently as low-level dry air advection accompanies the strong cold air advection behind the front. Weak frontogenetic forcing will likely be sufficient to keep some light precipitation falling across southern Missouri and near the Arkansas border Monday night as temperatures drop . so there is a slight chance that we could see some snow mix in with the rain before dry air completely shuts off precipitation after midnight Monday night/Tuesday morning. Any light snow should be confined to the Ozarks near the Missouri border and accumulation is not likely due to inefficient precipitation production and relatively warm surface temperatures.

Tuesday through Thursday . A ridge of high pressure will build in over Arkansas mid-week keeping mostly clear skies and dry weather in the forecast through this period. Temperatures will start out cool on Tuesday, and then slowly warm into the lower to mid 50s by Thursday as winds shift around to the south and a few days of sunny skies build some heat back across the state.

Friday and Saturday . While models disagree on the timing, there is a general consensus that a strong upper level shortwave trough will move east over Arkansas, bringing our next chance of rain to the forecast Friday into Saturday . depending on the timing of the upper level trough. It will not rain the entire time period from Friday through Saturday, but there is rain in the forecast the entire period primarily due to uncertainty regarding the timing of the trough. At this time the chances for severe weather or winter weather appear to be low as there is not enough time for significant moisture return to support severe thunderstorms, and the precipitation seems to clear out before the coldest air arrives once again keeping all precipitation in liquid form. This upper trough is not expected to bring a strong cold front across the state, so temperatures are expected to remain in the mid 50s each day through the weekend.

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.
