Area Forecast Discussion National Weather Service Little Rock AR 550 PM CST Mon Jan 27 2020

AVIATION. A stationary front is across north Arkansas this evening. A low pressure system with a cold front is in north Texas and will move toward Arkansas tonight and Tuesday. This will bring an increase in moisture and rain chances during the day Tuesday. Fog, dense in some locations, is again expected in the morning before the rain arrives. Rain is expected for the last quarter of the period. VFR conditions will become IFR and LIFR in the morning.

PREV DISCUSSION. (ISSUED 250 PM CST Mon Jan 27 2020) Short Term . Tonight thru Wednesday . Low clouds and fog that were present across much of the state finally burned off in most areas by midday, although low clouds are still lingering across portions of southwest AR at this hour.

The next big storm system is over the AZ/NM border area, and can be seen quite clearly on IR/WV imagery. This system will spin up a surface low over northern TX later tonight, and this will start to bring increasing low level moisture to the area late tonight thru tomorrow. I will continue with rain chances starting across the area tonight, and will increase rain chances notably tomorrow.

The main concern all along has been the potential for wintry weather across portions of northern AR tomorrow night thru Wednesday morning. For once it appears that freezing rain will not be a concern, so more than likely we will be dealing with rain, snow, and a rain/snow mix. Regarding the latest model trends, I think the bulk of the wintry precip will fall as a rain and wet snow mix, and relatively little will accumulate. Some areas, notably the higher terrain, may trend more toward all snow by Wednesday morning.

Despite that, I am not seeing much accumulation across northern Arkansas with this, mainly a tenth to perhaps a quarter inch of snow, with most of that in the higher elevations.

On a final note, it appears that last night's low clouds and fog will make another appearance over the area tonight, with the densest fog in the valleys. I am not too confident that the fog will be very widespread and dense across northern AR as it was last night, however there may be some dense fog over the larger lakes and river valleys. That said, the bulk of the fog will likely be over the southern two-thirds of the state, and I anticipate the densest fog may be from Little Rock to the east-central part of the state.

Extended Term . Wednesday Night thru Monday . Fairly quiet weather conditions expected through the long term portion of the forecast with little to no mention of precip. The H500 flow aloft will initially be out of the southwest but a transition to northwesterly will occur in the wake of a shortwave trough moving expected to progress over the area Friday.

Cooler conditions initially will be influenced by surface ridging in place north and east of the area, but as upper level and surface ridging build across the west, warming temperatures will be seen. Temperatures across the west could warm to near 70 F Sunday and Monday. Just beyond the long term portion of the forecast, a more robust upper level system may move through the region.

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.
