Marine Weather and Tide Forecast for Dardanelle, AR

DISCUSSION
Issued at 127 AM CST Tue Jan 20 2026

To begin the period, calm and dry conditions are expected Tuesday as surface high pressure takes control of the weather pattern. The frontal boundary that moved through yesterday has ushered in drier air meaning min RH values Tuesday afternoon are forecast to drop into the 20s. With surface winds out of the south around 5-10 mph and gusts slightly higher...an elevated wild fire danger will once again be possible Tuesday afternoon.

The pattern will begin to break down again late Tuesday into Wednesday as another disturbance is expected to track across the state. This will bring increased rain chances across portions of central and southern Arkansas. With that said, a complete washout is not expected and rainfall totals are expected to stay below half an inch. Highest rainfall amounts on Wednesday will likely be across southern Arkansas.

Another period of calm weather is expected Thursday as the frontal boundary pushes away from the state. This will once again be short- lived as the next storm system will affect the state Friday into Sunday, bringing the chance for widespread winter weather.

Model guidance continues to suggest accumulating snow and/or freezing rain are possible across much of the state Friday through early Sunday. This along with plummeting temperatures could create hazardous road conditions this weekend and into early next week.
While it is still too early to pin-point exact snowfall totals right now, one thing is for sure...the ingredients and model data trends supports the idea of a winter storm affecting much of the state later this week.

With that said, models continue to diverge some on exact timing and precip type for parts of the state so forecast details are still likely to change over the next couple of days. However, now could be a great time to start preparing for wintry precip later this week as it continues to look more and more likely for the state.

Temperatures will continue to be average to slightly below average early in the period with highs in the lower 40s to upper 50s and overnight lows dropping into the lower 20s to upper 30s.

As we transition to Friday and the weekend...temperatures are currently forecast to become dangerously cold as cold air from Canada pushes south Friday and lingers into early next week. This will be in conjunction with the moisture associated with the weather system meaning the cold air could be in place as the moisture tracks across the state. All this to say, if the snow falls as currently forecasted there could be a period between Friday to Monday afternoon where many locations around the state struggle to get above freezing at all. Even overnight temperatures could drop into the single digit and teens.

However, nothing is set and forecast details could continue to change has updated data continue to arrive. Please check back over the next few days for the latest and most up-to-date information.
