Marine Weather and Tide Forecast for Eureka Springs, AR

SHORT TERM
(Through Sunday)
Issued at 1030 PM CST Sat Nov 7 2026

It is another chilly night across the region with high pressure and light winds producing effective radiational cooling. Lows in the 30s are expected across NE OK and NW AR, with low 40s near the Red River. A brief freeze is possible in the typical cold drainage locations, though this will depend heavily on fog development. At least patchy fog is possible areawide overnight, though the greatest coverage and potential for significant visibility reductions are expected along and north of I-40.
Anywhere that remains fog-free is likely to experience the coldest temperatures. Frost will also be a concern and a Frost Advisory is in effect from midnight through 9 AM.

Any fog is likely to burn off by mid-late Sunday morning with mostly clear skies expected during the day. Temperatures will recover nicely into at least the mid-upper 60s areawide. With winds remaining light, it should be a pleasant fall day for the local area.

LONG TERM
(Sunday Night through Saturday)
Issued at 1030 PM CST Sat Nov 7 2026

Overnight lows will be a tad warmer Sunday night, though still below average. Fog development will once again be possible across NE OK and NW AR. By Monday, high pressure will be sliding east, with southerly low level flow returning to the forecast area. This will promote a warming trend into mid week, with highs warming into the mid 70s Tuesday and Wednesday. An upper level low will move east across N TX Tuesday, potentially leading to a few isolated showers across SE OK, but any rainfall likely remains negligible. Then, on Wednesday, a shortwave will drop southeast through the central Plains, perhaps leading to some low rain and storm chances across far E OK and NW AR. From here, a pair of cold fronts are projected to sweep through the region with deep troughing developing over the eastern US and ridging to our west.
Dry northwest flow aloft and post-frontal high pressure are likely to keep conditions dry and seasonably cool through the weekend.
