DISCUSSION

Issued at 1105 PM CST Wed Nov 5 2025

Another quiet and clear night across the Four State Region following a rather warm afternoon as highs approached and even exceeded 80 deg F. It will be a rinse and repeat theme heading into Thursday as highs will be very similar to this afternoon. Before we get there though, dense fog will be the weather focus through the early morning hours of Thursday and through the morning commute as the potential for low visibility will cover a good majority of the southern zones of the forecast area.

Given the potential for visibility at or below a quarter of a mile, a Dense Fog Advisory was issued this evening, and is set to go into effect at 3 AM CST Thursday morning. It is worth mentioning that areas north of the advisory zone, meaning along the I-20 corridor and north, will have the potential for patchy fog, and isolated instances of dense fog, but the confidence for widespread impacts was not high enough to justify bringing the advisory further north at this time. If this changes, an expansion in the advisory will be made. For now though, the advisory is set to be in effect until 9 AM CST Thursday. Hi-res solutions this evening have been consistent with the fog burning off through mid morning, with a return to clear skies by the afternoon.

Looking through the end of the week, model surface vorticity output continues to highlight a common theme in that weak surface boundaries approaching the FA will either stall out, wash out entirely or not reach the region at all. At the same time, confidence continues to grow that the eastern portion of the FA will miss out on rain chances completely as moisture displacement and sufficient forcing will be mostly east of the region Friday afternoon, with the focus for showers and storms highlighting the ArkLaMiss vicinity and areas east.

The real weather story in the long term is the chance for some of our coldest temperatures of the season as a shot of cold air races southward Sunday night and into Monday AM. Base long range NBM continues to suggest lows in the upper 20's and low and mid 30's across the region Monday AM, with similar lows for Tuesday AM. For now, Monday AM looks to be the coldest of the two nights, and something to monitor as some of the area climate sites may see their first chance at temps near freezing for the first time this season. Though rain would be welcomed with the late weekend frontal passage, we know that these stronger fronts can increase severe potential at times. The good news is that the boundary looks to be dry, and no severe potential is expected.

AVIATION

(06Z TAFS) Issued at 1105 PM CST Wed Nov 5 2025

For the 06/06z TAF update...Surface observations from non-TAF sites are starting to show some lower visibility in spots across southwest Arkansas and deep east Texas. The only terminal that has been dropping so far has been KELD. That being said, I think we will continue to see patchy to areas of fog as we move towards Thursday morning and have mention of such for all terminals. Visibility will reduce visibility to 1 mile or less at times and the terminals I think will be most impacted by this are KMLU, KELD, and KLFK. The fog should begin to lift after sunrise and things will gradually return to SKC VFR conditions. Winds are expected to remain under 10 kts throughout this TAF period. /33/
