.MESOSCALE UPDATE... Issued at 926 AM CDT Wed Oct 8 2025
The dense fog has lifted and the Dense Fog Advisory was allowed to expire at 9AM. A narrow band of showers that was nearly along and just south of Interstate 20 this morning has also dissipated but there will remain very low chances of rain across our southern zones this afternoon as a weak cold front continues to drop through the CWA. This dry cold front was noted along the highway 82 corridor at mid morning. This cold front will continue to drift through the CWA through this evening. /22/

.DISCUSSION... Issued at 244 AM CDT Wed Oct 8 2025
Today and Tonight...
Early morning CAM guidance is still showing low probabilities (20- 30%) of dense fog development primarily over east and southeast portions of the area this morning. Because of this, a "Limited" threat for dense fog will continue to be advertised. Any fog should lift and dissipate by mid-morning.
Near term guidance continues to show the weak cold front shifting southward across our CWA. A few scattered showers and storms cannot be ruled out mainly for areas south of Hwy 84 later this afternoon. Elsewhere, weather conditions will remain relatively quiet. Afternoon highs will peak into the low/mid 80s areawide.
Thursday through Wednesday...
The weak cold front will continue to shift southward and eventually out of our CWA heading into Thursday. With the cold front out of our area, there will be a noticeable decrease in both moisture and humidity. This will limit rain chances and allow for quiet and drier conditions across the southeast CONUS through the rest of this week and into early next week. While daytime temperatures will remain close to normal, nighttime temperatures will cool a little more in the drier air than they have recently. /CR/
