DISCUSSION

Issued at 221 PM CDT Wed Oct 21 2026

Tonight through Thursday Night...

Another night of quiet and dry weather is in the forecast for tonight thanks to high pressure maintaining steady control over the eastern half of the CONUS. Cloud cover will begin to increase slightly across portions of central MS and south MS from northwest to southeast later tonight with clear skies elsewhere. Sky cover will be generally clear across our whole area as we head into midnight. Nighttime lows will dip into the upper 40s/lower 50s.

Dry conditions will continue across our entire forecast area on Thursday. Expect afternoon highs to peak into the 80s areawide. Quiet conditions will persist across our CWA Thursday night under clear skies. Overnight lows will once again dip into the upper 40s/lower 50s. /CR/

Friday through Wednesday...

The forecast messaging for the long term period remains the same with no major modifications made to the overall forecast. As we head into the weekend, long term guidance is beginning to show a shift to more easterly low level flow starting early Friday morning. This shift in low level flow will result in a wedging effect around the Appalachians. This will cause a little dip in daytime highs across our CWA particularly Saturday and Sunday, with afternoon highs peaking in the upper 70s/lower 80s.

Fire weather will continue to be the primary focus over the upcoming week. Antecedent ground conditions/fuels are exceptionally dry (daily max ERCs in the 90th+ percentile) with RHs falling to 20-30 percent each afternoon and at times falling into the teens. However, winds will remain relatively light throughout this time frame, which is why we don't imminently anticipate a more critical situation worthy of red flag products. We went ahead and issued a fire wx headline regarding increased fire danger across our forecast area for this week in coordination with local forestry agencies and the U.S. Forest Service. Furthermore, the areawide "Limited" threat for fire wx concern has been upgraded to a "Elevated" threat.

Great caution is still warranted with any outdoor burning over the next several days, or it should be avoided altogether, as local burn bans continue to be added across our area. If there are any signs in later forecasts of stronger wind, messaging may need to be elevated accordingly. Dry weather conditions will continue to persist across our CWA by Wednesday. /CR/DL/
