KEY MESSAGES

- Dry weather will continue into the weekend.

- Drought continue to worsen across the region.

MESOSCALE UPDATE

Issued at 1045 PM CDT Wed Apr 8 2026

Anticyclonic flow around a surface high and mid-level ridge will continue to reinforce dry air across our forecast area through the day tomorrow. Given the dry pattern and better mixing supported by the ridge aloft, afternoon dew points were lowered to match NBM 10th percentile values which are closer in line with recent observations in peak mixing. This will push afternoon minimum RH values to around 25-35 percent across the area. This will continue a steady drying of finer dead fuels, though most vegetation is undergoing greenup across the region. /NF/

DISCUSSION

Issued at 312 AM CDT Thu Apr 9 2026

Today through middle of next week (Wednesday)...

Through this weekend: Anticyclonic flow will continue as surface and mid level ridge remain entrenched across the region. East- southeasterly return flow will lock in dry thermo profiles (PWs around 0.5 to 0.9 inches), keeping efficient mixing locked in through the weekend. Afternoon humidity levels will continue to drop to the 25 to 35 percent range daily, with light east southeast winds becoming southerly and a touch stronger on Sunday. Fire danger could become a concern. Seasonable warmth is on tap, with high temps rising into the low 80s Friday to mid 80s by Sunday while low temps in the low to mid 50s tonight while mid 50s to low 60s by Sunday morning. Dewpoints will slowly climb into the weekend but still mix out efficiently each afternoon.

Next week (Monday through Wednesday): Active longwave jet energy will be driving a convectively active pattern across the Plains, while mid level and subtropical high will keep dryness across most of the area at the start. Some showers or isolated storm or so cannot be ruled out in the northwest Delta before daybreak Monday but mostly remain dry through midweek. A frontal zone may sag into the area around midweek or just after on Thursday, with isolated to scattered showers and some storms. However, the likelihood is dwindling as the region may receive a glancing blow to even deflection of the weather system altogether. Confidence remains on the low side for beneficial rains through next week. This will only exacerbate the worsening drought and potentially an uptick in fire danger concerns. Humidity will be on the rise even with the continued drought. Seasonable warmth will continue, with high temps in the mid to upper 80s while low temps near 60 degrees in the east to mid to upper 60s in the northwest Delta. /DC/
