KEY MESSAGES

Updated at 738 PM EDT Fri Apr 10 2026

- A warming trend will continue this weekend, with above normal temperatures expected through next week. Record highs are possible next week.

- Dry weather is likely to persist through next week, worsening drought and fire conditions.

DISCUSSION

Issued at 142 PM EDT Fri Apr 10 2026

The dominant weather feature through this forecast period will be a large high pressure ridge located across the Southeast today, drifting slowly to the Atlantic coast by the end of the weekend where it will remain nearly stationary through next week. A series of low pressure systems will cross the Plains, but the strength of this ridge will prevent any precip from reaching our area as the low pressure systems get deflected around the northern edge of the ridge.

Persistent dry conditions and warm temperatures under the ridge will raise concerns for fire interests next week. As high temperatures warm into the 80s from Sunday onward, afternoon RH values will drop into the 20s and 30s. Winds will be light this weekend but increase on Sunday as a series of low pressure systems track near the Great Lakes, and SW winds in the boundary layer may be enhanced by channeling up the TN Valley - potentially 10 to 20 mph with 25+ mph gusts. Fire weather interests should stay aware of these conditions setting up for at least Sunday and Monday, and potentially the rest of next week.

High temperatures will approach or exceed records next week. We might come up a few degrees short of records on Sunday and Monday, but highs in the range of 85 to 90 will be forecast for Tuesday through Friday. Given the dry ground conditions, it would not be surprising to see temperatures higher than that, as model guidance may be underdoing daytime temperatures.
