KEY MESSAGES

Updated at 725 PM EDT Sat Apr 11 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 114 PM EDT Sat Apr 11 2026

Very little has changed regarding the forecast for the next week. A large high pressure ridge across the Southeast will be the dominant feature, providing dry and warm conditions. A series of low pressure systems will cross the Plains and Great Lakes, but the strength of this ridge will prevent any precip from reaching our area until perhaps late next week when the ridge shifts off the Atlantic coastline.

The main weather concern for this period will be fire weather conditions. As high temperatures warm into the 80s, afternoon RH values will drop into the 20s. Winds will increase tomorrow to around 10-15 mph with gusts around 20, then increase again on Monday, 10-20 with gusts 25-30 mph, aided by channeling of SW winds up the TN Valley. Monday will have some cloud cover, which may aid in keeping RH values from dropping below 25%. Fire weather interests should stay aware of these conditions setting up for Sunday and Monday, and potentially Tuesday and Wednesday as well.

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 the TN Valley 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.

AVIATION

(00Z TAFS) Issued at 725 PM EDT Sat Apr 11 2026

VFR flight categories are expected through the period. ISOLD SHRA INVOF KTRI are waning quickly at the moment and should be gone by the time the 00z TAFs are valid. Don't see any SHRA potential tomorrow at any sites as instability will be more limited. Winds will pick up however as pressure gradients and overall wind field strengthen. Have gusts to 20kt in at both KTYS and KCHA.
