.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.
