.KEY MESSAGES...
Updated at 103 PM CDT Thu Oct 8 2026

- Dry weather continues through the weekend with near to slightly warmer
  than normal temperatures.

- No significant rain chances through the weekend and possibly
  into early next week. 

&&

.SHORT TERM...
(Tonight through Friday night)
Issued at 1222 PM CDT Thu Oct 8 2026

Not much to write about in the short term as we remain in a very
dry pattern with plenty of sunshine expected across the area. We 
should continue to see high pressure dominate resulting in highs 
in the low 90s which is slightly above normal for this time of 
year. With this dry air, dewpoints will continue to feel 
comfortable with many feeling the 50s to low 60s. Compare this to
last weekend when we had dewpoints in the mid to upper 70s, this 
results in a much more pleasant day. We will also continue to see 
cool mornings as this dry air allows lows to drop into the low to 
mid 60s each night. 

&&

.LONG TERM...
(Saturday through next Thursday)
Issued at 1222 PM CDT Thu Oct 8 2026

Similar to the short term, the extended portion continues to 
feature plenty of sun, above normal high temperatures and 
relatively comfortable mornings. This changes by Sunday as a
dry trough moves over our area. As this happens, we then begin to
lose the influence of the high pressure over us with a return to 
onshore flow. This likely means the return of humid days along 
with warmer high temperatures. While onshore flow returns by 
Sunday many across the area likely won't feel the true effects of 
this flow until Monday. By that point we could be looking at highs
in the low to perhaps mid 90s. Add in the increasing moisture and
we could see heat indices close to 100 degrees and even 
approaching 105 degrees by middle of next week. Enjoy the upcoming
pleasant days through the first half of this weekend as warm and 
humid days look to once again make a return across the area.
