.DISCUSSION...
Issued at 133 AM EDT Mon Oct 26 2026

Currently, ridging is centered just to our west with surface high 
pressure across the eastern U.S. This pattern will continue 
subsidence and promote a cool morning today, followed by mild 
daytime highs in the 70s. Efficient mixing will allow for RH values 
to drop into the 30s area-wide, but thankfully a weak MSLP gradient 
will keep winds very light. By Tuesday, the ridge will move over the 
region, causing height rises and temperatures rising further into 
the 70s. With even more efficient mixing, lower RH values into the 
20s are likely for some. The pattern will be similar again on 
Wednesday with some suppression of the ridge to our east, leading to 
a very slight drop in daytime highs. By Thursday, the flow will 
become more zonal aloft with similarly mild daytime highs expected. 

By Friday, a shortwave will eject out of the Rockies with additional 
ridging expected over our region downstream. Surface high pressure 
and will keep conditions similar to previous days. For Halloween, 
the ridge will push off to our east as the shortwave approaches from 
the west. Depending on moisture advection and evolution of the 
shortwave, rain chances will return but currently look to be more 
towards Sunday or later.
