DISCUSSION
(Wednesday through next Tuesday) Issued at 1047 PM CDT TUE OCT 20 2026
Dry northwesterly to northerly flow aloft persists through Thursday, between ridging over the Southern Plains and troughing along the East Coast. At the surface, high pressure over the eastern CONUS maintains a dry continental air mass, while a surface low moves slowly northeastward off of the Mid-Atlantic/Northeast coastlines. Cool nights and temperatures near to slightly above average are expected with no rain. Friday through the weekend the low pressure system over the western Atlantic exits, while a cutoff low forms near Cuba. This allows the mid-level subtropical ridge to build eastward, but a strengthening CAD wedge in the wake of the Atlantic system results in slightly cooler high temperatures for the weekend. A shortwave trough approaches the area next week, but little to no moisture return is indicated at this time as high pressure persists at the surface.
