.DISCUSSION...(Today through next Tuesday)
Issued at 200 AM EDT Wed Oct 6 2021

Fair weather again today but the upper trough that closed off
across the SE CONUS last weekend will continue moving north with
rain showers and some embedded thunderstorms arriving on Thursday
and persisting into Friday as the upper low opens up into a trough
and is ejected eastward as a longwave trough amplifies across the 
western CONUS. QPF amounts in excess of an inch are possible as 
precipitable water values spike up well above climatological 
norms.

Generally fair weather over the weekend with increasing chances 
for rain early next week as shortwave troughing ejects eastward 
from the full latitude trough across the West.
