.PREV DISCUSSION... /Issued 216 PM CDT Fri Oct 30 2020/

DISCUSSION...
Current satellite and model analysis depicts an upper-level high
centered over the Texas coastline with a ridge extending
northwestward over the FA into southeast CO. This ridge will
flatten tonight with flow aloft becoming mostly zonal as a
shortwave trough digs into the northwestern CONUS. By Saturday
night the base of this trough is progged to skirt just north of
the FA. There will be a weak surface cold front to pass through
the FA Saturday night associated with this upper level shortwave
trough. This current forecast does not contain any precipitation.

Visible satellite still shows some snow on the ground mainly along
the south side of the Canadian river valley and some north of in
Moore, Sherman, and Hansford County the time of this writing.
This snow will help hold back temperatures in these areas today
despite the plentiful solar radiation with mostly clear skies.
Other areas without snow are already warming considerably with the
help of downsloping winds, as of this writing. Have raised
temperatures today and tomorrow, due to the NBM having a cold bias
from last weeks temperatures. Overnight winds will stay up in the
10 to 15 mph range in the southern Texas Panhandle allowing
temperatures to stay around 40 while places such as the northwest
FA will dip into the upper 30s with less mixing and more
radiational cooling occurring. For tomorrow, southwesterly to
westerly downsloping winds will help temperatures warm to above
normal by about 3 to 5 degrees.

Saturday night a cold front will move through the area dropping
temperatures to around freezing or just below for the northern half
of the FA, while the south will be just above freezing in the 30s.
Daytime temperatures will be cooler on Sunday with temperatures
expected to be below normal by 5 to 7 degrees. Late Sunday an
upper level ridge builds back over the area creating a warming
trend going into the extended period. By Wednesday and Thursday
daytime temperatures will be above normal for the beginning of
November.
