.DISCUSSION...

Issued at 239 AM CST Thu Nov 5 2026



An upper level low over the Great Lakes will continue to

progress eastward while an upper level ridge over the Northern 

Rockies continues to amplify. Northeasterly surface flow is 

currently propagating low stratus across the central and eastern

half of the state. Low stratus is forecast to break up later 

this afternoon as northeasterly flow switches to southeasterly

and solar insolation burns off the westerly extent of the low 

stratus. Although, some low stratus may linger in the James 

River Valley to the Red River Valley. Some patchy to areas of 

fog is possible across the northwest as temperatures near the 

dew point with little to no wind. Fog may be dense at times. 

Patchy fog will burn off after sunrise. High temperatures are 

forecast to be around the upper 30s east due to the low clouds 

and the lower 50s out west due to the proximity of the upper 

level ridge. Overnight low temperatures are forecast to drop 

down into the 20s.



The upper level ridge will pass over the Northern Plain Friday  

bringing back above normal temperatures in the 50s out west 

while the east is forecast to be in the 40s. Temperatures are 

forecast to warm up into the 50s and 60s Saturday as the thermal

ridge moves over the region and compressional warming ahead of 

a frontal passage. Upper level ridging will move eastward this 

Saturday as an upper level low digs across the International 

border. The aforementioned upper level low will bring forth 

windy conditions across the western and central half of the 

state as westerly winds aid the warmer temperatures Saturday 

afternoon. No precipitation is forecast from this upper low. 

Ridging will build back over western CONUS Sunday, but an upper 

level wave will dampen the ridge Monday leading to windy 

conditions with another frontal passage. Upper level ridging 

will then amplify over western CONUS by the middle of next week 

bringing above normal temperatures and dry conditions.
