.DISCUSSION...(Tonight Through Saturday)

Issued at 913 PM MST Sat Feb 28 2026



04z surface analysis had high over ND/MN with stationary front 

from western MT to eastern CO. Some leftover low clouds over far 

northwestern SD per nighttime microphysics RGB. Water vapour loop 

showed westerly split flow over the CONUS, which will be the 

weather story through next week.



Split westerly flow is expected through next week with a series 

of weak disturbances pushing the aforementioned stationary front 

back and forth as warm fronts/cold fronts - perhaps with gusty 

winds at times. Limited Pacific moisture is foreseen with chances 

for light QPF across the south Monday and then most areas Thursday

through next weekend. However, the vast majority of hours will be

dry. The chance of >0.10" QPF during any 24-hour period is less 

than 30% on the plains and 30-50% for the Black Hills.
