.DISCUSSION...(This Evening Through Tuesday)
Issued at 1235 PM MST Tue Nov 3 2026

Upper level analysis shows upper trough axis centered from the
Upper Midwest through the Southern Plains. Further upstream, water
vapor imagery shows closed upper low moving onshore across northern
CA and OR/WA. Diffuse surface high pressure over the northern Rockies
into Northern Plains with brisk NW surface flow across the forecast
area. Lingering low clouds across south-central SD will erode this
afternoon with widespread sunshine today. Winds will diminish through
the day as the surface low pulls eastward. Western upper low is
forecast to eject into the Southern Plains Wednesday into Thursday,
although precipitation will remain east the area. Generally dry
weather will persist through the week with seasonable temperatures.
Dry clipper system will push through the Northern Plains Friday
into Saturday, although wind potential has diminished considerably
from previous model runs. Western ridge will build Sunday into
early next week. Temperatures are trending 5-15F warmer than
normal Sunday through Tuesday. Ensemble guidance keeps the area
dry through at least mid-week next week before more active western
flow returns by end of next week, although there are no major
precipitation signals thus far.
