812 FXUS63 KBIS 101201 AFDBIS Area Forecast Discussion National Weather Service Bismarck ND 600 AM CST Mon Nov 10 2025 .KEY MESSAGES... - Warming trend this workweek with no precipitation in the forecast until Friday night. - Breezy across most of the state today and Tuesday, and in the east on Wednesday. && .UPDATE... Issued at 600 AM CST Mon Nov 10 2025 These overcast high Chinook arch clouds will not end, and no model has them. So adjusted the cloud forecast accordingly. The James River Valley continues to have 1 to 3 mile visibilities with the fog. && .DISCUSSION... Issued at 200 AM CST Mon Nov 10 2025 Currently a large sits over the western CONUS, with a large trough and upper low in the Great Lakes Region. The ridge axis is over Montana and moving east. At the surface high pressure sits in the eastern half of the Northern Plains, with lowering pressure in Montana from a low in northern Alberta Canada. Low stratus has lowered in the James River Valley to create fog. Today the warming trend continues, pulling us away from that false winter we had over the weekend. With the ridge axis entering the state today, an axis of warmer 850mb temperatures comes with it. The west will see temps back in the 50s, while the east warms to the 30s. On the backside of the ridge axis, the flow flattens to zonal flow. This will then continue the warm up as east moving air over the Northern Rockies creates warming Chinook winds entering the state. Tuesday though the flow turns slightly northwest so expect slightly cooler temps. Then Wednesday to Friday another ridge moves in, warming most of the state back into the 50s and maybe even the 60s. Today through Wednesday will be breezy, but there is no need for an Advisory. Next weekend two low pressure systems looks to develop. One will be a cut-off low moving through New Mexico, and the other a low in southern Canada. So Friday night the flow turns southwest with a surface front moving through. This will bring a slight chance of rain (25%) to the region, although currently difficult to forecast. Those rain showers may ling through Saturday before another ridge looks to move through. && .AVIATION /12Z TAFS THROUGH 12Z TUESDAY/... Issued at 600 AM CST Mon Nov 10 2025 VFR through the period, except this morning. The east currently has LIFR CIGs with fog. This fog should end this morning. Winds will gust around 25kts from the south today. This evening and overnight WS is possible across all terminals. && .BIS WATCHES/WARNINGS/ADVISORIES...
