800 FXUS63 KABR 150204 AAB AFDABR Area Forecast Discussion...UPDATED National Weather Service Aberdeen SD 804 PM CST Fri Nov 14 2025 .KEY MESSAGES... - Cooler temperatures in the 40s and 50s this weekend, cooling even more into the 30s and 40s early next week. - Rain/snow chances (30-50%) return Monday/Monday night, but many uncertainties in regards to system strength and overall precipitation placement/amounts. && .UPDATE... Issued at 753 PM CST Fri Nov 14 2025 Currently, got a cold front working southeast through the region. There is some strong mid-level (700-500hpa) forcing coupled with a 110-130+knot upper level (300-200hpa) jet streak over western/central North Dakota extending down into western South Dakota, as well. The net result is light to moderate banded rain extending from northwest South Dakota up into central North Dakota. During the next 12 hours, these features will shift east toward the border of Minnesota and the Dakotas. Eventually, PoPs may have to be extended further south across the CWA. Measurable precipitation (0.01in or greater) still appears feasible mainly across the northern tier counties of north central and northeast South Dakota/west central Minnesota. No changes planned to overnight temperatures right now. Monitoring for the potential need to drag small measurable PoPs southward across the CWA for the overnight hours. UPDATE Issued at 543 PM CST Fri Nov 14 2025 See below for an aviation forecast discussion for the 00Z TAFs. && .DISCUSSION... Issued at 135 PM CST Fri Nov 14 2025 Temps have warmed well into the 70s across the far southwest CWA, with winds gusting around 25 mph close to the White River. Will be monitoring potential for Red Flag issuance this afternoon, but will see if critical conditions expand much further north through Lyman/Jones counties. If it stays rather localized to far southern portions of that area, will likely refrain from headlines. RH down that way ranging between 20 and 25 percent with readings likely to drop a bit lower through the rest of the afternoon. No changes to the rain chances (20-40%) across the northern CWA tonight as the frontal boundary moves south through the area. Any rainfall though will be very light and likely be less than a tenth. Will be fighting dry air initially and will likely take until after 06Z for better saturation to develop. With the Monday system, there`s still some uncertainty in regards to the path of what now appears to be a potential closed 500mb low moving east-northeast across the central/northern plains. Precip placement still varies, but overall the ENS/GEFS show 24-hr mean precip totals to be less than 0.25in. 90th percentile 24-hr QPF is on the order of 0.25in - 0.40in. && .AVIATION /00Z TAFS THROUGH 00Z SUNDAY/... Issued at 543 PM CST Fri Nov 14 2025 Terminals KABR,KATY,KPIR,KMBG VFR conditions are forecast through the TAF period. Will watch the guidance/satellite/obs for low probability of a band of MVFR CIGs developing/moving into the forecast area Saturday morning behind a passing cold front. Confidence on areal coverage is low, but will take a deeper dive into the potential for the 06Z TAFs. Sticking with the potential for a period of low-level wind shear (LLWS) tonight in association with a cold frontal passage. Already seeing two different bands of light to moderate rain falling over western North Dakota. There may be enough post-frontal banded-type forcing across northern SD later tonight to produce some of this light to moderate rain over the KMBG and KABR terminals. PROB30`s have been introduced for this potential. && .ABR WATCHES/WARNINGS/ADVISORIES... SD...None. MN...None. && $$ UPDATE...10 DISCUSSION...TMT AVIATION...10
