600 FXUS63 KFGF 021920 AFDFGF Area Forecast Discussion National Weather Service Grand Forks ND 220 PM CDT Fri Oct 2 2026 .KEY MESSAGES... - Other than a few light rain showers tonight into Saturday, mostly dry conditions and near to slightly above average temperatures through the next seven days. && .DISCUSSION... Issued at 219 PM CDT Fri Oct 2 2026 ...Synopsis... West to northwest flow aloft with one weak shortwave entering northwestern ND and another, stronger wave further upstream over the Northern Rockies. That stronger shortwave will move out into the Plains on Saturday, pushing a surface trough axis into the Red River Valley. That shortwave moves quickly off to the Great Lakes, leaving northwesterly flow and surface high pressure for the later part of the weekend. West to northwesterly flow aloft continues into the upcoming work week. Some weak embedded shortwaves are not completely out of the question, but overall the pattern seems to be drying out as we head into the first full week of October. Some of the ensemble members are pretty amplified with upper ridging setting up over or just west of the Plains, but overall ECMWF EFI shows temperature signals just slightly on the warm side of average towards the middle and end of next week. ...Light rain tonight/tomorrow then dry and somewhat warmer... Most of the high resolution models bring two rounds of light rain, the first late this afternoon and tonight with the warm air advection and weak lead shortwave, and the second round with the stronger shortwave and surface trough axis. Regional radar and surface obs show some of the CAMs are already overdoing the first round, so not expecting much more than a few sprinkles at best. Better chances for some light rain later tonight into tomorrow. Probabilities of at least some measurable precipitation are high along and north of Highway 200, and there is even some 30 to 40 percent chances of seeing more than a quarter of an inch in northwestern MN. Probabilities for measurable rain drop off quite a bit after tomorrow. There is over 70 percent probability of 36 degrees or less in portions of our northern counties as well as our cold spots Monday morning. However, warming trend after that with temps returning to slightly above average values. There is even some low (20 percent) chances for far southeastern ND to see 80 degrees, although that looks like a bit of an outlier. && .AVIATION /18Z TAFS THROUGH 18Z SATURDAY/... Issued at 1237 PM CDT Fri Oct 2 2026 VFR conditions expected throughout the period as clear skies give way to some mid and high clouds. Some showers moving through late this afternoon and evening and again on Saturday, but not confident enough except at KDVL to include in the TAFs at this point. Winds that are light and variable at some locations will steady out of the south to southeast tonight, then pick up with some gusts close to 20 kts tomorrow morning. Some shift to the southwest and west starting at the tail end of the period. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...None. MN...None. && $$ DISCUSSION...JR AVIATION...JR
