NWS Grand Forks, ND wrote its last area forecast discussion before the first event at Oct 31, 9:47 PM CST, 2 hours 13 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Grand Forks ND 1047 PM CDT Thu Oct 31 2024 .KEY MESSAGES... - There will be some light rain and even some snow passing through the area Friday, although only around a 10 percent chance for any accumulation on the grass and minimal impacts. - Additional chances for rain Sunday and Monday, with a 40 percent chance for thunderstorms. && .UPDATE... Issued at 1047 PM CDT Thu Oct 31 2024 Wind speeds remain light and variable across the FA with variable amounts of cloud cover as well. The clouds that were expanding from Roseau to Fosston to Cooperstown earlier have now thinned out quite a bit. The least amount of cloud cover currently extends along the Canadian border and down around the South Dakota border. There was some patchy fog at Langdon and Cavalier just after sunset, but it has since improved again. Therefore a quiet night is still in order. UPDATE Issued at 611 PM CDT Thu Oct 31 2024 Any light snow has remained east of this FA today and no precipitation is expected tonight. With wind speeds either light or becoming light, the only question will be how much cloud cover lingers and its effect on overnight lows. Most of the FA remains cloudy, but there are some holes or thin spots scattered about. It also seems like the clouds are expanding in coverage from Winnipeg to Roseau to Fosston then westward toward Cooperstown. The more clouds that linger will help to hold up temperatures overnight. && .DISCUSSION... Issued at 312 PM CDT Thu Oct 31 2024 ...Synopsis... Cut off low bringing snow to central and eastern MN will pull further off into the Great Lakes tonight, with surface high pressure building into the Eastern Plains. Another shortwave lifting into the region Friday afternoon and evening will bring a quick shot of light precipitation before ridging on Saturday. South to southwesterly flow on Sunday before a trough moves out Monday, then a bit of a break with northwesterly flow becoming more split flow by the end of the period. ...Light rain or snow tomorrow... The quick moving shortwave will bring a chance for some light rain or even light snow Friday afternoon as it approaches eastern ND. Model soundings are fairly dry, so we will lose some to evaporation but that will also help with cooling the layer. Best chances for seeing some flakes are from the Devils Lake basin south towards Valley City. However, probabilities of a tenth of an inch are less than 10 percent, and that will only be on grassy areas given that the precip will be falling in the afternoon. Rates are not expected to be high enough to overcome surface heating, and impacts are not anticipated. ...Precipitation Sunday into Monday... Much more amplified trough moving into the region for the end of the weekend and into Monday, with southeasterly surface winds expected to bring some moisture up into the region. Some of the ensemble members bring MU CAPE values up in the 500-1000 J/kg range into our southern counties, and the ECMWF extreme forecast index has CAPE up around 60-80th percentile of climo, so not completely out of the question. NBM prob thunder is around 20 percent mainly in our southern counties, and this seems reasonable. Regardless of thunder, decent precipitation amounts seem possible as NBM shows a 20 to 50 percent chance of a least an inch over 48 hours by Monday morning. && .AVIATION /06Z TAFS THROUGH 06Z SATURDAY/... Issued at 1047 PM CDT Thu Oct 31 2024 Have generally stuck with the timing and main ideas from the 00z set of TAFs. Light and variable winds overnight will become southeast on Friday, and remain in the 5 to 15 knot range. Cloud heights will lower Friday afternoon and evening, with guidance now indicating patchy MVFR conditions. Otherwise, it appears the best shower chances will still be at KFAR and KBJI. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...None. MN...None. && UPDATE...Godon DISCUSSION...JR AVIATION...Godon
