NWS Grand Forks, ND wrote its last area forecast discussion before the first event at Jun 9, 2:02 PM CST, 1 hour 13 minutes earlier.
Area Forecast Discussion National Weather Service Grand Forks ND 302 PM CDT Fri Jun 9 2023 .SHORT TERM...(This evening through Saturday night) Issued at 302 PM CDT Fri Jun 9 2023 Convection and smoke will be the main issues for the period. Northwesterly flow aloft with a reinforcing shortwave digging down this afternoon and tonight. This will help push the cold front currently near the international border down through the CWA during the night. There is a good amount of ML CAPE of around 2000 J/kg near the boundary, and effective bulk shear is around 30 kts. A few storms that have crossed into ND have been pulsing up and producing winds just under severe criteria around 50 mph. There will continue to be a few strong to severe cells as the frontal boundary pushes south this evening. HREF has a few paintballs with updraft helicity over 75, but not a lot and at this point it seems probability of severe will be around 10 percent. By 04 to 05Z, even the more bullish CAMs have convection diminishing down to showers and pushing southward out of our CWA. Have some low POPs lingering in our south a bit longer for some post-frontal shower activity, but otherwise should start to become more quiet on the precipitation side of things as we head through tonight and into tomorrow. With a large amount of Canadian wildfires upstream of both upper flow and surface winds, seeing some smoke will be a possibility late tonight into tomorrow. The HRRR and RAP both have some high vertically integrated smoke coming into our northern counties this evening, so continued the trend of including higher sky cover even with clearing behind the front. Surface smoke is more questionable, with Canadian and domestic models both showing only small concentrations of low level smoke. There will be good mixing behind the cold front, but not confident enough to include in the grids at this point. Saturday will be pretty quiet with cold air advection continuing. Northeast winds will get somewhat breezy with gusts up into the 25 to 30 mph range in eastern ND. However, temperatures will be quite a bit cooler than they have been recently, and the afternoon RH values should stay mostly above 30 percent. The only area where they could get close to 30 percent will be in our northeastern counties, where winds are expected to be lower. Thus, think fire danger will not be too much of an issue on Saturday. Conditions will be cool and quiet Saturday night with high pressure and temperatures dropping into the upper 40s in some areas. .LONG TERM...(Sunday through Friday) Issued at 302 PM CDT Fri Jun 9 2023 Sunday and Monday...Conditions remain fairly quiet with the main upper low lingering over the Great Lakes. Surface high pressure remains across the Plains, with relatively dry air coming down out of Canada. Remains to be seen if we get any high or surface level smoke from Canadian wildfires, as smoke models don't go out that far, but will keep an eye out. Temperatures will be close to seasonal averages on Sunday, but start to rise a bit on Monday as upper ridging builds in to our west. Tuesday through Friday...The upper ridge over the western Plains starts to break down a bit and move eastward. There is the potential for some ridge riding shortwaves to come down into our area, but much will depend on exact timing of the ridge breaking down and particulars of small scale features that cannot be resolved at this point. By Thursday, there is decent agreement on the main ridge axis moving into MN, with more of a trough building into the Northern Rockies and then into the Plains on Friday. Cluster analysis has an even split with the strength of the upper trough, with some holding the ridge in the central CONUS a bit stronger and other solutions showing fairly strong troughing in Manitoba/North Dakota. Precip chances should be increasing for the end of the week with the trough over us or approaching, but specifics hard to nail down. Temperatures will rise back above seasonal averages by mid-week. && .AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1249 PM CDT Fri Jun 9 2023 Scattered showers and thunderstorms ahead and along a cold front that will be dropping into the forecast area this afternoon and evening, so have VCTS at most airports. Think that most sites will remain VFR, but could see some brief reductions to visibility if a cell directly impacts the airport. Probabilities of this are not high enough to include even in a tempo group at this point. Behind the cold front, winds will shift to the north and northeast, although there will be some smoke getting mixed down to the surface. Could see some lowered vis around 3-5SM during the early morning hours after the frontal passage. Think smoke conditions should improve by later in the morning, so have VFR conditions returning after 12Z. Winds will be fairly breezy behind the front with gusts over 20 kts from the northeast. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...None. MN...None. && SHORT TERM...JR LONG TERM...JR AVIATION...JR
