Area Forecast Discussion National Weather Service Grand Forks ND 339 AM CDT Sun Jun 25 2023 .SHORT TERM...(Today through Monday) Issued at 338 AM CDT Sun Jun 25 2023 Additional rainfall amounts will be the main concerns for the period, along with how much near surface smoke our area gets from Canadian wildfires. Showers continue to rotate around the low pressure system into our CWA, although much of the lightning activity has ended as MU CAPE has dropped below 500 J/kg. Still seeing some locally heavy rain moving into portions of the northern Red River Valley, so will have to watch as a few spots in that area have already received over 4 inches. There has been a downward trend in radar returns further south and east, so let the flash flood warning convert to advisory for any lingering high water, but impacts should be decreasing. The CAMs have been consistent on rapidly diminishing showers through the overnight hours, a bit faster than has happened in reality. Think with cyclonic flow there will be some continued precipitation into the morning, but with elevated instability decreasing there should be mostly light rain lingering. The low will slowly pull off to the east during the day, and think that most of the precipitation will shift to east of the Red River by afternoon. There is some indication of elevated instability increasing again, but very little at the low levels and bulk shear is around 10 kts. Could see thunderstorm coverage increase again in our eastern tier this afternoon and evening, but at this point think that chances of a repeat of last evening are low. Probabilities of over half an inch of rain diminish rapidly as the day goes on, but some locally heavy rain and lightning are possible. HRRR and RAP models both have some near surface smoke progged across mainly our northern counties. With recent rain there hasn't been a lot of lowered visibility, although a few spots in northwestern MN have gone down to 5SM. Air quality alert continues for northwestern MN through today. The upper low will continue to pull off to the east tonight, with ridging building into the Plains on Monday. After a relatively cool start in the 50s there should be enough sunshine to bump temps into the 80s by afternoon. There are some model solutions bringing a ridge riding shortwave into our northern counties by Monday afternoon, so kept some POPs going near the international border. CAPE could get up to 1500 J/kg, but deep layer bulk shear is again very low at around 15 kts. Not expecting much in the way of severe impacts. .LONG TERM...(Monday night through Saturday) Issued at 338 AM CDT Sun Jun 25 2023 Monday night through Wednesday...Upper ridging over the Plains Monday night starts to break down and move east Tuesday into Wednesday as a shortwave trough comes in out of Canada/Northern Rockies. CAPE and deep layer bulk shear values that the deterministic models put out are not very impressive (around 1000 J/kg and 15 kts), but there is quite a bit of deviation in the ensemble spread, with up to 2000 J/kg put out by some members. Given the potential for summertime surprises, can't rule anything out and will continue to keep an eye on the mid-week system as the time period gets closer. Thursday through Saturday...Flow over the Northern Plains becomes more quasi-zonal and then northwesterly as an upper low digs down from Manitoba/Ontario into the Great Lakes. While the main upper support looks to be east of our area for the end of the week and into the weekend, there is still the potential for embedded shortwave and smaller scale features the ensemble members can't resolve. Overall, chances for thunderstorms and near average && .AVIATION...(For the 06Z TAFS through 06Z Sunday night) Issued at 1158 PM CDT Sat Jun 24 2023 Variable flight conditions continue across eastern ND and northwest MN as a result of a strong system bringing showers and thunderstorms that will continue to impacts most terminals through at least the morning hours Sunday. Along with the shower/storms there is some lingering smoke early in the TAF period adding to the vis reductions in northeast ND and parts of northwest MN (should scour out with shifting winds). MVFR to IFR ceilings are also expected, with VFR eventually returning west to east. It will take longer for conditions to improve Sunday in MN, and IFR may linger at KBJI. A period of gusty north winds eventually develops as this system transitions east Sunday, but winds should decrease as high pressure builds and the sun sets Sunday evening. && .FGF WATCHES/WARNINGS/ADVISORIES...
