Area forecast discussion, May 7, 11:22 PM CDT, 3 hours 58 minutes before
Area Forecast Discussion National Weather Service Grand Forks ND 1122 PM CDT Thu May 7 2026 .KEY MESSAGES... - At least near critical fire weather conditions will continue through the weekend with a 20 percent chance for critical fire weather conditions on Friday. && .DISCUSSION... Issued at 221 PM CDT Thu May 7 2026 ...Synopsis... Northwesterly flow aloft continues through tonight and tomorrow, with the next shortwave digging down Friday night into Saturday. The northwesterly flow aloft returns for Sunday and Monday before another shortwave pushes through the Northern Plains Monday night and Tuesday. After this shortwave, ensemble members are all over the place with some clusters pushing ridging into the Plains and other clusters keeping us in northwesterly flow. Predictability is low although the ECMWF EFI does show our colder temperatures signal transitioning over to warmer than average by days 6 and 7. ...This afternoon's near critical fire weather... Temperatures finally not quite as cool as they have been this week and most spots have risen into the 50s. With dew points in the teens to low 20s, relative humidity values have dropped into the 20 to 30 percent range for the most part. Winds are mostly under 15 mph although a few spots are gusting up to around 20 mph. SPS for near critical fire weather conditions continues to seem good, and the low RH values will continue into this evening before temperatures start to drop. ...Tomorrow and beyond fire weather concerns... Similar RH values are expected for tomorrow afternoon, and there will be more of a pressure gradient as a surface trough moves through. While winds look higher than today, there is only around 30 kts to mix down and not much in the way of pressure rises. The 50th percentile of NBM has some 25 mph sustained winds in east central ND, but may be due to the NBM's bias in that area. The HREF joint probability for winds over 25 mph and RH values under 25 percent doesn't have much. Dropping the winds threshold down to 20 mph gives us some low chances for critical fire weather conditions on the MN side, around 20 percent. Definitely could see critical to near critical fire conditions for tomorrow afternoon, but not confident enough to go with a watch at this point. Still breezy into Saturday, but slightly cooler temps should bring higher RH values and there will be a low chance for showers. Less wind and similar RH values for Sunday. && .AVIATION /06Z TAFS THROUGH 06Z SATURDAY/... Issued at 1119 PM CDT Thu May 7 2026 VFR conditions will prevail for the TAF period. Winds will remain light and variable overnight, becoming northwesterly to northerly through the day tomorrow. Winds will peak early to mid afternoon with sustained winds in non-tree landscapes generally 15-20 knots, gusting to 30 knots, with more tree filled areas generally 10-15 knots, gusting to 20 knots. Showers will move through late tomorrow afternoon, potentially impacting TAF sites, although rainfall rates should be light enough to avoid any visibility reductions. The main concern from any showers will be changes in wind direction and speed beneath these showers as we remain fairly dry near the surface. These will work their way southeastward and exit the region after the TAF period ends around 09-12z Saturday morning. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...None. MN...None. && DISCUSSION...JR AVIATION...Perroux
