576 FXUS63 KFGF 291139 AFDFGF Area Forecast Discussion National Weather Service Grand Forks ND 639 AM CDT Wed Apr 29 2026 .KEY MESSAGES... - Low chance for fire weather impacts Friday into this weekend. && .UPDATE... Issued at 636 AM CDT Wed Apr 29 2026 No changes were made to the forecast grids overnight. Overall with upper trough in Manitoba into E ND today with short wave energy in the trough moving thru a good deal of cloud cover anticipated for most. Cool today... a good 10-15 degrees below average for highs today. A region of mid level altocu and radar returns show a few pockets where some precip may reach the surface as it moves quickly southeast from DVL toward Fargo/Hillsboro next 1-3 hours. A few snowflakes in Tolna and Finley. But is is rather isolated and quickly moving so just left it cloudy and dry in the grids. && .DISCUSSION... Issued at 1252 PM CDT Tue Apr 28 2026 ...Synopsis... Surface analysis this afternoon shows a surface low working its way away from our area, diminishing the pressure gradient and thus allowing for winds to diminish. Afternoon cumulus has developed but will remain benign as dewpoints remain fairly dry. This will diminish after sunset with winds becoming more light and variable. The remainder of the week will be mostly rinse and repeat with temperatures in the 40s and 50s with generally light winds and dry conditions. Temperatures look to increase this weekend, which should cause relative humidity values to become lower. However, there is no strong signal for wind and green up is ongoing, so the probability for critical fire conditions is low. Having said that, near critical fire weather conditions may arise with minimum RH values around 20%, even without wind. Regardless, this remains the only weather impact for the forecast period. && .AVIATION /12Z TAFS THROUGH 12Z THURSDAY/... Issued at 636 AM CDT Wed Apr 29 2026 Considerable moisture in the 850-700 mb layer today into tonight....in that 5000 ft to 10k ft agl range.
