Area Forecast Discussion National Weather Service Grand Forks ND 706 AM CDT Tue Jun 14 2022 .UPDATE... Issued at 647 AM CDT Tue Jun 14 2022 Line of elevated convection continues to push across eastern ND this morning. An impressive radar depiction continues just west of the Mayville WSR-88D with increasing radar returns into MN in the last hour. Reports of severe winds reaching the surface over the past hour hard to come as storms are elevated. Still expecting pockets of wind to be reaching the sfc given that velocity shows 60+kts with rear inflow jet signatures. This activity will continue to quickly push north this morning clearing the area by 10am. && .SHORT TERM...(Today through Wednesday) Issued at 330 AM CDT Tue Jun 14 2022 Impacts today will be related to thunderstorms along and west of the valley. Upper low over northern MT and sfc trough extending across central ND with instability axis out ahead of strong convection in SD extending north into the SE ND will set the stage for an active morning. CAMs and environmental conditions suggesting that the area of convection in SD will continue to lift NE into eastern ND this morning fed by an axis of 3000 to 4000 j/kg of ML CAPE and 50 to 60 kts of 0 to 6km bulk shear. These storms are currently producing large hail up to 2 inches and winds of 70mph and little weakening is expected over the next few hours with an arrival time around 6am in SE ND. This activity will continue to lift north across eastern ND this morning with a broad sfc low and some weakening as it lifts into northeast ND with less instability and weaker mid level lapse rates. Nonetheless excessive rainfall, hail up to 1.5 inches and winds to 70mph will be possible this morning. Behind the low westerly winds will develop and bring drier air into the area with gusts this afternoon from the west at 35mph. The breezy conditions will diminish some overnight but redevelop tomorrow with gusts to 45mph in eastern ND. Cooler temps with mostly dry conditions tomorrow with slight chances along the northern border late tomorrow afternoon as the upper low approaches. .LONG TERM...(Wednesday night through Monday) Issued at 330 AM CDT Tue Jun 14 2022 Impacts in the extended time frame will be shower activity along the international border Wednesday night and Thursday then heat for the weekend. Cyclonic flow around departing upper low will bring the chance for showers across areas north of Hwy 2 Wednesday night and through the day Thursday gradually ending from west to east. Westerly winds will be lighter than Wednesday but still gusty in the afternoon with speeds up to 40mph in eastern ND. In the wake of the low a drier and cooler airmass will bring a temporary reprieve to the heat and humidity with highs in the 70s. Thursday night into Friday begins the warm spell with good model agreement in a significant ridge building into southern Canada with its thermal axis swinging across the northern plains on Sunday. Temps Friday will be in the 80s rising into the 90s for Saturday and some 100s entering the forecast on Sunday in the valley reaching as far north as the Grafton and Grand Forks. These would be record values Sunday as the record in Grand Forks is 95 and 101 in Fargo. Cooler Monday with a slight thunderstorm chance as southwesterly flow noses into the region with the ridge deamplifying some and shifting east. && .AVIATION...(For the 12Z TAFS through 12Z Wednesday morning) Issued at 647 AM CDT Tue Jun 14 2022 Line of storms pushing through the area this morning with east winds and MVFR stratus. Will see stratus lift late this morning and then winds turn to the west with gusts this afternoon up to 30kts. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...None. MN...None.
