Area Forecast Discussion National Weather Service Grand Forks ND 1024 PM CDT Wed Jun 29 2022 .UPDATE... Issued at 1024 PM CDT Wed Jun 29 2022 Cold front appears to be just west of our CWA, with surface troughing still in place over our CWA and a Theta-E gradient along a stalled warm front in our south. The window is still there for severe potential mainly in our south along the stalled frontal zone. According to SPC objective analysis MU CAPE exceeds 3500 J/KG and DCAPE is still hovering around 2000 J/KG near ND/SD border where very steep mid level lapse rates are in place. The atmosphere remains strongly capped and this activity is likely to remain elevated as is moves into our CWA. As upstream clusters move east there is still enough shear for brief surges or linear features that could create greater wind impact potential. At this point damaging winds are the most likely threat, hail threat is probably on the marginal side, and tornado threat is minimized due to the elevated nature of convection (still can't be ruled out as 0-3km shear remains 30-35kt). Window still appears to be over the next several hours and after that any elevated clusters are likely to become less organized. UPDATE Issued at 706 PM CDT Wed Jun 29 2022 Strong cap in place locally and limited synoptic ascent has so far limited initiation and latest HRRR runs have reflected the delay in initiation and significant lowered confidence in severe potential further north. Instability/shear will still be in place, so I don't want to completely rule out activity further north but right now better potential is trending towards our south. Regarding our southern CWA: Upstream trends in SD show several organizing clusters within region of weakening CINh and a bit better synoptic ascent associated with an impulse within west- southwest flow moving out of WY. Ahead of this activity ML CAPE axis of 1500-2500 J/KG remains in place and is shown by RAP to linger in our southern CWA through the late evening before transitioning to a much more elevated layer and weakening. Mean winds and corfidi vectors both initially favor a west to east track, however after 03Z take on a northeast component as the cold front starts to arrive in the northwest and prefrontal troughing shifts. Last few HRRR runs support this upstream activity in SD eventually spreading into SE ND after 9Z (10PM) and into west central MN closer to 5-6Z (midnight). During the same period instability may be decreasing/becoming more elevated. Still, 0-3km and effective shear are adequate for sustained severe potential, though with lowered confidence in supercells and more elevated MCS tendencies trends may transition more towards wind/hail. How far north and how long that activity maintains it strength is a tough call at this point. Current Severe Thunderstorm Watch for our area in the south through 1AM is covering this threat for the later evening period. && .SHORT TERM...(This evening through Thursday night) Issued at 246 PM CDT Wed Jun 29 2022 Focus will be given to potentially impactful severe storms this evening. Hazards from strongest storms include chance for very large hail at least 2 inches, winds to 75 mph, and still cannot rule out a brief, isolated tornado. Moderate to strong instability is developing in the Dakotas given increasing low level moisture content and warming temps amidst clear skies. GOES WV and JPSS ALPW still show a stout EML advecting out of WY/MT into the Dakotas over the warming, moistening PBL contributing to strong instability. However this stout EML brings a capping inversion in which sufficient forcing will have to overcome. There is a mid level wave noted on GOES WV moving ENE across far northern MT into southern SK/MB, with attendant dryline followed by cold front still in MT. This wave is also contributing to ample shear across much ND. There is also a pre-frontal trough across western/central ND noted by northerly winds next to southerly within a similar thermodynamic air mass. While this prefrontal trough and perhaps eventual dryline could provide the foci need for initiation, better synoptic forcing aloft looks to miss the area staying in Canada, as well as the absence of better sfc convergence along a sfc boundary looks to favor the capping inversion to suppress sustained convection for discrete supercells as was once depicted by 12 Z guidance. However, we are still not discounting this conditional threat of discrete supercells into eastern ND just yet, but rather the probability appears to have decreased. Should robust convection initiate, isolated, discrete supercells capable of all hazards will be possible, some of which may be longer tracked if they can sustain themselves internally. Strongest storms will be capable of very large hail. In addition to the SK/MB shortwave trough, a second mid level impulse is moving ENE out of WY into SD/NE as noted on satellite imagery. This impulse is already developing clusters of elevated storms moving into SD, with a large unstable warm sector downstream across most of SD. There is some indication that these clusters will continue east, perhaps congealing into an MCS across SD this afternoon. With the warm sector extending into our southern CWA by early evening and mean wind vectors ENE, this activity could eventually spread into the southern CWA. With very steep lapse rates contributing to strong instability and ample shear available, this activity could be strong to severe later this evening. This appears to have a better chance to bring hazardous weather into the area compared to the aforementioned SK/MB trof and ND pre-frontal trough. While general multi- cell/quasi-linear mode is expected given preference for fast moving OFBs, elevated mesocyclones are possible. There is event some backing of winds with height aloft to perhaps favor anticyclonic mesocyclones which would tend to deviate storms north into ND out of SD as well as bring chance for large hail despite non-discrete mode. Lastly, strong DCAPE, steep lapse rates throughout the column, and linear mode may bring chance for winds over 75 mph, but confidence of this significant wind hazard into our area is low at the moment. Forcing with the WY/SD wave should move east of our area overnight tonight after 3 AM, and thus this is when thunderstorms should move out of the area. Otherwise, the aforementioned cold front eventually moves through the area Tuesday bringing clouds, milder temps, and breeze out of the northwest. .LONG TERM...(Friday through Wednesday) Issued at 246 PM CDT Wed Jun 29 2022 Friday through Sunday...Northwesterly flow aloft for the end of the week and into the holiday weekend. Several weak shortwaves will be moving through the northwesterly flow, so chances for showers and thunderstorms will continue periodically through Saturday and Sunday. Timing and placement of each shortwave is still a bit uncertain at this point, with no strong signals in the ensemble R and M climate for wetter than usual conditions. Temperatures on Friday will start out on the cooler side of seasonal averages but highs will warm back up into the 80s over the weekend. Monday through Wednesday...Upper heights will begin rising as ridging starts to build into the central CONUS. However, there will still be several weak shortwaves riding over the top of the ridge so thunderstorm chances will continue on and off through the holiday and into the middle of next week. Temps should remain close to seasonal averages. && .AVIATION...(For the 00Z TAFS through 00Z Thursday evening) Issued at 706 PM CDT Wed Jun 29 2022 VFR conditions should prevail across eastern ND and northwest MN, with main aviation impacts related to possible thunderstorm activity during the late evening/early morning period. Best chances based on current data are in southeast ND and west central MN, with lower chances further north. I reflected this trend with this TAF updates limiting mention to KFAR/KBJI (less confidence further north). How strong these showers/storms will be is also a question, but potential is there for severe winds/hail depending on how far north the stronger activity holds together. Winds shift to the northwest behind a cold front after 09-12Z, increasing through the daytime period Thursday (gusts 25-30kt likely). && .FGF WATCHES/WARNINGS/ADVISORIES... ND...None. MN...None.
