Area Forecast Discussion National Weather Service Grand Forks ND 1154 PM CDT Sat May 7 2022 .UPDATE... Issued at 1150 PM CDT Sat May 7 2022 Rain area is moving out of ND and into MN at 05z. On backedge of rain there has been sporadic wind gusts, mostly in the 45-50 mph range, but isolated brief wind gusts 58 mph at KRDR and a few other reports. Did SPS for isolated wind gusts 50+ mph thru the RRV and into parts of NW MN in area area to cover this. No thunderstorms associated. UPDATE Issued at 1024 PM CDT Sat May 7 2022 Area of convection that was in South Dakota, was for a time severe around Aberdeen, is moving into SE ND and much weaker. Some lightning remains though but radar shows rates of rainfall are manageable so far but will need to be monitored. Expanded area of rain to Grand Forks as well light to moderate but rates are manageable too and not expected to cause issues. Grids had pops and weather handled well so only minor tweeks needed. Let the wind adv expire at 03z. UPDATE Issued at 703 PM CDT Sat May 7 2022 Feel uncertain in how tonight will play out. Main short wave energy is lifting into western Manitoba and strongest convection of the afternoon/early evening has been tied to this short wave. Storms with this from Bottineau north. The overnight precipitation seems to be tied to a second wave in South Dakota with thunderstorms increasing in coverage near the Missouri River west of Aberdeen southward. Short term models do hint at this cluster moving northeast and into the southern valley overnight and the focus for heavier rain in the south valley. That area can take more rain. Question is the north as they can take little additional rain without issues. Right now that area seems to be on a lower chance for heavier rain overnight. Mid level showers moving into E ND creating pockets of wind gusts over 40 kts Carrington ND area and feel better extending wind advisory to 03z. && .SHORT TERM...(This evening through Sunday night) Issued at 332 PM CDT Sat May 7 2022 Strong winds continue this afternoon within the Red River Valley and a Wind Advisory remains in effect through 7 PM. Gusts 45 to near 50 mph have been reported so far, and this is still on track to linger through the peak heating period as a strong LLJ remain in place. We continue to focus on potential for increasing rain and possible thunderstorm chances late this afternoon through Sunday, with a window for severe thunderstorms still possible from late this afternoon into the early evening hours. Due to widespread cloud cover a strong cap has remained in place across our west, and confidence in initiation this far east is lower and we will continue to have to watch upstream trends for stronger updraft development. There are a few elevated showers that have developed along the axis of WAA and LLJ, but while elevated instability has increase to near 1000 J/KG so far there are no indications near our CWA more than lighter shower activity. This will chance as more organized forcing increases and coverage overspreads our CWA later this evening. The window for organized cells to the west holding together will be dependent on timing before CAPE begins to decrease. HREF shows mean MUCAPE quickly dropping off in our west between 00-02Z, so that would close the window on potential for severe updrafts despite stronger effective hear 35-55kt lingering. Due to recent trends it appears most likely scenario will be elevated cores with hail to 1.5" (dependent on timing) through 8PM in our west quickly transitioning to more of a moderate to heavy rain threat through the rest of the evening/overnight. CAPE profiles (skinny) and high moisture advection (PWATs increasing to as high as 1.4") would support efficient rainfall where clusters form, however there is not a signal for 1"/hr rates from HREF/NBM that would be indicative of localized convective/higher totals. The southern RRV should be able to handle a prolonged 1" rainfall easier than the northern valley before more than minor overland type flooding becomes an issue. NBM probs still favor 0.5-1" likelihood from this evening into Sunday morning with higher probs for 1"+ in the southern RRV. A "lull" in shower coverage/intensity arrives. Then the next wave (possibly stronger) begins to move back into the region Sunday night and the rain signal increases once again and with that wave probs for 1"+ shift further north and may begin to favor these higher towards toward locations where overland flooding has been a persistent issue. .LONG TERM...(Monday through Saturday) Issued at 332 PM CDT Sat May 7 2022 An active and unsettled pattern prevails this upcoming week. A series of impulses will transition through southwest flow aloft bringing several chances for precipitation through the period. For Monday, ongoing showers and thunderstorms continue working to the northeast as the surface low transits into southern Manitoba and Ontario. The potential for heavy rain remains high as abundant moisture and instability remain in place. Expecting locally heavier rain with embedded thunderstorms; however, overall there is the potential of up to two inches of rain, mainly in the vicinity of the Red River valley. Showers will gradually come to an end in the early morning hours of Tuesday, with high pressure bringing quieter weather to the region. The upper ridge amplifies across the upper Mississippi valley and Great Lakes region resulting in mostly clear skies and temperatures rebounding across the area on Wednesday. By Thursday...a vigorous short wave digs into the base of the trof in the Four Corners region. As the wave digs, it induces stronger cyclogenesis and a dynamic system develops with an attendant cold front. As the system matures, showers and storms will overspread the region. Abundant moisture is available to wrap into the system as it rides north with a 40 to 50 knot jet helping to trigger convection. Otherwise, expect a slower transit of the system as the upper trof becomes more negatively tilted, prolonging rainfall over the area. The system finally lifts north and exits the area by late Friday bringing surface high pressure to the area, and more tranquil weather to end the period. && .AVIATION...(For the 06Z TAFS through 06Z Sunday night) Issued at 1150 PM CDT Sat May 7 2022 Sproadic wind gusts will continue in the RRV into parts of NW MN overnight, so wind speeds look for be variable through 08z. Overall though they will remain SSE in the RRV and MN into Sunday while DVL area should see a wind shift to a more southwest or even west direction for a time behind a weak trough. This trough likely to wash out before it reaches much past DVL Sunday morning. HRRR continues to show development of lower end MVFR clouds toward morning in the RRV and into MN so kept this idea. Though as usual how low and timing of development is uncertain. MVFR cloud deck looks to persist through Sunday, even risk of IFR cloud deck developing higher terrain areas such as BJI. DVL looks to remain VFR into Sunday. && .HYDROLOGY... Issued at 123 PM CDT Sat May 7 2022 Ongoing significant flooding will continue through the remainder of the weekend for many locations. Overland flooding continues in parts of the northern Red River valley with backwater issues from the mainstem Red and tributaries. Four areal flood warnings remain in effect and there remain areas in northeast North Dakota where several roads remain closed due to being washed out from flood waters. Temperatures will continue their warming trend this weekend. The overall weather pattern will become more active beginning this evening and continuing through the weekend, and again late next week. Red River mainstem... All points on the central and southern Red have crested. The greatest high impact flooding along the mainstem Red continues to be near Grand Forks (moderate flooding) with major flooding ongoing downstream to the Canadian border. Oslo and Drayton have crested but remain at major flood stage while Pembina is near crest and should remain near crest for the next several days after that. Minnesota tributaries... All points along the Minnesota tributaries continue to recede, with levels continuing to lower over the next several days. However, uncertainty remains with how future precipitation late this weekend may impact the rivers at this time. North Dakota tributaries... The main action along the North Dakota tributaries continues to be along the Sheyenne and Pembina Rivers. A re-rise to flood stage at several locations is likely with adjusted releases from Baldhill Dam. Downstream, Lisbon is forecast to dip slightly below flood stage before rising again to minor flood stage. Kindred is forecast to remain in major flood stage for the next few days before receding. West Fargo is at moderate flood stage but another crest above major flood stage is anticipated as upstream flows reach this forecast point. Harwood remains at moderate flood stage and will see a second crest at moderate as the wave crest works its way downstream toward the mainstem Red. The re-rise in the Mapleton forecast puts the crest at minor flood stage as a result of the added flow making it to that point. Major flooding continues on the Pembina River at Neche, along with plenty of overland flooding and high river levels on smaller rivers and streams across far northeastern North Dakota. Neche has appeared to crest and is forecast to slowly fall over the next several days. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...None. MN...None.
