AREA FORECAST DISCUSSION National Weather Service Sioux Falls SD 1247 AM CDT Tue Jun 21 2022 .SHORT TERM...(This Evening through Tuesday) Issued at 313 PM CDT Mon Jun 20 2022 Last day of the heatwave continues, with 19z temperatures in the 90s for most of the area. Dew points in the mid/upper 60s to lower 70s are creating heat indices of over 100 for most. Breezy southerly to westerly winds gusting up to 40 mph may help though, although the breezy is pretty toasty. Cold front across western Dakota continues to move east through the evening and tonight, trailed by a mid level wave (currently across eastern WY/CO and western SD/NE). Convection is already firing across the NE panhandle, and this area will be what to watch through tonight for the greatest severe threat. In this area through tonight, 0-6 km bulk shear values nearly parallel to the cold front above 40 kts is supportive of quick upscale growth. MUCAPE at or above 2500 J/kg provides plenty of instability near and just behind the front. All modes of severe weather are possible. Winds to 70+ mph are possible, given soundings continuing to show inverted V soundings, and DCAPE values over 1000 J/kg. Hail to the size of ping- pong balls is possible with mid level lapse rates over 7.5 deg C/km. Can't rule out a tornado, with strong 0-1 km shear. Again, the greatest risk remains from northeastern SD to southwestern SD, just clipping the northwestern portions of our CWA (from Huron to Chamberlain, SD). However, this could change or shift slightly to the east if line motion becomes more easterly than anticipated (i.e. follows closer to the cold front motion than the mid level wave motion). This risk would be greatest from 7PM (00z) to midnight (05z). Additionally, there appears to be a subtle dryline across the James River and extending south into central NE, where winds has been a bit more westerly and dew points are a touch lower. Will need to watch new development in central NE, likely diurnally driven near the dryline. If this can maintain itself, could see storms, possibly severe, across the MO River Valley moving into southwestern MN ahead of the main show. Expect wind gusts to 70 mph to be the main threat with any of this development, although hail to half dollar size is possible (less likely given the less steep mid level lapse rates and bulk shear around 25 kts). This risk would be highest from 5PM (22z) to 9PM (02z). To summarize this evening/tonight's convection: greatest severe risk remains to the north and west of our coverage area, but isolated to possibly scattered severe storms are possible, with the greatest risk from Huron to Chamberlain, SD. Isolated to scattered storms possible elsewhere, with some severe risk. Folks with outdoor plans should remain weather aware this evening through the early overnight, with multiple ways to receive warnings. Temperatures remain quite warm tonight, with lows in the 60s to mid 70s (coolest in the west behind the front). Slightly cooler tomorrow, with highs in 80s to lower 90s. Behind the front on Tuesday, northwesterly surface winds remain on the breezy side. .LONG TERM...(Tuesday Night through Monday) Issued at 313 PM CDT Mon Jun 20 2022 For mid week, dome of high pressure returns, with mid level flow becoming more zonal. Warming trend through mid week, with lower level flow beginning to shift more southerly and much warmer temperatures build in to the west ahead of the next wave rotating through the top of the ridge. Chances for thunderstorms return for Thursday and Thursday night, with another wave Friday afternoon/evening. With models disagreeing on timing and strength of the waves, difficult to say if/when/where any severe weather threat would be. That said, this period may be one to watch for possibly stronger storms as heat and humidity build in, and may coincide with increased forcing. Slightly cooler, but near seasonal temperatures return for next weekend and into early next week. Although again varying on the strength and timing, deterministic guidance shows a more robust mid/upper trough moving through next weekend through early next week. Expect continued shower/storm chances, but too much uncertainty in timing given model differences to stray from the blend. && .AVIATION...(For the 06Z TAFS through 06Z Tuesday night) Issued at 1244 AM CDT Tue Jun 21 2022 VFR conditions are expected for the TAF period. A cold front is currently pushing through the region, bringing showers and storms with it. Should see showers and storms continue through the first few hours of the TAF period, mainly along and east of I-29. This includes KFSD and KSUX. Aside from rain chances, low level wind shear will begin the period at KSUX due to the low level jet but should drop off after the cold front pushes through by 08Z. West/northwest flow takes over behind the front, with gusts increasing into the 20-30 knot range for the afternoon hours today. Should see gusts drop off around sunset as mixing ceases and an inversion strengthens. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...NONE. MN...NONE. IA...NONE.
