Light showers falling into dry and very warm air resulted in several heat bursts at several locations west and northwest of Mobridge including Mahto, McLaughlin, Trail City, and to the south of Bullhead. All locations recorded sudden increases in temperatures and decreases in humidity along with spikes in wind gusts.

The episode as NWS ABR wrote it up.
Light showers falling into dry and very warm air resulted in several heat bursts at several locations west and northwest of Mobridge including Mahto, McLaughlin, Trail City, and to the south of Bullhead. All locations recorded sudden increases in temperatures and decreases in humidity along with spikes in wind gusts. The Mahto station rose 14 degrees in 20 minutes peaking at 96 degrees with a gust to 62 mph. At Mclaughlin, the temperature rose to 95 degrees with a 49 mph wind gust and a relative humidity of 18 percent. Although the wind only gusted to 30 mph at Trail City, the temperature still rose to 92 degrees with a relative humidity of 19 percent.

Area Forecast Discussion...UPDATED National Weather Service Aberdeen SD 926 PM CDT FRI JUN 24 2016 .UPDATE... Issued at 913 PM CDT FRI JUN 24 2016 The weather remains quiet this evening, which given the amount of shear and instability around, is good for this cwa. Capping warm mid-level temperatures in place is keeping clouds/storms from forming and keeping much of the convection off to the west and south from strengthening as it tries to move into central/south central South Dakota. Triple digit heat earlier this afternoon combined with dewpoints in the upper 60s to lower 70s was pushing heat index values up to 100F to 105F. Conditions have cooled down, though. KPIR is all the way down to 92 degrees here at 9PM. With surface dewpoints currently in the 60s to lower 70s across much of the cwa, should prove to be a warm night tonight with a cold front still analyzed back over far western North Dakota down into southeast Montana. Current forecast appears to be on track. No changes planned at this time. UPDATE Issued at 606 PM CDT FRI JUN 24 2016 See below for an updated aviation forecast discussion. && .SHORT TERM...(This Evening through Sunday Night) Issued at 317 PM CDT FRI JUN 24 2016 Temperatures have risen into the upper 80s and 90s this afternoon...with heat indices over 100 degrees across the far southwest. Will keep the current heat advisory in place through the early evening hours. A low pressure system and associated frontal boundary will track across the CWA late tonight and Saturday morning. Warm air aloft will likely hinder the potential for thunderstorms this afternoon and evening. There is quite a bit of instability around however...so should anything be able to develop...it could have enough strength to produce some hail. The western CWA would be the most likely area for any potential...where SPC has placed a marginal risk area. Instability diminishes and the best deep layer shear will be well behind the front on Saturday...so will keep pops fairly low. Other concern for late tonight into Saturday morning is winds across the west behind the front. Better potential for advisory winds looks to stay a bit west of the CWA...so will not issue any headlines at this time. The remainder of the short term period will be dry...with a return to closer to normal temperatures. Some concerns for fire danger across the west Saturday afternoon with relative humidities falling into the 20 to 25 percent range west river and with the expected gusty winds. However...fuels status page indicates that grasses are curing but not yet ripe for large fire growth...so will not issue any fire danger headlines at this time. High temperatures will be mainly in the upper 70s to mid 80s Saturday and Sunday. After a warm night with lows in the 60s to lower 70s tonight...will see lows mainly in the 50s Saturday night and Sunday night. .LONG TERM...(Monday through Friday) Issued at 317 PM CDT FRI JUN 24 2016 Decent agreement exists through the extended period. The main points of interest will be the rebuilding of the upper ridge, albeit to a lesser extent compared to previous occurrences this spring, over the Desert Southwest/Southern Rockies. There is only really one wave that is expected to traverse the ridge, entering the northern plains and dipping southeast. The right entrance region of a 70kt upper jet/Q vector bullseye suggests some upper support for convection. At current, the set up is for mid level warm advection to help support mainly nocturnal convection late Tuesday/early Wednesday. As typical with northwest flow waves, there is some concern about how long a period of moisture return can be expected before the wave arrives. Guidance brings surface dewpoints back into the low 60s for some modest MUCAPE, on the order of 1-2000 j/kg. With the exception to the passage of this wave, there is little major change in the surface pressure pattern and thus a lack of strong warm or cold advection. Temperatures this period should be close to climo. && .AVIATION...(For the 00Z TAFS through 00Z Saturday Evening) Issued at 606 PM CDT FRI JUN 24 2016 VFR conditions expected for all terminals. Southerly winds continue overnight and with a low level jet overhead expect wind shear conditions, especially at the KABR and KATY terminals. The threat of storms developing remains low for terminals overnight/early Saturday as a front, which will shift winds to the northwest, moves across the area. && .ABR Watches/Warnings/Advisories...
