AREA FORECAST DISCUSSION National Weather Service Sioux Falls SD 1010 PM CST Wed Nov 30 2022 .SHORT TERM...(This Evening through Thursday Night) Issued at 246 PM CST Wed Nov 30 2022 KEY MESSAGES: 1) Gusty winds continue heading into the weekend, with the strongest gusts forecast to occur Friday through Saturday morning. Generally around 30 to 40 mph, with isolated gusts near 45 mph possible at times. 2) Warmer on Thursday and Friday with the aid of southerly flow. 3) Quick moving shortwave brings snow chances to those north of I-90 Friday afternoon through Friday night. Accumulations look to remain minimal at this time. 4) Quite and unseasonably cool for the remainder of the forecast period. **************************************************************** Quiet conditions continue across the region, with latest observations showing temperatures in the upper teens to lower 20s. Northwesterly winds during this time have remained fairly breezy, as gusts continue to range between 20 to 30 mph, resulting in wind chills in the single digits. Should see these gusts quickly diminish as we approach sunset, with a lull in winds likely for the first half of the overnight period. Will then see gusts increase again closer to daybreak as direction shifts to the S/SE. In regard to temperatures, look for overnight lows to plummet into single digits to teens with the aid of efficient radiational cooling. Similar to last night, winds chills will remain in the positive to negative single digits, with the coldest values along and east of I-29. We'll see notably warmer temperatures prevail Thursday as southerly flow increases low-level WAA across the region. As alluded to in the previous discussion, the biggest question remains centered on how much the recent snow will limit the overall depth of mixing. Areas with minimal to no snow cover could see high temperatures challenge the 40 degree mark, with a few locations in central SD even flirting with 50 degrees. That being said, for those east, expect highs to only rise into the mid to upper 30s. In terms of winds, have continued to trend values closer to a NBM/NBM 90th mix after collaboration with neighbors, which generally keeps gusts between 30 to 40 mph. Winds will then decrease heading into the evening, though gusts between 15 to 25 mph will still remain likely for much of the overnight period. .LONG TERM...(Friday through Wednesday) Issued at 246 PM CST Wed Nov 30 2022 Another warm day on tap Friday, though highs will follow a non- diurnal curve as a sharp cold front comes barreling across the region during the afternoon. Looking aloft, models continue to show a fairly pronounced shortwave progged to slide across the Northern Plains Friday afternoon through Friday night. As a result, have snow chances returning to the forecast, mainly north of I-90. Nonetheless, with overall moisture remaining fairly limited, do not anticipate much in the way of accumulations. Rather, the more notable story Friday remains focused on the strong winds along the advancing cold front. Similar to Thursday, have nudged both sustained values and gusts closer to a NBM EXP/NBM 90th blend after collaboration with neighbors. As a result, now have widespread gusts between 30 to 45 mph. Suspect we may even approach advisory level winds at times, based on latest guidance - however, have opted to keep values just shy of that threshold for the time being until higher confidence is achieved. Temperatures will take quite the dive by Saturday morning, as lows fall into the single digits. With breezy winds still in place during this time, expect winds chills to plummet into the negative teens to single digits - so be sure to bundle up if heading outdoors. Temperatures then look to moderate a bit during the daylight hours, as highs rise into the 20s to low 30s, with values in the 30s to 40s common again by Sunday. Otherwise, look for unseasonably colder temperatures and dry conditions to prevail for the remainder of the extended period as northwesterly flow builds aloft. Currently have highs largely in the 20s, with overnight lows falling into the single digits. && .AVIATION...(For the 06Z TAFS through 06Z Thursday Night) Issued at 1007 PM CST Wed Nov 30 2022 VFR conditions expected with plentiful upper level cirrus through the overnight. Main aviation concerns will revolve around winds, both at the surface and aloft. LLWS will set in through the overnight hours and continue until more robust mixing establishes mid morning Thursday. These stronger winds will begin to work toward the surface by 15-16z with southerly gusts in the 25-35 kt range into the afternoon hours. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...None. MN...None.

Wind chills will fall back into the single digits below and above zero tonight into early Thursday. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday. Southerly winds increase Thursday, with gusts of 30 to 40 mph expected. Strongest winds will be near and east of Interstate 29, especially across the Buffalo Ridge in southwest Minnesota, and into the Iowa Great Lakes. Winds will swing to the northwest on Friday, with gusts up to 40 mph at times Friday afternoon into Friday night. In areas near and north of Interstate 90, especially toward the Highway 14 corridor, the strong winds will accompany a chance of light snow Friday afternoon and evening. At this time, it appears that any snow accumulations will be light, but the combination of falling snow and gusty winds may cause reduced visibility and difficult travel. .SPOTTER INFORMATION STATEMENT... Spotter activation is not expected at this time.
