241 FXUS63 KFSD 111117 AFDFSD Area Forecast Discussion National Weather Service Sioux Falls SD 517 AM CST Tue Nov 11 2025 .KEY MESSAGES... - Breezy winds today with gusts at times to 35 mph. - Temperatures continue to climb during the work week. Well above normal temperatures through the late week and into the weekend, 10 or more degrees above average. - Dry conditions persist through the work week with our next rain chances (20%-30%) returning later in the weekend into Monday. && .DISCUSSION... Issued at 247 AM CST Tue Nov 11 2025 THROUGH TONIGHT: Short wave continues to move through this morning, diving southeast across the area. Strong WAA ahead of the front and southerly surface flow has aided in keeping temperatures steady, if not warming, overnight. Have seen some stronger winds this morning with gusts at times to 35 mph across southwestern MN and into tapering down into adjacent areas of northwestern IA and southeastern SD with strong WAA and a stronger jet in place. Can`t rule out some flurries/sprinkles through daybreak. For the rest of the day, we`ll see breezy conditions with winds shifting back to the northwest behind a surface front. Gusts through the day 25 to 35 mph and direction shift from southerly to northwesterly. We`ll warm into the mid to upper 40s for areas with snowpack, and into the upper 50s and lower 60s for the snowless areas of south central SD. Tonight, surface high slides into the area. Clear skies expected with lows falling into the upper 20s and 30s. WEDNESDAY-FRIDAY: Dry weather is expected through the end of the work week as ridging builds aloft over the western CONUS, sliding east through the second half of the work week. A couple of weak short waves track through the northwesterly flow, but a lack of moisture keeps the forecast dry. Predominantly southerly surface flow is expected, which in addition to warming temperatures aloft will keep temperatures above average for mid November. Friday looks to be on the breezier side. Highs in the 50s and 60s, with even some 70s possible across south central SD by Friday. Lows also climb 10 or more degrees above average, in the 30s to even 40s by late week. For reference, climatological normals are mid 40s for highs and mid 20s for lows. SATURDAY-MONDAY: Looking ahead to the weekend and the start of next week, pattern begins to shift with troughing moving into the Plains states. 11.00z guidance has trended slightly slower from both the 10.00z and 10.12z runs with the exit of the ridge Saturday and the timing of the mid/upper trough. Still some uncertainty in the details of this pattern. First comes with the timing and strength of the surface front through the day Saturday. Flow aloft looks to be split through the weekend and into early next week, with northern trough moving across the northern Plains Sunday and the southern closed low sweeping north early next week. With the later trends, better rain chances now look to be Sunday and Monday. However, probabilities of a tenth of an inch of liquid equivalent during this time are falling as well, closer to 30-40% east of I-29, decreasing as you move west. Temperatures through the weekend remain above normal, cooling to near normal early next week. && .AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/... Issued at 514 AM CST Tue Nov 11 2025 LLJ keeps LLWS in place for areas south of I-90 through mid this morning. May see some additional LLWS develop tonight, but given the marginal conditions and lower confidence, have kept mention out for now. Otherwise, winds may occasionally gust around 25 knots this afternoon, shifting to a more northwesterly direction through the morning hours. VFR conditions expected through the period, with high clouds clearing later today. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...None. MN...None. IA...None.
