AREA FORECAST DISCUSSION National Weather Service Sioux Falls SD 304 PM CDT Mon Apr 15 2019 .SHORT TERM...(This Evening through Tuesday) Issued at 303 PM CDT Mon Apr 15 2019 A surface warm front continues to surge north this afternoon, pushing temperatures well into the 60s and even 70s in snow free areas of the Tri-State region this afternoon. To the northwest, temperatures have struggled to reach the mid 40s thanks in part to light winds over the deep snow pack. Tonight: Mid-level frontogenesis will move through the area later this evening and overnight. Forcing isn't overly strong, and we'll be contending with a dry layer below 800 mb, but we should begin to see showers develop by mid-late evening. Instability isn't all that great once again, but will continue with very low probability of thunder. This activity will peak early Tuesday morning, and slide east of the area by daybreak Tuesday. Otherwise, we'll watch for some fog potential over the snow pack overnight. Tuesday: High pressures slides east across the Northern Plains and into the Western Great Lakes on Tuesday. We should see partly cloudy skies again, as cirrus returns from the southwest. Breezy easterly winds should help mix down warm low-level temperatures, with highs again peaking well into the 60s in many areas, with potential for 50s over snow cover. .LONG TERM...(Tuesday Night through Monday) Issued at 303 PM CDT Mon Apr 15 2019 Tuesday Night-Wednesday: Confidence again high in an unsettled period of weather from Tuesday night through Wednesday afternoon. As upper energy moves out of the southwestern US Tuesday, we'll begin to see return flow and warm advection aloft develop Tuesday afternoon to our south. Once the LLJ increases and an 850 mb front pivots northward, we'll begin to see elevated showers and thunderstorms develop and lift northward into Wednesday morning. Latest guidance continues to shift surface low pressure and the unstable surface air further southeast on Wednesday, leaving the CWA under more elevated instability during the daytime hours. Scattered thunderstorms will be possible through the day, with the greatest potential along and east of I-29. A cold front pushes through Wednesday afternoon, with stratiform precipitation ending from West to East by the evening. Amounts on average may approach 0.50-0.75" especially along the eastern CWA. Thursday: Cooler temperatures move in on Thursday as upper troughing swings through the Northern US. Soundings support some diurnal based activity, with highs in the 50s. Friday-Saturday: Mid-level heights begin to build early on Friday, signaling an increase in temperatures for the end of the week and through the upcoming weekend. Temperatures on Friday will rise into the 60s. A very warm day is expected on Saturday. Latest guidance continues to signal potential for 70s across a large portion of the region. Sunday: Models consistent with a cold front sweeping through the area on Sunday. This front will bring a chance for precipitation (mostly in the post-frontal airmass), along with cooler temperatures to start next week. && .AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon) Issued at 1206 PM CDT Mon Apr 15 2019 VFR conditions will continue through the next 24 hours. Light showers may begin to impact the area later this evening and overnight, however coverage uncertainty limits any prevailing mention in tafs. At this point ceilings will lower under 10K ft into Tuesday morning. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...NONE. MN...NONE. IA...NONE.
