AREA FORECAST DISCUSSION National Weather Service Sioux Falls SD 1028 PM CDT Tue Mar 29 2022 .UPDATE... Issued at 942 PM CDT Tue Mar 29 2022 Thunderstorms continue to lift off to the northeast through SW MN and NW IA with a decreasing severe weather threat mainly now confined to some small hail potential. As surface low, currently just north of Grand Island/York continues to slide northeastward through the overnight hours, attention will turn to the influx of cool air aloft and the mix with or change over to snow. Consensus of guidance continues to point toward any slushy accumulations remaining around or less than 2 inches. The outlier scenarios would give a small chance a couple different corridors of higher accumulations along various frontal circulations from 800 to 600 mb. The first potential area of locally higher amounts may exist from roughly Winner to arcing to Huron with the lower level circulation pointing toward another potential zone from roughly Tyndall to just west of Sioux Falls to Brookings. Again, these tighter, frontogenetically forced bands still carry high uncertainty but will be worth monitoring through the overnight hours. Final forecast change was to boost winds through the MO River corridor into the earlier overnight hours as higher momentum air cuts under the base of the low. A few locations may approach advisory criteria but lack of spatial extent precludes the need for a headline. && .SHORT TERM...(This Evening through Wednesday) Issued at 258 PM CDT Tue Mar 29 2022 In terms of severe weather, window of concern seems to be a very narrow window this evening (30.00z/7PM CDT to 30.05z/12AM CDT). Although SPC expanded both the Slight and Marginal Risks to the west with the 1630z outlook to encompass approximately the eastern half of the forecast area, expect the greatest risk to lie southeast of a Yankton, SD to Sioux Falls, SD to Slayton, MN line. Given the track of the surface low pressure (currently over north central KS), this area is most likely to see advection of dew points in the upper 40s and lower/mid 50s, with both breaks in clouds and WAA helping to aid this area in warming near/above convective temps this afternoon. Mid level lapse rates, particularly for northwestern IA, above 6.5 to 7 deg C/km indicate the potential for large hail. MUCAPE values over 1000 J/kg are supportive of severe weather as well. Although DCAPE values are not very high, storms (and even possibly shower activity) could mix down some wind gusts near/above severe threshold if gusts can break through the inversion. Storms could initially be surface based along the surface warm front as it lifts north, but with lack of surface support, would expect these storms to become elevated as they lift north/northeastward. Main threats look to be hail up to the size of ping pong balls (1.5 inches) and damaging wind gusts to 60 mph. Tornadoes are unlikely given the expectation of storms becoming elevated, lack of low level shear, and high LCL heights. After the thunderstorms/severe weather threat moves through this evening, attention turns to the wintry portion of the system, as colder air plunges southward on increasing northerly winds behind the departing low pressure. This should bring a transition from rain to snow from northwest to southeast after midnight into Wednesday morning, with wet slushy snow or rain through the day Wednesday. Similar to our recent daytime snowfall event, could be tough to see actual accumulating snow during the daylight hours, as rates are not expected to be extreme. That said, given the potential for some nocturnal snowfall, along with shallow warm layer, still looking at a potential for snowfall accumulations less than in inch for most areas, with 1-2" (locally higher) in the higher elevation areas of southwest Minnesota, and portions toward central South Dakota where the colder air will be in place longer, and there could be slight enhancement in response to weak mid-level frontogenesis. .LONG TERM...(Wednesday Night through Tuesday) Issued at 258 PM CDT Tue Mar 29 2022 Lingering snow will taper from west to east Wednesday night as the system pulls off to the east, possibly mixing with a little freezing drizzle on the back edge as we lose moisture in the mid levels above a deep stratus layer. Not expecting significant icing, though. With heavy focus on the near term today, did not make any adjustments to mid-long range portion of the forecast. Could see a couple of shots of light precip through this period, as various upper level waves move across the northern Plains, but confidence in specific timing/location is low at this time due to typical model differences at this range. Temperatures due look to moderate near to slightly above normal, with highs largely in the 50s this weekend into early next week. && .AVIATION...(For the 06Z TAFS through 06Z Wednesday night) Issued at 1025 PM CDT Tue Mar 29 2022 Thunderstorms have largely cleared the TAF sites to the east with the focus now on to a transition from rain to snow overnight, mainly at KHON and KFSD. While accumulations look to remain light for most locations (less than 2 inches) there is still some minor hints at a narrow stripe of higher totals. Additionally, during any periods where precipitation fades out, drizzle or freezing drizzle may take it's place. Again, confidence too low for official mention of this at this time. MVFR to IFR ceilings will become more common through the overnight hours with perhaps some improvement back to plain MVFR for the daytime hours Wednesday. Reduced visibility is possible with any snow. Finally, winds will pivot to an increasingly north and eventually northwesterly component into Wednesday morning as a low pressure system passes. Gusts as high as 30 to 40 kts are possible at times. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...NONE. MN...NONE. IA...NONE.
