AREA FORECAST DISCUSSION National Weather Service Sioux Falls SD 1038 PM CDT Tue Oct 31 2023 .DISCUSSION... Issued at 210 PM CDT Tue Oct 31 2023 - Cold with temperatures in the 20s for outdoor Halloween festivities this evening. Bundle up and wear extra layers! - Expect a breezy start to Wednesday with gusts in the 20s and 30s east of the I-29 corridor and especially near the Buffalo Ridge in southwest Minnesota. - Dry, colder than average weather continues through at least Friday with minimal impacts expected at this time. It'll be a cold night for trick or treaters in the region with temperatures in the lower to mid 20s this evening. Thankfully winds remain light as surface high pressure slides by to our south. Expect mostly clear skies overnight, but an increasing south wind and passing mid level clouds should keep temperatures from falling too dramatically with lows in the teens to lower 20s. Wednesday starts off breezy with a weak north-to-south front extended southward from Canada near the I-29 corridor. May see gusts of 30 to 40 mph east of I-29 for a few hours, especially for parts of southwest Minnesota along and downstream of the Buffalo Ridge where some local downslope wind effects will occur. Warmer air moves in for Wednesday through Friday, but temperatures will still remain below normal for this time of year as we linger in dry, cool northwest flow aloft. There is a signal in the NAM based models for low level stratus and perhaps areas of fog and flurries Wednesday night into Thursday as low level moisture gets trapped under a passing strong surface high. May need to monitor this period for potential for changes to the forecast. Otherwise generally no significant impacts are expected through Friday. Mainly dry weather is favored by ensemble guidance through Sunday. Though deterministic models suggest several clipper systems sliding through the Northern Plains or Central Plains from Friday through Tuesday, ensemble systems suggest a very low (<20%) chance of rain or snow until Sunday night. GFS, Euro, and Canadian ensemble systems paint a moderate (50-60%) chance of rain (or perhaps light snow depending on timing and temperatures) for Sunday night into Monday, but confidence in any details on this is very low at this time. && .AVIATION...(For the 06Z TAFS through 06Z Wednesday Night) Issued at 1033 PM CDT Tue Oct 31 2023 VFR conditions through the period, with guidance showing a low (~30%) chance of some MVFR or lower fog/stratus developing at the very end of the forecast period. Otherwise, expect mid and high clouds to prevail. Winds increase tonight and into Wednesday morning, with the strongest winds near the Buffalo Ridge in southwestern MN. Gusts of around 25 knots are expected. Direction shifts more southerly through daybreak, then becomes westerly by Wednesday afternoon. Light northwesterly winds return Wednesday evening into Wednesday night. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...None. MN...None. IA...None. NE...None. && DISCUSSION...BP AVIATION...SG
