KEY MESSAGES

- Intermittent periods of flurries and/or very light snow will continue for most of the day with minimal accumulations. Additional accumulations tonight could lead to a tenth or two of snow mainly across southcentral SD.

- Near to above normal temperatures will persist over the next several days with the warmest conditions expected by Thursday.

- With no major system ahead over the next week, expect mostly quiet conditions to persist. However, a pattern switch could change things heading into early next week.

DISCUSSION

TODAY & TONIGHT: Another dreary day ahead! Similar to yesterday, most areas continue to be blanketed by low-level clouds (stratus) this morning with a few pockets of flurries. While accumulations are expected to be light, persistent low-level saturation and lingering lift associated with a few weak waves could promote intermittent pockets of flurries and/or very light snow throughout the day with minimal accumulations expected. Otherwise, lighter surface winds will continue across the area as highs peak in the 20s to low 30s. By tonight, persistent cloud cover will help keep our temperatures well above normal overnight with lows in the mid teens to low 20s. Looking aloft, another approaching wave will result in another push of light snow just after midnight tonight with an additional tenth or two of accumulations possible mainly across southcentral SD.

WEDNESDAY & THURSDAY: Looking into the midweek, any lingering precipitation should gradually dissipate by mid-morning on Wednesday. From here, upper-level ridging will continue to strengthen over the western CONUS promoting more northerly flow aloft. A warm front will gradually progress through the area from late Wednesday into Thursday helping us increase our highs from the 20s to mid 30s by Wednesday to the 40s to mid 50s by Thursday which would be a welcomed change. However, this will be short-lived as a cold front swings southwards into Friday gradually decreasing our temperatures into the weekend.

THE WEEKEND ONWARDS: Heading into the extended period, quieter conditions continue as the previously mentioned setup gradually breaks down across the western CONUS returning us to northwesterly flow aloft. Can't rule out a weak wave or two progressing through the area over the weekend. However, limit saturation will keep any measurable precipitation chances at bay through at least Monday. Otherwise, above normal temperatures will persist throughout the weekend with highs mainly in the mid 30s to upper 40s. While its pretty far out, its worth mentioning that some long-range guidance is picking up on a stronger system ejecting out of the Colorado Rockies by sometime early next week. While the details are far from certain, its worth monitoring the Tuesday to Wednesday timeframe for the potential return of accumulating snow.

A mix of VFR and MVFR ceilings will prevail for the majority of the period. Light snow showers located east of I-29 have begun to dissipate, and will gradually end over the next few hours. Winds are light and variable and will remain so throughout the period.

A second very subtle wave and WAA may trigger additional light snow showers shortly before daybreak for areas east of the James River. Confidence in these are low, and so only included a Prob30 group for KSUX where snow looks most likely. Any accumulation is expected to be light, a dusting to a tenth or two.
