Area Forecast Discussion National Weather Service Sioux Falls SD 1046 PM CDT Thu Oct 31 2024 .KEY MESSAGES... - Small chance (<30%) of showers late tonight into Friday morning, mainly along the Hwy 14 corridor. Any precipitation would likely be rain although a brief period of freezing rain cannot be ruled out. Warm ground temperatures will limit impacts. - Above normal temperatures on Friday along with breezy winds will bring another round of elevated fire danger, mainly west of I-29. - New chances for rain return this weekend and continue into early next week. A few thunderstorms are possible. && .DISCUSSION... Issued at 231 PM CDT Thu Oct 31 2024 Overnight: Next wave lifting through the broader west to east running jet moves into the western Dakotas late tonight with the warm advective wing into the Hwy 14 corridor into the early morning hours. Overnight lows largely in the mid 20s to lower 30s with locations closer to the mid 30s through the MO River Valley. Another thing to monitor is fog potential over areas that received meaningful moisture this past night and haven't mixed out this afternoon (mainly portions of NW IA/SW MN). Friday: Previously mentioned wave should lift a more cohesive band of precipitation through northeast South Dakota with perhaps a more fractured area of precipitation from near/north of roughly a Chamberlain to Marshall line. Forecast soundings show a notable warm nose with surface temperatures below freezing. Any precipitation falling through this warm layer should help pull temperatures above the freezing mark (along with a quickly warming diurnal trend) with the primary precipitation being rain although wouldn't completely rule out a brief period of freezing rain/sprinkles around daybreak before temperatures can sufficiently warm. Ground temperatures well above freezing should limit impacts should any freezing precip occur. Any precipitation should be light and likely done by midday. Temperatures should quickly warm through the day back into the 50s to lower 60s with the help of breezy southerly winds gusting 20-30 mph. Fire danger west of I-29 where limited precipitation fell will rise into the high category. Saturday: Above normal temperatures to start the weekend with highs again in the mid 50s to lower 60s with upper level flow turning back out of the southwest ahead of a more widespread system into early next week. Sunday through Tuesday: Previously mentioned trough across the western CONUS begins to show its impacts on our region with increasing precipitation chances from Saturday night onward, although likely in different wave of precipitation as opposed to more persistent precipitation. Initial probabilistic guidance would suggest chances of 0.25 inch of liquid rainfall around or above 60% in any 24 hour period, with chances of 0.5 inch or greater generally below 50% for a 24 hour period. Precipitation chances, and for that matter rain amount probabilities, are likely still too broad-brush and will undergo spatial and temporal refinement as the the time period nears. Wednesday and Thursday: Cooler conditions arrive as the upper level trough swings overhead. Current forecast shows minimal precipitation chances although wouldn't completely discount the introduction of shower chances given the pattern. && .AVIATION /06Z TAFS THROUGH 06Z SATURDAY/... Issued at 1038 PM CDT Thu Oct 31 2024 Light and variable winds expected through the overnight hours, which could lead to some patchy fog in river valleys are areas east of I-29 which saw more precip and stratus during the day Thursday. Models have continued to decrease coverage of any fog, so confidence is low in occurrence. If fog develops, do not expect any impacts to TAF sites (should be further to the east). Otherwise, winds increase and shift southerly through the morning and afternoon hours Friday, gusting around 25 knots. Guidance has slowed precipitation onset timing for the James River Valley to near to after daybreak (closer to 13-14z), and adjusted the PROB30 group at KHON accordingly. Expect most if not all of the precipitation to be rain, although if precip starts a bit sooner, an hour or two of freezing rain can't be ruled out - although no impacts are expected. Other than patchy fog and precipitation, VFR conditions prevail. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...None. MN...None. IA...None. NE...None. && DISCUSSION...Kalin AVIATION...SG
