No major changes in the forecast update from Monday. Expect the remnants of now Hurricane Laura to pass to the south of the St. Louis region on its track eastward, bringing a chance for showers and/or thunderstorms around mid-day. In addition, winds are likely to increase as the outer edges of the storm approach; sustained winds are expected around 10-15 mph with gusts upwards of 25 mph. Above normal low temperatures will be present in the morning with seasonal high temperatures in the afternoon.
A cold front following immediately behind the post-tropical system will bring a slight chance for isolated showers and/or thunderstorms during the morning, with precipitation chances diminishing before noon. Winds will shift to the northwest behind the front, though at around the same speeds anticipated for Friday; similar temperatures are also expected. Partly cloudy skies are expected behind the front and will continue into Sunday.
The northwesterly winds on Saturday will cool temperatures overnight, with a low expected in the mid 60's on Sunday morning. A high pressure system passing to the northeast will shift winds to the east to southeast during the day, allowing for temperatures to warm again into the low 80's. The continuing partly cloudy conditions will persist into the afternoon when upper level cloud cover is anticipated to build in.
