Friday Afternoon Forecast
Friday Night: Increasing clouds, Low 29°F
Saturday: Cloudy, High 39°F
Saturday Night: Chance of a wintery mix (60%), Low 33°F
Sunday: Mostly cloudy, High 35°F
Sunday Night: Overcast, Low 15°F
=============================================================================
General Discussion:
Temperatures will stay well above average this weekend after dipping below freezing throughout this week. Increasing clouds will start off this weekend and continue through the start of next week. There is 60% confidence of precipitation on Saturday night into Sunday with a wintery mix of rain/freezing rain and snow. If temperatures dip below freezing on Sunday, rain may freeze on elevated surfaces.

Key Messages:- Temperatures will remain above average this weekend dipping below freezing once again. Expect high temperatures to reach 35-40 °F for Saturday and Sunday.
- Chances of winter precipitation associated with an Alberta clipper will occur Saturday night into Sunday.
Friday night – Saturday afternoon
Cloud cover is expected Friday night into Saturday keeping temperatures colder. Clouds will significantly reduce radiational heating, allowing temperatures to remain low. The clouds will continue to increase and linger throughout the day Saturday before the next chance of precipitation occurs later Saturday night.
Saturday night – early Sunday morning
Chances for winter precipitation associated with the Alberta clipper system and frontogenesis will be expected Saturday night into Sunday morning. With the cold air mass (540 thickness) leads to dive deeper on what type of winter precipitation we will have. According to the GFS and NAM sounding there will be a warm nose leading temperatures above freezing. The sounding also reaches agreement with the type of precipitation being rain or snow, with confidence of snow remaining at 30%.Once snowflakes form in the dendritic growth zone it will pass through warm air. These snowflakes will melt into rain. Chances for freezing rain remain low but can not be unmentioned at this time. If temperatures go below freezing at 32 °F chances for freezing rain will increase. Further models and consensus of partial thickness and 850-700mb thickness agree the winter precipitation will be freezing rain or rain.The partial thickness (1530 line) and 850-700mb thickness (1305 line) intersect over our area. Chances for snow to make it to the surface does not remain zero but confidence lies at 30%.
Sunday morning – Sunday Evening
Sunday’s temperatures will remain similar to Saturday night’s low due to the cold air masses sinking into the col point, temperatures will remain cold and won’t vary as expected. A strong cold air mass will enter the area Sunday evening dragging temperatures below freezing (15-20°F). This cold air mass associated with a low pressure will present cloud cover and below average temperatures as we enter next week.
Impacts and Accumulation
Impacts remain low but be prepared if the rain freezes to the surface. Below freezing temperatures Sunday and the beginning of next week will have high chances frozen pipes damage to exposed or outdoor plants. As the possibility of ice on the surface remains low due to the warm nose on the soundings, rain may transition to freezing rain causing roads and sidewalks to become slick. Due to the winter precipitation remaining a mix, the snow accumulations remain extremely low with possible light dusting if snow reaches the surface.
Future forecasters should note progging another Alberta clipper rapidly developing lee side of the Rockies moving into the area next week where there is a col in place setting up strong frontogenesis.

Friday Morning Forecast
Friday: Increasing Clouds. 42°F
Friday Night: Mostly Cloudy. 27°F
Saturday: Cloudy. 41°F
Saturday Night: Cloudy with a Chance of Snow and Rain (60%). 35°F
Sunday: Mostly Cloudy. 35°F
=============================================================================
General Discussion:
Temperatures will be slightly higher today at 42°F, but will still dip below freezing, 27°F, overnight. Clouds will be increasing throughout the weekend as a low-pressure system moves into the region Saturday night, which brings a 60% chance of precipitation. Precipitation will likely start as snow and will transition to rain. If traveling Saturday night and Sunday, be sure to check the latest forecast and be prepared for wet surfaces and the possibility of ice as ground temperatures will likely be around freezing.

Key Messages:- An Alberta Clipper system will pass through Missouri late Saturday night and early Sunday morning.
- There is a 60% chance of precipitation, likely starting out as snow, but quickly switching over to rain. Negligible snow accumulation and small amounts of rain (less than 0.05”) are expected.
Friday morning – Saturday afternoon
This morning, mid-Missouri is experiencing light southerly winds around the western side of a ridge of high pressure just to our east. These winds will allow our high temperature for the day to climb well above freezing (42°F), a welcome thaw after a bitterly cold work week. While the sun will be visible for much of the day, clouds will steadily build in, with mostly cloudy conditions expected overnight tonight as some mid-level moisture enters the region. These clouds will linger during the day on Saturday, ahead of the next weather system which arrives Saturday night.
Saturday night – early Sunday morning
An Alberta Clipper system will form today in Canada, and quickly make its way down south, arriving in the mid-Mississippi valley late Saturday night. There is uncertainty about exactly what path the low pressure center of the system will take; the GFS brings the center over Columbia early Sunday morning, the NAM takes it through Iowa, and the HRRR plots a course near Kirksville. The exact path of the low will determine exactly what kind of precipitation will fall, so a southerly shift in the low’s path may abruptly change the forecast. We expect southerly winds to warm temperatures throughout the night (with an evening low of 35°F) ahead of the passage of the center. There is a 60% chance of precipitation, starting around midnight as snow, but as the low is likely to pass to our north, we expect warm air advection in the lower levels to begin melting snow before it reaches the surface by sunrise. Snow accumulation will be minimal, with only small amounts of precipitation (less that 0.05”) expected. Future forecasters should keep an eye on the position of the developing low, as its position critical in determining what exactly will happen when this system arrives.
The rest of Sunday
After the passage of the clipper system, winds at the surface will shift, coming out of the north, advecting cold air into the region. Temperatures will slowly sink throughout the day, with the day’s ‘official’ high likely occurring before sunrise. Temperatures will be in the mid-30s in the morning and the low 30s in the afternoon.
