Key Messages:
- Seasonably cold low temperatures remain for most of the week with another slight warming trend kicking off today
- Ongoing dry air advection paired with high pressure advancing from the west will continue our streak of calm weather into the weekend
Temperatures near freezing kick off the second half of the work week thanks to a center of high pressure digging in from the northwest. Dry air advection associated with this high pressure, along with its characteristic subsidence will keep the skies clear. Additionally, as the high pressure moves overhead our winds will remain calm at the surface. Thursday morning, winds are expected to shift to the south as our high pressure continues further eastward. This will expedite our warming trend leading to high temperatures in the mid to upper 60s, further increasing on Friday and into the weekend. While skies will be clear overnight, with calm winds, this southerly wind shift will support a slight uptick in warm air advection leading to increased low temperatures overnight.

Key Messages:
- Ongoing cold air advection will erode by Wednesday and warm temperatures up into the 60s.
- High pressure will dominate the region for the remainder of the week and contribute to dry conditions.
Current cold air advection has proliferated lower-than-normal temperatures in the region, with Tuesday’s high of 57 °F well below the seasonal average of 69 °F. Frost is possible overnight, as Boone County remains under a freeze warning until Wednesday at 9 am. Sensitive vegetation should be brought indoors or covered. By Wednesday at 08Z, this CAA will fade as a high-pressure system moves in from the north.
A jet streak is present over Missouri but will move out by Wednesday at 09Z and carry the current mid-level moisture and vorticity out of the area. These factors, along with a dominant high-pressure system over the region, will remain for the rest of the week and contribute to dry and stable conditions. An upper-level trough associated with low pressure over the northeast CONUS will move out by Thursday at 00Z and be replaced by a ridge attached to a high-pressure system moving in from the Kansas-Oklahoma border.
Model soundings show a dry profile throughout the rest of the week and support the expected dry conditions. Clear conditions overnight will allow for increased radiational cooling and allow temperatures to dip into the 30s overnight on Tuesday and Wednesday. Temperatures overnight Thursday will increase into the 40s as Winds will shift to the south on Thursday, contributing to the slight warming trend into the upper 60s during the day and into the low 40s Thursday night. Future forecasting shifts should note this warming trend and evaluate how it will persist into the weekend.
