The second round of heavy frost is forecast for today morning throughout eastern and western central Missouri and west-central Illinois. The ice might collect on untreated bridges, resulting in slick driving conditions.
Following its departure from the region at 3 a.m., a dry cold front is moving out of the area, causing wind directions to shift to the northwest in its wake as it leaves.
As a result of a low-pressure system moving eastward through the Northern Plains and into the Great Lakes area, the flow will soon revert to the southwest during the early hours.
Despite a strong low-level WAA, temperatures will reach the mid-40s to lower 50s before the following cold front associated with the low passes across the area.
The cold front will go across the area tomorrow afternoon and into the early evening, with just a change in the wind direction to the northwest, owing to a lack of moisture in the atmosphere, to indicate its passing.
Temperatures will be limited on Wednesday by modest CAA in the northwesterly flow in the low- and mid-levels in the aftermath of the dry cold front, keeping them around climatological norms despite high insolation a cloudless sky.
