The passage of the cold front tonight will bring showers to the area. Mostly cloudy conditions are expected through the rest of the week. Temperatures will be much cooler as well through the end of the work week, so make sure to have a jacket handy for trick-or-treating. Showers look to return during the day Friday.

Technical Discussion (The nerdy stuff we are discussing in class!)

 The upper level shows the development of an elongated trough moving eastward and passing through our area during the mid-week. Behind the front conditions will be cooler and mostly cloudy, and soundings also show drier air near to surface which rules out chances of precipitation on Wednesday and Thursday.   Although, on Wednesday night precipitation cannot be completely ruled out as models indicates moisture and upward motion at 700 mb. Friday afternoon, we will be located in the upstream side of the trough, with higher vorticity at 500 mb and upper level divergence, which indicates lower level convergence.
Soundings valid Friday afternoon present a saturated profile, upward motion and a veering warm advection wind profile. Southwesterly winds will bring moisture into the area. The presence of a lower pressure system in Northwest MO will support the potential of precipitation. Will defer to later shifts to figure out possible rain amounts.
