Forecast Discussion

Synopsis...

Cloudy skies in store for Thursday, with a chance of an isolated shower later in the day for regions in the N-NE. Once Friday breaks, expect clearing conditions and abundant sunshine through the end of the weekend. Temperatures will trend cooler through this forecasting period, with some warming expected on Monday.

Short Term...

A weak upper-level shortwave indicated by the WRF model will bring generally cloudy skies into the commonwealth for tomorrow, along with a slight chance of showers to the north and northeast in the evening. Once this disturbance passes, skies will clear out by Friday morning and should give way to abundant sunshine for the rest of this forecast period. MOS has temperatures through Monday trending cooler, with most regions maxing out in the upper 40s.

Long Term...

The next system to watch may come on Monday, as the WRF develops a fairly healthy cold front. Temperatures will warm up Monday and beyond ahead of this front. Initially, this system appears to prolong somewhat through the beginning of the week next week. Thanksgiving, at this point, looks to be at least cloudy if there isn't any rain. Regardless, the forecasting period through Sunday night lacks excitement but should leave students optimistic as they head home for break.
