10/18 – Rob’s “Chilly Start To The Workweek” Monday Morning Forecast

[videoembed][/videoembed]Fairly benign weather continues a couple more days with just temps and dew-points to consider. A fairly weak high-pressure system will be tracking across the Mississippi Valley today and Tuesday. This will be the start of some moderating temps. Highs to remain below normal today, reaching climo tomorrow. Dew-points could be back in the 60s by the end of the day Tuesday. While this occurs, a few coastal showers may begin to develop late in the day. An upper-level disturbance centered near the Great Lakes, will aide in weakening the high-pressure and draw deeper moisture northward across the area. Shower and a few thunderstorms will develop on Wednesday.

The upper support with an associated surface front should then begin to move through the area from Thursday afternoon into Thursday evening. There will be enough moisture will be in place to support scattered shower and thunderstorm development into the afternoon hours.

The front and parent upper level trough axis will continue to push east of the area Thursday night into Friday morning, and expect to see the best chance of shower and thunderstorm activity shift into the coastal waters over this time frame. The atmosphere will turn increasingly stable with limited cloud development expected for both Saturday and Sunday. Significant cold air advection is not expected in the wake of the front, and temperatures should be near average through the weekend.
