12/12 – The Chief’s “Spring-Like Conditions Continue” Monday Morning Forecast

This warm , humid air mass will continue as a high pressure spreads east over the Mid Atlantic. The southerly/southeasterly winds really begin to ramp as a potent storm system upstream develops over the Plains. This will be the system that could bring some strong to severe weather to our region by midweek.

Looking at the midweek situation, the slower trend continues as a disturbance continues to deepen further across the high plains and eventually spreading east over the Midwest to Texas. Timing is a bit hectic still with the models slowing down. A band of convection is projected to develop late Tuesday just upstream and gradually traverse the area through late Wednesday or perhaps even into early Thursday morning. This will bring the potential for excessive rainfall and flooding, along with isolated tornadic activity possible.

Focusing beyond the departure of the severe weather/heavy rain event, in the long-range will be cold weather. Strong cold air advection will remain in place during the day on Thursday with clearing conditions. CAA/cooler air on top of warmer shelf waters will keep some clouds in nearshore and marine areas, but should filter out throughout the day. High temperatures will reach the low to mid 60s with chilly northwest breeze. Friday night into Saturday morning and again Saturday night, went with the coldest temperatures near to or right at freezing temperatures for the northern half of the area.
