Discussion
After a relatively mild day today, the weekend will turn progressively colder and NW winds will increase in strength following the passage of two cold frontal systems. With the arrival of the initial cold front on Saturday, the atmosphere will become very unstable and there is a good chance for some rain shower activity and maybe a rumble or two of thunder. It is also possible that ice pellets mix in with the rain at times as the colder air filters into the region. Temperatures on Sunday will be confined to the 40’s for afternoon highs and below-freezing conditions are likely late Sunday night and again late Monday night. It stays colder-than-normal on Tuesday and will have to watch for the threat for some rain, ice and/or snow at night or on Wednesday as warmer air tries to return.
