Some Clouds, Comfortable

Cloud cover associated with a digging upper air trough to our northeast kept temperatures in the lower 50s overnight. Skies are currently clear so it's possible we may start the day a bit cooler than current readings. The main brunt of the cold air associated with the trough will remain well to our north and east so we won't experience much of a cool down during the day. Passing clouds associated with upper air impulses and a cold front, however, will tend to keep temperatures from warming up too much this afternoon, but we'll still top out around 70. With a tightened pressure gradient in place, winds may also gust up to 25 mph at times this afternoon, especially during prolonged periods of sunshine. A cold front will push through this evening and will usher in a shot of cooler air overnight. I don't think the front will have enough moisture for any precipitation, but some lingering cloud cover will likely remain in place through early Wednesday morning. However, a brief windows does exist for clear skies and light winds to allow temperatures to drop like a rock tomorrow morning. Temperatures will be around 44 tomorrow morning. The big warm up is still in the works beginning tomorrow and lasting at least through the weekend. I still think we hit the mid 80s once or possibly twice by then.
