More wind in the forecast...

The wind will be an issue again over the next couple of days, with a cold front approaching from the west Tuesday evening. Ahead of the front, temperatures will be in the low to mid 70s...but cooler air is on the way later in the week.

Rain from the front and is there a severe weather threat?

We'll get some decent showers from the frontal passage. Current data shows we'll likely see an average of 1/2 inch of rain Tuesday night. As for the potential of severe weather, there is some good shear but a lack of overall instability. That combined with the timing of the frontal passage makes the severe threat rather minimal. However, there will be some strong winds and a few thunderstorms may develop that cause some wind damage later Tuesday night, so we'll keep an eye on it.

Later in the week...

Quiet weather is on tap for Thursday, with a second front approaching on Friday. This front may kick off a few showers, but more importantly will bring a surge of chilly weather for the weekend. There is some moisture showing up on longer range charts for Saturday and with the colder, somewhat unstable air moving overhead with an upper trough swinging through, we may see some snowflakes in the air, particularly over the higher elevations north and west of Richmond.

Looking down the road...

After next weekend, the chill may linger into the early part of the following week (Mar. 10-11), with moderation by mid-week and a rain threat later in the week (Mar. 13-14). Beyond this, the pattern looks like it will be active and we'll have occasional surges of cold air. I have a feeling we're going to see a little snow this month in the Richmond area. La Nina years typically produce cooler than average springs, so don't be surprised by spurts of chill this month and next.
