The coolest air of the season...

A strong cold front is moving through Virginia (during the early morning hours of Tuesday), bringing with it a few showers, but more importantly, the coolest air of the season behind it. It will take some time for the chilly air to settle in, and afternoon temperatures will still rise into the low 60s in many places. But the next few mornings will be on the cold side, averaging close to 32 degrees for overnight lows in the city, with 20s in rural communities. Daytime highs will be in the 50s, a little bit below average for this time of the year.

The upcoming weekend...

Another system will dive southeast from the Great Lakes on Friday, redeveloping off the coast by Saturday morning. We will probably miss out on most of the precipitation, but a couple of showers may pass over the region later Friday and Friday night. The weekend looks like it will provide ample sunshine, with seasonably cool air over us.

And beyond...

Temperatures will likely moderate early next week, reaching the 60s on Monday and Tuesday. The next front will approach on Tuesday and our longer range computer data now advertises a pretty decent rain (and possibly chilly rain) developing for the mid-week period. Of course, I mentioned last week that the model data had initially hinted at something like this for this coming weekend, so we'll have to see how the situation plays out over the next couple of days. Stay tuned...

La Nina...

In my next post, I'll talk a little bit about La Nina, what it is and how it could impact our weather for the upcoming winter.
