A much cooler weekend...

We got a real taste of warm weather today, with temperatures up around 80 degrees. However, a big change is on the way overnight. A cold front will slide in from the north, bringing a few scattered showers and possibly a few rumbles of thunder. While we could catch a passing thunderstorm, there is no real threat for severe weather. The air is relatively dry as well and I don't expect a lot of rain. Behind the front, it will be much cooler this weekend, with afternoon temperatures in the 50s and early morning readings in the 30s on Sunday.

Onshore flow to produce more clouds on Sunday...

The flow will turn onshore around strong high pressure building off the New England coast on Sunday. This will bring in more moisture in the form of clouds and maybe even some light rain in spots by Sunday evening. It certainly will be rather cloudy to finish the weekend and even to start on Monday. I can't rule out a shower or two on Monday, but the wind will be turning to the south and that means we'll start to warm up again.

Next front arrives Tuesday...

The next cold front is on schedule to move through Tuesday evening. Ahead of this front, look for temperatures to soar back into the 70s. A few showers are likely with the frontal passage later Tuesday and Tuesday night (maybe some thunder as well), with another shot of "cooler" air to arrive on Wednesday.

The longer term...

These fast moving systems and overall weather changes will continue into the second week of April. The next system will probably impact the area on Friday 4/4 with a more substanial storm moving through the Ohio Valley and northern Mid-Atlantic on Tuesday 4/8. Each system will bring some warm weather ahead of it, followed by shots of cooler air on the backside.
