Memorial Day Weekend Forecast

The non-meteorological start of the summer season begins this weekend, and by Monday, it should feel like summer. A lingering reminder of the spring is still with us in the form of an upper air cyclonic flow, and this upper air feature will move away by Sunday.

Before then, the pool of cold air in the upper atmosphere may cause instability showers to form Saturday afternoon, although the models keep the higher likelihood to our north.

Beautiful weather– plenty of sunshine– for Sunday and Monday.

Sat 5/24: A mix of sun and clouds. High 74.

Sun 5/25: Sunny and pleasantly warm.. High 80.

Mon 5/26: Sunny and warm. High 84.

Warm Front moves through tonight

A warm front will move through this evening, with showers and perhaps a thunderstorm.


Milder temperatures and higher dew points follow. A generally unstable pattern through Saturday as a developing upper air trough allows instability showers especially Saturday afternoon. Things should dry out on Sunday, but the upper air trough may allow clouds to form Sunday afternoon.

This is my third incarnation of the’s website. The original, posted in 1997 used a static html format. In 2004, I moved the format to blosxom, a free scripting blog format. Blosxom was a big advance for me, but updating the website with pictures was more difficult than I ever would have guessed. I’ve been interested in exploring WordPress, from I thought using it would be difficult, but it’s really a piece of cake to install. I’m looking forward to broadcasting my forecasts on the web with this new format!
