« A touch of ice here, but mostly rain | Main | A heartwarming tale of Geminid meteors »

December 16, 2007

The thrill is gone

The biggest slug of moisture we're going to get from this storm is past now, and dreams of a snowfall have been washed away. Here's the water vapor loop from the GOES satellite.

Looks like they recorded about 0.9 inch of rain at BWI. We had 0.70 here at The Sun, at Calvert & Centre streets downtown. That's a little over 2 inches for the month, which puts us on a track which - if it continues - should give us close to normal precipitation for December. There's plenty of water in the streams this morning. Here are some more rainfall totals from across the region.

There was a little ice in some colder locations. Here's a rundown from the NWS.

The week ahead looks sunny for the most part, with a windy start as the low passes by and we fall in behind it with a northerly flow and tight pressure gradient between the low and the following high. It will be cold Monday and Tuesday, but warm to more seasonable readings as the week advances.

In the night sky, we can look forward this week to Mars' closest approach to Earth, on the 18th (55 million miles), leading up to opposition on the 24th - when the sun, Earth and Mars stand in a straight line, with Mars rising as the sun sets. The Red Planet is a brilliant naked-eye presence high in the northeast in the evening all month. But it's the best week of the year to take a look through a telescope.

We won't be as close to Mars Tuesday as we were back in August 2003 (35 million miles), or as close as we will be in 2016 (47 million). But it will be tough to tell the difference. And, it's the nearest we'll be for the next nine years. So don't miss the opportunity to get a look. And enjoy.
