A break in the clouds

 NOAA

Here's why we can't see the sun today - clouds, drizzle and fog. There's a cold front headed this way from the west, with a brief respite from the gloom. We'll likely see a few more showers today, but by late afternoon - maybe during our drive home tonight - we'll start to see some changes.

First, we can look forward to some heavier showers, and maybe even a thunderstorm here and there. Forecasters expect winds around 20 mph, with gusts to 36 mph as the front pushes through. Here's the radar loop;.

Behind all that we should see clearing skies as the barometer turns and high pressure moves in. Forecasters at Sterling promise sunny skies tomorrow, with cooler highs in the upper 50s. We could slip down into the 30s Wednesday night.

But then, on Thursday, we fall back into the return flow from the departing high, which will throw more cool, damp Atlantic air onshore and up against the mountains in what meteorologists call a "cold air damming" event. The wedge of cool, damp air hangs on Thursday and Friday east of the mountains and prevents warmer, drier air from moving in at the surface. That's exactly where we've been for the last couple of days, too. High elevations to our west could even see some sleet Thursday.

From there the computer models begin to disagree. One says the next cold front will clear the region by Saturday, bringing us some April sunshine for the weekend, and highs in the 60s. Another says the rain will hang around until Sunday. Make mine sunshine.

Hello,

Like everyone else, I'm holding my breath for warmer temperatures.

Can you tell me (on average) when we can expect to see days with high temps of 75 Degrees? By that I mean, month and week, i.e. late April, early May, late May etc.

Thanks
Henry

The average daily high temperature for BWI reaches 75 degrees on May 18. Here's the May data: http://www.erh.noaa.gov/lwx/climate/bwi/Bwimay.txt

But we could do better than that. As we've seen this winter, Baltimore can see the 70s in any month of the year.
