D.C. area forecast: Clouds, shower chances on the increase

April 28, 2013

3:40 p.m. Update: A slow-moving north-south line of showers made it into the metro area and will gradually exit from west to east during the late afternoon into early evening. Looks like we may see a lull in showers during the evening before chances increase again overnight or toward morning.

Not bad, but after yesterday, increasing clouds and p.m. shower chance doesn’t match up.

Tomorrow: Cloudy, 60-70% chance of showers. Near 60 to mid-60s.

FORECAST IN DETAIL

We don’t go back-to-back with the spectacular spring weather this weekend, but today is far from a total loss despite increasing clouds and a shower chance. The potential for steadier showers and cooler temperatures threatens to put a damper on Monday, before shower chances trend a bit lower Tuesday and especially Wednesday, when sunshine attempts a comeback. Warmer air tries to work back in toward midweek as well, though there’s no sign of really warm stuff in our immediate future.

Today (Sunday): Early sun quickly gives way to increasing clouds as low pressure approaches from the west.  Associated showers approach as well, but struggle to make eastward progress once they cross the Blue Ridge. Still, there’s a 30% chance or so of a few light showers mainly during the afternoon hours, especially west of D.C. The clouds hold temperatures down just slightly, with highs in the mid-60s to near 70. Confidence: Medium-High

Tonight: Shower chances increase to more like 60% during the evening and overnight, but any rain is likely to remain on the light to moderate side. Skies stay mostly overcast, and overnight lows are near 50 to the mid-50s with light winds from the south/southeast. Confidence: Medium

Tomorrow (Monday): Not the way we want to start the work week.  It’s sort of a “blech” day with steadier showers a threat (60-70% chance) during the morning and midday, even though the heavier activity may try to skirt by to our south and southeast, giving way to more of an off-and-on scenario later in the day.  Skies won’t brighten much through cloudy skies as highs probably stall out from near 60 to the mid-60s. Confidence: Medium

Tomorrow night: Winds take on more of an easterly component, and that means an overnight triple threat with the potential for occasional showers, drizzle and fog. Though as far as showers are concerned we’re back down a bit to a 50% chance and probably of the lighter variety. Temperatures don’t drop much under that overcast blanket, with lows ranging through the 50s. Confidence: Medium

A LOOK AHEAD

With low pressure lingering along the coast, we can’t quite break free of shower or drizzle chances for Tuesday. Any showers should be light and less numerous than Monday, but with a 40% chance of at least a few throughout the day. Skies are mostly to partly cloudy with highs in the mid-60s to near 70.  Shower chances drop to around 20% Tuesday night with lows in the 50s. Confidence: Medium

On Wednesday, a weak area of high pressure tries to nose down along the Atlantic coast.  That should be enough to limit shower chances to 20% or less, and to allow skies to brighten to at least partly sunny. Highs top out again in the mid-60s to near 70. Confidence: Low-Medium
