At first glance this forecast looked like a loser, but on closer examination I think it's going to be better than some expect. Today will be more sunny than cloudy despite the chance of an isolated late-afternoon shower or two. Moreover, Friday will definitely be a winner with sun and mild temperatures. Though the weekend won't be sunny and beautiful, showers may be more miss than hit at times -- with the best chance of rain Saturday night into early Sunday -- and highs in the mid-60s to near 70 won't be far from normal.

Today (Thursday): Mild conditions and mostly sunny skies are likely in the morning after fog burns off between 8 and 10 a.m. Clouds start to pop up in the afternoon and by late in the day an isolated shower or two is possible. Highs make the upper 60s to low 70s with winds from the northwest around 5-10 mph. Confidence: Medium-High

Tonight: Temperatures fall through the 60s in the evening as skies clear quickly. Winds continue light, about 5-10 mph from the west, as readings end up in the mid-40s (suburbs) to low 50s (downtown) by daybreak. Confidence: High

Keep reading for the forecast through Monday....

Tomorrow (Friday): We'll see plenty of sun for most of the day with highs once again in the upper 60s to low 70s and winds from the northwest near 5-10 mph. High clouds will likely be on the increase late in the day as a storm in the Midwest approaches. Confidence: High

Tomorrow Night: Clouds lower overnight, which should help to hold temperatures up with lows only in the upper 40s to mid-50s. We'll have a 20-30% chance of showers late with light winds from the southeast. Confidence: High


Expect a lot of clouds Saturday and the potential for some showers too. But for much of the day, they should be of the scattered and intermittent variety (30-40% chance of measurable rain). Highs should reach the mid-to-upper 60s with light winds from the southeast. More showers are possible Saturday evening, but best bet is that the real rain producers come overnight when a half-inch of rain or better should help wash more of that tree pollen from the skies. Confidence: Medium

Sunday probably remains mostly cloudy, but showers and possibly a few thunderstorms are again likely to be only scattered (40-50% chance of measurable rain). Morning lows in the low-to-mid 50s rise toward highs in the upper 60s to low 70s. Breezes pick up a bit from the southwest around 10 mph. Confidence: Medium

Monday should see morning lows again in the low-to-mid 50s. Partly cloudy skies in the morning could turn sunnier midday as highs reach the mid-to-upper 60s, before a line of showers and possibly a thundershower threatens to zip through in the afternoon. Confidence: Low-Medium

What are we looking at for cloud height and t-storms for Sunday? Might be flying a single-engine Cessna back from Boston. Concerned about embedded t-storms, convective activity and low IFR conditions.

So it looks like it is probably ok to put in some annuals now. I have had to postpone the exterior painting due to the rain.

Thunderstorms seem most likely late Sunday afternoon or evening and again on Monday, though this depends on timing of the warm front [wee hours of Sunday morning?] and cold front [midday to afternoon Monday?]. The closest to a washout we could see might be Saturday night. There's the possibility that cold air damming [CAD] could delay the warm front's progression through our area Sunday morning.

The low pressure area involved with this storm is likely to pass north and west of us, hence the diminished washout threat.

celestun100 - i say yes to annuals; I think Beltway, inward, is A.okay now. Safe from freeze!

chris_soule - I don't think these will go over 30,000ft.. but a cesna in any moderate t-storm sounds a bit.. well, I'd be very careful.

If we break into the warm sector Sunday, some isolated convection could develop in the afternoon. Would watch this closely.
