FORECAST IN DETAIL
A complicated weather system continues to influence our area into tomorrow. First, a weakening area of low pressure toward the Ohio Valley transfers its energy to a low off the coast today. The coastal low should bring today's heaviest rains to the Eastern Shore, but we could still see some occasional showers and drizzle in the D.C. area. Then, a lingering upper-level area of low pressure likely keeps clouds around into a good part of tomorrow, before nicer weather Thursday and Friday and an uncertain weekend.
Today (Tuesday): Look for light rain around the area through the morning hours. Shower chances decrease this afternoon to about 30%, though even if there aren't showers, drizzle could remain. Temperatures struggle to do better than the upper 50s to near 60. Winds from the northeast should be slightly stronger than yesterday, around 10-15 mph, creating a wee bit more of a wind chill. How much rain today? Probably around .10" or less. Confidence: Low-Medium
Tonight: The cloud deck wants to linger as upper-level low pressure is slow to vacate the mid-Atlantic. We still run a small risk (20% chance) of scattered showers. Lows should be in the low-to-mid 50s with light breezes from the north. Confidence: Medium
Keep reading for the forecast through the weekend...
Tomorrow (Wednesday): Call it a transition day as temperatures improve some 10 degrees to at least the mid-to-upper 60s for highs, but clouds continue to dominate with a 20% chance of a passing shower. I wouldn't be surprised, however, to see some breaks of sun, especially by afternoon. With enough sun, some locations could hit 70. Winds light from the north. Confidence: Medium
Tomorrow Night: Partly cloudy skies are anticipated with slightly warmer low temperatures ranging through the mid-50s. Look for winds to stay light and non-annoying. Confidence: Medium
Thursday and Friday will compete for best day of the week. Partly to mostly sunny skies are expected Thursday with highs in the mid-to-upper 70s, followed by a partly cloudy Thursday night with lows in the 50s. The warmest day of the work week comes Friday (not as warm, though, or nearly as humid as last Friday's rather steamy upper 80s) as highs head for near 80 or as high as the low-to-mid 80s under mostly sunny skies. Confidence: Medium
The weekend doesn't look like a washout (at least not yet), but there is growing concern that another system not unlike the current one could deliver increasing clouds and showers. Although forecast confidence is low, we'll keep the caution flag up with a 40% chance of showers, highs in the 70s and morning lows in the 50s. If the models trend wetter and cooler, then we may have to take highs down to the 60s. Confidence: Low
