Today (Monday): Skies are variably cloudy today, probably starting off cloudier (especially east of town) with more intervals of sun during the afternoon. A few showers are possible (20-40 percent chance west to east), mainly east of town. Highs reach the low-to-mid 80s. Confidence: Medium

Tonight: A cold front moves into the region and could set off a few evening showers and storms. Lows range from the mid-to-upper 60s in the cooler suburbs to the low 70s downtown. Confidence: Medium-High

Tomorrow (Tuesday): We awaken to mostly cloudy skies and a 30% chance of showers. We probably see more in the way of sun during the afternoon with highs in the mid-to-upper 80s; a few showers and storms could pop in the afternoon, especially towards southern Maryland. Confidence: Mediium-High

Tomorrow night: By this time, the cold front is through the region and everyone is drying out. It’s clear to partly cloudy and pleasant with lows from the upper 50s in the cooler suburbs to the mid-to-upper 60s downtown. Confidence: Medium-High


Wednesday through Friday - much like this past week - are excellent in the mid-Atlantic. As Isaac’s remnants head through the Plains - potentially providing desperately needed relief from the drought - we are protected by high pressure. Skies are partly cloudy with highs each day in the mid-80s with overnight lows from the upper 50s to mid-to-upper 60s (downtown). Humidity levels are comfortable as well with dew points in the upper 50s to low 60s. Confidence: Medium

Depending on what’s left of Isaac and where it tracks, we may see some rain over the weekend. I favor Sunday at this point, but that’s a shot in the dark. After spending days over land, it’s unlikely we experience significant rain/impacts from what remains of Isaac. It’s mostly sunny more often than not in all likelihood. High temperatures are generally in the 80s with lows in the 60s (although highs could be a bit cooler if we have clouds and rain either day.) Confidence: Low
