FORECAST IN DETAIL


Once we get through today and tonight, the weather for the remainder of the week generally looks good. It’s mainly dry with high temperatures averaging in the 60s. We have small shower chances Friday into the weekend, but even that stretch is a vast improvement over Sunday and today.

Today (Monday): Some may start the day with fog, while others have some partial sunshine. But clouds quickly fill in by the afternoon with scattered rain showers likely (60 percent chance) as an upper level disturbance zips into the region. Temperatures aren’t much warmer than yesterday, only reaching the low-to-mid 50s. Confidence: Medium-High

Tonight: Rain showers are likely and may again cause issues/delays for the Orioles-Yankees game at Camden Yards. Totals aren’t heavy (probably around 0.25”), but enough to be a nuisance. Very late at night, clouds may start to decrease. Lows range from the upper 30s in the cooler suburbs to the low-to-mid 40s downtown. Confidence: Medium-High

Tomorrow (Tuesday): Improvement as weak high pressure builds over the area giving us partly cloudy and dry conditions. It’s still cooler than average, with highs only around 60. Confidence: Mediium-High

Tomorrow night: Partly cloudy and chilly, with lows ranging from the upper 30s in the cooler suburbs to the upper 40s downtown. Confidence: Medium-High

A LOOK AHEAD

On Wednesday, it turns a bit warmer as winds become southerly ahead of a weak cold front moving through the region late. Highs reach the low 70s, under partly sunny skies. The cold front passes by at night with just a few high clouds. Lows range from the upper 30s to mid-40s (downtown). Confidence: Medium-High

As far as sunshine goes, Thursday may be the week’s winner with high pressure directly overhead. Temperatures are a shade cooler than Wednesday but still quite pleasant, with highs in the mid-to-upper 60s. Clear and cool Wednesday night with lows in the upper 30s in the cooler suburbs to the upper 40s downtown. Confidence: Medium-High

If high pressure can hold, Friday is probably decent with at least partly sunny skies. We’ll have to keep an eye on a warm front trying to work northward, which could bring in some clouds and showers (30% chance). Highs are in the 60s. Partly cloudy Friday night with lows in the 40s. Confidence: Medium

As a warm front tries to move north while, at the same time, high pressure is focused to our north, we may get wedged in with cool, cloudy easterly flow Saturday. That would produce highs near 60 or even cooler. But, if the warm front wins out, we may end up with more sunshine and milder air well into the 60s. The warm front should be to our north by Saturday night, meaning mild lows mainly in the 50s. Confidence:Low-Medium

By Sunday, the next cold front approaches. It arrives with a chance of showers (30-40 percent chance) most likely late in the day (by timing could easily change). Around any rain, there are likely partly sunny intervals, with mild temps in the 60s to near 70. Confidence:Low-Medium
