Forecast: One more day before warmth invades

Another Mon. of record highs and storms ahead?

1:00 p.m. update: Clouds have been pretty thick so far, with a few breaks now trying to make inroads from the east. Highs seem more likely to end up closer to the lower end of the range previously anticipated, and perhaps a bit lower in spots.

FORECAST IN DETAIL

Today we take a climb back toward average high temperatures (now in the low-to-mid 60s) and still fall short thanks to clouds and a marine air mass. By Sunday night our lows might be near those same average highs. This time of year, that usually means a storm is cranking up somewhere to our west. Remember last Monday and the record highs set across the area? We’ve got a similar situation ahead -- perhaps even a smidge warmer if we get enough sun. Storm chances? Yeah, we’ve got that too.

Today (Saturday): There could be drizzle or patchy fog early, but breezes should keep it from being widespread. Otherwise, it’s mostly cloudy as winds with an easterly component continue, and warmer air beginning to stream in above keeps cool air trapped at the surface. There could be an isolated shower around during the day, but more places stay dry than may briefly get wet. Highs reach the mid-50s to near 60. Confidence: Medium-High

Tonight: If you’re headed to the United game, wear something warmish. Should your plans keep you out well past the evening, no worries for extra bundling. Temperatures pretty much hover near 50 or into the low 50s. Breezes are light from the south and southeast. Confidence: High

Tomorrow (Sunday): Clouds may initially be stubborn to depart, but an increasing south and southwest wind should scour them out enough for partly sunny skies by the afternoon. Highs should rise toward the mid-70s, though places north and northeast of D.C. could be cooler while places south and west near or top 80. There may be a late-day shower from decaying showers/storms that pop up over the high country to the west. Confidence: Medium-High

Tomorrow night: With the warm front heading well north and a very mild air mass streaming in ahead of the next cold front, lows probably aren’t much lower than 60-65. You might even be tempted to characterize it as humid heading into Monday, with dew points rising near or above 60. Confidence: High

A LOOK AHEAD

Monday gives us a glimpse of summerlike air (like last Monday) as another strengthening storm system heads from the Plains and Midwest toward Canada and sends warm air our way. Under partly sunny skies, highs probably reach the mid-to-upper 80s, and someone could even clip 90 (especially south and west). Record highs may be in jeopardy, particularly at Dulles (87) and BWI (85). DCA’s 91 is a little safer. Some A/Cs may be humming for the first time this year? Confidence: Medium

A cold front arrives late Monday into Monday night. It appears the best shot of storms comes during the evening through about midnight, but this could move forward or backward a few hours without trouble. There are similarities to last week’s event, so we’ll have to watch it as it closes in. Some strong to severe storms are possible. Confidence: Low-Medium

We lose a good 15 degrees or so on Tuesday, but that just means we get treated to a pretty delightful day. Soak up the sun with only a handful of clouds to dodge as highs reach the upper 60s to lower 70s. Confidence: Medium
