We have a winning weather pattern for at least next 72 hours with solid sunshine, comfortable daytime temperatures in the 70s, and cool overnight lows. In the Dog Days of summer, this is a sort of period we can look back on fondly- a real spring crowd-pleaser. I’m still suspicious about Sunday though as a low pressure area near the coast could bring in some clouds and maybe even some shower chances late Sunday into Monday. If the low fails to visit, temperatures should go warmer (80s).

Today (Thursday): Today offers an excellent excuse for an extra walk outside as temperatures are as comfortable as they can get. Solid sunshine allows morning temperatures in the 60s to excel to afternoon temperatures in the middle 70s. Light winds from the north. Relative humidity is going to be low, so my only concern is that any lingering or newfound pollen may be floating around again for our biggest allergy sufferers. Confidence: High

Tonight: Pleasant with clear skies and cool temperatures. It may actually be too cool in the outer suburbs with mid-to-upper 40s there and more like mid-50s in the city. Confidence: High

Tomorrow (Friday): Mostly sunny skies and continued pleasant conditions prevail. Highs in the upper 70s with light winds. Humidity is as low as you can go with dew points still in the 40s to maybe 50. Confidence: High

Tomorrow night: Mostly clear and cool with lows in the upper 40s in the outer suburbs to middle 50s in the city (although for anyone out for the evening, the city will likely retain comfortable 60s until well after midnight). Confidence: High


Saturday looks great with mostly sunny skies and highs in the upper 70s to low 80s. The coastal areas out to our east could see cooler weather with more cloudiness, especially by afternoon. Saturday night is partly cloudy with lows in the 50s to around 60. Confidence: Medium-High

Sunday is still a tricky story as the weather guidance is divided. Either we have a nice, but slightly warmer day with mostly sunny skies and highs in the low-to-mid 80s or we see increasing afternoon cloud cover and cooler highs stalled in the low-to-mid 70s with possible light showers toward evening and Sunday night. For now, I’m going to favor the warmer/nicer route, but our confidence is low for this time period. Lows Sunday night are probably in the 60s either way. Confidence: Low

Monday looks partly to mostly cloudy with highs in the 70s and lows that night in the 50s-60s. A few light showers are also possible. Confidence: Low
