FORECAST IN DETAIL

Did you remember to spring your clocks ahead by one hour? Well, at least any that don’t do it automatically? Daylight saving starts today, and despite increasing clouds, we’ll have mild air to enjoy during that extra hour of afternoon sunlight both today and tomorrow. Next chance of rain comes Monday night into Tuesday with a cold front that sends temperatures steadily downward during the latter part of the week. Is everyone as happy as I am about gaining the bonus hour of evening light?

Today (Sunday): Many people, including myself, associate the switch to daylight saving time with spring. Today fits the bill nicely with a warm and dry day in store and highs near 60 to the low 60s. Main difference from yesterday is some clouds to contend with, but partly sunny skies should be a perfectly fine complement to this welcome warmth. Confidence: High

Tonight: Partly to mostly cloudy skies hinder star-gazing and help keep us mild by trapping some of that infrared radiation instead of letting it escape out to space. Overnight lows should only dip to the upper 30s to low 40s. Confidence: High

Tomorrow (Monday): Many of us will be “feeling” the time change when our alarms go off, but Mother Nature does her best to put a spring in our step with another mild day. Highs head for at least near 60, and some model guidance suggests a few degrees higher. Our next rain-maker should hold off, though can’t rule out a late-day shower sneaking in from the west. Confidence: Medium-High

Tomorrow night: A warm and mild night accompanied by increasing shower chances, from 30% before midnight to 60% after. With mild lows in the mid-40s to low 50s, might be a nice night to keep the window cracked and listen for any showers. Confidence: Medium

A LOOK AHEAD

A full-blown rain seems likely by the Tuesday morning commute as a cold front swings through. The second half of the day may be salvageable, as it appears the rain will begin to depart after lunchtime, but of course timing is subject to change this far out. Breezes pick up later in the day and highs should reach at least the mid-50s, maybe higher with enough afternoon clearing. Showers are long gone by Tuesday night as winds from the northwest dry us off and cool us down to lows in the mid-to-upper 30s. Confidence: Medium

Wednesday could be breezy but should be otherwise tranquil, with cooler highs around the upper 40s to low 50s. Confidence: Low-Medium
