FORECAST IN DETAIL

Two different weather regimes define the upcoming week. We begin the week with a warm and moist regime bringing unseasonably mild air and the occasional chance of showers. Mid-to-late week, we transition to a dry and seasonable regime with cooler but sunny afternoons and clear, crisp nights. That regime may last into at least part of Sunday, though the weather pattern becomes a little more blurry by Halloween night.

Today (Monday): The day probably gets off a relatively tranquil note, with some partial sunshine and mild temps. Toward afternoon, clouds increase with a better than even (50-60%) chance of developing showers. An isolated rumble of thunder could even be heard as a wave in the atmosphere approaches. Highs reach the low-to-mid 70s. Confidence: Medium

Tonight: Shower and isolated thundershower chances continue, but diminish from west to east between about 7 p.m. and 11 p.m. With persistent flow from the south and cloud cover at times, overnight lows are mild - from 56-60 (suburbs-city). Confidence: Medium

Tomorrow (Tuesday): It's clear that Tuesday is mild, it's just a question of how mild or even warm. Highs have little trouble reaching the low-to-mid 70s but could spring into the upper 70s or around 80 if we get enough sun. We should get a break from rain showers, though a brief, isolated shower could (20% chance) pop-up somewhere in the afternoon resulting from the tropical flow from the south. Sky conditions vary from partly to mostly cloudy. Confidence: Medium-High

Tomorrow Night: It feels more like a summer evening than a fall one. Steady breezes from the south accompanied by a touch of humidity mean temps only slowly fall back from the 70s into the low-to-mid 60s. Toward morning, some showers are possible (35-45% chance) as a cold front approaches.Confidence: Medium

A LOOK AHEAD

The cold front slowly moves through the region Wednesday, with a 40% chance of showers in both the morning and afternoon. Despite the scattered, intermittent shower chances, there may be some intervals of sunshine. And a push of warm air ahead of the cold front helps temps climb all the way up to 75-80. Winds pick up and shift from the south to out of the west. Clearing and breezy Wednesday night, with lows from the upper 40s to mid-50s (suburbs to city). Confidence: Medium

High pressure builds into the region Thursday through Saturday -- that means sunshine and a return of dry weather. Temperatures trend cooler during this stretch, with highs 70-75 Wednesday falling to 60-65 by Saturday. Overnight lows also fall, with lows in the 40s Thursday night and the mid-30s to low 40s Friday and Saturday night - when scattered frost is possible in the colder suburbs. Confidence: Medium-High

Halloween Sunday most likely remains sunny and dry for the first half of the day, but a disturbance approaching the region from the northwest could bring some clouds by afternoon and even a slight chance of showers (20%) at night. The forecast for the second half of the day is particularly fuzzy, so keep checking back. Confidence: Low-Medium
