TODAY’S DAILY DIGIT
A somewhat subjective rating of the day’s weather, on a scale of 0 to 10.

2/10: No one wins. Snow haters hate the snow. Snow lovers hate the transition to ice, then rain.

EXPRESS FORECAST

Today: Snow, transitioning to ice in afternoon. Highs: 25-30
Tonight: Wintry mix to freezing drizzle/drizzle. Temps rising into 30s.
Tomorrow: Plain rain. Highs: 45-50.

FORECAST IN DETAIL

Accumulating snow falls today until enough mild air arrives to switch it to sleet and freezing rain as we go through the afternoon. Driving on untreated roads will be challenging if not hazardous. Following some slick spots early Tuesday, plain rain falls washing away a lot of that snow. Wednesday through the weekend should then be mostly dry with moderating temperatures.

Today (Monday): After an overnight burst, snow may be slow to get going early on but should pick up by mid-morning. During the course of the afternoon, snow probably changes to sleet and freezing rain from south to north. Temperatures remain below freezing, keeping those untreated surfaces very slick. Highs range from 25-30. Winds are light from the southeast. Confidence: Medium

Tonight: Any lingering snow in our colder suburbs switches over to ice. But precipitation overnight, for the most part, should be light. Freezing rain and freezing drizzle transitions to plain rain and drizzle as the night wears on from southeast to northwest. By sunrise, most areas should be above freezing thanks to southerly winds. Confidence: Medium

Tomorrow (Tuesday): Be careful for lingering icy spots on untreated roads and sidewalks early on, especially in our colder areas. But temperatures are above freezing pretty much everywhere for much of the day. Plain rain is likely, washing away a lot of, if not all, the snow and ice. 0.5-1.0 inches of rain are possible with much milder highs from 45-50. Confidence: Medium

Tomorrow night: Rain showers may linger into the evening hours and then a third wave may try to push through late at night (40 percent chance). This final wave may bring a round of snow showers with little accumulation expected. Lows range from the low-to-mid-30s. Confidence: Medium

We see a big warm-up this weekend, with highs pushing well into the 50s and overnight lows in the 30s to near 40. Skies should be partly sunny. Confidence: Medium
