FORECAST IN DETAIL

For four consecutive days, temperatures have not escaped the 40s and have been about 10 degrees below average. Our average high is now 60 degrees and I don’t see us reaching that this week - at least through Friday. Not only is it going to be chilly, but also wet at times, especially during the second half of the week And believe it or not, we may still not be completely done with snow...

Snow Potential Index: 1 (→) - Chances are low but can't completely rule out flakes Wednesday and Friday. The SPI lives another day.

Today (Monday): Pretty much everyone starts their day below freezing. Some morning sunshine warms us through the 30s but high clouds from a weak disturbance passing by to the south may slow the mercury’s ascent a little. It’s a brisk late March afternoon, with highs from the mid-40s to near 50 and winds from the north at 10 mph. Confidence: Medium-High

Tonight: Skies become clear and it’s the fourth straight night with low temperatures reaching to or below the freezing mark ranging from the mid-20s in the colder suburbs to right around 32 downtown. Confidence: High

Keep reading for the forecast through the weekend...

Tomorrow (Tuesday): Probably the nicest day of the work week, abundant sunshine helps most spots near or pass the 50-degree threshold. But the projected high in the low 50s (mid-50s south of town) is still about eight degrees below average . Confidence: Medium-High

Tomorrow night: Clouds increase ahead of the next fast moving disturbance with a slight (20-30%) chance of light rain or snow towards morning. Lows range from 30-35 (suburbs-city). Confidence: Medium

A LOOK AHEAD

Light rain is likely Wednesday which may begin as snow or mixed rain/snow. The best chance of seeing snow is in the mountains. It’s a raw, cloudy day with highs in the mid-40s. Precipitation ends Wednesday evening as the responsbile area of low pressure scoots off to the northeast. Clouds slowly decrease with overnight lows in the 30s. Confidence: Medium

High pressure may briefly build back in Thursday. But with chilly flow from the northwest, we’ll probably only manage highs in the low 50s or so. Increasing clouds Thursday night with a slight chance of rain or snow toward morning, with lows 30-35 (suburbs-city). Confidence: Medium

Another area of low pressure brings strong prospects for precipitation Friday. We’re probably looking at rain with snow mainly confined to the high elevations , but we’ll keep an eye it. With the clouds and precip, it’s chilly with highs only 40-45. There’s a chance the precipitation lingers into Friday night with lows in the 30s. Confidence:Low-Medium.

The weekend probably dries out and may warm up modestly. Highs Saturday remain chilly, in the low-to-mid 50s and it may be on the breezy side. By Sunday, maybe we get closer to 60 after Saturday night lows in the upper 20s to mid-30s. Both days look mostly dry (although a little precip could linger into Saturay morning and some light showers could move in late Sunday.) Confidence:Low-Medium
