Walking sideways in these pummeling winds is a chore, but it is not that cold and the rains are gone early. The REAL problem is having been spoiled the past two days. Get the Digit on Twitter| Discuss on Facebook

SPI: 4 (↑) - With two chances for flakes (early Friday and Sunday) you would think the odds would be better but this is a miserly winter when it comes to snow. Get the SPI on Twitter | Discuss on Facebook

FORECAST IN DETAIL


Showers should be out of the picture for all but the early risers today. Strong winds do a great job of drying roads off but are a pain. Looking ahead, once again mother nature taunts snow lovers with two moisture-starved systems late tonight and Saturday night. They produce likely no more than sweepable rather than the shovelable amounts.

Today (Thursday): There could be a few sprinkles in the pre-dawn but the main rains are long gone. What will linger are very stong winds from the west at 15-25 mph, gusting to 40 mph. Temperatures start the day around 50 and are unlikely to go anywhere despite clearing skies. Yes, Arctic air is pushing us back into winter whether we like it or not. Confidence: Medium-High

Tonight: The stars should be around for the evening and temperatures will rapidly drop from the 40s to the 30s. Clouds increase beginning about midnight with a few flakes likely to be flitting around before dawn. As for accumulation there is a 40% chance of enough to whiten the ground. However, roads should be safe due to the warm up they have gotten in the past two days. Lows end up in the mid-20s suburbs to near freezing downtown. Confidence: Medium

Tomorrow (Friday): There should still be some snow flurries in the morning with the same qualifications, mostly well under an inch (40% chance). The clouds should diminish quickly in the afternoon. Highs only in the mid-to-upper 30s are reinforced by breezes of 10 to 20 mph. Confidence: Medium

Tomorrow night: The winds calm as high pressure moves in and temperatures drop below freezing quickly. Lows should fall to mid-teens in coldest areas with low-to-mid 20s downtown. Confidence: Medium-High

A LOOK AHEAD

Groundhog Day (Saturday) dawns with few if any clouds so it is likely the mangy rodent calls for six more weeks of winter. But with the kind of winter we have been having does it really matter?! This should be among the minority of days this winter where temperatures actually run below normal with highs in the upper 30s to lower 40s. Clouds increase overnight and a few more snow flurries are possible late night (40% chance) with minimal accumulation. Lows fall to the mid-20s burbs to near 30 in the city. Confidence: Medium

Sunday could start out with a few morning snow flurries (40% chance) but again accumulations would be unlikely to exceed an inch and in most areas considerably less than that. Clouds break up enough for peaks of sun by afternoon with highs in the upper 30s to lower 40s. However, winds are likely to pick up briskly and make it feel notably colder. By evening clearing skies allow the stars out, but breezes keep it inclement. Lows drop to the 20s. Confidence: Low-Medium

Monday is quiet with partly sunny skies, calming winds and highs in the low-to-mid 40s for a pretty seasonable day. Confidence: Medium
