The week ahead: Winter's back, back again

Jason Samenow @ 12:04 AM

It's going to be cold this week but not that cold (wait 'til next week perhaps...). Still, given the warmth we've recently experienced, get yourself ready for this week's chill, or you may be left shivering.

Today


Expect a brisk day as northwesterly winds blow in slightly cooler than average air. Under partly cloudy skies, temperatures will rise to near 40, after starting the day between 25 and 30. Overnight, winds should subside a bit and temperatures will fall to about 25 downtown, and 20 in the suburbs.

Tuesday


Northwesterly flow will continue, although the airmass should moderate a bit. There may be some high cloudiness from a wave of low pressure to our southeast, but we should have enough sunshine for temperatures to reach the mid 40s. Overnight, a weak cold front will swing through, and low temperatures should be in the mid to upper 20s.

Wednesday


Temperatures will cool slightly behind the front, and winds will again be northwesterly. Skies should be partly sunny with highs near 40. Overnight, it will be clear and very cold, with lows in the low 20s downtown and 15-20 in the suburbs.

Thursday


It should be a mostly sunny, but very cold day as Arctic air continues to stream in. High temperatures should be only in the mid 30s. Temperatures overnight will again fall sharply, dropping to the low 20s downtown and 15-20 in the suburbs.

Friday


Ahead of the next cold front, which may well be strong, temperatures will moderate a bit as winds turn southerly. Expect partly cloudy skies and highs in the mid 40s. Overnight, clouds should increase as the front approaches, with lows near 30.

Saturday


Expect mostly cloudy skies and a chance of snow showers or flurries as the cold front passes by. It will turn breezy and will be cold, with highs in the mid 30s. Skies should gradually clear Saturday night, but it will be breezy and very cold, with lows in the high teens and lower 20s.

Sunday


Sunny skies early may give way to increasing clouds late as an area of low pressure may approach from the south. A very cold airmass will be overhead, and highs may struggle to reach freezing.

Climatology


Average highs this week are in the mid 40s, with average lows in the upper 20s downtown and the mid 20s in the suburbs.

Last week's poll results


Close to 200 people participated in last week's poll: "What do you think of the lack of snow this winter?" 50 people "love it", 125 people "hate it", and 17 are "indifferent". Clearly, most visitors to this site like snow -- at least the vocal ones. This week's poll is now posted: "How much snow will fall the rest of the winter"?


Snow Lover's Crystal Ball

Next Chance of Accumulating Snow: Saturday, Feb. 11
Probability: 25%
Potential Impact:

Commentary: The Arctic front on Saturday may be of the variety to bring a brief shot of snow and a very light accumulation. Also, there are some weak indications a low could develop in the south next weekend. It is unclear whether it will slide harmlessly out to sea (80%) or come up the coast early next week (20%). The Crystal Ball does not have clear vision beyond seven days, but it's possible this potential storm will come into better view tomorrow and be featured accordingly...
