A mini January thaw is ahead Tuesday as a passing warm front turns us over to steady southwest winds.

The warm-up will be accompanied by increasing cloudiness, light showers and fog patches.

Mostly clear skies for the mainland tonight with partly cloudy conditions for Cape Breton.

It will still be chilly this evening with lows of -10 C to -6 C across the province.

I say this evening, because after midnight temperatures will begin to rise as winds turn south and southeast.

Coldest this evening with temperatures rising overnight as winds turn southerly. (CBC)

Increasing cloudiness during the day Tuesday. Scattered showers Tuesday evening and night. Not much to the showers, generally near 2 millimetres.

The increased humidity, plus the snow pack, will contribute to a dense fog in parts of the province Tuesday evening and night, so be careful about reduced visibility on roads and highways.

Winds will turn southwest tomorrow and increase to gust 40 to 60 km/h Tuesday afternoon and evening.

The warmer wind direction will push temperatures into a range of 4 C to 8 C and hold them steady through the night.

The warmest temperatures are expected in the Annapolis Valley and on the South Shore.

The warmer temperatures are unlikely to be record-setting for the province. Most high temperature records for a Jan. 26 run from the low to mid teens.

There is a nor'easter system that we'll have to watch for Friday.

Long-range computer models are consistent that the developing system will move past Friday. They are less consistent with the track and potential snowfall amounts. 

My advice would be to monitor your Friday forecast closely and be prepared to be flexible with your plans and travel.

Should you choose to scout out snowfall amounts at this point, be aware that these type of weather systems often undergo significant change this far out.

My first snowfall forecast will be on Wednesday for this system.
