The mild weather pushed in a little stronger than anticipated last week, and as a result, several locations saw record-high temperatures on Saturday (Jan. 16). It looks like the mild weather will continue for much of this forecast period, but I doubt we will see any more record-breaking temperatures… hmm, I seem to remember saying that about a Christmas storm.

The main weather maker for this forecast period will be the energy off the Pacific Ocean finally pushing inland. The large area of low pressure is forecast to push inland around mid-week and it should spawn a fairly strong area of low pressure somewhere across the U. S. Midwest by Thursday. Exactly how strong and where this low will move is still very much in the air, but here’s how the models are handling as I write this.

The main area of low pressure looks as if it will gather strength over Colorado and then slowly push to the northeast. We should see light snow move into extreme southern regions sometime late Friday. Currently it looks like the heaviest snow will stay to our south, but extreme southern regions could see snow last right through to Monday, bringing upward of 15 centimetres, with five or so cm expected over the rest of southern Manitoba.

If the low takes a more northerly path, snow totals may go up, but currently it looks like a more southerly path is likely. With a more southerly path, the chance of a cold air outbreak after the system is also more remote. So while we will see a cooldown to start next week, temperatures should still be around average for this time of year.

Usual temperature range for this period: Highs: -21 to -5C. Lows: -33 to -16C.
