It's another frigid morning over Southern MB with temperatures of minus 30 to minus 35 in Winnipeg this morning (-34 at my Charleswood station) Luckily winds are light today, so windchills are not a factor. Still, even walking at these temperatures will be enough to give exposed skin frostbite within a few minutes.. so bundle up!
Temperatures will start to moderate beginning tomorrow, with noticeably milder conditions on Wednesday with highs climbing back into the minus single digits by then (break out the sunscreen!) Before that however, we will have to deal with a blustery Tuesday as gusty south winds begin developing ahead of the milder airmass. So don't be fooled by Tuesday's forecast high of minus 10.. that's quite misleading as to what kind of day it will be. First of all, that high of -10 (if we even reach it) won't be reached until late in the day or evening. Temperatures will be in the minus 20s all morning and in the minus teens all afternoon. Second, those gusty southerly winds of 40 to 50 km/h with higher gusts will add a significant wind chill.. minus 35 to minus 40 in the morning moderating to minus 25 to minus 30 in the afternoon. In fact, Tuesday will feel just as cold as today even though actual temperatures are a good 10 degrees colder today (but winds are light.. it's all about the wind!)
Unfortunately, the milder temperatures on Wednesday will be short lived as colder air moves in again by the end of the week. Beyond that, temperatures are expected to remain generally below normal for the rest of January with occasional brief warm ups as a large scale upper ridge builds over the west coast, while an upper cold trough digs over Ontario and eastern Canada. This will give a northwest flow over the Prairies that will give Southern MB generally below normal temperatures for the next couple of weeks.
