A topic of conversation in Saskatchewan is usually the weather and 2 weeks into 2023 the top of weather talks has been the fog.
The number of days with fog advisories issued certainly has outweighed the days without, and to help better explain why the start to the new year has been foggy is Environment and Climate Change Meteorologist, Jesse Wagar.
“We are stuck in a very slack, very weak weather pattern which isn't allowing that low cloud and fog to fully be pushed out of the region. Most of the energy that pushes weather systems through, its either way up in the north in the Arctic or down in the states.”
Often, we have days with surface winds, which help push the fog out of the area. Those winds have not been present the last couple weeks, but could present themselves later this week, Wagar explains.
“There are some indications that maybe mid-week or near the end of the week we should start to see a shift in low surface winds which should help start to move the fog and the low clouds out. It does look like there is some warming that is coming towards the end of the week and that should help as well.”
Have you ever wondered how fog develops? Wagar shares insight on why the day can turn from clear to low visibility in a short matter of time.
“Generally, in the prairies we see a little bit of moisture injection from somewhere. Either we see some melting snow or a little bit of rain, and just the way the atmosphere sets itself up, it kind of traps all of that near the surface instead of allowing it to move elsewhere. We've also seen an inversion that sets up. What that means is, there's warm air stuck over top of cold air, and then that doesn't allow for mixing to occur, and it traps the low-level moisture at the surface.”
Relief from the recent stretch of foggy days seems to be on the horizon.
