Environment Canada has issued a frost advisory for Saskatoon and all of central and southern Saskatchewan for frost expected Tuesday night into Wednesday morning.
A ridge of high pressure building over the Prairies will bring clear skies and cold overnight lows Tuesday night with temperatures expected to be between 0 and -3 degrees by Wednesday morning.
The agency recommends taking preventative measures to protect frost-sensitive plants and trees.

August 2018
August was slightly cooler and way drier than normal in Saskatoon.
Daytime highs actually trended a tenth of a degree warmer than normal, but overnight lows were over a degree colder than normal, which pushed the average temperature in the month half a degree below seasonal.
Precipitation-wise, the airport only recorded 17.2 millimetres of rain throughout the month, which is only 40 per cent of the normal amount of 42.6 millimetres that’s typically recorded in August.
Saskatoon forecast
Tuesday
It was a cooler start to school as temperatures fell back to 7 C following a below seasonal Labour Day long weekend in the city.
Breezy northwesterly winds kicked in during the morning with gusts pushing toward 40 km/h as we hopped into double digits before noon.
Breezy winds stick around all afternoon as we struggle to make it up to a daytime high in the mid-teens under a mix of sun and cloud.
Tuesday night
Clear skies combined with a high pressure system passing by and light winds will create perfect conditions for frost to form as temperatures slide down below freezing by a degree or so overnight.
Low-lying areas could see a killing frost in areas with the mercury sliding a few degrees below freezing, so be sure to cover or bring in any frost-sensitive plants.
Wednesday
Jackets will be the order of the day with a cool start to the second day of school, but blue skies and sunshine combined with a breezy southwesterly wind will help warm us right up during the day.
You can throw those coats aside on your way home from work and school as we’ll make it back into the low 20s by afternoon with just a few clouds filtering through.
Thursday-Friday
The rest of the short work week ahead will be a bit warmer as an upper ridge ushers back in the heat under a mix of sun and cloud with a slight chance of showers on Friday.
Temperatures should make it up to around 22 C Thursday before springing up into the mid-20s to wrap up the week on Friday.
Weekend outlook
There still is some uncertainty with the weekend outlook, however at this point a system is expected to bring in clouds and a chance of rain Saturday into early Sunday before some late weekend clearing.
Daytime highs should make it into the low-to-mid 20s Saturday before falling back toward the teens on Sunday, however you will want to keep checking back in as we refine the forecast in the days ahead.
