Prairie Weather (Rural Roots Canada) – Drought eases, spring weather returns, seeding resumes
After the recent weather that brought wintry conditions on the first unofficial long weekend of summer, the weather this week will make a gradual return to becoming seasonally appropriate. The rain and snow across the prairies over the long weekend may not have been quite so welcome in most areas. The latest Canadian Drought Monitor shows a dramatic improvement in conditions across the prairies, with the exceptions of southern Alberta, southwestern Saskatchewan, and the Peace Regions.
Substantial precipitation and late-season snowstorms contributed to improved soil moisture, particularly in central and northern regions of Alberta, Saskatchewan, and Manitoba. By the end of April, the total area classified under moisture stress had shrunk to less than one-fifth of the entire Prairie landscape. Only 17% of agricultural land on the prairies is abnormally dry or in drought.
Although we are headed back to more seasonal weather, the change is gradual. Frost risk will be real for several nights early in the week before a gradual warmup takes hold mid-week. Seeding is already running behind historical averages across all three provinces, and this delays things further. The good news is that the second half of the week looks considerably better.
Monday
Peace Region
Conditions improve on Monday after a cleaner Sunday. Expect a mostly sunny sky with highs near 17, close to the seasonal average. Cloud builds toward evening, and overnight lows drop to around 4 degrees, cold enough to cause stress on any recently emerged crops but not into hard frost territory. The drying window is real on Monday. If your soils have had time to firm up, Monday is a reasonable day to evaluate field conditions and get equipment ready.
The Peace entered the season with sub-surface moisture rated 85% good to excellent, and any rain from the weekend system will need time to work off the surface before seeding. Seeding in the Peace sat at 0% complete as of early May, compared to a 5-year average of 6%, so pressure to move is high. Take Monday’s conditions seriously.
Alberta
Central and southern Alberta come out of a difficult weekend. The upper low that brought rain and wet snow to southeastern Alberta and mixed precipitation to the central and northern foothills will be moving away, but cold air lingers. Frost advisories were issued throughout much of southern and central Alberta over the weekend, and frost risk continues Monday night, particularly in low-lying areas and recently seeded fields. Showers are possible west of Highway 2 between Edmonton and the US border in the late afternoon. The showers will be scattered. While thunderstorms are not expected, the risk is not zero.
In central Alberta, highs reach the mid-teens on Monday with a low near 5 and clear skies overnight. It could be slightly colder near Fairview and Manning.
Fall-seeded crops and any canola that has recently cracked the ground are at risk. Provincially, seeding progress sat at 26% complete as of early May against a 5-year average of 37%, and this week’s early cold will not help close that gap quickly.
Saskatchewan
Monday is a recovery day for much of Saskatchewan. The weekend system delivered 10-25mm of rain to areas south and east of Saskatoon, with some pockets potentially higher. That moisture is welcome given ongoing seeding delays, but Monday’s highs will remain under 10 degrees near Regina with an overnight low around -1. Frost is likely in many areas Monday night, especially across southern Saskatchewan, where the sky will be clear.
Saskatchewan had seeded 16% of the crop by mid-May, well behind the 5-year average of 28%. The southwest is furthest advanced at 34%, and the northeast is at just 1%. Monday’s cold means many of the wetter fields won’t be ready to work for several days yet. Be patient and use Monday to check seeding equipment and catch up on pre-seed spray planning.
Manitoba
Rain continues to work through Manitoba on Monday morning. There may even be some snow in the area between Lake Winnipegosis and the Saskatchewan boundary. Winnipeg is looking at a high of 10 with a chance of showers through the day and a low near 3 overnight. Western Manitoba took 10-15mm through the weekend with some snow mixing in on higher terrain in Westman. Monday will be cloudy and cool. The Escarpment area may see lingering showers. Seeding operations should stay parked on Monday. Frost risk will materialize overnight as the sky begins to clear by Tuesday, so if you have any vulnerable crops in the ground, pay attention to early Tuesday morning.
Tuesday
Peace Region
A mix of sun and cloud, with highs in the 12 to 14-degree range, makes Tuesday one of the better field days of the week in the Peace. Scattered rain showers may spoil the day for some. The afternoon showers are more likely in the north Peace than the south. And the Alberta side is more likely to experience the wet weather than the BC Peace. Lows will again be around 4 or 5 overnight. If your soils firmed up on Monday, Tuesday gives you a legitimate seeding window, as long as the showers stay away. Wind will be manageable.
Alberta
Temperatures climb to the mid to high teens for most of central Alberta with mixed cloud. Edmonton sees a high of about 17 and a low of 6 on Tuesday night. Frost risk fades for most areas by Tuesday night, though northern Alberta locations could still see cool overnight readings above zero, but below 5. Southern Alberta warms more slowly, with frost still possible in low spots overnight Tuesday, where temperatures could dip to -2. Across the south, keep an eye on canola in early emergence stages and any pulse crops that were seeded in the past week.
Saskatchewan
Tuesday brings improvement, but it is not a seeding day yet for most of the province. Saskatoon climbs above 10 on Tuesday with increasing cloudiness by evening and a low just above the freezing point. That said, a frost risk is still present. Southern Saskatchewan reaches the low to mid teens, and remains relatively warm overnight, with a low of 5 to 7 degrees. Fields that took significant rainfall over the weekend will still be too wet to carry heavy equipment. Use Tuesday to assess field conditions and let soils shed moisture.
Manitoba
While most of southern Manitoba enjoys sunshine on Tuesday, the Red River Valley stays cloudy and cool with a high of 10, and drops to -1 overnight with frost risk. Eastern Manitoba near Portage la Prairie sees similar numbers with lows flirting with 1 degree. Tuesday continues to be a non-seeding day for most of the province. Any tender crops in the ground face frost risk Tuesday night.
Wednesday
Peace Region
Wednesday brings a mix of sun and cloud and highs again just below 20. This is the third consecutive workable day for the Peace if your fields are ready. Three good days in a row in the Peace in mid-May are worth taking full advantage of. Overnight lows hold near 4 or 5 degrees again.
Alberta
Outside of the Peace Region, Wednesday is a cool day for Alberta. Temperatures in northern agricultural regions will climb only to the 10 to 12-degree range on Wednesday with positive single-digit lows overnight, meaning frost risk is essentially gone for most of central Alberta by Wednesday night. It won’t be much different in southern Alberta, where highs will also be limited to the 10 to 12-degree range. Rain is expected throughout much of the province. The map below shows that most areas will get 3 to 5mm, with heavier amounts in Crowsnest Pass and in the Lloydminster area.
Saskatchewan
Wet weather will also reach Saskatchewan, especially central Saskatchewan, and southern areas west of Regina. Highs across the province will be in the 10 to 15-degree range. Overnight lows around 5 eliminate most frost risk. Fields that were too wet to work Monday and Tuesday won’t be workable on Wednesday either, especially where rain falls. In dry areas, Sandy-loam fields that drained quickly could be ready for seeding. Heavy clay in the east and northeast will need more time. Check soil conditions carefully before committing heavy seeding equipment. If you can push a finger into the soil 5cm without getting mud, you are probably close.
Manitoba
Sunshine returns to southern Manitoba on Wednesday, and highs will reach the mid to upper teens. Clouds will move into western Manitoba in the afternoon, and rain is not expected until the evening. During the day, western Manitoba should be drying rapidly. This is the beginning of a genuine fieldwork window for the province. Start with your lighter soils and work toward heavier ground over the coming days.
Thursday
Peace Region
Continued good conditions with highs in the upper teens and a mix of sun and cloud. Lows stay around 4 to 5 degrees overnight. Thursday and Friday are shaping up as your best consecutive seeding days of the week in the Peace. Keep equipment running where fields are fit.
Alberta
Thursday continues the warmup for Alberta. Central Alberta sees highs close to 20 degrees, and southern Alberta pushes into the mid-to-upper teens. Soil temperatures should be climbing toward the 10-degree threshold that canola germination requires at 2-5cm depth. Western and northern areas of the province will become mainly cloudy in the afternoon, but significant rainfall is not expected. Fort McMurray reaches 20 Thursday under sunny skies, giving northeastern Alberta one of its best days of the week. The window is open. Make the most of it.
Saskatchewan
Rainfall is again expected in southern Saskatchewan on Thursday, especially in southeastern sections. The rainfall will ensure seeding remains behind schedule. With the rain, temperatures will only reach the 10-12 degree range. In central and west-central Saskatchewan, temperatures will reach the mid to high teens, with no significant rainfall. This is a full seeding day for those regions of the province. Fields that drained adequately should be carrying equipment by Thursday. The northeast and east-central regions will still be challenging, particularly where excess moisture has been an ongoing issue. With the province sitting at 16% seeded against a 28% average, every fit day matters right now.
Manitoba
Winnipeg climbs close to 20 degrees on Thursday under a mix of sun and cloud with lows of 8°C overnight, bringing temperatures above average for mid-May. Rain in the early morning tapers off, except near the Saskatchewan boundary. Otherwise, Manitoba will be in good shape by afternoon for field work. Central Manitoba producers should be watching soil conditions carefully and moving when ready. This is one of the better days of the week for the province.
Friday
Peace Region
Another solid day with highs near 20 and mixed clouds. If you have been seeding since Wednesday, Friday will round out a five-day window that the Peace has genuinely needed. Overnight lows remain cool near 4, but well above frost thresholds.
Alberta
Friday continues the warm trend with highs reaching the high teens and low 20s across much of the province. Central Alberta could be a degree or two warmer than the south. If soil temperatures have responded to three days of warmth, canola seeded by Thursday should see reasonable germination conditions by the end of the week. Keep equipment moving on Friday. The weekend outlook beyond 7 days carries more uncertainty.
Saskatchewan
Western Saskatchewan will reach highs near 20. But from Moose Jaw east to Manitoba, it will be considerably cooler with highs near 13, and rainfall. Friday is one of the best field days of the week across the western part of the province. A Low in North Dakota will spin up some clouds and rain in southeastern Saskatchewan during the day, yet again delaying seeding operations there. Cereal crops and pulses that need to go in early to maximize yield potential are running out of runway. The 10-year average seeding completion for Saskatchewan is typically 70-80% by late May, so the pressure is real.
Manitoba
Winnipeg reaches the mid-teens on Friday with a mix of sun and cloud. Field conditions across western Manitoba would have been good by Friday, but the area will experience 5 to 10 mm of rain. Central and eastern Manitoba will be dry, but field conditions will be variable depending on how much moisture was received over the past few days. Some fields will be ready, others may not. This is the day to push hard on your remaining spring seeding acres.
Saturday and Sunday
Peace Region
Highs stay in the mid-to-upper teens both days under mostly cloudy skies. Overnight lows should stay above frost thresholds. Forecast confidence drops noticeably at this range, and the pattern has been active enough this spring to warrant caution about what develops early the following week. Keep seeding where fields remain fit and monitor updated forecasts heading into the weekend.
Alberta
Temperatures remain above seasonal normal through the weekend, with highs in the upper teens to low 20s across central and southern areas. No major precipitation system is clearly defined for Saturday and Sunday, but the active pattern of this spring means that it can change. If your fields have been cooperating through the mid-week window, the weekend should allow you to continue closing the seeding gap. Alberta’s provincial seeding sat at 26% complete against a 37% average as of early May, and a full week of workable conditions would go a long way toward getting back on track.
Saskatchewan
Highs near 20 are expected both days with partly cloudy skies and no precipitation currently forecast. If the pattern holds, this gives Saskatchewan producers nearly a full week of consecutive seeding days after the long weekend setback. That matters. With the province at 16% seeded against a 28% five-year average, a week of fit conditions could meaningfully close that deficit. The southwest and southeast should be in good shape to push hard. The northeast and east-central remain the problem areas, and even with a warm, dry weekend, heavy soils there will need more time to dry adequately.
Manitoba
The warm stretch continues with highs in the low 20s Saturday and Sunday across western, central and southern Manitoba. Winnipeg is forecast to stay in the 20-21°C range through the end of the week. Eastern Manitoba will be more variable depending on soil conditions following the weekend precipitation. Use the warm days to push your remaining seeding acres. The prairie pattern through May has remained unsettled, and frost risk as the growing season gets underway is something agricultural producers will need to keep watching, but the weekend window looks genuinely useful. Make the most of it.
