Spring is always a tough time to forecast the weather as the battle between cold and warm air really heats up, but this forecast period is particularly tough. Once again we are stuck between a strong ridge of high pressure to our west, bringing record-breaking warmth to that region, and a large trough of low pressure to our east. This means our weather pattern will remain very active, with temperatures remaining well below average on most days.
This forecast period starts off tough, with an area of low pressure having just moved through our region. A second low will quickly follow on the heels of the first low as it dives southeastward across southern and central Manitoba overnight Wednesday and into Thursday morning. This low will likely bring a few centimetres of snow with it.
We’ll see a little bit of a warming trend develop late on Thursday and into Friday as yet another area of low pressure develops to our west. This low is forecasted to slide through the Dakotas late on Saturday and into Sunday, bringing clouds with showers over southern regions and light snow to more central areas of Manitoba. Colder air will once again move into our region behind the low as arctic high pressure slides south. We should expect temperatures to run near the bottom end of the usual temperature range for this time of the year during the first half of next week.
Looking further ahead, while the weather models are not showing any huge warm-ups, they are showing the current pattern we’ve been in breaking down around the middle of the month. The big question is, just what new pattern will develop?
Usual temperature range for this period:
Highs: 2 to 14 C
Lows: -9 to 1 C
