One last warm day before things go sideways heading into the May long weekend.

• Hourly and 7-day forecast on our CTVNewsEdmonton.ca weather hub

Temperatures will climb to the low 20s under mostly cloudy skies today and the wind should be light for most of the day.

But...the wind starts to gust tonight and it’ll be howling throughout the day Thursday. The strongest wind speeds for the Edmonton area will likely blow through Thursday morning and early afternoon, gusts in the 60 to 80 km/h range.

Those gusts may ease a bit Thursday night, but we’re still expecting windy conditions for Friday... just not AS windy as Thursday.

Gusts will be in the 40-50 km/h range through at least the first half of the day Friday.

It’s all thanks to a deep area of low pressure that’ll develop over south-central Alberta on Wednesday. That system then quickly moves off into southern Saskatchewan Thursday.

The system will bring showers and/or periods of steadier rain to most of the province. The heaviest/steadiest rain will likely fall in eastern Alberta and in the Jasper/Nordegg region.

For the Edmonton area, we’ll get some rain late tonight and through Thursday morning (amounts uncertain and likely highly variable across the region).

There’s also a chance of some showers Thursday afternoon and even the possibility of a few scattered showers Friday/Saturday.

BUT, overall, this really looks like more of a wind storm than a rain storm for Edmonton and area.

There’s also a big cool down coming. With the upper ridge moving off and being replaced by the upper low, daytime highs will be about 10-15 degrees cooler to close the week and through most of the long weekend.

That means highs in the 9 to 14 degree range for Thursday-Sunday.

Elsewhere: The cooler air aloft brings in a chance of snow for parts of northern Alberta Friday morning, especially in the northeast corner of the province.
