The heat streak continues for the Capital Region, Central & Southern Albera and Eastern Alberta.
Daytime highs in all those regions will be near 30 once again.
But...a cold front will slowly approach from the west bringing gusty wind & a risk of showers and thunderstorms.
In W & NW Alberta, the slightly cooler air will hold daytime highs closer to 20 in areas like Grande Prairie.
Wildfire Alberta is forecasting an "EXTREME" fire danger for much of Northern & North-Central Alberta today.
So, the risk of lightning will be a concern in areas near Edson/Whitecourt this afternoon.
That risk pushes closer to the Capital Region this evening & there's a chance of some showers and possibly a thunderstorm in the Edmonton area this evening.
In Fort McMurray, temperature hit 33 & the Relative Humidity was 13% on Tuesday.
Today looks very similar. Temperature will get to 30 or higher again & RH is expected to be in that 15% range this afternoon.
That's the "crossover" conditions that wildfire forecasters get some concerned about (when the temperature is higher than the RH).
Wind will also be a problem. It's forecast to increase to W 20 this afternoon (with some gusts).
As the cold front goes through, gusts could be in the 50km/h range this evening & the wind direction will change to NW.
We though there MIGHT be a bit of precipitation in the area along that cold front.
But, the latest model output keeps the area dry (with a chance of scattered showers or thunderstorms south, closer to Cold Lake) Fort McMurray is expected to cool to a high near 20 Thu. Fri should be back to the low to mid 20s.
Saturday could be a return to near 30-degree heat in that area.
Next chance of rain? Sunday evening/Monday.
In the Capital Region - Hot today with a risk of scattered showers and/or a thunderstorm in the area this evening.
Cloudier & "cooler" Thursday (although the forecast high will still be above average).
Back to the low-to-mid 20s Fri/Sat/Sun with a chance of rain Sunday night/Monday.
