So is there any evidence to back up CPCs claim this time? Let's take a look.
Below is first off today's forecast highs...HOT for October. Then below we take a look at the highs one the 3 major forecast guidance models we use the Canadian, the GFS-FV3 which is replacing the GFS and the European. Of the 3 I believe the Euro has the better on the overall air mass but the other two cannot be discounted due to building snow pack up north. As you can see though for NEXT weekend, all 3 show generally 50s to 70s for highs Saturday and 60s to 70s for Sunday. The GFS and especially the CMC tend to have a colder bias when it comes to cooler air and even winter. BUT with the lowering sun angle and if we get that snowpack up north to develop then we have the potential to see the highs the CMC advertises. Taking a general blend of these we see temps at to just below average, which fits well with the CPCs outlook for the 6-10 day outlook. The GFS long range does show more of the same but as you know long range guidance changes so much I wont hit on that today.
