Looks like a pattern change is on the way

[snowdog]

Models have been consistently showing a change in pattern coming around next Tuesday or Wednesday.  Looks like a nice push of cooler air coming from Canada.  It will be nice to get out from under this heat dome.

IIRC, the models have been showing a pattern shift that stays about 7-8 days out pretty consistently.  And I don't mean 7-8 days from now, I mean 7-8 days from whenever you look at the models.

Have faith man, this oppressive High has to break down at some point.      

I'm so sick of summer.  This constant heat and humidity is awful.

I'm pretty sure that is taught in Model Mantra 101 during the first phase of the Meteorology program.

Todays 12Z 8-10 day mean show normal heights @ H5.

Well so much for heat relief, models are backing off the cooler air making it this far south.  Dang I hate La Nina!!   

[tennessee storm09]

yeah this la nina is starting to kick and getting stronger. it has a 50 percent chance to be the strongest nina recorded. and it could last well into spring 11. going to get interesting when the northern stream starts to come back south.

Come on, the High has got to break down. Not even the remnents of this tropical system?

[tennessee storm09]

i am affraid its going to take more than a tropical disturbance to break the high pressure ridge down. it will take a strong progressive cold front

This thing is brutal, it may not let the northern stream anywhere near us for the foreseeable future.

Long range 12z Euro is teasing us again with a nice cold front coming down.

This is going to wind up like the snow threads, isn't it? 

[tennessee storm09]

yeah your right toastido. it just keeps getting pushed back further n further.

[Thundersnow]

We're getting closer to when climatology says we start cooling down.  It's getting to be late August now.

[snowdog]

This is going to wind up like the snow threads, isn't it? 

LOL, probably.  It's just fun to watch for the 1st real August cold front to come through.  At this rate though we may be watching till September to get that true 1st cold front. 

The 12z Euro ensembles arent as eager as the op.
