"By early Friday morning the flow
aloft will change southwesterly as longwave trough digs into the
Rockies and Intermountain West. Lee cyclogenesis is forecast in
the Northern Plains Thursday night. The low pressure system will
likely lift toward the northeast into the southeastern Canadian
Prairies and northwest Ontario by Saturday morning. Deterministic
and ensemble models differ in the details, but seem to have good
agreement in the placement of the trough and eventual eastward
progression. Southwesterly return flow is possible ahead of the
system, which may support strong to severe thunderstorms Friday
afternoon and evening and perhaps again Saturday.

Temperatures will remain near to below normal for the long term
period with afternoon highs in the middle 60s to middle 70s and
overnight lows in the 40s and low 50s.

I made reference to this a month or so ago, but as I watch another short wave dig through the SW like it's March (with yet another this weekend), it's looking more and more like our sub-tropical high isn't going to set up shop in the four corners any time soon. We're "technically" in monsoon season now, although it really doesn't get here till around the 4th of July, but if this long term pattern doesn't change soon, it could be a very miserable, dry summer down here.  :sad:

Up in Page, you could set the calendar with first thunderstorms breaking out and independence day and never be off by more than 1 or 2 days.
I thought it was assinine when they decided to set an artificial monsoon date mid-June usually the driest and hottest time of year. Maybe once a decade it starts that early, they should go back to the 3 dewpoint days in a row over 55 for Phoenix as the official start.

It was done to appease non locals so they'd have an "idea" when the t-storm season might start. I though it was/is stupid as well. Here we use, well use to use, a 3 day average of a 54F dew to signal the start of the monsoon. Why PHX uses 55F, dunno.
