Phil Posted August 24, 2017 Report Share Posted August 24, 2017 Hopefully we can get a break after the first half of September. We will be looking at basically six weeks of mostly unbroken heat at that point.I'm fairly confident there will be a pattern change when forcing leaves the Pacific, maybe during the second half of September into early October? Hard to extrapolate from here though as the Eurasia/IO area begins the transition out of its monsoonal circulation and into its winter circulation during October every year, which affects the tropical convection/MJO and how it plays on the ET wavetrain.

For instance, the mid-September heat seems to be making an appearance about ten days early. Maybe that will mean the pattern change is earlier than you are anticipating too. I need something right now. 1 Quote Link to comment Share on other sites More sharing options...
Phil Posted August 24, 2017 Report Share Posted August 24, 2017 The dry stretch came to a screeching halt in 1967 with a big storm on 9/2. And October was VERY wet, with over 10" of rain for OLM.I could definitely see strong jet/GOA trough episode sometime during the second half of September or early October. It almost has to happen at some point (IMO, probably when forcing enters the EPAC/leaves the WPAC).

Front Ranger Posted August 24, 2017 Report Share Posted August 24, 2017 That's why I said mostly. Unnecessary flatironing here. Well, "mostly unbroken" was kind of an odd choice of words. Don't take it personal! Most of July was warm but not hot with some coolish days the second half of the month, then there was a lengthy warm/hot stretch the first 10 days of August, then a near normal to coolish stretch mid month, and now it's looking like a hot end to the month.

There was an amazing .09 here in my area from the big storm on 9/1 and 9/2 of 1967. September 1967 was mostly warm and dry out here. October was wet... and November was more decent than usual with more dry days than rainy days.

I need something right now. You have a point there. Harvey also seems to be thermomechanically feeding back on the SW US anticyclone in the recent modeling, so there's that to consider as well. I wonder if there will be two heat spikes (early month and mid-month) before that GOA vortex of doom makes its move later in the month into early October?

Technically we used to live in Escondido although our house was several miles north of the city and about half-way to Temecula. We built our house there in 1998 and sold it in 2003. We had a 12-acre lot in Hidden Meadows. I know Escondido very well.

BLI snowman Posted August 24, 2017 Report Share Posted August 24, 2017 What model shows 48" of rain?? I can't find any location or model showing more than 27" of rainfall over the next 10 days. Those are lower-res models though. They won't ever pick up the extreme amounts from localized convective bands, especially at this range. Given that, the modeled output for TX is extremely concerning. Spots of 35"+ totals appear likely, 40-50" could very well be the higher end. 2 Quote Link to comment Share on other sites More sharing options...

Front Ranger Posted August 24, 2017 Report Share Posted August 24, 2017 Interesting differences in how the Euro is handling Harvey vs GFS. The GFS brings it fully ashore and then it just kind of lingers and peters out (while dumping copious rainfall), while the Euro has it hugging the coast and remaining a much more intense storm as it slowly drifts NE. Hard to say which scenario would be worse overall. Quote A forum for the end of the world. Link to comment Share on other sites More sharing options...

Spots of 35"+ totals appear likely, 40-50" could very well be the higher end. ECMWF does pretty well usually but yeah you never know with convective banding. Hi-res 3km NAM has even less precip over the next 84 hours FWIW. I have a REALLY hard time believing anyone will see 40"+ out of this IMO. Definitely a few areas will see 30"+ but I just think 4ft of rain is a bit dramatic and unrealistic based off of current guidance. Either way, it's going to be a devastating storm and I'm sure we'll be hearing a lot about Harvey over the coming days.
