Cool 6-10 Day Period Ahead, But Then What?

A strong cold front will sweep through the area tomorrow and help usher in the coolest air so far this autumn. This will set the tone, combined with the recurving WPAC typhoon, for a chilly upcoming 6-10 day period, but what lies beyond this period later in the month?

Recurving Super Typhoon Hagibis will promote reinforcing chill across our area next week.

We turn to a couple of our more trusted teleconnections for advice.

Note the PNA “bobbing” up and down through the medium range period, with more of a negative look around the 20th. This argues for a milder stretch of weather around that time. (Further out, we’ll keep close eyes on the PNA to see if a more consistent positive signal develops as we inch closer to November).

The EPO pops strongly positive mid month which, too, argues for milder times, locally. That said, similar to the PNA above, the EPO is trending towards a scenario that would present colder times as we rumble towards November. We’ll monitor for consistency.

To no surprise, given the two primary teleconnection drivers above (remember these can change as the seasons evolve), we see the pattern set to turn milder just beyond Day 10. Note the strong agreement between the European, Canadian, and GFS ensemble data below.

Interesting Test Case In Front Of Us: Euro Vs. Everyone Else…

As we look ahead to late September, there’s a battle beginning to take place in model land. When we pull back the curtain, we note the GEFS and EPS handle the evolution of the EPO in two totally different manners in the Week 2 time period.

The GEFS begins to tank the EPO, suggesting cooler times are ahead to close September.
The EPS maintains a positive EPO and associated much warmer pattern to close September.

Our stand on the evolution of the pattern remains unchanged: that much cooler times will return as we get set to wrap up the month and head into early October. Updated data, aside from the European, suggests we’re on the right track with that train of thought.

JMA Weeklies- Week 2

CFSv2- Week 2

GEFS- Week 2

Thursday Morning Rambles: Warmth Continues To Dominate Over The Next 10 Days…

A “cold front” will pass Friday evening. Despite the threat of a couple widely scattered storms this afternoon/ evening, a broken line of storms may accompany the front Friday afternoon and evening. We’re not expecting widespread rain or storm activity with the passage of this front and some yards won’t see a drop of rain over the next couple of days.

A couple of storms may fire up ahead of the frontal boundary Friday afternoon, but widespread rain isn’t expected.
We’ll notice a wind shift from the southwest to west behind the frontal boundary Friday evening.

While somewhat drier air will briefly work into the region Saturday, temperatures will remain well above average. The humidity will return next week.

As we look ahead over next week, generally quiet conditions are anticipated. The big story in the weather department will be the continuation of summer-like heat and an active time of things in the tropics.

Let’s start with the tropics. Guidance overnight has trended further east with the disturbance that at one time appeared it was heading for the Gulf of Mexico. Instead, our East Coast friends should take note of the disturbed weather in the Caribbean. Some model guidance spins this up into a hurricane over the upcoming weekend as it at least “flirts” with the Southeast US coast (perhaps in an eerily similar fashion as Dorian). The item in the open Atlantic is another we’ll have to keep close eyes on for Week 2 for the Gulf of Mexico. Unfortunately, the upper pattern is a favorable one for the Southeast US coastline to experience a landfall over the next couple of weeks…

That same pattern through the next couple of weeks is also one that will continue to produce an “extended summer” across the East.

As we look ahead to next weekend, there’s the potential of a stronger cold front offering up more organized rain/ storm chances followed by a stronger cool shot. We’ll have more on this threat in our Weekly AG/ Severe Weather Outlook published this weekend.
