Tom Posted August 24, 2020 Report Share Posted August 24, 2020 Folks, we just about made it through one of the warmest Summers in recent memory. I believe many of us experienced a Top 5 Summer in terms of warmth. Phew, thank goodness its almost over! Do you agree??? Well, to those who have waited patiently (myself included)...does nature have a pleasant gift in return??? It appears almost likely that we will welcome the first month of met Autumn with a major shift in the overall weather pattern in a timely fashion. Let's discuss.... From what has been a hot and dry August, it will more than likely turn very active, cool and wet for a majority of our Sub. The latest 12z EPS is suggesting several strong CF's to traverse the Sub, each one delivering rounds of possible strong/severe storms along with penetrating the cooler air very far south. We have not seen such a pattern during the opening days/weeks of September in a long time. Check out the latest maps off the 12z EPS... 3 Quote Link to comment Share on other sites More sharing options...
Minny_Weather Posted August 24, 2020 Report Share Posted August 24, 2020 Continuing from Tom's post, the EPS weeklies are encouraging. How long has it been since we've had a September without a dumb heat wave in the middle to end of the month? We may not have one of those this year. Just near-normal. 2 Quote Formerly *ahem*: LNK_Weather, TOL_Weather, FAR_Weather, MSP_Weather, IMoveALot_Weather. Link to comment Share on other sites More sharing options...

Tom Posted August 27, 2020 Author Report Share Posted August 27, 2020 Last night's JMA weeklies continue to advertise a cool month ahead and trending cooler for Week 2 into Week 3-4. I like the looks of an active W PAC that seemingly may come alive after a record low ACE thus far. Week 2... Week 3-4... The W PAC comes alive Week 2 and really amps up beyond that period.... Looking at the 500mb pattern towards the end of the month, the ridge placements off both coasts of North America continue to be a theme. Let's see if this holds because these blocks could be interesting semi permanent features going forward. I see you Hudson Bay Vortex! 1 Quote Link to comment Share on other sites More sharing options...
OKwx2k4 Posted August 27, 2020 Report Share Posted August 27, 2020 The record Atlantic season so far has stolen the show. That PAC is going to kick off right at the proper time.

Minny_Weather Posted August 27, 2020 Report Share Posted August 27, 2020 EPS keeps most of the sub cold through the extended.

Tom Posted August 28, 2020 Author Report Share Posted August 28, 2020 00z EPS and recent op runs off the GFS in the extended, along with the CFSv2 are all advertising the seasons strongest and most potent CF right around Labor Day and thereafter. This could really bring the "Autumn Chill" to parts of the central/eastern Sub. Again, the theme seems to revolve on a western US ridge and eastern CONUS trough along with High Lat Blocking...the 30-day map is the recent Euro Weeklies run which doesn't show any sustained warmth, maybe at times in the high plains but generally speaking, it parks a long-term/long wave trough over the central and eastern CONUS. 3 Quote Link to comment Share on other sites More sharing options...
Tom Posted August 28, 2020 Author Report Share Posted August 28, 2020 After digesting the Euro weeklies farther, for the most part, the teleconnections setting up argue for a wavy and amplified jet stream that will have no problem ushering in cool to cold air out of Canada. -AO/-EPO/+PNA/-WPO....we haven't seen these readings all line up before since I believe the '13-'15 seasons. You start to wonder if nature is setting up a long term long wave pattern up in the northern latitudes. Speaking of this, using the BSR as guidance, nearly all of the LR models show an Aleutian trough/NE PAC ridge. If this were to hold, we would take this as guidance and begin to paint a picture on how October will open. Take a look at all these various models and come to your own conclusions... 3 Quote Link to comment Share on other sites More sharing options...
Tom Posted August 28, 2020 Author Report Share Posted August 28, 2020 To add farther to my post above, a powerful Bearing Sea/Aleutian Low will explode today through the weekend...extrapolate this period 17-21 days out, we could be seeing a monster trough across our Sub mid month. 1 Quote Link to comment Share on other sites More sharing options...
Iowawx Posted August 28, 2020 Report Share Posted August 28, 2020 August is going to finish well below normal for rainfall here. How do rain prospects look for Iowa as we head into September? Some parts of Iowa are in an EXTREME drought, and I hope that the drought doesn't get any worse around here. 1 Quote Link to comment Share on other sites More sharing options...
snowstorm83 Posted August 28, 2020 Report Share Posted August 28, 2020 According to the 16 day 12z GFS, today will be the last day in the 90s here. Probably won't happen, but I'm simping over it right now. Unfortunately, I'm not super impressed with the rain chances early next week. It's on the downtrend and seems like something that can fall apart easily.

Tom Posted August 28, 2020 Author Report Share Posted August 28, 2020 I mean, these maps speak for itself...just classic high lat blocking along with monster ridges off both N.

Maybe I can pull up an old map and compare to where the model is going now.
