Geos Posted April 27, 2014 Author Report Share Posted April 27, 2014 EURO sure disagrees with the CFS regarding the week of the 5th. Model builds a heat ridge in the central part of the country with highs approaching 100° from Kansas to Texas.18z GFS agrees that except for the north Plains the 5th-10th will be very warm in the central US and Southeast. 1 Quote Mercer Island, 350 ft 2021-2022: 11.6", 02/21 2020-2021: 15.6" 2019-2020: ~10" 2018-2019 winter snowfall total: 29.5" 2017-2018: 9.0", 2016-2017: 14.0" Link to comment Share on other sites More sharing options...
Tom Posted April 27, 2014 Report Share Posted April 27, 2014 Ya, I saw that, but I wouldn't be surprised if it corrects itself. Especially when the MJO is going to be in Phase 1 which is a cold phase across the country from the Rockies east. Edit: It also fits with the LRC when we opened March with record breaking cold. Now, those extremes won't happen given the season but it will be May's version of this cycle. Quote Link to comment Share on other sites More sharing options...
Tom Posted April 27, 2014 Report Share Posted April 27, 2014 00z GFS now correcting itself and digging a major trough over the Great Lakes region as the month opens up and what I'm seeing is the model begin to show what could be a nasty set up for some real chilly air for May standards. You can see massive ridging developing over Alaska and a resurging shot of cold air coming down from Canada around the 4th/5th. This fits in line with the LRC when we saw a major arctic outbreak to open up the month of March. Quote Link to comment Share on other sites More sharing options...
Tom Posted April 27, 2014 Report Share Posted April 27, 2014 The EPO/WPO were the main teleconnections that drove our winter season's cold this past winter. I'm wondering if this holds true in May because if it does, this region may be very chilly and stuck in this below normal pattern for quite some time. The AO/NAO are forecasted to stay negative during the 1st week of May. The WPO just falls off the charts... I could see the models doing some quirky things in the coming days as they digest the amount blocking and changes in the atmosphere. Quote Link to comment Share on other sites More sharing options...

Tom Posted April 27, 2014 Report Share Posted April 27, 2014 12z GGEM showing signs of a major cold outbreak for this time of year around the 4th/5th into the Plains, then eastward. GFS hinting at it, but not as deep, most likely will get colder during this time frame. Teleconnections setting the table for some serious below normal temps. Fits the LRC pattern quite well. Let's see if the 12z Euro shows the same. Quote Link to comment Share on other sites More sharing options...
Geos Posted April 28, 2014 Author Report Share Posted April 28, 2014 It can only get so cold in May. Upper 40s is pretty darn cold for highs.Teleconnection influences in May side with the summer regime - and that the teleconnections don't mean as much as they do between November - April. I could see May having some chilly days, especially if you live close to one of the Great Lakes.

Tom Posted April 28, 2014 Report Share Posted April 28, 2014 Sometimes you can get blocking over central Canada in May and especially in the summer months that hooks up and connects with ridging in the Central U.S. Maybe we see that happen late month to bring sustained warmth.

Tom Posted April 28, 2014 Report Share Posted April 28, 2014 CPC 6-10 Day temp outlook....stubborn cold still wants to hang on. I'd take a mental snap shot of this cold pool because the JMA model and the Analogs for the upcoming summer (Jun-Aug) are very similar to the placement of this image.

james1976 Posted April 28, 2014 Report Share Posted April 28, 2014 how long will this pattern last? im concerned that if it holds through the summer that by next fall/winter it will turn mild and dry, leaving us with a lame winter. that would suck!

Tom Posted April 28, 2014 Report Share Posted April 28, 2014 Not necessarily James, we saw this same type of pattern back in 1917/18 1918/19, very similar oceanic water temps in the Pacific with the consistent warm pool of waters in NE Pacific and ENSO regions. I'm not seeing a lame winter next year buddy. Expect a real fast start and moisture laden storms with a very active subtropical jet stream (from the El Nino).

Tom Posted April 29, 2014 Report Share Posted April 29, 2014 Mid May is looking more likely of a pattern flip to above normal conditions for our entire area.

Tom Posted April 29, 2014 Report Share Posted April 29, 2014 12z Euro ensembles on board with a warming trend around the 10th and beyond. This should feel real nice after this miserable week in the Lakes/Midwest. My parents have been visiting Chicago over the past 2 weeks and they have had enough of this weather. So depressing they say... 2 Quote Link to comment Share on other sites More sharing options...

WildWisconsinWeather Posted April 30, 2014 Report Share Posted April 30, 2014 Maybe across the upper Midwest. Things are trending warmer for May now. Next week looks warmer and stormier, at least on the GFS Ensembles. Maybe a nice ring of fire type of setup with parts of the Plains baking with the heat ridge?

Yeah, Accuweather is extremely hit or miss it seems (slightly more often miss), but I think the smart money says their summer forecast this year actually makes decent sense, so I'll give them credit for that. 1 Quote Link to comment Share on other sites More sharing options...

Tom Posted May 2, 2014 Report Share Posted May 2, 2014 I think the models are going to battle amongst each other for week 1-2. The MJO is forecasted to enter Phase 1,2 and 3 which are all cool phases in the east. GFS long range has had very cool runs and some near average. My guess is we see below normal temps in the long range given the pattern we have been in. Next week when temps spike, enjoy it while you can. I'll most likely be baking here in the desert southwest when 100's start popping up. 2 or 3 days of warmth here and there sound like that may be the story this month.
