Just imagine these departures in July, 2010 was way up there but +5 to +7 would be ridiculous.

Well likely settle down around +3 to +4 for the month. Best normal right through Friday with warming by Sunday and Memorial Day.

The continued heavy rainfall potential over Texas and Oklahoma may lower

our 95+ heat chances going into June since it's often a source region

for major heat here. The Euro weeklies have a warmer than normal but

not particularly hot looking pattern from the end of May into June.

Will be interesting - in 2013 the WAR retrograding west and hooking with the rockies  ridge did the trick.  2010, 11, 12 the heat source from the then mid west/plains drought.  1993 was very wet in the mid section but not so much in Tex/ok.

Yeah, it will be interesting to see. The current round of long range models  into June never really let the WAR build back far 

enough to tap warmer temps further west. The persistent low pressure with the trough and rains over the Southern Plains 

seems to get in the way of this process.

I'm back after being banned for a week. I love this weather finally got some much needed rain. Watch for some heavy rain tomorrow morning possibly severe thunderstorms. Than a whole 5 days of beautiful weather enjoy it everyone!

Edit: there are some nasty thunderstorms developing possibly reaching severe level just west of New Jersey. Let's see how far east they make it. Thinking is they are developing there because the sun is out and here we have cloudy skies so I doubt they make it here unless this fog/clouds burn off! Should be fun tracking them today!e5370878090775b7e599482f7ea1d28f.jpg2a18b2744c647262feaa953421d0ec45.jpg

We also have a big -EPO/AK ridge pattern which keeps the Hudson Bay vortex far enough south to mute the SE ridge...you see this the most in the GFS forecast where heights are just average here despite a ridge to the south because we have a strong ULL to the north over Quebec/Hudson Bay.

That activity is well forecasted to hit the brick wall known as the backdoor cold front and stall too far West.

That big -EPO spike probably means that portions of the interior Northeast could see a frost or maybe

a freeze Saturday later this week into Saturday.

I was just mentioning in the New England thread that our vacation house in extreme NE Pennsylvania may see a frost on Saturday morning. It's at 1560' in a lake valley, surrounding by ridges in the 1800-1900' range..highest peaks are like 2400'. They had a frost during the last cold shot, and am expecting one this time around...Thicknesses approach 534dam with 850s of 0C and potent high pressure overhead. The forecast low is 37F at this moment, but with models showing a stronger reinforcing cold shot on Friday evening after the initial cold air advection tomorrow night, I expect the actual low for Lake Como PA to be 33-34F...

 

Dobbs Ferry has a projected low of 51F on Saturday morning with the only 40s on Thursday morning. I'm actually expecting Saturday to be a bit chiller than Thursday around here as well...should get down top 46-48F.

The key may be the arrival of the high pressure center coinciding with the Saturday morning lows. There could be

some impressive radiational cooling should the winds go calm. The Euro and DGEX aren't as bullish as the

GFS is so we'll see how it goes when we get closer.

12z ECM does push the 0C 850 contour south of here, but briefly.

I use a neighboring station. But i dont think 89 was an actual high here maybe 85 give or take.

Yeah if your using weather underground, you have to weed out some of the bad stations...unfortunately there are more and more poorly designed and improperly sited stations coming online there.

Yeah i've noticed. There's one in LIC that's especially bad. Sometimes its 10 12 degrees warmer than surrounding stationS and I'm like there's no way.
