Wow close month this go around

Someone had posted this in another thread to give you perspective on how things have changed and will once we go to the new 30 year climo.

Little update I believe we measured the greenland high around 1065mb give or take a few mbs just south over the ocean had a slp of 1040s so seems reasonable with the potential of higher over the ice sheet. Always hard to know with a large portion of that region being 10-13k feet above sea level, so you know extrapolation. Still have quite the fram export event taking place as the low moves into the Central Arctic regions. Looks as though there may be a day or two of slowing down on export but man it looks like it picks right back up in mid to long range. Really hope this is not a sign of a major ice depletion situation. With such strong export Ice is reaching Iceland, this happens from time to time but I dont recall it being the case this time of year. Again maybe the one nice thing is we aren't exporting some of the multi year ice that is left, what little there still is. Very worrisome of what may come this summer.

Thats pretty crazy to me. I dont think I have seen pressures higher than maybe mid 1060's mb around Greenland so if even the 1070-1080mb range verifies this may very well be a record, unfortunately my search has come up empty on the highest pressure reading from a station on Greenland's ice sheet unless others may know. I just noticed the map I posted of ice thickness ended at the last day of February so here is hycoms depiction of the last 30 days fairly similar to AMSR where the highest values are but there are some differences that stick out such along the CAA and siberian sea region so it will be interesting to see which is closest to reality. Still both show issues on the Atlantic front to the north pole so they both seem to agree at least on that front. I guess the one positive, if you really wanna call it that, is the lack of multi year thick ice what is left of it isn't being exported into the Atlantic to melt off. Ill have to see if I can find a multi year ice gif to show where we have the remaining portions of it and what is rather new thin ice.

So this is interesting. Fram Strait export picking up with such an anomalous high pressure system with a countering LP just east. Yes 1089mb high forecasted over Greenland in a little over 3 days. We have had such large high pressure systems this year, earlier around Mongolia if I remember correctly back in December I dont believe broke the record there but was awfully close. Impressive stuff this year. I worry about the ice on the Atlantic front to near the north pole especially this year with how low thickness values are to the norm. Edit it actually beat the world record https://www.independent.co.uk/news/uk/home-news/world-record-high-air-pressure-mongolia-b1780381.html

Is there a specific reason you are showing these?

Are we switching to 1991-2020 averages and then retroactively changing past months when it comes out (whenever it fully is done being implemented) or finishing the year with our 1981-2010 baseline?

wooof competely missed that deadline lol DCA: +3.1 NYC +2.3 BOS: +1.8 ORD: +2.6 ATL: +3.2 IAH: +3.4 DEN: +1.8 PHX: +2.2 SEA: -0.5

I like the enthusiasm but if im struggling to get more than flakes down here I dont see how this would push much more north the only thing we are hoping for is a close to the coast start up but that floods a lot of areas along the coast with warmth until it bombs and flips it for locals. Track has been fairly solid with this one for the past ~2 days

Welcome to the weather we deal with all the time down this way. I have gotten use to it regardless whether we get snow or not I still like to talk about these patterns. Feel it might be a situation that you may be expecting something more then should be perceived. I like coming in here to see what the talk is and get some met obs since my area lacks a little of that. I try not to hold onto them much when I see a pattern that can be exciting Id rather track the systems then get blasted with snow cause then I have to clean it up and there isnt much place to put snows in the city, but dont get me wrong snow is fun!

I know its a hop, skip, jump down to my area but working at KBWI we had 57 on the second, that was a really warm day felt like a taste of spring. Yesterday hit a high that just scraped 50 but most have been low to mid 40's about 2-3 degrees above average. The nighttime lows though... last 2 days have been the closest to average but most have been mid 30's even some upper 30's that is almost 10-12 degrees (if not more on some days) above average.

The nighttime lows are whats killing it. Even down this way the daily highs really haven't been that warm but the overnight lows which would normally be in the low 20's even some teens just north of me are sitting in the low 30's, with that stretch of clouds at the beginning we had a 5 degree swing with lows in the mid 30's that roasts averages.

They also have such a better cold resource than we do unfortunately.

Lol wayyy too much but hey it may happen again one of these years. Thats going to be one rough melting season over there.

Wow! I love snow and all but man waste high snow ill leave to them. 2008-09 winter down here was nuts! It looked like that in many places and I was good on not having snow for quite some time. Seems like I got my wish for the most part lol To give reference to this video in the explanation section they say 10 feet of snow on the ground in Hijiori and in Takada they received 6 feet of snow in 72 hours. Now im very unfamiliar with Japan but this is wild to hear.

I like the setup potential but am really curious as well how this sets up. I would almost argue it may have more of a positive tilt to it with the extended ridging potential with such warm SSTs in the Atlantic. I wouldnt call it a progressive at all, just really hope suppression doesnt become a thing, but overall just really interested what this setup will yield. Great write up though! Whatever is coming sure does look fun though.

That is a huge worry of mine as well but great write up. The possibilities with this could very interesting! Excited to see how the next 2 weeks unfolds.

Current Obs of KBWI: Quite windy over here right now having 13 knots gusts to 20knots out of the ENE Temp 32/19 Was chatting with a met from OPC and we both were in agreement this is the beginning portion of the arctic air. Would really like to see that dew point drop to the low teens say 12-13F to show the depth of the cold pool. Line sits around AVP/Allentown/ to just south of NYC with that nose of arctic air. Low temps and matching low dew points, single digits. Lets have some fun nowcasting today can't wait to just see how it all unfolds regardless of what I get back at home in the Lancaster area.

I would like to take a better look at the skew T's for this but wanna wait until maybe 00z tonight to see if everything is going to hold. So far the 12z runs have held steady and come more in line with each other.

If I still worked there I could tell you. I actually was supposed to work that shift but called my boss to tell him that morning there was already 5" of snow on the ground lol. Next day couldnt go in either because they couldnt plow the streets. Took them 2 days to get the city back to normal, lancaster that is and they got more NW of us. I would be impressed if we see more than 12:1 during the height of the storm for areas around harrisburg. Most should see the average 10:1 and then maybe getting better as the colder air continues to filter in. I say maybe 14:1 on the outskirts to help with totals otherwise more than that is not impossible but probably unlikely.

Hey thats awesome, I went to Millersville as well for my Met degree. During my time there was one student who had gone into minoring in Space weather, Mike something. I do not unfortunately know where his path has taken him other than he went onto graduate school to broaden his understanding of space weather; I believe he was in talks with the folks out in boulder, CO during the one space weather outings the class had taken. Yea study hard try to get into internship opportunities or research excursions to help give you a foot into something you may want to do. DeCaria was a tough one to deal with in thermodynamics but he usually does what he can to work with you. Sikora was my advisor and an awesome forecasting teacher he had helped me land a job coming out of school, not exactly where I was hoping but it essentially helped me get a foot in the door and meet new people that could help me in the long run. Stay strong push through and have fun with it was truly some good times going to Millersville.
