Hot Arctic and a Chill in the Northeast: What’s Behind the Gloomy Spring Weather?
By Brenda Ekwurzel
When temperatures hit the 80s Fahrenheit in May above latitude 40, sun-seekers hit the parks, lakes, and beaches, and thoughts turn to summer. By contrast, when temperatures lurk in the drizzly 40s and 50s well into flower season, northerners get impatient for summer. But when those 80-degree temperatures visit latitude 64 in Russia, as they just did, and when sleet disrupts Mother's Day weekend in May in Massachusetts, as it just did, thoughts turn to: what is going on here?
Before we jump into the science, let's take a quick look at the unusual spring weather. This past weekend, Russia was the scene of record-high temperatures. A city above the Arctic circle — Arkhangelsk — recorded a high of 84 degrees Fahrenheit on May 11 at the Talagi Airport weather station. The average high temperature for Arkhangelsk this time of year is around 54 degrees Fahrenheit.
Meanwhile in the Northeast U.S., try having a conversation that doesn't loop back to the endlessly gloomy, chilly, unseasonable weather. When gloomy weather becomes such a dominant topic of conversation in a region, a form of citizen science is occurring, and it tells you something: it is unusual, it is anomalous, it is downright wacky.
Many locations are not seeing the sun nearly as much as normal memory serves — and science confirms — for this time of year. The Long Island town of Islip, New York, recorded its longest streak of rainy days on record from April 20 to May 7. It rained for 21 days this April in Boston.
It's not just in the Northeast: repeated rain events resulted in much of the contiguous U.S. being ranked in the 99th percentile for soil moisture on May 14, including many of the Plain states (South Dakota, Nebraska, Kansas, Oklahoma and Texas) and most states eastward. This is a continuation of a high soil moisture ranking percentile pattern (see Jan – April 2019 in Figure 1). Soil moisture ranking percentile is from the 1948-2000 Climatology
As of this writing, there are headlines with exasperated tones wondering when winter will truly depart, including:
- "Chicago narrowly misses breaking 112-year-old record for late-season snow" – April 28, Chicago Tribune
- "It MAY snow in the Northeast this week. In MAY" – May 13, CNN
- "Extreme weather pattern to divide nation next week…"– May 16, Washington Post
In that third article, Jason Samenow describes the abnormal late May forecast for snow, hail, tornadoes, flooding, and excessive heat to different parts of the contiguous US over upcoming days.
Continental U.S. Monthly Soil Moisture ranking percentile for Jan-April 2019. Repeated rain events resulted in a large portion of the contiguous U.S. being ranked in the 99th percentile for soil moisture on May 14.
Unfortunately, the consequences of these gloomy, chilly and rainy or snowy conditions are very real in terms of damages, both personal and in the larger economy. People are taking time away from work — lost labor hours — to deal with them. People are pumping water out of basements and throwing away cherished items lost to water damage.
Some of the flooding is from intense storms like the two rare interior U.S. bomb cyclones that caused flooding and prompted governors to spring into action, calling on the National Guard. There is a current backlog of unmet disaster relief requests. Some of the flooding is from water tables rising since relentless repeated rain events don't allow the soil enough time to dry out.
The natural and human-driven aspects of flooding are critical to tease apart so we can better prepare our communities for the flood risk of today and the changing flood risks of the decades ahead. This is especially important when investing dollars in infrastructure that are anywhere near surface water or groundwater (also known as the water table).
Eurasian October Snow Cover Extent Indicator
It may seem counter-intuitive, but the story of the strange weather unfolding this spring in the U.S. is related in part to snow last October in Eurasia. This indicator — the Eurasian October snow cover extent indicator — is proving to be worthy of additional attention by U.S. weather geeks. The good news is that the scientists who were paying attention to the Eurasia snow extent behavior during October, along with a host of other indicators, gave advanced warning of the emerging U.S. winter and spring weather pattern for 2018/2019. Winter sports enthusiasts rejoiced and sought the snow-peaked slopes of Colorado and Utah.
The bad news is it can feel extremely bouncy going through record-breaking cold and record flooding, with temporary relief periods over these past months. It can feel like riding a seesaw. But the lasting memory of the major pattern is what becomes the talk of the region. Terrific winter snowpack, tragic flooding and gloomy northeast.
You may wonder about the Eurasian snow extent indicator and the broader connections. I encourage those who want to know, to spend some time clicking on the links here or links in earlier blogs that point to even more information (see here, here, here and here). These describe the details regarding how Arctic sea ice decline, particularly in the Barents-Kara sea ice, north of Scandinavia and Russia, contributes to ocean and atmosphere behavior. Which contributes to Eurasian snow cover extent behavior. And ultimately a wavy jet stream with episodic cold outbreaks over winter and spring in the Northern Hemisphere, including the U.S.
Here is an example of the science as Judah Cohen explained, "There is a growing consensus that it is Barents-Kara sea ice in the late fall and early winter that has the greatest impact across Eurasia. Therefore, low Barents-Kara sea ice in November for example, favors a strengthened Siberian high, increased poleward heat flux, a weak stratospheric Polar Vortex and finally a negative Arctic Oscillation. An important point regarding the Siberian high is that it strengthens or expands northwest of the climatological center. For low snow cover and/or high sea ice the opposite occurs." Translation, a weakened polar vortex means more cold outbreaks deep into U.S. territory like this past winter and spring.
We know that burning coal, oil, and gas and the resulting global warming has caused dramatic declines in Arctic summer sea ice extent (minimum occurs in September). It takes longer to cool the warmer than normal Arctic ocean enough to grow new sea ice or thicken remnant ice in the following October and November. Over each successive decade, we are more likely to experience low Barents-Kara sea ice extent over more years, causing weather geeks to keep monitoring jargon indicators: Sea ice extent, Eurasian Snow Cover Extent, Stratospheric Polar Vortex, El Niño Southern Oscillation, North Atlantic Oscillation, Arctic Oscillation and more to improve U.S. seasonal outlooks.
This is little consolation to those throwing out their flood-soaked cherished items from Kansas to Maine this spring season.

1. Stay Informed<p>A first order of business in pet evacuation planning is to understand and be ready for the possible threats in your area. Visit <a href="https://www.ready.gov/be-informed" target="_blank">Ready.gov</a> to learn more about preparing for potential disasters such as floods, hurricanes, and wildfires. Then pay attention to related updates by tuning <a href="http://www.weather.gov/nwr/" target="_blank">NOAA Weather Radio</a> to your local emergency station or using the <a href="https://www.fema.gov/mobile-app" target="_blank">FEMA app</a> to get National Weather Service alerts.</p>
2. Ensure Your Pet is Easily Identifiable<p><span>Household pets, including indoor cats, should wear collars with ID tags that have your mobile phone number. </span><a href="https://www.avma.org/microchipping-animals-faq" target="_blank" rel="noopener noreferrer">Microchipping</a><span> your pets will also improve your chances of reunion should you become separated. Be sure to add an emergency contact for friends or relatives outside your immediate area.</span></p><p>Additionally, use <a href="https://secure.aspca.org/take-action/order-your-pet-safety-pack" target="_blank" rel="noopener noreferrer">'animals inside' door/window stickers</a> to show rescue workers how many pets live there. (If you evacuate with your pets, quickly write "Evacuated" on the sticker so first responders don't waste time searching for them.)</p>
3. Make a Pet Evacuation Plan<p> "No family disaster plan is complete without including your pets and all of your animals," says veterinarian Heather Case in <a href="https://www.youtube.com/watch?v=Q9NRJkFKAm4" target="_blank">a video</a> produced by the American Veterinary Medical Association.</p><p>It's important to determine where to take your pet in the event of an emergency.</p><p>Red Cross shelters and many other emergency shelters allow only service animals. Ask your vet, local animal shelters, and emergency management officials for information on local and regional animal sheltering options.</p><p>For those with access to the rare shelter that allows pets, CDC offers <a href="https://www.cdc.gov/healthypets/emergencies/pets-in-evacuation-centers.html" target="_blank">tips on what to expect</a> there, including potential health risks and hygiene best practices.</p><p>Beyond that, talk with family or friends outside the evacuation area about potentially hosting you and/or your pet if you're comfortable doing so. Search for pet-friendly hotel or boarding options along key evacuation routes.</p><p>If you have exotic pets or a mix of large and small animals, you may need to identify multiple locations to shelter them.</p><p>For other household pets like hamsters, snakes, and fish, the SPCA recommends that if they normally live in a cage, they should be transported in that cage. If the enclosure is too big to transport, however, transfer them to a smaller container temporarily. (More on that <a href="https://www.spcai.org/take-action/emergency-preparedness/evacuation-how-to-be-pet-prepared" target="_blank" rel="noopener noreferrer">here</a>.)</p><p>For any pet, a key step is to establish who in your household will be the point person for gathering up pets and bringing their supplies. Keep in mind that you may not be home when disaster strikes, so come up with a Plan B. For example, you might form a buddy system with neighbors with pets, or coordinate with a trusted pet sitter.</p>
4. Prepare a Pet Evacuation Kit<p>Like the emergency preparedness kit you'd prepare for humans, assemble basic survival items for your pets in a sturdy, easy-to-grab container. Items should include:</p><ul><li>Water, food, and medicine to last a week or two;</li><li>Water, food bowls, and a can opener if packing wet food;</li><li>Litter supplies for cats (a shoebox lined with a plastic bag and litter may work);</li><li>Leashes, harnesses, or vehicle restraints if applicable;</li><li>A <a href="https://www.avma.org/resources/pet-owners/emergencycare/pet-first-aid-supplies-checklist" target="_blank">pet first aid kit</a>;</li><li>A sturdy carrier or crate for each cat or dog. In addition to easing transport, these may serve as your pet's most familiar or safe space in an unfamiliar environment;</li><li>A favorite toy and/or blanket;</li><li>If your pet is prone to anxiety or stress, the American Kennel Club suggests adding <a href="https://www.akc.org/expert-advice/home-living/create-emergency-evacuation-plan-dog/" target="_blank" rel="noopener noreferrer">stress-relieving items</a> like an anxiety vest or calming sprays.</li></ul><p>In the not-unlikely event that you and your pet have to shelter in different places, your kit should also include:</p><ul><li>Detailed information including contact information for you, your vet, and other emergency contacts;</li><li>A list with phone numbers and addresses of potential destinations, including pet-friendly hotels and emergency boarding facilities near your planned evacuation routes, plus friends or relatives in other areas who might be willing to host you or your pet;</li><li>Medical information including vaccine records and a current rabies vaccination tag;</li><li>Feeding notes including portions and sizes in case you need to leave your pet in someone else's care;</li><li>A photo of you and your pet for identification purposes.</li></ul>
5. Be Ready to Evacuate at Any Time<p>It's always wise to be prepared, but stay especially vigilant in high-risk periods during fire or hurricane season. Practice evacuating at different times of day. Make sure your grab-and-go kit is up to date and in a convenient location, and keep leashes and carriers by the exit door. You might even stow a thick pillowcase under your bed for middle-of-the-night, dash-out emergencies when you don't have time to coax an anxious pet into a carrier. If forecasters warn of potential wildfire, a hurricane, or other dangerous conditions, bring outdoor pets inside so you can keep a close eye on them.</p><p>As with any emergency, the key is to be prepared. As the American Kennel Club points out, "If you panic, it will agitate your dog. Therefore, <a href="https://www.akc.org/expert-advice/home-living/create-emergency-evacuation-plan-dog/" target="_blank" rel="noopener noreferrer">pet disaster preparedness</a> will not only reduce your anxiety but will help reduce your pet's anxiety too."</p>
Evacuating Horses and Other Farm Animals<p>The same basic principles apply for evacuating horses and most other livestock. Provide each with some form of identification. Ensure that adequate food, water, and medicine are available. And develop a clear plan on where to go and how to get there.</p><p>Sheltering and transporting farm animals requires careful coordination, from identifying potential shelter space at fairgrounds, racetracks, or pastures, to ensuring enough space is available in vehicles and trailers – not to mention handlers and drivers on hand to support the effort.</p><p>For most farm animals, the Red Cross advises that you consider precautionary evacuation when a threat seems imminent but evacuation orders haven't yet been announced. The American Veterinary Medical Association has <a href="https://www.avma.org/resources/pet-owners/emergencycare/large-animals-and-livestock-disasters" target="_blank">more information</a>.</p>
Bottom Line: If You Need to Evacuate, So Do Your Pets<p>As the Humane Society warns, pets left behind in a disaster can easily be injured, lost, or killed. Plan ahead to make sure you can safely evacuate your entire household – furry members included.</p>

Sweden's reindeer have a problem. In winter, they feed on lichens buried beneath the snow. But the climate crisis is making this difficult. Warmer temperatures mean moisture sometimes falls as rain instead of snow. When the air refreezes, a layer of ice forms between the reindeer and their meal, forcing them to wander further in search of ideal conditions. And sometimes, this means crossing busy roads.
