April Showers…Bring May Flowers! 4/26/21
Hello! I hope everyone enjoyed their weekend! In terms of weather, it was a 50/50 weekend around our region. Saturday was nearly perfect, with sunny skies, light winds, and temperatures in the low to mid 70’s. A weak coastal low brought cooler weather on Sunday, with a period of rain which was heaviest south of Boston, especially in the morning. Conditions dried out during the afternoon, but remained cloudy across most of the area.
Yes, I believe I have used this same title in a previous post in the past! I assure you, I did not copy and paste! It just seems appropriate with the expected showers of this week, and the arrival of May coming up this Saturday, that I repeat this old saying! Although, with the warmer than normal April this year, it appears the flowers of May have already arrived!
Good news and bad news. The good news was that the storm I forecasted from last Monday was much weaker than anticipated. The bad news is that we really could of used a good soaking in Boston, and especially points north into New Hampshire. Boston continues to run a rainfall deficit of nearly 4″ for the year, so far.
This number in itself is not any reason to panic. However, we are just coming off a fairly extreme drought for our region last year. We had some decent precipitation over the winter, but not enough to give a surpluss of water. The concern is that we are about to enter the drier summer months, running a precipitation deficit, once again.
It’s difficult to say what kind of a summer we’re going to have, in regards to rainfall. Last summer was just awful. Overall, it was a very dry summer, with iradic areas of precipitation. Some places received deluges of torrential rainfall, while others missed out. Overall, it was a very dry summer across most of New England, with large portions of the area under extreme drought warnings.
If we do not receive ample amounts of rain in May, this could easily come back. The good news is that there’s still time for changes. May can be a very wet month, and so can June for that matter. A few good soakings could easily erase any deficit we have.
It’s still early. May is still considered a transition month. Leftover cool air masses from winter can interact with building heat in the south, creating large slow moving rainstorms. This could be our last chance of seeing widespread rainfall associated with seasonal low pressure systems, even nor’easter type storms, until later next fall.
Yes, nor’easters can still occur in May. Snowfall is also still possible across the higher terrain during May. History tells us of major snowstorms occurring in the White and Green Mountains of New England do occur some years. Just last year many had accumulating snow as late as May 9th across New England.
Officially, we can end the snow season in the Boston area after May 10th. It’s very rare to see snow this time of the year, but it’s not entirely out of the question. It has happened several times in the past, as I will explain in my segment of weather history shortly!
As the jet stream begins to retreat up into Canada, the summer patterns begin to emerge across the country. This typically begins in earnest around Memorial Day in New England. At that point, we begin to rely on frontal passages for precipitation through the summer months of June through September. Depending upon the patterns, these frontal passages can bring copious rainfall, or just hit and miss “garden” variety afternoon storms.
Looking at some of the long range computer models, they continue to show a warmer than normal summer coming up for us this year. It’s still a little too early to place numbers on this just yet, as I base how hot the summer is with how many 90 degree days we receive from the period of May through September.
Last summer was a deceivingly hot summer. Statistically, Boston’s logan airport reached 90 degrees 14 times over the course of the summer, which happens to be exactly average. However, very weak, feeble seabreezes prevented many more 90 degree days from occurring.
In fact, Boston had at least a half dozen days, if not more, of high temperatures of 89 degrees at the airport. This means many locations just inland surrounding Boston received between 20 and 30 days of 90 degree days last summer, making it a very hot summer indeed!
It was also a very dry summer! As mentioned above, there were some communities that received some drenching downpours. However, this was the exception, not the rule, as many towns were left high and dry the entire summer into the fall.
It’s hard to believe we will see another summer like that repeat itself. With that being said, nothing can be taken off the table. It appears we are in a cycle of hot and dry summers, & mild and wet winters, the way I’m seeing things.
It’s a double edged sword. Many people, if not all of us enjoy nice summer weather for outdoor activities, most especially on cherished weekends. However, our environment needs the rainfall to replenish our ecosystem, reservoirs for drinking water, and to feed our trees and vegetation. Farmers and gardeners most appreciate plentiful rainfall to grow healthy crops and to maintain lush gardens.
Whatever happens, we are not in control of it! Mother Nature has it already figured out. There’s a reason for drought and floods. It prevents disease, keeps pests at bay, and replenishes life. My official summer forecast will be posted on May 24th this year. Stay tuned!
With it being the last week of April, it’s pretty safe to say winter is over in Boston. As mentioned above, there have been rare exceptions! Overall, I was very pleased with my winter forecast this year! This coming off two disasterous winters.
Back last November, I forecasted a volatile winter, with periods of stormy, cold weather punctuated by stretches of mild, tranquil weather. This actually worked out quite well! I was calling for between 30 and 40″ of snow in Boston back in November. I bumped that up to between 40 and 50″ at my winter solstice update. This wasn’t a bad move, as most of the area in and around Boston received just that, if not a touch more. Officially Boston’s Logan airport recorded 38.6″ of snow this winter. This is about 6″ below average. Being right on the water, Logan typically receives less snow than surrounding areas.
However, with this being another La Niña winter, interior locations received more snow than the coast. Therefore, many communities received much more snow than at Logan airport. As is typical, some locations were actually above normal this winter thanks to a big mid December snowstorm and a snowy February. Metro west Boston seemed to be in a jackpot zone this winter, with several heavy snowstorms.
Worcester, Ma., for example, received a whopping 77.7″ of snow, which is about 13″ above normal. I measured 48.5″ of snow here where I live in West Roxbury section of Boston, which is about exactly average for my area in a typical season.
Don’t forget, we began the snow season way back on the pre Halloween record snowstorm last year on October 30 th, where the Boston area received 4 to 6″ of snow! What a scene that was!
The one downside was the call for a bonanza winter for northern New England. Other than a big mid December snowstorm, many locations finished either at or below normal snow, which is very unusual for a La Niña winter. With that being said, ski resorts enjoyed a solid winter, with very few, if any major meltdowns.
Overall, the call for a mainly below average snow (mainly along the coast), but snowier than last winter, worked out quite well this year! Overall grade: B+ !!
Before I get to our forecast, I wanted to write a quick segment of weather history! Back on April 28th 1987, the Boston area witnessed a very unusual weather event. A very late season nor’easter brought record breaking snowfall to our region, including the coast! Logan airport reported a record 4″ of snow, while surrounding communities saw between 6 and 8″. This was just in Boston. Suburban towns received between 10 and 18″ of wet snow, with even more across higher terrain of Worcester county, where some areas measured 2 ft! It was the grand finale to a very cold & stormy April that year.
Now for your weekly outdoor spring activity forecast. I will rate this week a 7 out of 10.
Expect mainly sunny weather for the rest of this afternoon. There will be a gusty wind at times which will make it feel quite cool for this time of the year. Don’t let that deter you from taking a late afternoon or evening walk. Just put a jacket on and you’ll be fine.
Watch for clear and cool weather for the first part of tonight. As you’re taking your evening walk, don’t forget to check out the rising full “Pink Moon” in the eastern sky! Native Americans named it this moon due to the abundant pink wildflowers that bloom this time of the year. It will be cool with lows in the 30’s and 40’s. Clouds will tend to increase later on at night.
Tuesday will feature a mix of sun and clouds. It will be noticeably warmer, with highs in the 60’s and low 70’s. There may be a few showers Tuesday night into Wednesday morning, but a widespread rain is not anticipated.
Wednesday may start cloudy and slightly damp, but conditions should improve during the day, with breaks of sun and mild temperatures, with highs in the 60’s to possibly near 70. However, watch for building clouds during the afternoon, with the chance of showers developing across the area during late afternoon and evening.
Here come those April showers for both Thursday and Friday! It will not be raining all the time, but a wavy front will mean periods of showers and damp weather from time to time. Timing is too difficult to pinpoint, but expect some much needed rainfall. Light onshore winds could keep temperatures in the 50’s along the coast, but 60’s across the interior.
Happy May Day! Happy May 1st! A strong cold front looks to sweep this inclement weather off the coast early Saturday. This means Saturday should feature breezy conditions under partly sunny skies, with temperatures between 55 and 60, somewhat like today. Though a brief shower can’t be ruled out.
For those who celebrate Eastern Orthodox Easter this Sunday…plan for a splendid early May day! Expect mainly sunny skies, lighter winds, along with warmer temperatures, with highs reaching the mid 60’s across the region. I promised my friend I would work on a nice day for her & her mom…I hope this works out!
Well, that’s about it for now, friends! In next week’s blog, I will have a review for April, and look towards what May will have in store for us. I will also continue to look into our upcoming summer weather patterns. I will also have a new camping and hiking forecast, as well as a pollen outlook. In the meantime, pray for those April showers, so we can keep the pollen levels down, and enjoy those May flowers!
Thanks for reading!
Happy Easter to all Eastern Orthodox friends & family!
