Seasonable…Wet At Times. 4/22/19
Hello! Happy Easter to all who celebrated! I hope everyone enjoyed their, weekend! While Saturday was wet at times, the complete washout that was anticipated, never really materialized. Though for sure, it was just enough rain to foul up outdoor events & activities.
Easter Sunday began on the damp side, but the sun broke through around the Boston area as anticipated, boosting temperatures up to near 70 degrees in the afternoon. All in all, not a bad Easter Sunday for all to enjoy!
After a chilly start, April has warmed up nicely across the Boston area. In fact, we are now running 4 degrees above the average for the month. This is in stark contrast to the 4 degrees below average last April!
As expected, the warm temperatures has prompted green up across the region. The first thing you may have noticed is the grass turning green. What a welcome sight after a long, grey winter!
The second thing you may of noticed is the sudden blooms of forsythia and magnolia trees. With all the rain we’ve had, the spring colors are vivid this year!
Finally, with temperatures so warm, the trees have actually begun to bloom. What was one week behind schedule, has suddenly turned into one week ahead of schedule! This is what above average temperatures will do for spring blossoms at this time of the year!
While this week looks to be on the mild side, there is no very warm weather anticipated for the rest of the month. However at this point, I don’t see any change in timing for leaf out across our area. Expect most leaves to be out in Boston by early May, and full leaf out by our average date of May 10th.
Though we have transitional seasons of spring and fall, I like to look at our climate as a 50/50 proposition. Staring May 1st is our “warm” season, which means leaves on the trees, lawn mowing, flowers and gardening. This runs to October 31st, which is a full 6 months.
We then have our “cold” season, which runs from November 1st, to April 30th, which includes winter, which runs from December through March.
There are many ways to interpret the climate, this is just one way I like to look at it around here. Of course we have spring and fall, which may be longer or shorter, depending upon the year.
You would think that we would be completely done with snow in Boston this time of the year. But this was not the case back on April 28th, 1987! On this date, Boston was hit by a slow moving late season nor’easter!
I remember that April being cold and wet. The kicker was the unseasonable snowstorm at the end of the month. While Logan Airport recorded a record 4.3″ of snow for so late in the season, many surrounding communities received between 6 and 12″ of heavy wet snow.
Further inland and in the hilly terrain, between 1 and 2 ft of snow was common! I remember leftover snowbanks lingering into the first few days of May!
I don’t anticipate any unseasonable late season snowstorms this year. The latest snow ever recorded in Boston was on May 9th, 1977, in the historic Mother’s Day snowstorm! So you never know for sure, until after that date!
I recently chatted with my friend Remy, who is a Atmospheric Science major at Cornell University, about our current weather patterns. we both agreed that the pattern has been warmer than average along the east coast, including New England, since last May.
In fact, the only below average month since last April, was last November. Every other month has since then has featured above average temperatures. Looking at the long range guidance, most data is indicating a continuation of warmer than normal weather through next fall, at least!
So this leads me to my summer preview. Based on trends, the early call for this summer is a warmer than normal summer on the way, for most of New England. Computer models are showing hotter than normal.
This is not my final call. I’m strictly going on what computer models are projecting, and we all know how that worked out on their call for a historic winter along the east coast this past year!!!! Answer…not good!
After last years much warmer to hotter than normal summer in Boston, which featured 23 days when the temperature eclipsed 90 degrees or higher, I find this outlook hard to believe.
Why? Well the average number of 90 degree days in Boston for a typical season is 14. I don’t believe the city has ever recorded two back to back summers with 20 or more 90 degree days in the history of record keeping.
I’m not saying it can’t happen. It seems as if we’ve entered a new era in our climate, where anything and everything can happen. Typically, it’s been warm weather records being broken in recent years.
If we do eclipse 90 degrees 20 times or more this summer in Boston, I would be shocked. I would even go as far as to possibly change my mind regarding the mounting evidence of a warmer climate regime here in Boston.
I’m still holding out hope that this warm period is a cycle, mainly due to the much warmer than normal ocean temperatures being recorded across the world.
I’m actually very excited to see how Mother Nature responds to our climate this summer. Will she go against what computer models are projecting, and somehow drive cooler air masses in from Canada to keep it close to normal here in New England?
Or, will the heat simply overwhelm the eastern part of the U.S. and we broil once again with either similar or even hotter weather than last summer? My final call for this summer will be posted on May 27th, only about a month away!
Now for your weekly outdoor spring activity forecast. I will rate this week a 5 out of 10. Somewhat unsettled, but still mild.
Expect a washout for the rest of today! Showers moving in, heavy at times, with the chance of a rumble of thunder towards evening. This is in stark contrast to the sunny and warm morning we experienced.
Rain will continue the first part of the night, then gradually come to an end overnight. It will be damp and cool, but not cold. Watch for areas of dense fog after the rain diminishes.
After a murky start, Tuesday should feature brightening skies during the afternoon. Temperatures should respond into the lower 60’s.
There may be another round of showers tomorrow night, which should end by early Wednesday morning. If we get enough sunshine later Wednesday, and I’m planning on it, temperatures should warm up to near 70.
No rain is anticipated for Wednesday night and Thursday. Lows should only drop into the 50’s Wednesday night, and warm back up into the 60’s on Thursday, with possible sea breezes keeping it cooler along the coast.
While Friday may start dry, another fast moving storm will be approaching New England from the southwest. This will bring increasing clouds during the day, with rain arriving towards evening, and lasting into the first half of Saturday.
Right now, if timing works out, this system should clear the coast so that Sunday would be the better of the two weekend days, with mainly sunny skies, and temperatures in the upper 60’s, or even low 70’s.
Well, that’s about it for now! In next week’s blog, I will have my April review, and May preview! Hard to believe how fast time is going! I will also let you know if I have any new information regarding our summer forecast! In the meantime, seasonable is nice this time of year, if we could just get rid of this darn, rain!
Thanks for reading!

Happy Easter to all Eastern Orthodox Christians, this Sunday!
