Raw and chilly day won’t last too long

This certainly is going to be a rather lousy day of weather in May. It won’t be the rain falling as much as those low temperatures which make it feel more like late March and early April. Back in 1917 the temperature was as low as 43F on this day. Another interesting record is for the coldest high temperature set in 1906 when it only hit 48F. Since today’s highs will be in the lower and middle 50s, it’s likely one of the coldest May 28th’s on record.

There won’t be sunshine today, but the end of the day could bring some breaks of sunshine west of Boston. Overnight the clearing will spread east and by morning we are looking at the start of a much better day.


High pressure builds in for Thursday with abundant sunshine. Inland areas will reach the lower 70s with the coast staying in the 60s. This time of year the sun is very strong, as strong as any time of the year, so remember sunscreen if you are going to be outside for an extended period of time.

As we get close to the end of the month I would be curious how you have viewed this May? Have you found it wet or cold, warm or dry? I took at look at the preliminary data through yesterday this morning and was somewhat surprised myself to see we are averaging about 2.5 degrees above the average and have had slightly less rain than average. After last night’s heavy downpours I suspect the rainfall will now be about normal.
One of the reasons it’s going to end up being a warmer than average May is the three days in the 80s from May 10th-12th. Shower activity has been generally consistent with no days of rainfall exceeding an inch. This has meant no spring flooding and reasonably good growing conditions.
As we move past tomorrow’s beautiful day I see the chance for a few showers late in the day Friday. I’m not expecting a lot of rain and most of the Friday late day activities should be able to go off without an issue. I will update the forecast for the rain tomorrow and Friday.
If the weather system that brings the chance of showers Friday keeps moving as expected we will see clearing Saturday and a nice afternoon. Sunday looks like the best day of the weekend. Temperatures will moderate from the 60s on Saturday to the 70s by Sunday. Early next week will continue the trend of milder air with readings well into the 70s and perhaps lower 80s by Monday.
Some of you have asked me about the upcoming summer. With June arriving this weekend and schools letting out in the next 3 weeks many of you are certainly wondering about the summer. Summer patterns are much more difficult to predict than winter, especially since even in the coldest of summers there are still warm days. However, looking at the forecasts models most of them have the northeast in a slightly warmer than average pattern for June.

The problem with these averages is it doesn’t mean we don’t see three weeks of chilly air and one week of very warm air. That doesn’t help you plan for the summer, but it’s the honest truth about summer forecasting. During the summer I will be updating trends and patterns to give you a better sense of what the upcoming weeks look like so stay tuned.
I’ll be updating the forecast @growingwisdom on Twitter.
