DAYS 1-5 (APRIL 25-29)
The spring of 2025 rolls on and is starting to gain a bit of a reputation for being “not that nice”. Now this is only partially true, as it’s a matter of perspective and what amount of time you’re looking at. March was a rather dry and mild month, but with many people still in “winter mode” they don’t partake in the springtime activities outside, which explode in popularity in the month of April, especially around here when we approach and reach the weekend that includes Patriots Day (just this past week). But even before that, the “hibernating” folks come out for their first walks, yard work, etc., and like to be greeted with some good weather. And don’t get me wrong, we’ve had some nice days, but the timing of the unsettled days has been including at least parts of weekends much of this month, and the final weekend of April 2025 is going to be no different. Ouch! It’s not a total wash-out, but the weekend is not going to get high marks from the average person. How will it unfold? First, we have a warm front pushing through the region now, and abundant clouds are in the sky. This will be the case much of today, but there will be some intervals of sunshine as well. I can’t rule out a few rain showers migrating across the region, particularly over northern MA and southern NH. The frontal boundary also comes to a halt and may slip back to the south as a “temporary” back-door cold front, shutting the NH Seacoast and northeastern MA out of the warmer air with a light northeasterly air flow. Meanwhile, the south to southwest wind that overtakes the remainder of the region is naturally a cooler one for the South Coast and Cape Cod at this time of year, so they’ll be in much the same boat, temperature-wise, as southeastern NH and northeastern MA is today. During the weekend, we start with a fairly mild but unsettled Saturday as a trough and cold front have to move through, and won’t be in a grand hurry. Timing-wise, it looks like the most widespread rain showers will take place during the morning, with more “off” than “on” during the afternoon and evening, but we still have to watch for a couple batches of showers until the front passes through, and that doesn’t likely happen until the evening hours. So that means we’re in the clear for Sunday, right? Not so fast. Yup, we’ll be behind the cold front, and Sunday will certainly be a cool day regionwide, but many would take that in trade-off for sunshine. However, upper level low pressure has to move across the area. And those contain plenty of cold air aloft. If you get any sun, you pop abundant diurnal clouds, in addition to any existing cloud cover with the upper low to begin with, so I’m looking for very limited sunshine on Sunday, and also cannot rule out a passing rain shower. At least the rainfall threat will be rather isolated, and any that do occur would be rather brief, in comparison to Saturday’s showers. So if you have to pick a day for the better of the 2 for outside activity, it’s Sunday, that is if you can handle the gusty breeze we’ll have, making the 50s feel more like 40s at times. Sorry! 😉 But hey guess what? High pressure builds in just as the weekend wraps up, and fair weather and a warming trend will be with us as many head back to work (and back to school after vacation). Yep. Timing is everything! 😉
