DAYS 1-5 (JUNE 22-26)<\/p>\n\n\n\n
We’ve been fortunate with late spring weekend weather, with many nice weekend days and in a few cases entire weekends with no weather woes. This is our first weekend of astronomical summer, and might trigger a memory or two of how many of our summer weekends went in 2023. But this is merely coincidence and doesn’t actually predict anything about the weekends to come this summer. Beware – the mainstream media may try to convince you otherwise. Haha! Half-joking aside, our focus on this weekend’s weather highlights an unsettled pattern, but neither day a “wash-out”. The big ole ridge of high pressure that delivered a hot spell at mid week and started a retreat back to the west a little at the end of the week now sits in the Midwest, with our region on the edge of a quasi-ring-of-fire. The term “ring of fire” in association to weather refers to the edges of a high pressure ridge, particularly during the warm season, where disturbances and resultant showers and thunderstorms often track. We also had a back-door cold front move through the region yesterday, not only shutting down the heat at the surface, but also adding another ingredient into creating some showers and storms. We saw that yesterday as a pretty solid area of showers\/storms formed, then progressed slowly eastward, but weakened as it moved into the marine air over much of our forecast area. They didn’t dissipate quickly enough to avoid bringing rain to much of the region though, but they moved out late last night leaving us with a mainly cloudy, clammy atmosphere to start the weekend. So now what? Today, the frontal boundary that moved through yesterday will hang out to our southwest, and may help trigger a few additional showers and storms in the southwestern reaches of the WHW forecast area, while a disturbance riding the ridge moves across northern New England later today before exiting via the Gulf of Maine this evening. This disturbance can help set off a cluster or two of showers and possible thunderstorms that can traverse parts of the region this afternoon and early evening. There will be somewhat limited solar heating with the extensive cloud cover in place, so I don’t think any real organized severe storms will get going, but with the disturbance present, they should not be ignored either. I’d not cancel any outdoor plans today, but keep a close eye to the sky \/ radar and have a plan in place should you have to dodge something. The frontal boundary to the southwest will start to lift northeastward tonight and Sunday, and while we end up on the other side of it on Sunday, we won’t return to the high heat of midweek, but it will be noticeably much warmer and continued quite humid, with more sunshine than today will offer. A trough of low pressure will be moving eastward into this warm and humid air mass during the day, and with more solar heating to work with, a more organized cluster or line (or two) of showers and storms should form to our west and move into our region later in the day or early evening. I can’t rule out isolated showers and storms ahead of this, but I do think most of the daytime will be rain-free, just muggy and very warm, but with a somewhat helpful busy southwesterly wind at least moving the air about for ventilation. So keep a watch for the late-day storms, which can be strong to locally severe. There’s even some potential for rotating storms, especially if they are not part of an organized line, with more wind shear present in the atmosphere. In addition, the unstable atmosphere lingers into the nighttime, allowing for additional development of shower\/storms behind any main cluster(s) \/ line(s). In additional to severe weather potential (hail \/ strong wind) with some storms, areas that see some heavy rain training can be prone to flooding. Activity should settle down late at night \/ overnight \/ early Monday, but we still have a cold front to traverse the region during Monday, probably not passing through until sometime Monday evening. So we’ll see a renewed threat of showers and thunderstorms Monday – another unsettled day. Finally, a nice Canadian high pressure area will deliver fair weather with drier air for Tuesday, but the progressive nature of the pattern will allow that high to slide offshore, making Wednesday warmer and more humid, but with a continuation of fair weather. I hope you read all of that carefully. I might give you a pop quiz. \ud83d\ude09<\/p>\n\n\n\n
TODAY: Mostly cloudy. A possible shower and a slight chance of a thunderstorm at any time this afternoon and early evening. Highs 68-75, coolest coast. Dew point 60+. Wind E up to 10 MPH.<\/p>\n\n\n\n

Highs 75-82 South Coast, 82-89 elsewhere. DP rising to near 70. Wind S to SW 10-20 MPH, but can be variable, strong, and gusty near any storms.<\/p>\n\n\n\n
SUNDAY NIGHT: Mostly cloudy. Additional showers and thunderstorms possible. Areas of fog. Lows 65-72. DP 60s. Wind SW 5-15 MPH, diminishing, but can be briefly strong and gusty near any storms.<\/p>\n\n\n\n

DAYS 6-10 (JUNE 27 – JULY 1)<\/p>\n\n\n\n
A cold front passing through the region brings a shower and thunderstorm chance June 27, timing uncertain this far in advance. High pressure builds in with refreshing air June 28 then moves overhead then offshore during the final weekend of the month and to greet July, with a warm-up.<\/p>\n\n\n\n
DAYS 11-15 (JULY 2-6)<\/p>\n\n\n\n
Holiday time period forecast which will have much scrutiny and importance. Large scale pattern looks like a progressive west to northwest flow with an upper high pressure ridge back in the Midwest region. This keeps us out of persistent heat but also leaves the door open for a couple rounds of passing showers\/storms with disturbances moving through, so it’ll come down to timing regarding travel \/ summer holiday plans. And we have a long way to go before we can fine-tune those details, but there’s your early general idea. Actually looks like a pretty decent pattern overall.<\/p>\n","protected":false},"excerpt":{"rendered":"
