As expected, yesterday was a bit warmer and bit mugger compared to our recent stretch of cool, comfy weather. While a few showers developed and moved through parts of western and northwestern Connecticut, many communities remained dry with a decent amount of sunshine.
A deep trough in the upper levels of the atmosphere is slowly lifting out of The Great Lakes region, around it pulses of energy combined with daytime heating are generating isolated showers and thunderstorms. Additionally, a southwesterly flow around the trough will continue to transport warmer/muggier air into the region, leading to further instability. Today, we anticipate a day very similar to yesterday, with the chance for unsettled weather during the afternoon and evening. Any storms that develop will be isolated to scattered in nature with heavy downpours being the primary threat with some gusty wind. Highs today will be in the lower to mid-80s and it will feel a bit more humid, but not oppressively so.
When it comes to the weekend, there is still some uncertainty to how unsettled our weather will be across Connecticut. A boundary currently positioned off the coast will drift back to the west, ending up in the vicinity of Southern New England. At the same time, waves of low pressure will ride up along the front, enhancing the potential for periods of steadier rain.
Tomorrow there will be a chance for isolated to scattered showers and storms with highs in the lower 80s. There are some indications that the soaking rain will arrive tomorrow morning and linger into the afternoon. Sunday is now looking like the better of the two weekend days with some partial sunshine, but don't rule out those scattered showers, maybe even some thunder. While the first weekend of August won't be a washout, there will likely be more clouds than sunshine with on-and-off chance for rain and even some embedded thunder.
Early next week, some showers or storms will be possible Monday. Then Tuesday, Wednesday and Thursday high pressure builds into the region – this means a period of dry weather with seasonably warm temperatures.
Make it a great weekend!
