As expected, today 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. Any lingering shower activity will diminish with the setting of the sun making for a very nice evening! Some patchy fog could develop by daybreak Friday with temperatures dropping into the upper 50s and lower 60s.
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. Tomorrow, we anticipate a day very similar to today 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 for Friday 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.
Saturday 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 later Saturday and linger into part of Sunday. With more clouds than sun it will be a bit cooler Sunday, with temperatures peaking in the upper 70s. The first weekend of August will not be a washout, however there it will likely more clouds than sunshine with on-and-off chances or rain with 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 night!
