The heat continues to build Saturday, with the possibility of an isolated shower or storm.
A cold front moves closer, but it will also be in the process of washing out as high pressure takes command. Thus, an isolated storm is possible, particularly in the north and west, but many stay dry.
Temperatures will peak in the upper-80s inland and middle-80s on the shoreline. Humidity levels will be moderate.
Tonight will be mostly clear and slightly more humid, with patchy fog heading into the morning. Lows will be in the 60s.
Sunday is hot and dry with abundant sunshine, moderate levels of humidity and temperatures in the lower-90s. It will likely be the start of a heat wave!
Highs in the middle-90s are expected on Monday with mostly sunny skies. A Bermuda high-pressure system results in a southwesterly flow in Connecticut and that pumps in the heat and humidity.
Unlike many heat waves, the air will still have a dry feel to it on Sunday and Monday. It’s not until Tuesday that it becomes very humid and that humidity sticks around though the middle part of next week. There will be a mix of sun and clouds on Tuesday, with the chance of an isolated shower or storm. Temperatures will be in the lower-90s Tuesday, before falling back into the 80s on Wednesday.
Another cold front approaches late Tuesday, but it doesn’t come close enough to Connecticut to cause widespread storms.
Any shower and thunderstorm activity on Tuesday and Wednesday looks to be isolated, occurring especially in the higher terrain where the lift will be enhanced.
Three or more consecutive days of 90 degree weather makes a heat wave. So far this year, only one has occurred and that was in July. Keep in mind, the average high temperature is only in the lower-80s this time of year!
A low-pressure system rides along the cold front near the Great Lakes and lifts the front north as a warm front by the middle part of next week.
Thursday should turn out dry during the day before the possibility of numerous showers and thunderstorms arrives on Friday.
