Heat Wave Possible Early Next Week

Sunny skies dominate for the rest of this Friday with temperatures in the middle-80s.

Storms in New York State might approach the northwest corner late, but that would be the exception and not the rule.

Tomorrow the heat continues to build. 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, but many stay dry.

Temperatures will peak in the upper-80s inland and middle-80s on the shoreline. Humidity levels will be moderate.

Sunday is dry with abundant sunshine, moderate levels of humidity and temperatures in the lower-90s. It will likely be the start of a heat wave!

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.

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. Temperatures will be in the lower-90s Tuesday, before falling back into the 80s on Wednesday.

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.
