Technical discussion: A great first weekend in October! Unstable weather at the start of the week … | Technical discussion


We’re starting with freezing cold this Saturday morning! Temperatures across our state range from the mid 1940s in the NW and NE corners to low 50s along the SW shore. Our normal low temperature for October 2 is 47 degrees and the coldest nighttime temperature on record was reported at Litchfield High School only at 38 degrees.

Today will be globally spectacular! The skies will be mostly sunny and the highs will be in the lower-mid-1970s with a light southwest breeze, well above our normal maximum for the Greater Hartford area of ​​69 degrees. It’s the last weekend of the big e and there are many fairs taking place in our state – it’s the perfect day to enjoy it.

Hurricane Sam will pass at sea well east of New England this weekend. A tropical storm warning is in effect for Bermuda, but for us the only effect we’ll see will be dangerous backwash and return currents along the ocean facing southern New England beaches due to these swells.

Tonight the weather will be generally clear and milder with lows ranging from 50 to 59 degrees. We might see some uneven fog early tomorrow morning.

We remain generally sunny for tomorrow morning, but clouds will form by the afternoon as a cold front plunges over northeastern Massachusetts gradually dipping south. Temperatures will again be above average in the 1970s! However, we can expect the onset of unstable weather late Sunday evening, well before a slow cold front that will bring us rain early in the week.


The cold front will land south of Long Island on Monday and Tuesday. During this time, the high pressure will develop towards southern Canada to northern New England. The humid northeast flow between these 2 systems will result in a period of cloudy and humid weather for Connecticut. Periods of rain and drizzle can be expected on Monday, and peaks in the 1960s. Tuesday may not be so humid, but there will still be rain and drizzle at times. The highs will again be in the 60s. Between Monday and Tuesday, Connecticut could receive 0.5 “to 1.5” of rain.

We should see some improvement on Wednesday and Thursday with high pressures centered on New England. However, this may not be enough to completely remove the moisture. There may be persistent rain Wednesday morning, then partial clearing is possible later in the day. The peaks should be in the upper 60s. Thursday should be partly to mostly cloudy with a few isolated showers possible in the afternoon. Temperatures could reach the lower 70s. Friday can be the nicest day of the week with partly sunny skies and highs of 65-70.


September entered the record books as a humid and mild month. Precipitation for the Greater Hartford area was 6.81 “, or 2.42” above normal. It was the wettest September 17th on record. The wettest September on record was in 1938 when precipitation totaled 14.59 “. For Bridgeport, it was the 2nd wettest September on record with 8.38 inches of rain! The wettest September on record dates back to just 3 years ago, in 2018, when rainfall was 8.59 “.

The average September temperature for the Greater Hartford area was 66.1 degrees, 1.3 degrees above normal. The average temperature at Bridgeport was 69.8 degrees, or 2.2 degrees above normal.
