After some early morning showers/cloudiness, the rest of the day will feature sunshine and seasonable temperatures as they peak in the lower to mid-60s.
As we have been forecasting, it is going to get quite chilly tonight. In fact, a Frost Advisory has (so far) been issued for northern and northeast CT (Litchfield Co could get added at some point) as temperatures dip into the 30s inland by daybreak Friday. Since it has been a while since we’ve had an alert like this: they’re typical for this time of year, one is issued when frost could play a role in the growing season (which is still underway, since we’ve yet to have a widespread freeze). Tomorrow afternoon will again be fairly typical by mid-October standards with highs in the mid-60s.
For the weekend, Saturday still appears to be mostly cloudy with the chance for some isolated to scattered showers… but not a washout, by any means. Those participating in any of the Hartford Marathon Foundation races in the morning may encounter some light rain and should plan for temps in the lower 50s at the start then they'll warm into the mid to upper 60s by Noon. Sunday, there could be an isolated shower early… otherwise we should see sun and clouds with temps reaching into the 75 to 80 degree range that afternoon.

A disturbance that brought us some showers yesterday and overnight will move away to the east of New England today as high pressure builds southward across the region. That means weather conditions will improve. Morning clouds will give way to partly to perhaps mostly sunny skies during the afternoon. The air will be seasonably cool with afternoon highs in the 60s.
Tonight could get quite chilly, especially if the sky remains clear. As a matter of fact, the National Weather Service has issued a FROST ADVISORY for Hartford, Tolland and Windham counties, so you might want to bring in those plants. We're expecting overnight lows to drop between 35-45 degrees. Again, scattered frost is possible in the normally colder valleys by dawn tomorrow.
Friday is looking good with partly sunny skies and highs in the 60s. As high pressure moves away to the east of New England, an east or southeasterly breeze will develop. This ocean flow could spread low clouds into the state. However, timing the arrival and the extent of the cloud cover is difficult. For now, we’ll generalize and go with a partly sunny day.
A WEEKEND WARM-UP…
There has been a change to the weekend forecast. It now looks like showers are possible late tomorrow night and Saturday morning. Although there may be a hint of high pressure in Southern New England, a weather system known as an inverted trough could produce clouds and showers. We are hoping the showers will be light and not negatively impact the Hartford Marathon/Half Marathon. Some guidance models keep the threat of showers going into the afternoon, while others suggest the showers will end and the sky will just be mostly cloudy in the afternoon. It should be a fairly comfortable day with highs ranging from 70 to perhaps 75 degrees.
We still believe Sunday will be unseasonably warm. A strong southwesterly breeze will develop as a storm system races across the Great Lakes region and then into Eastern Canada. Temperatures will rise well into the 70s to near 80 degrees and the southwesterly breeze could gust to over 30 mph during the afternoon. Humidity levels will be on the rise as well. Dew point readings could top 60 degrees Sunday afternoon.
A cold front will move rapidly across Southern New England Sunday night with a band of showers and perhaps even a thunderstorm or two. The wet weather should be gone by dawn Monday as a northwesterly flow of drier air develops.
Monday should be partly sunny as a strong northwesterly breeze ushers in cooler air. Daytime highs will be limited to the 60s. Clear skies and diminishing winds Monday night could allow temperatures to dip into the 30s in many outlying areas.
Tuesday and Wednesday look great with high pressure in control. Both days should feature mostly sunny skies and seasonably cool temperatures. Nighttime lows will be in the 30s and 40s, and daytime highs will be in the 60s.
