TECHNICAL DISCUSSION

A big warm-up for the last weekend of summer

ROCKY HILL, CT (WFSB) -

THE LAST WEEKEND OF SUMMER

 Have you noticed the humidity has already come up and, despite the clouds, the air was a lot warmer today (74 degrees instead of 64 degrees)?  Indeed, changes are on their way that will make the last day of summer feel like summer and then further changes are on their way that will make the first days of fall feel classically "fall-ish." 

 Overnight will feel like summer; you can leave the windows open and save the extra blankets.  Lows will be in the 50s and low-60s with the warmer areas being within the urban cores and along the Shoreline.  Clouds will thicken and, by morning, scattered light showers and drizzle will move into the state. 

A storm system will be gliding up the eastern seaboard tomorrow.  The bulk of its rain will move to our east, but not all of it.  New model trends have been suggesting a tendril of moisture will come into Connecticut and present the chance for a few showers at some point Sunday.  Most models are saying that morning and early afternoon will be our most vulnerable time with enough subsidence late-day to allow the showers to cease and a little sun to shine.  Should this scenario pan out, our forecast of 80 degrees will be right on the money.  If the showers linger into the later afternoon(one model suggests this later end to the rain), 70s will be the maximum. Rain totals will not be impressive, with some towns receiving 0.1"-0.3", but with many locations receiving less.

Any reduction of cloud cover late day will be reversed tomorrow night as a cold front approaches.  With cloudy skies and yet another chance for showers,especially after midnight, readings will again be in the "summer zone" with lows around 60 degrees.

 

 THEFIRST WEEK OF AUTUMN

As if turning a switch, the weather will turn cooler and drier on the first day of autumn.  A cold front will pass through the state very early in the morning, pushing out the clouds, showers and humidity.  An increasing breeze through the morning will bring drier air into New England from the west.  The sky will return to the clarity we enjoyed late last week and temperatures will be milder, with highs in the low-70s. 

From Wednesday through next weekend, we will be in a long period of sunny, dry and mild weather.  Highs will reach into the upper-60s and low-70s while  night-time lows will be the 30s and 40s.  Typical cold spots may have frost during at least a few of these mornings.  Through at least Sunday,there is no projection for rain – and we need some.

ADRY SEPTEMBER

 [FromBruce:

"Through the first 19 days of September, only 0.49" of rain has been measured at Bradley International Airport in Windsor Locks.  If September ended right now, it would be the 2nd driest on record!  September of 1914 was the driest on record with only 0.20" of rain.  3rd place goes to September of 1948 with only 0.63" of rain.  Of course, there are still 11 days to go before this month is over, but it looks like this dry pattern is going to remain with us for quite some time.  We'll have to see what happens toward the end of the month."
