Gorgeous Days Ahead! Plus Tracking Hurricane Irma

Posted: Updated:
HARTFORD, CT (WFSB) -

AFTERNOON UPDATE...

As a trough of low pressure moves through the region this afternoon with colder air aloft and the daytime heating, there will be a chance for a few showers and perhaps an isolated thunderstorm.  Temperatures will peak in the upper 60s and lower 70s.

The weekend forecast remains on track:  dry both days with a good amount of sunshine; mornings will be chilly with lows in the 45-50 degree range... Saturday, highs will be near 70; then Sunday, it will be a few degrees milder.

Hurricane Irma is currently moving through the Bahamas, away from the Turks and Caicos... the eye will likely stay north of, but parallel the coast of Cuba.  The storm is forecast to make landfall in southern Florida Saturday night, prior to dawn Sunday as a category 4 hurricane.

DRY & COOL THIS MORNING

Good morning everyone! The skies are clear and the temps are cool, lower than what we have seen the past few mornings.  Most of the state has bottomed out in the lower to middle 50s, but the normally colder towns did dip into the upper 40s.  

SHOWERS POSSIBLE THIS AFTERNOON…

An upper-level low will move closer to us today, thus there will be some more instability in the atmosphere over Connecticut.  That will bring the chance for showers this afternoon across the state.  We cannot rule out a rumble or two of thunder either.  That said, most of Connecticut should remain dry this afternoon.  Temperatures today will be on the cool side, as the Connecticut River Valley and the shoreline will only hit the lower 70s, while the higher elevations will fail to get out of the 60s.

Once again, any leftover showers will dissipate this evening once the sun goes down.  Skies will clear out and temperatures will drop into the 40s in most of the state – lower 50s along the shoreline – so it will feel very much like fall!

DRY & COOL WEEKEND…

A large area of Canadian high pressure will move towards us tomorrow.  That will allow our skies to be mostly sunny and our humidity to drop even further – dew points in the 30s and 40s.  Despite the sunshine, the air mass over Connecticut will be quite cool.  High temperatures in the Greater Hartford Area will struggle to reach 70 degrees while most of inland Connecticut will remain in the 60s, so it will be a good taste of autumn!  High temperatures along the Interstate 95 corridor will be slightly warmer Saturday, with readings in the lower 70s expected.

Skies will be mainly clear Saturday night and there will be light northerly winds.  That will make for a chilly Saturday night, with lows bottoming out in the 40s in most places.  If you are planning on going to the fairs in Bethlehem, Hebron, or North Haven Saturday night, you will want to bring extra warm clothing and perhaps drink a warm beverage!

Sunday will once again be mainly sunny, but it will be somewhat warmer as the air mass over Connecticut begins to moderate.  It will still be cooler than average, though, as highs will generally be in the lower 70s – with upper 60s in the Litchfield Hills.  The normal high at Bradley Airport for September 10th is 77 degrees.

The area of high pressure will be nearly overhead Sunday night, which will bring another chilly night.  Temperatures will bottom out well down into the 40s in much of the state Sunday night, while the normally colder towns see 30s for lows.

WARMING TREND EARLY NEXT WEEK…

The high will remain firmly in control of our weather Monday and Tuesday, keeping our skies mostly sunny.  The air mass will warm up, too, which means the mercury will climb into the upper 70s Monday after a chilly start away from Long Island Sound, and some lower 80s will even be possible Tuesday!  Near the coast, a sea breeze will develop since steering winds will be light.  That means highs only in the middle 70s there.  Monday night will still be on the cool side, though, with clear skies and lows in the 40s and lower 50s.  Tuesday night will be milder – middle to upper 50s – as there will be some more clouds present by then.

WATCHING REMNANTS OF IRMA FOR WEDNESDAY & THURSDAY…

By Wednesday an area of low pressure will track across southern Canada and drag a cold front across the northeastern United States.  The system will have the potential to pick up what will become the remnants of Hurricane Irma, which most of our computer models place over the Ohio River Valley by the middle of next week.  Exactly what happens over Connecticut Wednesday and Thursday will depend on exactly what Irma does after making landfall, so changes to the forecast are still very possible!

Right now, we are forecasting the Canadian system to begin to absorb moisture from Irma on Wednesday.  Thus, Wednesday will feature mostly cloudy skies with rain developing by the afternoon.  The air over Connecticut will still be pretty warm, so we will see highs well into the 70s despite the clouds and rain.

The system will get closer to us Wednesday night and Thursday, which will mean numerous showers and thunderstorms, some of which could produce some very heavy rainfall.  Depending on exactly how this pans out, we could get quite a soaking next week!  As for temperatures, Wednesday night will be mild with lows in the 60s, while highs on Thursday will be in the 70s.

Be sure to stay tuned to Channel 3 Eyewitness News as we continue to fine tune this part of the forecast!

HURRICANE IRMA…

After devastating parts of the Virgin Islands and leaving over one million people without power in Puerto Rico, Hurricane Irma is moving between the Turks and Caicos Islands and Cuba this morning as a dangerously strong Category 4 hurricane with maximum sustained winds of 155 mph.  Irma is also still having an impact on the Dominican Republic and Haiti, where very heavy rains and very strong winds continue this morning.  Irma will batter the Bahamas and the north coast of Cuba today as the storm continues to move to the west-northwest at 16 miles per hour.

From there, Irma will approach the coast of Florida.  The exact impact Irma will have on Florida and the rest of the southeastern United States will greatly depend on the precise track, which still remains a bit uncertain.  Most of our computer models take it very close to Miami by the time we get to Sunday.  From there, the models take the storm northward either over eastern Florida or just offshore.  If the system remains offshore, a landfall will then be possible in Georgia or the Carolinas!  We will keep you updated over the coming days since Connecticut has many interests in the Islands and Florida!   However, we can say Irma will not have a direct impact on our weather, maybe just some rain from the remnants towards the second half of next week.
