The rest of today will feature a mix of sun and clouds, also a slight chance for an isolated shower with the daytime heating as there is some lingering instability in the wake of yesterday's storm system. Temps reach the upper 60s and 70s for highs.
Tomorrow, there will be another chance for some showers during the afternoon… it will also be a bit cooler than today by a few degrees.
Forecast for the weekend is on track – sunny/dry both days, but cool for early September: morning lows in the 40s... highs in the 60s Saturday, 70s Sunday.
With regard to Irma, the Turks and Caicos are in the path of the storm later today; then it will head into the Bahamas, with the eye paralleling and passing just north of Cuba. A Hurricane Watch has been posted for southern Florida as Irma will approach the Sunshine State this weekend. The latest model data and official forecast track from the National Hurricane Center bring the core of the storm up Florida's east coast and then toward the Georgia/South Carolina border early next week.

MUCH BETTER WEATHER TODAY…
All of the rain associated with the system that plagued us yesterday is now gone, and we'll see clearing skies as the result of a dry northwesterly flow. That will allow for the mercury to rise into the middle and upper 70s this afternoon while dew points drop into the upper 40s, so it will feel quite pleasant outside. However, there will be some instability around thanks to an upper-level low in the area, so there may be a shower or two this afternoon, but most of us should remain completely dry.
Any leftover showers should come to an end after sunset, which is 7:14 this evening, setting us up for a mainly clear night tonight. Lows will be in the upper 40s and lower 50s.
SHOWERS POSSIBLE FRIDAY AFTERNOON
The upper-level low will move closer to us Friday, thus there will be some more instability in the atmosphere. That will bring the chance for a few more showers tomorrow afternoon, a few more showers than we're expecting today. With that said, most of Connecticut should remain dry. Temperatures will be on the cool side tomorrow afternoon, 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 tomorrow 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 for Saturday. 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 over inland Connecticut will likely not rise out of the 60s Saturday afternoon, so it will be a good taste of autumn! High temperatures along the Interstate 95 corridor will be slightly warmer Saturday, with readings near 70 degrees expected.
Skies will be mainly clear Saturday night and winds will be light. That will make for a chilly night Saturday night, with lows bottoming out in the 40s in most places with some of the normally colder towns dipping into the 30s. 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 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…
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. If this scenario unfolds, that will mean potentially heavy rain for us Wednesday, though fortunately nothing like those directly impacted by Irma will get! We are currently forecasting highs in the 70s for Wednesday, but that is subject to change depending on exactly what happens with Irma and the Canadian system.
Hurricane Irma is moving just to north of Hispaniola this morning as a dangerously strong Category 5 hurricane with maximum sustained winds of 180 mph. It is one of the strongest hurricanes on record in the Atlantic Basin and the strongest hurricane outside of the Gulf of Mexico and Caribbean Sea. When it comes to wind, Hurricane Allen (1980) was the strongest with maximum sustained winds of 190 mph.
There are devastating reports coming out of places such as Barbuda and St. Martin. Irma will move toward the west-northwest over the coming days, impacting the Dominican Republic, Haiti, Cuba, the Turks and Caicos, the Bahamas and eventually Florida over the weekend. Irma is expected to remain a major hurricane throughout this period.
The impact Irma will have on Florida and the rest of the southeastern United States will greatly depend on the exact track, which remains uncertain. Most of our computer models take it very close to Miami by the time we get to Monday. 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 middle of next week.
