For tonight, clouds increase, especially along the south coast. This could create a wider than normal temperature range, as northern areas radiate, while southern areas really don't. Expecting low temperatures from the mid teens to the mid 20s.
A storm system will approach later tonight into tomorrow morning. A six hour or so period of light snow is possible in the southern half of the state tomorrow morning, especially right along the south coast. However, even this is not certain, and could be just flurries or even virga (which is precipitation that does not reach the ground). Therefore, the best way to play it is to just call for a chance of a snow shower. Obviously, other than a very light dusting on colder surfaces, widespread accumulations are not anticipated. Temperatures tomorrow will be fairly uniform across the state, due to the fact that northern areas may see some dim sun and southern areas may see some snow showers. High temperatures tomorrow should generally be in the upper 30s throughout the state.
For tomorrow night and Saturday, we'll be in between weak storm systems. With clear skies tomorrow night, most areas should fall to the low to mid 20s. On Saturday, once again, clouds will increase along the south coast, as a clipper passes to the south. Further north, sun will dominate the weather. Therefore, once again, temperatures should be fairly uniform, with highs around 40 throughout the state.
A clipper system will pass to the south of the area Saturday night. Once again, most of the precipitation will remain to the south. However, the south coast may be close enough to get clipped by some light snow. Since this system is further out and its ultimate result will not be determined until tomorrow afternoon, it's not out of the question for an inch or two of snow to fall along the south coast, once again in a quick period.
Longer Term: The longer term picture will be dominated by a gradually warming pattern. As skies clear out on Sunday, but the south coast takes longer to clear out, high temperatures should be close to 40 statewide. On Monday, with lots of sun, highs should get to the mid 50s. On Tuesday and Wednesday, high should get to the upper 50s. Our next chance of some rain will be on Thursday most likely, as a back door cold front approaches from the Northeast. It will also be a bit cooler on Thursday, with highs around 50. For Friday, skies clear out with temperatures in the 50-55 degree range.
The long range looks like a fairly typical springtime pattern, with temperatures at or above normal and a cold frontal passage every couple days. Of course, coastal locations will have to watch for cooling sea breezes, as Long Island Sound waters are still very cool.
Here are a few maps, graphically describing the upcoming weather pattern. First, let's take a look at the coastal low that is largely going to miss the state to the south.
That's all for tonight!
