While we’ll have to wait a little longer for perfect bluebird skies to return, today’s weather will be a marked improvement over the clouds and showers we saw yesterday. Yesterday’s cold front is fizzling out to our east, and clear skies have returned to all but eastern parts of the area as of this morning. Breaks of sunshine should become more frequent later in the morning especially along and west of the Turnpike.
This sunshine combined with some leftover moisture and cooler air aloft will set the stage for some instability this afternoon.
This map from the HRRR model shows about 100-250 J/kg of CAPE (a measure of thunderstorm fuel) which is right at the lower end of what’s needed to produce a few showers. With a secondary cold front swinging in from Quebec, I think we could manage to see a few showers over the mountains this afternoon (note the blue dots indicating such precipitation in the forecast map above). There is certainly not enough instability to support any type of severe weather so impacts from showers this afternoon will be minimal.
For those of us outside the mountains, we’ll see enough instability for a field of cumulus clouds that will periodically dim the sunshine but that’s about it.
High temps today will range from around 70 in the north to around 85 in southern NH. Along the coast, winds will turn onshore later this morning and will keep temps comfortably in the 70s.
