The jetstream continues to steer small weather disturbances our way. As of late, if it’s not zonal, we are stuck within a toughy pattern. This is why you will view a slim chance of an afternoon storm nearly everyday on the Accuweather 7-day forecast.
Today, the clouds and fog will be gradually clearing. Sunshine makes its gradual appearance by late morning. Then, a mixture of sun and clouds will give way to about a 20% chance of a stray storm between 2pm-8pm. There is basically no cap today along with CAPE values between 1500-200J/kg and LI values ~-2 to -4. So, if a storm does develop, it may become strong. High temperatures will be flirting with the daily convective temperatures. Consequently, we will have a chance of ‘busting’ the negligent cap. Highs will be 85-90F inland. A weak seabreeze will keep the coast closer to 80-85F.
A weak cold front that fails to completely move through the region will introduce a chance of afternoon and evening storms on Friday. The instability values will be a spitting image of Thursday’s values. So, there will be a few scattered showers and storms around as the cold front sags to the south. Highs will climb even higher into the lower 90s.
This weekend is setting to be hot and humid. Highs will be near 90F on Saturday with cooler temps at the coast. Sunday will continue to be hot as high temps near 90F. Saturday will be partly cloudy with a slim chance of an isolated afternoon storm while Sunday will have a better chance of late-afternoon storms for the suburbs west of Boston. These storms will slowly move east Sunday night along with an approaching cold front.
Scattered showers and storms can bex expected on Monday with a cold front making a clean sweep by the evening hours. The high temps will be in the middle 80s.
Both the GFSx and EURO show a sunnier and less humid day on Tuesday. Discrepancies are showing up the middle part of next week though. The EURO shows a deeper trough with New England under the gun due to PVA and the stalled front along the eastern periphery of this trough. The GFSx shows a drier solution and a less pronounced trough on Wednesday.
T.D. Five is heading towards the Lesser and Greater Antilles. Currently, the track takes it nearly due west as it heads just south of Jamaica and possibly towards the Yucatan Peninsula. If it becomes a Tropical Storm, it’ll be named ‘Ernesto’.
