Hot & Humid Weather Expected For The End Of This Week; Strong To Severe Thunderstorms Possible Sat

For This Afternoon: A sunny to partly sunny afternoon is expected across the region with temperatures between 80 and 85 Degrees. Winds this afternoon will be southwest at 5 mph. Tonight: A weak frontal boundary is expected to cross the region tonight. It appears that a few showers and perhaps an isolated thunderstorm or two will affect the entire area mainly during this evening. Low temperatures tonight will be near 60 Degrees. Winds tonight will be southwest at 5 to 10 mph. Thursday: An area of high pressure will build into the area during the day on Thursday bringing with it lots of sunshine throughout the day. High temperatures Thursday will be near 85 Degrees. Winds on Thursday will be northwest at 5 to 10 mph. Friday: A hot and humid day is expected on Friday as that high pressure system continues to control the weather. High temperatures Friday will be near 90 Degrees with uncomfortable humidity levels. Winds on Friday will be southwest at 10 to 20 mph Saturday: Tough forecast for Saturday as the weather and the severity of thunderstorms is going to hinge on when exactly a cold front will push through the region. Some of the weather guidance points to a frontal passage that occurs during the late morning and early afternoon hours, which would limit the severity of the thunderstorm activity. Other weather guidance points to a frontal passage that waits until late afternoon or during the evening hours of Saturday. Should this occur, then there would be plentiful amounts of unstable air to trigger strong to severe thunderstorm activity throughout the afternoon into the evening hours of Saturday. My Thinking Is That Saturday will feature very humid conditions under a mixture of sunshine and clouds during the morning. Showers and thunderstorms are expected during the afternoon with a decent possibility for strong to severe thunderstorms peaking around mid-afternoon. The main threats from any strong to severe thunderstorms look to be strong wind gusts, torrential downpours with street and urban flooding and frequent lightning. We are going to have to keep an eye on how the really unstable air lines up with some low-level wind shear. If these two atmospheric components line up, we may have to really keep an eye on possible isolated tornadoes. Sunday & The Fourth Of July: Sunday’s weather forecast will hinge on how quickly the frontal boundary pushes offshore. A slower progression of the front would lead to a showery day, especially south of the Mass Pike. On the other hand, should that front push rapidly offshore, it would lead to a fairly nice day on Sunday. For now, I’m thinking that Sunday will feature partly sunny skies near and north of the Mass Pike and generally cloudy skies south of the Mass Pike, along with some isolated showers. High temperatures Sunday will be near 85 Degrees. The Fourth of July looks partly sunny with high temperatures near 85 Degrees.
