A cold front is slowly moving east this evening at the same time warm and humid air has moved into much of southern and central New England. Over the next several hours we will be watching a line of storms that moved out of New York and Pennsylvania earlier today cross eastern Massachusetts and the rest of New England. As the storms move east they are weakening and will produce some heavy rain and thunder. I don’t expect any severe weather around Boston.
A tornado watch is up for Berkshire county and is in effect until 9pm. A tornado watch is also up for parts of Vermont. This means conditions exist that are typical for tornadoes to form. If a thunderstorm forms, that meteorologists at the National Weather Service think will produce a tornado, they will issue a tornado warning. A watch, while significant, is not as severe as a warning. With a watch, you should just listen to the radio, watch TV or use the internet to monitor the latest advisories. A severe thunderstorm watch is up for New Hampshire and central Massachusetts until 10pm. This means severe thunderstorms are possible.
The map below shows, in yellow, where a tornado watch is up across the eastern part of the country. The orange boxes are severe thunderstorm warnings. These will expire as the storms move east and new warnings will pop up. The pink/red area is the area that severe thunderstorm watches are now in place. These watches mean that conditions favor severe weather. When a severe thunderstorm does show up on radar, a warning is issued. I expect a new severe thunderstorm watch to be issued further east over the next few hours. Stay tuned for that. What is happening behind the scenes right now is that the folks at the Severe Storms Center in Norman, OK are monitoring the atmosphere at all levels and deciding when and if to issues these watches. The watches are issued by that office. The actual warnings are issued by the local National Weather Service offices. Our closest one is in Taunton. Others, like in Albany, Portland and Burlington, VT will be issuing warnings if they are needed.
The latest radar shows the strong line of storms. This line is moving east and will be pushing across New England during the first part of the night. You can click here to see a live radar.
The front we have been talking about all week has now moved north of the Mass Pike. To the south, temperatures are reaching the middle and upper 80s with humidity. It will remain cooler along the coast especially north of Boston into New Hampshire and Maine. As I am writing this, it’s well over 80F in parts of metrowest and only in the 60s in Boston. The thunderstorms to our west will be moving through into this cooler air they will fall apart. Thunderstorms do not like cool ocean air. Boston should remain on the cool side for the evening so they will not see any severe storms. I expect this to be the case. It’s nearly impossible to get severe weather in cool ocean air. However, back to the west of route 495, the air is much more humid and there could be severe weather in that area.Follow me on Twitter for the latest updates at @growingwisdom
Wednesday, we watch the cold front moving in from the west, as this front moves through, more showers and thunderstorms will pop up. The day will be humid, especially though sunset. After dark, drier air will start to move into the region and our air will become more comfortable. This will translate into a great day Thursday, my pick of the next several days.
Gardening this week.
Tomatoes are the most popular vegetable to grow for many of you and there are so many varieties that are out there. Check out this video on a few of my favorites. Maybe you have a container or one last spot in the garden to try one.
