Summer in October
Posted by Pete Bouchard
If today's warm temperatures didn't get your attention, then maybe this summer-like Severe T-Storm Watch did:
A squall line - more typical of mid summer - is marching east tonight. Gusty winds and torrential downpours will hammer Greater Worcester from 7-8 and Greater Boston by 8-9pm. There may be some localized, brief flooding as the storms move through. Reason for the strong wind gusts? Thunderstorms are like playground slides. They can transport high level winds down to the ground (just like a kid on the slide).
When the wind is strong enough, we get microbursts like the image above shows. Conditions are favorable for these microbursts, but if they do occur, they should be very isolated.
Winds outside of the storms have created damage too. From Chelsea to Lowell tree branches and wires have been taken down by gusts of 40+ mph. Hold onto the steering wheel tonight!
What's remarkable is how these storms are monopolizing the wind. Once they pass - within 30-40 min. mind you - the wind almost shuts down completely. Expect that after 9-10 tonight (8-9 in Worcester). Rest of the night will see quieter weather with decreasing clouds.
By tomorrow, there will be no sign of wind, storms or clouds. Sun's back, the weather is mellow and the temperatures seasonable.
We'll have updates as necessary.
