Pinpoint Weather: persistent pattern of coming storms

This evening looks muggy and balmy with a chance for some fog pockets and some mist and drizzle. As the short work week approaches, there will be a regular pattern of afternoon thunderstorms. The challenge is not whether the storms will occur, but where and how strong.

The Storm Prediction Center placed the region in the light and marginal risk categories for severe storms on Tuesday and Wednesday. The main threat should be gusty winds and hail nearly 1″ in diameter.

There is also a very low risk of a spin-up tornado developing in one of the problem clusters tomorrow, so we need to be aware of the weather. As mentioned, the odds are low, but still seem to be on the table with this type of stormy pattern. Futurecast isn’t impressed with Tuesday’s stormy potential, but this model updates every six hours, so we’ll keep an eye out. The threat of severe weather intensifies on Wednesday, so that day could be the more aggressive of the two this week.

The stormy pattern will continue through the weekend as summer heat and humidity will be present to stir up the atmosphere. A frontal boundary will also block us over the region on Thursday and Friday and this feature could help unleash storms on the Commonwealth.

Temperatures will be warm, hitting or approaching the low to mid-90s for most of the week, and with the humidity the region will also see the possibility of triple-digit heat index values.

Be careful,

As for the tropics, Bonnie has made it through Central America while maintaining her tropical characteristics as she grows in the Eastern Pacific. The name remains, unlike Agatha who crossed from the Pacific to the Gulf of Mexico. This cyclone lost its status over the mountains and became Alex a few days later. Now Bonnie continues west and gains power.

This year, in the books, the Eastern Pacific basin will have two cyclones whose names begin with the letter “B”, Bonnie and Blas.
