7/10- Beautiful Today, Storms Return Tomorrow?

Good Monday all-

Today is probably either the best or second best day of the year so far, with highs likely to be in the low to mid 80s with bright sunshine and low humidity. Unfortunately, tomorrow looks like a much more problematic day, with widespread thunderstorms likely, especially in the afternoon. The SPC puts the severe risk at a rather mundane MARGINAL risk, but that does mean we have to watch out for some gusty winds & medium sized hail.  The rest of the week will feature a risk of thunderstorms literally each and every day, with the best chance coming Thursday night and Friday.

In the Atlantic- A complex forecast is developing with a new tropical wave off the African coast. The GFS develops a major hurricane in the Caribbean by the end of the week...whilst the Euro kills the system on Wednesday. That's about as divergent as they get...so we shall see which is right. It's much too early to determine where this will travel, but models have suggested this one could be a threat to the United States. Additionally, the remnants of Tropical Depression #4 are trying to redevelop east of Florida, but that seems somewhat unlikely at this time.

Pacific- Major Hurricane Eugene has weakened and will now die as it gets into the colder waters of the northern Pacific. It poses no threat to land except for rip currents on the Baja California peninsula.

Today in weather history- July 10, 1989- A massive F4 tornado strikes Hamden and New Haven CT, doing over $100 million (1989USD) in damage. This is, although unusual, not unprecedented for the state- it is one of only 3 F4 tornadoes in state history- the others were in Windsor Locks in October 1979, and in Wallingford in August 1878 (which remains the deadliest tornado in state history)
