Summer Sizzle About to Fizzle

It’s going to be hot. It’s going to be muggy. But it’s going away soon.

Wednesday should be the hottest day of the week, according to NBCSanDiego weather forecaster Whitney Southwick.

“We're starting off with some clouds and fog hitting the coast but it won't last and, with the exception of off and on high clouds at times, we should have mostly sunshine to go along with the heat this afternoon,” Southwick said.

At the beaches it’s forecasted to be mid to upper 70s or even low 80s. Things get hotter inland.

“At the low end we'll hit the mid and upper 90s. In the warmest valleys we're looking for highs between 100 and 105 degrees, this in places like El Cajon, Escondido, the San Pasqual Valley or the Ramona Airport,” Southwick said.

There is a chance of showers or isolated thunderstorms in our mountains and deserts. Some of that sub-tropical, monsoonal moisture will hit the County, so it will feel muggy.

By the weekend, it’s a much different story. A low-pressure system is expected to bring weather similar to what we saw in July. It’s forecasted to be cloudy at the coast with highs in the 60s. In the valleys temperatures will fall back down to 80 below.
