Today: Showers likely, mainly in the morning. 75-79 | Tonight: Clearing, cool. 57-63. | Tomorrow: Warm and dry, 83-86. | A Look Ahead


A cold front that approached last night becomes stalled overhead keeping us gray and cool for a large part of today. We're likely to get a good dose of rain this morning before slowly drying out later on. Behind the front lies a dry and beautiful end to the week before sticky August weather returns this weekend. Sunday into early next week could see several days competing for the hottest day of the year so far.

Today (Thursday): We'll be "riding the wave" today as a wave of low pressure develops along a stalled cold front that brings along with it a 60% chance of light-to-moderate rain showers mainly this morning, although an isolated shower or t'storm could pop up (20% chance) later in the afternoon. I don't foresee any widespread severe weather or flash flooding problems.

With lots of clouds and the likelihood of rain, temperatures will struggle and we'll spend the majority of the day in the mid-to-upper 70s. If our wave gets some giddy-up and moves out sooner than expected, some afternoon and evening sun may be able to push the mercury above 80. Expect a wind from the north/northeast at less than 10 mph. Confidence: Medium-High

Probability: <20%
Coverage: Isolated

Tonight: Skies should begin to clear out by, or shortly after, sundown, paving the way for a very nice night. Behind the cold front, the dew point (moisture in the air) drops as well as the temperature. Overnight lows will likely spur some to open those windows, bottoming out in the upper 50s to lower 60s (downtown). Light northerly winds will become calm overnight.
Confidence: High

Keep reading for the forecast through the weekend...

Tomorrow (Friday): Transient high pressure takes hold tomorrow spelling a gorgeous day, especially for August. After some patchy morning fog mixes out, expect boatloads of sunshine with a few puffy afternoon clouds overhead. With dew points in the 50s, it will feel more like May as we warm up to our afternoon high in the mid-80s. Winds from the north will continue to blow at less than 10 mph. Confidence: Medium-High

Tomorrow Night: It will remain partly cloudy for the most part, though some clouds will increase towards morning, along with an isolated shower or thunderstorm (<20%). Light winds will turn southerly and begin to bring our humidity levels back up. Confidence: Medium-High


Saturday we'll return to normal around here. Typical heat and humidity come back to the region and a weak disturbance may bring a cluster of thunderstorms through by evening (30%). Expect a mix of sun and clouds and an afternoon high in the mid-to-upper 80s. Overnight, showers will wind down and we'll have humid conditions with an overnight low in the lower 70s. Confidence: Medium

Beginning Sunday and into next week lies our best chance for an official heat wave so far this summer. A Bermuda High will expand to the southwest and pump in warm and humid air. After lingering clouds move out during the morning expect temperatures to climb quickly into the low-to-mid 90s. Confidence: Medium

"I don't foresee any widespread severe weather or flash flooding problems but be a rumble of thunder and some locally gusty winds can't be ruled out."



What kind of sentence is that?

"...but be a rumble of thunder..."
Especially that part.

Actually, I kind of like the way that sounds...

But the sentence is still screwy!

There was a typo which we've fixed. The word "be" shouldn't have been in that sentence...

Better . . . but really it should read "I can't rule out a rumble of thunder . . . " in order to maintain parallel structure.

Anyway, it looks like the rain (what little there was) had pretty much moved off).

The rain has been very light and more like a fall rain than a summer storm. Sterling has virtually removed thunder from the rest of the day for today.

The Atlantic tropics remain quiet. There is a weak low on the ITCZ west of Cape Verde, which might bear watching, but could get washed out by any significant El Nino wind shear. East Pacific Hurricane Felicia is near or just past peak strength @ 140 mph; remnants could still pose a threat to Hawaii, but biggest effect could be what Hawaiians generally don't mind--time to wax the boards; surf's up in favored areas.

I really dislike these sort of days in the summer. It's cool out, but still humid enough that just walking outside for any length of time still breaks a sweat and everything just feels damp. Luckily there's some dry air on the way, just over the mts.
