Showers possible at night & Sunday...

* NatCast | July 4th Guide | Current Temps and More: Weather Wall *

EXPRESS FORECAST

Today: Partly sunny. Mid-80s. | Tonight: Showers possible, mainly after 9 p.m. 60-66. | Tomorrow: Showers likely. 75-79. A Look Ahead

FORECAST IN DETAIL

For the bulk of Independence Day, we'll enjoy almost ideal weather. Temperatures will be warm but not hot, humidity will be held in check, and a pleasant breeze will blow. The fly in the ointment is an area of low pressure approaching from the west tonight that could produce showers in time for fireworks, but more likely should hold off until after midnight. Sunday's weather does not look terribly promising at the moment with clouds and showers a good bet.

Today (Saturday): Under partly sunny skies, temperatures will warm up nicely, probably into the mid-80s by mid-afternoon. Dew points will be near 60, so it shouldn't feel too humid. A light wind from the west will blow at 5-10 mph. The chance of any shower activity during the daylight hours is slim, and under 20%. Confidence: Medium-High


Radar: Latest regional radar loop shows movement of precipitation over past two hours. Powered by HAMweather. Refresh page to update. Click here or on image to enlarge. Or see radar bigger on our Weather Wall.

Tonight: Cloud cover will gradually increase throughout the evening. Low pressure moving in from the west will produce just a 25% chance of showers before midnight -- so most fireworks celebrations should not be threatened. After midnight, shower chances increase to about 50%. Lows will be in the low-to-mid 60s. Winds will be light. Confidence: Medium-High

Keep reading for the forecast for tomorrow and into early next week...

Tomorrow (Sunday): Low pressure likely (60% chance) produces occasional showers throughout Sunday. The track of the low isn't etched in stone and there's a chance most of the rainfall will fall just to our south. Regardless, there will be more clouds than not, with highs in the upper 70s. Confidence: Medium-High

Tomorrow Night: Showers should gradually clear the region followed by partly cloudy skies. Lows will again be in the low-to-mid 60s. Confidence: Medium-High

A LOOK AHEAD

Monday and Tuesday may both be very nice as weak high pressure builds over the area. Highs both days should be in the low-to-mid 80s with partly sunny skies and relatively low humidity. Overnight lows will be in the 60s. Confidence: Medium

We still had a shower early yesterday afternoon, but it is considerably drier than earlier this week.

Happy Fourth, CWG!

I think this is the very first Fourth of July on which I am not running my A/C. Crazy.

This is shaping up to be a fine 4th of July. A little while ago, a patriotic bear marched past the American flag in our backyard. If interested, image posted at:

High of 84° is the coolest July 4 without precipitation since 78° in 1996.
