Forecast – for Aug. 5, 2010

It has been a tough couple of months for the weather models during what is usually a fairly easy time of year to forecast. The main reason for this is because there has not been a single strong controlling weather system that has dominated our weather this summer. Instead, we have been experiencing weak systems that make it tough to figure out just how much sun, clouds, and rain we might see.

I know we’ve been talking for several weeks about a strong area of high pressure building in and bringing us an extended period of warm, dry weather, and each week that promised high seems to get pushed back. Well, it finally looks as though that high will build in, but it just might not last for that long.

The models are showing a strong area of high pressure building to our west, and we should start to see it move in on Wednesday. Initially we will be in a northerly flow on the east side of the high. This will cool temperatures down a little bit on Wednesday and Thursday. As the high moves over our region on Friday and Saturday, temperatures will warm up and we should see highs in the upper 20s to around 30.

Once the high pushes to our east we will once again move into a weak pattern with plenty of weak areas of low and high pressure affecting our region. This means a return to partly cloudy days, with slight chances of showers and thunderstorms on any given day. Temperatures look like they’ll remain warm, with highs continuing to be in the upper 20s to around the 30 C mark, which is right around the top end of the usual temperature range for this time of the year.

Usual temperature range for this period: Highs:21 to 30 CLows:8 to 16 C
