Remember this post from Tuesday morning in regards to Wednesday’s back door cold front?
“The next front to pass through the region is missing quite a few ingredients in order to produce some showers. It is set to slip through the region tomorrow afternoon. First off, it has very little moisture to work with. Dew points are likely to sit in the 50s during this timeframe. The area of high pressure to the south of us will block the transport of moisture for quite awhile. Secondly, the parent low of this cool front is well up into Canada so there is very little forcing or upward movement to kick up some wet weather. ExacTrack is trying to produce some isolated showers but with the rain chances so low, I’m keeping the forecast dry. However, I will call for some fairweather clouds to develop Wednesday afternoon.”
Well, there is another back door cold front set to swing across the region Saturday afternoon. This ExacTrack picture is outputting the same scenario, by trying to produce some popcorn showers late in the day on Saturday. Even if there is somehow enough instability in the atmosphere, the activity is going to be quite sparse. I would say our rain chances during this time period are roughly 10%. I took the liberty to issue a “BBQ Alert” this morning for the next three days. So fire up the grill and throw on some burgers and brats, or if you prefer: steaks and chops! -ADAM
