Rain chances remain high
(WALA) - Rain chances remain unusually high for the next several days with a moist airmass in place.
We continue to be in a weakness in the upper atmosphere between two ridges – one over the desert southwest and the other centered over the Atlantic Ocean. We are also seeing a continual light and effective southerly flow at the surface.
The result is above average rain chances all week with locally heavy downpours possible. A surface front will edge closer to the area Friday. Most places have a 70-80 percent chance of showers and thunderstorms each day.
Our rain chances lower a little through the weekend. We are tracking an active tropical wave in the Atlantic several hundred miles southwest of the Cabo Verde Islands. This wave has a very low chance of development as it heads generally westward.
Long range models show a more hostile environment by the end of the week, and it is not expected to impact the US. We are expecting an uptick in tropical activity as we head towards the middle of the month.
