TUCSON - Isolated thunderstorm chances start off your weekend.
High pressure centered east of the four corners regions is working to pull moisture into Southern Arizona, according to Meteorologist John Patrick. This will contribute to our chance to see some isolated thunderstorm activity across the region today including the Tucson metro area. We'll continue to see the dew points rise as we go into Sunday and Monday giving us our best chance to see thunderstorms make their way into the Old Pueblo. Our Monsoon Prediction Index will jump up to a 6 for these days giving us a moderate risk to see some storms turn severe. Enough moisture remains in Southern Arizona to keep isolated storms in the forecast for Tuesday.
As the humidity increases the temperatures start to drop back in to the low triple digits from Sunday through Tuesday. By midweek a drier air mass settles in and temperatures start to rise back up near the 105 mark.
