Phoenix weather: Thunderstorm ThursdayPosted: Updated:
PHOENIX -- An upper-level low-pressure system making its way into Arizona from Southern California is the trigger for numerous showers and thunderstorms around the state, especially in western Arizona.
The potential for severe thunderstorms will be in the forecast tonight, with some of the storms exhibiting strong winds, heavy rain and perhaps hail. The storms will be moving fairly rapidly, so we do not anticipate the threat for widespread flash flooding is that high. However, locally, the storms will be able to produce a lot of rain in a short period of time.
As the upper-level low moves through, it will also drag in a bunch of much drier air. As a result, for Friday and the weekend, we’ll see a big dropoff in the number of thunderstorms statewide and we’ll start to warm up as well. Still, high temperatures will be in the range of 100-105 degrees for the weekend, about average for this time of year.
So far in monsoon 2014, Sky Harbor Airport has received a bit more than 1 inch of rain, well below average. But the forecasts for a late-breaking, strong monsoon seem to be coming to fruition, so it appears we’ll add to that monsoon total before the season ends on Sept. 30.
