TUCSON - Monsoon makes a weekend surge courtesy of the tropics.
Scattered storms return to southern Arizona this afternoon as moisture continues to increase, according to Meteorologist John Patrick. Much like Friday some storms will be capable of turning severe with strong winds, hail and heavy rain.
Decaying tropical system Lorena in the eastern Pacific will send a surge of moisture into the region through the start of the upcoming work week. The best chance for showers and storms will be Sunday through Tuesday with periods of heavy rain being the main concern.
The amount of cloud cover we see during this time period will have an effect our rain chances. The more sun we see the more widespread thunderstorms will be, however, with thick cloud cover limiting our instability showers will become more abundant.
Temperatures will stay near normal in the high 90s to start the weekend. As moisture and clouds increase Sunday-Tuesday daytime highs will drop into the upper 80s and low 90s.
