TUCSON - Scattered thunderstorms are in the forecast to finish up the weekend.

Another chance to see thunderstorms develop in Southern Arizona exists this afternoon, according to Meteorologist John Patrick. High pressure centered to our east is continuing to draw up moisture from Mexico with the best chance to see storms initiate along the International Border once again today. As storms develop this afternoon in the higher elevations of Santa Cruz and Cochise Counties there could be enough moisture and instability to push them into the valleys including Tucson. A similar situation is setting up for the start of the work week with another chance to get scattered storms firing up on Monday.

Accompanied by the increase in moisture over the next couple of days will be slightly cooler daytime highs in the low triple digits. Drier air moves into the region, however, by the middle of the work week decreasing our storm chances and increasing the heat. By Wednesday temperatures soar well above average and near the 110 mark once again.
