TUCSON - The first big break of Monsoon 2011 is about 48 hours away.

According to News 4 Meteorologist Jeff Beamish, enough moisture remains in place for isolated valley/scattered mountain thunderstorms Monday. A few storms will be capable of locally heavy rainfall.

Storms Tuesday will be east of a Casa Grande-Sells line, with the best chance in Cochise, Graham and Greenlee Counties.

By mid-week, a Pacific trough will scour out Monsoon moisture. A southwesterly flow aloft will push thunderstorm chances into New Mexico starting Wednesday. Daytime highs in Tucson for the middle to latter portion of the work week will approach the upper 90's.

High pressure regains control of our weather by the new weekend, with Monsoon moisture and isolated storms returning to southern Arizona.
