TUCSON - Hot & mainly dry again this afternoon, but don't put the umbrellas away yet.
For the 51st time this year, Tucson reaches triple digit territory for highs. There is a slight chance of a late day/early evening storm, according to 4WARN Meteorologist Jeff Beamish. Favored areas for isolated storms this afternoon appears to be Cochise County.
Winds aloft shift from the southwest to the south tomorrow, allowing ample moisture to move into the Sonoran Desert. Scattered storms are possible Wednesday along and east of an Oracle-Tucson-Nogales line. Locally heavy rainfall and gusty winds are the primary storm threats tomorrow.
After tomorrow, the Monsoon quiets down. Dry air leads to only isolated storm chances Thursday into early next week. As the atmosphere dries out, temperatures heat up. Triple digit heat is expected Friday through Monday.
