TUCSON - From a perfect May day to a slight thunder threat in 24 hours.
The weather focus this week will be an area of low pressure near Rocky Point, according to News 4 Meteorologist Jeff Beamish. After daytime highs Monday reach the upper 80's in Tucson, some moisture sneaks in from the south and east. This leads to a chance of isolated thunderstorms in the higher terrain east of Tucson starting Tuesday.
Very little rainfall is anticipated with these storms, thanks to dry air at the surface. Because of this, the wildfire threat will increase due to lightning strikes. Low pressure moves east of the state by Friday, ending the chance of thunderstorms.
High temperatures Tuesday through Thursday only peak in the mid 80's, which is below average for this time of year.
The upcoming weekend looks rather warm, as highs near 100 in the western deserts. The Tucson metro should top out in the mid to upper 90's Saturday and Sunday under abundant sunshine.
