12:27 P.M. UPDATE: A Flash Flood Warning has been issued for Armstrong County until 2:15 p.m.
Showers and thunderstorms will threaten the area Monday with the potential for producing locally heavy downpours, flash flooding, gusty winds and small hail. Highs will be near 80 degrees.
Tonight, a few passing showers are possible but storms should wind down. Lows will be in the low 60s.
Tuesday will bring showers and thunderstorms once again in the afternoon as peak heating and a low-pressure system overhead fuel the storm chances.
Wednesday looks to be the best day of the week, weatherwise, with a mostly sunny sky and highs in the low 80s.
Unsettled weather once again returns Thursday and Friday.
