Temperatures fall and clouds increase early this week.

An upper level system will move into the region which will in bring cooler air aloft from the northwest.  Temperatures will be slightly below average – think highs in the mid 70s for the valley – and we’ll run the risk of seeing some showers.  The best chance for any showers will be in the mountains with thunderstorms a possibility tomorrow afternoon, but more likely on Monday as the trough axis is directly overhead.  There is a slight threat of some downpours that could have some thunder and lightning involved and with them hail is always a possibility – especially in the NorthState.  The threat of hail will decrease on Tuesday with the ridge departing but there is still the chance that an embedded thunderstorm could produce some small hail.

As we move into Tuesday a ridge will build back in that will clear out the clouds and push temperatures back up above average.  The upper level trough will eventually form an “omega block” which will keep our weather pretty consistent from Wednesday onward until the blocking pattern breaks.  Highs will start to rise into the middle of the week as the ridge intensifies and by the weekend we’ll be back into the low 90s.
