Unsettled weather for this morning as the low to our South sends cloud our way with a weak ridge trying to build from the North. Ridge will strengthen for Monday with more sun than cloud. The FL should hover at around surface for the next 2 days. A weak front will push in on Monday night into Tuesday, exiting Wednesday morning with light precipitation and the FL rising as high as 1500 meters. Looks like we will be in an unsettled pattern after that into the weekend. Guesstimates: 1-3 cm by Tuesday morning, 8-12 cm by Wednesday morning.
