FORECAST:

A cool upper trough pushes in for today with mostly cloudy skies in a Westerly-South Westerly flow aloft. The freezing level will drop down to around 2200 m and hover in that range until Wednesday, rising back up to around 3000 m. Likely see some sunny breaks today as well and a chance of some isolated showers. Overcast with some periods of light precipitation for Tuesday with cool temperatures. Possibility of a dusting in the upper elevations. Weak ridging returns Wednesday with a mix of sun and cloud and warmer temperatures. Could see mostly sunny skies later in the afternoon. Ridging strengthens Thursday into Friday with mostly sunny skies with some cloud in the mix. Saturday at this time looks good with a mix of sun and cloud but a trough is moving in for Sunday with periods of light rain. Timing of the trough could change so we may see some rain later in the day Friday and Saturday, time will tell.  Guesstimates: 0-trace mm by Tuesday am, trace-3 mm by Wednesday am, 0 mm by Thursday am, 0 mm by Friday am, 0 mm by Saturday am, 0-? mm by Sunday am, 0-2 mm by Monday am.
