FORECAST:

A weak upper trough will bring overcast skies and showers to the area today in a Westerly flow aloft. The warm front moving onshore should get the FL to around 1800 m this afternoon, dropping back down tonight to 1500 m with the trailing cold front pushing through. Likely see a few breaks today as well.  Ridge builds for Tuesday with mostly sunny skies. Ridge and low are battling it out on Wednesday, feel like it will be a mostly cloudy dry day with warm air pushing into the zone. A significant upper low will push through on Thursday with warm temps and light precipitation. As it exits Friday we will likely see unsettled weather with a mix of sun and cloud with more May showers. Lingering low will bring cloudy weather for Saturday with more showers. As of now it looks like the ridge rebuilds for Sunday with sunny skies. Never easy to produce a weekly forecast, will be interesting to see how far off it will be by next Monday. Guesstimates: trace-1 mm by Tuesday am, 0 mm by Wednesday am, 0 mm by Thursday am, 10-15 mm by Friday am, 1-3 mm by Saturday am, nil-trace by Sunday am, 0 mm by Monday am.
